The invention discloses a safety belt force limiter which comprises a movable shaft, a fixed shaft and a force limiting rod, one end of the force limiting rod is fixedly connected with the movable shaft, the other end of the force limiting rod is fixedly connected with the fixed shaft, the safety belt force limiter further comprises a force limiting stopping assembly, and the force limiting stopping assembly is installed between the movable shaft and the fixed shaft; before collision, the movable shaft, the force limiting rod, the force limiting stopping assembly and the fixed shaft rotate synchronously; when collision occurs, the fixed shaft is locked, the movable shaft and the force limiting rod rotate, the movable shaft drives the force limiting stop assembly to move, and when the force limiting stop assembly moves to the limiting position, the force limiting stop assembly stops moving and limits rotation of the movable shaft. In one embodiment of the invention, a force-limiting stopping function is realized through the force-limiting stopping assembly, and the limiting position of force-limiting stopping is adjusted through the self-adaptive adjusting assembly according to the body types of different passengers. The function gives consideration to adjustment requirements and performance requirements at the same time, the number of experiments is reduced, the passenger restraint effect is improved, and the development cost is saved.

    本发明公开了一种安全带限力器,包括动轴、定轴和限力杆,所述限力杆的一端与所述动轴固定连接,另一端与所述定轴固定连接,还包括限力停止组件,所述限力停止组件安装在所述动轴与所述定轴之间;碰撞前,所述动轴、所述限力杆、所述限力停止组件和所述定轴同步转动;碰撞时,所述定轴被锁定不动,所述动轴和所述限力杆转动,所述动轴带动所述限力停止组件运动,当所述限力停止组件运动到极限位置时停止运动,并限制所述动轴转动。本发明的一实施例中,通过限力停止组件实现限力停止功能,通过自适应调节组件根据不同乘员体型调整限力停止的极限位置。该功能同时兼顾了法规要求和性能要求,有利于减少实验次数,提高乘员约束效果,节约开发成本。
