[0016] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 3, which is a schematic structural diagram of a sofa cushion with an adjustable backrest provided by the present utility model. The sofa cushion with an adjustable backrest includes a sofa backrest 10, a sofa seat cushion 20 attached to the sofa backrest 10, a backrest cushion 30 disposed on the sofa seat cushion 20, and a connecting strap 40 connecting the sofa seat cushion 20 and the backrest cushion 30. It can be imagined that the sofa cushion with an adjustable backrest further includes some other functional modules, such as an adhesion structure, etc., which are well-known technologies in the art and will not be elaborated here.

[0018] The sofa backrest 10 is used to protect the sofa and provide a comfortable touch for the user. The sofa backrest 10 is a general technology and will not be elaborated here.

[0019] The sofa seat cushion 20 is attached to the sofa backrest 10. The sofa seat cushion 20 includes a sofa seat cushion body 21 and a seat cushion cover 22 attached to the outer periphery of the sofa seat cushion body 21. The sofa seat cushion body 21 includes a bearing surface 211 for bearing the user, a bonding surface 212 attached to the sofa backrest 10, a bottom surface 213 opposite to the bearing surface 211, and three side surfaces connecting the bearing surface 211 and the bottom surface 213. In this embodiment, the sofa seat cushion body 21 is made of a high resilience material, such as shaped sponge. The seat cushion cover 22 is used to protect the sofa seat cushion body 21 from getting dirty and reduce damage to extend its service life. The sofa seat cushion 20 is a general technology and will not be elaborated here.

[0020] The cushion 30 is disposed at the connecting corner of the sofa seat cushion 20 and the sofa backrest 10 and is supported by the sofa backrest 10. The cushion 30 is connected to the sofa seat cushion 20 via the connecting belt 40, and the position of the cushion 30 on the sofa seat cushion 20 is adjusted by the connecting belt 40, so that the cushion 30 is not easily dropped from the sofa seat cushion 20. The cushion 30 is used to provide support for the user's waist and back and provide a comfortable touch for the user. The cushion 30 includes a cushion body 31, a cushion cover 32 disposed on the outer periphery of the cushion body 31, and a zipper 33 disposed on the cushion cover 32. In this embodiment, the cushion 30 is provided in a cylindrical shape, and the cushion 30 is provided with a curved surface 311. The curved surface 311 of the cushion 30 is attached to the receiving surface 211 of the sofa seat cushion 20. Since the setting of the curved surface 311 increases the contact area between the user and the cushion body 31 and better conforms to the waist curve of the human body, the pressure of the cushion 30 on the user is reduced, thereby reducing the discomfort caused by the user leaning on the sofa for a long time. The axial length of the cushion body 31 is equal to the length of the connection between the receiving surface 211 and the bonding surface 212, so that the cushion 30 provides complete support for the user. The cushion cover 32 is used to protect the cushion body 31 from being dirty and reduce damage to extend the service life. The zipper 33 is disposed along the axial direction of the cushion 30, and the length of the zipper 33 is greater than two-thirds of the axial direction of the cushion 30, so as to facilitate the disassembly and assembly of the cushion cover 32 on the cushion body 31, thereby facilitating the cleaning of the cushion cover 32. The position of the cushion 30 on the sofa seat cushion 20 is related to the following connecting belt 40, and will be specifically described in combination with the following connecting belt 40.

[0021] The connecting belt 40 connects the sofa cushion 20 and the cushion 30. The width of the connecting belt 40 is less than or equal to the axial length of the cushion 30. One end of the connecting belt 40 is arranged on the zipper 33 of the cushion cover 32. Preferably, the connecting belt 40 is arranged on the lower side of the zipper 33. When the cushion 30 is arranged on the sofa cushion 20, the zipper 33 faces the user, so as to facilitate the disassembly and assembly of the cushion cover 32. Since the connecting belt 40 is arranged close to the zipper 33, when the cushion 30 is arranged on the sofa cushion 20, the zipper 33 is located below the cushion 30, thus preventing the user from contacting the zipper 33 during use and avoiding affecting the comfort of the user. The other end of the connecting belt 40 is arranged on the seat cushion cover 22 at the connection between the receiving surface 211 and the adhering surface 212 of the sofa cushion body 21. The connecting belt 40 turns towards the receiving surface 211, and the cushion 30 is pulled by the connecting belt 40, and its arc surface 311 is attached to the receiving surface 211 of the sofa cushion 20. The connecting belt 40 has a certain length. Fold the connecting belt 40 to change the position of the connection end of the connecting belt 40 and the cushion 30 on the receiving surface 211, so as to change the position of the cushion 30 arranged on the sofa cushion 20.

[0022] During use, the connecting belt 40 is sewn on the lower side of the zipper 33 arranged on the cushion cover 32, and the sofa cushion body 21 and the cushion body 31 are placed in the cushion cover 32 and the seat cushion cover 22. Adjust the connecting belt 40 so that the connecting belt 40 turns towards the sofa cushion 20 and is attached to the receiving surface 211. The cushion 30 moves towards the receiving surface 211 accordingly. Adjust the connecting belt 40 again to control the position of the tangent point between the cushion 30 and the sofa cushion 20 on the sofa cushion 20, so as to adjust the position of the cushion 30 on the sofa cushion 20. The cushion 30 is supported by the sofa backrest 10 and is arranged at the connection between the sofa cushion 20 and the sofa backrest 10.

[0023] Compared with the prior art, a sofa cushion with an adjustable cushion provided by the utility model has an adjustable cushion arranged on the sofa cushion 20 by setting the connecting belt 40. One end of the connecting belt 40 is arranged on the cushion cover 32, and the other end is arranged on the seat cushion cover 22. The connecting belt 40 has a certain length. Fold the connecting belt 40 to change the position of the tangent point between the cushion 30 and the sofa cushion 20 on the receiving surface 211, so as to change the position of the cushion 30 arranged on the sofa cushion 20.

[0024] The above are only the preferred embodiments of the present utility model, and are not used to limit the protection scope of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are all covered within the scope of the claims of the present utility model.
