Description

The invention relates to a laterally extendable pop-up roof for vehicles, in particular for panel vans, vans or trailers. However, it can also be used on "tiny houses" - houses with very little living space - which are now widespread.

Pop-up roofs for vehicles offer additional sleeping space on the vehicle roof or generate headroom in the vehicle. They are mostly retrofitted by removing the vehicle's original roof and replacing it with the pop-up roof, which is permanently attached to the vehicle. Some new cars are also available with a pop-up roof. In a retracted, first position, which corresponds to a driving position, such pop-up roofs increase the height of the vehicle only slightly, mostly by less than 10 cm. In a second position, which corresponds to an extended state in which an upper roof shell is at least partially extended upwards, one side of the pop-up roof on the front or rear of the vehicle is increased by a height of about 1 m in the known pop-up roofs. The height of the opposite side is at most slightly increased in an open state. Under the upper roof shell, the pop-up roof includes a basic sleeping platform on which people can sleep in the second position. In order to generate additional headroom in the vehicle, this basic sleeping platform can also be folded up in the second position in addition to the upper roof shell.

The width of known pop-up roofs is based on the width of the respective vehicle roof and is therefore in the order of 2 m, which means that sleeping space for a maximum of 2 people can be generated. A lower width of the pop-up roof, which lies at the transition to the vehicle, corresponds approximately to an upper width of the pop-up roof, which corresponds to the width of the upper roof shell.

In order to generate sleeping space for a larger number of people, in particular 4 people, the lower width of the pop-up roof would have to be increased in the second position.

Such an increase are in a conventional construction with the features mentioned, as from the EP 3584100 A1 and the DE 10 2006 057509 A1 known, the lifting mechanism for the roof lift in the form of a lifting cylinder arranged centrally along the longitudinal side of the vehicle and the stability mechanism, formed by so-called stability scissors, which are arranged in a rear part of the longitudinal sides of the vehicle and ensure lateral stability of the roof in the extended state, physically In the way. In addition, known pop-up roofs can only be loaded up to about 150 kg due to the construction of the basic sleeping platform, which is not compatible with a load of 4 people.

It is therefore the object of the invention to specify a pop-up roof for a vehicle which, in the second position, offers space for up to 4 people and can carry their load in a stable manner, the pop-up roof also being able to be brought into a position in which additional headroom is obtained in the vehicle will.

This object is achieved with a pop-up roof for vehicles, which is connected to a vehicle body in a state of use, having a roof top shell, a base sleeping plate, an at least partially flexible bellows, the bellows being arranged between the top roof shell and the vehicle body, an extension mechanism for transferring the pop-up roof from a retracted first position into an extended second position, the extension mechanism changing the distance between the upper roof shell (3) and the basic sleeping panel (4) on a pop-up roof front and/or rear (6,7) and the pop-up mechanism on the pop-up roof front and/or or rear side has prestressing elements and stability struts rotatably connected to them, solved in that it has at least one side part which is arranged parallel to the base sleeping plate in the first position and brings it into an extended position in the second position by means of an extension mechanism bar, in which it is arranged coplanarly on a longitudinal side of the base bed board, wherein the extension mechanism has at least one stabilizing element which is at least partially arranged in the base bed board and which holds the at least one side part in the extended position, and that the stability struts in the second position along a Longitudinal axis of the base bed plate are arranged in front of a front and / or behind a rear end of the side panel.

