Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile seat backrest with a detachable lumbar support. Background technique [0002] In modern society, with the improvement of people's living standards, more and more people own their own cars. However, when driving long distances, the waist is prone to fatigue due to sitting on the seat for a long time. In order to improve the comfort Usually, a lumbar support is installed on the back of the seat to adjust the degree of arching of the backrest, so that the waist of the person can be in close contact with the backrest without hanging in the air, thereby reducing or avoiding the fatigue of the waist.

The motor drives the steel wire to pull the plastic bracket of the lumbar support to deform to achieve the purpose of lumbar support adjustment, b...

AI Technical Summary

Problems solved by technology

[0004] 1. The motor drives the steel wire to pull the plastic bracket of the lumbar support to deform to achieve the purpose of lumbar support adjustment, but this method requires switches, motors, lumbar support body and wiring harness, etc., and the implementation cost is relatively high;

[0005] 2. Adjust the lumbar support by inflating and deflating the electric air pump, but this method needs to inflate and deflate the air bag fixed in the seat in advance, and needs a switch, electric pump, air bag and air pipe, etc. The implementation cost is higher than that of electric wire drive;

[0006] 3. It is adjusted by the manual lumbar support adjustment mechanism, but the adjustment effect of this method is not obvious, and the operation time is longer

[0007] In addition, the above three adjustment mechanisms must be assembled together with the seat back assembly, and individual customization cannot be completed, resulting in high cost of the seat back, and it is difficult to assemble and disassemble the lumbar support
