Experimental chair for testing spine curve of human body in sitting posture

Abstract

The invention discloses an experimental chair for testing a spine curve of a human body in a sitting posture. The experimental chair comprises a bottom frame, a neck flexure transverse support, a chest flexure transverse support, a waist flexure transverse support, a sacral flexure vertical support, a neck flexure backup plate, a chest flexure backup plate, a waist flexure backup plate, a sacral flexure backup plate, a sliding mechanism and a sitting plate, wherein the seat plate is rotatably connected with a seat plate front vertical support and a seat plate rear vertical support; the sacralflexure vertical support is rotatably connected with the sacral flexure backup plate; the neck flexure transverse support, the chest flexure transverse support and the waist flexure transverse supportare all slidably connected with the sliding mechanism; the neck flexure transverse support is rotatably connected with the neck flexure backup plate; the chest flexure transverse support is rotatablyconnected with the chest flexure backup plate; the waist flexure transverse support is rotatably connected with the waist flexure backup plate; and the seat plate front vertical support, the seat plate rear vertical support, the neck flexure transverse support, the chest flexure transverse support, the waist flexure transverse support and the sacral flexure vertical support are all of a telescopic structure. The experimental chair provided by the invention can realize spine form fitting of the human body in a healthy sitting posture and a comfortable state of the human body, and further improves the healthy spine relaxing mode under the condition that the comfort degree is guaranteed.

Description

technical field [0001] The technology relates to an experimental seat, in particular to an experimental seat for testing the spine curve of a human sitting posture. This experimental seat adjusts the height and depth of the support of the four physiological bending points of the human body. This adjustment method mainly determines the main support points of the cervical spine, thoracic spine, lumbar spine, and sacrum, and measures the spine angles of the four physiological bending points. , to explore the comfort of the human body's healthy spine curve in sitting posture and the human body's sitting posture spine curve in a comfortable state. Background technique [0002] Upholstered sofas offer a higher level of comfort and have therefore seen an increasing proportion of use in domestic environments in recent years. At the same time, the comfort of the internal support of the upholstered sofa is high, and the time for people to maintain a uniform posture on the sofa become...

AI Technical Summary

Problems solved by technology

At the same time, the comfort of the internal support of the upholstered sofa is high, and the time for people to maintain a uniform posture on the sofa becomes longer, which is easy to cause fatigue and puts greater pressure on the human spine.

In addition, the subjectively comfortable sitting posture may not be in line with the healthy development of the human spine, so how to further improve the healthy spinal relaxation method while ensuring comfort is still inconclusive
