Description

Chair {THE CHAIR}

The present invention relates to a chair, and more particularly, when used as a normal backrest chair in normal times, when the fatigue of the spine is felt, the upper body is bowed forward to support the upper body to relieve the fatigue of the spine, while the shoulder to one side It relates to a chair that prevents bias and posture inherently.

In general, chairs are one of the oldest forms of furniture, with a dictionary meaning of "a seat with a backrest made for one person," which began to be used since the third Egyptian dynasty (c. 2686-2613).

Legs of early Egyptian chairs were generally similar to those of animal legs, and seating areas were corrugated or hollowed out of wood and padded or cushioned over them. Until recently, technologies related to materials, materials, and structures related to chairs have been continuously developed. Recently, chairs that do not overwhelm the spine even when seated for a long time based on ergonomic design have been developed.

That's because most people stand or sit outside of their sleeping hours, and the disks in their backs are forced to continue to be pressured by the weight of their torso, and when they are sitting in chairs and reading or working for a long time, they bow their heads forward. In many cases, sitting in a chair for a long time in such a bent position can cause pain in the disc and flexion of the spine due to tension in the lower back muscles.

In the related art, many chairs have been developed to reduce pressure on the disk of the lower back or correct the posture. In brief, the shape can be used to correct the position of the lower back using the curve of the hip and spine or to lie down halfway by tilting the back of the back. Chair is the mainstream.

Such a chair can reduce the pressure applied to the disk of the waist or reduce the pressure applied to the disk. However, when sitting in a chair for a long time while reading a book or working, it is difficult to maintain a correct posture, and thus the posture cannot be corrected. There was a limit to ease.

For example, it is possible to correct the posture of the waist by utilizing the curves of the hip and spine, but it is impossible to correct the posture of the shoulder more than the skew, rather there was a problem causing scoliosis and shoulder pain.

More recently, in order to solve the problem of the conventional chair, a chair having an upper body support capable of supporting the front of the chair, that is, the abdomen and the chest of the seater has been introduced, but such a chair is used for other tasks such as office work. If you see or work on the computer there is a difficult problem.

In addition, when the abdomen and the chest are supported by the upper body support for a long time, there is a problem that the pain occurs in the abdomen and the chest or feel stuffy. This is because the abdomen and chest are supported by the spine and the support base is weaker than the waist.

In addition, as described above, when the abdomen and the chest are supported for a long time, the entire front of the image is very wrinkled, there is a problem that can not be conscious of the eyes of others when interpersonal relationship.

The present invention created to solve the above problems is usually used as a normal backrest chair when the fatigue of the spine is felt, while the upper body is bowed forward to support the upper body to relieve the fatigue of the spine, while the shoulder to one side It aims to provide all the chairs used for furniture, office, and business, which can prevent the skewing of the posture at the source.
