Abstract

The invention relates to a pre-tightening retractor preventing the open fire. The retractor comprises a pre-tightening wheel and a bent pipe, a pushing mechanism, a pre-tightening marble assembly, a limiting marble assembly and a limiting mechanism are arranged in the bent pipe, and the pushing mechanism pushes the pre-tightening marble assembly, the limiting marble assembly and the limiting mechanism to move at a high speed in the bent pipe under the action of the gas pressure; the limiting mechanism penetrates out of the bent pipe and then is meshed with the pre-tightening wheel, the limiting mechanism tightly clamps the pre-tightening wheel, so that the pre-tightening wheel is promoted to stop rotating, at the same time, the marble assembly is limited in the bent pipe. The pre-tightening type retractor preventing the open fire can limit the combustible gas in the bent pipe, prevents the high-temperature gas from spraying out to cause the open fire, at the same time, limits the shooting number of the marbles, and guarantees the stability and consistency of the pre-tightening amount.

Description

technical field [0001] The invention relates to the technical field of automobile safety belts, in particular to a pre-tightened retractor for preventing open flames. Background technique [0002] The seat belt retractor refers to the seat belt retractor with the emergency locking function, and the English name is EmergencyLockingRetractor, referred to as ELR. It is the core component of the car seat belt, and the retractor is the core component of the car seat belt. When the car encounters an emergency, the space for people to move and buffer is quite small. At this time, it is necessary to consider firmly fixed on the seat, and then through the force limiting device to minimize his injury. The pre-tensioning device ignites the gas generator within a few milliseconds through the collision sensor, and pushes the pull-back device to pull back the webbing, binding the person to the seat. At present, the main demand in the market is the pre-tight force-limiting retractor. Aft...
