Abstract

A sliding door latch for a vehicle may include a striker mounted on inner surfaces of a front sliding door and a rear sliding door opening a vehicle body opening formed in a vehicle body by moving forward and backward in a longitudinal direction of the vehicle, which faces a vehicle compartment, a latch device suspending the striker to fix or release the striker, and a release operating device configured to release the latch device by operating door handles installed in the front sliding door and the rear sliding door, respectively.

First claim

What is claimed is:

1 . A sliding door latch for a vehicle, comprising:
a striker mounted on inner surfaces of a front sliding door and a rear sliding door opening a vehicle body opening formed in a vehicle body by moving forward and backward in a longitudinal direction of the vehicle, which faces a vehicle compartment; a latch device suspending the striker to fix or release the striker; and a release operating device configured to release the latch device by operating door handles installed in the front sliding door and the rear sliding door, respectively.

2 . The sliding door latch of claim 1 , wherein the latch device includes:
a striker suspension cam including a striker suspension groove suspending and fixing the striker; and a return spring configured to return the striker suspension cam to an original position after the striker suspension cam rotates.

3 . The sliding door latch of claim 2 , wherein the release operating device includes:
an operating cam configured to fix or release the striker suspension cam; an actuation wire connected to the door handle to be pulled or relaxed by operating the door handle; an actuation pin connected to the actuation wire and configured to be moved by the actuation wire when the actuation wire is pulled; a latch release pin configured to move with movement of the actuation pin to rotate the operating cam; and an operating wire connecting the latch release pin and the actuation pin.

4 . The sliding door latch of claim 3 , wherein the latch device is installed to be supported on the vehicle body through a vehicle body mounting bracket.

5 . The sliding door latch of claim 4 , wherein the vehicle body mounting bracket includes each of a front side and a rear side in the longitudinal direction of the vehicle to have a C-shaped cross-section and is formed such that a receiving groove in which a part of the striker when the front sliding door and the rear sliding door are closed is inserted and received is dug inside from an outside in a width direction of the vehicle on the front side and the rear side.

6 . The sliding door latch of claim 5 , wherein:
a front flange and a rear flange that extend in the longitudinal direction of the vehicle are integrally formed on the front side and the rear side, respectively, and the striker suspension cam is rotatably disposed on the front side and the rear side through a pin.

7 . The sliding door latch of claim 6 , wherein an operating groove is formed at the striker suspension cam and a part of the operating cam is inserted into and suspended on the operating groove.

8 . The sliding door latch of claim 6 , wherein the operating cam is rotatably disposed on the front side and the rear side through the pin.

9 . The sliding door latch of claim 6 , wherein guide grooves are provided at the front flange and the rear flange to extend in the longitudinal direction of the vehicle, respectively and the latch release pins are received in the guide grooves to move forward and backward in the longitudinal direction of the vehicle along the guide grooves.

10 . The sliding door latch of claim 6 , wherein the operating wire is inserted through one or more bushes, and as a result, the operating wire is disposed to be supported on the front flange and the rear flange.

11 . The sliding door latch of claim 3 , wherein:
door mounting brackets are fixedly mounted on the inner surfaces of the front sliding door and the rear sliding door, which face the vehicle compartment, and the striker is disposed to protrude through the door mounting bracket.

12 . The sliding door latch of claim 11 , wherein:
a receiving groove dug outward toward an outside of the vehicle compartment from the inner surface facing the vehicle compartment is formed at the door mounting bracket, and the actuation pin is disposed in the receiving groove to move along the receiving groove.

13 . The sliding door latch of claim 12 , wherein a return spring is disposed in the receiving groove in order to return the actuation pin to an original position after the actuation pin is pulled forward or backward in the longitudinal direction of the vehicle.

14 . The sliding door latch of claim 12 , wherein:
a wire holder is disposed at an end of the actuation wire, and the actuation wire and the actuation pin are connected to each other such that the wire holder is inserted into and coupled to a coupling groove provided at the actuation pin.
