Vehicle door latch device

A vehicle door latch device comprises a longitudinal open link having an upper end connected to an open lever and a lower end connected to a lock lever. The open link is displaced into a locked position when it moves toward an exterior side of a latch body and is not overlapped with a raised portion of the latch body. A self-canceling lever is attached to the latch body by a first shaft and has a first arm connected to an ratchet pin and a second arm extending toward the open link. The second arm restores the open link to an unlocked position by when a ratchet is rotated by a contact with a latch. The first shaft is located on an exterior side of the ratchet pin. The second arm is overlapped with the open link when the open link is in the locked position.

Vehicle door latch device with self-cancelling mechanism

A child proof apparatus for a vehicle door latch device comprises a child lever adapted to be manually turned, an intermediate lever having an abutting end engageable with an open lever and an elongated slot, and a child link having a child pin slidably engaged in the elongated slot. The pin is integrally formed in the child link and has a first engaging means which is engaged in the slot by being turned by a right angle after the pin is inserted into the slot. The child link has a snap fastener portion integrally formed therewith which is rotatably engaged in a second hole of the child lever. The child lever has a shaft integrally formed therewith having a second engaging means which is engaged in the slot by being turned by a right angle after the shaft is inserted into the slot.
