Abstract: The present device generally relates to a seat for a motor vehicle. The seat includes a back rest, seat cushion, and an arrangement for hingedly connecting the back rest with the seat cushion. The connecting arrangement includes an arrangement for producing a rotary movement which takes place optionally starting from a neutral position of a lever into either of two directions of rotation. Essentially, a shaft is only turned by way of the lever so long as the drive lever is moving away from the neutral position whereas, when the drive lever is swivelled towards its neutral position, the shaft is essentially not entrained. Cooperating elements exert different forces on the shaft.

Abstract: 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.

Abstract: A seat longitudinal adjusting mechanism for a motor vehicle seat with a guide rail unit consisting of two rails enclosing therebetween a hollow space and longitudinally displaceably supported at one another. A toothed rack connected with one rail extends within the hollow space, into which engages a pinion supported in a pinion cassette. The pinion is driven by an adjusting gear. For facilitating the assembly, a preassembly rail extending in the rail longitudinal direction is provided which includes fastening means for fastening the pinion cassette at the preassembly rail, independently of the rails, whereby the length of the preassembly rail is essentially equal to the distance of the pinion cassette from one end of the other rail. The preassembly rail preassembled together with the pinion cassette can then be inserted correspondingly into the other rail.
