Foldable chair-back structure

Abstract

The invention relates to a foldable chair-back structure comprising a chair-back body and a folding part. The folding part is installed on the upper part of the chair-back body, the folding part is hinged with a rear side position of the chair-back body, the folding part is provided with a transverse arc-shaped projection, first magnetic blocks with opposite polarities are respectively arranged on the back parts of the folding part and the chair-back body, and second magnetic blocks with opposite polarities are respectively arranged on docking positions of the folding part and the chair-back body. The folded folding part and the chair-back body can be automatically absorbed and connected by magnetism through the first magnetic blocks, the unbent folding part and the chair-back body can be automatically absorbed and connected by the magnetism through the second magnetic blocks, the arc-shaped projection of the connected folding part can play a role of a pillow, and a person can comfortably lie down for rest only if the chair-back is slantly placed. By adopting the design, the function of lying down for rest of a plurality of advanced seat chairs can be realized by a common seat chair after simple improvement, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to an office seat structure, specifically a chair back structure. Background technique [0002] Existing office chairs, with a simpler structure, can only provide the function of sitting and leaning. If you need to lie on your back and rest on the seat, you need to carry out a very complicated design on the structure of the seat, which also improves the safety of the seat itself. Design and manufacturing costs, a seat that can provide supine rest, is unaffordable for ordinary employees. Like this just raised a problem of how to design a kind of seat structure that is simple in structure and can provide supine resting function. Contents of the invention [0003] Based on the above problems, the present invention provides a chair back structure that can be folded backwards. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A foldable chair back structure, comprising ...
