Description

CUSHION FORMING CURVATURE OF CERVICAL VERTEBRA AND THORACIC VERTEBRA [0002]

The present invention relates to a cushion that maintains the curvature of the cervical vertebrae and the thoracic vertebrae, and more particularly, to a cushion that maintains the curvature of the cervical vertebra and the thoracic vertebrae, thereby correcting the posture correctly and maintaining the curvature of the thoracic vertebra.

The spinal column is the central skeleton of the human skeleton, and acts as a supporting column for supporting and supporting the body. As shown in FIG. 1, the vertebrae is composed of the cervical vertebrae corresponding to the neck bone, the thoracic vertebrae corresponding to the backbone, the lumbar vertebrae corresponding to the backbone, and the vertebrae corresponding to the vertebrae and the vertebrae corresponding to the caudal bones.

In normal vertebrae, the cervical vertebrae (lumbar) and lumbar vertebrae (lumbar vertebrae) form the forward convexity (Lordosis), the thoracic vertebrae (chest) and the cervical vertebrae , Kyphosis). However, when the posterior curvature of the thorax is increased, not the normal shape of the vertebra due to abnormality of the vertebral body, intervertebral disc and surrounding muscles, or when the posterior deformation is seen in the neck and lumbar region, it is called posterior oblique.

The reason why the cervical vertebrae should be formed and the thoracic vertebrae should be formed is that the weight of the skull is relieved by the forward convex cervical vertebrae and the backward convexity is relaxed again in contrast to the cervical vertebra. Since humans are always gravitational, the body must be given less gravity to maintain a healthy life. Thus, the human thoracic vertebrae walking upright is formed opposite to the curve of the cervical spine to alleviate its gravity. And the curve should make the cervical vertebrae, thoracic spine, lumbar spine, and sacrum vertebrae balance in the spinal center line as a whole. This balanced S line of spine alleviates the gravity applied to the body.

When the cervical vertebra is either in or out, the center of gravity moves to the front of the vertebral body, the center of gravity moves over the nucleus, and the vertebral body is in an unstable position. In addition, when the thoracic spine becomes dated or transient, the center of gravity moves to the back of the vertebral body, the center of gravity moves over the nucleus, and the vertebral body becomes unstable. Therefore, it is important to correct the torsional angle of the cervical vertebra and the posterior aspect of the thoracic vertebrae as the tendency of the nucleus tend to move to the relatively weakly posterior region and consequently the nucleus lumbar disc herniation (neck disk) can easily be induced.
