Description

The invention relates to a seat assembly for a vehicle with an adjustable footrest.

A seat assembly for a motor vehicle with a vehicle seat and an adjustable footrest, which is arranged along a seat longitudinal axis in front of the vehicle seat, for example, from the EP 1 892 181 A2 out. This document teaches a height-adjustable footrest having a plate-shaped segment for forming a shelf for the feet of a seat occupant. The plate-shaped segment is by means of a drive mechanism of the seat assembly force-actuated upward adjustable by the segment is moved, for example, along a guide slot. In one embodiment, a footrest of the EP 1 892 181 A2 two articulated segments on. While one of the segments is supported on a body part, the other segment is drivable via the drive mechanism, so that the two articulated segments can be displaced relative to each other. On the one hand, a planar storage area in front of the vehicle seat can be formed via the two segments on the one hand in an initial position of the footrest and, on the other hand, in a storage position of the footrest an inclined and elevated storage surface, in which the two segments are angled to each other and thus define a triangular shape in cross section. Seat assemblies with adjustable and separate from the vehicle seat footrest, as shown in particular from EP 1 892 181 A2 are known, regularly claim comparatively much space. Furthermore, the adaptability of the footrest is limited to individual wishes of the seat occupant, in particular with regard to the setting of different storage positions and thus inclinations and heights defined by the footrest storage space for the feet of a seat occupant.

The object of the invention is therefore to overcome or at least reduce the abovementioned disadvantages and to provide a seat assembly improved in this respect.

This object is achieved with a seat assembly according to claim 1.

Hereinafter, a seat assembly for a vehicle, in particular a motor vehicle, proposed in addition to a vehicle seat at least one (separate from the vehicle seat) adjustable footrest, which is arranged along a seat longitudinal axis in front of the vehicle seat. Here, the footrest on at least three articulated segments connected to each other, which are displaced relative to each other. Furthermore, a drive mechanism of the seat assembly is provided, by means of which at least one (drive) segment can be driven by external force actuation along the seat longitudinal axis. About the drive mechanism is the footrest between a starting position in which the segments in front of the vehicle seat form a substantially flat shelf for the feet of a seat occupant of the vehicle seat, and at least one storage position in which the segments inclined relative to the shelf in the starting position and / or make increased storage space, adjustable. Of the at least three articulated segments at least one middle segment is hingedly connected to a front and a rear segment, wherein for the formation of the shelf in the at least one storage position of the footrest, the at least one middle segment with respect to the starting position with a perpendicular to the longitudinal axis Directional component is adjustable.

In the proposed seat assembly thus at least one middle segment is articulated on both sides along the longitudinal axis of the seat on each a further segment and with a directional component perpendicular to the seat longitudinal axis up and down displaced. In this way, for example, in particular an elevated level storage surface over this at least one central segment can be defined, as well as a finely graduated adjustment of a slope of a shelf of the footrest in a different position from the starting position storage position of the footrest possible. For example, one from the EP 1 892 181 A2 known embodiment only a footrest with only two segments and thus without a middle segment before. One of the two segments is driven by a drive mechanism. A comparatively tapered contour of the raised footrest in a storage position is thus always the result. Also, in this embodiment of the prior art no planar and thus substantially horizontally extending shelf surface can be defined. A flat storage surface can be defined only in the starting position of the footrest, in which the two articulated segments are arranged substantially aligned with each other one behind the other along the seat longitudinal axis and oriented at an angle of 180 ° to each other.

With the proposed solution, in contrast, a segmented footrest is provided, which is provided in the intended installed state of the seat assembly on the vehicle floor and in which a foremost and rearmost (end) segment of the footrest are mutually adjustable to an inclined and / or upwardly projecting shelf to be able to form by means of at least one other, middle segment. The Adjustability of the foremost and rearmost segments relative to one another includes in this case that only one of the (end) segments is displaceable along the seat longitudinal axis, while the other (end) segment is fixed or only pivotally mounted, as is an adjustment of the two (end) segments. ) Segments towards each other along the seat longitudinal axis. In the proposed solution should be provided in particular that by shortening a distance between a foremost and rearmost (end) segment of the footrest along the seat longitudinal axis at least one middle segment - thus also several middle segments which are hinged together - an adjustment experienced with a directional component perpendicular to the longitudinal axis of the seat and thus a raised footrest can be provided with inclined and / or increased storage area.

