Description

Technical Field

[0001] This utility model relates to the field of seat cover fixing technology, specifically to an invisible suspension structure. Background Technology

[0002] To ensure the seat cover is securely and aesthetically attached to the seat foam, existing seats typically incorporate a suspension structure between the foam and the cover, achieving concealed fastening. Specifically, this structure includes a flexible, non-stretchable suspension component with a suspension groove in the seat foam and a suspension wire embedded within it. During fastening, one end of the suspension component is fixed to the cover, while the other end extends into the suspension groove. A C-shaped pin is then used to connect the suspension component and the suspension wire, effectively securing the cover to the outside of the seat foam.

[0003] To improve the tightening effect, multiple tightening grooves are typically set in the seat foam, and then a corresponding number of hanging holes are set in the tightening component. Multiple C-shaped nails are used to hook onto multiple hooks, thereby making the seat cover more stably tightened. Although setting multiple hanging holes can improve the tightening effect, the tightening components in the existing technology are generally made of non-woven fabric, etc., which can easily tear the hanging holes during use, causing the C-shaped nails to fail. To address this, some tightening structures have a plastic strip fixed to the end of the tightening component connected to the C-shaped nail. The plastic strip is located between the hanging hole and the tightening wire, and it reinforces the end of the tightening component. The aforementioned method of setting a plastic strip at the end of the tightening strip can improve the stability of the connection between the end of the tightening component and the C-shaped nail. However, the stability of the connection between the end of the existing tightening component and the plastic strip is still relatively poor. During use, the plastic strip is prone to detaching from the end of the tightening strip under stress, causing tightening failure. Therefore, it is necessary to further improve the stability of the connection between the tightening strip and the plastic strip, thereby improving the stability of the tightening effect. Utility Model Content

[0004] The present invention aims to provide an invisible suspension structure to solve the problem that the stability of the existing technology is still poor when plastic strips are set in the faceplate suspension structure.

[0005] To solve the above problems, the present invention adopts the following technical solution: an invisible suspension structure, including seat foam and a cover, the seat foam is provided with a suspension groove, a suspension member is connected between the cover and the seat foam, one end of the suspension member is fixedly connected to the cover, the other end of the suspension member is located in the suspension groove and is connected to the seat foam by a connector, a reinforcing plastic strip that cooperates with the connector is fixedly connected to the end of the suspension member located in the suspension groove, and an auxiliary reinforcement part is connected between the suspension member and the reinforcing plastic strip.

[0006] In this application, a suspension member is provided between the seat cover and the seat foam. One end of the suspension member is fixed to the seat cover, and the other end extends into the suspension groove and is connected to the seat foam fixing part through a connector. This allows the suspension member to suspend and fix the seat cover to the outside of the seat foam, thus achieving the suspension of the seat cover. Simultaneously, in this application, a reinforcing plastic strip that mates with the connector is fixedly connected to the end of the suspension member located in the suspension groove. The reinforcing plastic strip connects the end of the suspension member located in the suspension groove into one piece. When the end of the suspension member is connected to the connector, the reinforcing plastic strip allows the entire end of the suspension member to bear the force, preventing excessive force at the connection point between the connector and the suspension member from causing damage, and improving the stability of the suspension member during suspension.

[0007] Meanwhile, in this application, an auxiliary reinforcing part is connected between the suspension member and the reinforcing plastic strip. The auxiliary reinforcing part enhances the stability of the connection between the suspension member and the reinforcing plastic strip. When the suspension member tightens the cover, the connection between the suspension member and the connecting member is more stable, thereby making the cover more stably tightened to the outside of the seat foam.

[0008] Preferably, as an improvement, the clamping member has a reinforcing hole, and the auxiliary reinforcing part includes a reinforcing column fixedly connected to the reinforcing plastic strip, the reinforcing column being inserted into the reinforcing hole.

[0009] In this solution, by opening reinforcing holes on the suspension member, when the reinforcing column fixedly connected to the reinforcing strip is inserted into the reinforcing hole, the reinforcing column and the suspension member are perpendicular to each other. When the suspension member and the connecting member generate relative tension, the reinforcing column can provide better auxiliary support for the suspension member, making the connection between the suspension member and the connecting member more stable.

[0010] Preferably, as an improvement, the cross-section of the reinforcing hole is arc-shaped, triangular, quadrilateral, elliptical, or T-shaped.

