Abstract

An object of the present invention is to provide a seat-chair spacer which disperses weight to a thigh and a back, prevents hip displacement, prevents pressure on a lumbar spine, prevents back pain, and improves sitting comfort. An approximately trapezoidal seating spacer having a raised front is inserted between a frame of a seat of a rotating seat and a cushion. The front side of the spacer is regulated by the outer frame, and the weight of the ischial tuberosity is distributed to the thighs and the back to prevent hip displacement, prevent lower back pain, and improve sitting comfort.

Description

In order to improve the sitting comfort of a swivel chair with a horizontal seat frame and an outer frame on the seat frame, the present invention is used for a seat chair used between a seat frame and a cushion. It relates to assistive devices.

With various living cultures in widespread use, many Japanese-style and Western-style chairs are used, and swivel chairs are easy to use, inexpensive, and attractive, so I often see them. In many cases, a rotating disk is attached between the base frame and the bottom frame of the seat, so the bottom of the seat is horizontal and the seat is also horizontal.

This is because the bottom frame of the seat is horizontal, so that the hips are pushed forward by the load on the back, and much of the weight is concentrated only on the sciatic nodule, and the buttocks are shifted forward. In some cases, it was thought that the lumbar spine was compressed and this caused back pain.

As a countermeasure, I sometimes sit back or stand up and stretch my back to continue working, but often my concentration was lost and eventually my back became painful.

The problem to be solved is to disperse the weight of the sciatic nodule in the thigh and back to prevent hip dislocation, prevent pressure on the lumbar spine, prevent back pain and improve sitting comfort.

Concentrated load on the sciatic nodule by inserting the seat spacer of the present invention between the bottom frame of the seat and the cushion on the swivel chair where the bottom frame of the seat is flat and the outer frame is mounted on it. Is distributed over the thigh and back, and the main feature is a substantially trapezoidal shape with the front side raised.

By placing the substantially trapezoidal spacer of this plan on the back side of the outer frame on the horizontal seat base frame, the spacer is regulated on the front side by the outer frame, and the weight to the sciatic nodule is on the thigh and back Disperse to prevent buttocks, prevent back pain and improve sitting comfort.

It is a perspective view of a swivel chair and a seat chair spacer of the present plan. It is the perspective view which built the seat chair spacer of this proposal in the rotation seat. It is the top view of FIG. 2, and the side view of a center cross section. It is a perspective view of the present rotating seat chair. FIG. 5 is a perspective view showing a first embodiment of the seat spacer. FIG. 6 is a perspective view showing a second embodiment of the seat spacer, and the lower figure is a perspective view from the back. FIG. 7 is a perspective view and a sectional view showing a third embodiment of the seat spacer. FIG. 8 is a perspective view and a sectional view showing a fourth embodiment of the seat spacer.

The purpose of spreading the weight of the sciatic nodule to the thigh and back to prevent hip slip and to prevent back pain, and to improve the sitting comfort. The problem was solved simply by placing it between the seat bottom frame of the seat and the cushion.

FIG. 5 shows the first embodiment, in which a thin upper frame 1f and a lower frame 1h are attached with screws 1i to a plurality of side frames 1g along the outer shape of a substantially trapezoidal main body whose front is high. Are making.

FIG. 6 shows a second embodiment, which is manufactured by integrally molding a substantially trapezoidal upper portion, side surfaces, and reinforcing ribs 1m with a front portion higher with resin and metal.

FIG. 7 shows a third embodiment, which is manufactured by press-molding a substantially trapezoidal outer periphery whose front is high with a thin plate of metal and resin.

FIG. 8 shows a fourth embodiment, which is manufactured by integrally molding a substantially trapezoidal shape having a high front side with foamed resin such as foamed polystyrene and urethane.

The present invention can be used not only with legs extended, but also with crossed legs and kneeling, and is expected to be widely used for long-term personal computer work, desk work, television and audio viewing.
