Abstract: An actuator for a vehicle seat has a housing, a motor with a motor shaft which has at least a first direction of rotation, a gear mechanism which is connected at the output end to the motor by the motor shaft, an actuator output drive which is connected at the output end to the gear mechanism, and a control unit. The actuator output drive has an output element which can be moved in the direction of an end position from a starting position by rotation of the motor shaft in the first direction of rotation. The direction of rotation of the motor shaft can be reversed from the first direction of rotation to an opposite second direction of rotation by the control unit, with the result that the output element can be moved in the direction of the starting position from the end position.

Abstract: A device for controlling and/or regulating the electromechanical actuator of a planetary gear assembly includes commutation electronics that are designed as an electronic circuit board and are arranged in a housing, directly on a solenoid ring of the electromechanical actuator. The housing accommodates the planetary gear assembly and the device that electromagnetically actuates the same. The solenoid ring is formed by annular solenoids that can be actuated in turn in the circumferential direction of the solenoid ring by the commutation electronics.

Abstract: A vehicle seat, in particular a utility vehicle seat, has a seat frame which can be pivoted by a pneumatic spring and which can be adjusted in terms of height. An adjuster (20) establishes the actual value of the height of the seat frame. The adjuster (20) has a cable roll (22) which is supported on a first portion of the seat frame so as to be able to be rotated about an axis (A), and a cable (24), which can be at least partially wound on the cable roll (22), unwound therefrom and is secured to a second portion of the seat frame that can be moved relative to the first portion, and which controls at least one control valve (36) of the pneumatic spring in accordance with a desired value of the height of the seat frame.

Abstract: A drive unit (10) for an adjuster in a vehicle, in particular for a vehicle seat, has at least one motor (12) which has a stator (16) with at least one coil (24). At least one rotor (18) which interacts with the stator (16) in a magnetic manner, rotates about an axis (A) and is fitted with permanent magnets. A commutation module (20) is provided for supplying current to the coil (24) as a function of the rotation of the rotor (18). An electrical connection (22) is provided for an at least two-pole supply voltage (+Ub, ?Ub). The commutation module (20) is selected from a set of brush-commutating and brushless commutation modules (20), with the structure of the motor (12) otherwise remaining the same.
