Description

SUPPORT FOR A FUNCTIONAL ELEMENT IN A PAIR OF RAILS WITHIN A

PASSENGER COMPARTMENT OF A MOTOR VEHICLE

TECHNICAL FIELD

The invention relates to a support for a functional element in the form of a container, an armrest or the like in a pair of rails within a passenger compartment of a motor vehicle.

In particular, the invention relates to such a support in a passenger vehicle.

BACKGROUND

Motor vehicles are known, in particular passenger vehicles, in the case of which a pair of rails for accommodating a container, an armrest or the like, is arranged in the passenger compartment. The rails, which are arranged parallel to one another, are in particular arranged between the driver's seat and the front passenger's seat, so that the functional element can be accessed from both seats. After overriding a frictional connection with respect to the two rails, the functional element can be displaced forwards or backwards because of the guide by means of the two rails in the passenger compartment, so that it can be displaced into an ergonomically favorable position to the vehicle passengers of the front seats or so that it can be displaced backwards, from the area between the front seats. In addition, provision can be made for means for locking functional element and rails, so as to be able to position the functional element so as not to be capable of being displaced with respect to the pair of rails. After unlocking these means, the displacement of the functional element is then possible.

The support for a functional element in the form of a container, an armrest or the like in a pair of rails within a passenger compartment of a motor vehicle is known from EP 2 093 107 Al. The two rails of the pair of rails encompass guide grooves on sides, which face one another. Axially displaceable, bolt-like guide elements are supported in a housing of the functional element, on the side thereof, which faces the respective rail.

The respective bolt encompasses a projection, which faces the rail assigned to the bolt.

The respective guide groove has a cross section, which expands from the groove base.

The respective projection encompasses a cross section, which expands accordingly towards the housing of the functional element. A spring acts on the guide element and pretensions the projection thereof against the guide groove. The guide element can be moved from the position, which causes the frictional connection, with respect to the guide groove by means of an actuator, which is supported in the housing, opposite to the force of a spring.

In the case of this known support, provision is made in the front area of the functional element, on the two sides thereof, for axially displaceable guide elements, which can be brought into frictional contact with the guide grooves of the rails, In the rear area of the functional element, two axially displaceable guide elements are likewise arranged on both sides of the functional element, which can be brought into frictional connection with the guide grooves of the two rails as well as into a locked position with regard to the rails, in that extension pins of the guide elements can be inserted into holes in the area of the guide grooves of the rails. The actuation of the guide elements arranged in the front is thereby carried out in a different manner than that of the guide elements, which are arranged in the rear. Control levers for transferring the movement of the manually actuatable actuator to the guide elements are therefore designed differently.

In the case of both alternatives, the control levers encompass a lever section, which is provided with a ball-shaped free end, wherein this lever section engages with a recess in the guide element with a small play in actuating direction of the guide element.

A pressure spring, which pretensions the guide elements of the pair in the direction of the guide grooves of the rails, is effective between a cooperating pair of guide elements, thus the pair, which is formed by means at the two front guide elements or by means of the two rear guide elements, respectively.

INVENTION

It is the object of the invention to provide for a support for a functional part in the form of a container, an armrest or the like in a pair of rails within a passenger compartment of a motor vehicle, which ensures that, in response to a structurally simple design of the cooperating parts, the control levers can transfer the movement to the guide elements and that it is furthermore not necessary that provision be made between guide elements of the same pair of guides for a spring, which engages directly at that location, whereby this area can also be designed in a structurally simple and assembly-friendly manner.

To solve this problem, the invention proposes a support according to the features of patent claim 1.

It is essential for this support that the respective guide element encompasses a section, which is embodied as gear rod and which cooperates with a gear wheel section of a control lever, which is pivotably supported in the housing of the guide element, wherein the control lever can be pivoted by means of the actuator, which is supported in the housing. When actuating the actuator supported in the housing, the control lever is thus pivoted and acts like a drive with the gear wheel section thereof with the section of the assigned guide element, which is embodied as a gear rod. The pivoting of the control ever is thus transferred into an axial movement of the guide element in a permanently coupled manner. This allows the positioning of the spring at any location in a frictional connection between actuator and axiarly displaceable guide element. The movements of the two control levers, which cooperate with the two front or with the two rear guide elements, are in particular permanently coupled.

