[0002] Existing seating furniture, such as chairs, sofas, etc., can provide people with a comfortable resting position, are loved by people, and are widely used in people's home life.

[0003] Fabric sofas have a cover on the sofa body. The connection between the cover and the sofa body has problems such as complex structure, low production efficiency, or unreliable connection that affects the appearance. Utility Model Content

[0004] The purpose of the present application is to provide a cover snap-on structure, a backrest and a seat, which have a simple structure, are easy to assemble and have high connection reliability.

[0005] In a first aspect, the present application provides a face cover clamping structure, comprising a main body and a face cover, wherein the main body is connected with a clamping rib, and the face cover is connected and fixed to the clamping rib.

[0006] By adopting the above technical solution, a simple and quick structure is provided to connect and fix the face cover to the main body. The clip and the main body can be fixed by a variety of connection methods. When the main body is a plastic part, the clip and the main body can be integrally injection molded; when the main body is a sponge, the clip and the sponge can also be integrally molded when the sponge is molded; the clip can also be fixed as a whole after the main body is molded. The face cover can be fixed by clamping with the clip, or it can be connected and fixed by other connecting parts. Since the clip can adapt to different shapes and sizes of face covers, this structure can be suitable for various types of face cover connections. This connection structure has a simple structure and is easy and quick to disassemble and assemble. It can not only achieve a beautiful appearance but also greatly improve production efficiency.

[0007] In a further solution, the face cover is provided with a clamping strip, and the clamping strip and the clamping rib are connected and fixed by a clamping spring.

[0008] By adopting the above technical solution, the clamping strip facilitates the stability of the shape of the face cover and is convenient to connect with the clamping bar. The clamping strip and the clamping bar are connected and fixed by the clamping spring, which can be standardized and the connection is more firm and convenient.

[0009] In a further solution, the body is provided with a groove, and the clamping rib is arranged in the groove.

[0010] By adopting the above technical solution, the clamping rib is arranged in the groove. When connected with the face cover, the groove can hide the connection position to make the appearance more beautiful.

[0011] In a further solution, the clamping rib is partially located inside the body and partially located outside the body, and the face cover is connected and fixed to the clamping rib located outside the body.

[0012] By adopting the above technical solution, since the clamping rib part extends to the outside of the main body, it is easy to determine the connection position during installation and quickly connect and fix it, making installation more convenient. The face cover is arranged into multiple clamping structures according to different areas, which can also facilitate the inspection and replacement of the face cover without disassembling the entire face cover. The clamping rib part is located in the main body, which is easy to process and can make the connection between the clamping rib and the main body more firm.

[0013] In a further embodiment, a portion of the surface of the clamping rib that is partially located outside the main body is located inside the main body.

[0014] By adopting the above technical solution, only part of the circumferential surface of the clamp part outside the body is located inside the body, and part of the surface is located outside the body, which is convenient for quickly determining the connection position during connection, and also convenient for a tighter connection, so that the face cover and the body have a better fit. This solution is suitable for the case where the body material is relatively soft, such as the body is sponge, and the clamp can be connected to the face cover by passing the connector through the sponge during connection.

[0015] In a further embodiment, the entire surface of the clamping rib that is partially located outside the main body is located outside the main body.

[0016] By adopting the above technical solution, the connection is more convenient, the main body material does not need to be damaged, and the assembly difficulty is lower.

[0017] In a further embodiment, a pit is further provided in the groove, and the retaining rib partially located outside the main body is located in the pit.

[0018] By adopting the above technical solution, a pit is provided in the groove, which can hide the face cover connection part, and the pit can expose the clip embedded in the body so as to connect and fix with the face cover. The pit can provide a space for placing connecting parts such as the clip spring, and reduce the protrusion of the clip spring after connection to affect the appearance.

[0019] In a second aspect, the present application provides a backrest, comprising the face cover snap-on structure as described in the first aspect.

[0020] In a further solution, the backrest includes a headrest, and the clamping rib is arranged at the edge of the headrest.

