[0016] The utility model will be further described in detail below with reference to the drawings.

[0017] Referring to Figs. 1-4 The sofa backrest shaping cotton structure comprises a body 1, reinforcing columns 2 are arranged on the two sides of the body 1, the thickness of the reinforcing columns 2 is greater than the thickness of the body 1, the reinforcing columns 2 and the body 1 are an integral forming structure, the body 1 is arranged in an arc shape, and the bottom end of the reinforcing columns 2 exceeds the bottom end of the body 1. Therefore, the reinforcing columns 2 and the body 1 are both completed by shaping cotton in an integral shape, and the back surface of the reinforcing columns 2 is consistent with the arc of the back surface of the body 1. The reinforcing columns 2 can improve the support strength of the entire structure, and the body 1 and the reinforcing columns 2 jointly shape the sofa backrest, thereby ensuring the support effect.

[0018] By being provided with the body 1 and the reinforcing column 2, the overall bearing strength can be increased through the reinforcing column 2, thereby facilitating the increase of the length of the body 1 and the area of the whole structure, and further suitable for the sofa backrest with a larger area.

[0019] The top end of the body 1 is provided with the bearing part 3, the front end face of the bearing part 3 is beyond the front end face of the body 1 and the reinforcing column 2, and the bearing part 3 is located above the reinforcing column 2. Therefore, the cross section of the bearing part 3 is relatively larger than that of the body 1, which facilitates the increase of the acting area of the bearing part 3, the exertion of external force on a larger area of the bearing part 3 and the release of the acting force on the bearing part 3, thereby effectively avoiding the above problems. The bearing part 3 and the body 1 are integrally formed.

[0020] The lower end face of the bearing part 3 is formed with the first mounting groove 31 extending from one side of the reinforcing column 2 to the other side of the reinforcing column 2, and the first mounting groove 31 is provided with the embedded plate 4. The embedded plate 4 is a flat plate directly embedded into the first mounting groove 31, and the bottom end face of the embedded plate 4 is flush with the lower end face of the bearing part 3. In order to improve the combination stability of the embedded plate 4 and the bearing part 3, the embedded plate 4 is fixed in the first mounting groove 31 by gluing.

[0021] By installing the embedded plate 4 in the first mounting groove 31, the bearing strength of the bearing part 3 can be improved, and meanwhile, the embedded plate 4 located in the first mounting groove 31 can ensure the softness of the bearing part 3.

[0022] The sofa backrest shaping cotton structure of the utility model further comprises the inlay 5, the inlay 5 is two and is arranged on the reinforcing column 2 on the two sides respectively; the two inlays 5 are vertically arranged.

[0023] The side of the two reinforcing columns 2 close to the body 1 is provided with the second mounting groove 21, and the inlay 5 is arranged in the corresponding second mounting groove 21.

[0024] In order to improve the stability of the installation of the inlay 5, the inlay 5 is fixed in the second mounting groove 21 by gluing, and the front end face of the inlay 5 is flush with the front end face of the reinforcing column 2. Through the inlay 5, the strength of the reinforcing column 2 can be further improved, the whole body 1 is supported, and the body 1 can maintain the required shape of the sofa backrest.

[0025] The thickness of the middle part of the reinforcing column 2 is greater than that of the upper and lower ends, and the front side face of the reinforcing column 2 is a vertical face. Since the bottom end of the reinforcing column 2 is beyond the bottom end of the body 1 and the thickness of the bottom end of the reinforcing column 2 is smaller than that of the middle part, the bottom end of the reinforcing column 2 is conveniently matched with other structures of the sofa, and the installation is convenient.

[0026] The above is only the preferred embodiment of the present application, and it should be pointed out that, for those skilled in the art, without departing from the creative concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
