According to the present invention, in a sliding headrest (1), a lower ratchet (10) having a multi-stage ratchet tooth shape (10-1), an upper ratchet (50) having a tooth shape engagement ratchet pole (51), and a leaf spring (80) having a soft lock leaf pole (81) formed before locking a front line of the ratchet pole (51) of the ratchet tooth shape (10-1) are operated with a rotating body and a fixing body to realize a rotating body type sliding mechanism for a whiplash test to be satisfied. More specifically, regardless of application of a mass damper (1-5) enabling inertia relative motion different to be greater, the sliding headrest is applied to a small vehicle type of low engine idle rpm.

    본 발명의 슬라이딩 헤드레스트(1)는 다단계의 라쳇 치형(10-1)을 갖는 로어 라쳇(10)과 치형 맞물림의 라쳇 폴(51)을 갖는 어퍼 라쳇(50) 및 라쳇 치형(10-1)에 대한 라쳇 폴(51)의 최전방 락킹 전 형성되는 소프트 락킹(Soft Lock)의 리프 폴(81)을 갖는 리프 스프링(80)이 회전체와 고정체로 동작하여 회전체 방식 슬라이딩 메커니즘을 구현함으로써 Whiplash Test 충족이 이루어지고, 특히 관성상대운동 차이를 더욱 커지게 하는 매스 댐퍼(1-5)의 적용과 무관하게 낮은 엔진 공회전(IDLE RPM)의 소형 자동차종에 적용되는 특징을 갖는다.
