Abstract

PURPOSE: A seat and a chair with a partial cushion is provided to distribute the pressure, given to the ischiadic tuberosity of hips, to the other area of the hips, so that the blood circulation of a user is promoted. CONSTITUTION: A cushion member is inserted in a groove of a seat(12), and consists of a first elastic material(23), a second elastic material(22) and a skin(21). The first elastic material is pressed by the ischiadic tuberosity of a user. The elasticity of the first elastic material is lower than the second elastic material, so that the pressure by the ischiadic tuberosity is transferred to the second elastic material. The skin surrounds the elastic material. Therefore, the pressure is distributed uniformly to the whole hips, so that the user is prevented from feeling hard on user's hips for a long time.

Description

Seat and chair with a partial cushion {seat and chair with a partial cushion}

The present invention forms a groove in a part of the seat plate in which the buttocks are placed when seated on a chair or a seat and a cushion member is formed in the groove, so that the seat and chair are partially mounted with a cushion so as to disperse the pressure acting on the buttocks. It is about.

In general, chairs and seats used in offices or schools are used to provide a flat surface or some curved surface for the purpose of distributing pressure, or to attach a cushion member having a uniform elasticity to the seat. Most of the pressure exerted by the upper body at the time of sitting is supported by the buttocks, and the greatest pressure is applied to the sciatic nodules (both hip bones) at the buttocks. If the elasticity of the upper surface of the seat plate is constant, it will cause excessive strain on the left nodule when sitting for a long time, causing discomfort in the lumbar vertebrae and spine, and it will be difficult to maintain the correct posture during sitting for a long time. This distraction and skewed posture for a long time not only causes spinal diseases in the growing stage, such as the spine bending. When high pressure is applied to the sciatic nodules for a long time, blood circulation of the buttocks is not smooth, leading to anal diseases, muscle diseases, and urinary diseases.

In order to solve the above problems, the present invention forms a groove in a part of the seat where the buttocks are located when seated on a chair or a seat and couples the various elastic cushion members in the groove of the seat to apply pressure to the sciatic node of the buttocks. It is an object of the present invention to provide a chair and a pedestal for dispersing a portion of the buttocks to other portions of the buttocks, thereby maintaining a smooth circulation of the buttocks while maintaining a correct posture during prolonged sitting.

In order to achieve this object, according to the present invention,

When the seated person sits on the seat plate, an elastic portion having an elastic force is formed in an area of the seat plate corresponding to a portion pressed by the seat occupant's hip, wherein the first elastic portion pressed by the user's sciatic node is one of the other elasticities. Since the elastic force is weaker than that of the part, the seat plate is provided so that the pressure applied to the first elastic part by the sciatic nodule of the seated person can be dispersed toward the second elastic part.

In addition, according to the present invention, a groove is formed in a region corresponding to the elastic portion of the seat plate, a first elastic body having a first elastic force is filled in a region corresponding to the first elastic portion of the groove, A seat plate is provided in which a second elastic body having a greater elasticity than the first elastic force is filled in a region corresponding to the second elastic portion.

In addition, according to the present invention, there is provided a seat plate characterized in that the pad is laid on the bottom of the groove.

In addition, according to the present invention,

The seat plate, characterized in that the pad is made of a material for pharmacological action.

In addition, according to the present invention, a chair is provided comprising a seat plate as defined above.

In more detail, this configuration forms a groove in a part of the seat where the sciatic nodules are placed when seated on a chair or seat, and wraps the cushion with a layer of elastic material for dispersing the pressure applied to the sciatic nodules. The member is manufactured and inserted into the groove of the seat plate, and the pad is formed for the health at the bottom of the cushion member and selectively inserted.

The cushion member is made of several layers of elastic bodies with different elasticities. The edge of the cushion member is made of strong elasticity, the inner elasticity is weak and soft, and the whole elastic body is wrapped in a thin outer shell, and the outer shell is thin so that the effect of the elastic body inside is thin. It is felt from the outside and is made of material which is strong in abrasion durability. Pads for health supplements can be used selectively, pads are made of charcoal, ocher, bioceramic, etc., wrapped in a vegetation material having an antibacterial, deodorant, moisturizing effect and then placed in the bottom groove of the cushion member, antibacterial, In some cases, a pad made by foaming to a desired shape by adding a flora and fauna having deodorizing and moisturizing effects to a foaming material such as polyurethane or polyester may be used.

