ABSTRACT:
An apparatus is disclosed for electrically locking the doors of motor vehicles, wherein at least one motor is supported in a driver door and the motor is coupled with a lock mechanism by means of a connecting element, with a first switch coupled with the motor to be actuated thereby and a second switch coupled with the lock mechanism to be actuated thereby and also coupled with the first switch and with the motor, and the switches are connected with at least one additional motor coupled with a further lock mechanism. Structure is included to change the direction of the force exerted by the motor on the lock mechanism, for locking or unlocking the doors, respectively. The invention is characterized in that both the first switch and the second switch are arranged in a structural unit or housing attached to the motor, which housing contains an activating mechanism with activating elements to activate the first and second switches, the activating elements being part of a gear train forming a force flow path between the motor and the connecting element, and the gear train being constructed to reverse the direction of movement of the connecting element in dependence on the rotation completed by the motor. The connecting element is coupled with the motor by means of a lost motion connection via the activating element of the second switch.
