Chair for pelvic correction {CHAIR FOR PELVIS CORRECTING}

The present invention relates to a pelvic orthodontic chair configured by mounting a backrest capable of supporting and maintaining the user's back organically even when the seat plate is rolled, as well as allowing the seat plate and the feet to return to their original positions depending on whether or not the user is seated.

Bone nodes are connected to the center of the human body, and if the alignment of the various vertebral nodes is not properly aligned, it can cause severe pain-related vertebral system diseases. That is, severe pain may occur due to nerve stimulation due to deformation of the spine or the relaxation and dislocation (prolapse) of the lumbar disc (disc) between the vertebrae, as well as fatal disorders such as paralysis of a part of the body.

In order to prevent and correct such spinal diseases, most of the seated people must consciously close their back to the back and tilt their upper body toward the back to achieve their intended purpose. If it is separated from, it will not have any special effect.

In recent years, as the amount of time spent sitting on a chair increases, the function of a chair that provides the best seating and comfort to the user during seating has become important and can relieve the user's fatigue even when sitting for a long time. It is improved in various forms, not just adjusting the height of the chair, adjusting the angle of the backrest, and rotating the seat plate.

In particular, the pelvis is an important part of achieving the whole body balance because it is a part that is connected to the lower body. If the pelvis is twisted, it may affect the flow of lymph or blood and cause serious illness. As the pelvis is displaced, the position of the bones may be deformed, making it difficult to maintain a balanced body such as a bent leg.

Therefore, in consideration of the physical condition of the users, research and development of a pelvic protection chair that can promote the user's pelvic health by setting a pair of pedestal spacings at a certain distance according to the pelvis spacing so that they can be moved up and down from the center have been researched and developed. have.

That is, in the backrest chair disclosed in Korean Patent Application Publication No. 2000-0066379, the seat portion is divided into first and second seats, and the user's fatigue can be alleviated by moving the first and second seats back and forth, left and right, and up and down. However, since the first and second seats freely move according to the user's body shape, there is a disadvantage in that the corrective effect of the pelvis and the spine connected to the pelvis cannot be sufficiently obtained.

In addition, in the case of the technologies disclosed in Korean Patent Nos. 0654918 (20061206 Announcement) and 1327884 (20131111 Announcement), the elastic members disposed on the lower sides of the left and right divided seats according to the load distribution according to the seating posture of the seated person Although the seat plate is hinged and rotates the pelvis, it is possible to exercise the pelvis, but it is somewhat weak in helping the back health by inducing the seated person's back to straighten, reducing the load and reducing the tension in the back muscles while maintaining a balanced posture. There is this.

On the other hand, among the conventionally known chair-related technologies, chairs that perform a tilting action while the seat plate slides forward so that the seat plate slides forward so that the seated posture can be straightened by straightening the waist of the seated seated seat as well as helping the waist health. It is disclosed.

For example, in the case of a chair disclosed in Korean Patent No. 1180482 or 1482738, the device itself for sliding the seat plate forward has a disadvantage in that it is structurally complicated, and it is a simple sliding structure, so that the lower back in a sitting position. It was only equipped with simple functions that could provide a healthy posture.
