Description

Prior ArtSeat frames for vehicle seats are generally known.Known vehicle seats comprise a seat frame on which a seat surface and a backrest of the vehicle seat are arranged. In this case, the legal safety regulations determine that a seat direction of a vehicle seat must be present during travel in the direction of travel.In known camping vehicles, in which the vehicle seats can be installed, there is mostly lack of space. The weight of the elements installed in the vehicle also plays an essential role for the total weight of the vehicle.It is known that vehicle seats are installed in such vehicles as a third seat behind the driver and passenger seats in the direction of travel in order to realize a seat during travel for a further person which corresponds to the safety guidelines.However, there is often a need for a seat for a further, fourth or fifth person to drive. This requirement is in turn opposed to the lack of space mentioned and thus the lack of installation possibility of a further vehicle seat.Object and Advantages of the InventionThe object of the invention is to provide an improved device for realizing an additional vehicle seat. In particular, an improved or alternative device, e.g. with a seat frame, can be provided which meets legal safety standards.The object is achieved by the features of claim 1.In the dependent claims advantageous and convenient embodiments of the invention are given.A device for a seat frame is proposed, wherein the device has a cross bar and a joint unit, wherein the cross bar can be arranged on a seat frame and / or on a vehicle floor of a vehicle by means of the joint unit, wherein the joint unit has an axis of rotation, wherein the cross bar is rotatably mounted about the axis of rotation of the joint unit, such that the cross bar can be released, wherein in the released state of the cross bar a seat element and / or a backrest element can be arranged on the cross bar, such that an additional seat can be realized. This makes it possible to realize an additional seat in a comparatively simple and cost-effective manner.For example, the seat frame is designed as a seat frame for a vehicle seat and / or a vehicle seat bench. It is conceivable that the seat frame has a vertical support and a cross strut, wherein the vertical support is configured such that it can be connected to the vehicle in an upright manner in the region of a vehicle floor of a vehicle. It is conceivable that the device is arranged on the seat frame in particular by means of the joint unit. For example, the cross bar is rotatably mounted about the axis of rotation of the joint unit relative to the seat frame.For example, the vehicle seat or the vehicle seat bank is designed as a recreational vehicle seat, a recreational vehicle seat, a recreational vehicle seat and / or a caravan vehicle seat.For example, the joint unit is connected to the vertical support and / or to the cross strut. It is conceivable that the joint unit is directly connected to the vertical support and / or to the cross strut. It is conceivable that the cross beam is rotatably provided about the axis of rotation relative to the vertical support and / or relative to the cross beam.It is conceivable that the cross beam is present as an elongate strut. It is conceivable that the cross bar is designed as an elongated profile, e.g. as a hollow or solid material profile. For example, the profile is designed as a square tube.For example, the cross bar is connected with a first end to the joint unit. It is conceivable that the cross bar is connected to the seat frame solely with the first end of the cross bar or exclusively with the first end of the cross bar. For example, the cross bar is connected to the seat frame exclusively by means of the joint unit.It is conceivable that the cross bar is present such that it can be moved from a stowage position into a functional position and back. For example, the cross bar can be moved about the axis of rotation from the stowage position into the functional position and back. For example, the cross bar is provided in the functional position in a freely exposed manner. For example, the cross bar is movable from the stowage position into the functional position and back along a vertically oriented movement plane. It is also proposed that the cross bar be movable from the stowage position into the functional position and back along a horizontally oriented movement plane. The planes of movement can be seen in relation to the installed state in the vehicle. For example, in the installed state of the device in the vehicle, the horizontally oriented movement plane is thus oriented parallel to a vehicle floor or parallel to a direction of travel of the vehicle, while the vertically oriented movement plane is oriented transversely or perpendicularly to the extent of the vehicle floor or transversely or perpendicularly to the direction of travel of the vehicle.For example, the seat frame has a vertical support and a transverse strut oriented transversely with respect to the vertical support. It is conceivable that in the mounted state of the seat frame in the vehicle, the vertical support is vertically oriented in the longitudinal direction of the vertical support. It is also conceivable that at a lower end section of the vertical support, the vertical support can be connected to the vehicle in the region of a vehicle floor of the vehicle. For example, the seat frame has exactly one vertical support. It is conceivable that the seat