Abstract
This actuator comprises in combination an electric motor (1) capable of driving in rotation a screw (2) which shifts a nut (6) which positively drives a carriage (7) in the direction for rendering the latch operative and, through a spring (8), in the direction for rendering the latch inoperative, the carriage (7) driving an output lever (9) connected to the interior lever for rendering the latch inoperative; a pivotal cam (10) having cam surfaces along which is slidable a control stud (14) connected to the nut (6). This cam controls a connecting kinemative system (11, 12) connected to the interior lever for rendering the latch inoperative, on one hand, and to the exterior lever controlling the opening of the latch on the other hand, through means outside the case of the actuator. This anti-theft system permits unlocking the latch normally by means of a key from the anti-theft position in the event of a breakdown in the electric supply.
