A system for locking the doors of a vehicle by central command includes a reversible motor driving a worm gear. A traveling nut operated by the worm gear engages a lock-actuating lever through an overload clutch. The overload clutch includes a cam and a cam follower. The cam has a normal central stable position bounded on either side by regions of neutral stability which permit override by small manually applied forces in case the motor or worm gear malfunctions. The system further includes a spring powered mechanism for unlocking the doors in the event of an accident. The spring powered mechanism is tripped electrically by an acceleration-sensing switch, and can be recocked by applying a relatively large force to a plunger located on the window sill.