The at least one extendable side part causes a significant widening of the sleeping surface, which extends over the top of the basic sleeping platform and the side parts directly adjoining it. The length of each side part corresponds approximately to the length of the basic sleeping board. In a preferred embodiment, the pop-up roof has two side parts, each side part being located next to a longitudinal axis of the basic sleeping platform in the extended position. In this embodiment, the width of each side part corresponds in particular to approximately half the width of the basic sleeping board, the side parts being mounted in a first manner adjacent to one another on the sleeping board. Preferably there is a mattress of corresponding area on the basic sleeping board, on a top side of this mattress are in the first position all side parts lying on top. Each side part can be connected to the extended position via a pull-out mechanism. This deployment mechanism is fully stowed in the base sleeper panel in the first position. In the extended position, at least a part of the extension mechanism remains in the basic bed board, whereby each side part is held vertically by the extension mechanism on the one hand, and on the other hand it is also stabilized by this in such a way that forces acting on the respective side part, in particular due to weight and movements of people on it, in derived from the basic bed plate and thus distributed along the entire bed surface and thus also introduced into the vehicle body. The part of the pull-out mechanism located within the base bed plate simultaneously creates greater stability for the base bed plate itself, which means that it is able to bear a greater weight without sagging. The flexible bellows is in particular a textile, partially elastic bellows and is designed to be elastic in such a way that in the second position it yields to an extension movement of the side parts. In the extended position, it is tightened and spans a slope between the upper roof shell and the side end of the side panel. This slope creates a comparatively low wind resistance and thus makes the roof less sensitive to wind influences. The elasticity of the bellows, which is preferably present, also allows it to be used with the side parts not extended in a second position, in which the side surfaces of the pop-up roof formed by the bellows are nevertheless stretched. The use of stability struts and the prestressing elements that act on them, which are prestressed in the first position and whose tension energy causes the stability struts and thus the pop-up roof to move up, makes it possible to place the erection and stabilization mechanism clearly outside of a plane each spanned by the longitudinal side the basic bed plate, on which there is a side part in the extended position, and a plumb line dropped on this. This means that the raising mechanism does not get in the way of the side parts and they can be extended. In addition, a person can easily lie on the side part without elements of the raising mechanism getting in the way. If the roof is only pulled out on one side, a displacement of the raising mechanism according to the invention to the ends of the side parts would basically only be necessary on this side. The stability struts are preferably made of a robust material, which means that the positioning mechanism, which is preferably formed by stability struts both in front of and behind the back of the base plate, is comparatively stable and the use of additional lateral stability scissors or similar stabilizing elements can be dispensed with.

In an embodiment of the invention, it is provided that the extension mechanism has, in particular, two stabilizing elements that are offset along the longitudinal axis, and that the at least one stabilizing element is designed as a partially extendable element, with the extendable element being stowed inside the base sleeping panel in the first position and in the extended position is partially extended from this in the direction perpendicular to the longitudinal axis of the basic bed plate.

The extension mechanism thus remains in a first position, which corresponds to a driving condition, within the basic sleeping panel and does not result in any undesirable widening of the pop-up roof. Due to the only partial extension of the extendable element, a not inconsiderable part of it remains within the base sleeping panel. On the one hand, this stabilizes the base plate itself and, on the other hand, there are no horizontal interruptions or connection points that would make it more difficult for the force to be transmitted from the side parts to the base plate or significantly reduce the maximum load. Rather, the extendable element, which is partly connected to the side part and partly contained within the base bed plate, creates a direct power transmission. The use of two extension mechanisms creates double support, in particular on a front and a rear side part area. It is also provided that the extendable element is designed as a multi-part rail, the rail having an immovable fixed part that is firmly connected to the basic sleeping board and on one or two sides of the fixed part pointing in the direction of the front and/or rear end of the side part each have a pull-out part that is movably guided along it, with each pull-out part being stowed inside the base shelf in the first position and being only partially extended out of the base shelf in the extended position.

The fixed part causes a permanent, advantageous stabilization of the base bed plate. In a preferred embodiment with two side parts, each of which can be pulled out on one long side of the base plate, the pull-out parts arranged on the front and rear surfaces of the fixed part remain in the extended position partly within the base plate, partly they serve as a support for the respective side part. This has the great advantage that the entire force acting on the respective side part does not act on the fixed part - extension part connection, but part of the force is already transmitted through the extension part to the base bed plate and thus also to the fixed part initiated. This puts less strain on the connection, making it stable and durable.

