Embodiment 1

[0056] Embodiment 1: as Figure 1 to Figure 4 , Figure 19 to Figure 22 , a seat structure capable of sharing body weight by the waist, including a seat surface 1 that can be lifted up and down and a lumbar support assembly 2 that is opened or clamped, and the lumbar support assembly includes a pair of brackets 21, a driving member 22 and a link mechanism 23, wherein the brackets 21 are located on both sides of the chair surface, the tops of the two brackets are connected to the seat, and the outside of the brackets 21 is clamped to the center by the matching driving member 22 and the linkage mechanism 23 To achieve the purpose of tightening the waist. The driving parts are two groups, which are respectively located on the outside of the two brackets. Each group of driving parts includes a crank 221. One end of the crank has a roller 222 and is pressed against the bottom of the outer side of the bracket. The middle of the crank is connected to the chair surface through a conn...

Embodiment 2

[0058] Example 2: see Figure 7 to Figure 13 , a seat structure that can share the weight of the body with the waist, including a seat surface 1 that can be lifted up and down and a lumbar support assembly 2 that can be opened or clamped. There is a double-layer structure under the seat surface, one of which is filled with liquid Bag or liquid water bag 42, this liquid bag or liquid bag are communicated with the protective bag or the protective bag 210 inboard of both sides support tool by pipeline, regulating valve is installed on the pipeline to control the liquid in the liquid bag or liquid bag under the chair surface The weight of the human body is transferred to the protective bag or protective bag inside the supporting tool to improve the comfort of supporting the waist of the supporting tool. Another layer of spring elements is installed under the seat surface, such as spring 41, which can be used for energy storage and driving to reset. The present invention mentions t...

Embodiment 3

[0060] Embodiment 3: as Figures 16 to 18 As shown, the lumbar support assembly 2 is divided into two groups, which respectively extend downwards to the seat surface 1 to form a lumbar support part 21 and a connecting rod part 22. The lumbar support part is inwardly convex to support the waist of the human body. The middle part is hinged on the chair frame, and when the chair surface moves down, pressure is applied to one end of the connecting rod so as to drive the two lumbar support parts to squeeze inward to tighten the waist.

Abstract

The invention discloses a chair structure capable of assisting waist to share the body weight, which comprises a chair seat, the chair seat has a chair surface capable of elevating up and down, a waist holder component capable of opening and clamping, when people sets on the chair surface, the potential energy which moves downwards is conversed to driving force which is clamped by the waist holder component, so that the waist holder component can tightly support the waist for sharing the body weight of the body. The chair possesses the chair structure which can depend on the self weight of human body to drive a waist holder part for sharing the body weight. The waist holder component of the present invention can tightly support on latissimus dorsi and abdominal external oblique muscle, thereby the bearing degree of lumbar vertebra when people is sat on the chair can be reduced, and the chair structure has the advantages of reasonable structure, safety and health care.

Description

technical field [0001] The invention discloses a seat structure capable of sharing the weight of the body by the waist, which belongs to the technical field of seats according to the International Patent Classification (IPC), and in particular relates to a seat capable of carrying the weight of the body by the waist to achieve the function of health care structure. Background technique [0002] Traditional seats generally have a seat for the human body to sit on. When the human body sits on the seat surface, the body weight is supported by the seat. From the physiological structure of the human body, the spine of the human body carries the upper body of the human body such as the head and back. Since the lumbar spine is at the lowest position of the spine, the load is quite heavy, and it is also the junction of the movable segment and the fixed segment, so it is more vulnerable to injury. If the sitting posture of the human body is not correct, in addition to looking sluggi...
