Patent ID: 7140683

Claim:
Motor vehicle seat comprising: a seat frame; a backrest mounted pivotally on the seat frame and movable into an upright position and a forward position folded toward a seat surface of the seat frame; a longitudinal guide along which the seat frame is movable in a seat longitudinal direction for adjusting a seat longitudinal position; a fixing device adapted to adopt a locked configuration for locking the seat frame in a seat longitudinal position along said longitudinal guide, said fixing device further adapted to adopt a fully released configuration for releasing said seat frame from said seat longitudinal position; an operating element adapted to unlock the fixing device thereby rendering the seat frame movable from the seat longitudinal position in the seat longitudinal direction to allow adjustment of the seat longitudinal position; a coupling mechanism movable together with the seat frame in the seat longitudinal direction, the coupling mechanism configured to act on the operating element to unlock the fixing device when the backrest is folded toward the forward position; a memory device to stop the seat frame during movement in the seat longitudinal direction at a predeterminable memory position; adjusting means for the memory device configured to adjust the memory position in the seat longitudinal direction; a locking device for locking the memory device in a set memory position; and a first engagement element coupled to and movable by the coupling mechanism and a second engagement element provided on the memory device, the engagement elements adapted to be brought into engagement with each other upon exertion of a force on the operating element in order to unlock the fixing device, the engagement elements further adapted to be in engagement with each other to prevent adjustment of the seat longitudinal position in the seat longitudinal direction while a) the seat frame is located in its predetermined memory position, b) the memory device is locked by the locking device, and c) the fixing device is out of the locked configuration and approaching the fully released configuration so as to not prevent adjustment of the seat longitudinal position in the seat longitudinal direction.
