Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a piping strip structure for automobile seats and the automobile seat. Background Art

[0002] The outer surfaces of the seat cushion and backrest of the car seat are covered with covers, which can ensure both aesthetics and comfort.

[0003] Piping strips are often seen at the edges of the seat cushions and backrest side covers. Piping strips are generally set between two adjacent pieces. They are set as decorative edge strips to enhance contour clarity and three-dimensional effect.

[0004] Existing piping strips on car seats are typically a separate trim component. A single layer of fabric is secured with glue to form a long, independent decorative strip. This strip is sewn between two adjacent panels, creating a raised, visible appearance. Existing piping strips are difficult to manufacture and complex, and the strips can easily affect passenger comfort. Furthermore, visible seams and decorative lines are visible, making it difficult to conceal the seams. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a piping strip structure for a car seat that is simple in structure, easy to manufacture, and comfortable, and a car seat.

[0006] The technical solution adopted by the present invention to solve the technical problem is to propose a piping strip structure for a car seat, comprising:

[0007] A first cutting piece and a second cutting piece, wherein the first cutting piece has a first edge on a side close to the second cutting piece, and the second cutting piece has a second edge on a side close to the first cutting piece;

[0008] After the first edge is folded from the first cutting piece, it is sewn to the second edge to form a piping strip at the folded portion. The piping strip protrudes from the first cutting piece and the second cutting piece.

[0009] Furthermore, after the first edge is folded downward from the first panel, it is sewn to the second edge, so that the first edge is sandwiched between the second panel and the first panel.

[0010] Furthermore, the outer side surfaces of the first cutting piece and the second cutting piece are the front side, the inner side surfaces of the first cutting piece and the second cutting piece are the back side, and the binding strip protrudes from the back side.

[0011] Furthermore, the first edge is folded in half and sewn to the second edge to form a sewn seam;

[0012] The front sides of both the first panel and the second panel are provided with visible stitches, and the visible stitches coincide with the sewing seams.

[0013] Furthermore, the distance between the suture seam and the folded portion of the first edge is 3 to 5 mm.

[0014] Furthermore, it further comprises an embedded piece, which is arranged between the first edge and the first cutting piece and is sewn together with the first edge and the first cutting piece;

[0015] The inlay upper portion is configured as a portion of the piping strip.

[0016] Furthermore, the embedded piece is placed on the first cutting piece near the first edge. When the first edge is folded from the first cutting piece, the embedded piece is driven to fold, and the embedded piece is clamped between the first edge and the first cutting piece, and a fillet is formed at the folded part of the embedded piece, and the fillet is configured as a part of the binding strip.

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0033] like Figure 1 As shown, this is an implementation of an existing piping strip structure, wherein the piping strip 120 is a separate component, sewn between the first panel 1 and the second panel 2. No adhesive strip is embedded in the piping strip 120, but of course, an adhesive strip can also be embedded in the piping strip 120. In this structure, a separate piping strip 120 component is required. Example

[0034] like Figure 2 The figure shows a piping strip structure for a car seat according to this embodiment, which mainly includes: a first panel 1 and a second panel 2. The first panel 1 has a first edge 10 on the side close to the second panel 2, and the second panel 2 has a second edge 20 on the side close to the first panel 1. During the manufacturing process, the first edge 10 is folded in half from the first panel 1 and then sewn to the second edge 20, forming a piping strip 120 at the folded portion. The piping strip 120 protrudes from the first panel 1 and the second panel 2. Specifically, the first edge 10 is folded downward from the first panel 1 and then sewn to the second edge 20, so that the first edge 10 is sandwiched between the second panel 2 and the first panel 1. The first panel 1, the first edge 10, and the second panel 2 are then sewn together using sutures.

[0035] In this embodiment, the piping strip 120 can be formed by simply folding the first edge 10 of the first panel 1 in half and sewing it with the second panel 2. No separate piping strip 120 component is required, which has a simple structure and is easy to manufacture.

[0036] The outer sides of the first and second panels 1, 2 are the front sides, while their inner sides are the back sides. The piping strip 120 protrudes from the back sides of both panels, meaning it is reverse-sewn to the back sides (i.e., side B) of the panels, enhancing the aesthetics. The first and second panels 1, 2 are connected by stitching, so after the first edge 10 is folded in half and sewn to the second edge 20, a seam 121 is formed. Preferably, both the first and second panels 1, 2 also have visible stitching on the front sides. This is done by pressing visible stitching on the front sides of the panels, ensuring that the visible stitching overlaps with the seam 121. This conceals the seam 121 (the patchwork line) and further enhances the aesthetics.

[0037] The distance between the sewing seam 121 and the folded portion of the first edge 10 (ie, the edge after the fold) is 3 to 5 mm, and this distance determines the protruding height of the binding strip 120 .

[0038] In this embodiment, after the first edge 10 of the first panel 1 is folded in half from the first panel 1 and sewn to the second edge 20 of the second panel 2, a piping strip 120 can be formed. The piping strip 120 protrudes from both the first panel 1 and the second panel 2. The overall structure is very simple, and there is no need to set up a separate rubber strip. The piping strip structure is simple to manufacture. When the passenger leans against the piping strip 120, there is no foreign body sensation, which can effectively ensure the comfort of the passenger. Example

[0039] like Figure 3 As shown, the piping strip structure of this embodiment, compared to the first embodiment, further includes an inset piece 3 to enhance the fullness and three-dimensional effect of the piping strip 120. Specifically, the piping strip structure of this embodiment further includes an inset piece 3, which is disposed between the first edge 10 and the first panel 1 and sewn to the first edge 10 and the first panel 1. The upper portion of the inset piece 3 is configured as part of the piping strip 120. In other words, a portion of the inset piece 3 functions as part of the piping strip 120, thereby enhancing the fullness and three-dimensional effect of the piping strip 120.

[0040] Specifically, during the manufacturing process, the insert piece 3 is placed on the first panel 1 near the first edge 10. When the first edge 10 is folded in half from the first panel 1, the insert piece 3 is folded in half, sandwiching the insert piece 3 between the first edge 10 and the first panel 1. A welt 30 is formed at the folded portion of the insert piece 3, which is configured as part of the piping strip 120. It should be noted that the insert piece 3 can be pre-sewn to the first panel 1 and then sewn to the second panel 2. Alternatively, the first panel 1, the insert piece 3, and the second panel 2 can be sewn together at once.

[0041] In this embodiment, the height of the binding strip 120 is between 4 and 6 mm, the distance between the seam 121 and the edges of the two panels and the embedded panel 3 is 7 to 9 mm, and the distance between the seam 121 and the edge of the binding strip 120 is 4 to 6 mm.

[0042] In this embodiment, an insert sheet 3 is provided between the first edge 10 and the first panel 1. When the first edge 10 is folded in half, the insert sheet 3 is folded in half and sewn together between the first panel 1 and the first edge 10, forming a fillet 30 on the insert sheet 3. The fillet 30 is filled in the piping strip 120 and serves as part of the piping strip 120, thereby enhancing the full three-dimensional effect. The sewing seam 121 can also be completely concealed.

[0043] When the piping strip structure in Example 1 and Example 2 is applied to a car seat, it is: a car seat, mainly comprising a seat and a backrest arranged on the seat, both the seat and the backrest are provided with a cover, and the cover is provided with the piping strip structure of Example 1 and / or Example 2.
