Patent number: 5453671Abstract: 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.Type: GrantFiled: May 13, 1993Date of Patent: September 26, 1995Assignee: SWF Auto-Electric GmbHInventors: Joachim Baier, Udo Baumeister, Heiner Bayha, Uwe Fortwingel, Ronald Frey, Rainer Johannsmeier, Heinz Leiter, Dieter Losch, Rudolf Watzka
