Description

Device for operating a roof screen assembly and motor vehicle roof

Technical Field

The present invention relates to a device for operating a roof screen assembly. The invention also relates to a roof for a motor vehicle having such a device.

Background

Some motor vehicles have screen assemblies that can provide entertainment on demand and help to improve the comfort of the motor vehicle. If desired, such a screen assembly may be provided with a kinematic scheme that enables the screen assembly to be folded in and out as desired. The challenge here is how to arrange such entertainment electronics in a space-saving and cost-effective manner and to increase the comfort of the motor vehicle.

Disclosure of Invention

The object of the present invention is to provide a device for operating a roof screen assembly, which can be realized in a space-saving manner and which contributes to an increased comfort of the motor vehicle.

The object is achieved by the features of the independent claims. Advantageous developments are given in the dependent claims.

The inventive device for operating a roof screen assembly comprises a transverse carrier which is designed to be coupled to the roof such that the transverse carrier extends essentially transversely to the longitudinal axis of the roof. The device also has a rollable display screen that can be unrolled and rolled up by a display screen shaft and coupled to the lateral carrier. The device further comprises a guide mechanism which is coupled to the transverse carrier and comprises a plurality of guide levers which are coupled to the display screen and are provided for tensioning the display screen when unreeled from the display screen shaft and for clamping the display screen when wound onto the display screen shaft.

By means of the above-described device, a roof screen assembly with a rollable display screen can be realized, which is designed in a particularly space-saving manner and contributes to an improved comfort of the motor vehicle. The space required can be kept small compared to a rigid display screen and a greater degree of freedom of the head can be provided for the vehicle occupants, especially in the parked position of the display screen. Furthermore, if the roof is designed to be transparent or comprises a transparent roof element, the device can also increase the field of view through the roof.

According to a development of the device, the guide means comprise an electric drive unit and a turnstile, which is coupled to the drive unit on the one hand and to the guide lever on the other hand, so that a rotation of the turnstile can be brought about by means of the drive unit, so that a pivoting of the guide lever and a winding or unwinding of the display screen are brought about.

According to a further development of the device, the guide means comprises an electric drive unit and a lever transmission with a gear element, which is coupled to the drive unit on the one hand and to the guide lever on the other hand. By means of the drive unit, a rotation of the gear element of the lever transmission can be caused, so that a pivoting of the guide lever and a winding or unwinding of the display screen are caused.

According to a further development of the device, the guide mechanism with the lever mechanism comprises two first guide levers, two second guide levers and two third guide levers, wherein one guide lever is arranged on each of the opposite sides of the display screen with respect to the longitudinal extension of the transverse carrier and are coupled to each other in a pivotable manner on the respective side. The first guide levers are also swingably coupled with the respective gear elements, so that one of the first guide levers with the first gear element has a first pivot axis and the other first guide lever with the second gear element has a second pivot axis. The guide lever, the gear element and the rotation axis are arranged such that the rolled-up state of the two pivots relative to the display screen can be arranged between the transverse carrier and the rotation axis of the gear element.

The drive unit for the turnstile and/or the lever transmission can be designed in particular as a central drive with an electric motor. Both the turnstile and the lever actuator enable reliable and safe tensioning and retraction of the rollable display screen by the guide lever. The lever transmission can be arranged more flat in the retracted parking position under the roof or on or in the transverse carrier, for example by means of the arrangement described above, than a turnstile.

In this description, terms such as "upper", "lower", "front", "rear", "upper", "lower" and "horizontal" and "vertical" refer to the direction or orientation of a motor vehicle with a roof and devices arranged on the roof in a ready-to-run state. Thus, in the rolled-out state, the lower edge of the display screen faces the vehicle interior space. The usual direction of travel is forward, while the vehicle tail is arranged in the rear. Thus, the arrangement under the roof faces the vehicle interior.

According to a development, the one or more guide levers are designed as elongate bending or articulated connections and have a predetermined bent longitudinal shape in coordination with the rolled and/or unrolled state of the display screen. The guide lever is provided in particular as a lateral bending connection and can be moved from a retracted bending position into an extended position and back, and can also serve as a hidden lateral shielding device and provide a predetermined line of sight protection.

According to a further development of the device, the guide lever is coupled on the one hand to the drive unit and on the other hand to the fixing unit, which is coupled in the form of a beam to the display screen along the lower edge of the display screen, so that the fixing unit can be moved away from the transverse carrier by means of the guide lever and the display screen can be unwound and can be moved towards the transverse carrier and the display screen can be wound up.

The rollable display which can be rolled up and unrolled in operation is preferably realized as an OLED display. Alternatively, the rollable display screen may also be designed as a micro LED display screen or an electronic paper display screen.

The device may furthermore comprise a shielding element, for example in the form of a textile curtain or a non-transparent layer, which can be wound up and unwound by means of a shielding shaft. The shielding shaft is coupled to or integrated in the transversal carrier such that the shielding element faces the rear side of the display screen and covers said rear portion in a predetermined manner when the display screen is rolled up and unrolled.

According to a further development, the device comprises a guide system with a transverse-carrier guide element, in particular in the form of a guide rail, which can be coupled to the vehicle roof on opposite sides with respect to the longitudinal axis, so that the transverse carrier can be moved in a predetermined manner along the longitudinal axis with interaction with the transverse-carrier guide element with respect to the vehicle roof.

The roof for a motor vehicle according to the invention comprises a roof element which is provided for coupling with a roof body of the motor vehicle. The vehicle roof according to the invention further comprises one of the embodiments of the device for operating a screen assembly described above, which is coupled to the roof element on the side of the roof element facing the interior space of the vehicle. The device can be connected directly or indirectly to the roof element via a transverse carrier. The transverse support can be coupled to the vehicle roof as a stationary transverse support or can be configured to be movable relative to the vehicle roof. The transverse carrier and the display screen arranged on or integrated in the transverse carrier can thus be moved in a predetermined manner along the longitudinal axis under the roof and, for example, can be moved to the forefront or rearmost in the motor vehicle.

For example, the roof element may be realized as a roof system with a glass roof or as a panorama glass roof. Alternatively, the roof element may also form a non-transparent roof skin of the vehicle roof. The roof element may be designed to be liftable or deployable and/or may be fixed to the roof body or movable relative thereto.

Since the roof comprises embodiments of the device, the features and characteristics of the device are also applicable to the roof and vice versa.

The device and the associated roof assist in improving the comfort of the motor vehicle. The rollable display screen can be accommodated in a particularly space-saving manner and the field of view through the roof can be increased. Furthermore, a particularly large field of view through the roof can be achieved by the movable transverse carrier. The guide mechanism provides a stable and reliable guide linkage for the rollable display screen and also orients the lower edge of the rollable display screen to a certain extent at a desired height level.

Detailed Description

Fig. 1 schematically shows a roof 2 of a motor vehicle 1 in a perspective view, which roof comprises a roof element, a roof system or a roof 4 for closing a roof opening in the roof 2. For example, the roof 4 is a fixed glass element that is not movable relative to the roof 2. Alternatively, the roof 4 is movable relative to the roof 2 in order to selectively open and close a roof opening in the roof 2. The roof 2 may also be free of the roof cover 4, but instead employ a roof skin without a recess, for example a foldable or foldable convertible roof, which can be accommodated in the rear region of the motor vehicle 1. Furthermore, the roof 2 can also form a convertible top with a roof cover 4, wherein the roof cover 4 is designed such that folding or folding can be achieved.

