Description

[Detailed explanation of the invention] This invention maintains the spine in a normal state by interposing it between the object supporting the back and the back when sitting, for example, between the backrest and the back when sitting on a chair. To provide an orthodontic back support that can correct the condition and also provide an acupressure effect at a simple and inexpensive price.

The present invention consists of a pressing ridge A and a cushion body B. The pressing ridge A has a support leg 3 suspended from the bottom of a thick gutter shape 2 whose upper part has an appropriate waveform unevenness 1. On the upper part of the inner surface, projections 4 are provided symmetrically at appropriate intervals. It is desirable that the tips of the protrusions 4 be rounded to avoid excessive stimulation.

On the other hand, the cushion body B has a gentle concave surface on the upper surface of a substantially flat cube to stabilize the back, and a vertical groove 5 is bored in the approximate center of the concave surface, and the cushion body B is pressed against the groove 5 of the cushion body B. It has a structure in which almost the entire support leg 3 of the ridge 5 and the continuous gutter shape 2 are fitted and integrated, and the material of the cushion body B is made of a relatively soft elastic material such as urethane foam, sponge, or sponge. This relates to the structure of an orthodontic back support, characterized in that the pressing ridges A are made of an elastic material that is slightly harder than the material of the cushion body B, such as synthetic rubber, plastic, or natural rubber. be.

The present invention has the above-mentioned structure. For example, the horizontal bottom surface of the cushion body B of the present invention is applied to the back of a chair, and the present invention is interposed between the back and the back, and the gutter shape 2 is attached to the lower thoracic vertebrae and upper lumbar vertebrae of the human spine. If they touch each other, the gutter shape 2 will come into contact with the vertebrae in such a way as to wrap around them, and the protrusions 4, 4, etc. protruding from the upper left and right sides of the inner upper part of the gutter shape 2 will extend from the upper lumbar vertebrae to the lower thoracic vertebrae. The cushion body and the elastic material of the pressing ridges change the strength of the acupressure effect depending on the movement of the body.

Since the cushion body B of the present invention is molded from a relatively soft elastic material such as foamed urethane foam, it can be deformed according to the body shape of the person using it, and can be used by people of any body shape. It has the feature that it can be easily inserted not only in the sacrum, coccygeal bone, or vertebral column.

In addition, since the pressing ridge A is made of synthetic rubber, etc., which is harder than the cushion body B, the trough shape 2 presses the vertebrae as if pinching them from the left and right, resisting the distortion of the vertebrae and trying to maintain its shape in the vertical direction. It is useful for correcting the spine by correcting the spine so that it becomes straight, and further by widening the abnormality in the intervertebral foramen of the spine as if the waveform unevenness 1 and the protrusion 4 impact the abnormality in the spinal part with fingers.

People who drive a car for long periods of time use both legs to operate the accelerator, etc., and operate the steering wheel while supporting the entire body weight only on the lower back, which puts a lot of stress on the spine, causing spinal curvature and intervertebral spaces. Many of them have abnormalities in the intervertebral foramen, but the cause of all the kidney diseases, gastrointestinal diseases, etc. that these people suffer from is abnormalities in the intervertebral foramen. By using the present invention to correct the spine, it is possible to enhance its natural healing ability.

This device is extremely useful as a corrective backrest because it combines the soft elasticity of the cushion body B with the somewhat hard elasticity of the pressure ridges A, and the curved portion of the groove shape 2 acts as a powerful spring, enhancing the finger pressure effect of the protrusions 4 and the vertical correction effect of the spine.

The entire surface of the cushion body B may be covered with leather or the like. Further, reference numeral 6 indicates a cavity, which may be bored in order to further enhance the elasticity of the pressing ridge A.
