A door lock apparatus, at both sides of a region interposing a second link lever therebetween, includes a sector lever shaft and an inside lever shaft that extend in parallel with a swinging shaft of the second link lever. The door lock apparatus also includes an inside handle lever swingably arranged about the inside lever shaft, and when an inside door handle arranged inside a vehicle is open-operated while the second link lever is disposed in a cancel position, moves the second link lever upwards by swinging about the center of the inside lever shaft, and when the inside door handle is open-operated while the second link lever is disposed in a non-cancel position, swings the sector lever in a locked position to an unlocked position about the center of the sector lever shaft, by swinging about the center of the inside lever shaft.

A door latch device in a motor vehicle comprises an engagement portion including a latch which engages with a striker of a vehicle body. The door latch device comprises an inner lever connected to an inside handle, a lock lever connected to a lock knob on a door inside the vehicle, a subsidiary lever connected to the lock lever, a childproof lock lever, a motor and an actuating member driven by the motor to actuate the childproof lock lever. Childproof locking and a double locking can be carried out by the single motor.

A latch assembly includes a chassis, a latch bolt moveably mounted on the chassis and having a closed position for retaining a striker and an open position for releasing the striker, a pawl having an engaged position at which the pawl is engaged with the latch bolt to hold the latch bolt in the closed position and a disengaged position at which the pawl is disengaged from the latch bolt, thereby allowing the latch bolt to move to the open position, an eccentric arrangement defining an eccentric axis and a pawl axis remote from the eccentric axis. The eccentric arrangement is rotatable about the eccentric axis, and the pawl is rotatable about the pawl axis. When the pawl moves from the engaged position to the disengaged position, the eccentric arrangement rotates in one of a clockwise and a counter-clockwise direction about the eccentric axis. With the pawl in the engaged position, a force applied to the pawl by the latch bolt creates a turning moment on the eccentric arrangement in the one of the clockwise and counter-clockwise direction, and the eccentric arrangement is prevented from rotating in said one of the clockwise and counter-clockwise direction by a moveable abutment.

An electrical circuit arrangement includes an unlatching actuator, a primary power source and a secondary power source. The electrical circuit arrangement further includes an operator actuated switch and an electrically controlled bypass switch having an energized condition at which the bypass switch adopts a first switching configuration and a de-energized condition at which the bypass switch adopts a second switching configuration. The circuit has a first configuration in which the bypass switch is in the first switching configuration so that the primary power source, the operator actuated switch, the bypass switch and the unlatching actuator are configured so that actuation of the operator actuated switch causes the unlatching actuator to be energized by the primary power source. The circuit has a second configuration in which the bypass switch is in the second switching configuration so that the secondary power source, the operator actuated switch, the bypass switch and the unlatching actuator are configured so that actuation of the operator actuated switch causes the unlatching actuator to be energized by the secondary power source.

An automative door latch has, in one invention, a child-safety locking switch (102) using an overcentre spring (110), for exerting extra spring bias on a lock toggle lever (610) operating the interior door lock. In another invention, a mechanical cooperation between the two lock toggle levers (516) operating interior and exterior door locking ensures that manual operation of either handle, when unlocked, to cause the corresponding lever (516) to open the door or other closure, causes the corresponding pawl release assembly (514, 510) to move the other pawl release assembly (514, 510) to its unlocked, pawl-engaging position, if that other pawl release assembly had been at its locked, pawl non-engaging position. In a third invention, a motor drives the latch bolt (2) for closing the door, through two (907, 908) segment gears which mesh for only part of the turning movement of a rotary driving and indexing mechanism (906) which also operates door opening and locking. In a fourth invention, rotary drive sequence control for a rotary driving and indexing mechanism (906) is provided by a cam guide (930) and cam frame (950), the guide having endwalls and a central stop, the cam guide being shaped in the region of the end walls to guide the cam member in a unique direction through a unique loop relative to the cam guide, such that when the cam member is released from the central stop it is moveable to either end wall and then only to the central stop and not directly to the opposite end wall.

An improved electric latch including latch position registration at power loss. A small motor affects a number of independent electrical actuations using an index gear, actuations of: Central Locking, Super Locking, Selective Locking, Power/electrical door opening (Passive Opening), and Power/electrical door closing (Soft Closing). The improved latch uses at least one sensor and several targets positioned on latch hardware to register drive mechanism positions of a latching system after loss of power. The improved system uses a sensor and target specifically for registered function. The present invention avoids the complexity of prior Latch designs by providing for latch position registration.

Motor vehicle lock with a ratchet, latch, actuation lever, internal actuation chain, external actuation chain and a control, the ratchet having an engagement position in which it holds the latch in the closed position, and a raised position in which the latch is released, the ratchet being movable from the engagement position into the raised position by the actuating lever, the control having different operating states and depending on the state, the ratchet is actuatable via the actuation lever by the internal actuation chain from an inside door handle and/or by the external actuation chain from an outside door handle or not at all. In the base state, the internal actuation chain and the external actuation chain are coupled to the actuation lever and the internal actuation chain and/or the external actuation chain can be decoupled from the actuation lever by the control depending on the operating state.

A latch of a vehicle includes a displacement member having a first position, a second position, and an intermediate rest position and an output movable between a first output position and a second output position. A first mode of operation is possible where the output lever is driven between the first output position and the second output position by a stepper motor and a second mode of operation is possible where the output lever can be moved between the first output position and the second output position independently from the stepper motor. A common control controls all the latches in the vehicle.

An automobile vehicle lock is released under normal operating conditions by an electric motor. Under degraded conditions, a mechanical release of the lock is enabled. This allows the motor providing electrical release of the lock to be simply dimensioned for release under normal operating conditions with no requirement to over-dimension the motor to ensure the lock will open under degraded operating conditions. Because release of the lock is mechanical under degraded operating conditions, enablement of the mechanical release is provided by a low-power standby motor. This allows a compact and inexpensive standby power source to be employed.

A door latch arrangement (10) includes a latch bolt (12) releasably retainable in a closed position by a pawl (14). The pawl is connected to an inside release member (26) by a first transmission path (28). The first transmission path is interruptible by operation of a first actuator (32). The pawl is further connected to an outside release member (16) by a second transmission path (18), the second transmission path being interruptible by operation of a second actuator (22). The door latch arrangement further includes a detection device for detecting when the inside release member is operated. The first and second actuators are controlled by a control device (36), operable in response to signals from the detection device to provide for override unlocking.
