Abstract

본 발명은 차량의 시트에 구비되는 시트벨트의 압력강하식 로드리미터에 관한 것으로, 일반적으로 차량의 탑승자를 좀더 안전하게 보호할 수 있도록 하고자 하는 경우에 상기 시트벨트(3)를 이루는 버클어세이(8)의 일측 소정부위에 충격감쇄기능을 갖는 로드리미터가 구비되어 있지 않음으로 인해 차량의 급정거 또는 정면 충돌시 탑승자의 안전이 제대로 보장될 수 없게 되는 문제점을 해소하기 위하여, 차량의 시트(1)에 구비되는 시트벨트(3)의 버클어세이(8)측 앵커부(7)의 일측에 소정의 압력강하식 로드리미터(9)가 구비되되, 상기 압력강하식 로드리미터(9)는 내측으로 상기 버클어세이(8)에 고정되는 연결바(10)의 일단에 동일체로 피스톤(11)이 소정의 가압력을 발생시킬 수 있도록 상기 피스톤(11)의 전진력을 1차로 완화시키는 소정의 가스가 봉입된 제1실린더(12)와, 상기 제1실린더(12)의 외측에 상기 피스톤의 전진력을 2차로 완화시키도록 소정의 유격을 갖고 구비되는 제2실린더(13)로 이루어짐으로써 상기 압력강하식 로드리미터(9)에 의해 차량에 탑승한 탑승자의 신체에 과도하게 걸리는 하중과 급감속에 의한 충격을 순차적으로 감쇄시킬 수 있게 되는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pressure-drop type load limiter for a seat belt installed on a seat of a vehicle. In general, when a passenger of a vehicle is to be protected more safely, In order to solve the problem that the safety of the occupant can not be guaranteed when the vehicle suddenly stops or collides in front of the vehicle due to the absence of the road limiter having the impact damping function at one predetermined portion of the vehicle 1, The load limiting device 9 is provided on one side of the buckle attachment 8 side anchor portion 7 of the seat belt 3 provided with the pressure drop type load limiter 9, A predetermined gas which firstly relaxes the advancing force of the piston 11 is sealed in one end of the connecting bar 10 fixed to the buckle retainer 8 so that the piston 11 can generate a predetermined pressing force The And a second cylinder (13) provided outside the first cylinder (12) with a predetermined clearance so as to secondarily relax the forwarding force of the piston, so that the pressure drop type load It is possible to sequentially attenuate the load caused by excessive load on the body of the occupant who rides on the vehicle by the limiter 9 and the impact caused by the rapid deceleration.
