Abstract

A motor-vehicle latch has an actuating lever displaceable between a position in which a respective door of the vehicle is locked and a position in which the respective door is unlocked. A locking knob connected to the lever is accessible from inside the vehicle to displace the lever between its positions. The actuator has a housing mounted directly on the door latch and formed with at least one longitudinally directed abutment face, a motor in the housing, a nut longitudinally displaceable in the housing by the motor between unlocked, locked, and antitheft positions, and a slide in the housing movable by the nut between locked and unlocked positions and formed with a recess receiving a portion projecting from the lever. At least one flexible arm extends longitudinally from the slide and has a head formed with a face directed longitudinally opposite the abutment face of the housing. These faces longitudinally confront but are out of longitudinal line with each other in the locked positions of the slide and nut. An actuating formation on the nut is engageable with the arm for laterally elastically deflecting the arm on displacement of the nut from the respective locked to the anti-th…
