Abstract

An actuator for a motor vehicle has a drive motor, an actuating element and a blocking element. The blocking element can be deflected by the actuating element, against pretensioning, into a blocking position in which the blocking element blocks further movement of the actuating element. For this deflection, the blocking element is equipped with a tappet and the actuating element is equipped with a power transmission element. The actuating element is equipped with a stop and the blocking element is equipped with an counter-stop for blocking. Before the blocking is produced, the power transmission element releases the tappet, and after release, the blocking element, driven by its pretensioning, causes its counter-stop to fall onto the stop of the actuating element in a catch position.

Claims22

Dependent claims

Actuator in a motor vehicle, comprising:

a drive motor,
a rotary actuating element with a power transmission element thereon and which is driven by the drive motor in actuating cycles, and
a pivoting blocking element which is pre-tensioned into an initial position, the blocking element having a tappet which engages the power transmission element during an actuating cycle so as to be moved in a direction toward a blocking position and a counter-stop which engages a stop on the actuating element during continuation of the actuating cycle, thereby blocking further movement of the actuating element, and during the actuating cycle and before blocking of the actuating element, the power transmission element releasing the tappet, and the blocking element, unhindered by the power transmission element, being able to pivot toward said initial position,
wherein, after release of the tappet and before blocking of the actuating element, the blocking element, driven by its pretensioning, engages the counter-stop onto the stop of the actuating element in a catch position.
