Chair having shape memory sponge mounted on backrest

Abstract

A chair having a shape memory sponge mounted on a backrest is invented that comprises a seat, a backrest, and a set of leg portions for supporting the seat and the backrest. The backrest includes a set of cut holes formed vertically to a given depth at both sides with respect to the center portion of the front surface thereof. A backrest cushion is inserted into each of the cut holes so as to protrude a given distance toward a user's back. The backrest cushion is formed of the shape memory sponge, and a fixing plate mounted at the rear side of each of the cut holes.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a chair, and more particularly, to a chair having a shape memory sponge mounted on a backrest that can safely protect a user's spine and can be used by all people irrespective of their personal physique.[0003]2. Related Prior Art[0004]Generally, a chair, which is a piece of furniture for a user to sit on in their home or office, includes a seat for supporting the user's hips, a backrest connected to the seat to support the user's back, and a leg part for supporting the seat and the backrest.[0005]Thus, the chair has been considered to be a tool on which a user can comfortably rest his or her body when he or she studies or works, but recently, it is considered to be a piece of furniture providing energizing and supportive feelings to the user so that he or she can obtain high study or work efficiencies. As a result, there have been proposed ergonomic chairs having a seat, a backrest, and ...

AI Technical Summary

Benefits of technology

[0008]Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a chair having a shape memory sponge mounted on a backrest wherein the backrest is provided with the shape memory sponge mounted on a portion abutting the user's spine, thereby safely protecting his or her spine and further making him or her feel comfortable while sitting thereon.

[0009]It is another object of the present invention to provide a chair having a shape memory sponge mounted on a backrest wherein the shape memory sponge of the backrest abutting with a user's spine is improved so that even if the user moves in every direction, good contacting forces of the shape memory sponge with the user's spine are obtained.

[0010]It is still another object of the present invention to provide a chair having a shape memory sponge mounted on a backrest wherein the backrest is rigidly formed, without having any deformation, thereby preventing the backrest from being easily broken or damaged.

Problems solved by technology

However, the conventional chairs have a generally semi-circular backrest, which fails to safely support a user's spine and back, thereby making him or her feel uncomfortable while sitting thereon.

Alternatively, they have two separated backrest portions, which unnecessarily makes the volume of the chair bulky, thereby decreasing the space utilization efficiency in an office and making the backrest portions easily broken.