[0021] By adopting the above technical solution, it is more convenient and quick to install the cover on the backrest, and the overall appearance is good. Because the headrest usually protrudes from the backrest, the clamp is set at the edge of the headrest. When connecting, the cover can fit the headrest better and better reflect the curve of the headrest, which can make the connection more reliable and reflect the overall curve of the backrest.

[0022] In a third aspect, the present application provides a seat comprising the face cover snap-on structure as described in the first aspect.

[0023] The seat adopting the surface cover clip-on structure described in the first aspect has a simple structure, beautiful appearance, high production efficiency, can be applied to various complex shapes, and has higher design and processing flexibility.

[0046] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0047] Embodiment 1

[0048] See also Figure 1 and Figure 2The present embodiment discloses a backrest including a cover 2 and a seat back 1, wherein the seat back 1 includes a headrest 12, a cover clip structure is arranged at the edge of the headrest 12, a plurality of clip ribs 3 are connected at intervals at the edge of the headrest 12 of the seat back 1, and the cover 2 is connected and fixed to the clip ribs 3.

[0049] See also Figure 2 The distance between the points where the cover 2 and the clamp 3 are connected is generally between 80 and 150 mm. Simple shapes will be evenly arranged and the spacing will be as large as possible to save costs. Complex shapes will reduce the spacing to achieve a satisfactory appearance.

[0050] See also Figure 2 and Figure 3 A groove 11 is arranged around the edge of the headrest 12 of the chair back 1, and a clip 3 is arranged in the groove 11. A plurality of pits 111 are arranged in the groove 11, and the clip 3 located in the pit 111 is partially exposed from the chair back 1. The clip 3 of this embodiment is a ring-shaped metal wire, and it is best to use a magnetic iron wire or steel wire. The material of the part where the chair back 1 is connected to the clip 3 is sponge. The clip 3 is placed in a sponge foaming mold and is integrally formed with the chair back 1. The clip 3 located in the pit 111 and exposed from the chair back 1 is used for fixed connection with the face cover 2, and the rest of the clip 3 is buried in the sponge to fix the clip 3 and the chair back 1, thereby increasing the connection reliability.

[0051] See also Figure 3 and Figure 4 , the face cover 2 is provided with a clip strip 4, and the clip strip 4 and the clip rib 3 are connected and fixed by a connecting piece. The chair back 1 is provided with a groove 11, and the clip rib 3 is arranged in the groove 11. The clip rib 3 is partially located inside the chair back 1, and partially located outside the chair back 1, and the clip strip 4 of the face cover 2 is connected and fixed to the clip rib 3 located outside the chair back 1. In another embodiment, part of the surface of the clip rib 3 located outside the chair back 1 is located inside the chair back 1, that is, part of the outer peripheral surface of the clip rib 3 is buried in the chair back 1, and part is exposed from the chair back 1 and can be observed, which is faster and more accurate during assembly.

[0052] See also Figure 5 and Figure 6 A pit 111 is formed on the bottom surface of the groove 11 . The pit 111 has a depth which is designed to be in the range of 1 mm to 10 mm as required. Most of the circumferential surface of the clamping rib 3 is located inside the chair back 1 , and only part of the surface is exposed on the bottom surface of the pit 111 .

[0053] The processing technology of the clip 3 and the chair back 1 is as follows: the clip 3 is placed in a molding mold, and since the clip 3 is magnetically conductive, a magnet is provided in the mold, and the magnet magnetically fixes the clip 3, and the sponge is filled into the mold cavity and foamed by compression molding or injection molding, and the clip 3 is covered and fixed as a whole, and a part of the area is exposed on the surface of the chair back 1. The clip 3 located in the pit 111 is the area for magnetic fixation, so a part of the clip 3 must be exposed on the chair back 1 to be fixed by the magnet.

