Abstract

In a chair capable of automatically adjusting a sitting posture, pressure sensors are arranged at the lower ends of four chair legs, four lifting mechanisms are arranged between a chair frame and a chair plate, and a controller is arranged in the chair frame and includes a processor, a pre-amplifier, an analog-to-digital converter, a memory, an input keyboard and a step motor driving circuit. The pressure sensors real-time transmit pressure signals to the processor, the processor separately adjusts the vertical distances between four corners of the chair plate and the chair frame via step motors when deviations between the pressures of four chair legs and the pressures obtained under the condition of correct sitting posture exceed a set range, and rotation of the step motors is stopped when the deviations are smaller than the set range. The center of gravity of a person can be changed because of inclination of the chair plate, which helps the person adjust the his/her sitting posture and restore a correct sitting posture, and at this time the processor synchronously adjusts the inclination degree of the chair plate via the four step motors. The invention can real-time rectify poor sitting posture to protect the spine and the body shape.

Description

technical field [0001] The present invention relates to daily necessities for human beings, in particular to furniture, in particular to a seat, in particular to a seat which can automatically adjust the sitting posture. 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 actively maintain the correct sitting posture. Contents of the invention [0003] The object of the present invention is to provide a seat for automatically adjusting the sitting posture, which solves the technical problem that the seat cannot actively maintain the correct sitting posture in the prior art. [0004] The seat of the present invention which automatically adjusts the sitting posture comprises a seat board, a back board, a chair frame, a controller, four pressure sensors and a power supply, and the described chair frame includes four chair feet, and the described seat...