frame has two or more vertical supports. It is also conceivable for the seat frame to have exactly two, exactly three or exactly four vertical supports. If the seat frame has two or more vertical supports, the vertical supports are present spaced apart from one another, for example. For example, the vertical supports are provided at a distance from one another transversely to a seat direction of the vehicle seat or vehicle seat bench that can be realized with the seat frame.The cross strut is preferably oriented horizontally with respect to the usable or installed state in the vehicle. A height of the seat frame, e.g. corresponding to the height of the vertical support, can be seen perpendicularly with respect to the installation state of the seat frame. The vertical extension coincides, for example, with the longitudinal axis of the vertical support or of the plurality of vertical supports. This means that when the seat frame is installed on the horizontally oriented vehicle floor, the vertical support is e.g. perpendicular. However, it is also conceivable for the vertical support to be present tilted about the vertical, for example in a direction transverse to the seat direction. The cross strut is oriented horizontally, for example, with its longitudinal axis. The seat direction is present, for example, aligned perpendicular to the vertical support or perpendicular to the longitudinal axis of the vertical support and perpendicular to the transverse strut or perpendicular to the longitudinal axis of the transverse strut. For example, the longitudinal axis of the transverse strut is oriented transversely, e.g. perpendicularly, to the longitudinal axis of the vertical support.For example, in order to support the seat frame on the vehicle floor, the seat frame has a support section in order to support the seat frame on the vehicle in the arranged state of the seat frame in the vehicle. For example, the support section protrudes in the seating direction beyond a plane which is determined by a front side of the vertical support which is situated at the front in the seating direction. It is also conceivable for the support section to be fastenable to the vehicle floor via a lower support section end, wherein the lower support section end is spaced apart from the lower end of the vertical support in the seat direction. The support section is, for example, an elongated rigid profile directed forwards downwards, e.g. obliquely in the seat direction or forwards, e.g. in the form of a support foot. For example, the support section extends in a space below a seat height or seat surface height of the seat or its seat padding that can be formed with the frame.For example, the seat frame has a support section in the form of a support foot, wherein the support foot is connected to the vertical support by a first end and is configured such that it can be connected to the vehicle by a second end, e.g. the lower support section end, in the region of the vehicle floor of the vehicle, wherein the support foot, in the arranged state on the vehicle, is arranged so as to project obliquely downward in the direction of travel with the first end on the vertical support. It is conceivable that the joint unit is arranged on the support foot.The device is designed, for example, as a structural unit which can be installed in an interior of the vehicle. For example, the device can be fastened, for example screwed, to a vehicle floor. It is also conceivable for the device to be fixable, for example additionally, to a vehicle pillar, a wall structure or ceiling structure of the vehicle. It is conceivable that the seat frame can be fastened to a vehicle floor. It is also conceivable that the cross bar can be fastened to a wall or a wall structure of the vehicle. For example, the cross bar is configured to be connected to the wall or the wall structure of the vehicle in the released state. This can improve stability of the device in the released functional state.It is also proposed that a safety element of the device or a safety element of the vehicle seat of the device is arranged on the wall or the wall structure. For example, the safety element is designed as a belt buckle, a belt deflector, a belt fastening and / or a belt retractor. As a result, the safety requirements can be met comparatively easily.For example, the vertical support and / or the cross strut is designed as an elongate profile. For example, the vertical support and / or the cross strut is designed as a hollow or solid material profile, for example as a square tube. It is also conceivable that a vertical support is formed from two or more profiles. For example, the two or more profiles of the vertical support are connected to one another along the longitudinal axis of the vertical support. For example, the vertical support has sections vertically above the cross strut, e.g. horizontally slotted sections. This allows a desired plastic deformation of the vertical support to be predefined, which in the case of loading takes place when a limit tensile load in the seat direction is exceeded.The term "seat direction" is to be understood to refer to a person sitting in the vehicle seat formed with the device.For example, the cross bar has a longitudinal axis. For example, the longitudinal axis of the cross bar is parallel to the longitudinal axis of the vertical support in the storage state. It is also conceivable for the longitudinal axis of the cross bar to extend in the seat direction in the stowed state. For