Abstract

A central locking system for motor vehicles has all of the opening and closing functions occurring in normal operation also in the event of failure of individual components. If necessary, a vehicle outfitted with this system can also be opened and locked when the door lock motors (50) are out of operation. When the vehicle is locked, the outer door handles (13) can be pulled without meeting resistance and without effect. To this end, a control cam (47) lifts an actuating arm (32) so that a door handle lever (35) can be actuated without the actuating arm (32) being grasped.
