In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0031] Currently, for sofas, the position of the backrest on the seat cushion is relatively fixed, lacking the freedom of adjustment. The area where users sit or lie is relatively single, and they cannot freely choose a suitable position, reducing the user experience. The present application provides a sofa to solve the above technical problems.

[0032] As Figure 1 shown, the present application provides a sofa, including a seat cushion 10 and a backrest 20. The backrest 20 is placed on the seat cushion 10 and can move on the seat cushion 10. The backrest 20 includes a bottom surface 201 facing the seat cushion 10. The bottom surface 201 is provided with anti-slip protrusions 23. The anti-slip protrusions 23 are in contact with the seat cushion 10.

[0033] Since the backrest 20 can move on the seat cushion 10, the position of the backrest 20 can be adjusted, improving the freedom of the sofa. The user can place the backrest 20 at the corresponding position according to the needs. At the same time, by providing the anti-slip convex portions 23 on the bottom surface 201, it is possible to prevent the backrest 20 from sliding during the user's leaning process, improving the user experience.

[0034] Please refer to Figure 2 As shown, the backrest 20 includes a leaning surface 202 and a back surface 203. The leaning surface 202 and the back surface 203 are arranged oppositely. The leaning surface 202 can be inclined, facilitating the user to lean and improving the user experience.

[0035] Please refer to Figure 3 As shown, the backrest 20 includes a main body 21 and an anti-slip member 22. The anti-slip member 22 is provided on the side of the main body 21 facing the seat cushion 10. The anti-slip convex portions 23 protrude from the anti-slip member 22 towards the seat cushion 10. Since the anti-slip member 22 is located on the side of the main body 21 facing the seat cushion 10, when the backrest 20 is placed on the seat cushion 10, the weight of the main body 21 is completely applied to the anti-slip member 22, thereby increasing the friction between the backrest 20 and the seat cushion 10 and further reducing the probability of the backrest 20 sliding during the user's leaning process, improving the user experience.

[0036] The anti-slip member 22 can be an anti-slip cloth, which has a simple structure, is convenient for production, and can be freely cut and spliced according to the structural shape of the main body 21. In this embodiment, the bottom surface 201 of the backrest 20 is the surface of the anti-slip member 22 facing the seat cushion 10. In other embodiments, the specific structural form of the anti-slip member 22 is not limited.

[0037] The backrest 20 can be an integral component. When the user moves the backrest 20, the backrest 20 can be moved as a whole, improving the moving convenience of the backrest 20 and enhancing the user experience. Taking the anti-slip member 22 as an anti-slip cloth as an example, the anti-slip member 22 can be fixed to the main body 21 through processes such as sewing. The user only needs to move the main body 21 to drive the entire backrest 20 to move together, without the need to separately move the main body 21 and the anti-slip member 22, improving the moving convenience of the backrest 20.

[0038] The anti-slip convex portions 23 include a contact surface 230 that abuts against the seat cushion 10. The contact surface 230 can be in the shape of a spherical arc surface. When the user leans on the backrest 20, the anti-slip convex portions 23 will deform. During the leaning process, the user's posture will change, causing the deformation direction of the anti-slip convex portions 23 to change accordingly. Since the contact surface 230 is in the shape of a spherical arc surface, no matter how the anti-slip convex portions 23 deform, the contact surface 230 and the seat cushion 10 can always maintain a large contact area, ensuring the friction between the backrest 20 and the seat cushion 10, preventing the backrest 20 from sliding, and improving the user experience.

[0039] Please refer to Figure 4 As shown, the number of the anti-slip convex parts 23 is set to be multiple. The multiple anti-slip convex parts 23 are arranged in an array on the bottom surface 201. Through the anti-slip convex parts 23 arranged in an array, the friction force between the backrest 20 and the seat cushion 10 can be further increased, and the user can be prevented from moving during the use of the backrest 20.

[0040] The anti-slip convex part 23 includes multiple distribution rows 231. The multiple distribution rows 231 are arranged at intervals along the depth direction of the sofa. The depth direction of the sofa can be specifically seen Figure 2 or Figure 4 the A direction in

[0041] Since the user generally sits on the seat cushion 10 along the depth direction of the sofa, by arranging the anti-slip convex parts 23 in the distribution row 231 to be aligned with the gaps 232 in the adjacent distribution row 231, the area where no anti-slip convex parts 23 are arranged for a long time in the depth direction can be avoided, and the friction force between the backrest 20 and the seat cushion 10 is further increased.

[0042] The anti-slip convex parts 23 can be arranged in an equidistant array or in a non-equidistant array. Please refer to Figure 5 and Figure 6 as shown in Figure 4 which shows an embodiment in which the anti-slip convex parts 23 are arranged in an equidistant array, Figure 5 and Figure 6 which shows an embodiment in which the anti-slip convex parts 23 are arranged in a non-equidistant array.

