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.

Actuator for a vehicle seat, and vehicle seat

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 () establishes the actual value of the height of the seat frame. The adjuster () has a cable roll () 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 (), which can be at least partially wound on the cable roll (), 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 () of the pneumatic spring in accordance with a desired value of the height of the seat frame. A gear mechanism () creates an operational connection, in particular a gear connection, between the cable roll (), a desired value generator (), by which the desired value of the height of the seat frame can be adjusted, and a control device () which controls the at least one control valve ().

Vehicle seat, in particular utility vehicle seat

In an adjuster () for a vehicle seat, in particular for a motor vehicle seat, having at least two components () forming a load-bearing gear, which are movable relative to each other by way of a drive unit (), wherein the drive unit () has a particularly electronically commutated motor () and a gear stage (), the drive unit () is integrated into the load-bearing gear, and the motor () has at least one rotor () borne in the load-bearing gear and rotating around an axis (A).

Adjuster for a vehicle seat

In a drive unit () of an adjuster () in a vehicle, having at least one particularly electronically commutated motor () and at least one gear stage () provided on the output side of the motor (), the gear stage () is designed as a differential gear, which by making use of two different speeds and/or directions of rotation causes a movement of an output () around an axis (A).

Drive unit of an adjuster in a vehicle

In a drive unit () of an adjuster () of a vehicle seat, in particular of a motor vehicle seat, having at least an electronically commutated motor () and a gear stage () provided on the output side of the motor (), wherein the motor () has a stator () and at least one rotor () rotating around an axis (A) and interacting magnetically with the stator (), two rotors () are provided which rotate in different directions, wherein the gear stage () bears directly at least one rotor ().

Drive unit of an adjuster of a vehicle seat

In a drive unit () of an adjuster () of a vehicle seat, in particular of a motor vehicle seat, having at least one particularly electronically commutated motor () and at least one gear stage () provided on the output side of the motor (), the gear stage () is designed as a differential gear, which by making use of two different speeds and/or directions of rotation causes a movement of an output () around an axis (A).

In a drive unit () for vehicle seat, in particular for a motor vehicle seat, having at least one motor () and at least one gear stage () provided on the output side of the motor (), the gear stage () is designed as a switch gear, so that two different directions of rotation of the output () can be provided/selected between, while retaining one sole permanent direction of rotation of the motor ().
