In general, many people live in the home, school, workplace, restaurant, and the like, and use the private or public transportation when moving. Most people inevitably use the chair in the above-mentioned place. That is, the proportion of the chair occupied in daily life is considerably high as most of the living is with the chair. Therefore, most people are demanding a more comfortable and comfortable chair when seated, and they are also demanding a chair that is beneficial to health by improving living standards.

The basic form of the chair is composed of a seat for supporting the buttocks and the thighs of the seated person, a backrest for supporting the backrest of the seated person at the end of the seat, and an armrest for resting the seat of the seated person.

The seat can be used as a cushion when the seat is placed on the floor and the cushioning material is built in. When a seat back is installed on the seat, And can be used as a general chair when the seat is placed on a frame.

As a conventional example, a chair frame of Korean Utility Model Registration No. 20-0202405 is presented as an example.

The chair is a chair which can disassemble and assemble a chair frame to minimize the volume of the chair when storing and transporting the chair. In each of the frames constituting the chair is made of steel, And a bolt is fastened in the bolt hole to connect the frames.

In the above case, since the component parts are made of a metal material, there is a problem that they are difficult to be assembled as well as being transported, and it is difficult to provide a comfortable cushioning force to a user at the time of use after assembly.

As another example, a functional cushion for a backrest of Korean Utility Model Laid-Open No. 20-2010-0011743 has been proposed.

In this case, a cushioning member is formed inside the cover formed in the outside, and a separate bag is formed at the rear of the backrest to serve as a cushion of the backrest, and a back pocket is formed in the backrest.

In other words, the seat backrest cushion is configured to provide comfort to the portion of the seat backrest contacting with the backrest, and a cushion is formed on the opposite side of the seat cushion against the back of the seat so that the cushion can be easily inserted into the seat backrest .

However, the above-mentioned cushion is used by being inserted into the back of the chair when needed, and thus the appearance is not good when applied to the backrest of the chair.

Korean Patent Registration No. 10-1310154 discloses a chair assembled with a plurality of assembly supporting plates.

Since the plurality of assembly support plates are inserted and fixed on the seat plate and the backrest of the chair frame in which the basic framework of the seat plate and the backrest is formed, the number of the assembly support plates installed on the seat plate and the backrest can be increased or decreased. The width of the chair and the height of the backrest can be adjusted according to the width of the backrest and the height of the backrest, so that if the size of the chair frame is deformed, the width and height of the chair can be arbitrarily adjusted. It is possible to provide a chair of the most appropriate size considering the size of a room, to quickly produce a chair, and to develop a chair for developing a chair.

However, there is a problem that assembly is difficult in the above case, and the cushion force of the seat back or the back is weak, so that it is difficult to provide comfort to the user.
