Problems solved by technology

[0008] However, the above existing designs are difficult to make the lumbar support close to the lumbar spine when a person sits down, and there are problems of insufficient support effect and inconvenient adjustment means.
[0009] In addition, in the prior art, there is generally a lack of consideration for how to support the head and cervical spine in the working state, and the protection design for the elbow and arm is not perfect

Embodiment approach 1

[0071] The cushion mechanism is mainly composed of a fixed base plate, a movable cushion and a lumbar cushion, and the movable cushion is composed of a cushion base plate and a cushion. The rear ends of the two base plates are equipped with hinges 3, and stage clips 4 are arranged between the two base plates. Figure 2a , which is the free state of the computer chair before the person sits on it; when the person sits on the computer chair, the spring 4 at the bottom of the movable bottom plate 2 is compressed. Due to the effect of the L-shaped support 6 installed on the hinge 3, the lumbar pad 5 is driven to lean forward, against the waist. See Figure 2b .

Embodiment approach 2

[0073] Figure 2c with Figure 2d It is another design of the cushion mechanism. In order to increase the strength of the lumbar support for the lumbar cushion, the fulcrum of the hinge 3 is properly moved forward from the end, and the hinge 3 can be set at a place whose distance from the rear end of the movable cushion is greater than 0 and less than 1 / 3 of the length of the movable cushion, forming a seesaw structure. See Figure 2c . When a person sits on the seat, the seat cushion bottom plate 2 is pressed down, driving the lumbar cushion 5 rotating around the fulcrum hinge 3 to push forward against the person's waist; Load onto rotating shaft on the L-shaped support 6, be covered with torsion spring 7 on the rotating shaft. By selecting the appropriate torsion spring stiffness and number, the waist pad 5 can be pressed against the waist of the person with appropriate force. The reaction force of the waist to the lumbar pad 5 makes the lumbar pad 5 always resist the w...

Abstract

The invention relates to a computer chair beneficial to the health of a human body. The computer chair beneficial to the health of the human body is characterized in that a cushion mechanism of the chair mainly comprises a fixed bottom plate, a cushion bottom plate and a bolster, wherein the bolster is adhered to the cushion bottom plate; a compression spring located at the front end of the fixed bottom plate is used for connecting the fixed bottom plate with the cushion bottom plate above; a lumbar pad is arranged between a backrest bracket and a movable cushion, and is connected with the cushion bottom plate through an L-shaped bracket; a hinge is located at the back ends of the fixed bottom plate and the movable cushion and is used for connecting the fixed bottom plate with the cushion bottom plate; or a rotating shaft is arranged at a turning place of the L-shaped bracket; torsion springs are mounted on the rotating shaft in a sleeving manner; a hinge is arranged at a place which has a distance of more than 0 to the back end of the movable cushion but less than 1 / 3 of the length of the movable cushion, and is used for connecting the cushion bottom plate with the fixed bottom plate. According to the computer chair beneficial to the health of the human body, a headrest, armrests and leg pads are subjected to improved designs at the same time, so that the fatigue during working can be relieved through the computer chair, and the health of the human body is facilitated.

Description

technical field [0001] The invention relates to a computer chair, which is especially suitable for people who work in front of a computer for a long time, and belongs to the manufacture of office furniture. Background technique [0002] With the progress of the times, the use of computers has become more popular, and the work of all walks of life is inseparable from computers. Whether it is a programming engineer, designer, network manager, company secretary, or bank staff, technology design and development personnel, it is inevitable to work long hours in front of the computer. Accompanied by the completion of the work, there are various diseases of the cervical spine, spine, shoulders, coccyx, lumbar intervertebral disc herniation and so on. [0003] According to statistics, the ratio of a series of strains and pains caused by lumbar intervertebral disc herniation, cervical spine, shoulders, spine, and tailbone due to improper sitting posture and seat design is as high as...