Seen from this perspective, a first advantageous design provides for the spring, which acts on the guide element, to be a control spring, which engages with two control levers, which are assigned to different sides of the housing of the functional element. A second advantageous design provides for the spring, which acts on the guide element, to act on the actuator, contrary to the direction of movement of the actuator, for moving the guide element out of the contact position in the guide groove, wherein the actuator is positively connected to two control levers, which are arranged at different sides of the housing of the functional element. In this case, it is thus not necessary for the spring to engage with control levers.

It is considered to be particularly advantageous when the control levers of the functional element are embodied as non-variable parts. This leads to a considerable reduction of costs, in particular of tool costs.

Seen from the perspective of embodying the control levers as non-variable parts, it is considered to be advantageous when the respective control lever encompasses the gear wheel section, a lever section, which can be acted upon by means of the actuator for the guide elements arranged in the front area of the functional element, a lever section, which can be acted upon by means of the actuator for the guide elements arranged in the rear area of the functional element, as well as a lever section comprising an accommodation for connecting a control spring. In the case of such an embodiment of the respective control lever as non-variable part, certain lever sections are used in response to the arrangement of the control lever in the front area of the functional element, but not all of the lever sections, and certain, partially other lever sections are used in response to the use of the control lever in the rear area of the functional element, but not all of the lever sections. In each application, the gear wheel section, which cooperates with the section of the assigned guide element, which is embodied as gear rod, is effective.

The displacement axis of the respective guide element, which cooperates with the guide groove, and the position of the guide groove in the rail can be different. The displacement axis of the guide element can thus be aranged horizontally and the upper arm extending from the groove base of the respective guide groove as well as the lower arm extending from the groove base can be arranged diagonally to the horizontal. This implies that the projection of the bolt-like guide element in its upper and lower area is accordingly also arranged diagonally to the horizontal. Due to this conical shape of the projection and the angle, which differs to the horizontal, forces in axial direction of the bolt-like guide element can be introduced into the latter due to the dead weight of the functional element in the form of the container, the armrest or the like, by loading the container, by supporting a passenger of the vehicle on the container or the armrest, respectively. These forces are effective opposite to the force of the spring, which presses the guide element into the guide groove.

To avoid that the frictional connection between rails and guide elements is overridden as a result or that the unlocking of the system takes place unintentionally by introducing a force in axial direction of the respective guide element opposite to the force of the spring, it is necessary to reinforce it To avoid this disadvantage, it is proposed for the lower arm of the guide groove, which extends from the groove base of the respective guide groove, to be arranged horizontally and for the displacement axis of the guide element for this guide groove to be arranged diagonally to the horizontal. By horizontally supporting the lower arm of the guide groove, a force component is not introduced into the axially displaceable, bolt-like guide element in axial direction thereof in response to a vertical load by the dead weight of the container, in particular of the loading space container and/or of the armrest, further the weight of stowed objects and the forces introduced into the armrest by supporting a person, whereby the system is self-locking. The frictional forces between guide element and guide groove are not reduced in terms of the displaceability of the functional element in the pair of rails and when the guide element additionally serves to lock with the rail, it is impossible for an unlocking to take place by creating a force component in axial direction of the bolt-like guide element. With this design, the required spring forces for the actuation of the bolt-like guide elements or for the unlocking, respectively, as well as forces of springs, which can be provided within the guide elements for the purpose of a tolerance compensation, can be reduced. The required application of force for actuating the guide elements is thus reduced. This leads to a comfort improvement for the operation of the adjustable armrest or of the adjustable container1 respectively, in particular loading space container.

The guide groove is designed so as to be particularly simple with reference to structure and the self-locking system can be realized in a simple manner, when the guide groove encompasses a trapezoidal cross section and the projection of the guide element encompasses a section, the cross section of which is designed in a correspondingly trapezoidal manner. Under the impact of the springs, the respective guide element, with its diverging areas of the section, which is designed in a trapezoidal manner, comes to rest against the diverging areas of the guide groove.

