Abstract

로터리 액츄에이터로 동작시키는 프리텐셔너에 있어서, 로터와 시이트벨트 권취축의 클러치계합충격을 감소시킨다.In a pretensioner operated by a rotary actuator, the clutch engagement shock between the rotor and the seat belt winding shaft is reduced.

시이트벨트 권취축(1)을 회전시키는 회전액츄에이터(3)와, 그 압력실(C)에 작동가스를 공급하는 가스 제너레이터(4)와, 압력실(C)에 공급되는 가스압으로 로터 (31)를 권취축(1)에 연결시키는 클러치장치(5)를 구비한다. 클러치장치(5)는 공간(S)에 배설되고, 그것은 래칫휘일(51)과 이동축선(X)을 래칫휘일(51)의 중심축선(Y)과 소정간격(D)을 두고 교차하는 방향으로 지향하는 클러치키(52)로 구성된다.The rotary actuator 3 which rotates the seat belt winding shaft 1, the gas generator 4 which supplies a working gas to the pressure chamber C, and the rotor 31 by the gas pressure supplied to the pressure chamber C. The clutch device 5 which connects to the winding shaft 1 is provided. The clutch device 5 is disposed in the space S, which is a direction in which the ratchet wheel 51 and the moving axis X intersect with the central axis Y of the ratchet wheel 51 at a predetermined distance D. It consists of a directed clutch key 52.
