Disclosed herein is an apparatus for moving a headrest. The apparatus includes a push member, a horizontal member which is horizontally moved by the push member, a return spring which returns the horizontal member to its original position, a power transmission unit which transmits the movement of the horizontal member, a first pinion gear which rotates using drive force transmitted from the power transmission unit, a second pinion gear which receives drive force from the power transmission unit and rotates in a direction opposite to the rotation of the first pinion gear, a spring which is connected to the first pinion gear and the second pinion gear, a movable member which is fitted into the spring, and a stay rod which has at least two locking notches spaced apart from each other so that the horizontal member is locked to a selected one of the locking notches. Therefore, the structure of the apparatus is compact. |
