In order to electrically reverse the motorised pivoting actuator, used for example to adjust an exterior mirror with restricted angles of movement and to return the mirror into a working position after it has been pivoted by external means (either by hand, or as a result of a collision), the engagement of the coupling actuator is axially detached, as a result of an external pivoting of the coupling output drive, against an elastic restoring force and the coupling output drive is pivoted in relation to the coupling actuator, according to the effective torque. Thus, the coupling output drive is also brought out of its restricted trajectory, in such a way that the drive motor (13) can rotate the coupling actuator (16) freely, until the coupling actuator and the coupling output drive reach a relative position, which has been predetermined in the construction concept. In said position, the coupling claws (28) re-engage in their opposing recesses. The motor then rotates the mirror, until the coupling actuator is brought out of its unrestricted orbit and is returned to the trajectory with restricted angles of movement. The mirror (22) can then once again be pivoted in a motorised manner about its previous working position. |
