A door lock system includes a first link lever, a second link lever, and a spring. The first link lever moves to a transmitting position in response to an unlocking operation. The second link lever includes a ratchet driver that is formed integrally with a bushing. The ratchet driver is rotatable between a first rotational position and a second rotational position on the first link lever. In response to a door-opening operation, when the ratchet driver is in the first rotational position and the first link lever is in the transmitting position, the second link lever allows a ratchet lever to disengage a ratchet from a latch. The spring maintains the second link lever in the first rotational position when the first link lever moves to the transmitting position.

In one aspect, the invention is directed to a closure latch for a vehicle door. The closure latch includes an emergency lock actuator to permit a person to lock the door in the event that the power lock actuator is unusable. The latch also includes an ‘impatient passenger’ feature, which permits the doors to be unlocked using the remote keyless-entry feature on the key fob even in a situation where an ‘impatient passenger’ had prematurely lifted the door handle of the vehicle. In some prior art latches, such an action by an ‘impatient passenger’ would prevent the drive motor on the latch from unlocking the latch, thereby necessitating the owner to press the unlock button on the key fob a second time. There is some overlap in the components that used for the ‘impatient passenger’ feature and the components used for the emergency lock actuator, thereby reducing cost and complexity of the latch.

A door lock apparatus for a vehicle includes a latch mechanism, an open operation lever, an open lever operatively connected to the open operation lever, a locking lever being switchable between an unlocked position and a locked position, a link operation lever operatively connected to the locking lever, a link member operatively connected to the link operation lever, the link member being able to transmit an operation of the open lever to the latch mechanism when the locking lever is in the unlocked position, the link member being unable to transmit the operation of the open lever to the latch mechanism when the locking lever is in the locked position, and a lever member operatively connected to the open lever and the locking lever, the lever member moving the locking lever from the locked position to the unlocked position by means of the operation of the open lever.

A vehicle door opening / closing device having a latch mechanism, a locking mechanism, an actuator, and a canceling mechanism is provided. The actuator has an electric motor and a pivotable drive lever. The canceling mechanism operates to block transmission of power between the electric motor and the drive lever when manipulation force of a vehicle door handle is transmitted to the canceling mechanism through the locking mechanism. The manipulation force of the door handle is transmitted to the canceling mechanism only when the vehicle door is in an unlocked state.

A door operating device is provided in a door of a vehicle and connected to a door latch allowing a striker of the vehicle to engage with or disengage from the door latch. The door operating device comprises an outside lever, a release lever under the outside lever and a locking lever connected to an actuator. In a locking position, only the outside lever rotates, while both the outside and release levers rotates in an unlocking position. The locking lever comprises first and second lever portions which separately move. If malfunction occurs, the second lever portion is moved by an actuator.

[Problem] To provide a door locking device for a vehicle, wherein it is possible to reduce production costs while preventing the door from opening unintentionally when the vehicle is in a collision and while eliminating having to redo an unlocking operation when the unlocking operation and a door opening operation overlap. [Solution] A door locking device (1) for a vehicle, wherein: a third lever (50) is capable of being displaced to a third position and a fourth position, the third position being a position in which a second lever (30) capable of swinging from a first position to a second position as a consequence of an inertial force (F1) surpassing a set value and acting on the second lever (30) is allowed to be at the first position and the second position, and the fourth position being a position in which the second lever (30) is held at the second position; and a fork (11) can be switched to an unlatch state when the third lever (50) is at the third position, while the fork (11) cannot be switched to the unlatch state when the third lever (50) is at the fourth position. When a first lever (13) attempts to swing while the second lever (30) is at the second position, a holding means (60) allows the first lever (13) to swing while holding the second lever (30) at the second position regardless of the position of the third lever (50).

This invention relates to a door latch system. The door latch system includes: a housing; a latch pivotally and rotatably installed in the housing; a main locking member slidingly installed in the housing for locking the latch; a sub-locking member slidingly installed in the housing and disposed in one side of the main locking member; a hook pivotally and movably installed in any one of the main locking member and the sub-locking member; a stopping threshold formed in the other one (wherein the hook is not installed) of the main locking member and the sub-locking member; and a locking plate slidingly installed in the housing for pivotally moving the hook, wherein the main locking member and the sub-locking member are sliding together when the hook is held by the stopping threshold by the sliding of the locking plate, and only the sub-locking member is sliding when the hook is separated from the stopping threshold by the sliding of the locking plate, so that even if the door lever is being pulled when the door is being locked, the unnecessary force is not transferred to the other components such as a latch, a main locking member, and the like.

A latch including a locking lever pivotally mounted to the latch. The latch also including an intermittent lever pivotally coupled to the locking lever at a first end, wherein movement of the locking lever causes a movement of the intermittent lever. A gear is pivotally coupled to a second end of the locking lever such that rotation of the gear causes movement of the locking lever. The locking lever is formed from a resilient material and has an area of reduced thickness reproducing a spring effect. Movement of the second end of the locking lever with respect to the first end of the locking lever creates a biasing force in the locking lever.

A double-locking door lock apparatus (100) for a vehicle includes a latch mechanism (10), an inside open lever (21), an outside open lever (22), an open link (23), a lock mechanism switching the open link (23) between unlocked and locked states, and a double lock mechanism switching a vehicle door between a double locked state and a double-lock cancelled state, the lock mechanism including an active lever (25) shifting the open link (23) between the unlocked and locked states, and the double lock mechanism including a double lock lever (27) shifted from an unset position to a set position by a setting operation of a double-locking member to restrain the open link (23) from shifting from the locked state to the unlocked state, the double lock lever (27) shifted from the set position to the unset position by an unsetting operation of the double-locking member to allow the open link (23), to shift from the locked state to the unlocked state.