Below the roof 2, a transverse carrier 13 is arranged, which is configured to be movable relative to the longitudinal axis L. The transverse carrier 13 implements a type of bearable beam or cross-beam that is coupled directly or indirectly to the roof 2 and/or roof 4.

In the context of the present description, the terms "upper", "lower", "front", "rear", "upper", "lower" and "horizontal" and "vertical" denote the direction or orientation of the motor vehicle 1 with the roof 2 in the operating readiness state as shown in fig. 1. Thus, the horizontal plane is spanned by the x-y plane shown and oriented perpendicular to the z direction shown, which represents a vertical line. The longitudinal axis L corresponds to the longitudinal axis of the vehicle, and the arrow direction shown represents the normal direction of advance. The tail is disposed or formed at the rear. The transverse support 13 is thus arranged below the roof 2 and/or integrated in the roof 2 and faces the interior of the motor vehicle 1.

As explained with reference to fig. 2 to 68, which follow, the individual devices 10, 20, 30, 40, 50, 60 and 70 make it possible to achieve a comfortable operation, orientation and packing of the screen assembly, which is coupled to the transverse carrier 13, arranged on the transverse carrier 13 and/or integrated in the transverse carrier 13. These means 10 and/or 20 and/or 30 and/or 40 and/or 50 and/or 60 are particularly advantageous interactions but may also be provided separately to provide the respective functions.

By means of these devices 10 to 70, a screen assembly for the vehicle roof 2 can be realized, which has at least one display screen 11, 12, which can be constructed in a particularly space-saving manner and which contributes to an increased comfort of the motor vehicle 1.

Fig. 2-12 show an embodiment for operating the screen assembly 10 for the vehicle roof 2 in different views. Other views and/or components of device 10 and/or devices 20, 40 and/or 70 are shown in fig. 13-16.

According to fig. 2, the roof 4 is preferably designed as a transparent roof element which allows a view through the roof 2. For example, the roof 4 is designed as a transparent pane and forms a panoramic roof which is fixedly connected to the roof body 3 of the motor vehicle 1. In fig. 2, the device 10 is arranged in the rear or rear region of the roof 2, or is moved backwards and retracted.

The device 10 comprises a rollable display 11 which can be rolled up or unrolled by a display shaft 14 and which is coupled to a transverse carrier 13. The display screen shaft 14 is coupled to the transversal carrier 13 by a shaft connection 16 (see fig. 10-13). The transverse carrier 13 is coupled to the vehicle roof 2 such that it extends mainly transversely to said longitudinal axis L. The main or longitudinal direction of extension of the transverse carriers 13 thus essentially leads from one side of the roof 2 to the other side of the roof 2.

The rollable display 11 is realized in particular in the form of an OLED display, which is also referred to as first display 11 if necessary in the following description. The rollable display screen 11 may be designed as a flexible screen, which may be rolled up or bent completely or partially. In addition to the first display screen 11, the device 10 has a further display screen 12 which is coupled to the transverse carrier 13 at a distance from the first display screen 11 with respect to the longitudinal direction of the transverse carrier 13. The further display 12 is designed as a rigid display, and is also referred to as a second display 12 in the following description if necessary.

In this respect it is pointed out that according to a preferred embodiment, the device 10 comprises two rollable displays instead of one rollable display 11 and one rigid display 12, which are coupled side by side with the transversal carrier 13 or integrated in the transversal carrier 13. However, for ease of illustration, the advantages of the configuration of the first rollable display screen 11 in combination with the rigid second display screen 12 are described or illustrated below.

Fig. 3 shows the vehicle roof 2 without the transparent roof 4, wherein the transverse carrier 13 is moved completely backwards and the first and second display screens 11 and 12 are retracted or put in. Since the first display 11 is a rollable display, the illustrated rest or parked position corresponds to a rolled-up state in which the first display is disposed at least substantially around the display axis 14. The rolled-up state may also be referred to as a rest state of the first display screen 11. Further, the rolled state may also be referred to as a put-in, retracted, clamped, rolled-up, or retracted state of the first display screen 11.

Since the second display 12 is a rigid display, the illustrated rest or parking position corresponds to a folded-in state in which the second display 12 is folded up and extends substantially along the roof 2 or roof cover 4. The folded-in state may also be referred to as a resting state of the second display 12. In addition, the folded-in state may also be referred to as a put-in, retracted, folded-up, or retracted state of the second display screen 12.

Fig. 4 shows an intermediate position, which is provided by moving the transverse carrier 13 forward until the desired position under the roof 2 or the roof 4 is reached. Furthermore, the two displays 11 and 12 are each shown in a respective unfolded state in which they are in operational readiness for outputting entertainment.

The unfolded state of the first display 11 may also be referred to as an operational state. Furthermore, the unfolded state may also be referred to as an extended, stretched, rolled-out or unrolled state of the first display screen 11. The unfolded state of the second display 12 may also be referred to as an operational state. Furthermore, the unfolded state may also be referred to as a folded-out, folded-down or extended state of the pivotable second display screen 12.

The display screens 11 and 12 are oriented such that their respective luminous front sides face in the rear direction relative to the extended state in the operating mode. The device 10 has a rollable display 11 on the left side of the transverse carrier 13 and a rigid display 12 on the right side with respect to the longitudinal axis L shown. Other arrangements may also be employed.

Fig. 5 shows a further perspective view of the device 10, in which the transverse carrier 13 is moved completely forward with respect to the longitudinal axis L and the travel direction shown. The two displays 11 and 12 are still in the respective operating state. Such a foremost position of the transverse carriers 13 is very useful, for example, if the motor vehicle 1 is designed as an autonomous vehicle and autonomous is achieved. Furthermore, such a recreation position of the display screens 11, 12 can also be provided when the motor vehicle 1 is stationary, for example for a rest.

The movability of the transverse carriers 13 is achieved by means of the guiding system 60, in this connection, in particular, reference being made to the following description in connection with fig. 64-68.

The projecting display screens 11 and 12 on the movable transverse carrier 13 are shown in fig. 6 in an oblique rear view. Fig. 7 shows a corresponding view of the display screens 11 and 12 projecting from above, wherein the transverse carrier 13 obscures the view to the display screens 11 and 12.

The retracted display screens 11 and 12 on the movable transverse carrier 13 are shown in an oblique rear view in fig. 8. Fig. 9 shows a corresponding view of the retracted display screens 11 and 12 from above. The advantage of the rollable display 11 is immediately visible in fig. 9, since the rollable display 11 can be stowed in a particularly space-saving manner and does not protrude beyond the transverse carrier 13 in the x-direction or the longitudinal axis L. A particularly large field of view through the cover 4 can thus be achieved, which corresponds to, for example, half the length or height of the rigid display screen 12. Thus, the rollable display screen 11 may facilitate a screen assembly that may expand the field of view and provide structural space advantages over an eversible rigid display screen.

