Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , The chair disclosed in this embodiment is mainly composed of three parts: a cushion portion 11 , a leaning portion 12 and a support portion 13 , wherein the cushion portion 11 and the leaning portion 12 are connected by a shaft 14 . Both the cushion part 11 and the leaning part 12 are composed of inner and outer parts. The outer layer is a coat made of a material with good stretchability and air permeability. The volume of the coat depends on the total volume of the inner filler, and the shape of the coat is cut according to the ergonomic curve. The inner filling is composed of an air-filled hollow ball.

[0018] Such as figure 2 , according to the principle of mechanics, if the spherical object A0 is subjected to a downward pressure N, then this force can be decomposed into two orthogonal forces N1 and N2, and th...

Abstract

The invention relates to a chair. The chair comprises a support part, a pad part and a leaning part, wherein the pad part and the leaning part are both filled with spherical objects, each spherical object is hollow and filled with air; the exteriors of the pad part and the leaning part are both made of elastic material; the pad part and the leaning part are connected by a shaft, and the angle between the leaning part and the pad part can be adjusted through the shaft; the contact surface of the support part and the pad part is a curved surface, and the pad part can shake on the support part; and the height of the support part is adjustable. The exterior of the chair is made of elastic breathable material and contains a plurality of spherical objects; when people sits on the chair, the positions of all the spherical objects are changed so as to ensure that the chair curve can be automatically adjusted according to body curvature, the effect of dispersing pressure of each part of a human body can be achieved, and symptom of local numbness of a body caused by long time sitting can be prevented; air is inflated in the spherical objects, the pad part and the leaning part can recover automatically after deforming on the basis of the principle of thermal expansion and contraction; therefore the chair does not deform even if used for a long term.

Description

technical field [0001] The present invention relates to a chair. Background technique [0002] Chairs are essential in our daily life. Existing seat has following several: (1) hard seat, usually is made of wood, and its seat board and backrest are all hard usually, and the time of sitting for a long time can have local numbness. (2) For chairs with cushions, sponge pads are added to the chair cushions and backrests. The contact surface is relatively soft, but the cushions will be sunken after sitting for a long time, and the ventilation and heat dissipation performance is not good. After long-term use, the cushions will be seriously deformed. (3) Health care chairs, which usually use electronic control systems and are designed for specific health care items, are expensive and cannot be popularized; in addition, electronic systems will have different degrees of radiation when they work, and long-term use will also cause harm to users. adverse effects.
