Abstract: A locking device for vehicles, particularly for vehicle doors has a mechanical revolving connection between a cylinder core of a lock cylinder and a safety lever of an assigned lock which comprises a driving coupling in the form of a lock nut. In order to achieve a simplification of the construction and mounting of the locking device while ensuring the operability of the locking device when it is operated mechanically as well as when the central locking system is operated, the lock nut is constructed in one piece. An end side of the lock nut facing an operating lever arm of the safety lever has two stops spaced angularly from one another and projecting from the end side. The operating lever arm engages between the stops, so that when the lock nut is rotated, a locking or unlocking position of the safety lever is achieved after an idling path.

Abstract: A set/operate mode switch is interposed between the door sensing or element door position activated switch and a remote monitoring station, to enable the remote station to monitor the door condition, or to enable a local signal assembly to monitor the door condition. The local signal assembly is made operative by the set/operate switch, so that the sensing element can be accurately set before turning door monitoring over to the remote station. While the local signal assembly is verifying the door condition, a shunt or shorting element keeps the remote monitoring station displaying a door open condition, all the while that the local signal assembly is operatively engaged, for security reasons. Only when the local signal assembly is isolated from the arrangement, can the remote monitoring station give a true signal of the door condition.

Abstract: After a door is super-locked by an electric motor, the door cannot be unlocked by a manual control knob for passenger's safety and for burglarproof. The door-lock unit and other components including the electric motor and a door-lock unit are protected from a violent force applied on the knob or some other components even if an inappropriate attempt to open the door in such occasion. In the actuator, an output lever which is connected to the door-lock unit rotatably disposed on an input lever which is connected to the knob. A clutch lever is connected to the torque transmitting mechanism and is rotatably disposed on the output lever. When the door is super-locked, the output lever is retained by a stopper, and only the clutch lever is rotated counterclockwise so that the clutch arm disengages from the input lever. As a result, even if the knob is drawn forcibly to unlock the door, only the input lever is rotated as the knob is moved and no violent force is applied on the door-lock unit or the electric motor.

Abstract: The invention relates to an electromotive actuator with a housing for a central door locking system of a motor vehicle having a first slide adjustable by a first electric motor between two end positions. The first slide can be connected with a door lock of the motor vehicle independently of the end position and is preferably decoupled from the electric motor in the end positions, so that the first slide is manually adjustable between its end positions. Such an electromotive actuator is provided with a theft protection capability in the sense that, after a windshield of a motor vehicle is smashed in, an unlocking of the door by the inside locking handle is no more possible because the parts of the actuator are not actuated by operating the inside locking handle. Finally, an unlocking operation initiated from the outside is possible when the theft protection is put into operation.
