Abstract

The invention relates to the technical field of automobile safety belts, and particularly to a retractor core shaft assembly with a load limiting stopping function and a safety belt retractor. The retractor core shaft assembly with the load limiting stopping function includes a coiling cylinder, a load limiting rod, a block nut, a load limiting head and a shaft head, wherein the load limiting headis connected with the shaft head; the block nut is connected with the coiling cylinder; the load limiting head is in threaded connection with the block nut; the end, inside the coiling cylinder, of the load limiting rod is connected with the load limiting head, and the other end is connected with the coiling cylinder. When automobile collision occurs, and the load limiting function of the coilingcylinder starts, a safety mesh belt is pulled out continuously, at the time, the coiling cylinder rotates and the block but rotates and moves to the root direction of the external threaded connectionpart on the load limiting head, and rotation stops until the block nut reaches to the root part of the load limiting head to force the coiling cylinder to stop rotating, and the safety mesh belt cannot be pulled out continuously, so that the load limiting stopping function of the retractor core shaft assembly is realized.

Description

technical field [0001] The invention relates to the technical field of automobile seat belts, in particular to a retractor mandrel assembly and a seat belt retractor with a force-limited stop function. Background technique [0002] In the existing force-limiting seat belt, when a collision accident occurs, the pretensioner is activated to prevent the safety webbing from being pulled out of the retractor, thereby realizing the body restraint effect on the occupant; but in the impact force and the inertia of the human body Under the action, the force on the safety webbing increases, so that the torque of the force limiting rod inside the retractor increases accordingly. When the torque reaches the starting torque of the force limiting rod, the safety webbing can be pulled out continuously, thereby buffering the safety webbing The impact on the occupant's chest; however, after the force limiting lever is activated, the safety webbing can be pulled out all the way, so the occupa...