In one embodiment, therefore, the footrest at least partially parallel to each other and mutually hinged (middle) segments, which provide by shortening a distance between a foremost and a rearmost segment and thus an adjustment of these segments to each other to a storage area for the feet of a seat occupant which is variable in their inclination and / height.

Basically, the at least one power-operated along the seat longitudinal axis drivable (drive / end) segment also, based on the at least one middle segment, front / foremost or rear / rearmost segment. For the transmission of an adjusting force to the driven by the drive mechanism (drive) segment can act on this segment while a force transmission means.

In one embodiment variant, the at least one (drive) segment which can be driven externally by means of the drive mechanism is displaceably guided in a guide of the seat assembly along the seat longitudinal axis. Accordingly, a pushing or pulling force can be applied to the driven segment to displace it along the guide. Thus, a distance between the driven segment and a rearmost or foremost segment of the footrest can be reduced and an erection of the at least one middle segment can be achieved, which then forms the inclined and / or elevated storage surface over this. Of course, a guide for a segment of the footrest does not necessarily have to be straightforward, but may also define a guideway having a single or multiple angled and / or curved course. Such an angled and / or curved course, for example, in the manner of a slotted guide lead to a lifting of at least one segment of the footrest when the respective segment is adjusted along this guide.

With the aid of the segments, in the at least one storage position of the footrest a curvature protruding from the starting position can be defined, on which the inclined and / or elevated storage surface is formed. An inclined and raised storage surface is thus formed, for example, on a side facing the vehicle seat of the curvature. Alternatively or additionally, over at least one middle segment, an increased (and not inclined) depositing surface can be formed on a plateau of the curvature. This includes in particular a variant in which a middle, erected segment is aligned substantially horizontally in the storage position. In the case of such a horizontally deployable middle segment, this can have in a development on a lateral edge an additional support rod for stabilizing the storage area defined hereby. The support rod is arranged and fastened in such a way that, in a storage position in which a set-up middle segment is oriented substantially horizontally, the support rod extends at right angles to the deposit surface defined herewith. The support rod can in this case be guided via a corresponding kinematics in a lateral guide, in particular in a guide on which at least one segment of the footrest is guided displaceably.

As already explained above, the footrest in one embodiment variant can also have at least four segments which are connected to one another in an articulated manner and can be displaced relative to one another. In particular, for the definition of an upwardly projecting curvature several articulated interconnected, middle segments can then be provided. By providing a plurality of hingedly interconnected middle segments, in particular the contour of the curvature can be set finer and more evenly than when, for example, in two segments that are always angled when setting up the footrest to each other and optionally oriented at an acute angle to each other when setting up the footrest ,

In particular, with regard to the adjusted contour of the raised footrest in a storage position and the exact specification of the seat user made available storage area with one or more middle segments can be provided in a variant that at least two segments of the footrest have mutually different dimensions. This includes in particular that, based on an extension along the seat longitudinal axis in the starting position of the footrest, at least a narrower segment and a wider segment are provided. With several strung narrower segments, which are hinged together, different contours can be set very flexibly. On the other hand, wider segments can have the advantage that a comparatively large area is already provided for this purpose, which supports a foot of the seat occupant. When using segments of different widths, advantages can be achieved with regard to both aspects. In a further development, for example, at least three segments are provided which have mutually different dimensions.

In one embodiment variant, at least two segments of the footrest are articulated to one another via two connecting elements, of which a first connecting element is assigned to one segment and a second connecting element to the other segment. The first and second connecting elements are in each case fixed to the respective associated segment and are connected to each other via a hinge connection which defines a hinge axis about which the two segments can be pivoted relative to each other.

In one embodiment, a joint axis of articulation, e.g. a hinge pin, provided on one of the connecting elements, which is displaceably guided on a long or slot hole of the other connecting element. Such a relative displacement of the two connecting elements is transverse to the hinge axis allows. This can be useful for a targeted lifting of the at least one middle segment of the footrest, in particular in the case of a slot or slot hole running inclined to a guide track for the drivable segment. By moving the hinge axis within the slot or slot hole, a force application point for an introduced into the footrest pressure force by means of displacement of the driven segment along the longitudinal axis of the seat can be changed at an adjacent connecting element, so over this one lever arm is defined to the adjacent To push connecting element (and thus the associated segment) in a further displacement of the driven segment upwards.