Fig. 10 and 11 illustrate one embodiment of a display screen shaft 14 upon which the rollable display screen 11 may be rolled or from which the rollable display screen 11 may be rolled out. The display screen axis 14 is cylindrical and is designed to be rotationally symmetrical. The display screen shaft 14 is configured as a hollow shaft and encloses a shaft 15. Shaft connectors 16 are disposed on opposite sides of the display screen shaft 14 and are coupled to the shaft 15.

A plurality of tensioning elements in the form of drive springs 17 are arranged between the display screen shaft 14 and the shaft 15. Three drive springs 17 are arranged at opposite free ends, respectively, with respect to the longitudinal extension of the display screen shaft 14. The drive springs 17 are coupled to the display screen shaft 14 on the one hand and to the shaft 15 on the other hand, respectively, and are provided for tensioning the display screen 11 in a predetermined manner when the display screen 11 is unwound from the display screen shaft 14 and wound onto the display screen shaft 14. The drive spring 17 is a preferred variant of an internal spring element which helps to run and house the rollable display 11 with little space and provides a useful force for tensioning the rollable display 11.

In particular, the rollable display 11 and the display axis 14 are configured to be matched to one another in such a way that they together have a diameter in the range of 40 to 100 mm with respect to the rolled-up state and a radial direction transverse to the longitudinal extension of the display axis 14.

Fig. 12 shows the device 10 with the transverse carrier 13 and the display screen shaft 14 in a side partial sectional view. The transverse carrier 13 has a housing 131 in which the display screen shaft 14 is arranged. Thus, when the rollable display 11 is wound on the display shaft 14, it may be disposed hidden in the housing 131. Fig. 12 shows an extended state of the rollable display screen 11. Fig. 13 shows a retracted state of the rollable display screen 11.

Additional moving parts are also shown in fig. 12-16, which control, for example, the extending movement of the rollable display screen 11. The device 20 capable of this function is also referred to as a guide mechanism 20, and will be described below in connection with fig. 17-27. In addition, the device 40 and its elements are also shown in fig. 12-16. The device 40 is also referred to as a fixation unit 40, in this connection reference being made in particular to fig. 43-45 and the related description. Furthermore, the figure shows the components of a device 70, which is also referred to as a shielding unit 70 and which provides the display screen 11 with a foldable and foldable covering. The shielding unit 70 will be described below with reference to fig. 69-75 in particular.

The device 10 further comprises a shielding element 19, for example in the form of a roller blind, which can be rolled up and unrolled by means of a shielding shaft 18. The shielding shaft 18 is coupled to the transverse carrier 13 and is arranged in a housing 131 like the display screen shaft 14. The shielding element 19 is assigned to the rear side 112 of the rollable display 11 such that it covers the rear side 112 in a predetermined manner when the first display 11 is rolled up and unrolled.

The shielding element 19 is coupled on the one hand at the upper end with the shielding shaft 18 and on the other hand at the lower end with the fixing unit 40. The same is true of the rollable display 11, which is coupled on the one hand to the display shaft 14 at the upper end and on the other hand to the fixing unit 40 at the lower end (see fig. 16). When the shielding element 19 and the rollable display 11 are unreeled, the fixing unit 40 is moved away from the transverse carrier 13 by means of the guiding mechanism 20, and when the shielding element 19 and the display 11 are rolled up, the fixing unit 40 is moved towards the transverse carrier 13. The shielding shaft 18 and the display screen shaft 14 are configured to be matched to each other, so that the shielding element 19 and the display screen 11 can be wound and unwound simultaneously.

Fig. 14 and 15 show the extended and retracted state of the first rollable display screen 11 similar to fig. 12 and 13, with the view being to the moving parts of the guide mechanism 20, without the first display screen 11 and the shielding element 19 being shown. The guide mechanism 20 allows reliable unreeling and stable tensioning as well as reeling and clamping of the rollable display 11 and the shielding element 19. For this purpose, the guide mechanism 20 has a plurality of guide levers 21, 22, 23 which can be moved electrically by means of a drive unit 24. The drive unit 24 is in particular designed as a central drive with an electric motor.

According to fig. 12, some of the guide levers 22, 23 are also designed as lateral shielding elements 72, 73 or coupled with such shielding elements in order to create an aesthetically pleasing lateral termination or line of sight protection for the rolled-out display screen 11. In particular, the illustrated shape of such a shielding element facilitates a comfortable line of sight protection and reliable operation of the guiding mechanism 20. The shielding element 19 forms a rollable line of sight protection which in the extended state conceals wiring and/or electronic actuation components of the rollable display screen 11. The guide levers 22 and 23 accordingly form a lateral line-of-sight protection as side-foldable shutters on opposite sides of the rollable display 11. As shown in fig. 12, the tensioned state of the unwound display screen 11 is achieved in particular by a drive spring 17 in the display screen shaft 14. Accordingly, as shown in fig. 12, the tensioned state of the unreeled shielding element 19 can be achieved by a spring element in the line of sight shielding shaft or shielding shaft 18.

Fig. 17-27 show, in different views, an embodiment of the vehicle roof 2 with the device 10 and the guiding mechanism 20 for controlled extension and retraction of the rollable display screen 11. Fig. 17 to 21 show in perspective views the different positions and states of the device 10 and the guide 20 for operating the screen assembly. Fig. 22-27 show an embodiment of the guide mechanism 20 in more detail.

For clarity, only the rollable display 11 is illustrated in fig. 17-27. Thus, the guide mechanism 20 will be described in connection with the rollable display screen 11. However, the further second display screen 12 is preferably arranged as a further rollable display screen beside the first rollable display screen 11 on the lateral carrier 13.

Fig. 17 shows a parked position of the device 10 in which the device 10 is received in the rear area of the vehicle and the display screen 11 is retracted.

Fig. 18 shows the device 10 in a first intermediate position, in which the display 11 is still retracted or rolled up.

Fig. 19 shows the device 10 in a first intermediate position shown in fig. 18, with the display 11 extended or unfolded.

Fig. 20 shows the device 10 in another position in which the transversal carrier 13 is moved completely forward and the display screen 11 is retracted or rolled up.

Fig. 21 shows the device 10 in the forward-most position shown in fig. 20 with the display 11 extended or unfolded.

The device is extended or deployed and again retracted or clamped by means of the guide mechanism 20, the guide mechanism 20 being configured as shown in fig. 22-27. The guide mechanism 20 of fig. 22 and 23 includes a turnstile 25. Fig. 24-27 show an alternative embodiment of the guide mechanism 20, according to which the guide mechanism 20 has a lever transmission 26.

The guide mechanism 20 is coupled to the transverse carrier 13 and comprises a plurality of guide levers 21, 22, 23 which are coupled to the rollable display 11 and are provided for tensioning the display 11 when the display 11 is unwound from the display axis 14 and for clamping the display 11 when the display 11 is wound onto the display axis 14. A first guide lever 21, a second guide lever 22, and a third guide lever 23 are provided with respect to the right and left sides of the display screen 11, respectively. Therefore, one side of the guide mechanism 20, the characteristics of which can be transferred to the other side accordingly, will be mainly described hereinafter. The differences may be pointed out with reference to the guide mechanism 20 or the left and right sides of the rollable display screen 11, if necessary.

