Benefits of technology

[0006] It is an object of the present invention to provide a padding device mounted in each of a seat and a backrest of a chair, comprising a support board; a pad assembly secured on the support board, the pad assembly including a pad formed of foam rubber, an airtight first cloth enclosed the pad and the support board, and a valve projected from the first cloth for communicating air within the pad and external air; a second cloth enclosed the pad assembly with the valve being projected therefrom; and a frame member secured between the pad assembly and a supporting framework or a vertically stationary upright backrest support attached to the supporting framework, wherein air within the pad is adapted to increase or decrease by adjusting the valve in response to pressing either the seat or the backrest. By utilizing the present invention, a number of advantages are obtained. For example, the temporarily deformed pad assembly can provide the buttocks and the back of a seated person with a degree of comfort. Also, the weight of the person is supported by both air within the pad and the pad itself similar to air cushion device. Moreover, heat generated on the buttocks or the back during sitting is substantially absorbed by air within foam rubber of the pad.

Problems solved by technology

However, the prior art suffered from several disadvantages.
Thus, the desired degree of comfort of sitting is compromised.
Also, ventilation of the seat 1 is poor, especially in hot summer days.

Abstract

A padding device mounted in each of seat and backrest of a chair is disclosed. The device comprises a support board and a pad assembly secured between the support board and a supporting framework or a vertically stationary upright backrest support attached to the supporting framework, the pad assembly including a pad formed of foam rubber, an airtight cloth enclosed the pad and the support board, and a valve projected from the cloth for communicating air within the pad and external air. Air within the pad is adapted to increase or decrease by adjusting the valve responsive to sitting by a person. In another configuration the seat and the backrest are integrally formed. The temporarily deformed pad assembly can provide the buttocks and the back of a seated person with a degree of comfort by sharing weight of the person by both air within the pad and the pad.
