Safety belt lock tongue

Abstract

The invention discloses a safety belt lock tongue. The safety belt lock tongue comprises a lock tongue body, a return mechanism and an adjusting rod; the lock tongue body comprises a lock tongue basebody and a lock tongue housing which coats the lock tongue base body; the return mechanism is mounted on the lock tongue body in a rotatable manner; the adjusting rod is fixedly connected with the return mechanism and obtains a return tendency through the return mechanism; as the connecting mode between the return mechanism and the adjusting rod is simple, and the return mechanism and the adjusting rod are arranged on the end side of the lock tongue body, the assembling of the return mechanism and the adjusting rod are made convenient, and the machining difficulty is also reduced; in a workingposition, a safety belt penetrates through a gap between the lock tongue body and the adjusting rod, the safety belt bypasses the adjusting rod, generates a pull force to the adjusting rod and drivesthe adjusting rod to rotate to a clamping position, the adjusting rod abuts against the safety belt so that the safety belt is clamped between a convex part of the adjusting rod and the lock tongue body; and therefore, the safety belt is fixed in a clamping position according to needs to prevent sliding between the safety belt and the lock tongue so that the binding effect of the safety belt is improved, and the safety protection performance of the safety belt is improved.

Description

technical field [0001] The present application relates to the technical field of automobile equipment, in particular to a seat belt lock tongue. Background technique [0002] Seat belt is an important car safety equipment, its function is to fix people on the seat during a collision, reducing the possibility of casualties. The seat belt is worn obliquely on the occupant's chest and horizontally on the occupant's waist. Wherein, one end of the seat belt is pulled by the lock tongue, and needs to be inserted into the buckle during use. [0003] The connection between the existing safety belt and the dead bolt is that the safety belt simply walks around the safety belt passage hole provided on the dead bolt, and the dead bolt provides a simple pulling force for the safety belt. The connection between the lock tongue and the seat belt is very simple, but the obvious problem is that when a collision occurs, the human body will produce a forward impact due to inertia, and the se...

AI Technical Summary

Problems solved by technology

The connection between the lock tongue and the seat belt is very simple, but the obvious problem is that when a collision occurs, the human body will produce a forward impact due to inertia, and the seat belt will bear The impact force is very large. Under the action of this impact force, the seat belt will slide relatively at the position of the seat belt passing hole of the lock tongue, loosening the restraint on the human body, thereby significantly reducing the safety protection effect on the human body.