The first guide lever 21 is coupled pivotably on the one hand to a turnstile 25 or a lever drive 26 and on the other hand to a second guide lever 22, which can also be designed specifically as a shielding element (see fig. 12). On the right, the coupling position of the first guide lever 21 with the turnstile 25 or the lever actuator 26 forms a first pivot S1. On the left side, the coupling position of the first guide lever 21 with the turnstile 25 or the lever actuator 26 forms a second pivot S2.

The second guide lever 22 is coupled pivotably on the one hand to the transverse carrier 13 and on the other hand to the third guide lever 23. The coupling of the second guide lever 22 to the transverse carrier 13 can be effected directly or indirectly. The third guide lever 23 is coupled pivotably to the second guide lever 22 on the one hand and to the fixing unit 40 on the other hand.

The guide mechanism 20 and the guide levers 21, 22, 23 can be actuated by means of a drive unit 24, respectively, and can be folded out and in electrically. The electric drive unit 24 is arranged on the transversal carrier 13 and is for example integrated in a housing 131 and coupled with the turnstile 25 or the lever transmission 26. By means of the drive unit 24, a rotation of the turnstile 25 or the lever transmission 26 can be initiated, so that a pivoting of the guide levers 21, 22, 23 and a reeling or unreeling of the rollable display 11 is initiated.

The first and second guide levers 21 and 22 are designed in terms of their shape as elongated bent links, while the third guide lever 23 is designed in a straight line. This preferred arrangement facilitates a particularly space-saving folding in of the guide 20 and a stowing of the rollable display 11. The guide levers 21, 22, 23 can be designed in particular as stable and narrow metal parts in order to reliably unwind and tension the display screen 11 and fold in and receive it in a space-saving manner. Alternatively, one or more of the guide levers 21, 22, 23 can also be embodied as plastic parts.

The guide mechanism 20 forms a scissor mechanism by means of which the pivots S1 and S2 and the guide levers 21, 22, 23 are guided in a controlled manner. As shown in fig. 22 and 23, the pivots S1 and S2 can be guided one above the other by a scissor mechanism with a turnstile 25. Fig. 22 shows the retracted or folded-in state of the scissor mechanism, in which the display 11 is rolled up and the guide levers 21, 22, 23 are retracted in the folded position. In this state, the second pivot shaft S2 is arranged above the first pivot shaft S1 with respect to the vertical line. The rotation axis R3 of the turnstile 25 is formed or arranged between the two pivots S1 and S2. Fig. 23 shows the extended or folded-out state of the guide mechanism 20 in the form of a scissor mechanism as shown in fig. 22, in which the display screen 11 is tensioned and the guide levers 21, 22, 23 are oriented in the extended position. Thus, in the retracted and extended states, the pivots S1, S2 are located one above the other and above the rotation axis R3 of the turnstile 25.

As shown in fig. 24 to 27, the guide 20 in the form of a scissor mechanism with a lever mechanism 26 makes it possible to achieve a more space-saving arrangement of the display screen 11 in or on the transverse carrier 13 than in the embodiment with a turnstile 25. The lever transmission 26 comprises two gear elements 27 and 28, which are coupled to the drive unit 24 on the one hand and to the first guide lever 21 on the other hand. The first gear element 27 is rotatable about a first rotational axis R1 and the second gear element 28 is rotatable about a second rotational axis R2. The gear elements 27 and 28 cooperate with each other in their tooth configuration, so that the drive unit 24 only has to drive one gear element, so that the respective other side of the guide levers 21, 22, 23 can also be moved. Alternatively, both gear elements 27 and 28 may be driven by the drive unit 24, or an embodiment may be employed in which the gear elements 27 and 28 are not in contact with each other. By means of the drive unit 24, the gear elements 27 and 28 of the lever transmission 26 can be rotated, so that the guide levers 21, 22 and 23 are pivoted and the rollable display 11 is rolled up or unrolled.

Fig. 24 shows the retracted or folded-in state of the scissor mechanism with lever gear 26, in which the display screen 11 is rolled up. In this state, the two pivots S1 and S2 are at substantially the same height with respect to the vertical line and are located above the rotation axes R1 and R2 of the gear elements 27 and 28. Thus, the fixing unit 40, which is coupled to the rollable display screen 11 at its lower edge 111, may be moved to a position closer to the underside of the drive unit 24 than in the embodiment with the turnstile 25. The fixing unit 40 may be partially or completely coupled with the rollable display screen 11 along the lower edge 111. Thereby, the guide mechanism 20 and the rollable display screen 11 can be accommodated particularly flat on the underside of the roof 2, and a greater degree of head freedom can be provided for the passenger.

Fig. 25 shows the extended or folded-out state of the guide mechanism 20 in the form of the scissor mechanism shown in fig. 24, in which the two pivots S1 and S2 are located approximately at the level of the rotational axes R1 and R2 or slightly below the rotational axes R1 and R2.

The guide levers 21, 22, 23 are coupled on the one hand with the drive unit 24 and on the other hand with the fixing unit 40 which is coupled with the rollable display 11 along its lower edge 111. Thus, when the display screen 11 is rolled up, the fixing unit 40 is moved towards the transversal carrier 13 by means of the guiding levers 21, 22, 23. As described above with reference to fig. 12-16, the shielding element 19 may also be unwound from its shielding shaft 18 by means of a guiding mechanism 20 and then wound onto the shielding shaft 18.

Fig. 26 and 27 show perspective views of the guide mechanism 20 with the lever actuator 26 in the retracted state shown in fig. 24 and in the extended state shown in fig. 25, respectively. In addition, the figure shows the components of the guiding system 60, which allow the lateral carriers 13 to be moved. In this regard, reference is made to the following description of FIGS. 64-68.

The guide mechanism 20 provides a space-saving and reliable guide linkage for the rollable display screen 11. The guide 20 is designed in particular such that a continuous extension and retraction of the rollable display 11 can be achieved, so that a desired intermediate position can also be provided in which the rollable display 11 is not fully retracted or extended. Thus, for example, the lower edge 111 of the rollable display screen 11 can be set to a desired height in the in-vehicle space. Alternatively, the guide mechanism 20 may also provide a plurality of predetermined intermediate positions so that the display screen 11 can be gradually extended and retracted. Alternatively, the guide mechanism 20 may be designed such that the display screen 11 is only fully retracted or extended.

Fig. 28-42 show the device 30 in different views, which will also be referred to as tilting mechanism 30 hereinafter. The tilting mechanism 30 may achieve a dual tilt position of the first rollable display screen 11 and the second rigid display screen 12. Accordingly, the display screens 11 and 12 can be tilted or inclined in a targeted manner with respect to the horizontal first plane EA1 and with respect to the vertical second plane EA2 (see fig. 33 and 35).

Fig. 28 shows the vehicle roof 2 in a top view, with the two display screens 11 and 12 retracted into the parking position.

Fig. 29 shows the intermediate position of the transversal carrier 13 in a perspective view, with the display screens 11 and 12 retracted. Fig. 30 shows the roof 2 shown in fig. 29 in a top view.

Fig. 35 shows a section view of the retracted display screens 11 and 12 looking rearward along the second plane EA 2. Fig. 36 shows a perspective view of the roof 2 shown in fig. 35.

