Top-surface camber type air cushion, saddle, seat cushion, lazyback and manufacturing method of air cushion

Abstract

The invention provides a top-surface camber type air cushion, a saddle, a seat cushion, a lazyback and a manufacturing method of the air cushion. The top-surface camber type air cushion includes a seat surface and a bottom plate, wherein the seat surface is a flexible thin wall body, the periphery of the seat surface is connected to the bottom plate in a sealing mode, a curved surface constructionmatched with a human body is advantageously formed by the seat surface after inflating through arrangement of different wall thicknesses of all areas on the seat surface, force-bearing parts of the human body are fully matched, and the comfort level is improved. The lower part of the seat surface of the saddle is separated into a plurality of inflation air cavities by adopting a slice-type tie piece mode, thus the curved surface shape is maintained, the aesthetic degree is ensured, a rider can adjust the inflating plumpness of the inflating air cavities corresponding to all the areas according to postures, and riding experiences are improved.

Description

technical field [0001] The invention relates to the technical field of air cushions, in particular to a method for manufacturing an upper curved air cushion, a saddle, a seat cushion, a backrest and the air cushion. Background technique [0002] At present, the seat cushions or backrests of bicycles, electric bicycles, car seats, high-speed rail seats, aircraft seats, and wheelchairs are all made of foaming materials such as sponge or polyurethane. Once such seat cushions and back cushions are formed, their elastic properties cannot If it is changed again, the elasticity will be lost or weakened during use, and it will not be able to return to the original state, the comfort of use will become worse, and the service life will be short. There are also a small number of seat cushions with airbags on the market, but the airbags are embedded inside the main cushion body, which only play a role in supporting the human body locally, and cannot fully support the body's weight. When...

Problems solved by technology

[0002] At present, the seat cushions or backrests of bicycles, electric bicycles, car seats, high-speed rail seats, aircraft seats, and wheelchairs are all made of foaming materials such as sponge or polyurethane. Once such seat cushions and back cushions are formed, their elastic properties cannot If it is changed again, the elasticity will be lost or weakened during use, and it will not be able to return to the original state, the comfort of use will become worse, and the service life will be short

There are also a small number of seat cushions with airbags on the market, but the airbags are embedded inside the main cushion body, which only play a role in supporting the human body locally, and cannot fully support the body's weight. When the elasticity of the main cushion body surrounding the airbag weakens After that, the user's comfort becomes worse

The biggest difficulty of using a single-body air cushion is that the curved shape of the upper layer is difficult to maintain stability after inflation, and it cannot be well adapted to the force point, which greatly affects the sitting experience
