A door lock apparatus includes a latch mechanism having a latch being engagable with a striker and having a pawl stopping a rotation of the latch being engaged with the striker at a half latched position and a fully latched position, a half latch detection portion, a full latch detection portion, a driving portion for rotating the latch being in the half latched position toward the fully latched position, an intermediate position detection portion and a controlling portion for controlling the driving portion to start the driving portion in order to rotate the latch being in the half latched position toward the fully latched position, to stop the drive of the driving portion when the latch is in the fully latched position and to temporally stop the driving portion when the latch is in the intermediate position.

Door lock apparatus

A door latch apparatus for a vehicle includes a latch, a pawl, a motor, a release power transmitting mechanism, an active rotary member arranged in a standby area in a normal state, a driven rotation member rotating about a rotational shaft arranged in parallel with a rotational shaft of the active rotary member and away therefrom, a cam projection formed at the active rotary member, a cam groove formed at the driven rotation member and slidably engaging with the cam projection, the cam groove extending away from a reference line when the standby area is arranged close to one side of the rotation range and the active rotary member is positioned close to the one side of the rotation range, and a standby state detecting device detecting whether or not the active rotary member is arranged within the standby area based on a rotational position of the driven rotation member.

Door latch apparatus for vehicle

A device includes a latch of a door and rotates while engaging with a striker of a vehicle body; a pawl which is rotatable between a latched position to restrict a rotation of the latch and a unlatched position to permit the rotation of the latch; a motor; a release power transmitting unit which transmits a rotational power of the motor to the pawl and rotates the pawl from the latched position to the unlatched position. The device further includes a motor-side rotation board, a relay rotation board, and a pawl-side rotation board, which are connected to be integrally rotatable. The relay rotation board become movable to a power shutoff position by pressing operation though an operating hole formed in a door. In the power shutoff position, connecting between the three boards is released, and the motor-side rotation board and the pawl-side rotation board become individually rotatable.

Vehicle door latch device

A door locking system for a vehicle includes a striker, a latch, a pawl allowing and regulating the latch to rotate, a lock release operating portion moving the pawl to release the regulation on the latch rotation, a latch driving motor driven in one direction to shift the door to a fully closed state from a half-closed state, the latch driving motor driven in the other direction to move the pawl to be release position when the lock release operating portion is operated, and a power transmission system switching mechanism connecting a motor output shaft of the motor to the latch for driving the latch in the locking direction, the power transmission system switching mechanism connecting the motor output shaft of the motor to the pawl for moving the pawl to the release position and including a first canceling mechanism for switching a power state.