One of the first and second connecting elements used in a development, for example, for targeted lifting of the segments for taking a storage position by this connecting element during adjustment of the driven segment against a - in the installed state of the seat assembly - solid ground contact element moves, for. a pin-shaped contact element and / or a contact element with a ramp-shaped contour. In addition, an elastic displacement element can be provided on at least one of the connecting elements, which cooperates with adjustment of the segments of the footrest with a bottom-fixed contact element such that a displacement of a portion of the elastic displacement element takes place, which acts on another connecting element, and thereby a displacement of the other Connecting element (and thus the segment associated therewith) relative to the provided with the elastic displacement element connecting element causes. When adjusting the driven segment of the footrest here moves, for example, the elastic displacement element on the contact element, so that this elastically deformed and acts on the other connecting element, whereby the other connecting element is displaced under the action of the elastic displacement element relative to that connecting element, where the elastic displacement element is fixed. In one embodiment, the elastic displacement element comprises a leaf spring. Such a leaf spring is then fixed, for example, with one end to the one (first) connecting element and abuts with another, free and elastically displaceable end to the other connecting element.

In one embodiment, the drive mechanism includes at least one flexible power transmission means for transmitting an adjustment force to the at least one drivable segment. This flexible power transmission means may be, for example, a cable or Bowden cable.

In one possible development, the flexible force transmission means extends in the starting position of the footrest at least partially below the segments forming the planar support surface. For example, the power transmission means extends with at least a portion below and substantially parallel to the adjacent and mutually hinged middle segments when the footrest is in the home position.

In one embodiment, the flexible power transmission means is deflected on the one hand on a front relative to the seat longitudinal axis deflecting element, for example a deflecting piece or a rotatably mounted guide roller, and on the other hand on a relative to the seat longitudinal rear deflecting element. For example, it is comparatively easy to apply an adjustment force acting along the seat longitudinal axis to the driven (drive) segment for the adjustment of the footrest by means of the cable or Bowden cable.

In one embodiment, the drive mechanism comprises a movable rod, eg a rack or spindle, as a power transmission means. An associated with this rod, slidably held in a guide slider is then connected to a driven segment of the footrest.

A drive motor and in particular a drive shaft of a drive motor of the drive mechanism can also be positioned axially parallel to hinge axes of the hinged segments of the footrest. About the rotational movement of the drive and an associated lever then a segment of the footrest can be raised. The adjustment of a segment by an angle then leads, for example, to retighten further segments of the footrest.

The footrest can be adjusted, for example, in different storage positions in which the segments form a shelf, which is inclined relative to the shelf in the starting position by up to 45 °. In this context, for example, be provided that different storage positions of the footrest are adjustable, in which the respective storage surface for the feet of a seat occupant has an inclination in the range of 0 ° to 45 ° relative to the shelf in the starting position. The footrest can thus be set up via the segments hinged to one another such that a storage area facing the vehicle seat and defined by at least one (middle) segment can be tilted by up to 45 ° relative to the horizontal when the seat assembly is mounted in a vehicle as intended.

The seat assembly may further comprise an electronic control device or be coupled to such an electronic control device by means of the footrest is automatically adjustable in dependence on a voltage applied to the electronic control device manipulated variable in the at least one storage position. The voltage applied to the electronic control device manipulated variable may be indicative of a seating position of the vehicle seat, for example, and predetermine a (starting and / or filing) position of the footrest corresponding to the respective seating position.

In one embodiment, the adjustable footrest integrated at least one additional functionality, which is basically independent of the support of the feet of a seat occupant. For example, it may be provided that a display is provided on or in at least one segment of the footrest. By setting up the footrest, the display can then be moved into a viewing position for the seat user.

Alternatively or additionally, an additional seat opportunity can be provided by means of the footrest in one (of possibly several possible storage positions). The raised footrest can thus also be set up and provided to form a seat surface and / or a backrest for a person, for example as an additional seat option when the vehicle is stationary, in particular parked.

In one embodiment variant, the drive mechanism is coupled mechanically and / or electronically with an adjustment mechanism for seat longitudinal adjustment of the vehicle seat. Thus, for example, an actuation of the footrest via the incorporation of the adjusting mechanism for the seat-length adjustment. A drive of the adjusting mechanism for the seat longitudinal adjustment then serves as a drive for adjusting the footrest. A mechanical coupling between the adjustment mechanism for the seat-length adjustment and the drive mechanism of the footrest is, for example, via a connecting element, e.g. in the form of a locking pin, provided which engages in an adjustable rail of the adjusting mechanism.