example, in the stowed state, the cross member is present aligned transversely to the longitudinal axis of the cross member and transversely to the longitudinal axis of the vertical support. This realizes a comparatively compact, space-saving construction in the storage state.For example, the cross bar is moved from the stowage state into the functional state about the axis of rotation at an angle of less than 185°, in particular at an angle of less than 180°. It is conceivable that an angle of the rotation range of the cross bar about the rotation axis is less than 100° or less than 95°. For example, the cross bar is rotated from the stowage state into the functional state and vice versa by exactly the angle 90° about the axis of rotation D. The angle is formed by the longitudinal axis of the cross bar in the stowed state to the longitudinal axis of the cross bar in the functional state. For example, the cross bar is rotated about the axis of rotation from the stowed state into the functional state by an angle range between 80° and 100°, for example between 85° and 100° or between 85° and 95°.For example, the cross bar can be moved with the longitudinal axis of the cross bar along the movement plane of the cross bar from the stowed state into the functional state and back.For example, the longitudinal axis of the cross member is oriented parallel to the longitudinal axis of the cross member in the functional state. For example, the longitudinal axis of the cross bar is present in the functional state transversely to the longitudinal axis of the vertical support. It is conceivable that the longitudinal axis of the cross bar extends transversely to the seat direction in the functional state. For example, the longitudinal axis of the cross bar in the functional state together with the seat direction clamps a surface which is oriented parallel or approximately parallel to a seat surface of the vehicle seat formed with the seat frame.It is also proposed that the axis of rotation of the joint unit is present aligned horizontally or vertically. For example, the axis of rotation extends in the horizontal or in the vertical.For example, the axis of rotation of the joint unit is provided aligned parallel to the longitudinal axis of the vertical support. It is also conceivable for the axis of rotation of the joint unit to be present parallel to the longitudinal axis of the transverse strut. For example, the axis of rotation extends in the seat direction or is present transversely to the seat direction. For example, the joint axis of the rotary unit is oriented transversely to the longitudinal axis of the cross beam.It is also proposed that the joint unit has a holding mechanism in order to fix the cross bar relative to the seat frame in a pivoted-in state on the seat frame and / or in a released state on the seat frame. This prevents unintentional movement of the cross bar from the stowed state into the functional state or vice versa.For example, the holding mechanism has a latching mechanism. For example, the latching mechanism is present in such a way that the cross bar latches automatically in the functional position and / or in the stowage position. For example, a locking of the holding mechanism is releasable, e.g. manually by a user. It is conceivable for the holding mechanism to have a securing bolt which fixes the cross bar in the functional position and / or in the stowage position. It is conceivable that the holding mechanism is designed as a one-hand locking.It is likewise proposed that the device has the seat element for the additional seat, wherein the cross bar has mounting elements for arranging the seat element, wherein the seat element can be detachably connected to the cross bar by means of the mounting elements, such that the additional seat can be realized. This makes it comparatively simple to implement an additional seat.For example, the seat element has latching hooks which engage in latching eyes, so that the seat element can be suspended or suspended from the cross bar. It is also conceivable for the vehicle seat to have the seat element. For example, the seat element has a support surface which, in the arranged state, engages on an underside of the cross bar, so that the seat element is supported on the cross bar.It is also proposed that the device has the backrest element for the additional seat, wherein the cross bar has mounting elements for arranging the backrest element, wherein the backrest element can be detachably connected to the cross bar by means of the mounting elements, such that the additional seat can be realized. As a result, the backrest element can be comparatively easily stowed in the unused state. For example, the device comprises the backrest element and / or the seat element.In a proposed variant, the seat element and the backrest element are connected to one another in an articulated manner as a unit, such that a seat surface of the seat element is present in a pivotable or rotatable manner in the direction of a bearing surface of the backrest element and vice versa. It is conceivable that this unit can be arranged on the cross beam. For example, the cross bar has attachment openings into which mounting bolts of the unit can be arranged in an engaging manner, e.g. inserted.For example, the device is designed such that the cross bar can be moved from the functional state into the stowage state exclusively in the disassembled state of the seat element and of the backrest element from the cross bar. It is