Fig. 37 and 38 show the roof 2 shown in fig. 35 and 36 in a rearward view, with the display screens 11 and 12 extended.

Fig. 38A and 38B schematically show the moving parts for folding out and folding in and for tilting the second rigid display screen 12 in the folded out and folded in position.

Fig. 39 and 40 show in a side sectional view perpendicular to the longitudinal axis L a movement assembly L for folding out and in and for tilting the second rigid display screen 12. In fig. 39, the second display 12 is folded up or in, and in fig. 40, the second display 12 is partially or fully folded down or out. The desired inclination of the second display 12 with respect to the vertical can be set by means of the lever mechanism 37.

Fig. 41 and 42 show in a sectional view along the longitudinal axis L the moving parts for folding out and in and for tilting the first flexible display screen 11. In fig. 41, the first display 12 is retracted or rolled up, while in fig. 42, the second display 12 is fully extended and tensioned.

The tilting mechanism 30 comprises a plurality of guiding elements 31-36 coupling the respective display screen 11 or 12 with the transversal carrier 13. The guide elements 31-33 are assigned to the second display screen 12 and may also be referred to as first, second and third transverse carrier couplings 31-33. The guide elements 34-36 are assigned to the first display screen 11, which comprise a slotted guide element 34, a slotted track 35 and a guide pin 36.

The guide elements 31 to 36 are provided for orienting the respective display screen 11, 12 with respect to the associated lower edge 111, 121 along the first axis A1, A2 in the unfolded state and along the second axis A3, A4 in the retracted state. The first axes A1, A2 are oriented in a first plane EA1, which first plane EA1 is spanned by the longitudinal axis L and the longitudinal extension of the transverse carrier 13. The first plane EA1 corresponds to a horizontal plane. The first axis A1 of the first display screen 11 and the first axis A2 of the second display screen 12 may be arranged such that they form an angle of less than 90 ° with the longitudinal axis L, respectively, in the unfolded state (see fig. 32 and 33). The smaller angle between the axis A1 or A2 and the longitudinal axis L is referred to herein as the included angle. Therefore, according to fig. 32, the angle of the upper right (toward the rear of the vehicle) or lower left (toward the front of the vehicle) of the illustrated intersection point of the axis A1 and the longitudinal axis L is referred to as an included angle. Accordingly, for the axis A2, the angle of the upper left (toward the front of the vehicle) or the lower right (toward the rear of the vehicle) is referred to as an included angle.

The second axes A3, A4 of the display screens 11, 12 are oriented in a second plane EA2, which second plane EA2 is perpendicular to the first plane EA1 and represents a perpendicular plane perpendicular to the longitudinal axis L. The second axis A3 of the first display 11 and the second axis A4 of the second display 12 may be set such that they form an angle of more than 0 ° with the first plane EA1 in the retracted state (see fig. 29, 35 and 36). The smaller angle between the axis A3 or A4 and the horizontal plane EA1 is also regarded here as an angle. Therefore, according to fig. 35, the angle with respect to the intersection of the axis A3 and the horizontal plane EA1 (not shown for clarity), lower right (toward the vehicle outside) or upper left (toward the vehicle center) will be referred to as the included angle. With respect to the axis A4, the angle of the lower left (toward the vehicle outside) or the upper right (toward the vehicle center) will be referred to as an included angle.

Accordingly, the display screens 11 and 12 are settable to a predetermined tilt position along the first axes A1, A2 in the unfolded state, and are settable to a predetermined tilt position along the second axes A3, A4 in the retracted state.

The first axes A1 and A2 take into account the viewing direction or line of sight of a vehicle occupant, who is typically not sitting directly in front of the respective display screens 11 and 12 in the motor vehicle 1, but rather slightly offset from the center of the display screens. Accordingly, the display screens 11 and 12 can be inclined outward toward the respective vehicle outer sides with respect to the light-emitting front sides thereof in a predetermined manner so that the line of sight substantially corresponds to the normal direction of the front sides of the relevant display screens 11 and 12 (see fig. 32).

By the possibility of setting along the second axes A3 and A4, the display screens 11 and 12 can be accommodated higher in the middle of the vehicle than in the outer regions. The display screens 11 and 12 can thus be accommodated by the tilting mechanism 30 in the parking position such that they extend essentially along the roof 2 or the roof 4. The roof 2 and the roof 4 are usually not formed flat in a horizontal plane, but have a predetermined curvature and are oriented higher in the center than in the side edges thereof with respect to the state of being mounted on the motor vehicle 1. The curvature of the roof 2 and roof 4 can be taken into account by the tilting mechanism 30 and this contributes to an increased degree of freedom in the head of the vehicle occupant (see fig. 35 and 36).

The tilting means 30 of the first display screen 11 and the tilting means 30 of the second display screen 12 are each provided for the respective second axis A3, A4 to be predetermined in coordination with the position of the roof 2 and/or roof 4 and the display screen 11, 12 on the underside of the roof 2 in such a way that the associated display screen 11, 12 follows the shape of the roof 2 and/or roof 4 in the longitudinal extension direction of the transverse carrier 13 in the retracted state and is arranged or retracted substantially parallel to the roof 2 and/or roof 4.

The tilting mechanism 30 of the first display 11 comprises a chute guide element 34 which is coupled to the transverse carrier 13 and has a chute track 35, with which chute track 35 a guide pin 36 cooperates, and within which chute track 35 the guide pin 36 can be guided in a predetermined manner. The guide pin 36 is formed on the second guide lever 22 of the guide mechanism 20 or is coupled with the second guide lever 22, and thus predefines the guide movement of the second guide lever 22 together with the first guide lever 21 when the rollable display screen 11 is extended and retracted (see fig. 41 and 42).

The tilting mechanism 30 of the second display 12 comprises a lever mechanism 37 which is coupled to the transverse carrier 13 and by means of which the second display 12 can be folded out or in. The lever mechanism 37 comprises three transverse carrier couplings 31, 32, 33 which are differently dimensioned and designed to be pivotable, so that a retracted state of the second display screen 12 can be achieved in which the lower edge 121 of the second display screen 12 is oriented along the output axis A0 (see fig. 34). The output shaft A0 is oriented in a first plane EA1 perpendicular to the longitudinal axis L. The second display 12 is thus in the retracted parking position below the vehicle roof 2, rather than being oriented obliquely in the horizontal plane. Thus, in the folded-in state, the edges of the second display screen 12 are substantially parallel or perpendicular to the longitudinal axis L. The second display 12 is tilted along a second axis A4 with respect to the horizontal first plane EA1 (see fig. 35-36).

The first lateral carrier coupling 31 swingably couples the second display screen 12 to the lateral carrier 13 and has a pivot axis S6. Said pivot axis S6 also corresponds to the pivot axis of the third transversal carrier coupling 33. Referring to the illustration shown in fig. 38A, the first lateral carrier coupling 31 is in the left-hand region and the third lateral carrier coupling 33 is arranged on the rigid display screen 12 in the right-hand region. Accordingly, the second transverse carrier coupling 32 is arranged centrally and has three pivots S7, S8 and S9. The second transversal carrier coupling 32 comprises a chute lever 321 and a further lever 322, the chute lever 321 being swingably coupled to the transversal carrier 13 on the one hand and to the chute lever 322 on the other hand. Further, the lever 322 is swingably coupled to the display screen 12 (see fig. 40). The slide lever 321 includes a slide, for example, to which a guide pin of the drive unit 24 engages, which guide pin, when driven, causes the slide lever 321 to pivot and the display screen 12 to fold in or out.

