Automobile seat height adjusting structure with anti-sinking function in collision

Abstract

The invention discloses an automobile seat height adjusting structure with an anti-sinking function in collision. By arranging the anti-sinking device, when the height of an automobile seat is adjusted, due to the fact that all the check blocks are in a retracting state, each check block cannot hinder movement of a limiting shaft in a limiting groove according to the check track, and it is guaranteed that the height of the automobile seat can be normally adjusted; and after the height adjustment of the automobile seat is completed, if rear-end collision of automobile occurs, under the action of a downward impact force of a passenger on the automobile seat, the limiting shaft starts to sink along with the cushion. The check blocks which do not interfere with the limiting shaft in position are all in an extending state, the limiting shaft which begins to sink is blocked by the check blocks located below the limiting shaft, the check blocks below the limiting shaft are plastically deformed in sequence until the check blocks are broken, so that the sinking movement of the limiting shaft is buffered, the cushion is prevented from suddenly and rapidly sinking in the collision process, and injuries to passengers in the collision process are reduced.

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