[0011] Preferably, as an improvement, the number of reinforcing holes is multiple, and the multiple reinforcing holes are spaced apart along the length direction of the suspension member.

[0012] Preferably, as an improvement, the cross-section of the reinforcing hole is circular, the diameter of the reinforcing hole is greater than or equal to 0.8 mm, and the distance between adjacent reinforcing holes is greater than or equal to 2 mm.

[0013] Preferably, as an improvement, the reinforcing plastic strip is provided with a connecting groove, the end of the hanging member is inserted into the connecting groove, and the reinforcing column is fixedly connected between the two side walls of the connecting groove.

[0014] The shape of the reinforcing holes can be processed according to the actual situation. For example, when the cross-section of the reinforcing hole is semi-circular or circular, it is easy to process and has a good auxiliary reinforcement effect. When it is processed into a T-shape, the reinforcing column has a better auxiliary reinforcement effect on the fastener. At the same time, multiple reinforcing holes are set to make the force between the reinforcing plastic strip and the fastener more uniform, and the fastener is more stable during use.

[0015] When the cross-section of the reinforcing hole is circular, the diameter of the reinforcing hole is greater than or equal to 0.8 mm, and the distance between adjacent reinforcing holes is greater than or equal to 2 mm. This facilitates the molding of the reinforcing column while avoiding an excessively small distance between adjacent reinforcing holes, which could affect the stability of the bottom structure of the fastener. Furthermore, a connecting groove is provided on the reinforcing plastic strip, into which the end of the fastener is inserted, increasing the contact area between the fastener and the reinforcing plastic strip and making the connection more secure.

[0016] Preferably, as an improvement, the connector includes a tensioning wire and a C-shaped nail. The tensioning wire is fixedly connected to the seat foam. One end of the tensioning member located in the tensioning groove is provided with a hanging hole. A reinforcing plastic strip is located between the hanging hole and the tensioning wire. One end of the C-shaped nail is hooked to the tensioning wire, and the other end is hooked to the hanging hole.

[0017] Preferably, as an improvement, the suspension member includes a non-woven fabric and a PWP suspension bar that are fixedly connected to each other, the non-woven fabric is fixed to the face cover, and the PWP suspension bar is connected to the connector.

[0018] Preferably, as an improvement, the PWP tensioning strip, the reinforcing plastic strip, and the reinforcing column are integrally extruded.

[0019] In this solution, the suspension components include non-woven fabric and PWP suspension strips that are fixedly connected to each other. The non-woven fabric is fixedly connected to the strips, and the connection can be made by sewing or other fixing methods, which provides a stable and convenient fixing effect. The PWP suspension strip, the reinforcing plastic strip, and the reinforcing column are integrally extruded and molded, which is convenient to form and the connection between the PWP suspension strip, the reinforcing plastic strip, and the reinforcing column is stable.

[0020] Preferably, as an improvement, the face cover is fixedly connected to the side facing the seat foam with felt fabric, and the non-woven fabric is fixedly connected to the felt fabric.

[0021] In this solution, a felt cloth is fixed between the non-woven fabric and the cover. The felt cloth can provide flexible support for the cover, making the cover look flatter and more beautiful during use. Attached Figure Description

[0026] The following detailed description illustrates the specific implementation method:

[0027] The reference numerals in the accompanying drawings include: seat foam 1, suspension groove 101, cover 2, non-woven fabric 3, PWP suspension strip 4, hanging hole 401, suspension wire 5, C-shaped nail 6, reinforcing plastic strip 7, reinforcing column 8, felt cloth 9.

[0028] Example 1

[0029] This embodiment is as shown in the attached figure. Figure 1 and Figure 2 As shown: A concealed suspension structure includes a seat foam 1 and a cover 2 located on the outside of the seat foam 1. The seat foam 1 has a suspension groove 101. A suspension member connects the cover 2 and the seat foam 1. One end of the suspension member is fixedly connected to the cover 2, and the other end is located within the suspension groove 101. A connector is also connected between the end of the suspension member within the suspension groove 101 and the seat foam 1. In this embodiment, the suspension member includes a non-woven fabric 3 and a PWP suspension strip 4 fixedly connected to each other. The non-woven fabric 3 is fixedly connected to the cover 2 by sewing, and one end of the PWP suspension strip 4 is sewn to the non-woven fabric 3. Of course, in other embodiments besides this one, the non-woven fabric 3 can be replaced with a white polyester strip. Because the white strip is softer, the passenger experiences less discomfort when touching the cover 2 outside the suspension groove 101, making it more comfortable to use.

