Description

Height adjuster for automobile safety belt

Technical Field

The invention relates to the field of automobile safety belts, in particular to a height adjuster for an automobile safety belt.

Background

A vehicle seat belt is a device used in a vehicle to ensure that a passenger and a driver are protected from injury when the passenger is ejected from an airbag when the vehicle body is violently hit. The function of the automobile safety belt and its principle is to apply most of the stopping force to the thorax and pelvis, which are relatively strong. Since the part of the harness spanning the body is wide, the force is not concentrated in a small area and therefore does not cause excessive injury. Furthermore, the material used for the safety belt is much softer than the dashboard or windshield. It may stretch slightly, which means that the stopping process is not too abrupt. However, the harness should not be stretched too far, otherwise you may hit the steering wheel or side window. The harness only allows you to move forward slightly.

Traditional car blet highly generally is fixed the setting, consequently can't be applicable to the not use crowd of co-altitude when using, to the shorter people of stature, the car produces the danger that the cervical vertebra fracture and suffocation easily produce when colliding or emergency braking, and to the higher people of stature, can't effectively retrain passenger's health when violent striking, can cause human upwards sharp displacement, make the people head bump to roof or front windshield, consequently, in order to solve this type of problem, we have proposed a height adjuster for car blet.
