a sofa structure

Abstract

The invention relates to a novel sofa structure comprising a seat frame, a backrest, a seat cushion and armrests mounted on the sides of the seat frame. The seat cushion is placed on the upper surfaceof the seat frame, and the backrest is located on the seat cushion. The seat cushion comprises a wrap layer, a cotton mat layer and a force equalizing layer are disposed inside the wrap layer, and the cotton mat layer is disposed on the upper surface of the force equalizing layer. The force equalizing layer comprises a plurality of force equalizing assemblies uniformly distributed on the same layer. Each force equalizing assembly includes a bracket, a diaphragm spring and a support plate, wherein the central portion of the support plate perpendicular to the surface of the support plate is provided with a guide post perpendicular to the surface of the seat cushion, the guide post faces the bracket, the position of the bracket opposite to the guide post is provided with a guide hole matchedwith the guide post, the diaphragm spring is installed between the bracket and the support plate, and the center line of the diaphragm spring coincides with the center line of the guide post. The novel sofa structure has the advantage of improving the comfort due to the fact that the seat cushion provides approximate counterforce to all parts of the human body when a user sits on the seat cushion.

Description

technical field [0001] The invention relates to the technical field of a sofa, in particular to a sofa structure. Background technique [0002] Sofa is a kind of upholstered chair, which belongs to a kind of furniture. Because sofa is more comfortable to use in people's life, it is widely used in modern life. [0003] The sofa includes a seat frame, a seat cushion, an armrest and a backrest. The seat cushion is placed on the upper surface of the seat frame. and rest against the backrest. The seat cushion of the existing sofa is usually a cotton pad. When the user sits on the seat cushion, the seat cushion is sunken downwards, and then the area where the seat cushion contacts the human body is relatively large, so that the person sitting on the seat cushion feels more comfortable. Soft and relatively comfortable. [0004] However, in such a structure, when the human body is in contact with the seat cushion, the seat cushion deforms, and the greater the deformation of the s...

Problems solved by technology

[0004] However, in such a structure, when the human body is in contact with the seat cushion, the seat cushion deforms, and the greater the deformation of the seat cushion, the greater the reaction to the human body, so that the extrusion force received by different parts of the human body varies greatly, which in turn will cause the human body to lose weight. Excessive force on the local position, causing discomfort