A locking of functional element and rail can be realized in a particularly simple structural and functional manner, when at least one of the guide elements, in particular one guide element on each side of the housing of the functional element, encompasses an extension pin, which extends beyond the projection in the area of its end, which faces the assigned guide groove, for inserting into a hole in the base of the guide groove. The extension pin can be inserted into the hole of the rail with a slight play in displacement direction of the functional element, and thus fixes the functional element in displacement direction of the rail with respect to the latter.

The projection and the extension pin in particular form one component.

The guide groove of the guide rail thus has in particular a basic conical shape. The basic conical shape, however, is embodied such that the lower arm in installation position is arranged horizontally. The imaginary center line of the symmetrical basic conical shape of the guide groove in the guide rail thus runs at a defined angle to the horizontal plane.

The guide elements encompass in particular conical ends, which correspond to the basic conical shape of the guide groove in the rail. The conical ends of the guide elements glide along this conical contour in the groove of the rail. For a smooth displacement of the functional element, provision is to thus be made for a contact surface between guide element and groove of the rail, which is as small as possible.

This is obtained by means of the conical contour of the ends of the guide elements.

The effective direction for disengaging or unlocking the functional elements, respectively, for displacing the functional element runs along the imaginary center line of the basic conical shape of the groove in the respective guide rail. The effective direction for the disengagement or unlocking1 respectively, is thus arranged diagonally to the horizontal axis.

For the purpose of tolerance compensation, provision is made in the case of the system for a pressure spring to be arranged within the guide element, which is embodied in two parts. In particular, the respective guide element encompasses a first part, which encompasses the projection, and a second part, which is supported so as to be axially displaceable in the first part as well as so as to be displaceable in the housing of the guide element. The two parts are connected to one another by means of a latching connection with axial play and a pressure spring is effective between the two parts. In particular, the two parts are inserted into one another and form a cavity, wherein the pressure spring is arranged within the cavity. By introducing the spring into the guide element, assembly is simplified, because the spring is assembled with the guide element in a pre-operation and can be inserted into the housing of the functional element as a complete unit.

For the support1 provision is thus made for the axial displacement of the respective guide element opposite to the force of the spring for the respective guide element to encompass a section, which is embodied as gear rod and which cooperates with a gear wheel section of a control lever, which is pivotably supported in the housing of the functional element, wherein the control lever can be pivoted by means of the actuator, which is supported in the housing. The guide element is moved inwardly in a straight line via the gear rod through the gear wheel section and the guide element is transferred from its disengaged position into the engaged position or from the locked position into the unlocked position, respectively. This mechanics for moving the guide element can be illustrated in a particularly simple manner with regard to its structure due to the mentioned design.

The support is characterized by a reduction of tool costs by using a maximum number of non-variable parts. The components involving the support can be assembled easily, thus reducing the assembly time. The mechanism for actuating the guide elements is embodied in a robust manner.

DETAILED DESCRIPTION

With reference to both exemplary embodiments, the support for a functional element I embodied as a loading space container in a pair of rails, which is formed by two rails 2, in an interior of a passenger vehicle is described in the figures. Extending from a front dashboard of the passenger vehicle, the pair of rails comprising the two rails 2, which are arranged parallel at a distance to one another, is arranged between the driver's seat and the front passenger's seat and extends up to the second row of seats, which is arranged behind this first row of seats of the vehicle. The pair of rails serves to displaceably accommodate the functional element I in rongitudinal extension of the two rails 2, with the possibility of locking the functional element I with regard to the pair of rails. The displacement direction is hereby horizontal, parallel to the floor of the vehicle interior. In the area of each rail 2, the functional element 1 is guided in the front and the rear in the rail and can be connected thereto by means of a frictional connection, wherein provision is made in the area of the front guide, on each side of the functional element 1, for an additional lock for the functional element 1 with regard to the respective rail 2.

On sides facing one another, the two rails 2 in each case encompass a guide groove 3.

Axially displaceable, bolt-like guide elements 5 comprising projections 6, which face this rail 2, are supported in a housing 4 of the functional element 1, which forms the actual container, in the front and on the rear side thereof, which faces the respective rail 2.