The aforementioned tilting position of the second display screen 12 can be reliably and stably set by means of the described transverse carrier couplings 31, 32, 33 and the pivots S6-S9 assigned to them. The pivots S6-S9 extend obliquely in a predetermined manner with respect to the horizontal axis to form the above-mentioned oblique position of the second display screen 12.

The tilting mechanism 30 or 37 may shift the second display 12 to an unfolded state in which the second display 12 is oriented along the first axis A2 in a predetermined tilted position (see fig. 35-40). Furthermore, the first and second display screens 11 and 12 may be unfolded by their tilting mechanisms 30 such that their lower edges 111, 121 are oriented substantially horizontally (see fig. 37-38).

Fig. 43-45 show side cross-sectional views of the device 40, also referred to as the fixation unit 40. The fixing unit 40 is coupled with the first rollable display screen 11 at a lower edge 111 and comprises a fixing beam 42 extending along the lower edge 111 of the display screen 11 and arranged to move away from the lateral carrier 13 by the guide mechanism 20 when the display screen 11 is unrolled and to move towards the lateral carrier 13 when the display screen 11 is rolled up. The fixing unit 40 tightens the rollable display 11 in interaction with the display shaft 14 and preferably also the shielding element 19 in interaction with the shielding shaft 18.

The fixing unit 40 has a carrier layer 41 coupled to the rollable display 11 at its front side 113. The carrier layer 41 is in particular designed as a film element, for example a PET film, and is in particular used to protect the display screen 11 and to connect it to the fastening beam 42 in a stable and reliable manner. In addition, it also helps to improve mechanical stability and provides scratch resistance to protect the rollable display screen 11 from surface damage. The carrier layer 41 is coupled at the underside 421 with the fixing beams 42 in a force-fitting, form-fitting and/or material-fitting manner.

The fixing beam 42 has a rounded contour in the turning region of the shielding element 19 and the carrier layer 41, so that a reliable and gentle tensioning of the respective element can be achieved. The fixing beam 42 is made of, for example, aluminum or glass fiber reinforced plastic, and has sufficient rigidity so as to be able to reliably connect and tension the display screen 11.

Like the shielding element 19, the carrier layer 41 has a plurality of fastening openings 48 into or through which fastening elements 43 can extend, which fastening elements are formed or arranged on the underside 421 of the fastening beams 42.

The fastening elements 43 and the fastening openings 48 preferably match one another in shape and number. For example, the fastening beams 42 are each embodied in the form of an elongated button as a plastic molding with the fastening element 43, which form respective lugs and are arranged equidistantly on the underside 421 (see fig. 44). Fig. 44 schematically shows a bottom view of the fixed beam 42. The fastening opening 48 is configured in the shape of an elongated hole in which the fastening element 43 is placed.

The shielding element 19 and the carrier layer 21 each have a fastening opening 48, the position of which is predefined such that the respective fastening element 43 of the fastening beam 42 passes through the relevant fastening opening 48 of the shielding element 19 and the relevant fastening opening 48 of the carrier layer 21. Thus, a force-fitting and/or form-fitting connection between the shielding element 19 and the carrier layer 41 and the fixing beams 42 can be provided. Alternatively or additionally, the shielding element 19 and/or the carrier layer 41 can also be glued to the fixing beams 42.

According to fig. 45, the carrier layer 41 and/or the shielding element 19 has a strip-shaped reinforcing element 49, for example a perforated metal strip, in the edge region coupled to the fixing beam 42. The respective edge regions can thus be reinforced in order to establish a particularly reliable and stable coupling of the carrier layer 41 and/or the shielding element 19 to the fastening beams 42.

Furthermore, the stationary unit 40 comprises display screen electronics 44 mechanically coupled to the stationary beam 42 at an upper side 422. Furthermore, the display screen electronics 44 are coupled to the rollable display screen 11 via a coupling interface 46 and a flexible circuit unit 47 in signal technology and provide the display screen 11 with predetermined electronic functions, for example in coordination with an on-board computer of the motor vehicle 1. The coupling tension between the circuit unit 47 and the display screen electronics 44 is preferably lower than the coupling tension between the carrier layer 41 and the fixing beams 42. For example, the circuit unit 47 may be designed as a flexible printed circuit electronic device or the like.

The shielding element 19 may be a textile element in the form of a roller blind, for example, or may be constructed as a non-transparent layer in order to shield electronic and/or mechanical components on the rear side 112 of the rollable display screen 11. Furthermore, the fastening unit 40 has a shielding device (Verblendung) 45, which is coupled on the underside 421 to the fastening beam 42 or to the shielding element 19 and to the carrier layer 41 in order to conceal the coupling points of these elements in an aesthetically pleasing manner. Furthermore, the shielding means 45 has a rounded contour outwards or towards the interior space of the vehicle in order to provide the passengers in the vehicle with a safe degree of freedom of the head.

Fig. 46-63 show the device 50 in different views, which is also referred to as cable storage unit 50 in the following. The cable storage unit 50 can reliably supply data and power to the first and second curled display screens 11 and 12.

Fig. 46 and 47 respectively show in perspective view the cable storage unit 50 arranged in the rear region of the roof 2. Alternatively, the cable storage unit 50 may be integrated in the front region of the roof 2.

Fig. 48-60 illustrate the cable storage unit 50 in different views.

Fig. 61-63 schematically show embodiments of possible tensioning schemes for tensionally retaining the supply cables 51, 52 of the cable storage unit 50.

The cable storage unit 50 has a first supply cable 51 and a second supply cable 52, which provide data and/or power to the display screens 11 and 12, respectively. Thus, in terms of supply technology, the first supply cable 51 may be assigned to the first display screen 11 and the second supply cable 52 may be assigned to the second display screen 12. This may include data supply and/or current supply. Alternatively and preferably, the data supply and the current supply are separate from each other, such that for example a first supply cable 51 provides the respective current supply for the two display screens 11 and 12 and a second supply cable 52 provides the respective data supply for the two display screens 11 and 12. Separate supplies are advantageous, in particular for voltage technology or tension technology reasons and for reasons of electromagnetic compatibility and/or safety. The supply cables 51 and 52 are each formed with a sheathed energy chain having a coupling structure 58 which, in cooperation with the cable guide 57, enables a stable, reliable and low-noise guidance of the supply cables 51 and 52. The unsheathed sections 56 and 59 of the supply cables 51, 52 may also be provided if such an energy chain sheath is not required.

The cable guide devices 57 are arranged on opposite sides of the roof 2 and can achieve a controllable guiding of the supply cables 51, 52 from the rearmost to the foremost end of the roof 2. In order to provide the transverse carriers 13 with such a relatively large movability, the supply cables 51, 52 are arranged one above the other in a housing 54 (see fig. 50-53). The housing 54 is provided for storing and releasing the supply cables 51, 52 and is integrated in the rear cross member of the vehicle roof 2. Alternatively, it can also be integrated on the front cross member or the deflector of the vehicle roof 2. In order to enable the supply cables 51, 52 to be guided reliably one above the other, a partition is provided in the housing 54, for example between the supply cables 51, 52, said partition forming the bottom for the upper supply cable 52. The bottom for the lower supply cable 51 is realized by the housing bottom.

