Abstract

로터리액츄에이터로 작동시키는 프리텐셔너에 있어서, 로터와 시이트벨트 귄추축과의 클러치의 계합작동을 원활하게 한다.In a pretensioner operated by a rotary actuator, the engagement operation of the clutch between the rotor and the seatbelt guiding shaft is smoothed.

시이트벨트권취축(1)을 회전시키는 로터리액츄에이터(3)와, 그 압력실(C)에 작동가스를 공급하는 가스제너레이터(4)와, 압력실(C)에 공급되는 가스압력으로 로터(31)를 권취축(1)에 연결시키는 클러치장치(5)등을 구비 한다.The rotary actuator 3 for rotating the seat belt winding shaft 1, the gas generator 4 for supplying the working gas to the pressure chamber C, and the gas pressure supplied to the pressure chamber C with the rotor 31 ) Is provided with a clutch device (5) for connecting the winding shaft (1).

클러치장치(5)는 공간(5)에 배설되고, 그것은 래칫회일(51)과, 그것에 향해서 로터(31)에 가동지지된 클러치 키이(52)와 클러치키이(52)로의 작동가스압력의 전달과 압력실(C)로의 작동가스의 공급을 차례로 제어하는 키이코넥터(53)로 구성한다.The clutch device 5 is arranged in the space 5, which transmits the working gas pressure to the ratchet wheel 51 and the clutch key 52 and the clutch key 52 supported by the rotor 31 toward it. It consists of the key connector 53 which controls supply of the working gas to the pressure chamber C in order.
