In the event of a collision, the seat belt can restrain the occupant in the seat to protect the occupant. On this basis, the load limiting function of seat belt can reduce the peak of the impact load on the occupant's chest and reduce the chest injury. In this paper, the load limiting system of the seatbelt is taken as the research object. By establishing the equivalent mechanical model, the design method of the diameter parameter of the torsion bar is obtained. At the same time, the fault tree research tool is used to obtain the important parameters that affect the load limiting stability of the retractor, and then the improvement and optimization scheme is provided. Finally, through sled test and vehicle test, the correctness of the design of load limiting value and load limiting stability are verified. Then we know how it affects the protection effect on rear row dummy, which provides a reference for the design of load limiting characteristics of the retractor.