As part of the proposed solution, a vehicle is provided with at least one seat group according to the invention. In such a vehicle, the footrest can then be integrated into a floor of the vehicle so that a part of the vehicle floor lying in front of the vehicle seat can tilt and / or increase in the at least one storage position.

In one embodiment, a loading space is made accessible via the footrest in the at least one storage position, which is covered in the starting position of the footrest. The footrest thus serves at least partially as a cover for a (for example, provided below the vehicle floor) loading space. In particular, in the case of a seat assembly with a vehicle seat for a rear row of seats of a motor vehicle, a part of a boot floor can also be formed in such a way over the footrest. If, for example, the footrest is set up, a loading space provided below the boot floor is accessible in order to be able to arrange objects therein.

The attached figures illustrate by way of example possible embodiments of the proposed solution.

1 shows a perspective view of a seat assembly SB with a vehicle seat S and one along a seat longitudinal axis L in front of the vehicle seat S arranged footrest A , which is integrated in a vehicle floor. The footrest A consists of several articulated, narrow and parallel oriented segments 10 . 11 and 12 , which - depending on the position of the footrest A - different shelves F . fa for supporting the feet of a seat occupant. The footrest A This can be done by adjusting the segments 10 . 11 and 12 in particular, different degrees of curvature around a side surface of a resulting curvature W a sloping and raised shelf fa train the vehicle seat S is facing.

For this purpose, for example, an end or drive segment 10 the footrest A in a guide along the seat's longitudinal axis L power-operated by means of a drive mechanism various. Such can be a distance of this end or drive segment 10 to one the other end of the footrest A along the seat's longitudinal axis L forming end segment 12 be shortened. As a result, learn the articulated and between these two end segments 10 and 12 lying (middle) segments 11 an adjusting force with a directional component along a spatial direction Z perpendicular to the seat's longitudinal axis L up. The displacement of the driven end or drive segment 10 along the seat's longitudinal axis L thus leads, for example, to (further) setting up the footrest A , In this way, the footrest integrated in the vehicle floor B can A on the one hand via the adjacent segments 10 . 11 and 12 in a starting position of the footrest A a flat and flat shelf F in front of the vehicle seat S form. On the other hand, by one-sided shifting of the segments 10 . 11 towards each other the footrest A be placed locally, so that a curvature W with a vehicle seat S facing, inclined and elevated shelf fa and one of the vehicle seat S remote (filing) surface Fb arises.

In the embodiment of the 2A and 2 B are opposite to in the 1 variant shown individual segments 10 . 11a to 11g and 12 the footrest A differently dimensioned and in particular different ready. This can change the position and degree of curvature W be specified in more detail. Furthermore, this also optionally easier to specify which segment or segments when setting up the footrest A the vehicle seat S facing shelf fa for the support of the feet of the seat occupant. For example, this is a middle segment 11b seen with a width greater by a multiple near a driven seat side oriented (end or drive) segment provided. This wider middle segment 11b is when straightening the footrest A the vehicle seat S facing and then forms almost completely intended for the support of the feet shelf fa out. On both sides adjacent to this segment lying segments 11a and 11c then in particular a uniform contour of the curved footrest A specified.

In the variant of 2A and 2 B is further to be mounted in a vehicle interior frame frame G provided on which the segments 10 . 11a to 11g and 12 are held. On guides 3.1 and 3.2 this frame G , for example in the form of guide rails, is on the one hand a (front) end segment 12 fixed and held pivotally. On the other hand, at the guides 3.1 and 3.2 that by means of a drive mechanism 2 power-driven drive segment 10 slidably guided, at the same time the other (rear) end segment of the footrest A forms. For example, in particular, the drive segment 10 via a laterally protruding bolt portion on the guides 3.1 and 3.2 kept displaceable. For the articulated connection of the individual segments 10 . 11a to 11g and 12 with each other and the leadership of the drive segment 10 on the frame G are present each other opposite strip-shaped connecting elements 13.1 and 13.2 intended.

About the drive mechanism 2 can the drive segment 10 along the guides 3.1 and 3.2 starting from the flat starting position of 2A towards the end segment 12 be moved to the footrest A set up. To lower the footrest A Furthermore, the distance between the drive segment 10 and the end segment 12 be reduced again. Part of the drive mechanism 2 is a power transmission means in the form of a cable or Bowden cable 4 , This rope or bowden cable 4 engages the drive segment 10 and stands with a drive motor M the drive mechanism 2 (see. 6B) , For example, an electric motor in operative connection to the drive segment 10 along the two possible adjustment directions along the seat longitudinal axis L to draw. This is the rope or Bowden cable 4 at a front and rear end of the rack frame G in each case via a deflecting element in the form of a rotatable deflection roller 5.1 or 5.2 diverted. In this case, a tilting of the drive segment 10 at an adjustment along the seat longitudinal axis L to avoid, are the pulleys 5.1 and 5.2 each centered so that the rope or Bowden cable 4 also approximately in the middle of the drive segment 10 can attack.

