A headrest has a mount fixable on a vehicle seat, a head support, first and second links each having one end pivoted on the mount and an opposite end pivoted on the head support for movement of the head support relative to the mount forward toward a head of a user in the seat and rearward away from the head of the user. First latch formations on the links and second latch formations fittable with the first latch formations and either on the head support or on the mount are movable between a latching position engaged with each other to arrest pivoting of the links and forward and rearward movement of the headrest relative to the mount, and a release position disengaging the first and second latch formations from each other to permit such pivoting and movement.

The present invention relates to a headrest moving device, more particularly, relates to a headrest moving device comprising: a moving member rotatably connected to a second member; and a guide member connected to the first member and guided by the first member and having a locking groove formed therein for guiding the moving member so that the number of parts of the device is significantly reduced, the weight of the apparatus can be reduced, the manufacturing cost of the apparatus can be reduced, the structure of the apparatus can be simplified since the button can be omitted, and the convenience of usage is enhanced since if a user presses one time, the headrest is positioned in a first position and if presses one more time in the same way the headrest is positioned in a second position.

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.

A device for sliding a headrest towards the front direction includes a ratchet and a release lever installed in a side link which is a movable part. A release protrusion is formed in the ratchet and disposed almost in parallel with the hinge shaft of the ratchet. The release protrusion of the ratchet is pushed up to release the locking so that the headrest is returned to its original position.

A headrest assembly according to an exemplary aspect of the present disclosure includes a head restraint configured to rotate from a first locked position to a second locked position to incline the head restraint relative to a seat back. Further, the head restraint is configured such that rotation of the head restraint beyond the second locked position causes the head restraint to become urged back to the first locked position. The head restraint includes a ratchet assembly having a pawl and pawl spring, and the pawl spring includes a first section and a second section. The first section of the pawl spring is configured to contact the pawl when the head restraint is rotated from the first locked position to the second locked position, and the second section of the pawl spring is configured to contact the pawl when the head restraint is rotated beyond the second locked position.
