Abstract

This article relates to a chair, which consists of a backrest, a seat plate, a support frame and an armrest. A seat plate rotating device is provided to allow the seat plate to form a downward slope to the rear, and a lower portion of the support frame is configured to be longer than a predetermined length so as to prevent the fall from falling when the upper body is folded back.

According to this proposal, if the backrest is tilted to the rear with the maximum tilt while sitting on the chair, the backrest and the seatboard form a flat surface by the backrest angle adjusting device, and the center of gravity moves from the seatboard to the backrest with the center of gravity as the center of gravity. As the spring attached to the contractor contracts, the seat plate front part rotates upward about the central axis, so that the upper part of the backrest reaches the ground. In other words, if you adjust the angle of the backrest while tilting your body back while sitting on the chair, the backrest and the seat plate form a backward slope, and the lower part of the knee is the same as the sitting posture, but the upper body forms a certain angle with the head located underneath. It can relax the spine and cervical joints and improve the flow of blood in the head.
