Automobile safety belt lock tongue

Abstract

An automobile safety belt spring bolt is provided with a self-locking sliding block, the self-locking sliding block is installed on a spring bolt body in a sliding mode, the self-locking sliding block can be close to a holding portion of the spring bolt by sliding along the spring bolt body, and the end face, opposite to the holding portion, of the self-locking sliding block is provided with a meshing portion. A gap between the holding part and the occlusion part is called as a first gap; the self-locking sliding block is provided with a check block, and a safety belt braid penetrates in from the first gap, bypasses the check block and then is folded back. When the braid is tightened, the braid drives the self-locking sliding block to slide towards the holding part through the check block, so that the first gap is shrunk until the braid is meshed to the holding part through the meshing part, the locking function of the spring bolt on the braid is enhanced, and the situation that injury to the chest and shoulders of a passenger is aggravated when an automobile collides is avoided.

Description

technical field [0001] The present application relates to the technical field of seat belt structures in automobile parts, in particular to a car seat belt latch.

Problems solved by technology

[0005] This application provides an automobile safety belt lock tongue to solve the problem that the locking function of the lock tongue on the ribbon is not strong during the collision of the existing automobile. The embodiment provided by the application is that when the ribbon is tightened, the ribbon passes through the barrier The block drives the self-locking slider to slide towards the holding part, so that the first gap is narrowed until the occlusal part bites the webbing to the holding part, so as to strengthen the locking function of the deadbolt on the webbing
