Embodiment Construction

[0022] The chair that the present invention proposes changes with the sitting posture of the human body, and its structure is as follows: figure 1 As shown, including seat A and bracket B. After the seat surfaces A are folded together, an upper seat surface 1 and a lower seat surface 5 are formed, such as figure 2 shown. Bracket B is processed into leg support bar, seat surface support bar and back support bar from a pipe. The upper seat surface 1 is relatively fixed with the back support bar, and the lower seat surface 5 is relatively fixed with the seat support bar.

[0023] In the above-mentioned chair of the present invention, the planar development of the chair surface is as follows: figure 2 As shown, the right side of the seat surface has a right longitudinal first folding line 3 and a right longitudinal second folding line 4, and the left side has a left longitudinal first folding line 8 and a left longitudinal second folding line 7, and the middle of the seat sur...

Abstract

The invention relates to a chair capable of changing with the setting posture of human body, belonging to the technical field of human living necessity. The chair comprises chair surfaces and a support, wherein the chair surfaces are folded together to form an upper chair surface and a lower chair surface; and the support comprises a leg-part supporting bar, a chair surface supporting bar and a back supporting bar which are prepared from a tube. The upper chair surface is fixed relatively to the back supporting bar, and the lower chair surface is fixed relatively to the chair surface supporting bar. The chair surface of the chair capable of changing with the setting posture of human body is folded to ensure that the chair can vary with the setting posture of human body and ensure that people can feel comfortable. Different sizes of chairs can be produced according to the human engineering data, thus ensuring that the chair can adapt to different somatotypes of people and the chair is suitable and comfortable. The chair of the invention has simple production technology and convenient packaging and assembly and can be widely applied in meetings, offices, households, etc.

Description

technical field [0001] The invention relates to a chair which changes according to the sitting posture of a human body, and belongs to the technical field of necessities for human life. Background technique [0002] A traditional chair is generally composed of three parts: a sitting surface, a backrest and a support frame, and the backrest and the sitting surface are rigid. Due to the rigidity, the size of most chairs can only be designed according to the 5-95th percentile of ergonomics. Although it can meet the needs of most people's seating, it cannot make people feel comfortable when sitting. In addition, people often need to adjust their sitting posture when sitting on a chair, and move back and forth or left and right to relieve the fatigue caused by one posture for a long time. However, the rigid backrest and sitting surface cannot be deformed with the sitting posture of the person. Therefore, some seats used in banks, offices, etc. need to design complex adjustment ...