[0043] As Figure 5 shown, the bottom surface 201 includes a middle area 2011 and an edge area 2012. The edge area 2012 surrounds the middle area 2011. In one embodiment, the distribution density of the anti-slip convex parts 23 in the middle area 2011 is greater than that in the edge area 2012.

[0044] Since the distribution density of the anti-slip convex parts 23 in the edge area 2012 is small, when the user moves the backrest 20, the backrest 20 can be lifted from any side, and the middle area 2011 can be suspended, so that only the edge area 2012 is in contact with the seat cushion 10, which can appropriately reduce the friction force between the backrest 20 and the seat cushion 10 and reduce the difficulty for the user to move the backrest 20.

[0045] Since the distribution density of the anti-slip convex parts 23 in the middle area 2011 is large, the friction force between the backrest 20 and the seat cushion 10 can be ensured, and the user can be prevented from sliding during leaning.

[0046] Even if a relatively large force is generated during the user's leaning process, for example, when the user lies down on the backrest 20, since it is difficult for the middle region 2011 to slide, the backrest 20 will only flip to a certain extent with the edge region 2012 as the center. At this time, the force generated by the user and the overall weight of the backrest 20 will act entirely on the edge region 2012, increasing the friction between the edge region 2012 and the seat cushion 10, and still preventing slippage between the backrest 20 and the seat cushion 10.

[0047] As Figure 2 and Figure 6 shown, in another embodiment, in the direction from the leaning surface 202 to the back surface 203, that is, in the A direction shown in the figure, the distribution density of the anti-slip protrusions 23 on the bottom surface 201 gradually decreases. When the user moves the backrest 20, the user can lift the side of the backrest 20 located on the leaning surface 202, so that the area with a smaller distribution density of the anti-slip protrusions 23 contacts the seat cushion 10, so as to reduce the friction between the backrest 20 and the seat cushion 10 and facilitate the user to move the backrest 20.

[0048] Since the anti-slip protrusions 23 on the side close to the leaning surface 202 have a relatively large distribution density, it can ensure the friction between the backrest 20 and the seat cushion 10 and prevent the user from sliding during the leaning process.

[0049] In this embodiment, similar to the embodiment with a smaller distribution density of the anti-slip protrusions 23 in the edge region 2012, when the user generates a relatively large force, since it is difficult for the side of the bottom surface 201 close to the leaning surface 202 to move, the backrest 20 will only flip with the side of the bottom surface 201 away from the leaning surface 202 as the center. At this time, the force generated by the user and the overall weight of the backrest 20 will act entirely on the side of the bottom surface 201 away from the leaning surface 202, increasing the friction between the backrest 20 and the seat cushion 10 and preventing slippage between the backrest 20 and the seat cushion 10.

[0050] Therefore, in the above embodiments where the anti-slip protrusions 23 are non-equidistantly arrayed, the backrest 20 can not only relatively easily change its position on the seat cushion 10 according to the user's needs, but also prevent itself from sliding during the user's leaning process, comprehensively improving the use experience of the sofa.

[0051] In order to increase the friction, the anti-slip protrusions 23 can be made of silicone material, and the outer surface of the seat cushion 10 can be made of leather material or artificial leather material. It is possible that only the anti-slip protrusions 23 are made of silicone material. It is also possible that only the outer surface of the seat cushion 10 is made of leather material or artificial leather material.

[0052] In other embodiments, in order to reduce production costs, the anti-slip protrusions 23 can be made of plastic, and the outer surface of the seat cushion 10 can be made of fabric. It is possible that only the anti-slip protrusions 23 are made of plastic. It is also possible that only the outer surface of the seat cushion 10 is made of fabric. The specific material types of the seat cushion 10 and the anti-slip protrusions 23 are not limited.

[0053] Please refer to Figure 7 as shown in the figure, the size of the backrest 20 in the length direction of the sofa is smaller than the size of the seat cushion 10 in the depth direction of the sofa. That is, Figure 7 the length of D1 in the figure is less than the length of L2. This setting further improves the freedom of the sofa. When the user moves the backrest 20, the entire backrest 20 can be placed laterally, so that the side with the length of D1 on the backrest 20 can be arranged opposite to the side with the length of L2 on the seat cushion 10. At this time, the backrest 20 can be used as an armrest.

[0054] As Figure 8 shown in the figure, the backrest 20 can be in an L shape, so that part of the backrest 20 can be leaned on and part can be used as an armrest, further improving the use experience of the sofa. In other embodiments, the backrest 20 can also be square or the like.

[0055] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principle of this application shall be included within the scope of protection of this application.
