Abstract

An opening-and-closing device for vehicle door includes: a close-latch mechanism which holds a door at a closed position; an open-latch mechanism which holds the door at an opened position; an electric-powered releasing mechanism which operates the close-latch mechanism; an open-latch interlocking mechanism which operates from an initial position toward a canceling direction in conjunction with an operation of the open-latch mechanism from an unlatched position to a latched position; and a relay mechanism which changes a state of a transmission path of releasing operation from a connected state to a disconnected state to allow returning of a first ratchet which has stopped in a releasing position.

First claim

What is claimed is:

1 . An opening-and-closing device for vehicle door comprising:
a close-latch mechanism that is provided to a door, the close-latch mechanism including a first latch configured to move from an unlatched position to a latched position and a first ratchet configured to engage with the first latch in the latched position to hold the door in a closed position; an open-latch mechanism that is provided to the door, the open-latch mechanism including a second latch configured to move from an unlatched position to a latched position and a second ratchet configured to engage with the second latch in the latched position to hold the door in an opened position; an electric-powered releasing mechanism that is configured to operate the first ratchet to a releasing position; an open-latch interlocking mechanism that is configured to operate from an initial position toward a canceling direction in conjunction with a motion of the second latch from the unlatched position to the latched position; and a relay mechanism that is configured to change a state of a transmission path of releasing operation from a connected state to a disconnected state to allow returning of the first ratchet which has stopped in the releasing position, a releasing operation of the electric-powered releasing mechanism being transmitted to the first ratchet in the connected state and not being transmitted to the first ratchet in the disconnected state, the connected state changing to the disconnected state by the open-latch interlocking mechanism operating toward the canceling direction.

2 . The opening-and-closing device for vehicle door according to claim 1 , wherein
the open-latch interlocking mechanism includes a cam lever configured to pivot by making contact with the second latch pivoting from the unlatched position to the latched position, a cancel lever coupled to the relay mechanism via a cable and configured to pivot integrally with the cam lever, and an urging member configured to urge the cam lever and the cancel lever, which have pivoted by making contact with the second latch, to return to initial positions, and the relay mechanism can be changed from the connected state to the disconnected state with the cable pulled by pivoting of the cancel lever.

3 . The opening-and-closing device for vehicle door according to claim 2 , wherein
the relay mechanism includes a relay lever configured to pivot by the releasing operation of the electric-powered releasing mechanism, a transmission lever configured to pivot in conjunction with the relay lever to transmit the releasing operation to the first ratchet, a disconnecting lever configured to pivot, with the cable pulled by pivoting of the cancel lever, to cancel interlock between the relay lever and the transmission lever, and a floating pin movably inserted through a hole provided in the relay lever, a hole provided in the transmission lever, and a hole provided in the disconnecting lever, and the hole in the transmission lever has an inclined portion against which the floating pin slides thereby allowing the disconnecting lever to return to an initial position, when the relay lever returns to the initial position after the interlock between the relay lever and the transmission lever is canceled by pivoting of the disconnecting lever.
