Background
According to ergonomic principles, the human spine shape can be divided into double "S" shapes, such physiological shapes enhancing flexibility of human activities. The spine is composed of vertebrae, including the cervical, thoracic, lumbar and sacrum (pelvic vertebrae) from top to bottom. The vertebrae constituting the cervical vertebrae, have the maximum range of motion. The vertebra of the thoracic vertebra is respectively connected with the ribs to form a thoracic cavity with higher rigidity, so that the internal organs of a human body are protected. The vertebrae of the lumbar spine connect the thoracic cavity and the sacrum and provide mobility to the lumbar region (lower back). While the sacrum is made up of fused vertebral segments connected to the ilium on the pelvis by sacral joints. In the lumbar region, the lumbar region is the most fragile and most protected region because of its strong mobility and support of most of the body weight (upper body weight) and the resistance to various shocks and vibrations (running, jumping, etc.) caused by the movement of the person. Once the lumbar spine has been removed from the "S" shape for some reason (the lumbar spine is essentially lordotic), the pressure between the vertebrae in the lumbar region (the intervertebral discs) increases rapidly, thereby increasing fatigue and pain, and prolonged incorrect posture of the lumbar spine can aggravate the lumbar spine and cause prolapse of the lumbar intervertebral disc.
Since the individual persons have different lumbar lordosis and different heights of lumbar vertebrae, a good sitting posture is required to reduce the stress on the lumbar intervertebral disc in order to maintain a good shape of the lumbar vertebrae during a long-term daily activity, and it is necessary to adjust the surface energy of the lumbar region of a seat (car seat, office seat, etc.), and the amount of protrusion deformation, height, etc. are different depending on the physical conditions of the individual persons. Therefore, lumbar support systems having adjustable lumbar support regions are of considerable importance.
