According to the present invention, a power headrest apparatus automatically controls vertical direction movement and forward and backward direction movement of a headrest by using a motor, and sufficiently secures a forward and backward direction movement amount of the headrest while maintaining a forward and backward direction width of the headrest to be less than a predetermined level, by using a pair of link members which are arranged to be crossed in an X shape. The power headrest apparatus comprises: a support rod vertically supported in a seatback frame of a vehicle seat; a headrest unit having a fixing unit and an operating unit; a link unit having a first link member and a second link member; a first driving unit moving the support rod in a vertical direction; and a second driving unit relatively moving the operating unit with respect to the fixing unit.
본 발명에 따른 파워 헤드레스트 장치는, 모터를 이용하여 헤드레스트의 상하방향 이동 및 전후방향 이동을 자동으로 조절하되, X자 형태로 교차되어 배치되는 한 쌍의 링크 부재를 이용하여, 헤드레스트의 전후방향 폭을 일정 수준 이하로 유지하면서도 헤드레스트의 전후방향 이동량을 충분히 확보할 수 있게 된다.
