Abstract:
The present invention relates to a headrest folding device, more particularly, to a headrest folding device wherein a ratchet is connected between a release lever and a lock link which maintains the unfolding (upright) of a headrest, so that the operation of the release lever is not directly transferred to the lock link, but rather indirectly transferred to the lock link through the ratchet, thereby smoothing the operation of the release lever.

Claim (Index 1):
A headrest folding device comprising:\n a main bracket mounted in a seat back or a headrest; a stay, mounted in any one of said seat back and said headrest, being rotated with respect to said main bracket so as to be moved between the upright (unfolding) position and the folding position; a lock link whose one end is supported by said main bracket through a first hinge shaft and the other end is fixed to a horizontal bar of said stay; a first twisted coil spring whose one end is supported by said main bracket and the other end is supported by said horizontal bar of said stay; a release lever whose one end is supported by said main bracket through a second hinge shaft; a ratchet which is rotatably supported by said main bracket through a line shaft, and the contact thereof with said lock link is released by said release lever; a second twisted coil spring whose one end is supported by said main bracket and the other end is supported by said release lever; and an operating member whose operating force is applied to the other end of said release lever.