conceivable that the seat element or the backrest element, in the arranged state on the cross bar, block a movement of the cross bar from the functional state into the stowage state.For example, the seat frame is designed for the arrangement of a seat cushion and a person restraint system. As a result, a vehicle seat with the seat frame can be realized. For example, the seat frame has the seat element and / or the backrest element. It is conceivable that a seat cushion can be arranged on the seat element and / or on the backrest element. For example, a person sitting in the seat direction can be secured in a vehicle with the person restraint system in the mounted state of the seat frame.It is further proposed that the seat frame has a seat surface element, wherein the joint unit can be arranged on the seat frame below the seat surface element. As a result, the device is of comparatively space-saving design.For example, the joint unit is present in the region of the seat surface element. It is conceivable that the joint unit is present below a seat surface of the seat surface element. As a result, the joint unit is arranged on the seat frame in a manner hidden from view for a viewer.It is also proposed that the cross bar is positioned below the seat surface element in the pivoted-in state on the seat frame. As a result, the cross bar can be comparatively easily stowed.For example, the cross bar is present at the level of the cross bar. However, it is also conceivable for the cross beam to be present below the cross beam. For example, the longitudinal axis of the cross member is oriented parallel to and spaced apart from a movement plane of the cross member from the stowed state into the functional state.It is likewise proposed that the cross bar extends along a longitudinal axis into a longitudinal extent, wherein the cross bar extends along a longitudinal axis of the vertical support with the longitudinal axis of the cross bar in the pivoted-in state on the seat frame. This realizes a further variant of a comparatively simple stowage of the cross bar in the stowage state.For example, the vertical support extends from the connection in the floor area on the vehicle along the longitudinal axis of the vertical support as far as an opposite end of the vertical support. For example, in the pivoted-in state on the seat frame, the cross bar extends with the longitudinal axis of the cross bar parallel to the longitudinal axis of the vertical support.It is also proposed that the device has a vertical strut, wherein the vertical strut can be arranged on the seat frame and / or on the vehicle floor. It is further conceivable that a retaining element for a seat belt arrangement of the additional seat is provided on the vertical strut. For example, the vertical strut has a fastening element in order to fasten the vertical strut in the region of the vehicle floor, e.g. on the vehicle frame of the vehicle. It is also conceivable for the vertical strut to have a fastening element in order to fasten the vertical strut to the seat frame, for example to the vertical support.For example, the joint unit has a holding mechanism and the holding mechanism of the joint unit is designed to fix the cross bar relative to the vertical bar in a pivoted-in state on the vertical bar and / or in a released state on the vertical bar.It is also conceivable that the seat frame has the vertical strut, wherein the vertical strut has a longitudinal axis and the vertical strut is present with the longitudinal axis parallel to and spaced apart from the vertical strut. It is conceivable for the vertical strut to be directly connected to the transverse strut.In one possible embodiment of the device, the device has the cross bar, the joint unit and the vertical strut, wherein the cross bar is arranged on the vertical strut by means of the joint unit, wherein the device can be arranged on a vehicle frame of a vehicle by means of the vertical strut, such that an additional seat can be realized in a vehicle.It is also conceivable for elements of a belt system, for example a retaining element, to be arranged on the vertical strut. For example, a belt deflector of the belt system is arranged on the vertical strut. It is conceivable that the cross bar in the storage state is oriented with the longitudinal axis parallel to the longitudinal axis of the vertical strut. It is conceivable that the cross bar in the storage state abuts or abuts the vertical strut along the longitudinal axis.It is also proposed that the device has a connecting element which is designed such that it can be connected to the vehicle or the vehicle frame, wherein a safety element, for example a belt buckle of the belt system, can be arranged on the connecting element, wherein the connecting element is present in the arranged state of the device in the vehicle at a distance from the seat frame or from the vertical strut in a direction transverse to the direction of travel. For example, the belt buckle is connected to the connecting element via a belt whip. This realizes an arrangement of the safety element, e.g. of the belt buckle, in the region of or at the height of the seat element. It is also conceivable for the connecting element to be connected to the vertical strut by means of a connecting strut.For example, the vertical strut extends along the longitudinal axis of the vertical strut up to the level of the seat element. It is also conceivable for the vertical strut to extend as far as an upper end of the backrest element