Abstract
The invention discloses a bidirectional back-rest chair comprising a chair back, a chair back connecting rod, a seat, a supporting shaft and chair legs, wherein one end of the chair back connecting rod is fixedly connected with the chair back, and the other end of the chair back connecting rod is arranged on the supporting shaft; one end of the supporting shaft is rotatably connected with the seat, and the other end of the supporting shaft is fixedly arranged on the chair legs; and the seat is set to be of a saddle type structure. The back-rest chair disclosed by the invention has forward and backward sitting posture ways; due to the adoption of the structural design of the saddle type structure of the seat, pressure borne by the waist and the hips can be dispersed on upper legs in a sitting posture state, the interaction force between the upper legs and the seat can be effectively buffered and released, and a sitting posture can be kept for a long time. The surface of the seat is provided with air holes beneficial to heat radiation as well as clean and dry keeping in hip regions. In addition, the chair back is also provided with a detachable working platform, so that a person can conveniently work when backwards sitting on the chair, and the technical problems that the traditional chair back is discomfortable and the sitting posture cannot be regulated are solved.
Description
Technical field
The present invention relates to a kind of chair, relate in particular to a kind of reversible chair.
Background technology
Most of chairs of design are forward-type chair at present, can only lean against the chair back and sit, and forward-type chair is in the time of long-time use, and human body is affected and hunch by self gravitation easily, form improper sitting posture custom.This forward-type chair is in normal sitting position situation, pressure concentration is above the waist at waist and buttocks, and the in the situation that of improper sitting posture, pressure peptizaiton is at positions such as shoulder, back, waist, vertebra, buttocks and thighs, be subject to incorrect sitting-pose to affect the pressure that waist and buttocks bear be 4.6 times in normal sitting position situation, local nerve system is oppressed for a long time, has a strong impact on inner blood circulation, easily causes the generation of lumbar disc disease.Therefore, existing chair exists the technical problem that sitting posture direction is single, and then designs a comfortablely, and capable of regulating sitting posture direction, keeps the chair of human normal sitting posture to seem particularly necessary, improves greatly especially to one of prior art.
Summary of the invention
The object of the present invention is to provide a kind of reversible chair, to solve the nonadjustable technical problem of above-mentioned existing chair sitting posture direction.
The designed technical scheme of the present invention is as follows:
A kind of reversible chair, wherein, comprise the chair back, chair back connecting rod, seat support, back shaft and chair pin, one end of described chair back connecting rod is fixedly connected with the chair back, the other end is arranged on back shaft, described back shaft one end and seat support are rotatably connected, and the other end is fixedly installed on chair pin, and described seat support is set to saddle type structure.
Described reversible chair, wherein, described seat support is set to dichotomous saddle structure.
Described reversible chair, wherein, also comprises workbench, and described workbench is dismountable to be arranged on chair back connecting rod.
Described reversible chair, wherein, described seat support also comprises chassis, and described chassis is fixedly connected with seat support, and described chassis and back shaft are rotatably connected.
Described reversible chair, wherein, the width of described chair back connecting rod is set to: 15～30 centimetres
Described reversible chair, wherein, described seat support surface is provided with air-vent.
Described reversible chair, wherein, also comprises load carrier, rotatable and telescopic being arranged on load carrier of described back shaft.
Shown reversible chair, wherein, described chair back connecting rod outside is provided with rotary switch, and described workbench is provided with installing hole, and described chair back connecting rod and workbench removably connect by rotary switch.
In the present invention, chair has two kinds of sitting posture modes of forward and backward, the saddle type structural design of seat support can be dispersed in the pressure that under sitting posture state, waist and buttocks bear on thigh, and the structure of saddle type can effectively cushion and discharge the interaction force between thigh and seat support, can keep for a long time sitting posture.The air-vent that seat support surface arranges contributes to the heat radiation of seat area, keeps clean dry and comfortable.When user sits forward for a long time, can sit towards the metathorax arm-chair back of the body by turning chair seat surface, not only discharged releive nervous system but also can alleviate spinal load of back pressure, in addition, the chair back is also provided with detachable workbench, when to recoil, convenient work, has solved the technical problem that existing chair is uncomfortable, cannot adjust sitting posture.
