Sitting posture supervising chair

Abstract

The invention discloses a sitting posture supervising chair, comprising chair legs, a sitting plate, a backrest, an inclined detection switch and a leaning detection switch. The inclined detection switch is used for detecting a state that the sitting plate is pressed; and the leaning detection switch is used for detecting a state that the backrest is pressed. The inclined detection switch and the leaning detection switch are connected with a control circuit; and the control circuit judges whether the sitting posture of a person is correct or not according to the on-off state of the inclined detection switch and the leaning detection switch and drives a prompting device to alarm after the sitting posture is detected to be improper or the lasting time for maintaining the improper sitting posture reaches predetermined time. A detection device is additionally arranged on the chair which must be used when working or learning, the sitting posture supervising chair enables the chair to have a supervision function of detecting the sitting posture of the human body. Because a user is allowed to sit on the chair with the improper sitting posture within a short time, the sitting comfort and the psychology receptivity of the user are improved on the premise of no influence on backbone, lumbar vertebra and eyesight of the user.

Description

technical field [0001] The invention belongs to the technical field of seats, and in particular relates to a seat with a sitting posture monitoring function. Background technique [0002] As we all know, the sitting posture of bending over, bowing the head, and shrugging the shoulders is a habitual bad sitting posture, which occurs unconsciously and is difficult to control through people's consciousness. However, over time it will cause people to suffer from diseases such as spine, lumbar spine, cervical spine and myopia. At present, although many patented technologies and products have emerged to prevent spinal and lumbar diseases and myopia by correcting bad sitting posture, such as posture correction brackets or posture correction straps. However, these products often have a common disadvantage, that is, once the user wears or uses the corrective product, he must be constrained by it and always maintain a correct posture, so that the user is always in a forced and uncomf...

AI Technical Summary

Problems solved by technology

But the seat of this structure can't solve the problem that after the user bends down, the center of gravity of the upper body is still on the side of the chair backrest and the problem that the movable and fixed parts cannot be turned over, although the eyes can keep a certain distance from the books like this, may be Keeping the lumbar spine and spine in a bent state for a long time, failing to meet the correct sitting posture requirement of "keep the thigh and upper body basically vertical"

In addition, the seat with this structure uses complex structures such as up and down displacement detection switches, moving and fixing parts rotating devices, etc., resulting in defects such as high production costs and poor reliability in use.
