Abstract: A linear drive, particularly useful for locking or unlocking a door lock mechanism or the like permits manual operation by providing an output shaft that can move freely regardless whether the output shaft is in extended or retracted positions without back driving the motor. The output shaft is coaxially slideably situated over a screw which moves a nut that is theadingly engaged therewith and moves inside the output shaft along the axial direction of the screw. The output shaft is not threadingly engaged with the screw. The output shaft thus is freely movable relative to the screw, which results in essentially zero back drive of the screw and the motor. To provide for manual operation, the nut is automatically moved back to its neutral position every tie the output shaft is extended or retracted by a torsion spring or the like which can store energy therein. Whenever the motor is operated to drive the screw, the spring gear is also rotated, which causes the spring to store energy therein.

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.

Abstract: Door lock and lock assemblies are useful, for example, in vehicle cabs. Latch and lock assemblies of known structures which can be unlocked from inside the cab while remaining locked from outside the cab require complex and bulky linkage assemblies. The subject door latch and lock assembly includes pivotal outer and inner actuator. The pivotal movement of the outer actuator simultaneously pivots the inner actuator to open a catch mechanism. Pivot movement of the inner actuator can be independent of the outer actuator. A locking lever can be pivoted to a locked position to prevent pivotal movement of the outer actuator. Pivotal movement of the inner actuator is not prevented by the locking lever. Thus, the disclosed door latch and lock assembly can be opened from inside the cab while remaining locked from outside the cab without requiring complex and bulky linkage assemblies.

Abstract: A vehicle door lock (106) and latch (104) assembly is provided whereby a key may be used to lock the door (100) and to prevent rotation of the outside door handle (108). A lock handle (116) is provided inside the vehicle door (100) for overriding the key lock (110) to permit the inside and outside handles (114,108) to operate to open the door. Both the key lock (110) and the lock handle (116) when turned operate a linkage (172,168) which is connected to the locking cam (158) enabling the locking cam (158) to be moved between its locked and unlocked positions. Even with the lock handle (116) and the key lock (110) in the locked position, the inside handle (114) can be turned to move the locking cam (158) to the unlocked position and to open the door (100). The outside handle (108) can now be used to open the door also. The outside handle (108) can also be released for operation by turning the key in the key lock (110) to the unlocked position.

Abstract: A central vehicle door-lock system has several door latches each including a detent movable between a lock position securing the door closed and an unlock position allowing the door to be opened by means of a mechanism inside the door latch.
