Abstract
Official abstract text for this publication.
A motor and a gear unit form an actuator. The gear unit is fitted with at least two mutually movable gear parts, acted on by a spring that counteracts their movement out of an idle state. The gear unit is fitted with at least one manual actuator that when actuated switches the motor off, disengages two mutually interacting gear wheels of the at least two gear parts and forces the at least two gear parts into the idle state. When the motor moves the gear parts out of the idle state during operation to an operating point, a cam plate on a first gear part is contacted by a sensor element on a second gear part, and the spring acts on the first and second gear parts during the movement out of the idle state in accordance with a position on the cam plate of the sensor element.