[0054] This solution is that when the cover 2 is connected, the entire circumference of the clamp 3 in the pit 111 needs to be separated from the sponge of the seat back 1, so that the cover 2 can be fixed between the clamp 3 and the seat back 1. The advantage of this connection method is that the connection between the cover 2 and the seat back 1 is tighter, but the disadvantage is that the operation is relatively cumbersome, and the part of the sponge connecting the seat back 1 and the clamp 3 needs to be destroyed during the installation process. If an operating tool such as a clamp is used, this disadvantage will not affect the assembly efficiency.

[0055] Embodiment 2

[0056] See also Figure 7 This embodiment discloses another implementation scheme, which is different from the first embodiment in that the entire surface of the clip 3 located outside the chair back 1 is exposed outside the chair back 1. A pit 111 is provided in the groove 11, and the clip 3 located outside the chair back 1 is located in the pit 111, and the remaining part of the clip 3 is buried in the chair back 1. The clip 3 in the pit 111 is completely exposed and higher than the bottom surface of the pit 111 of the chair back 1, which is convenient for assembly and connection. The pit 111 is an area recessed in the groove 11, so the bottom surface of the pit 111 is lower than the bottom surface of the groove 11. Even if the clip 3 is completely exposed from the bottom surface of the pit 111, it can be located in the groove 11, and will not be too protruding and affect the appearance. The shape of the clip 3 located in the pit 111 can be semicircular, semi-rectangular, circular, etc., and a gap is left between the clip 3 and the bottom surface of the pit 111, which is convenient for connection and fixation with the face cover 2.

[0057] Embodiment 3

[0058] See also Figure 8 and Fig. 9 , which is different from the first and second embodiments, in this embodiment, the clip strip 4 on the face cover 2 and the clip rib 3 in the backrest 1 are connected and fixed by the clip spring 5. Taking the technical solution of the first embodiment in which the clip rib 3 in the pit 111 is partially buried in the backrest 1 as an example, the clip spring 5 passes through the sponge around the clip rib 3 and surrounds and fixes the clip rib 3 and the clip strip 4. During the installation process, a special clip is required to pass the clip spring 5 through the backrest 1 to fix the clip strip 4 on the clip rib 3.

[0059] The installation of the technical solution of the clamping rib 3 of the second embodiment is relatively simple, because the clamping rib 3 in the pit 111 protrudes from the bottom surface of the pit 111 and there is a gap with the bottom surface of the pit 111, so the clamping strip 4 and the clamping rib 3 can be tied and fixed by a thin rope, or a buckle can be provided on the clamping strip 4 to buckle on the clamping rib 3, or a hook can be provided on the clamping strip 4 to hook the clamping rib 3 for connection.

[0060] Embodiment 4

[0061] See also Fig.10 The present embodiment discloses a seat, specifically a sofa seat, including a seat cushion 7 and the chair back 1 in the first embodiment. According to design requirements, armrests 6 can also be installed on both sides of the sofa seat, and the cover clip-on structure can also be set on the armrests 6 and the seat cushion 7. The chair back 1, the seat cushion 7 and the armrest 6 can respectively make corresponding cover 2 and be connected and fixed with the chair back 1, the seat cushion 7 or the armrest 6 through the cover clip-on structure.

[0062] In specific practice, the backrest 1, the seat cushion 7 and the armrest 6 can all be provided with the clamping ribs 3, and then the corresponding cover 2 can be made for the backrest 1, the seat cushion 7 and the armrest 6, and the cover 2 and the backrest 1, the seat cushion 7 and the armrest 6 can be connected and fixed by the cover clamping structure, and then the three can be assembled and fixed into a sofa seat. The backrest 1, the seat cushion 7 and the armrest 6 can also be provided with the clamping ribs 3, and the backrest 1, the seat cushion 7 and the armrest 6 can be installed and fixed into a sofa seat, and then a complete cover 2 can be made for the entire sofa seat, and fixed to the surface of the sofa seat by the cover clamping structure, so that the overall aesthetics of the sofa seat is better from the appearance.
