Abstract:
The present invention relates to a device for sliding a headrest towards the front direction, more particularly, to a headrest sliding device wherein a ratchet and a release lever are installed in a side link which is a movable part, and the protrusion of the ratchet is being pushed up to release the locking so that the headrest is returned to its original position.

Claim (Index 1):
A headrest sliding device comprising:\n a lower side bracket wherein teeth are formed along the front to rear direction and being fixed to a stay; a front side link whose lower portion is rotatably connected to the front side of the lower side bracket through a first front side hinge shaft; a rear side link whose lower portion is rotatably connected to the rear side of the lower side bracket through a first rear side hinge shaft; a left side link and a right side link connected to the left and the right sides of the upper sides of the front side link and the rear side link through a second front side hinge shaft and a second rear side hinge shaft, respectively; a return spring for applying a restoring force to the front side link with respect to the lower side bracket; a ratchet disposed in either one of the left side link and the right side link so as to be engaged with the teeth, and being supported by a rotation axis along the left to right direction; a release protrusion formed in the ratchet; and a release lever which is supported at the side link wherein the ratchet is supported, and releases the gearing state by lifting up the release protrusion when an external force is applied thereto.