In an embodiment of the invention, it is also provided that the at least one pull-out part has a groove along its length, with the fixed part having a projection that engages in the groove along its length, as a result of which the pull-out part is guided along the fixed part (and/or that a length of the fixed part corresponds to a width of the basic sleeping board extending between its longitudinal sides and a length of the pull-out part is longer than half the width of the basic sleeping board, in particular corresponds to the width of the basic sleeping board.

The design of the rail mentioned creates an effective, form-fitting connection between the pull-out part and the fixed part and thus also between the side part and the base plate, with which an effective distribution of the forces acting in particular on the side parts can take place. The design of the pull-out parts on both sides of a fixed part enables a pull-out mechanism that can be used on two sides. This reduces the material and space requirements. Furthermore, in turn, an optimized force distribution is made possible. If the length of the fixed part corresponds to the width of the basic sleeping board, the stabilization of the basic sleeping board is maximized. A length of the pull-out part corresponding to the width of the base plate ensures maximum support of the respective side part along its entire width for maximum stabilization of the same at the same time, since a maximum possible portion of the length of the pull-out part remains within the base plate.

Furthermore, in an embodiment of the invention, it is provided that each side part is connected to at least one extendable element via guide means, in particular via a guide pin rotatably mounted on the extendable element and on the respective side part, so that a lateral extension movement of the respective extendable element results in an extension movement of the corresponding side panel.

In this way, the side part and the extendable element are extended at the same time and no further force has to be exerted on the side part in order to bring it into an extended position. In particular, the side part is thus also held in position horizontally and cannot slip during an extension movement. The guide means are preferably arranged on one of the extending ends of the extendable element or on a lateral end of the side part offset by a few cm inwards, which means that they are protected from direct external influences in the driving state that is usually present, i.e. the first position.

Furthermore, it is provided that the stability struts and the prestressing elements articulated on them are arranged in a first position parallel to the longitudinal side of the basic sleeping board and/or parallel to one transverse side of the basic sleeping board, in particular two stability struts parallel to the longitudinal side and two stability struts parallel to the transverse side, with the Stability struts are each articulated with a first stability strut end at a first fixed pivot point on the vehicle body or the upper roof shell and the prestressing elements are articulated with a first prestressing element end at a second fixed pivot point on the vehicle body.

This minimizes the height of the raising mechanism in the first position. The position of the stability struts on the vehicle body parallel to the transverse side of the basic sleeping platform creates sufficient space on the sides of the pop-up roof for the extension movement of the side parts with a simultaneous stabilizing effect. The preferred embodiment with two stability struts at one end of the basic sleeping board, which are parallel to its longitudinal side, and two stability struts at the other end of the basic sleeping board, which are arranged parallel to its transverse side, creates a particular stability of the lifting mechanism, since the lifting forces are thus in two directions perpendicular to one another works.

In a further embodiment of the invention, it is provided that the stability struts are immovably connected to a second end of the stability strut within a guide, which in the operating state is formed on the upper roof shell or on the vehicle body, in the direction of an erection movement and are movably guided in the direction of a longitudinal side of the upper roof shell.

The mobility of the second end of the stability strut enables the upper roof shell to be lifted as far as possible vertically. In addition, in this way both the first and the second end of the stability strut in the second position can be brought to an outer edge of the vehicle body or the upper roof shell with great advantage. This means that the stability struts in the second position do not prevent the side parts from being pulled out or the person from lying or sitting on them. The guide increases the stability of both the erection movement and the erected roof.

In addition, it is provided in an embodiment of the invention that the guide is designed as a U-profile, in particular having a slot-shaped recess, and that the stability struts are each inside a further U-profile are arranged, wherein in the first position the U-profiles of a stability strut and a guide as well as the associated prestressing element are stacked one inside the other in such a way that the heights of the associated further U-profile and of the prestressing element are contained within a height of a U-profile of the guide .

