A pneumatic lumbar support device

Abstract

The invention discloses a pneumatic waist support device which comprises an air pump, air bags and deflation solenoid valves for controlling deflation of the air bags, wherein the air pump is connected with the air bags through two-position three-way normally closed and normally open solenoid valves; the air pump is communicated with air inlets of the two-position three-way normally closed and normally open solenoid valves; the air bags are communicated with exhaust ports of the two-position three-way normally closed and normally open solenoid valves; and the deflation solenoid valves are communicated with air outlets of the two-position three-way normally closed and normally open solenoid valves. According to the pneumatic waist support device provided by the invention, the air pump is used for supplying air to the air bags, and the two-position three-way normally closed and normally open solenoid valves and the deflation solenoid valves are used for controlling the inflation and deflation of the air bags so as to realize the volume change of the air bags and further adjust the size of the waist support, thereby adapting to the diversified demands of users and improving the comfort and applicability of the waist support.

Description

Technical field [0001] The invention relates to the field of automobile lumbar support equipment, in particular to a pneumatic lumbar support device. Background technique [0002] With the widespread use of automobiles, the comfort of car seats has become more and more important. Existing seats cause muscle fatigue to people's waists, which can easily cause spinal injuries, disease, and bending. [0003] The lumbar support in the prior art is generally made of materials such as space cotton. When used, the size change is small. The same lumbar support is generally only suitable for people of the same body shape and cannot meet the needs of popularization. [0004] Therefore, how to improve the comfort of the lumbar support while improving the applicability is a technical problem that needs to be solved by those skilled in the art. Summary of the invention [0005] The object of the present invention is to provide a pneumatic lumbar support device, which can adapt to the needs of vari...
