Abstract

An actuator (110, 210) for a vehicle seat (1) includes a housing (11), a motor (12) which is fixed to the housing and includes a motor shaft (12a), a transmission (13) connected to the motor shaft, an actuator output drive (14) which is connected to the transmission, and a control unit (21). The actuator output drive includes an output element moveable towards an end position from a starting position by rotating the motor shaft in a first direction and in a reversed direction—in the direction of the starting position from the end position. A carriage (15) is driven, upon movement of the output element. A position sensor detects a position of the carriage. An actuator (210) for a vehicle seat is provided, in which a position sensor (28) detects an effect of gravity on the actuator. A vehicle seat (1) with one such actuator (110, 210) is provided.