(Example)

Hereinafter, preferred embodiments of the seat plate and the chair according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a first embodiment of the present invention, the seat plate 12 is mounted with a cushion member 20 according to the present invention, the support 13 supporting the seat plate, and the backrest 11 of the chair Perspective view. The back 11 of the chair may be flat or curved, or may not be present. The support of the chair may be one, two or more, or may be used as the seat plate itself without the support. The top view of the grooves in the seat can be shaped in various shapes such as square, circle, ellipse and semicircle. The groove upper area is preferably manufactured from 50 cm 2 to 600 cm 2 with the buttocks placed at the center. The location of the grooved center is preferably within the range of 7 cm to 15 cm at the rear end of the chair, but can be changed to the position where the buttocks are placed depending on the depth of the chair.

2 is a partial longitudinal cross-sectional view of a chair according to a first embodiment of the present invention, when seated on a chair or a seat, a seat plate 12 having a groove in a portion where the buttocks are placed and a cushion member 20 inserted into a groove of the seat plate; The internal cross section of is made of detail. In the middle of the cushion member, there is a first elastic body 23 having a weak elasticity, and a second elastic body 22 having a strong elasticity surrounding the cushion member, and the outer shell 21 surrounding the elastic bodies.

When sitting in a chair according to the first embodiment of the present invention, the first elastic body 23 that is weak in elasticity at the sciatic nodules, which is under the most pressure, is pressed a lot, and the second elastic body 22 is pressed slightly due to its strong elasticity. The cushion member that receives the least amount of pressure is not pressed. When seated, the area surrounding the sciatic nodules is increased as the first elastic body 23 is pressed most, and the pressure at the sciatic nodules is considerably reduced by transferring pressure to the second elastic body 22 which is less pressed. In addition, since the first elastic body 22 is slightly pressed but the circumference thereof is not pressed, the pressure received by the second elastic body is also slightly transmitted around. Therefore, by sitting at the edge of the buttocks where the pressure of the sciatic nodules, which is the most applied from the upper body to the buttocks at the time of sitting, the entire buttocks are evenly pressured, making the seat feel smooth and not exhausting even after sitting for a long time. It does not change, and maintains the blood circulation of the sciatic nodule smoothly to maintain health. In order to make the seat plate feel softer, it is also possible to insert the third and fourth elastic bodies between the first and second elastic bodies 23 and 22 in the cushion member 20.

3 is a second embodiment of the present invention, the seat plate 12 is mounted on the lower end of the cushion member 20 of the first embodiment of the pad 24 to support the health and the support 13, the back plate 11 supporting the seat plate 11 It is a chair made of). It is preferable that the compressive strength of the pad 12 is greater than the compressive strength of the cushion member 20, and the material inserted into the pad 24 may be formed by compressing a vegetable material such as charcoal or wormwood. It can be made of clay, jade, etc. Since the pharmacological action of the substance contained in the pad through the breathable cushion member to the seated person can protect the health of the seated person working for a long time sitting. By adding additives with far-infrared or therapeutic effects to the pads, moisturizing, moisture-proofing, deodorizing, and warming effects can be expected, especially anal diseases and urinary diseases.

4 is an embodiment of a chair made of a seat plate 12, a support 13, and a backrest on which a cushion member 30 made of a single elastic body is mounted as a cushion member.

Although not shown in the figure, the portion pressed by the sciatic nodule of the cushion member 30 has a lower elastic force than other regions, and thus, as in the first and second embodiments, the pressure generated by the sciatic nodule is Disperse to other areas.

Since the basic concept of the present invention is in the structure of the seat plate which can disperse the pressure applied to the part pressed by the seat plate sciatic nodules to other parts, the present invention is not limited to the above specific embodiments, for example It is also possible to form the seat plate integrally so that the portion pressed by the left fracture of the seat plate is relatively less elastic than other portions, without forming a groove in the seat plate, and any form of chair or sofa including such a seat plate It can be applied to all seating means.

As described above, the present invention is made by moving the pressure of the sciatic nodule, which is the most applied from the upper body to the buttocks at the time of sitting, to the edge of the buttocks where the pressure is less. Soft, sitting for a long time does not exhaust, does not change the posture, and maintains the blood circulation of the sciatic nodules smoothly to maintain health. In addition, by attaching to the health pad can be expected to moisturize, moisture-proof, deodorant, heat effects, especially anal diseases or urinary diseases are helpful.
