A closure release device includes a housing fixedly attached to a closure and an actuating lever rotatably disposed on an axis of rotation on the housing. A crank lever is rotatably disposed on the axis of rotation. A coupling member is to selectively couple the actuating lever to the crank lever for rotation together. A shape memory alloy (SMA) actuator is to selectively cause the coupling member to selectively couple the actuating lever to the crank lever. The SMA actuator is electrically actuated. The crank lever is to connect to a latch to selectively release or engage the latch in response to a coupling state of the actuating lever with the crank lever and an actuation state of the actuating lever.

The subject matter of the present invention is a motor vehicle door lock, the basic construction of which is equipped with a locking mechanism (1, 2) consisting essentially of a rotary latch (1) and a detent pawl (2), furthermore with a release element (3) for the locking mechanism (1, 2) and with a storage element (4). The storage element (4) ensures an unobstructed opening movement of the rotary latch (1) from a closed position into an open position. According to the invention, for this purpose, the storage element (4) holds the release element (3) during the opening movement of the rotary latch (1) in an ineffective position with respect to the locking mechanism (1, 2).

A closure latch for a vehicle door is provided. 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 blowout latch includes a rotatable bolt that secures a first panel that is adjacent to a second panel to which the latch is affixed. The bolt is restrained by a toggle linkage that operates at one end of the bolt against a pressure-actuated spring. The linkage will release the bolt when an excessive opening force against the bolt exceeds a selected restraining force of the spring. When that condition occurs, the linkage will have deflected the spring and moved to a position where the end of the linkage bearing against spring loses it mechanical leverage with respect to the bolt. Thereafter, the bolt is free to continue rotation to a fully open position. The latch also includes a manual trigger release that disables the restraining linkage and permits free rotation of the bolt to the fully open position when this trigger is actuated.

A latch is provided. The latch having: a claw pivotally mounted to the latch for movement between an unlatched position and a latched position; a pawl pivotally mounted to the latch for movement between an engaged position and a disengaged position, wherein the pawl prevents movement of the claw into the unlatched position from the latched position when the pawl is in the engaged position and wherein the claw is able to move into the unlatched position from the latched position when the pawl is in the disengaged position; a release lever pivotally mounted to the latch for movement between a first position and a second position and operatively coupled to the pawl, wherein movement of the release lever from the first position to the second position moves the pawl from the engaged position to the disengaged position; and a housing having a back plate, each of the claw, the pawl, and the release lever being rotatably mounted to the back plate, the back plate including a back plate leg configured to transform from a un-deformed position to a deformed position in response to an impact applied to the latch, wherein the back plate leg interferes with movement of the release lever from the first position to the second position when it is in the deformed position.

The present invention relates to a vehicle door lock and an associated method for the operation thereof, wherein the vehicle door lock is equipped with a locking mechanism, which essentially consists of a catch and a pawl. The pawl has a contact surface for the catch, which rests on said contact surface when the locking mechanism is closed. According to the invention, a supporting element, which delays the opening of the locking mechanism, is associated with the pawl, so that the catch glides along the contact surface up to a predetermined opening angle until is it is released from the pawl.

A door opening prevention device in a broadside collision of a vehicle, having a latch assembly which locks and unlocks a door side striker in conjunction with an operation of an outside handle when the outside handle may be operated, may include a balance weight which may be rotatably coupled to a side surface of a claw disposed in the latch assembly, wherein the balance weight may be pivotable downward by inertia in the broadside collision of the vehicle, and a striker locking lever slidably engaged to the side surface of the claw and elastically biased upwards, wherein the striker locking lever may be fitted between the side surface of the claw and the door side striker to jam the claw and the door side striker while being moved in a down direction by contact with the balance weight by the inertia in the broadside collision of the vehicle.

A dual unlocking hood latch system allows a user to open a hood of the automobile vehicle while staying in the vehicle. The dual unlocking hood latch system includes a base fixed to a main body. The base includes a moving groove portion to guide the movement of a striker. A latch gear, which includes a plurality of locking portions, is pivotably attached to a front side of the base to retain the striker when the striker is entered through the moving groove portion to a locking position. A pawl, pivotably attached to the base, controls the movement of the latch gear by transmitting rotational motion when in contact. And a stopper portion, pivotably attached to the base, is elastically biased to move toward the pawl such that the stopper portion is pushed by the pawl to restrain pivoting movement of the latch gear.

A door lock device includes a latch mechanism which is releasably engaged with a striker and which has an operation receiving part for releasing engagement of the striker, a link movable between an unlock position where the engagement of the striker can be released and a lock position where the engagement cannot be released, and a lock plate for positioning the link into the unlock position or the lock position. A push lever 60, upon operation of the door handle, releases engagement of the striker by the latch mechanism 11 via the link 30 positioned in the unlock position and the operation receiving part 28. A bearing part 64 of the push lever 60 is rotatably supported by a bearing part 70 integrally formed in a main case 15.

The object of the invention is a motor vehicle latch demonstrating a locking mechanism comprising a catch and at least a pawl, a latch plate (1), whereby the locking mechanism can be accommodated in the latch plate (1) and the latch plate (1) demonstrates an inlet area (12), whereby a latch holder (13) can be inserted to interact with the locking mechanism in the inlet area (12) and with at least a deformation (11) formed in a peripheral area of the inlet area (12) in the latch plate (1), whereby the deformation (11) is arranged at least in places directly on an edge of the inlet area (12).
