A vehicle seat has a sitting surface and a backrest which has a backrest upholstery with a forward upholstery arching arranged in the region of the lumbar vertebrae of the seat user for the purpose of relieving the user's intervertebral discs. For the physiologically most efficient back support for seat users of widely varying body height, without the need to carry out individual adaptation measures on the backrest, the upholstery arching is configured such that its contour vertex is located approximately 250 to 275 mm above the sitting surface and here is itself made so flexible that it easily matches the shape of the back of the seat user, and a relatively rigid pelvic support is formed in the upholstery arching approximately 150 to 175 mm above the sitting surface.

Vehicle seat

In a tilt-adjustable seat cushion for a vehicle seat having an underframe receiving the upholstered seat part, two lateral frame parts for the pivotable bearing of the underframe and a tilt-adjusting mechanism operating between the underframe and the frame parts for the individual adjusting of the front edge of the seat, the manually operated adjusting shaft of the tilt-adjusting mechanism, in order to facilitate the assembly, is disposed in a separate bearing block that, after pre-assembly with the frame parts and the adjusting shaft, is connected with the underframe by screws or clips.

Tilt-adjustable seat cushion for a vehicle seat

A rear headrest adjusting arrangement in a motor vehicle has a headrest pivot bearing unit that is fixed at the seat and at which two head pad holding devices are disposed that are spaced away from one another in the direction of the pivotal axis. A pivot bearing shaft is provided that has two connecting parts for the holding devices, the connecting parts being spaced away from one another and being connected with the pivot bearing shaft in a torsionally fixed way. A driving motor is provided adjacent to the pivot bearing shaft, the driving motor having a motor shaft that with respect to its axis is parallel to the pivot bearing shaft and having a gearbox that connects the motor shaft with the pivot bearing shaft. This provides the possibility of a motor-driven headrest adjusting arrangement with little installation space for the pivot bearing unit.

Headrest adjusting arrangement, particularly in a motor vehicle

In a vehicle seat having a seat cushion subdivided, for set depth adjustment, into individual upholstery elements in the transverse direction of the seat, the individual upholstery elements are connected together by a coupling mechanism. The coupling mechanism is designed so that each of the gaps appearing between the upholstery elements when the depth is adjusted has the same gap width, and the upholstery elements, after conclusion of the set depth adjustment, are fixed in their particular adjusted position.
