Abstract:
1. A door latch apparatus for a vehicle, comprising: a locking device; a release lever rotatably coupled on a base plate by a hinge pin and selectively locking the locking device, the release lever being provided with a locking part extending downwards; an open lever provided on the hinge pin so as to be rotatable along with the release lever; a rotating lever rotatably coupled on the base plate by a rotating shaft below the release lever, the rotating lever being connected to a door handle by a wire so that the rotating lever is rotated by operation of the wire; and an operating lever rotatably mounted on the hinge pin, the operating lever being provided with a locking protrusion; wherein the locking protrusion is disposed between the locking part of the release lever and the rotating lever when an external impact is not applied or applied less than a predetermined amount to the operating lever so that when the rotating lever rotates and pushes the locking protrusion, the locking protrusion pushes and rotates the locking part of the release lever to release the locking device, thus unlocking the door; and wherein when the external impact is applied to the operating lever beyond the predetermined amount in a side collision of the vehicle, the operating lever is reversely rotated by inertia and the locking protrusion is removed from between the locking part and the rotating lever.
