A double-arc curved shape is formed, the chair back has a steradian structure, the function of supporting the back and the vertebra can be fully realized, the burden of the vertebra is lightened, people do not feel tired when lying on the chair back, the comfort level is improved, and the human vertebra is prevented from being injured due to long-term bad sitting posture.
Description
Technical field
The present invention relates to a kind of backrest of chair, especially a kind of sterad chair back of suitable human vertebra.
Background technology
The in the market design of chair is not brought into play effect, the especially backrest of back well to an overfill protection of lumbar vertebrae.Chair used in everyday only has simple backrest function, lacks the support that adapts to vertebra normalized curve radian, and long-term use can affect people's sitting posture, is unfavorable for the health of vertebra, the situations such as backache will occur in the course of time; Particularly when the people feels that fatigue leans against on the chair, whole-body muscle will be relaxation state, only have vertebra to bear the weight of the whole upper part of the body, extra pressure all has been added on the spinal disc, be difficult to obtain comfortable, healthy posture, incorrect sitting-pose finally easily causes lumbar muscle strain and waist dish outstanding for a long time.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide the chair back that is fit to the human vertebra curve-shape electronic radian, can better bring into play the supporting role of lumbar vertebrae, improve comfort level.
The present invention solves the technical scheme that its problem adopts:
A kind of sterad chair back of suitable human vertebra, comprise back frame and the support component that is fixed on the back frame, it is characterized in that: described back frame also comprises upper side frame, lower frame and left and right sides frame, described upper side frame and lower frame have a crooked arc, connect and compose arc-shaped concave with vertical left and right sides frame, be half barrel shape structure, the S-type structure of described support component, vertically be arranged in side by side and consist of S type curved-surface structure between upper side frame and the lower frame, form from top to bottom two arcuate structures, at the horizontal and vertical radian that adapts to human body back curve that all is provided with, form the structure of sterad, very large supporting role is played at back and vertebra, allowed the people lean against for a long time and can not feel tired on the chair back.
Further, arc minimum point and the vertical height between the peak of described upper side frame and lower frame are 1.5cm-2cm, upper side frame and lower frame are with identical radian measure, back frame with left and right sides frame formation, the horizontal natural curve of its curve radian and human body back adapts, human body back can fully be contacted with backrest, and the back obtains maximum support effect.
Further, the antecurvature salient point of two curve arcs of described support component and the concave point of the palintrope respectively vertical height of corresponding back frame center line are 1cm-2cm, described support component has the two arcuate structures of S type, the natural vertical curve of its curve radian and human body ridge vertebra adapts, make human vertebra and support component can be fully near, vertebra obtains maximum support effect.
Further, the first half arc of described support component is lower than the arc-shaped concave of described back frame, the Lower Half arc of described support component is higher than the vertical plane at the left and right sides frame place of described back frame, described support component is arranged side by side and is consisted of S shape curved surface, the first half arc of described curved surface is concave shape, and the Lower Half arc forms and protrudes shape.
Further, the arrangement pitches vertically arranged side by side of described support component is the width of support component, and the gap between the adjacent support member provides ventilative function, the Effective Raise comfort level.
Further again, top and the bottom of described upper side frame are circular shape, described left and right sides scuncheon is fixed with joint pin, described joint pin is provided with corresponding spiro keyhole position with the left and right sides frame, the top of described joint pin is provided with the arc groove that the bottom circular shape with upper side frame is complementary, the arc-shaped surface of arc groove and upper side frame bottom is bonded with each other, so that backrest border structure close and firm more.
The invention has the beneficial effects as follows: the back of suitable human vertebra provided by the invention, it all is made of metal material, sturdy and durable, bear load-carrying strong, structure with sterad, the mechanics feature that meets human body back and vertebral curve, in the time of on being sitting in chair, laterally can bring into play fully the supporting role of back and vertebra with longitudinally arc design, help vertebra to support our health, alleviate the burden of vertebra, allow the people lean against for a long time and can not feel tired on the chair back, protect human vertebra to avoid the damage that causes because of long-term incorrect sitting-pose, the arcuate structure on the top of backrest, alleviate because collision causes bump pressure, play the effect of protection human body; Simultaneously back and the chair back near the time, the gap between the support component can provide good permeability, greatly improves comfort level.
