Automotive back seat restraint system test bed

Abstract

The invention discloses an automotive back seat restraint system test bed, comprising a sliding table as well as a front seat fixing unit and a back seat fixing unit arranged on the sliding table, wherein a support assembly is arranged beside the back seat fixing unit, the back seat fixing unit comprises an upper bottom plate and a lower bottom plate fixed with the upper bottom plate, and an anti-dive plate, a lock catch installing rack and a safety belt fixing block are fixed on the surface of the upper bottom plate. By adopting the technical solution, the front and back seat fixing units and supporting assemblies are arranged on the sliding table, the position of a test dummy is adjusted to the relative state of a real automobile, the relative position of a back seat passenger space is guaranteed to be consistent with the design state, a passenger restraint system can be verified before a soft mode is started in the body, the matching problem of the restraint system and the design problem of parts are discovered in time at the early stage of automotive model development, the rectification risk of the soft mode body is reduced, and thus the development period is shortened and the development cost is reduced.

Description

technical field [0001] The invention belongs to the field of automobile safety performance testing, and in particular relates to a universal test bench for restraint systems of rear-seat automobiles. Background technique [0002] Cars are becoming more and more popular as a modern means of transportation, and traffic safety issues have also received more and more attention. As one of the important contents of traffic safety, the development of vehicle occupant restraint system is particularly important. In the prior art, in the development stage of the vehicle occupant restraint system, the main engine factory generally adopts the body-in-white reinforcement method to simulate the vehicle structure, installs relevant interior parts on the body-in-white, and conducts dynamic simulation tests on the trolley. The restraint system is matched and developed by simulating the crash conditions of the whole vehicle. In the prior art, the test must be carried out after the developmen...

AI Technical Summary

Problems solved by technology

Before the development of the soft film body is completed, due to the inability to carry out effective test verification on the restraint system of the whole vehicle, there will be risks of rectifying the configuration of the restraint system and even the soft film body in the later stage, which will lead to the extension of the development cycle and the increase of development costs