The rope or Bowden cable 4 runs at the in the 2A and 2 B illustrated embodiment below the segments 10 . 11a to 11g and 12 the footrest A , Likewise, the drive motor of the drive mechanism 2 below the segments 10 . 11a to 11g and 12 housed and optionally on the frame G be fixed. The drive mechanism 2 can build comparatively compact, as well as the integrable in the vehicle floor footrest A.

Like in the 2 B shown by dashed lines, can in the when setting up the footrest A the vehicle seat facing and the storage area fa forming segment 11 in a possible development also a display D be used. About this display D For example, vehicle information can be displayed and / or vehicle media can be controlled and / or displayed.

The installation and lowering of the footrest A can be automated depending on a seating position of the vehicle seat S by means of an electronic control device SE to be controlled. The electronic control device SE can, for example, a manipulated variable p received as an adjustment signal for a particular seating position of the vehicle seat S indicative and thus automatically raising or lowering the footrest A triggers.

Otherwise, as in the 2 B is shown as an example, on the established footrest A and the so along the seat longitudinal axis L shifted segments a cargo space R accessible in the starting position of the footrest A with the flat, flat shelf F covered and thus possibly closed. The cargo space R is thus in the starting position of the footrest A at least partially below the segments 10 . 11a to 11g and 12 and is only by putting up the footrest A made accessible. The cargo space R In this case, it may in particular be integrated at least partially in a rear-side cargo space of a motor vehicle or may be transferred thereto if the seat assembly SB is mounted as intended in a motor vehicle.

Notwithstanding the above explanations may of course also be provided that not the driven (end) segment 10 the vehicle seat side, rearmost segment of the footrest A forms, but along the seat longitudinal axis L fixed end segment 12 , Accordingly, then forms the other side of the vault W with the shelf Fb a way to support the feet of the seat occupant.

The 3 and 4 illustrate the connection of the individual segments 10 . 11a to 11g and 12 with each other based on the connection between (drive) segment 10 and the adjacent segment lying to it 11a as well as the following segment 11b , Each segment is two opposing fasteners 13.1 . 13.2 assigned, wherein in the 3 and 4 for distinctness a connecting element belonging to a segment 11a or 11b is assigned, with "13.1a" respectively "13.1b" is designated.

Each of the connecting elements 13.1 . 13.1a and 13.1b has a connecting body 130 with a segment recording 131 on. In this segment recording 131 in each case protrudes a lateral edge portion of the associated segment 10 . 11a or 11b and is incorporated herein in a form-fitting manner. Such is every connecting element 13.1 . 13.1a and 13.1b with the respective assigned segment 10 . 11a or 11b the footrest A fixed. During assembly, for example, the respective connecting element 13.1 . 13.1a and 13.1b to the assigned segment 10 . 11a or 11b attached or vice versa the respective segment 10 . 11a or 11b in the segment recording 131 of the respective connecting element 13.1 . 13.1a and 13.1b plugged.

At a front and rear end (relative to the seat longitudinal axis L ) has each connection segment 13.1 . 13.1a and 13.1b one connecting section each 132 . 133 or 134 on. Via interconnected connecting sections 134 . 132 or 133 . 132 two connecting elements 13.1b / 13.1a or 13.1a / 13.1 are the respective connecting elements 13.1b / 13.1a or 13.1a / 13.1 pivotable relative to each other and thus the segments fixed thereto 11b / 11a or 11a / 10 hinged together. For the definition of a physical pivot or joint axis, around the two fasteners 13.1b / 13.1a or 13.1a / 13.1 are pivotally relative to each other, in this case a (joint) pin or pin is provided. This pin or pin is in aligned through holes of two connecting portions 134 / 132 or 133 / 132 two adjacent fasteners 13.1b / 13.1a or 13.1a / 13.1 accommodates and thereby defines the physical joint axis for the two interconnected fasteners 13.1b / 13.1a and 13.1a / 13.1 , While present via a connecting section 132 two annular projections spaced apart from each other by a gap, each having a passage opening, are formed, for example, on an adjacent connecting element 13.1b a hollow cylindrical projection 134 provided, which can be inserted into the gap between the two annular projections. By inserting the bolt or pin is then an articulated connection in the manner of a hinge between the two connecting elements 13.1b and 13.1a produced.