arranged on the cross member. It is conceivable for the vertical strut to have a length along the longitudinal axis of between 250 mm and 1200 mm. For example, the length of the vertical strut is between 250 mm and 1000 mm. It is also conceivable for the length of the vertical strut to be between 350 mm and 800 mm or between 350 mm and 650 mm. For example, the length of the vertical strut is at least 250 mm, 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, 550 mm, 600 mm, 650 mm, 700 mm, 750 mm, 800 mm, 850 mm, 900 mm, 950 mm, 1000 mm, 1050 mm, 1100 mm or 1150 mm. It is also conceivable for the vertical strut to extend at most over a length of 300 mm, 350 mm, 400 mm, 450 mm, 500 mm, 550 mm, 600 mm, 650 mm, 700 mm, 750 mm, 800 mm, 850 mm, 900 mm, 950 mm, 1000 mm, 1050 mm, 1100 mm, 1150 mm, 1200 mm or 250 mm.It is likewise proposed that attachment elements for attaching an isofix retaining branch of an isofix child seat are present on the cross member. This allows an isofix child seat to be attached to the device adjacent to the vehicle seat according to safety standards. For example, the connecting element is present as a bore. An isofix holder branch is fastened to the cross beam, for example, in the form of a U-shaped bow. It is also conceivable that isofix holder legs are present on the unit formed by the backrest element and the seat element.For example, the cross bar has isofix holder legs. It is conceivable that two isofix holder legs are provided spaced apart from one another on the cross beam. It is also conceivable that a holding element for a top tether of the child seat is provided on the backrest element, so that the top tether can be fastened to the holding element. For example, the holding element is designed as an opening or as an eyelet, into which a hook of the top tether can be hooked.It is also proposed that the device has a horizontal strut which is fastened at one end to the vertical strut, wherein the horizontal strut is present so as to project from the vertical strut in the seat direction, wherein a support for the horizontal strut is present at a second end of the horizontal strut for support and / or for fastening to the vehicle floor, wherein a seat support is present movably on the horizontal strut.It is conceivable that the seat support is designed as a strut on which the seat element rests in the arranged state. For example, the seat support is pivotable from a functional state to a stowage state and back. For example, the seat support forms a support for the seat element in the functional state. For example, the seat support is rotatably mounted on the horizontal strut by means of a pivot joint. For example, the support of the horizontal strut has mounting means for connecting the support to the vehicle, e.g. the vehicle frame, in the arranged state on the vehicle. For example, the axis of rotation of the pivot joint of the seat support is present in a vertically oriented manner. For example, the seat support is movable in a horizontally oriented movement plane from the functional state into the stowage state and back. For example, the horizontally oriented movement plane of the seat support is present offset in the vertical direction with respect to the horizontally oriented movement plane of the cross member. This prevents a collision during a movement of the cross member and the seat support from the functional state into the stowage state or vice versa. It is conceivable that the movement plane of the seat support is formed below the movement plane of the cross beam. For example, the movement plane of the seat support is present in the arranged state between a plane of the vehicle floor and the movement plane of the cross beam.As a possible embodiment, a seat frame with a device according to a variant as set forth above is proposed.As an exemplary variant embodiment, a vehicle seat bench or a vehicle seat with a device according to one of the aforementioned embodiments is proposed. For example, the vehicle seat has the device with the seat frame. It is conceivable that the seat frame is present as a seat frame of the vehicle seat.As a further conceivable variant embodiment, a vehicle, in particular a motorhome, is proposed with a device according to one of the aforementioned embodiments or with a vehicle seat bank according to the aforementioned variant embodiment.DESCRIPTION OF THE FIGURESFurther features and advantages of the invention are explained in more detail on the basis of an exemplary embodiment shown schematically.In detail, the following shows: FIG. 1 is a perspective view from obliquely laterally front above of a device which is provided arranged on a seat frame, FIG. 2 shows a perspective illustration of the device according to FIG. 1 with a unit comprising a backrest element and a seat element in a first mounting position, FIG. 3 shows a perspective illustration of the device according to FIG. 1 with the unit in a second mounting position, FIG. 4 shows a perspective illustration of the device according to FIG. 1 with the unit in the arranged state on the device.In FIG. 1, a device 1 and a seat frame 2 are shown.For example, the seat frame 2 has a first vertical support 3 and a second vertical support 4, which are connected to one another by means of a first cross strut 5. The first and the second vertical supports 3, 4 are connectable at a lower end 6, 7 to a vehicle floor 8 of a vehicle. The first and the second vertical supports 3, 4 each extend along a longitudinal axis L 1, L 2 from the