Air bag type support system of seat

Abstract

An air bag type support system for seat is composed of an air valve assemblage with main and branch air channels, supporting valves and one-way valves, at least one inflating pump, at least one supporting air bag group and a controller for controlling the inflation or air release of said air bag group.

Description

technical field [0001] The present invention is a changing system which is installed on the seat to make the seat produce supporting effect through the expansion and deflation of the air bag, and can cooperate with the setting of the massage unit to make the seat have the functions of support adjustment and massage. Background technique [0002] At present, most of the seats with adjustable support effect on the market adjust the curvature and convexity of the seat surface through the linkage of mechanical devices such as motors, gears, racks or screws, so as to further enable the occupants to To obtain a more comfortable support effect, for example, in the seat design of more advanced cars, most of them will adjust the support degree of the seat by setting a mechanical device. [0003] However, the aforementioned traditional mechanical transmission methods often have uneven force or the mechanical device embedded in the seat is too rigid, resulting in uncomfortable riding, ...

Problems solved by technology

[0003] However, the aforementioned traditional mechanical transmission methods often have uneven force or the mechanical device embedded in the seat is too rigid, resulting in uncomfortable riding, and relatively increasing the total weight of the seat, which is different from the automotive industry. Going against the idea of ​​lightweight

And when the user exerts a large pressure or impact force on the seat, in addition to the wear and tear of the mechanical device due to the reverse leverage, when the mechanical device fails and does not operate according to the user's control, it is likely to Undue pressure on the user's back, neck, waist or legs due to excessive changes in the curvature and curvature of the seat

[0004] Furthermore, when the vehicle collides or brakes suddenly, because the traditional mechanical transmission method is too rigid, it is easy to cause undue local impact on the occupants, and even possible accidental injuries
