Abstract

좌석벨트(13)용 프리텐셔너(10)가 연속사용을 위하여 프리텐셔너의 상태를 조절토록 작동후에 용이하게 교환되는 비교적 저렴한 가스발생 카트리지(12)를 이용한다. 카트리지는 산탄총의 탄약형태와 유사하고 놀이쇠뭉치(22)내에 장전된다. 카트리지는 가스발생 파이로테크닉물질에 의하여 발생된 가스가 피스턴(36)을 전선시키고 관련기구를 통하여 느슨한 좌석벨트(13)을 권취한다.

Description

좌석벨트 프리텐셔너
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 벨트견인기구의 피니언기어와 결합되는 래크를 갖는 놀이쇠뭉치내에 장전되는 교환 가능한 좌석벨트 프리텐셔너카트리지의 단면도.
제2도는 제1도의 2-2선 단면도.
제3도는 제1도의 화살표 “3” 방향에서 본 측면도.

Claims (3)

  1. 놀이쇠뭉치와 폐쇄단부 및 개방단부를 갖는 실린더 상기 실린더내의 피스턴, 상기 피스턴에 부착된 래크와 상기 실린더의 개방단부를 향하여 상기 피스턴과 래크를 구동시키도록 실린더의 폐쇄단부와 피스턴사이의 상기 실린더내에 장입된 파이로테크닉물질로 구성되는 상기 놀이쇠뭉치내의 교환가능한 카트리지로 구성되고 상기 래크와 분리가능하에 결합되는 피니언기어와 상기 피니언기어에 의하여 구동되는 좌석벨트의 견인기구로 구성되어 상기 파이로테크닉물질의 점화와 상기 피스턴의 전진시에 느슨한 좌석벨트를 권취도록 상기 피스턴을 상기 좌석벨트에 연결하는 수단이 구성되어 있음을 특징으로 하는 좌석벨트 프리텐셔너.
  2. 청구범위 1항에 있어서, 상기 피니언기어가 상기 피스턴과 래크의 전진에 대하여 회전속도를 변화시킬 수 있도록 가변직경을 가짐을 특징으로 하는 좌석벨트 프리텐셔너.
  3. 놀이쇠뭉치와 폐쇄단부 및 개방단부를 갖는 실린더 상기 실린더내의 피스턴과 실린더의 개방단부를 향하여 상기 피스턴을 구동시키도록 실린더의 개방단부와 상기 피스턴사이의 상기 실린더내에 장입된 파이로테크닉물질로 구성되는 상기 놀이 쇠뭉치내의 교환가능한 카트리지로 구성되고 상기 파이로 테크닉물질의 점화와 상기 피스턴의 전진시에 느슨한 좌석벨트를 권취도록 상기 좌석벨트에 상기 피스턴을 연결하는 수단이 구성되어 있으며, 이 수단을 상기 피스턴에 연결되고 좌석벨트에 접촉되게 배치된 풀리로 구성되어 상기 피스턴의 전진과 상기 풀리가 상기 벨트를 긴장시킴을 특징으로 하는 좌석벨트 프리텐셔너.