The guide, designed as a U-profile, with a recess in the form of a slotted hole, enables stable linear guidance along a length of the guide. Vertical movement is prevented by mounting the stability strut in the slot. At the same time, this allows the stability strut to pivot relative to the guide. The further U-profile around the stability strut stabilizes this and thus both the lifting mechanism and the pop-up roof in the second position. The stacked arrangement of the prestressing element, the further U-profile of the stability strut together with the stability strut and the guide, with which the necessary distance between the upper roof shell and the vehicle body resulting from the positioning of the elements mentioned is minimized in the first position and the pop-up roof can be built very flat, i.e hardly needs any additional space at the top.

Provision is also made for the basic sleeping board to be folded up in the second position in the extended position or with the side parts not extended in such a way that it is arranged approximately parallel to the upper roof shell.

With the pop-up roof according to the invention, headroom in the vehicle can thus be generated in a known manner. In the extended position, a comparatively larger space is also created below the upper roof shell or the folded-up basic sleeping platform, which improves the air quality within this space and in the entire vehicle.

In an embodiment of the invention, it is further provided that the at least one side part is rounded at its corners pointing in the direction of the extended position.

In the extended position, the corners and edges of the at least one side part press against the bellows. The rounding of the corners prevents them from damaging the bellows. This applies in particular when the base plate is raised in order to generate standing space inside the vehicle. If this is carried out with the side parts extended, their corners would scrape along the inside of the bellows and damage it.

In addition, it is provided that the height of a side plate and a side mattress arranged, in particular sewn on, corresponds to a sum of the height of a basic mattress arranged, in particular sewn on, on the basic sleeping plate plus the distance between a top side of an extendable element and a top side of the basic sleeping plate or that the Basic sleeping plate can be brought in the extended position by a distance corresponding to the difference between the first-mentioned height and the sum mentioned in the direction of the upper roof shell.

In the former case, the side part is pulled minimally beyond the base plate by the pull-out mechanism in conjunction with the guide means, and the guide means offer no vertical resistance, so that the side plate slides down onto the extendable element. The height requirement mentioned results in a uniform height of the sleeping area created. Instead of a gravity-driven sliding down of the side parts onto the extendable element, an embodiment of the invention also provides a lowering mechanism that is integrated into the guide device or is separately assigned, with which lowering can take place in a controlled manner and with little stress. It is also provided here that said mechanism is designed in such a way that it enables the side plate to be moved to a height of the first position. This means that there is no need to lift the side panel to assemble the pop-up roof or move it into the first position.

In the second case, the side part does not slide down onto the extendable element, instead it is raised. When lifted by the stated height, an even sleeping surface is again generated.

In a development of the invention, it is also provided that the prestressing elements are designed as gas pressure springs, in particular that the gas pressure springs have an additional spring.

This enables an easy-to-use and stable design of the prestressing elements. The additional spring enables an additional input of energy when relaxing during an opening movement and thus the improved triggering of a relaxation of the gas pressure springs and thus an opening of the pop-up roof.

In addition, it is also provided that a fastening mechanism, in particular a fastening bolt, is arranged on each side part, which in the operating state in the extended position connects the side parts to the vehicle body.

In this way, the pop-up roof remains stable in an extended position against a tipping movement when there is a load on one side. In this way, forces are better dissipated in the vehicle body.