The supply cables 51 and 52 are fixedly secured at the ends facing away from the respective display screens 11 and 12, for example by means of securing hooks (not shown). From this fixed end, the supply cables 51, 52 pass through the housing 54 and exit the housing 54 at the side associated therewith by means of respective diverting means 55. The steering device 55 is formed by or coupled to the housing 54 and is provided for steering and orienting the supply cables 51, 52 along the longitudinal axis L and into the cable guide 57. In particular, the steering device 55 may be formed integrally with the housing 54 and possibly the partition and the top cover by injection moulding. The supply cables 51, 52 pass through the cable guide 57 to the associated display screen 11, 12. Furthermore, the sheathing-free sections 56 of the supply cables 51, 52 are shown (see fig. 53), respectively.

The supply cables 51, 52 thus extend in sections along the longitudinal axis L inside the cable guide 57 on the respective side of the vehicle roof 2 and in sections in the housing 54, wherein the supply cables 51, 52 extend in opposite directions in the housing 54 one above the other in obliquely oriented planes E1 and E2 and each have a U-shaped change of direction in order to be able to supply a sufficiently long supply cable. Fig. 52 shows a possible movement of the two supply cables 51 and 52 with a change in the U-shape direction when the transverse carrier 13 is close to or far from the cable storage unit 50.

Fig. 56 shows a housing 54 that includes a first obliquely oriented plane E1 and a second obliquely oriented plane E2. The horizontal plane EA1 is also shown to illustrate the purposely predetermined tilt position. The first plane E1 is arranged below the second plane E2 with respect to the vertical, wherein the first supply cable 51 is assigned to the first plane E1 of the housing 54 and the second supply cable 52 is assigned to the second plane E2.

By storing the supply cables 51 and 52 obliquely in the housing 54, a useful installation is achieved and the respective supply cables 51 and 52 are transferred into a common plane EA1 outside the housing 54, so that the supply cables 51 and 52 are guided at the same level in the cable guide 57. Torsion or tension is tolerable when the supply cables 51, 52 are transferred from the respective planes E1, E2 into the horizontal plane EA1 by the deflecting device 55.

The supply cables 51, 52 each have a carriage with a slider 53, which allows the supply cables 51, 52 to be guided with low resistance in the guide channel of the associated cable guide 57 (see fig. 58-60). Supply cables 51 and 52 enter the transverse carriers 13 from the cable guide device 57 for power and data transmission and pass through the transverse carriers to the respective display screens 11 and 12 (see fig. 54). Fig. 54 shows such a connection, wherein the supply cables 51, 52 each have a sheathing-free section 59 which leads to the respective display screen 11, 12 and can be installed in a space-saving manner in the transverse carrier 13 or its housing 131. For clarity, the transverse carriers 13 and the display screens 11, 12 arranged thereon are not shown in fig. 54.

As shown in fig. 60-63, the cable storage unit 50 preferably further includes a tensioning mechanism 591, 592, 593 coupled to the respective supply cable 51, 52 and applying a predetermined tension to the supply cable 51, 52.

For example, such tensioning mechanisms are implemented in the form of tensioning links coupled to opposing carriages. Alternatively or additionally, as shown in fig. 61, tensioning elements 591, 592 are provided in the housing 54 in the region of the respective U-shaped change of the supply cables 51, 52, which tensioning elements are designed to be movable or telescopic and to exert a tension on the respective supply cable 51, 52. For example, the tensioning elements 591, 592 may be tension springs or rope connectors.

Alternatively or additionally, as schematically shown in fig. 62 and 63, a tensioning coupler may also be provided between the two supply cables 51 and 52. The two tensioning elements 591 and 592 are coupled with the associated supply cable 51, 52 and the other tensioning element 593 exerting a force such that the supply cable 51, 52 is maintained at a predetermined tension. The further tensioning element 593 may provide a torque or a pulling force acting on the two tensioning elements 591 and 592.

The tensioning scheme helps to minimize noise when moving the supply cables 51, 52, and also allows the supply cables 51, 52 to exit or enter the housing 54 under controlled and guided conditions. Furthermore, the flexible cover of the housing 54 may be designed to match the geometry of the supply cables 51, 52 and to contact or intersect the upper supply cable 52 in a predetermined manner to prevent or counteract sloshing of the supply cables 51, 52 in the housing 54.

Reliable and safe data and current supply for the two display screens 11 and 12 can also be achieved by the cable storage unit 50, when the transverse carrier 13 can be moved along the longitudinal axis L over the entire length below the roof 2 or over the maximum possible usable length. The supply cables 51 and 52 have respective lengths such that they have a length exceeding 140 cm, for example. Such a length of the supply cables 51, 52 is dependent on the corresponding movability of the transverse carrier 13, so that it is advantageous to arrange the supply cables 51, 52 one above the other in a housing 54 on a transverse beam located in front of or behind the vehicle roof 2. If a small movability is provided, so that the supply cables 51, 52 need only be provided with a movable length of, for example, 50 cm to 100 cm, they can be stored in a common, in particular horizontal, plane in the housing 54. For example, the supply cables 51, 52 may be designed to have a movable length of 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, 150 cm, 160 cm, 170 cm, 180 cm, 190 cm, or 200 cm.

Fig. 64-68 show the device 60 in different views, which is also referred to as a guiding system 60. The guiding system 60 enables a reliable and secure guiding of the transverse carriers 13 and the display screens 11, 12 arranged thereon along the longitudinal axis L.

Fig. 64 to 66 show the vehicle roof 2 and the transverse carrier 13 coupled thereto in perspective views in different driving positions. Fig. 64 shows the transverse carrier 13 in a parking position in which it is received, for example, rearmost of the rear area under the roof 2. Fig. 65 shows the transverse carrier 13 in an intermediate position, in which the display screens 11, 12 are folded up or retracted. Fig. 66 shows the transverse carrier 13 in a front position, in which the display screens 11, 12 are folded up or retracted. The transverse carriers 13 can be moved in particular continuously by means of the guide system 60, so that any number of intermediate positions can be set between the foremost position and the rearmost position as desired.

Fig. 67 and 68 show the components of the guide system 60 in perspective views, respectively. The guide system 60 has two transverse carrier guide elements in the form of guide rails 61 which are coupled to the vehicle roof 2 or can be coupled to the vehicle roof 2 on opposite sides with respect to the longitudinal axis L. The transverse carriers 13 are each coupled on opposite sides with guide brackets 64 which are arranged in corresponding guide channels of the associated guide rail 61.

The guiding system 60 further comprises an electric drive unit 63, in particular in the form of an electric motor, which is coupled to the associated guiding slide 64 via a respective drive cable 62, so that the guiding slide 64 can be driven by the drive unit 63 and the transverse carriers 13 can be moved electrically along the longitudinal axis L. Alternatively or additionally, the transversal carriers 13 may also be moved manually. As shown in fig. 67, the drive unit 63 may be arranged in a rear region of the roof 2, or alternatively may be arranged in a front region of the roof 2. In particular, the cable storage unit 50 and the guide system 60 are arranged in the roof 2 in coordination with one another.

