According to the prevent invention, a safety belt (200) comprises a load limiter (1) connecting webbing (210) applied with a downward pulling force and left and right shoulder strings (220-1, 220-2) applied with an upward pulling force. Moreover, the load limiter (1) absorbs energy by deformation to limit the downward pulling force and the upward pulling force in a multi-stage manner. Therefore, a peak load caused by a collision is reduced, and damage to the load limiter (1) in a load larger than a new car assessment program (NCAP) collision load can be prevented.
본 발명의 안전벨트(200)는 하방향 당김 힘이 가해지는 웨빙(210)과 상방향 당김 힘이 가해지는 좌/우측 어깨끈(220-1,220-2)을 연결한 로드리미터(1)로 구성되고, 상기 로드리미터(1)가 변형을 통한 에너지 흡수로 하방향 당김 힘과 상방향 당김 힘에 대해 다단계 하중제한을 구현함으로써 충돌에 따른 절정하중(Peak Load)이 감소되면서도 NCAP(New Car Assessment Program) 충돌하중보다 큰 하중에서도 로드리미터(1)의 파손이 방지되는 특징을 갖는다.