[0030] like Figure 1 As shown, the connectors in this embodiment include a tensioning wire 5 and a C-shaped nail 6. The tensioning wire 5 is fixedly connected to the seat foam 1 by an integral molding method. One end of the PWP tensioning strip 4 located in the tensioning groove 101 has a hanging hole 401. One end of the C-shaped nail 6 is hooked to the tensioning wire 5 and the other end is hooked to the hanging hole 401. Under the hooking action of the C-shaped nail 6, the PWP tensioning strip 4 and the non-woven fabric 3 suspend the cover 2 on the outside of the seat foam 1.

[0031] To improve the stability of the connection between the C-shaped nail 6 and the end hook of the PWP tensioning strip 4, in this embodiment, a reinforcing plastic strip 7 is fixedly connected to one end of the PWP tensioning strip 4 located in the tensioning groove 101. The reinforcing plastic strip 7 is arranged along the length of the PWP tensioning strip 4, and an auxiliary reinforcing part is connected between the PWP tensioning strip 4 and the reinforcing plastic strip 7. Specifically, the PWP tensioning strip 4 has a reinforcing hole, and the auxiliary reinforcing part includes a reinforcing post 8 fixedly connected to the reinforcing plastic strip 7. The reinforcing post 8 is inserted into the reinforcing hole to cooperate with the connection. Figure 3 In this embodiment, when setting the reinforcing holes, the cross-section of the reinforcing holes is arc-shaped, triangular, quadrilateral, or T-shaped, preferably circular, and there are multiple reinforcing holes. These multiple reinforcing holes are spaced apart along the length of the PWP. The diameter of the reinforcing holes is greater than or equal to 0.8 mm, the distance between adjacent reinforcing holes is greater than or equal to 2 mm, the diameter is preferably 1.2 mm, and the spacing between adjacent reinforcing holes is preferably 2.5 mm. Furthermore, a connecting groove is integrally formed on the reinforcing plastic strip 7. The end of the PWP suspension strip 4 is inserted into the connecting groove. The PWP suspension strip 4, the reinforcing plastic strip 7, and the reinforcing column 8 are fixedly connected by an integral extrusion molding method, so that the reinforcing column 8 is fixedly connected between the two side walls of the connecting groove and is perpendicular to the PWP suspension strip 4.

[0032] The specific implementation process is as follows:

[0033] Firstly, in manufacturing the suspension components, non-woven fabric 3, reinforcing plastic strip 7, and reinforcing post 8 are extruded using an integrated extrusion molding process. Then, non-woven fabric 3 is sewn and fixed to the PWP (Platelet-Padded Film) and attached to the side of the cover 2 facing the seat foam 1. Finally, C-shaped nails 6 are attached and fixed between the hanging hole 401 of the PWP suspension strip 4 and the suspension wire 5, thus fixing the PWP suspension strip 4 and the suspension wire 5 together. Under the suspension action of the PWP suspension strip 4 and the non-woven fabric 3, the surface is stably and securely suspended and fixed to the outside of the seat foam 1. In this embodiment, because a reinforcing plastic strip 7 is provided and a reinforcing post 8 is provided on the reinforcing plastic strip 7, the reinforcing plastic strip 7, located between the hanging hole 401 and the suspension wire 5, can provide structural reinforcement to the end of the PWP suspension strip 4. The reinforcing post 8 makes the connection between the end of the PWP suspension strip 4 and the reinforcing plastic strip 7 more stable, thereby making the cover 2 more securely suspended to the outside of the seat foam 1.

[0034] Example 2

[0035] The difference between Example 2 and Example 1 is as follows: Figure 4As shown, in this embodiment, a felt cloth 9 is fixedly connected between the cover 2 and the non-woven fabric 3. The felt cloth 9 is bonded to the cover 2 with hot melt adhesive, and the non-woven fabric 3 and the felt cloth 9 are sewn together. In this embodiment, by setting the felt cloth 9 between the non-woven fabric 3 and the cover 2, the felt cloth 9 can provide more stable support for the cover 2, allowing the noodles to be more neatly and tightly suspended on the outside of the seat foam 1.