1 shows a pop-up roof 1 according to the invention in the second position. The pop-up roof 1 is attached to a vehicle body 2 of a vehicle. A termination at the top is formed by a top shell 3 of the roof. A position of the pop-up roof 1 is shown, in which two side parts 10 that can be brought into an extended position are arranged on a basic sleeping platform 4 or on a basic mattress 27 connected to it, not shown here, so that the width of the pop-up roof 1 that is set up does not exceed one width of the vehicle body 2 goes out. This corresponds to a position of the base sleeping panel 4 and the side parts 10 in the first position, in which the upper roof shell 3 is lowered and covering it. Located along a longitudinal axis X of the basic sleeping platform 4 in front of it is an entrance 29 that is accessible from inside the vehicle when in use. A pop-up mechanism is the pop-up roof 1 moving from the first position suitable for driving to the second position. According to the invention, this is arranged in front of a front side part end 13 and behind a rear side part end 14 . With an erecting movement by the erecting mechanism, an erecting movement of the upper roof shell 3 takes place on a pop-up roof front side 6 and on a pop-up roof rear side 7 . In the embodiment shown, the front side 6 of the pop-up roof is higher than the rear side 6 of the pop-up roof in comparison to the vehicle body 2, which corresponds to the typical set-up position of pop-up roofs. Due to the fact that the back of the pop-up roof 7 is also raised, the space inside the pop-up roof 1 is increased in the second position, so that a person can also lie down with their head pointing towards the back of the pop-up roof 7 without touching the upper roof shell 3 or the pop-up roof 1 on its side faces to the outside, to abut bellows 5, not shown here. According to the invention, however, is also an embodiment in which the relative heights of the front and rear of the pop-up roof 6.7 are reversed. Also according to the invention is an embodiment, not shown here, in which the installation heights of the front and rear of the pop-up roof 6, 7 are the same. The erection mechanism has stability struts 9 and prestressing elements 8 rotatably connected to them. The stability struts 9 and prestressing elements 8 are arranged on the front side 6 of the pop-up roof in a first position of the pop-up roof 1 (not shown here) parallel to the longitudinal sides 11 of the base sleeping panel 4 on the vehicle body 2, in particular outside of the bellows 5, which extends in a known manner in the first position folded or rolled up between the upper roof shell 3 and the vehicle body 2 is located. The stability struts 9 and pretensioning elements 8 on the rear side 7 of the pop-up roof are arranged parallel to transverse sides 20 of the basic sleeping plate 4 on the rear side 7 of the pop-up roof on the vehicle body 2 according to the embodiment shown in the first position mentioned. A vertical extension of the pop-up mechanism in the first position is thus minimized and the pop-up roof 1 according to the invention does not require any significant increase in comparison to known pop-up roofs. To bring it into the second position, the raising mechanism is actuated, which causes the prestressing elements 8 to relax, increasing their length and bringing the stability struts 9 into an almost vertical position. In the embodiment shown, a width of each side part 10 corresponds approximately to half of the width 18 of the base sleeping panel 4. This maximizes the width of a sleeping surface spanned by the base sleeping panel 4 and the side parts 10 when it is in the extended position.

In 2 is that in the in 1 shown embodiment of the pop-up roof according to the invention 1 shown in an extended position. The two side parts 10 are arranged along the longitudinal sides 11 of the basic sleeping board 4 next to it. Depending on the heights of the base bed plate 4 and side part 10 and the design of an extension mechanism or the associated stabilizing element 12 (not visible here) and the sen arrangement in the base bed plate 4, an upper side of a side part 10 is offset plane-parallel to an upper side of the base bed plate 4 is arranged. This difference in height is compensated for by the different heights of the mattresses arranged on the base sleeping platform 4 and the side part 10, with the result that a flat sleeping surface is created. The in particular textile bellows 5, the side surface of which in a second position, in which the side parts 10 are not extended, runs approximately perpendicularly between the upper roof shell 3 and the vehicle body 2, is sufficiently elastic to allow the side parts 10 to move outwards along it. The side surface now spanned by bellows 5 in an extended position has a significantly smaller angle to the surface of side part 10 or the upper side of vehicle body 2 . This angled side surface offers less resistance to winds hitting it, in that the flow is partly guided over the pop-up roof 1.

3 shows a side view of an embodiment of the pop-up roof 1 according to the invention in a second position. In the case shown, the side parts 10 are not extended and are therefore arranged on the basic sleeping platform 4 or the basic mattress 27 sewn onto this. The bellows 5 extends between the upper roof shell 3 and an underside of the pop-up roof 1, so that it closes off the pop-up roof 1 on all sides. Side mattresses 26 are arranged on each of the side parts 10, with the base and side mattresses 27, 26 having different heights in order to ensure a flat sleeping surface in the extended position. According to another embodiment of the invention, not shown here, the base and side mattresses 27 , 26 can have approximately the same height and the side part 10 can have a correspondingly lower height than the base sleeping board 4 .

