Description

[0001] The invention relates to a seating device for a motor vehicle and to a motor vehicle with such a seating device.

[0002] Seating devices for motor vehicles are known in various designs from the prior art. These are designed in particular as vehicle seats in which a backrest and a seat are arranged to each other in such a way that a user of the seating device can always be easily seated on it.

[0003] Furthermore, seating devices are known in which the seat can be pivoted relative to the backrest, in particular from a seated position in which a user can be positioned sitting on the seat, to a storage position in which the seat is folded upwards and runs essentially parallel to the backrest. In the storage position, this provides space to arrange objects even in the area occupied by the seat in the seated position.

[0004] With known seating devices, it has proven disadvantageous that those where the seat is pivotable relative to the backrest are not, or at least not readily, approved for use while the vehicle is in motion. These often fail to meet the requirements in the event of a collision with the vehicle.

[0005] One object of an embodiment of the invention is to propose a seating device for a motor vehicle and a motor vehicle with such a seating device, in which, when not in use, the usable vehicle interior can be expanded and which simultaneously meets the legal impact requirements when in use.

[0006] This problem is solved by a seating device for a motor vehicle, which has a vehicle floor and a load-bearing vehicle wall, with at least one backrest which can be fixed or fixed to the vehicle wall and against which a user can be arranged with their back against it, with at least one load-bearing element which can be fixed or fixed to the vehicle floor and / or the vehicle wall, with at least one seat element which is rotatably or pivotably fixed to the load-bearing element about a rotational or pivoting axis and which can be converted from a sitting position in which a seat surface of the seat element is arranged parallel or obliquely to the vehicle floor and a user can be arranged with their buttocks on it, to a stowed position in which the seat surface of the seat element is arranged parallel or obliquely to the backrest, with at least one receptacle fixed in or on the vehicle floor or on the load-bearing element.and with at least one load-bearing support unit which is rotatably fixed to the seat part on the side facing away from the seat surface and which, in the seated position, can be fixed with a free end in or on the receptacle and which, in the arrangement fixed in or on the receptacle, supports the seat part against the vehicle floor and secures it against being moved into the stowed position.

[0007] Because the seat cushion can be moved from the seated position to the stowed position and back, the available space in the vehicle interior can be expanded when the seat is not in use. Since the seat includes a load-bearing support unit that braces the seat cushion against the vehicle floor in the seated position and prevents it from being moved into the stowed position, the seat meets the legal impact requirements.

[0008] It proves advantageous if the seat surface of the seat part is spaced away from the back part without contact in the storage position, or if it is in contact with the back part, in particular lying flat against it.

[0009] In principle, it is conceivable that the seat section can be manually moved from the sitting position to the storage position and back again with respect to the back section.

[0010] It is advantageous if the seating device includes at least one clamping means arranged between the seat part and the support means, which pre-tensions the seat part into the storage position and / or at least one locking means arranged on the seat part, by which the seat part can be releasably fixed in the storage position against being moved into the seating position.

[0011] If a clamping device is arranged between the seat and the support structure, which pre-tensions the seat into the stowed position, the seat is automatically moved into this position whenever the support unit is released from its mount. Furthermore, the clamping device ensures that the seat cannot move unintentionally in the stowed position.

[0012] Because the seat device includes a locking means arranged on the seat part, the seat part can be detachably fixed in the stowed position. This proves particularly advantageous in embodiments of the seat device where, for example, no clamping means is provided, whereby, after manual transfer from the seated position to the stowed position, the seat part is fixed in the stowed position against automatic movement by the locking means.

[0013] Furthermore, embodiments are conceivable in which both a clamping device and a locking device are provided.

[0014] The support unit can, in principle, be designed in any way, provided it fulfills the technical function of fixing the seat part in the seated position relative to the vehicle floor or to the load-bearing element.

[0015] The support unit can be implemented simply and cost-effectively if the support unit comprises at least one rod-shaped support element that is rotatably arranged on the seat part at one end away from the axis of rotation or pivoting and that can be arranged and fixed with a locking section in the at least one receptacle, in particular if the support unit comprises at least two support elements running parallel to each other, which are arranged on opposite sides at the end away from the support means and / or if the support unit comprises at least one planar, plate-shaped support means that is fixed to the at least one support element.

