The present invention relates to a digressive load limiter. The digressive load limiter according to the present invention, as the load limiter regulating a phenomenon in which a load acting on a webbing of a retractor fixing a pilot wheel connected to one end part of a spool on which the webbing is wound by operating a pretensioner when an impact is generated from the exterior exceeds a predetermined load, comprises: a torsion bar installed in a hollow unit formed at a center part of the spool, and twisting when the load acting on the webbing reaches a first load and limiting the load acting on the webbing; and an initial load increasing unit increasing the first load by suppressing relative rotation of the spool and the pilot wheel until the load acting on the webbing becomes a second load lower than the first load.

    본 발명에 따른 디그레시브 로드리미터는, 외부로부터 충격이 발생될 경우 프리텐셔너가 동작하여 웨빙이 감겨있는 스풀의 일단부에 연결된 파일럿 휠을 고정하는 리트렉터의웨빙에 작용하는 하중이 기설정된 하중을 초과하는 것을 조절하는 로드리미터로서, 스풀의 중앙부에 형성된 중공부에 장착되어, 웨빙에 작용하는 하중이 제1 하중에 도달하면 비틀려지면서 웨빙에 작용하는 하중을 제한하는 토션바, 및 웨빙에 작용하는 하중이 제1 하중보다 낮은 제2 하중이 될 때까지 스풀과 파일럿 휠의 상대 회전을 억제함으로써, 제1 하중을 상승시키는 초기하중증가부를 포함한다.
