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.
Description
- 1. Field of the Invention
- The present invention relates to improvements of chair padding and more particularly to a chair (e.g., office chair) having both seat and backrest padded with foam rubber and adjustable air cushion so as to be adapted to users of different weights.
- 2. Description of Related Art
- Conventionally, the seat and the backrest of a chair (e.g., office chair) is padded with foam rubber or the like for providing the user with a degree of comfort while sitting thereon. One such office chair is shown in
FIGS. 1 and 2 . The chair comprises a seat 1 including asupport board 2, a pad 3 formed of foam rubber disposed on thesupport board 2, acloth 4 enclosed both thesupport board 2 and the pad 3 by stitching at the bottom of thesupport board 2, and aframe member 5 sandwiched between thesupport board 2 and a supporting framework 6 of the chair and threadedly secured to thesupport board 2. - In a case of a person sat on the seat 1, the pad 3 is compressed. However, the prior art suffered from several disadvantages. For example, the person may feel discomfort, particularly the vertebra, after a long period of sitting since the pad 3 is completely compressed to be very firm. Thus, the desired degree of comfort of sitting is compromised. Also, ventilation of the seat 1 is poor, especially in hot summer days. Thus, the need for improvement still exists.
- 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.
- It is another object of the present invention to provide a padding device mounted in an integral seat and backrest assembly 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, 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.
- The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

FIGS. 3, 4 , and 5, there is shown a first preferred embodiment of chair (e.g., office chair) according to the invention. The chair comprises aseat 10 and aseparate backrest 20. Each component of theseat 10 and thebackrest 20 will be described in detail below. As shown inFIG. 4 , theseat 10 comprises asupport board 11, apad assembly 12 disposed on thesupport board 11, thepad assembly 12 including apad 122 formed of foam rubber, an airtightfirst cloth 121 enclosed thepad 122, and avalve 123 projected from thefirst cloth 121, thevalve 123 having an inner end in communication with air within thepad 122, asecond cloth 13 enclosed both thesupport board 11 and thefirst cloth 121 by stitching at the bottom of thesupport board 11 in which thevalve 123 is further projected from thesecond cloth 13 for communicating with external air, and aframe member 14 sandwiched between thesupport board 11 and a supportingframework 31 of the chair and threadedly secured to thesupport board 11. Thepad 122 can be inflated by forcing air through thevalve 123. - As shown in
FIG. 5 , thebackrest 20 comprises asupport board 21, apad assembly 22 disposed on thesupport board 21, thepad assembly 22 including apad 222 formed of foam rubber, an airtightthird cloth 221 enclosed thepad 222, and avalve 223 projected from thethird cloth 221, thevalve 223 having an inner end in communication with air within thepad 222, afourth cloth 23 enclosed both thesupport board 21 and thecloth 221 by stitching at the back of thesupport board 21 in which thevalve 223 is further projected from thefourth cloth 23 for communicating with external air, and aframe member 24 sandwiched between thesupport board 21 and a vertically stationaryupright backrest support 32 attached to the supportingframework 31 and threadedly secured to thesupport board 21. Thepad 222 can be inflated by forcing air through thevalve 223. - Referring to
FIGS. 6 and 7 , in a case of a person sat on theseat 10, the person may adjust thevalve 123 by rotation to inflate or deflate thepad 122 until he/she feels a degree of comfort on the buttocks. In detail, a person having a heavier weight may adjust thevalve 123 to inflate the pad 122 (i.e., thepad assembly 12 becomes firm) for providing a strong support. Alternatively, a person having a lighter weight may adjust thevalve 123 to deflate the pad 122 (i.e., thepad assembly 12 becomes soft) for providing a weak support. In either case, air in thepad 122 under the buttocks is compressed to inflate other portions of thepad assembly 12. Such temporarily deformed pad assembly 12 (i.e., the top surface of thepad assembly 12 becomes curved) can provide the buttocks of the person with a degree of comfort while sitting on theseat 10. Advantageously, the weight of the person is supported by both air within thepad 122 and the pad 122 (i.e., similar to air cushion device). Hence, such comfortable feeling can last during the sitting. Also, heat generated on the buttocks during sitting can be absorbed by air within foam rubber of thepad 122. In other words, ventilation of theseat 10 is good. - Referring to
FIG. 8 , similarly, the seated person may adjust thevalve 223 by rotation to inflate or deflate thepad 222 until he/she feels a degree of comfort on the back. Air in thepad 222 against the back is compressed to inflate other portions of thepad assembly 22. Such temporarily deformed pad assembly 22 (i.e., the surface of thepad assembly 22 urged against the back becomes curved) can provide the back of the person with a degree of comfort while sitting on theseat 10. Advantageously, the back of the person is supported by both air within thepad 222 and the pad 222 (i.e., similar to air cushion device). Hence, such comfortable feeling can last during the sitting. Also, heat generated on the back during sitting can be absorbed by air within foam rubber of thepad 222. In other words, ventilation of thebackrest 20 is good. - Referring to
FIGS. 9 and 10 , there is shown a second preferred embodiment of chair (e.g., office chair) according to the invention. The second preferred embodiment substantially has same structure as the first preferred embodiment except that the seat and the backrest are integrally formed as an L-shaped member 40. The L-shaped member 40 comprises an L-shaped support board 41, an L-shaped pad assembly 42 disposed on thesupport board 41, thepad assembly 42 including apad 422 formed of foam rubber, an airtightfirst cloth 421 enclosed thepad 422, and avalve 423 projected from thefirst cloth 421, thevalve 423 having an inner end in communication with air within thepad 422, asecond cloth 43 enclosed thesupport board 41 and thecloth 421 by stitching at the back of thesupport board 41 in which thevalve 423 is further projected from thesecond cloth 43 for communicating with external air, and aframe member 44 sandwiched between thesupport board 41 and the supportingframework 31 and threadedly secured to thesupport board 41. Thepad 422 can be inflated by forcing air through thevalve 423. The second preferred embodiment substantially has same weight support and air cushion effects as the first preferred embodiment. - While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