[0016] The seat section can be easily supported against the vehicle floor or the load-bearing element in the seated position by means of at least one rod-shaped support element. The support element is rotatably fixed to the seat section, so that in the seated position it is essentially vertical, in particular inclined or parallel to the vertical axis of the vehicle, and is rotated relative to the seat section when moving the seat section from the seated position to the storage position, and is arranged parallel to the seat surface of the seat section in the storage position. The at least one rotatably fixed support element can be rotatable about a pivot axis that runs parallel or transversely to the rotation or pivot axis of the seat section.

[0017] If the support unit comprises at least two support elements, these can be arranged at the outer ends of the seat part.

[0018] The planar, plate-shaped support element can be arranged on only one support element or, if at least two support elements are provided, it can be fixed to both support elements.

[0019] In order to ensure that the at least one support element runs essentially vertically in the seated position and rests against the seat part when being moved into the storage position, it proves advantageous in a further development of the latter embodiment if the support unit comprises at least one steering element which is rotatably fixed at one end to a support element, in particular adjacent to the locking section, and which is rotatably fixed at one end opposite the support element to at least one of the at least one support means about a steering axis.

[0020] The support element and steering element can be arranged automatically in a technically efficient and compact manner if, in the seated position, the support element is essentially parallel or oblique to the vertical axis of the motor vehicle and the steering element is essentially parallel or oblique to the vehicle floor, and / or if, in the stowed position, the support element and the steering element are essentially parallel or oblique to the vertical axis of the motor vehicle.

[0021] Because the support element is rotatably arranged on the seat part and rotatably connected to the steering element on the side facing away from the seat part, and because the steering element is rotatably arranged on the support means, the support element, steering element, support means and seat part form a quadrangular system.

[0022] When moving the seat from the seated position to the stowed position, the angle between the support element and the steering element is increased until the stowed position is reached, in which the support element and steering element are essentially parallel to each other and continue their paths. This ensures a flat and compact arrangement of the support element and steering element in the stowed position and a stable, supported arrangement of the support element by the steering element in the seated position.

[0023] The receptacle can be of any design, provided it serves the function of allowing the support unit, in particular the at least one rod-shaped support element with its locking section, to be fixed in or on the receptacle. The receptacle can, for example, include a recess or the like.

[0024] In one embodiment of the seating device, it proves advantageous if the receptacle includes a locking mechanism in which the support element with its locking section can be detachably fixed and / or if the locking means detachably fixes the seat part in the storage position relative to the support element in a fixed position, in particular rotationally fixed.

[0025] The support element can be secured in the locking mechanism by force-fit and / or form-fit releasable locking. The locking mechanism can, for example, be manually operated to remove the support element and its locking section from the receptacle.

[0026] The locking device can, for example, block the seat part from twisting relative to the support element when the seat part is in the stowed position.

[0027] In one embodiment of the seating device, it proves advantageous if the seat part comprises a frame and a seat cushion fixed to the frame, wherein the seat part is rotatably fixed to the support element with the frame, and wherein the at least one support element is fixed to the frame.

[0028] The inclusion of a seat cushion enhances user comfort. Furthermore, the frame surrounding the seat allows it to absorb forces and provides support for the user while seated.

[0029] The minimum recording point can be specified, for example, in or on the vehicle floor.

[0030] Mounting and dismounting the seat device can be facilitated if at least one mounting point is located on the side of the support element opposite the vehicle wall, if the seat part, in particular the frame, is rotatably or pivotably fixed on the support element on one side facing the vehicle wall and the other side facing away from the vehicle floor, and / or if the steering element is rotatably or pivotably fixed on one side facing the vehicle wall and below the axis of rotation or pivot of the seat part about the steering axis.

[0031] This means that the support means not only provides the axis of rotation or swiveling around which the seat part can be rotated, but also the mounting.

[0032] Furthermore, the task is solved by a motor vehicle equipped with such a seating device.

[0033] In one embodiment of the motor vehicle, it comprises a vehicle floor, a load-bearing vehicle wall, a seating device with at least one of the aforementioned features and at least one manually movable interior component, such as a table or loading box, which can be fixed or secured in the storage position of the seating device on or in the at least one receptacle of the seating device.

[0034] This makes it possible, when the seat is in its stowed position, to permanently attach other interior components to at least one mounting point. The interior component could, for example, include a storage box in which items or similar objects can be arranged.

[0035] Furthermore, the interior component can include a table that can be secured with at least one table leg in at least one mounting point. It is also conceivable that the table, with its tabletop, rests against the seat section on the side of the seat section facing away from the vehicle floor.

[0036] Further features, details and advantages of the invention will become apparent from the attached patent claims, from the graphic representation and the following description of a preferred embodiment of the motor vehicle.
