Actuator for a vehicle seat, and vehicle seat
First Claim
1. An actuator for a vehicle seat comprising:
- a housing;
a motor arranged fixed to the housing having a motor shaft, which has at least one first rotational direction;
a gear mechanism which is connected on the output side to the motor by the motor shaft;
an actuator output drive which is connected on the output side to the gear mechanism; and
a control unit,wherein the actuator output drive has an output element which is able to be moved from an initial position into an end position by rotating the motor shaft in the first rotational direction,wherein the rotational direction of the motor shaft is able to be reversed from the first rotational direction into an opposing second rotational direction by the control unit, so that the output element is able to be moved into the initial position from the end position,wherein at least one first sensor detects the end position of the output element,wherein the control unit has a sensor interface which is connected to the at least one first sensor, andwherein an identification of the position of the output element is provided by evaluation of changes in measurements of time and at least one of current and/or voltage.

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.
