A car seat height adjustment structure with anti-sinking function in collision

Abstract

The invention discloses a car seat height adjustment structure with anti-sinking function in collision. By setting the anti-sinking device, when the height of the car seat is adjusted, since all the stoppers are in the retracted state, each A stopper will not hinder the movement of the limit shaft in the limit groove according to the circular arc track, so as to ensure that the height of the car seat can be adjusted normally; and after the height adjustment of the car seat is completed, if the car collides with the rear, Under the action of the occupant's downward impact on the car seat, the limit shaft begins to sink together with the seat cushion. Since the stoppers that do not interfere with the position of the limit shaft are all in the extended state, the limit shaft that begins to sink is affected. The stopper located below it is blocked, and each stopper below is plastically deformed until it breaks in turn, so as to buffer the sinking movement of the limit shaft, so as to prevent the seat cushion from suddenly sinking rapidly during the collision, and reduce the occupant's impact on the collision. damage suffered.

Description

technical field [0001] The invention relates to a car seat, in particular to a car seat height adjustment structure with anti-sinking function in collision. Background technique [0002] With the development of the automobile industry, the passive safety performance of automobiles is constantly improving. As one of the key components of automobiles, car seats not only require reasonable layout and ensure riding comfort, but also need to focus on ensuring and improving their safety performance. For example, in the automotive industry, many corporate technical standards strictly stipulate the performance requirements that seats need to meet during dynamic collisions, especially rearward impacts. [0003] Since the height of the seat cushion of the car seat is adjusted through the mutual engagement between the output gear of the height adjuster on the side plate 1 of the seat cushion and the tooth plate on the connecting rod bracket, as the main form of road traffic accidents, ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a car seat height adjustment structure with an anti-sinking function during a collision, so as to solve the problem that the seat cushion suddenly breaks due to the broken teeth of the tooth plate in the rear-end collision of the existing car seat. rapid sinking problem
