Description

Pelvic correction chair

[0001] The present invention relates to a pelvic correction chair, and more specifically, to a pelvic correction chair that corrects pelvic misalignment by adjusting the left and right angles of the chair seat to make the pressure applied to the pelvis of the seated person different.

[0002] Scoliosis is a condition in which the spine appears to curve sideways when viewed from the front, causing the pelvis and shoulders to be at different heights or the torso to appear tilted to one side. An X-ray can reveal the spine to be curved sideways. Lower back pain is the most common symptom in patients with scoliosis, and the primary cause of the pain is a misaligned pelvis.

[0003] Recently, as the amount of time spent sitting has increased, the number of patients with scoliosis due to poor posture or habits has increased significantly. In particular, adolescents are more likely to have spinal curvature due to poor posture while their bones are still growing than adults.

[0004] Scoliosis treatment primarily involves pelvic correction devices and scoliosis correctors, which aim to prevent spinal and pelvic misalignment and correct deformities. However, scoliosis correctors are difficult to use in everyday life due to their size and complex application.

[0005] To solve these problems, various technologies have been developed recently to correct the spine and pelvis while sitting in a chair by grafting a scoliosis correction device that maintains correct posture onto the chair where one spends most of one's time in daily life.

[0006] Patent No. 10-2606537, "Chair for Correcting Lumbar Curvature and Pelvic Horizontal Position," discloses a seat cushion having at least one variable volume formed on the upper or lower portion of a seat body that supports the lower body of a seated person, performing a cushioning function. The above-mentioned patent has a problem in that it is difficult to control the pressure applied to the pelvis by changing the volume of the seat body by allowing air in and out.

[0007] Patent No. 10-2624184, "Body Correction Chair," discloses a body correction chair that corrects the body shape of the user's pelvis, spine, etc. by causing the chair cushion, which supports the user, to rotate (circumduce) by a circular rotating part while being tilted by a main motor, control part, and link part of a connecting device. The above-mentioned patent has a disadvantage in that the configuration of the device for adjusting the inclination of the chair cushion is complicated.

[0008] Typically, pelvic correction involves identifying the pelvic misalignment using X-rays or a pelvic tilt meter, then raising the angle of the pelvic seat on the opposite side of the elevated pelvis. However, fine-tuning the seat during pelvic correction can be difficult, and angle adjustment can be complex.
