Sofa

Abstract

The sofa comprises a bottom plate and armrest plates symmetrically arranged at the upper end of the bottom plate, a backrest plate is further arranged at the position, located between the armrest plates, of one side of the upper end of the bottom plate, a cushion unit capable of adjusting the sinking degree is arranged at the upper end of the bottom plate, and a backrest unit used for limiting the back of a human body is arranged on the side, close to the cushion unit, of the backrest plate; the invention can solve the following problems in the use process of the existing sofa: after the seat on the sofa cushion is pressed by people for a long time, the elasticity of the seat is generally reduced, and the seat sinks downwards, so that the comfort degree and the aesthetic degree of the sofa cushion are reduced; the elasticity degree of the sofa cannot be adjusted, and when people in the same family have different requirements on the sinking degree of the sofa, the existing sofa cannot meet the use requirements; when the back of a person leans against the sofa and inclines towards one side, the backrest of the existing sofa cannot limit the inclined back of the person, so that the inclined state is difficult to keep.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a sofa.

For an accurate comparison, for example, the Chinese Patent Publication No. CN111466742A discloses a sofa; when it is in use, the main body splicing mechanism is provided with an edge connecting plate, a main body connecting plate, an assembled connecting plate, a splicing groove, a main body tele...

AI Technical Summary

Problems solved by technology

[0004] Yet above-mentioned sofa also has some deficiencies in the process of actual use: 1, when people sit on the sofa, usually can sit on the fixed position on the sofa cushion, yet the fixed position on the sofa cushion has been subject to the people's for a long time. After sitting pressure, it usually reduces its elasticity and sags downward, which reduces the comfort and aesthetics of sofa cushions

[0005] 2. When needing to lie down on the sofa, because some people prefer to sleep on a harder sofa, that is, a sofa that is still relatively flat after being pressed by the gravity of the human body; while others like to sleep on a softer sofa, It is a sofa that will be sunken in different degrees after being pressed by the gravity of the human body, but the degree of elasticity of the above sofa is not adjustable. Reduced suitability for the sofa above

[0006] 3. Since the sofa in the living room is usually facing the TV, and the sofa in the living room usually has at least three seats, when there is only one person sitting on the sofa watching TV, they usually sit in the middle of the sofa in order to face the TV. Both sides cannot reach the armrests. However, in order to adjust the comfort of the sitting posture, the back of the person may tilt to the left or right. At this time, the backrest of the above sofa cannot limit the tilted back of the human body As a result, the person's back is easy to slide down after tilting, making it difficult to maintain the tilted state, and reducing the comfort of the sofa backrest
