Active Seat Support {ACTIVE SEAT SUPPORT}

The present invention relates to an active seat support, and more particularly, to evenly distribute the pressure applied to the part of the body of the seated person, maintain a stable support surface against the load acting biased to improve the comfort when sitting, body fatigue And it relates to an active seat support that can prevent injuries.

Generally, a chair has a seat that mainly supports the vertical load of the seated person and a backrest that mainly supports the horizontal load.

The seat may be made of a simple plate structure formed by molding or assembling a synthetic resin or a metal plate in the case of a low-cost chair, and the seated buttock and the thigh may be strongly pressed when the seat is seated on a hard-faced seat, as described above. The pressure is concentrated in the convex area, which results in less comfort when seated and fatigue and pain in a short time.

In order to improve the above-mentioned disadvantages, a chair having a cushioning material such as a porous resin, a foamed resin, or a spring is used. Since the seat deforms and supports the load while the seat is deformed by the elasticity of the cushioning material when a person sits, the fatigue and discomfort felt when sitting is reduced.

However, since the conventional seat is a structure in which the load is distributed and supported only by the deformation of the cushioning material, the entire support surface of the seat moves in the load direction irrespective of the magnitude of pressure acting differently according to the shape and position of the body part in contact. Compression occurs.

As a result, it is better than a rigid plate-like sheet, but lacks a dispersing effect on the pressure applied to the body parts, so that a strong pressure is concentrated on some parts of the body, resulting in less comfort when seated and the body such as the spine or pelvis. There was a problem that adversely affects health by causing abnormalities.

In addition, if the position of the person sitting on the seat is not correct and the load on the left and right parts of the body is different, the pressure is concentrated only on the portion where the relatively strong load is applied, and the support surface of the seat is inclined, which increases the inconvenience of the seated person. There was a problem that adversely affects the physical health.

The present invention is to solve the problems as described above, to evenly distribute the pressure applied to the body parts of the seated person, to maintain a stable support surface against the load acting biased to improve the comfort when sitting, It is an object to provide an active seat support that can prevent fatigue and injury.
