Abstract

A chair with a sitting posture detection device comprises a measurement circuit and four pressure sensors respectively arranged under four chair legs. The measurement circuit also includes a processor, a pre-amplifier, an analog-to-digital converter and an input / output interface, the four pressure sensors respectively detect pressures applied to the four chair legs, the pressure signals are converted by the analog-to-digital converter into digital signals and transmitted to the processor, and the processor compares the digital signals with pressure values obtained by the four pressure sensors under the condition of a correct sitting posture and then outputs a deviation between the position of center of gravity of a person at present and the position of center of gravity of a person with correct sitting posture. When the sitting posture of a person changes, the center of gravity changes as well, the changed pressures detected by the pressure sensors on the four chair legs are compared with the pre-stored pressures detected by the pressure sensors on the four chair legs under the condition of correct sitting posture, and if the deviation exceeds a set range, it is judged as poor sitting posture. The invention can real-time detect a poor sitting posture so as to protect the spine and the body shape.

Description

technical field [0001] The present invention relates to articles for human life, in particular to furniture, in particular to a seat, in particular to a seat with a sitting posture detection device. Background technique [0002] People who sit on chairs for a long time are prone to bad sitting posture, which affects the spine and body shape. In the prior art, the seat cannot provide help to maintain a correct sitting posture. Contents of the invention [0003] The object of the present invention is to provide a seat with a sitting posture detection device. The seat with a sitting posture detection device solves the technical problem that the seat cannot detect the sitting posture of a person in the prior art. [0004] This seat with the sitting posture detection device of the present invention comprises seat board, back board, chair frame, measuring circuit and four pressure sensors, and four chair feet are included in the described chair frame, and described seat board a...
