The invention relates to a device for adjusting a vehicle seat in the longitudinal direction, said seat comprising a freely pivoting back rest. The inventive device comprises a first seat rail, a second seat rail in relation to which the first seat rail can be displaced in the longitudinal direction, and a memory element which is associated with the first seat rail and interacts with the second seat rail. Said memory element is used to store an adjusted longitudinal position of the seat, the seat leaving said longitudinal position when the back rest is pivoted, and returning to said position when the back rest is pivoted in the reverse direction. The inventive device also comprises a displacement sensor (21) which can interact with the second seat rail, and a control signal emitter (41) which can be displaced in relation to the displacement sensor (21), the relative movement of said signal emitter in relation to the displacement sensor (21) reproducing, from a starting position, the longitudinal displacement carried out. The control signal emitter (41) is subjected to a control torque, at the latest once the stored longitudinal position of the seat has been reached, and then controls at least one blocking element (73) which interacts with the second seat rail by means of a control spring (51). A control area (45) is arranged between the control signal emitter (41) and the control spring (51), which guides the control signal emitter (41) and which stores the control spring (51). |
