Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to a chair, and more particularly, to a chair that can maintain the correct posture of a person sitting on the chair. Regarding chairs.

People who want to sit with proper posture should arch the lower part of the spine slightly and lower the other parts of the spine. The minutes need to be relatively straight. And can correct posture prevent back pain? A chair that is known as an example of something that keeps the person sitting in the correct posture A chair with an inclined seat.

This chair can straighten the spine of the person sitting on it. Inclined seat aid As a member, knee restraints are used to prevent the person sitting on the seat from falling. e rest) may also be provided.

The disadvantage of this traditional seat is that the pressure exerted on the knees can cause discomfort over time. It is about giving.

It is an object of the present invention to provide a chair member which substantially overcomes or improves the above-mentioned disadvantages. That's true.

Disclosure of invention The chair member according to the present invention is composed of a seat and a backrest or a cushion. The chair member includes a front support portion made of a relatively dense elastic body and a front support portion made of a relatively dense elastic body. It has a rear support part made of a relatively low-density elastic body adjacent to the front support part. Ru. Therefore, depending on the weight of the person sitting on the chair, the distance between the front support part and the rear support part may vary. There is a difference in the amount of deformation between the crabs, which causes the rear part to deform slightly more than the front part. and When the roller is in use, the rear part is higher than the front part.

The present invention also provides a chair using the above-mentioned chair member, i.e., the chair member is tilted. Alternatively, the seat can tilt, and the difference in the amount of deformation causes the ischial tuberosity of the seated person to move forward with the front support. Positioned behind the holding part, this also prevents the seated person from sliding forward. Provide chairs.

The chair member is used as a tilted or tiltable seat of the chair. preferable. However, such components may be used for portable or removable seats, cushions, etc. Or it can be used as a backrest. It is also a traditional chair horizontal It can also be used as a seat.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Please note that this implementation Examples are illustrative only.

Brief description of the drawing FIG. 1 shows a chair of the invention in which a skeletal person is shown sitting in the correct posture. It is a side sectional view of a child.

2 is an enlarged cross-sectional perspective view of the seat shown in FIG. 1; FIG.

FIG. 3 is a cross-sectional perspective view of the cushion according to the present invention.

FIG. 4 is a cross-sectional perspective view of a chair using the backrest of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1; a chair 1 according to an embodiment of the invention is provided with a tilting It consists of slanted seats. Backrest as needed to provide additional support 4 may be provided. The chair 1 has a seat 2 and a backrest 4 that have the required height and height in the conventional manner. and tilt:aS.

As shown in Figures 1 and 2, the tilted seat is made of relatively dense elastic material. It has a base 5 to which a front support 6 made of plastic material is attached. are doing. The base has a relatively low density and is arranged adjacent to the front support 6. It also supports a rear support 7 made of an elastic plastic material. Book In the embodiment, both supports are covered separately by suitable covers 8.

The cover 8 may be made of one piece, in which case the cover is divided by the horizontal bar 10 and the base Preferably, it is fixed to the upper surface of 5.

As shown in FIG. 1, when a person 11 sits on the chair member 2, the difference in the density of the supporting parts As a result, the rear support part 7 deforms slightly more than the front part 6. do. This causes the seated person's ischial tuberosity to be located at the rear of the front support 6, usually at the front. The gap between the support part and the rear support part]3 will be reached. Front support part 6 This will cause it to hit the ischial tuberosity, and the person sitting on the seat should be careful not to slip and fall. It is well protected.

FIG. 3 shows a second embodiment of the invention in the form of a cushion 14. So The cushion may be portable or may be used on a conventional bench or seat (not shown). The difference is that it is sloped so that it is higher on the top. Similarly, the front support part 6 It is slanted and in this example also forms the base of the cushion. rear support The holding part 7 extends forward and covers the front support part 6, forming a relatively soft and thin front cover. is formed.

The function of the cushion 14 is similar to that of the chair 1. The cushion 14 is shown in Figure 1. and may be constructed in a manner similar to that shown in FIG. However, in that case the upper surface needs to be sloped appropriately.

In another embodiment of the invention shown in FIG. 4, the chair member 17 forms a back rest. are doing. In this embodiment, the front support part 6 with high density is placed on the shoulders of the seated person. The rear support part 7, which has a small deformation density, is arranged at the bottom of the backrest so that it can be deformed more. Ru. As a result, the sitter's back is better supported and relatively straight . The backrest 17 can be used as part of a conventional chair or as a seat 2 or a It can also be used in combination with a seat manufactured in the same manner as Section 14.

Although the present invention has been described above with reference to specific examples, those skilled in the art will understand that the present invention It will be appreciated that other examples may also be implemented.