lower end 6, 7 to an upper end 9, 10. The first cross strut 5 extends along a longitudinal axis LQ transversely to the first and the second vertical supports 3, 4. It is conceivable for the second cross strut 11 to have mounting means in order to arrange or fasten a seat belt arrangement and / or in order to arrange or fasten headrests to the second cross strut 11.The device 1 has a cross beam 12 and a joint unit 13. In the embodiment shown in FIG. 1, the cross bar 12 is movable from a storage state 14 (shown in dashed lines) into a functional state 15 and back. In the functional state 15, the cross bar 12 is in the released state. In this case, the cross bar 12 can be moved in a horizontal movement plane. For this purpose, an axis of rotation D of the joint unit 13 is present in a vertically oriented manner.Mounting elements or mounting elements in the form of bores 16 and a thread 17 are formed, for example, on the cross bar 12 in order to fasten a backrest element 18 and / or a seat element 19. In the present exemplary embodiment, the backrest element 18 and the seat element 19 are formed as a unit 20, wherein the seat element 19 is rotatably connected to the backrest element 18. In this exemplary embodiment, the mounting elements and the mounting elements of the device 1 are correspondingly identical, since the mounting element or the mounting elements are provided for connecting the unit 20, with the result that the backrest element 18 and the seat element 19 can be mounted at the same time.For example, the hinge unit 13 includes a holding mechanism 21. The holding mechanism 21 is designed, for example, as a locking lever with a locking function. By means of the holding mechanism 21, the cross beam 12 can be fixed in a positionally fixed manner, for example, in the functional state 15 and / or in the stowage state 14.For example, the device 1 has a vertical strut 22. However, it is also conceivable for the vertical strut 22 to be part of the seat frame 2.The vertical strut 22 extends along a longitudinal axis LV in the vertical direction. It is conceivable that the vertical strut 22 can be connected to the vehicle at a first end 23 in the region of the vehicle floor 8. It is also conceivable that the vertical strut 22 is connected to the seat frame 2. It is conceivable that the vertical strut 22 can be connected to the vehicle and to the seat frame 2 or that the vertical strut 22 is connected exclusively to the vehicle or exclusively to the seat frame 2. For example, the vertical strut 22 is directly connected to the seat frame 2. For example, the vertical strut 22 is connected to the transverse strut 5. It is conceivable for the vertical strut 22 to be present screwed or welded to the transverse strut 5.It is furthermore conceivable for the vertical strut 22 to extend along the longitudinal axis LV from a lower end 23 to an upper end 24. It is conceivable, but not shown, that the vertical strut 22 extends with the upper end 24 up to approximately the height of the first transverse strut 5. For example, the vertical strut 22 extends with the upper end as far as the second transverse strut 11.For example, an element of a seat belt arrangement can be attached to the vertical strut 22. For example, a belt deflector 25 is fastened to the vertical strut 22 in the region of the upper end. It is conceivable that a belt retractor 26 is fastened in a lower region of the vertical strut 22. As a result, a strap 27 can be arranged on the vertical strut 22. As a result, the device 1 is designed as a device which is independent of further elements of a seat frame or of the vehicle and, by virtue of the design with vertical strut 22, provides a belt frame for a vehicle seat which meets the required safety standards.The joint unit 13 of the device 1 is connected, for example, directly to the vertical strut 22. It is conceivable for the belt retractor 26 to be arranged on the vertical strut 22 below the joint unit 13.In an embodiment which is illustrated in FIGS. 1 to 4, the device 1 additionally has a horizontal strut 28. For example, the horizontal strut 28 ideally has a purely comfort function and is not relevant for satisfying the safety standards of the vehicle seat. The horizontal strut 28 can be connected in a positionally fixed manner to the vertical strut 22, for example screwed or welded. It is furthermore conceivable that the horizontal strut 28 is supported on the vehicle by means of a support 29 in the region of the vehicle floor.For example, a seat support 30 is mounted on the horizontal strut 28 in a movable, in particular pivotable or rotatable manner.To produce an additional seat 31, the unit 20 comprising the backrest element 18 and the seat element 19 can now be arranged on the device 1. For this purpose, the unit 20 can have bolts 32 in order to plug the unit 20 onto the cross beam 12. The assembly sequence is represented here by the series of figures 2 to 4. In addition, the unit 20 can be detachably screwed to the cross beam 12 by means of a screw connection 33.In the assembled state of the unit 20, the seat element 19 is present resting on a bearing surface 34 of the seat support 30. It is also conceivable that the seat element 19 can be screwed to the seat support 30 by means of a further screw connection 35.It is also conceivable for isofix holder legs 36 to be formed on the unit 20.For example, the device 1 has a connecting element 37, which is designed to be connectable to the vehicle, e.g. in the region of the vehicle floor 8.
