The seat chair of the present invention can be suitably provided with a detachable shock absorber.

  According to the present invention, the center of the seat can be raised by providing a connecting bracket that bends the front part of the seat downward in a substantially central part of the seat, so that the foot is in a natural state while seated. It becomes possible to bend and use, and the burden on the knees and toes is reduced, and the relaxed feeling and stability are improved. In addition, by providing a connecting bracket that bends the head placement portion inwardly at the top of the backrest, the head mounting angle can be adjusted freely, reducing the burden on the neck and shoulders. it can. Furthermore, by providing a detachable shock absorber on the seat chair, the cushioning properties of the head and waist when sitting can be enhanced.

Hereinafter, embodiments of a seat chair in the present invention will be described based on the drawings.
FIG. 1 is an overall perspective view of a seat chair 1 which is a preferred example of the present invention, and FIG. 2 shows the internal structure of the seat chair 1. The seat 1 includes a connecting bracket 4 that connects the seat 2 and the backrest 3 and connects the seat 2 and the backrest 3 so that the angle of the seat 2 can be adjusted. Further, the seat portion 2 and the backrest 3 are each formed by a shaped pipe core material 5. Further, a cushioning material 6 made of urethane foam is disposed on the seat portion 2 and the backrest 3, and a cover 7 is covered around the cushioning material 6.

  The cover 7 is preferably formed of, for example, a highly breathable mesh fabric, and the head placement portion 3a at the top of the backrest is, for example, a white mesh fabric, the backrest 3 and the seat 2 are For example, a red or black mesh fabric is preferably used. Thereby, a novel and highly fashionable texture can be brought out from the whole seat 1.

  A connecting metal fitting 8 that bends the seat front portion 2a downward is attached to a substantially central portion of the seat 2. The connecting fitting 8 can be a general-purpose ratchet fitting that is mounted on a general-purpose seat chair and adjusts the angle of the seat and backrest in multiple stages. By mounting the connecting metal fitting 8, the seat 2 can be formed in a mountain shape, and as shown in FIG. 4 (b), it is possible to bend the foot in a natural state while sitting, and to feel relaxed. And stability is improved.

  Further, on the upper part of the backrest 3, a connection fitting 9 for bending the head arrangement portion 3a in the inner direction is mounted. The connecting fitting 9 is mounted on the upper part of the backrest 3 at a position where a neck and a shoulder are disposed when a seat chair is used. By attaching the connector 9, as shown in FIG. 4A, the head placement portion 3a can be freely raised and lowered, and the head mounting angle can be arbitrarily adjusted.

  Moreover, as another suitable example of this invention, the cushioning tool 10 which can be attached or detached to the seat 1 can be comprised suitably. As shown in FIG. 3, the shock absorber 10 has a bowl-shaped main body 11 formed of a shock absorbing material 12 housed therein, a cover 13 covered around the shock absorbing material 12, and both sides of the main body 11. It is comprised with the elastic material 14 with which the surface was mounted | worn. The cover 13 is preferably made of a highly breathable mesh fabric.

  When the shock absorber 10 is mounted on the seat chair 1, the shock absorber 10 can be disposed at a desired location by extending the stretchable material 14 and inserting it from the backrest 3 or the end of the seat portion 2. By disposing the shock absorber 10 on the backrest 3 or the seat 2, a high cushioning property during use can be obtained. For example, as shown in FIG. 4 (a), the head arrangement part 3a is erected, and the cushioning tool 10 is arranged on the upper surface of the head arrangement part 3a, so that the back head, neck, and shoulder cushions are provided. This makes it easier to read and listen to TV in a lying position. Further, as shown in FIG. 4 (b), the backrest 3 is erected, and the cushioning device 10 is mounted in the vicinity of the waist arrangement of the backrest 3, so that cushioning is obtained and the waist is stretched. Thus, a comfortable seating state can be maintained even when used for a long time.

It is a whole perspective view of a partially cutout state of a seat chair in the present invention. It is a general view which shows the internal structure of the said seat. (A) is a perspective view showing the surface of a buffer, (b) is a back view showing a back surface, respectively. (A) is the explanatory view showing the example of use of the state where the buffer was arranged in the head arrangement part, and (b) the state where the buffer was arranged in the waist.
