Automobile safety belt retracting mechanism

Abstract

The invention discloses an automobile safety belt retracting mechanism comprising a retracting roller and a [-shaped frame. Ratchet wheel holes are formed in the outer walls of the two sides of the [-shaped frame. A pair of side frames are fixed to each of the portions, located above and below the corresponding ratchet wheel hole, on the outer wall of each of the two sides of the [-shaped frame. Amovement mechanism is fixed to the outer wall of each same side of the [-shaped frame through the corresponding two pairs of side frames. Each movement mechanism comprises two first slide rods arranged in parallel. In the automobile safety belt retracting mechanism, ratchet wheels are fixed to the portions, corresponding to the positions where the ratchet wheel holes are located, at the two endsof a retracting roller. By arranging the movement mechanisms capable of driving the retracting roller to move close to an opening of the [-shaped frame upwards, when an automobile suddenly slows downand turns at a high speed, the ratchet wheels and the ratchet wheel holes can be connected in a clamping manner to limit the retracting roller to release a safety belt; the tensioning effect achievedfor the safety belt through a retractor when the automobile turns at a high speed is ensured, and the travelling safety of drivers and passengers is protected; and the overall structure is simple, theproduction cost is low, and certain market application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto safety belt retracting mechanism. Background technique [0002] The car seat belt is a safety device for restraining the occupant during a collision and avoiding a secondary collision between the occupant and the steering wheel and instrument panel during a collision or avoiding rushing out of the vehicle during a collision and causing death or injury. The function of the retractor is to store the webbing and lock the webbing to be pulled out. It is the most complicated mechanical part in the safety belt. There is a ratchet mechanism inside the retractor. Under normal circumstances, the occupant can pull the webbing freely and at a constant speed on the seat, but once the continuous pulling process of the webbing from the retractor stops or when the vehicle encounters an emergency, the ratchet mechanism will work. The locking action automatically locks the webbing to ...

AI Technical Summary

Problems solved by technology

[0003] During the use of the existing automobile safety belt retracting mechanism, when the automobile suddenly decelerates, the internal limit block and the ratchet mechanism are clamped to restrict the retracting reel of the retracting mechanism to release the seat belt. The structure can only limit the release of the seat belt when the car suddenly decelerates, but it is less effective in restricting the release of the seat belt when the car is turning sharply
