Abstract: A vehicle door locking system comprises a control portion for performing control operations of changing positions of lock levers into locking positions and of changing positions of anti-theft mechanisms into anti-theft positions. The control portion causes sending means to send out a warning signal for a predetermined time period, when a faulty change in position of the lock levers or the anti-theft mechanisms occurs. If a key cylinder or a transmitter is operated during the signal is sent out, the warning signal is stopped even before the predetermined time period has elapsed.

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: A tailgate handle assembly in a housing including a flush-mounted handle and an adjacent key cylinder. The housing is spaced apart from a tailgate latch mechanism.

At least one flexible arm extends longitudinally from the slide and has a head formed with a face directed longitudinally opposite the abutment face of the housing.

Abstract: A motor vehicle door lock is equipped for cooperation with a central locking system able to lock all doors of a vehicle from a single control. The lock also has a pull closed mechanism which is driven by the same motor driving the locking elements in response to a signal from the central locking system. The pull closed mechanism cooperates with a fork latch for bringing the fork latch from a preliminary latching position into a main or final latching position, whereby door slamming for properly closing a vehicle door is not necessary. It is now sufficient if the user closes the door so that the fork latch is in its preliminary latching position since the present invention mechanism will then close the vehicle door completely.

Abstract: A centralized door-locking system in a motor vehicle in which all of the doors of the vehicle and a tailgate of the vehicle have lockable latches which can be locked/unlocked electrically using key-operable switches asociated with the lockable latches in the driver's door, front passenger's door and the tailgate of the vehicle. In the system, it is possible to selectively lock/unlock the driver's door and/or the tailgate independently of the remaining doors of the vehicle, thus improving the overall security against unauthorized entry to the vehicle by third persons during usage of the vehicle. This selective locking/unlocking of the driver's door and tailgate may be achieved by using, for example, a key-operable switch in the driver's door having a rotatable key barrel 32 with key slot 160 which is rotatable clockwise or anticlockwise from a central position N to sequential switching positions A and B, or C and D, against an increasing spring bias 162, 164.

Abstract: An electric door lock system is disclosed which comprises an electric actuator which moves an output member in first and second directions selectively, a door locking mechanism which moves a latch plate of a door lock device proper from its half-latched position to its full-latched position when the output member is moved in the first direction, a lock cancelling mechanism which cancels the locked condition of the latch plate when the output member is moved in the second direction, a lock cancelling switch means incorporated with an inside or outside handle of the door, which operates in response to manipulation of the handle, a locking and unlocking switch means which operates when locking and unlocking of the door are required, a half-latched condition sensor which senses that the latch plate has come to the half-latched position from its open position, and a control means which functions so that when, with the door lock device proper being in its unlocked condition, the lock cancelling switch means is mani

Abstract: The disclosure is concerned with an electrically operable central locking and unlocking device for vehicle doors with mechanical locks at each door or lid, and with electromechanical actuation for such door locks in which the actuation is transferred by a vertically movable actuating rod capable of moving between an unlocked position and a locked position, to a control rod of the associated door lock. The device includes a reversible electric motor, a transmission, and an actuating mechanism for the actuating rod. The device also includes exterior ridges on a spindle-nut and projecting formations which serve to carry along the actuating rod during the lock stroke and during the unlocking stroke. The ridges can override, after completion of the lock stroke, as well as after completion of the unlock stroke, the projecting formations.

Abstract: An automotive vehicle having no pillar between adjacent front swinging and rear sliding doors is provided a structure for mounting a front door striker engageable with a door lock of the front door. The door striker is mounted on a vehicle side sill with a reinforcement which provides sufficient stiffness for the vehicle side sill for resisting against bending stress applied thereto. A guide rail retainer secured to an inner wall of the side sill supports an end of a guide rail for the sliding rear door.

Abstract: A lever for controlling a lock of an automobile door is mounted on the door and projects from the door. A shield is fixed to the door, and lies parallel to and inward of the lever so that the lever lies behind the shield as seen from the automobile passenger compartment. The shield extends forward of the free end of the lever to prevent access to the control lever when the door is in its closed position.

Abstract: The central locking installation for motor vehicle door locks blocks the locking element of the door lock by means of an additional, separately controllable blocking member. The locking element and the blocking member are driven by separate electrical drives which are connected into mutually parallel-connected current paths of one common drive current circuit. The drive direction of the two drives is controlled by common switches of a pole-changing circuit which reverses the current direction. Into the current path of the drives of the blocking member there is connected a control switch by way of which these drives can be switched on selectively. In the unlocking direction and the unblocking or releasing direction a time control system controllable by means of the door key in the unlocking of the door switches on the drives of the locking element and of the blocking member simultaneously. In the locking of the door lock only the drive of the locking element is switched on in its locking direction.

Abstract: A door lock arrangement for a vehicle in which there is no pillar against which the trailing edge of a forwardly hinged door may engage, includes locks provided at the top and bottom corners of the door and a centrally located mechanism for simultaneously operating said locks. This mechanism includes means for producing both of the so called "keyless locking" and "self cancellation" functions.

Abstract: A remote control door-lock device connected to front and rear door lock devices for an automotive vehicle used to lock/unlock the front and rear vehicle doors from a position near a driver seat comprises one or two guide plates having a slot formed therein and one or two actuation members having projection pins on one side thereof and an opening on the other side thereof. The guide plates are controlled by a remote control lever via a cable, and the slots thereof engage the pins so that the guide plates control the position of the actuation members, but with some mutual free travel. The actuation members also engage with front and rear door lock members, usable by passengers, so that if the remote control lever is actuated, the door lock members are in turn actuated to lock the respective doors, and to disable the door lock members. That is, the door lock members can be actuated either directly or by the remote control lever.

Abstract: A central door-lock system has a plurality of door latches each including a detent displaceable between an open position securing the respective door to the respective doorpost and a closed position permitting the respective door to separate from the respective doorpost, a manual door-opening handle, mechanism including a primary latch member connected to the handle and connectable to the detent and movable between a lock position preventing this handle from displacing the detent between its open and closed positions and an unlock position permitting the handle to displace the detent between the open and closed positions, and a secondary latch member displaceable between a lock position urging the primary latch member into the respective lock position while permitting the primary latch member to move into the respective unlock position, an unlock position permitting the primary latch member to move freely between the respective lock and unlock positions, and an antitheft position positively holding the primar

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. Each of these latches is associated with a servoactuator having an actuator that is engaged via this mechanism with the respective detent and that is in turn moved by an operator. This operator, therefore, can move the actuator and with it the latch detent between lock and unlock positions, and the operator itself is movable by a servomotor into an antitheft position. A lock pawl on the actuator can, in the lock position of the actuator and in the antitheft position of the operator, move from a freeing position permitting displacement of the actuator from the lock to the unlock position into a blocking position preventing such displacement to lock up the entire latch.

Abstract: An articulated linkage locks the various access panels, covers, and plates opening into an engine and its accessories. A spring loaded shaft is used to drive a bell crank and a set of catch bolts. Each catch bolt is matched with a catch plate joined to one of the panels, covers and plates granting access to the engine and its components. A pair of doors covering the instrument panel is used to reposition the spring loaded shaft and bell crank. Locking the doors together therefore locks the catch bolt and catch plates together in one stroke and with one lock.
