Embodiment Construction

[0020] The invention includes a bottom frame, a lumbar support, a back support, a seat cushion, a lumbar cushion and a back cushion.

[0021] The underframe includes steel pipes (G), steel pipes (P) and two sets of steel frames welded by steel pipes (H, I, J, R). The end of steel pipe (G) has threaded hole, passes through the through hole of steel pipe (I) by screw to connect it. The steel pipe (P) and the steel pipe (R) are nested and connected by two kinds of steel pipes with different diameters. There are several positioning holes on the steel pipe with a large diameter, and there are several positioning holes on the steel pipe with a small diameter. The two steel pipes can slide relative to each other. Several positioning holes are respectively arranged on the steel pipe, and positioning pins are worn in the positioning holes, which play the role of adjusting the gear position.

[0022] The lumbar support includes steel pipes (A), steel pipes (N) and steel pipes (O). A p...

Abstract

The invention relates to an experiment seat with a seat surface and a seat back, which can support human bodies synchronously in variable sitting postures and a regulating method. The experiment seat comprises a bottom support, a waist part support, a back part support, a seat cushion, a waist cushion and a back cushion, and according to the corresponding regulating method, the seat is suitable for different users and different working conditions. The experiment seat is characterized in that the seat cushion can be regulated in height, depth and an horizontal rotating angle; the waist cushion can be regulated in height, depth and the horizontal (X axis) rotating angle; the back cushion can be regulated in height, depth, the horizontal (X axis) rotating angle and a vertical (Z axis) rotating angle; the height of the waist rotary shaft point of the waist part support, connected with the bottom support, is greater than the height of the seat surface; a connecting line of rotary shaft points at two sides of the waist part is positioned on the middle rear end of the seat surface; and the waist part rotary shaft points can be regulated in the height and depth directions. The experiment seat has the following application value of providing a seat resolution scheme which can enable people to be supported reasonably in forms of a forerake sitting posture, a vertical sitting posture and a hypsokinesis sitting posture.

Description

[0001] The invention relates to an experimental chair and an adjustment method. The seat surface and the chair back of the experimental chair can support the human body synchronously when the sitting posture is changed. The adjustment method can make the seat suitable for different users and different people. Use the environment. Background technique [0002] Modern office chairs have the following two problems: [0003] One: Most of the existing seats adopt the form of an integral chair back. The inclination angle of this type of chair back is mostly between 90 degrees and 115 degrees. It is difficult to provide support for the waist of the human body in a forward sitting posture. A pillow is placed at the back of the seat to avoid muscle fatigue caused by the lumbar suspension. The back pressure is supported by the shoulder blades and the spine when the human body is sitting backwards. The arc and inclination angle of the back support, as well as what kind of back support f...