At the the segment 11a associated connecting element 13.1a is a (rear) connection section 133 provided with a projection of a slot 1330 having. Also, this projection is in a gap between two annular projections of a connecting portion 132 another - here the drive segment 10 associated - connecting element 13.1 plugged in when the two segments 11a and 10 are mounted as intended. Unlike a hinge connection on a pair of connecting sections 134 and 132 is the bolt or pin that is the slot 1330 on the connecting element 13.1a matured, in this slot 1330 displaced. A joint axis defined by the bolt or pin for the two connecting elements 13.1a and 13.1 is thus on the connecting element 13.1a slidably guided.

Will now be the drive segment 10 in the direction of the (end) segment 12 the footrest A adjusted and thereby a compressive force on the connecting elements 13.1 . 13.1a and 13.1b for shifting the segments of the footrest A exerted, the joint axis of the two segments 13.1a and 13.1 inside the slot 1330 postponed. A force application point on the with the slot 1330 provided connecting element 13.1a exerted pressure force thus shifts, in such a way that on the newly occupied position a lever arm is defined to the with the slot 1330 provided connecting element 13.1a in a further displacement of the drive segment 10 to push up. In this way, it is possible to influence selectively which segment during an actuation of the footrest A (First) raised and pivoted relative to an adjacent segment.

Alternatively or additionally, a lifting of a segment 11b or 11a be controllable via at least one elastic displacement element. In the variant of 5 is such an elastic displacement element, for example in the form of a leaf spring 6 educated. An end 61 this leaf spring 6 is on the drive segment 10 , more precisely to its connecting element 13.1 , fixed. The other end 62 the leaf spring 6 is relative to the fixed end 61 elastically displaceable and lies on an underside of the footrest A the connecting element 13.1b of the segment 11b across from. Between the two ends 61 and 62 the leaf spring 6 forms the leaf spring 6 furthermore a convex curvature 60 out. About the vault 60 thus stands a portion of the leaf spring 6 down before.

On the frame G , present at the guide 3.1 of the frame G , Now is also a contact element in the form of a contact pin 130 intended. The contact pin 30 lies relative to the starting position of the footrest A in the area of the segment 11a that leads to the drive segment 10 is adjacent. By providing the contact pin 30 on the frame G is the contact pin 30 in the installed state of the seat assembly SB ground firmly.

Will the drive segment 10 along the seat's longitudinal axis L towards the (end) segment 12 the opposite end of the footrest A shifted to, the leaf spring is running 6 with its convex curvature 60 on the contact pin 30 on and is pressed over this elastic up. This affects the free end 62 the leaf spring 6 on the connecting element 13.1b of the segment 11b and pushes this relative to the drive segment 10 up. About the convex curvature 60 the leaf spring 6 Thus, a control contour is given to at an adjustment of the drive segment 10 a targeted lifting of a specific segment 11b to control.

In particular, via a lifting mechanism with contact pin 30 and leaf spring 6 and / or with longitudinally displaceable in a slot 1330 mounted joint axes of two fasteners 13.1a and 13.1 can be the contour of the footrest A influence specifically, so that different storage positions can be realized on this. Three possible storage positions are based on the 6A . 6B and 6C illustrated.

In the variant of 6A For example, the curvature, the two on the one hand the vehicle seat S facing and on the other hand of the vehicle seat S facing away from storage areas fa and Fb divided, in the area of the narrow segment 11b intended. This is the vehicle seat S facing, inclined storage surface fa larger than that of the vehicle seat S opposite, also inclined storage surface Fb , In addition, the inclination of the vehicle seat S facing storage area fa less and therefore less steep.

In the variant of 6B takes the footrest A the contour of an inverted "U" on, so on top through the segment 11d a flat, large storage area fc is formed, which extends horizontally. The side surfaces of the inverted U-shape are each characterized by a wider segment 11b or 11f Are defined.

In the storage position of 6C , which is essentially the filing position of the 2 B corresponds, is then in contrast to the storage position of the 6A turn the vehicle seat S facing shelf fa steeper and smaller than that of the vehicle seat S remote storage area Fb Here, the curvature in the area of the vehicle seat S closer narrow segments 11c is defined.
