Description

The present invention relates to chairs.

There are chairs with cushions on the seat surface to prevent pain even when sitting for a long time.

JP 2013-90886

If you sit in a chair for a long time, the weight of your upper body will continue to be received by the part of your buttocks below the femur, so the surrounding area will not receive the weight, and the weight of your upper body will be received by a small area. In order to prevent pain, cushions are provided on the seat surface, but the pain does not move, so the pain returns over time.

Since the seat bears the weight of the upper body, cushions lose their elasticity over time, and since the frame and seat are made in one piece, if the surface of the seat is damaged, you will have to buy a new chair. , not economical.

Due to the above problems, it is an issue to provide an economical chair that is gentle on the buttocks and does not cause pain even after sitting for a long time.

Two armrests protruding from two rear legs are placed in both cylinders of the suspended seat surface, and the suspended seat surface is suspended from the left and right armrests so that the user can sit on the seat surface.

The cylinder and the seat are made of cloth.

At the center of the seat, a half frusto-conical air bladder was attached, with the front semicircle becoming progressively smaller as it went into the seat.

I double stitched both ends of the seat fabric where there is no cylinder.

I sewed the end of the cylinder and the seat surface together.

Cylindrical stoppers were provided on both ends of the armrest that was put into the cylinder.

The tip of the armrest is hemispherical.

The frame of the chair is shaped to prevent it from tipping over.

Reinforcing plates are provided at the corners of the armrests and rear legs.

When you sit on a chair with a hanging seat, your hips are wrapped in a soft cloth that conforms to the shape of your buttocks, instead of resting on a hard object or a cushion placed on top of a hard object, so you can sit in a relaxed state.

When you sit down on the suspended seat, the fabric that touches your hips and thighs, which receive the weight of your upper body, is large, so the burden on each part is reduced, and your buttocks will not hurt even if you sit for a long time.

You can sway your buttocks on the seat from side to side, the area on the seat is large, and there is no pressure on the seat, so you can sit for a long time without having poor blood circulation.

There is no seat frame to support the seat surface, and the thickness of the seat surface made of cloth is thin, so you can put your shins under the seat while sitting, so you can place your feet under the seat and use your legs to weight your body. If you receive it, you won't have to lean your upper body against the hard backrest if you rest your upper body on the soft seat, and you can work in a healthy posture with your back straight.

To insert the armrest into the cylinder, it can be easily inserted by pressing the hole in the cylinder against the hemisphere at the tip of the armrest.

Since the cylinder can be easily removed from the armrest, the hanging seat surface can be washed, and when scratches or stains cannot be removed, the hanging seat surface can be removed and replaced with a new one, so it is hard to break. You can use the frame for a long time, and you can also use a hanging seat with a different design for each season.

A semi-truncated cone-shaped air bag is attached to the center of the seat surface, so the weight of the inner thighs is also transferred to the seat surface, so the reaction force that the buttocks and thighs receive from the seat surface is slight, but it is dispersed and small. and become easier to sit on.

By adjusting the air inside the bag with the stopper of the semi-truncated cone, the air volume in the bag can be adjusted to the optimum level, which makes sitting more comfortable.

Both ends of the seat cloth are sewn together, so there are no gaps on both ends of the cloth.

The end of the cylinder and the cloth of the seat surface are joined with a wide width, so the cylinder can withstand heavy weight.

Since the position of the armrest is not so far from the human body, the slope formed by the suspended seat surface descending from the armrest and the human thigh and buttocks is steep, so the area that touches the thighs and buttocks is widened, and the body is placed on the seat surface. weight is easily distributed.

There are cylinder stoppers on both ends where the cylinder of the armrest is fitted, so the cylinder does not slip easily.

Since the tip of the armrest is hemispherical, the armrest can be easily inserted into the cylinder.

Since the seat surface is made of cloth, it can be made into a suspended seat surface made of cloth for people with light weight or heavy weight.

Reinforcing plates are provided at the corners of the armrests and rear legs, so you can grasp the armrests to raise your upper body from the seat, and when you sit down on an irregularly shaped seat, you can hold the armrests and slowly lower your back. You can also put it down.
