Abstract

프리텐셔너를 벨트권취요소에 계탈하는 클러치기구의 동작을 확실화시킨다.
프리텐셔너(P)의 클러치기구(C)는 피스톤로터(A1)측의 구동회전부재(1)와 벨트권취축(S)축의 피동회전부재(2)의 사이에 계합부재(3)를 설치하여 구동된다.
구동회전부재(1)와 피동회전부재(1) 사이에 회전저항이 부여된 종동회전부재(4)를 배설한다.
종동회전부재(4)에는 구동회전부재(1)와 협동하여서 계합부재(3)를 지지하는오목부(40)를 형성하고, 그 배향면(41)을 계합부재(3)를 피동회전부재(2) 방향으로 안내하는 캠면으로 한다.
피동회전부재(1)와 종동회전부재(1)의 회전위상의 차이에 의해 계합부재(3)는 구동회전부재(1)와 피동회전부재(2)의 사이에 계합하여서 클러치 계합상태가 된다.

Claims (1)

  1. 파워소오스에 연결된 구동회전부재(1)와, 벨트권취요소에 연결된 피동회전부재(2)에 설치된 계합부재(3)를 보유하고, 상기한 구동회전부재(1)와 상기한 회동회전부재(2)의 사이의 회전위상의 차이에 의해 상기한 제한부재(3)를 구동회전부재(1)와 피동회전부재(2)의 사이에 계합시켜서 회전동력을 구동회전부재(1)로부터 피동회전부재(2)의 전달하는 클러치기구(7)를 구비하며, 상기한 파워소오스의 동력을 클러치기구(7)를 통하여 벨트권취요소에 전달하여 시이트벨트장치의 벨트를 감아죄는 프리텐셔너(P)에 있어서, 상기한 구동회전부재(1)와 피동회전부재(7)의 사이에 회전저항이 부여된 종동회전부재(4)가 배설되고 상기한 구동회전부재(1)와 종동회전부재(4)에는 계합부재(3)는 구동회전부재(1)와 중동회전부재(4)사이의 회전위상의 차이에 의한 수용공간의 축소에 의하여 피동회전부재(2) 방향으로 암출가능하게 상기한 오목부(40)에 게지된 것을 특징으로 하는 프리텐셔너.