The respective guide groove 3 encompasses a cross section, which expands from the groove base 7. The respective projection 6 encompasses a cross section, which expands accordingly towards the housing 4 of the functional element 1. Concretely, the guide groove 3 encompasses a trapezoidal cross section and the projection 6 of the guide element 5 encompasses a section, which is designed in a trapezoidal manner, corresponding to the cross section. On each side of the housing 4, in the front area of the housing 4, the guide element 5 located there is provided with an expansion pin 8, which projects beyond the projection 6, in the area of its end, which faces the assigned guide groove 3. The projection 6 and the extension pin 8 form one component. In the area of the groove base 7, distributed across the length of the guide groove 3, the respective guide groove 3 encompasses diverse holes 9. In the case of an oriented arrangement of the functional element 1 with regard to the rail 2, in which the extension pin 8 is aligned with the hole 9, the extension pin 8 can be inserted into the hole under the impact of spring force, whereby the functional element 1 is locked with regard to the rail 2.

This spring, which acts on the guide element 3 and which pretensions the projection 6 thereof against the guide groove 3 in the area of its expanding cross section, is identified with reference numeral I ft By means of an actuator 13! which is supported in the housing 4 and which can be pivoted there about an axis 25, the two guide elements 5, which are arranged in the front area of the functional element 1 and which encompass the extension pins 8, can be transferred opposite to the force of the spring 10 from their locked position according to Fig. 2 into the disengaged position thereof, thus unlocked position according to Fig. 3, in which the extension pins 8 are moved out of the holes 9 in the two rails 2 and in which the projections 6 of the guide elements 5, which face the two rails 2, are furthermore completely moved into the housing 4. In the rear area of the functional element 1, however, only guide elements 5, which are only provided with the projections 6 and which thus do not encompass any extension pins 8, are arranged on both sides of the housing 4 By means of a rear actuator 13, these two rear guide elements 5 can be transferred opposite to the force of a spring 10, which acts on the two rear guide elements 5, from the frictional connection into the non-frictional connection described for the front guide elements 5 with regard to the rail 2, in which they are completely moved into the housing 4. With regard to the kinematics of the rear guide elements 5, reference is made in this regard to the below description of the kinematics of the front guide elements 5.

The respective guide elementS thus encompasses a first pal 14, which is displaceably supported in the housing 4 of the functional element 1 and which encompasses the projection 6, and a second part 15, which is supported in the part 14 and which is displaceably supported in the housing 4 of the functional element 1. An extruded web 26 of the housing 4, which consists of plastic, which is arranged diagonally to the displacement direction of the functional element 1, hereby supports the guide element 5. For compensating tolerances, the two parts 14 and 15 are connected by means of a latching connection 16 with axial play and a pressure spring 17 is effective between the -10 -two parts 14 and 15. Inserted into one another, the two parts 14 and 15 form a cavity 18, in which the pressure spring 17 is arranged.

The respective guide element 5, in particular the second part 15 thereof1 encompasses a section 19, which is embodied as gear rod and which cooperates with a gear wheel section 20 of a control lever 21, which is supported in the housing 4 of the functional element I so as to be capable of being pivoted about an axis 22. The control lever 21, which is axially fixed by means of a fixing pin 27, encompasses further sections 23, 24 and 2T To actuate each front pair of guide elements 5, provision is thus made for two control levers 21. likewise, provision is made for two control levers for actuating the rear pair of guide elements 5. Each front or rear pair of control levers, respectively, can be pivoted opposite the force of the spring 10, in terms of the disengagement movement of the respective guide element 5.

The control levers 21, which are used in the case of the functional element 1, are identical, thus embodied as non-variable parts. Depending on whether the control lever is arranged in the front area of the functional element I or in the rear area thereof in the housing 4, different areas of the control lever are used. When arranging the control levers 21 in the front area of the functional element 1, such as illustrated in Fig. 1, for example, the gear wheel section 20 cogs with the section 19 of the respective guide element 5, which is embodied as gear rod, and the spring 10, which is embodied as control spring, is connected in the area of the free ends of the sections 23 of the two control levers 21. The two sections 23 are arranged so as to face one another The sections 24 of the two control levers 21 are arranged so as to face away from one another. In the locked position of the two guide elements 5, they encompass an upper surface, which is arranged so as to be substantially horizontal and which are contacted in response to the actuation of the actuator 13, thus the pivoting of the actuator 13 about the axis 25, whereby the one control lever 21 is moved in clockwise direction and the other control lever 21 is moved in counter-clockwise direction and hereby tension the spring 10. The further sections 27 of the two control levers 21, which are arranged in the front, are not used in the case of the control levers 21, which are arranged in the front.

