Vehicle door operating mechanism

摘要

A vehicle door operating mechanism includes a ratchet interlocking lever, a handle interlocking lever, a motor power transmitting lever, and a force relaying member movable between a normal unlocking position, at which a force is transmittable from the handle interlocking lever and the motor power transmitting lever to the ratchet interlocking lever, and a locking position, at which the force is not transmittable from the handle interlocking lever and the motor power transmitting lever to the ratchet interlocking lever, wherein an emergency unlocking position, at which the force is transmittable from the handle interlocking lever to the ratchet interlocking lever and the force is not transmittable from the motor power transmitting lever to the ratchet interlocking lever, is set within a moving range of the force relaying member, and the motor power transmitting lever includes a guide portion for retaining the force relaying member at the emergency unlocking position.

主权项

1. A vehicle door operating mechanism comprising:
a ratchet interlocking lever interlinked with a ratchet of a latch/ratchet mechanism for retaining a vehicle door of a vehicle in a closed state and rotatable in a first rotational direction from an initial position when a retention of the vehicle door in the closed state by the latch/ratchet mechanism is released; a handle interlocking lever interlinked with the ratchet interlocking lever and configured to rotate in the first rotational direction from an initial position while receiving an operating force generated in response to an opening operation of an operating handle to thereby apply a force in the first rotational direction to the ratchet interlocking lever; a motor power transmitting lever interlinked with the ratchet interlocking lever and configured to rotate in the first rotational direction from an initial position while receiving a force generated by a release motor to thereby apply the force in the first rotational direction to the ratchet interlocking lever; and a force relaying member provided between a) the ratchet interlocking lever and the handle interlocking lever and b) the motor power transmitting lever and movable between a normal unlocking position, at which the force is transmittable from the handle interlocking lever and the motor power transmitting lever to the ratchet interlocking lever in response to a locking/unlocking operation of a lock operating portion that is used for locking and unlocking the vehicle door, and a locking position, at which the force is not transmittable from the handle interlocking lever and the motor power transmitting lever to the ratchet interlocking lever, wherein a moving range of the force relaying member includes an emergency unlocking position, at which the force is transmittable from the handle interlocking lever to the ratchet interlocking lever and the force is not transmittable from the motor power transmitting lever to the ratchet interlocking lever, the motor power transmitting lever includes a guide portion which is configured to retain the force relaying member at the emergency unlocking position when the motor power transmitting lever is within an entire rotation range of the motor power transmitting lever in the first rotational direction except for the initial position, and the lock operating portion is exposed to the vehicle interior on the surface of the vehicle door facing the vehicle interior.
