Abstract: A seat cushion adjustment for vehicle seats, more particularly the seats of motor vehicles, depends on the adjustment path of at least one main adjustment of the seat and serves for adapting the development curve of the seat cushion adjustment individually and ergonomically. The seat cushion adjustment includes a first adjustment for a main adjustment of the vehicle seat within a defined adjustment area, and a second adjustment coupled to the first adjustment for adjusting the seat cushion in dependence on a main adjustment of the vehicle seat. The seat cushion adjustment also includes a separate adjustment coupled to the first or second adjustment for fixing the development curve of the seat cushion adjustment within a restricted adjustment area, whereby the extreme positions of the seat cushion are associated with the extreme positions of at least one main adjustment of the vehicle seat.

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.
