An actuator has an actuator housing fixed to an open side of a concave accommodating portion of a latch housing in a latch body, and also has a drive source, which is accommodated in the actuator housing, and an open lever for releasing a meshing part from a striker by being release-operated by the drive source. The open lever is accommodated in the actuator housing. A block member blocks a gap between the accommodating portion of the latch housing and the actuator housing.

When a trunk lid is opened, even in the case that the trunk lid is attached to a weather strip due to a frost of a vehicle body and the trunk lid is not sufficiently opened, a lock canceling member is restricted at an restriction canceling position during a period that a striker is returned to a waiting position from a bring-in position. Furthermore, a latch is not again engaged with the striker , and a drive mechanism does not bring in the trunk lid again.

Drive apparatus of trunk lid lock for motor vehicle

A door lock apparatus has a handle switch ( ), which is placed in the on condition when an actuator member for opening and closing a back door is operated, an open switch ( ), which is placed in the on condition when the door is closed to within a prescribed closure range, a drive circuit, which is formed so as to drive a door lock disengaging motor ( ) when both the handle switch ( ) and the open switch ( ) are in the on condition, and a self-holding circuit holding a condition in which the drive circuit is formed and, in response to the open switch going into to off condition, releasing the condition in which the drive circuit is formed.

Door lock apparatus

The lock device has a latch which is interposed between a base member and a reinforcing plate and is for rotating between an engagement position and an engagement released position. The engagement position is where the latch is to be engaged with a striker when closing an openable body. In addition, the lock device has a locking lever for constraining the latch at the engagement position. The latch by a latch shaft and the locking lever by a lever shaft each are mounted to a back side of the base member with the reinforcing plate. While the reinforcing plate is provided with a projection for fixing engagement which projects toward inside as seen from outside. The projection for fixing engagement fixes a detecting switch to be supported for detecting movement of the latch by fitting in a fitting portion provided to a switch body of the detecting switch.

An electric lid closure generally comprises a lock unit mounted to a trunk lid and an electric closing unit mounted to a trunk room mouth. The lock unit includes a latch plate, and the electric closing unit includes a support base, a striker base pivotally connected through a pivot pin to the support base, a striker formed on the striker base and engageable with the latch plate, and an electric power mechanism for pivoting the striker base between uppermost and lowermost positions by an electric power. A leading edge of the striker is inclined relative to an imaginary plane over which the striker base turns about the pivot pin.

Electric lid closure

An electric lid closure generally comprises a lock unit mounted to a trunk lid and an electric closing unit mounted to a mouth portion of a trunk room. The lock unit includes a latch plate and a locking plate by which the latch plate is locked at its latch position. The electric closing unit includes a movable striker engageable with the latch plate, and an electric power mechanism for moving the movable striker between an uppermost position and a lowermost position with an electric power. A first position sensor senses whether the movable striker assumes the uppermost position or the lowermost position. A second position sensor senses whether the trunk lid passes by a critical position or not. The critical position corresponds to a position of the movable striker which is above the uppermost position. A third position sensor senses whether the locking plate locks the latch plate or not. A control unit energizes the electric closing unit to pull down the trunk lid to a full close position only when the first position sensor senses the movable striker assuming the uppermost position, the second position sensor senses the trunk lid passing by the critical position and the third position sensor senses the latch plate being locked by the locking plate.

An automotive lid lock device comprises a lock proper which includes a latch plate and a locking plate. The locking plate is pivotal between a locking position to lock the latch plate and an unlocking position to release the latch plate. The lid lock device further comprises a power unlocking mechanism for pivoting the locking plate to the unlocking position with an aid of an electric power. The power unlocking mechanism includes an electric motor; a worm connected to an output shaft of the motor to rotate therewith; a worm wheel operatively engaged with the worm and a release lever extending between the locking plate and the worm wheel to pivot the locking plate from the locking position to the unlocking position when the worm wheel is turned in a given direction. The release lever, the locking plate and the worm wheel are so arranged that when the worm wheel is turned in the given direction, the worm wheel pushes the release lever toward the locking plate.

Automotive lid lock device with power unlocking mechanism

A door hinge assembly is disclosed, which comprises a door hinge assembly for pivotally connecting a door to a fixed structure. The assembly comprises a first wing member secured to the fixed structure, the first wing member having first aligned bores formed therethrough; a second wing member secured to the door, the second wing member having second aligned bores formed therethrough, the first and second wing members being so arranged that all of the first and second aligned bores are aligned; a pivot shaft passing through the aligned first and second bores to pivotally connect the first and second wing members; plastically deformable bushes respectively disposed in the second bores while rotatably receiving therein the pivot shaft; a first structure for suppressing rotation of the pivot shaft relative to the first bores; and a second structure for suppressing rotation of the bushes relative to the second bores. Each bush includes a tubular part intimately and tightly received in the corresponding one of the second bores, and a first flange part integrally formed on one end of the tubular part and intimately contacting with one surface of the second wing member. The bush further includes a slit which extends axially throughout the tubular and flange parts thereby providing the bush with circumferentially opposed terminal end portions.
