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.

Door latch device in a motor vehicle

A door latch device in a motor vehicle comprises an engagement portion which can engage with a striker of a vehicle body; an operating lever operated with a handle on a door of the vehicle to open the door; a locking lever which moves between an unlocking position where the engagement portion can be disengaged from the striker and a locked position where the engagement portion cannot be disengaged from the striker; a first subsidiary lever moving with the locking lever; a second subsidiary lever connected to the operating lever and moving with the first subsidiary lever; a spring exerting a force to the first subsidiary lever and the second subsidiary lever; and a blocking member moving between a blocking position and an unblocking position. When the blocking member is in the blocking position, a locking knob is actuated for unlocking to allow the locking lever and the first subsidiary lever to move from the locked position to the unlocking position against a force of the spring.

An actuator for a vehicle, in particular for an automobile door lock includes a rotatable rotor; a lever that is disposed so as to be swingable between a first position and a second position; and an engagement mechanism through which the lever is engaged with the rotor. The engagement mechanism also includes a protrusion that engages with the rotor; and a guide mechanism that makes, along with rotation of the rotor, the lever swing between the first position and the second position, and allows, when the rotor stops rotating, a movement of the lever without turning the rotor.
