From a general point of view, point out the upright gait as a historical review of the lumbar spine disease. However, there is no problem with upright walking itself. By taking a standing posture, the pressing force of the spine and the disc (disk), which is received by gravity, is increased. Here, the pressing force applied to the vertebrae and the vertebrae varies greatly depending on the weight applied to the vertebrae and the shape of the curvature.

Among them, the sitting position of modern people occupies the most part of everyday life except sleeping time. In other words, except for occupational arm and physical movement (walking, running), standing posture, it is the most sitting time.

In addition, students, general office workers, transportation workers, workers working in a sitting position, and general service workers are in a sitting position for most of the day.

The compression force of the spinal column in the posture is an important factor for the health of the spine and the disc, as the pressing force of the intervertebral disc varies by up to 150% depending on the sitting position and the shape of the chair.

For this reason, decompression therapy devices and decompression devices designed as alternatives to lowering the pressure of the intervertebral disc due to pressure, or the pressure of the analogy site during daily life are being developed for therapeutic purposes. However, these devices have a disadvantage in that the treatment cost and the equipment cost are high, and the therapeutic effect is temporary and impractical.

The Korean Registered Utility Model No. 20-0399537, which was devised to solve the problem as pointed out, is a system in which when the seat is lowered while the upper body is fixed to the back plate while the seat is seated on the chair formed independently of the seat plate and the back plate, At the same time as relaxation, the pressure of the intervertebral disc is relieved, and the back pain or the neck disk can be improved by a quick and simple method.

However, the conventional art described above has a drawback in that power consumption is increased because a cylinder mechanism for lowering the seat plate and a separate power source for implementing the cylinder mechanism are required.
