The present invention relates to a car headrest tilting device, the device comprising: a fixing bracket; a mounting bracket; a front link and a rear link disposed between and connected to the fixing bracket and the mounting bracket such that both ends of each of the front link and the rear link are rotatable; a latch gear formed on an upper end of one side of the fixing bracket; a pole rotatably installed on the mounting bracket and selectively engaged with one of gear grooves of the latch gear; a release plate rotatably installed on the fixing bracket and rotating the pole to a release position when the mounting bracket moves to the forefront; and a return spring installed between the fixing bracket and the rear link to always apply a force to rotate the mounting bracket rearward. Therefore, in the event of a collision, the present invention can prevent the pole from being unlocked and the headrest from unconditionally returning to its initial position, and thus can more effectively prevent occupant injuries.

    La présente invention concerne un dispositif d'inclinaison d'appuie-tête de voiture, le dispositif comprenant : un support de fixation ; un support de montage ; un élément de liaison avant et un élément de liaison arrière disposés entre le support de fixation et le support de montage et reliés à ceux-ci de telle sorte que les deux extrémités de chacun de l'élément de liaison avant et de l'élément de liaison arrière peuvent tourner ; un engrenage de verrouillage formé sur une extrémité supérieure d'un côté du support de fixation ; un montant installé de manière rotative sur le support de montage et mis en prise de manière sélective avec l'une des rainures d'engrenage de l'engrenage de verrouillage ; une plaque de dégagement installée de manière rotative sur le support de fixation et faisant tourner le montant vers une position de dégagement lorsque le support de montage se déplace vers l'avant ; et un ressort de rappel installé entre le support de fixation et l'élément de liaison arrière pour appliquer en continu une force pour faire tourner le support de montage vers l'arrière. Par conséquent, en cas de collision, la présente invention peut empêcher le déverrouillage du montant et le retour inconditionnel de l'appuie-tête à sa position initiale, et peut ainsi empêcher plus efficacement des blessures d'occupant.

    본 발명은 자동차의 헤드레스트 틸팅 장치에 관한 것으로, 고정브라켓; 마운트브라켓; 상기 고정브라켓과 상기 마운트브라켓의 사이에 양단이 회동 가능하게 연결된 프론트링크 및 리어링크; 상기 고정브라켓의 일측부 상단에 형성된 래치기어; 상기 마운트브라켓에 회동 가능하게 설치되고, 상기 래치기어의 기어홈들 중 어느 하나에 선택적으로 치합되는 폴; 상기 고정브라켓에 회동 가능하게 설치되고, 상기 마운트브라켓이 최전방으로 이동할 때 상기 폴을 릴리스 위치로 회동시키는 릴리스플레이트; 및 상기 고정브라켓과 상기 리어링크 사이에 설치되어 항상 상기 마운트브라켓을 후방으로 회동시키는 힘을 가하는 리턴스프링;을 포함한다. 따라서 충돌 사고시 폴의 잠금 상태가 해제되어 헤드레스트가 무조건 초기 위치로 복귀하는 것이 방지됨으로써 탑승자의 부상을 보다 효과적으로 방지할 수 있다.
