(57) [Summary] [Problem] To be in a stable chair that is comfortable for back pain where the waist and back are not tired even when sitting for a long time. SOLUTION: An elliptical deep dish shape with an open bottom is molded from plastics or the like, and fitted to a chair stool with the knees lowered, widely supported around the buttocks, and the ischial bone is formed at the bottom opening. I tried not to hit. The backrest is supported by the back to reduce the strain on the waist.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure in which a back and a waist of a sitting chair and a seating chair are not tired.

[0002]

[Prior art]

 The chair stool is flat with a spring or the like as a cushion. Some have a concave backrest that curves inward as shown, while others lean back and lean back.

[0003]

[Problems to be solved by the invention]

 If the plate that supports the waist is flat, the upper body is supported by the ischial bones, which directly hits the waist and back, causing a burden. If a spring is used as a cushion and the spring is crushed, the knee will bend upward and bend. Because the backrest is separated from the stool, the back cannot be supported.

[0004]

[Means for Solving the Problems]

 The flat was supported around the buttocks, and the mold was constructed so that the ischia did not hit it. The knees were lowered and fitted to the stool. The backrest also plays a role in supporting the upper body with the back, so that the backrest is positioned so that it does not separate from the body.

[0005]

[Embodiment of the invention]

 When sitting on an oval deep dish with an open bottom, the buttocks are supported by the edges and sides of the deep dish, and the hips and back are not cracked because the ischial does not hit. The backrest also rests on the stool and curves outwardly, supporting the back and reducing the strain on the lower back.

[0006]

【Example】

 This will be described with reference to the accompanying drawings. Reference numeral 1 denotes a hip support, which is formed by molding an elliptical deep dish using a material such as plastics. Each part of the buttocks is widely dispersed and supported in 1, 1a and 1b. Reference numeral 2 denotes a bottom opening, which floats without hitting the ischial bone. Reference numeral 3 denotes a backrest, which is a curved surface that is curved outward and is located on the stool and supports the back.

[0007]

[Effect of the invention]

 As we support around hips widely, we are stable and do not get tired. Because it does not suppress the ischium, it can withstand the waist and back without cracking. Since the knee does not rise, it does not bend. You can rest your back. Also applies to chairs.