The gear wheel sections 20 of the two control levers 21, which are arranged in the rear area of the functional element 1, for actuating the two rear guide elements 5, which serve the frictional connection with the rails 2, are likewise engaged with the section 19 of the two guide elements 5, which is embodied as gear rod, The sections 22 and 23 of the respective control lever 21 are not used, As can be seen from the illustration of Fig. -11 -for the rear area of the functional element 1, the actuator 13 can be displaced in a straight line in the housing 4 of the functional element 1, concretely for moving the two guide elements 5 into the housing 4 opposite to the force of the spring 101 wherein this spring 10 is supported on the actuator 13 and on the housing 4. A cylindrical projection 28, the axis of which is parallel to the pivot axis of the two control levers 21 and which engages with overlapping U-shaped recesses 29 of the sections 27 of the control levers 21, forms a component of the actuator 13 arranged in the lower area thereof.

When pulling the actuator 13 upwards opposite to the force of the spring 101 the one control lever 21 is pivoted in clockwise direction and the other control lever 21 is pivoted opposite the clockwise direction due to the positive connection of the projection 28 with the sections 27 of the two control levers 21, so that the two guide elements 5 are moved towards one another. When the actuator 21 is released again, the spring 10 effects the opposite movement of the control levers 21 and of the guide elements 5, so that they are transferred again into their position, which is extended out of the housing 4, and thus into the position, which is retracted into the guide grooves.

In the case of the exemplary embodiment according to Figures 1 to 8, arms lower arm 11 and upper arm 30 -which extend from the groove base 7 of the respective guide groove 3, are arranged diagonally to the horizontal and the displacement axis 12 of the respective guide element 5, which is assigned to this guide groove 3, is arranged horizontally.

The exemplary embodiment according to Figures 9 and 10 differs from that according to Figures ito 8 in that the lower arm 11 of the guide groove 3, which extends from the groove base 7 of the respective guide groove 3, is arranged horizontally and that the displacement axis 12 of the guide element 5, which is assigned to this guide groove 3, is arranged correspondingly diagonally to the horizontal.-To avoid repetitions, reference is made to the detailed embodiments relating to the other exemplary embodiments with regard to the other details of this exemplary embodiment.

The described support for the functional element 1 in the pair of rails in the passenger vehicle represents a robust system for the rails 2 and guide elements 5, which glide therein, for individually adjusting or positioning, respectively, the functional element 1 along the rails 2. In particular the horizontal position of the respective lower arm 11 of the guide groove 3 according to the second exemplary embodiment ensures that a force component is not introduced in effective direction for disengaging or unlocking, respectively, the guide elements 5 with regard to the rail 2 in response to the -12 -introduction of a vertical load into the rail 2 by means of the functional eren-,ent 1 The system is thus self-locking. The required spring forces for the actuation of the unlocking at the control lever 21 as well as the spring forces within the guide elements 5 for the tolerance compensation by means of the additional pressure spring 17 can thus be reduced through this. The required expenditure of force for actuating the unlocking mechanism is reduced through this. This leads to a comfort improvement for the operation of the adjustable functional element 1. To unlock the guide elements 5 or to override the frictional connection of guide elements 5 and rails 2, respectively, the guide element 1 is seized at the front and rear in the area of recessed grips of the actuators 13 and the functional element 1 can then be displaced in rongitudinal direction of the rails 2 or can be removed therefrom, respectively.

The illustrated embodiments only show possible embodiments of the invention, for which further numerous alternatives are possible and Jie within the scope of the invention The exemplary embodiments, which are shown in an exemplary manner, are in no way to be interpreted as being limiting with regard to the scope, the applicability or the configuration possibilities of the invention. The instant description only shows a possible implementation of an exemplary embodiment according to the invention to the person of skill in the art. The most diverse modifications can be made to the function and arrangement of described elements, without hereby leaving the scope of protection or the equivalents thereof, which are defined by means of the following patent claims.
