Description

Support lumbar cushion

This creation is related to a kind of lumbar support cushion, especially the seat cushion which can gently lift the buttocks, or a recessed cushion formed according to the characteristics of the human buttocks, and can naturally make the cushion when pressing the body on both sides of the buttocks. The posterior and connected lumbar support are pushed to the lumbar vertebrae and the spine to maintain a correct sitting position while relieving lumbar pain and allowing the user to remain seated for long periods of time.

Generally, the seat cushion does not use the material that can gently support the buttocks, and can not maintain the physiological curvature of the spine. Therefore, in the sitting position where the two feet are naturally ground, the pelvis that the user leans forward causes the tailbone, the tibia and the spine to bend backward. , causing the spine to lose its physiological curvature and form a state of posterior curvature of the spine. In this state, the weight of the upper body of the user is all pressed against the tailbone, the periphery of the ischial bone, the lower lumbar vertebrae, the lumbar disc and the back of the thigh, thereby increasing the burden on the waist or the tailbone.

Furthermore, because people are accustomed to sitting in a leg-sitting position, the burden on the periphery of the ischium is more severe, resulting in an imbalance of the upper body, which causes bone deformation.

The curved portion 903 is composed of a front locking device 904 and a rear locking device 905, and the feature enables the user to improve the sitting posture and make the seat cushion A become a Auxiliary chair.

When sitting on the auxiliary chair, it will prompt the person's legs to unfold and not easily raise the leg. On the basis of the balance of the legs, the upper body is distracted to induce the pelvic anterior curvature and the physiological curvature of the spine. The periorbital bone, the lower lumbar vertebra or the intervertebral disc, the thigh The gravity in the back can not only exercise the legs but also reduce the pressure on the waist and the tailbone, and it is not easy to form the pelvic back bend structure, which can prevent the user from being in the back bend of the spine for a long time, so that the user can maintain a good sitting posture. When sitting on a flat chair or on the ground, the auxiliary chair with the central part in the recessed state can maintain the stability of the pelvis and the correct sitting position to protect the health of the spine.

On the other hand, the pelvis includes a waist composed of funnel-like bones, a fifth lumbar vertebra, a tibia, a coccyx, and left and right hip bones. Therefore, the auxiliary chair can maintain the correct sitting posture while supporting the pelvis, but when there is no cushion A, there is no feeling of comfort, and since the lumbar vertebrae cannot be supported, the lumbar vertebra disease can still be induced when sitting for a long time.