A safe and controllable guiding of the transverse carriers 13 can be achieved by means of the guiding system 60. The display screens 11 and 12 are arranged on a transversal carrier 13, movable with the transversal carrier 13, and the comfortable position of the display screens 11 and 12 can be set for outputting entertainment. In addition, since the mobility of the lateral carrier 13 is smooth, a view through the roof 4 can be achieved without being restricted by a cross member, a rail, or other members that obstruct the view, so that the view is not obstructed in the vehicle center direction. In this way, the largest possible field of view is obtained through the roof 2, which is more comfortable especially when using a transparent panoramic roof as roof element.

Fig. 69-75 show the device or shielding unit 70 or components thereof in different views. The shielding unit 70 may visually encase the first rollable display screen 11 and cover predetermined sections to, among other things, conceal mechanical and/or electrical connections and also prevent unwanted light from shining on the rear side 112 of the display screen 11.

The shielding unit 70 has one first shielding element 71, two second shielding elements 72, two third shielding elements 73 and one fourth shielding element 74 (see fig. 71-75). The first shielding element 71 is arranged on or in the transversal carrier 13 and is coupled to said transversal carrier 13 and provides an upper connection means for the other shielding elements 72-74. The fourth shutter element 74 is coupled to the display screen 11 at its lower edge 111 and forms a lower terminal part. The second and third shielding elements 72, 73 are arranged on opposite sides, respectively, from the first shielding element 71, 74 to the fourth shielding element 74, respectively, with respect to the vertical central axis M of the shielding unit 70, and are coupled with the first or fourth shielding element 71, 74, such that the second and third shielding elements 72, 73 couple the first shielding element 71 with the fourth shielding element 74.

The fourth shielding element 74 may implement the shielding device 45 shown in fig. 13-16 and 43, or alternatively may be formed in addition to the shielding device. Thus, the fourth shielding element 74 may be coupled to the fixed beam 42, e.g. fixed with screws, clips and/or glue (see fig. 69-72). The shielding unit 70, in particular the fourth shielding element 74, is preferably designed to match the geometry and the appearance of the housing 131 of the transverse carrier 13. For example, the housing 131 and the fourth shielding element 74 have the same material, the same surface structure, a coordinated edge course and/or the same curvature, so that a uniform and particularly attractive appearance can be obtained.

In the retracted state of the rollable display screen 11 (accompanied by the retracted state of the foldable shutter unit 70), the fourth shutter element 74 closes the housing 131 of the lateral carrier 13 on the underside, so that all other components of the shutter unit 70 are hidden in the housing 131 of the lateral carrier 13. The fourth shielding element 74 at the lower end is therefore preferably adapted in a predetermined manner to the housing 131 of the transverse carrier 13 and can be formed integrally therewith or can also be deliberately contrasted therewith.

The shielding unit 70 is coupled to the transversal carrier 13 and is arranged to fold in when the display screen 11 is rolled up and to fold out when the display screen 11 is unfolded and to form a shielding frame along the side edges of the display screen 11 with respect to the side edges of the display screen 11 (see fig. 73-75).

The second and third shutter elements 72, 73, respectively, which correspond to each other, are swingably coupled to each other by a hinge element 75. Thus, a pivot axis S4 is provided at the coupling position between the second and third shutter elements 72, 73. Furthermore, the second shielding element 72 is coupled pivotably to the first shielding element 71 on the other hand. Thus, a pivot shaft S3 is provided at the coupling position between the second shutter member 72 and the first shutter member 71. Furthermore, the third shielding element 73 is coupled pivotably on the other hand to a fourth shielding element 74. Thus, a pivot shaft S5 is provided at the coupling position between the third shutter member 73 and the fourth shutter member 74.

In this way, the shielding unit 70 can be designed in the form of a foldable and collapsible shielding frame, which can provide an aesthetically pleasing lining around the display screen 11 and can also be folded in space-saving and can be accommodated in the housing 131 of the transverse carrier 13. Upon folding in, the two second and third shutter elements 72 and 73 are moved towards each other in the coupled position of the pivot S4 (see fig. 71 and 72). The pivot S4 follows a horizontal and vertical movement. The pivot S5 follows a substantially vertical movement path. The pivot S3 remains substantially stationary. If necessary, a certain movement of the pivots S3 and/or S5 in the vertical and/or horizontal direction can also be predefined, in order to retract the shielding device 70 in a predetermined tilted position, for example, as described in connection with the tilting mechanism 30 in fig. 28-42.

Furthermore, the shielding unit 70 may further comprise a fifth shielding element in the form of a shielding element forming shielding means for shielding the rear side 112 of the display screen 11. The fifth shielding element is realized in particular as the shielding element 19 described above, which can be wound and unwound by means of the shielding shaft 18 (see fig. 60-70 and 73-74). Alternatively, the fifth shielding element may also form an additional element which faces the rear side 112 of the display screen 11 and covers said rear side 112 in a predetermined manner when the display screen 11 is rolled up and unrolled.

The shielding elements 71-74 are configured in a plate-like manner and are shaped in a predetermined manner transversely to the respective thickness in terms of lateral extension in coordination with the respectively existing installation space. In particular, the second and third shielding elements 72, 73 are formed in a predetermined manner in terms of their lateral extent in coordination with the intermediate space between the unrolled display screen 11 and the fifth shielding element or shielding element 19 (see fig. 12). The shielding elements 71-74 and/or the housing 131 may be made of aluminum or plastic or may also have a material mix. Further, for example, the shade elements 72-74 may be implemented as fabric wrapped components to provide a desired appearance.

The shielding unit 70 can preferably also be configured in a manner compatible with the previously described devices 10-60. In particular, the second and third shutter elements 72 and 73 may implement the guide levers 22 and 23 of the guide mechanism 20 (see fig. 14 and 22-25). Alternatively, the second and third shutter elements 72, 73 and the guide levers 22, 23 may form separate elements such that the second and third shutter elements 72, 73 conceal the guide levers 22, 23 in a predetermined manner and provide visual protection for the internal guide mechanism 20. In addition, the folding-out of the shielding unit 70 can also be automatically controlled by the driving unit 24 of the guide mechanism 20. Alternatively or additionally, separate drive units may also be provided for folding in and folding out the shielding unit 70.

Furthermore, as shown in FIG. 75, the shape of the shielding element 70 is preferably adapted to one or more functions of the apparatus 10-60. Thus, the first shielding element 71 has a first coupling section 76 to the corresponding second shielding element 72 and an opposite second coupling section 77, which are formed differently. Accordingly, the second shielding element 72 has a coupling structure of a different design than the first shielding element 71. The first shutter element 71 also has a protrusion 78. The first shutter element 71 and the second shutter element 72 connected thereto in the illustrated embodiment are particularly suitable for reliable and compact folding of the shutter unit 70, tensioning and retracting of the display screen 11 by the guide mechanism 20 and/or predetermined tilting of the extended and/or retracted display screen 11 by the tilting mechanism 30.
