Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0028] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0029] 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 the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0030] like Figure 1-Figure 4 As shown, a self-contained double piping strip structure for a car seat mainly includes: a first piece 1 and a second piece 2. In this embodiment, the first piece 1 and the second piece 2 are both flexible parts. When a passenger touches the first piece 1 or the second piece 2, the flexible parts can ensure good comfort without the foreign body feeling of rigid parts.
[0031] Among them, the first panel 1 has a first edge on one side close to the second panel 2, and the second panel 2 has a second edge on one side close to the first panel 1; the first edge and the second edge are both folded in half and sewn together, and a first piping strip 10 is formed on the first edge, and a second piping strip 20 is formed on the second edge, and the first piping strip 10 and the second piping strip 20 at least partially protrude from the first panel 1 and the second panel 2, which can increase the fuller three-dimensional sense. Specifically, in this embodiment, the height of the first piping strip 10 and the second piping strip 20 protruding from the first panel 1 and the second panel 2 is 3 to 5 mm, which ensures that the first panel 1 and the second panel 2 have a protruding sense and a beautiful appearance, while minimizing the impact on the comfort of passengers.
[0032] It should be explained that the first piping strip 10 is formed on the first edge of the first panel 1, and the second piping strip 20 is formed on the second edge of the second panel 2, which means that the first piping strip 10 is a part of the first panel 1 itself, and the second piping strip 20 is a part of the second panel 2 itself, and no additional piping strip components are required, that is, the entire double piping strip structure only includes the first panel 1 and the second panel 2, and the number of components required as a whole is small, which can effectively reduce material costs. In addition, the first piping strip 10 and the second piping strip 20 formed by themselves can adjust their protruding sizes arbitrarily, and the design freedom is high.
[0033] Specifically, combined Figure 1 and Figure 3 As shown, in the actual forming process, the first edge and the second edge are first sewed to form a first sewed seam 121 (see Figure 1 The two are then folded in half and sewed together to form a second suture seam 122 (see Figure 3 As shown in FIG. 1 ). The first piping strip 10 and the second piping strip 20 can be formed by sewing twice, the process is simple, and no gluing or other operations are required during the formation process. In addition, the rubber strip in the traditional piping strip is eliminated, which can prevent the rubber strip from pressing against the passenger and causing a foreign body sensation. The double piping structure of this embodiment can improve the comfort of the passenger.
[0034] The first suture seam 121 is located above the second suture seam 122, and the distance between the first suture seam 121 and the second suture seam 122 is 2-6 mm, which can ensure both the suture quality and the convenience of suture.
[0035] Preferably, the distance between the end edge of the first panel 1 close to the first suture seam 121 and the first suture seam 121, and the distance between the end edge of the second panel 2 close to the first suture seam 121 and the first suture seam 121 are 7 mm to 9 mm. The specific value of the distance can be selected according to the actual needs of the user.
[0036] In actual use, the user can adjust the protruding height of the first edge strip 10 and the second edge strip 20 by adjusting the folding height of the first edge and the second edge. In addition, the user can choose different colors of the first panel 1 and the second panel 2 and the color of the stitching line according to actual needs, thereby achieving different visual effects.
[0037] In this embodiment, after the first panel 1 and the second panel 2 are sewn together, the first panel 1 forms a first piping strip 10 on its first edge, and the second panel 2 forms a second piping strip 20 on its second edge. No additional piping strip components are required, and the whole includes the first panel 1 and the second panel 2. The overall structure is simple, the number of components is small, and the cost of raw materials can be saved. In addition, the user can adjust the protruding height, size, color and other parameters of the first piping strip 10 and the second piping strip 20 according to actual needs, with high design freedom, and the rubber strip structure is eliminated, ensuring that passengers do not feel foreign objects after contact, which can improve the comfort of passengers.
