Description

A kind of student chair for correcting sitting posture

Technical field

The chair that can be tilted and rotate with human body the present invention relates to a kind of chair to correct faulty sitting posture, especially seat, belongs to In household and study, office realm.

Background technology

Currently, the construction of well known student's chair for learning is connected and fixed by the chair back, seat and chair legs, people It sits on and is used to support body, still, people are with chair come when being uprightly seated and write, human body presents two different State, since seat is horizontal changeless, when upright be seated, the pressure for contacting the body part of seat is relatively uniform , body back leans against on the chair back, and nature is presented in backbone, and when writing, and body can turn forward, the center of gravity of body to Preceding movement, in order to keep the balance of body, contact seat leg muscle pressure in front that can increase, time slightly long leg can very not It is comfortable, body be break away from this pressure brought to leg it is uncomfortable, can make lower body half costula column backward naturally or It is bent to side, forms the posture of hunch, correct sitting posture is cannot keep, for a long time in this way, being not only unfavorable for body bone The healthy growth of bone, and be easier to cause the body illnesses such as scoliosis, hunchback, myopia.

Invention content

To solve the above-mentioned problems, overcome the shortcomings of that existing study chair is not easy to human body and keeps correct writing sitting posture, The present invention provides a kind of chair, which can not only support human body, and seat can between different sitting postures random conversion angle, make Human body more easily keeps the sitting posture being good for your health, to achieve the purpose that correct faulty sitting posture.

The technical solution adopted by the present invention to solve the technical problems is：In seat（3）With connecting cross beam（6）Between install additional A kind of mechanism that can be freely rotated within a certain angle, the rotating mechanism is by seat holder（7）, shaft（9）, axis card Spring（10）, overarm brace（8）, supporting rod（12）, adjusting knob（11）Composition, when people need upright sitting, seat（3）With Human body sitting posture keeps horizontal, and nature extended position is presented in backbone, and when people need to write, forward lean, seat stress occurs Change, is increased by downward pressure before seat, rotated by the rotating mechanism being incorporated in below seat, turned downwards before seat Dynamic certain angle contacts adjusting knob（11）Stop behind top, seat（3）Balanced with body contacting portion pressure, backbone can be compared with Nature extended configuration is readily kept, the sitting posture grown up healthy and sound conducive to backbone bone is formed with, reaches the mesh that nature corrects faulty sitting posture 's.

The invention has the advantages that people can arbitrarily convert between upright sitting posture and writing sitting posture, and easier The sitting posture conducive to backbone bone health is maintained, achievees the purpose that nature corrects faulty sitting posture.
