Abstract

The invention provides a belt induction sensitive device of a safety belt retractor. The belt induction sensitive device comprises a ratchet wheel, a linkage lever, belt induction inertia steel balls and a return spring; the ratchet wheel comprises an end plate, ratchets formed at the edge of the end plate, an inertia steel ball groove for containing the belt induction inertia steel balls, a clamping jaw sliding groove, a return spring ratchet wheel end and a belt winding barrel shaft hole formed in the middle of the end plate; the linkage lever is connected with the end plate in a rotatable mode and comprises a force transmission rod, a return spring lever end arranged at one end of the force transmission rod, an impact rod arranged at the other end of the force transmission rod and arranged in the mode of facing the belt induction inertia steel balls and clamping teeth arranged at the tail end of the impact rod, one end of the return spring is connected to the return spring ratchet wheel end, and the other end of the return spring is connected to the return spring lever end. The belt induction sensitive device is fewer in part, simpler in structure, not high in requirement for installation environments, low in machining cost and easy to assemble.

Description

technical field [0001] The invention belongs to the technical field of safety belts of automobiles, and in particular relates to a belt-sensitive sensitive device of a safety belt retractor and a safety belt retractor. Background technique [0002] The safety belt device of the vehicle is a very important protection device in the vehicle. In the case of collision or sudden braking of the vehicle, the safety belt device can restrain the occupant and prevent the occupant from bouncing off the seat. And the seat belt retractor is the most important component in the seat belt device. [0003] The seat belt retractor retracts and unwinds the webbing through the rotation of the reel, so as to realize the triggering and disconnection of the restraint of the seat belt. At the moment of collision or emergency braking, in order to enable the restraint function of the seat belt well, the acceleration of the webbing pull out requires a good belt-sensing sensitive device to perform indu...