In a first position or in the illustrated non-extended state of the side parts 10 , an extension mechanism is stowed inside the base sleeping panel 4 , which has a stabilizing element 12 . This extension mechanism brings the side parts 10 into an extended position, not shown here. The stabilizing element 12 is in each case holding a side part 10 in the extended position. The preferred embodiment shown has two stabilizing elements 12 which are offset along the longitudinal side 11 of the basic sleeping board 4 . The stabilizing element 12 or the extension mechanism is designed as a multi-part rail 15 which can be partially extended out of the base plate 4 in a direction parallel to the transverse side 20 thereof. In this case, the rail 15 has an immovable fixed part 15a, which remains completely within the base sleeping plate 4 even in the extended position. An extension part 15b is arranged on the fixed part 15a on a side pointing in the direction of a pop-up roof front side 6 and on a side pointing in the direction of a pop-up roof rear side 7, which is linearly movable along the fixed part 15a. In the extended position, the two pull-out parts 15b arranged on a fixed part 15a are each partially pulled out of this in an opposing direction parallel to the transverse side 20 of the base sleeping plate 4 . Preferably, the two pull-out parts 15b and the fixed part 15a each have a length that corresponds to the width 20 of the base sleeping panel 4 . If the respective pull-out part 15a is extended, it provides maximum support and stabilization for the side part 10 lying on it in this extended position along its entire width. At the same time, a maximum possible length remains, namely just about half the width 20 of the basic sleeping board 4, for improved force transmission and stabilization of the rail 15 and the overlying side part 10 within the basic sleeping board 4. In the embodiment shown, there are at an outer end of the pull-out part 15b Guide means 19 rotatably attached to the extensible member 15b and to an outer side of the side member 10 via a guide attachment 30, respectively. These are an extension movement of the extension part 15b on the side part 10 forward, so that the side part 10 is extended according to the extension part 15b. The guide means 19 are preferably designed in such a way that they do not block the side part 10 from sliding down from the basic mattress 27 onto the pull-out part 15b. The pull-out mechanism and its guide means 19 are designed according to the invention in such a way that in the extended position they move the respective side plate 10 minimally over the width of the basic mattress 27, so that it is possible to slide down from it and at the same time there is no interruption in the sleeping area formed due to a distance between the basic mattress 27 and side mattress 26 results.

In 4 a section of a lower area of a pop-up roof 1 according to the invention is shown in a first position or in a second position with side parts 10 not extended. In the embodiment shown, the extension mechanism is incorporated into the basic sleeping board 4, its height extension is less than a height H5 of the basic sleeping board 4. However, an extending mechanism that is not limited by the basic sleeping board 4 in the direction of an upper side is also in accordance with the invention. In particular, an extension mechanism is according to the invention, as a result of which the side part 10 resting on the extendable element in the extended position is resting at the level of the top side of the base bed plate 4; in this case, a distance A between a top side of the extendable element, or the pull-out part 15b and the top of the base bed plate 4 equal to zero. The difference in height between the top of the base mattress 27 and the side mattress 26, which is due to the different heights H3 of the side part 10 and the side mattress 27 lying on it and the height H4 of the base mattress 27 or the sum S of the distance A between the top of the pull-out mechanism and the The upper side of the base sleeping platform 4 and the height H4 of the base mattress 27 can be selected to be zero, in particular through the corresponding height of the side part 10 or the side mattress. In the embodiment shown, the fixed part 15a of the rail 15 has a projection 17 on the sides on which an extension part 15b is adjacent, which engages positively in a groove 16, which is formed along the length of the adjacent extension part 15b. the pull-out part 15b remains movable along the fixed part 15a. In the embodiment shown, the guide means 19 are offset a few centimeters inwards so that they are not visible from the outside. A narrow slit within a lateral end area of the basic mattress 27 enables the guide means 19 to be guided through to the end of the extension movement. The even sleeping surface is not disturbed by this.

