Description

Chair for posture correction {Chair for keeping a straight posture}

The present invention relates to a posture-correcting chair, and more particularly, to an office chair comprising a seat plate supporting the hips and thighs and a back back supporting the waist, the hips being pushed toward the front of the seat to prevent the waist from bending. The support member that can support the inner thigh or lower abdomen so as to relate to a chair for posture correction installed in the middle of the upper surface of the seat plate.

Since humans live in an upright position against gravity, they always have spinal problems. In order to minimize such spine problems, the gravity should be sustained by appropriately dispersing the gravity up, down, front and back. This is because most spine problems are caused by incorrect bending of the spine with concentration of gravity due to bad posture. Therefore, if you leave the bad posture and the curve of the wrong spine for a long time, it puts a burden on the muscles, skeleton, ligaments and intervertebral discs, so that back pain, disc disease, scoliosis, lumbar lordosis, thoracic vertebral disease, neck and shoulder pain, chronic fatigue Cause.

Therefore, the right posture should be the first priority to prevent such spinal diseases. The correct posture is that the spine is upright while maintaining the natural spine curvature. For example, curvature of a normal spine means that there is a moderate curvature of the neck and waist toward the front, and a curve of an appropriate angle toward the back of the back and tailbone. Maintaining the normal curvature of the spine equalizes the force exerted along the vertebrae. However, the curvature of the spine is severe, or the curvature is inverted or straight waist is not able to disperse gravity, but if it is concentrated only in one place will cause physical burden on the muscles, ligaments and spine causing spine problems.

Therefore, office workers who sit for a long time in the office can cause various spine problems if the sitting position is not correct. Accordingly, recently, functional chairs have been developed that allow the position of the backrest and seat plate to be changed according to the user's body shape or separately install a neck or waist rest. However, even when using the functional chair, if the user does not sit upright, as shown in Figure 1, as shown in Figure 1, during the unconscious or prolonged operation, the hips are pushed to the front of the seat plate and the lower back is bent, lower back pain, disc disease Spinal disorders such as lumbar lordosis, neck and shoulder pain, and chronic fatigue.

The present invention has been made in view of such circumstances, and the main purpose of the present invention is to provide an inner thigh (groin) or lower abdomen in the middle of the upper surface of the seat so as to prevent the hips from slipping forward of the seat during unconscious or prolonged work. By providing a support member to support the back and hips to be in close contact with the backrest to provide a chair for posture correction so that the user can always sit in the correct posture.

The present invention also provides a posture correction chair that can freely adjust the position of the support member according to the user's body by providing a predetermined slide means on the support member.

In addition, the present invention is provided with a predetermined rotating means to the support member so that the support member can be rotated to the lower side of the seat plate when not using the support member for posture correction that does not cause inconvenience when the user sits or rises in the chair To provide a chair.
