The invention relates to an actuator (110, 210) for a vehicle seat (1), comprising a housing (11), a motor (12) which is fixed to the housing and which comprises a motor shaft (12a), a transmission (13) which is connected at the output side to the motor (12) by means of the motor shaft (12a), an actuator output drive (14) which is connected at the output end to the transmission (13), and a control unit (21). Said actuator output drive (14) comprises an output element (14b) which can be moved in the direction of an end position from a starting position by rotating the motor shaft (12a) in the first direction of rotation. The direction of rotation of the motor shaft (12a) can be reversed from the first direction of rotation to an opposite second direction of rotation by means of the control unit (21), such that the output element (14b) can be moved in the direction of the starting position from the end position. A carriage (15) can be moved with respect to the housing (11), said carriage can be driven, during a movement of the output element (14b), from the starting position in the direction of the end position, and a position sensor for detecting at least one position of the carriage (15) is provided. The invention also relates to an actuator (210) for a vehicle seat, in which a position sensor (28) is provided to detect the effect of the gravity on the actuator (210). The invention also relates to a vehicle seat which comprises at least one claimed actuator. |
