PURPOSE: A headrest folding structure of a vehicle seat is provided to reduce the manufacturing cost and improve productivity by making a stopper for locking and releasing a headrest simple. CONSTITUTION: A headrest folding structure of a vehicle seat includes a housing, a rotation support member, a stay rod, a first spring, a locking unit, a stopper, a second spring, and an actuating unit. The housing is installed on a seat back of the vehicle seat. The rotation support member(111) is combined to be rotatable in the housing. The stay rod(110) is combined with the rotation support member to rotate together, and coupled with a headrest on the upper side. The first spring elastically supports the rotation support member or the stay rod in the direction folding the headrest. The locking unit(120) is provided on the lower side of the stay rod and has a protrusion(121) or groove. The stopper(130) is combined to rotate in the housing. The second spring elastically supports the stopper toward the locking unit. The actuating unit turns the stopper to be released from the locking unit. |
