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

Embodiment 1

[0030] like figure 1 As shown, an experimental seat for testing the spine curve in human sitting posture includes a seat body, and the seat body includes a chassis, four physiological bending point supports (including cervical curvature transverse support E, thoracic curvature transverse support F, lumbar Curved horizontal support G, sacral curved vertical support C), four physiological bending point support (including cervical curvature support I, thoracic curvature support J, lumbar curvature support K, sacral curvature support H), sliding mechanism D and Sit board L.

[0031]The underframe includes a front vertical support A of the seat board, a rear vertical support B of the seat board and a base. The top of the vertical support B behind the board is rotatably connected, and the bottoms of the front vertical support A of the seat board and the rear vertical support B of the seat board are all fixedly connected on the base. The top of the sacral curvature vertical support...

Embodiment 2

[0052] like image 3 and Figure 4 As shown, the experimental seat for testing the spine curve of human sitting posture provided by Embodiment 2 has basically the same structure and function as that of Embodiment 1, and the differences mainly lie in:

[0053] Among them, the two front vertical supports A of the seat board are fixedly connected with the steel pipe 1 and the steel pipe 3 3 by welding, and the bottoms of the two rear vertical supports B of the seat board are slidably connected with the steel pipe 1 and the steel pipe 3 3, and the specific sliding connection method is as follows: : the bottom of the rear vertical support B of the sitting board is provided with a slide block 4, and the steel pipe one 1 and the steel pipe three 3 are provided with a chute 5, and the sliding block 4 and the chute at the bottom of the rear vertical support B of the sitting board 5 sliding connections (such as image 3 and Figure 4 shown); or, the two rear vertical supports B of th...

Embodiment 3

[0060] The experimental seat for testing the spine curve of the human sitting posture provided in Example 3 has basically the same structure and function as that of Example 1, the main differences being:

[0061] The front vertical supports A of the two seat boards are fixedly connected to the steel pipe 1 and the steel pipe 3 3 by welding, and the bottoms of the rear vertical supports B of the two seat boards are hinged to the steel pipe 1 and the steel pipe 3 3; or, two of the seat boards The rear vertical support B is fixedly connected with steel pipe one 1 and steel pipe three 3 by welding, and the bottoms of the front vertical support A of the two seat plates are all hinged with steel pipe one 1 and steel pipe three 3.

[0062] In addition to the functions described in Embodiment 1, this embodiment 3 also has the function of adjusting the horizontal angle of the seat L. The height and horizontal angle of the seat L relative to the base in this embodiment 3 can be adjusted....

Abstract

The invention discloses an experimental seat for testing a human body sitting posture spine curve. The experimental seat comprises a bottom frame, a cervical curvature transverse support, a thoracic curvature transverse support, a lumbar curvature transverse support, a sacral curvature vertical support, a cervical curvature backup plate, a thoracic curvature backup plate, a lumbar curvature backup plate, a sacral curvature backup plate, a sliding mechanism and a seat plate. The seat plate is rotationally connected with a seat plate front vertical support and a seat plate rear vertical support, the sacral curvature vertical support is rotationally connected with the sacral curvature backup plate, the cervical curvature transverse support, the thoracic curvature transverse support and the lumbar curvature transverse support are all slidably connected with the sliding mechanism, the cervical curvature transverse support is rotationally connected with the cervical curvature backup plate, the thoracic curvature transverse support is rotationally connected with the thoracic curvature backup plate, and the lumbar curvature transverse support is rotationally connected with the lumbar curvature backup plate; and the seat plate front vertical support, the seat plate rear vertical support, the cervical curvature transverse support, the thoracic curvature transverse support, the lumbar curvature transverse support and the sacral curvature vertical support are all of telescopic structures. According to the experimental seat for testing the human body sitting posture spine curve, human body spine shape fitting can be achieved when a person is in a healthy sitting posture and in a comfortable state, and the healthy spine relaxing mode is further improved 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...