In the 5a is a positioning mechanism in the 1 . and 2 shown, pop-up roof according to the invention in the second position, the 5b Figure 12 shows the same embodiment of this mechanism in the first position. The stability strut 9 of the raising mechanism is arranged almost vertically in the second position, approximately at an angle of 80-85 degrees, on the upper roof shell 3 or on the vehicle body 2 . In the illustrated embodiment, the stability strut 9 is rotatably arranged on the vehicle body 2 at a first end 9a of the stability strut at a first fixed pivot point 21 . At a second stability strut end 9b, the stability strut 9 is linearly guided in a guide 23, for which purpose it has a slot 31, with the stability strut 9 being rotatably mounted relative to the guide 23. Within the length of the stability strut 9, the latter is rotatably connected at a pivot point to a pretensioning element 8, in particular in the form of a gas pressure spring. In the second position (see 5a) the prestressing element 8 is also arranged at an angle to the vehicle body 2 . In the first position (see 5b) Both the stability strut 9 and the prestressing element 8 are arranged almost parallel to the upper side of the vehicle body 2 or to the longitudinal axis X of the basic bed plate 4, not shown here. The setting-up mechanism can be moved from the first to the second position as a result of an energy pulse to be entered by a user. The introduction of the energy pulse causes the prestressing element 8 to expand, in particular as a result of its spring tension. This is only possible in one direction along the vehicle body 2 since the prestressing element 8 is connected to it at one end at a second fixed pivot point 22 . The expansion of the prestressing element 8 leads to a coupled tilting and axial movement of the stability strut 9 relative to the roof top shell, the prestressing element 8 being rotatably connected to the stability strut 9 at another end, as a result of which the roof top shell 3 is lifted. Due to this coupled movement, the upper roof shell 3 moves only slightly along the longitudinal axis X during the erecting movement. This makes it possible to arrange the elevating mechanism according to the invention at the ends of the elevating roof 1, i.e. in the direction of the longitudinal axis X in front of a front side part end 13 and behind a rear side part end 14, and thus to create space for an extension movement of the side parts 10 or for people to move allow you to move around inside the pop-up roof 1 without any obstacles. The guide 23 is in the form of a U-profile with a slot 31 formed on at least one side. The stability strut 9 is also arranged within a further U-profile 24, with the exception of the front and rear stability strut ends 9a, 9b, with an opening in the further U-profile 24 pointing in the direction of the prestressing element 8, with the latter being within the further U-profile 24 can be articulated on the stability strut 9 . The size of the two U-profiles is chosen so that they can be stacked one inside the other in the first position, a height H1 of the U-profile is therefore higher than a height H2 of another U-profile. The pretensioning element 8 can also be stowed in the first position as far as possible in the opening of the further U-profile. In this way, the height of the raising mechanism in the folded first position is minimized to the height H1 of the U-profile and the stability strut 9 is mechanically supported by the further U-profile 24 at the same time.

6 shows a top view of a pop-up roof 1 according to the invention in a second position. Rounded corners 25 can be clearly seen on the outwardly pointing sides of the side parts 10 . In the illustrated non-extended state, the side parts 10 are arranged on the base sleeping platform 4 . The entrance 29, which is located in a front area of the pop-up roof 1, in the direction of the longitudinal axis X in front of the basic sleeping platform 4, is also clearly visible 1 can be secured in a first position against accidental setting up. In this area is bilateral In addition, a fastening mechanism 28 is arranged on the vehicle body 2, which connects the two side parts 10 to it in the extended position and thus prevents a tilting movement of the entire pop-up roof 1 by diverting acting leverage forces into the vehicle body 2.

The invention enables a widening of a slack area within a pop-up roof of a car. The height of the car roof is hardly increased in a first position, which corresponds to a driving condition, so that the pop-up roof according to the invention remains practical. The invention combines a modified raising mechanism that is moved to the rear and front end of the pop-up roof with a stabilization and pull-out capability of the sleeping surface by means of a special pull-out and stabilizing mechanism that is partially integrated within the base sleeping plate, which enables a widened, stable sleeping surface.
