[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figure 1According to the first embodiment of the utility model, the edging strip includes: a fabric base 500, a connecting portion 100 and an edge portion 200; the connecting portion 100 is arranged on the fabric base 500, the fabric base 500 is bent and folded at the connecting portion 100 and formed with a connecting hole 150, and the connecting hole 150 is used to install the core strip; the edge portion 200 is arranged on the fabric base 500, the edge portion 200 is connected to the connecting portion 100 and extends in a direction away from the connecting portion 100, and the edge portion 200 is provided with a reference portion 300, and the reference portion 300 forms a visible outer contour on the surface of the edge portion 200. The connecting portion 100 can be used to connect the core strip, so that the three-dimensional sense and layered sense of the seat can be increased through the core strip, thereby effectively improving the user experience of the seat. Furthermore, since the reference portion 300 forms a visible outer contour on the surface of the edge portion 200, the edging strip can be effectively sewn and connected through the reference portion 300 during the sewing process, thereby ensuring that the connection operation between the edging strip and other parts of the seat can be carried out more smoothly and effectively.

[0030] In certain embodiments, reference Figure 2 The fabric base 500 is bent and folded at the connection part 100 to form mutually overlapping parts, and the overlapping parts of the fabric base 500 are connected by ultrasonic and / or high-frequency welding. The overlapping parts can provide transition points for mutual welding for the fabric base 500, so that the fabric base 500 can be curled and formed by welding, and then the forming effect of the connection hole 150 can be smoothly achieved, so as to form the connection hole 150 and install the core strip.

[0031] It is conceivable that the connection hole 150 can also be formed directly on the fabric base 500 by drilling. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0032] In certain embodiments, reference Figure 4 The fabric base 500 has a first welding position 510 and a second welding position 520. The first welding position 510 is located at the junction of the connecting portion 100 and the edge portion 200, and the second welding position 520 is located at the edge of the edge portion 200 away from the connecting portion 100. The first welding position 510 can directly and accurately shape the curled connecting portion 100, so that the connecting hole 150 can be smoothly formed and the core strip 900 can be wrapped. The second welding position 520 can seal the end of the stacked fabric base 500 to prevent it from loosening and spreading.

[0033] In certain embodiments, reference Figure 4There are multiple first welding positions 510 and they are arranged in a row at the junction of the connecting portion 100 and the edge portion 200. The multiple first welding positions 510 can enable the connecting portion 100 to obtain multiple welding positions in the length direction of the fabric substrate 500, so that the formed connecting portion 100 can be more secure and reliable.

[0034] In certain embodiments, reference Figure 2 The reference portion 300 includes a welding mark 350 formed at the first welding position 510. The welding mark 350 is located at the edge portion 200 and is raised or recessed relative to the edge portion 200. The raised or recessed welding mark 350 can not only provide a visual positioning point for the sewing operation directly, but also provide a staggered and undulating area division effect during the sewing process through the undulating changes between the welding mark 350 and the edge portion 200, thereby ensuring that the sewing operation can be carried out smoothly and stably. The welding mark 350 can block the needle and thread in the sewing operation through its steps, thereby achieving the effect of guiding the direction of the needle and thread, thereby achieving the purpose of improving the accuracy of the sewing operation.

[0035] It is conceivable that the reference portion 300 may also be composed of other components, such as fabrics of different colors and thicknesses that are additionally sewn to the edge portion 200. The specific implementation may be adjusted accordingly according to actual needs and is not limited here.

[0036] In certain embodiments, reference Figure 3 The welding mark 350 is recessed relative to the edge portion 200 and the connecting portion 100, and a step for positioning is formed between the welding mark 350 and the edge portion 200. The strip-shaped and raised welding mark 350 can effectively form a staggered and undulating concave-convex structure on the surface of the edge portion 200, thereby providing a positioning point for the sewing operation. In addition, the strip-shaped welding mark 350 can also linearly guide the outer periphery of the edge portion 200 through its shape, thereby improving the convenience of determining the direction of the sewing operation.

[0037] In certain embodiments, reference Figure 2 , the edge portion 200 is provided with a cutout 400, and the cutout 400 extends from the end of the edge portion 200 toward the connecting portion 100. When the edging strip is bent along the curved contour of the seat, the edging strip will be bent along with it. During the bending process of the edging strip, the edging strip will deform at the cutout 400, and shrink or expand the cutout 400. The existence of the cutout 400 makes the edging strip have a clear deformation point when deformed, and the deformation at the cutout 400 will hardly produce wrinkles, so it can effectively improve the wear resistance of the edging strip and its connecting portion 100, and beautify the overall appearance.

[0038] In certain embodiments, reference Figure 4, the cutout 400 and the second welding position 520 overlap, and the stacked part of the fabric base 500 is welded and connected at the cutout 400. The cutout 400 will make the stacked part of the fabric base 500 in a flush state due to the cutting effect. Therefore, welding the cutout 400 can keep the stacked part of the fabric base 500 flat after welding, thereby facilitating the stacked part of the fabric base 500 to be connected into an integrated structure, and ensuring that the connection hole 150 can stably load the core strip 900.

[0039] In certain embodiments, reference Figure 4 The cutout 400 is zigzag or wavy. The zigzag or wavy cutout 400 has a plurality of avoidance positions for the edge strip to be deformed, so the bending deformation of the edge strip can be effectively guided and wrinkles on the edge of the edge strip can be avoided.

[0040] The second aspect of the present invention provides an embodiment of a seat, including the above-mentioned edging strip. The connecting portion 100 can be used to connect the core strip, so that the three-dimensional sense and layered sense of the seat can be increased through the core strip, thereby effectively improving the user experience of the seat. In addition, since the reference portion 300 forms a visible outer contour on the surface of the edge portion 200, the edging strip can be effectively sewn and connected through the reference portion 300 during the sewing process, thereby ensuring that the connection operation between the edging strip and other parts of the seat can be carried out more smoothly and effectively.

[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
