Abstract

DC60 This invention provides a zipper in which the break-off portion of the zipper teeth will not easily separate during the separation of the force applied when the air bladder is inflated and will have an excellent aesthetic appeal. In the zipper (110), in which each zipper tooth (12, 113) with its first and second leg sections (72, 73) which are teeth and protrude from the zipper head (70) are sewn to its zipper strip (16, 17), a V-shaped cut-off section is created at a single point in the area from the stitch (84) on the first stitch (74) of the first leg section (72) to the stitch (85) on the second stitch (75) through the zipper head (70) to create a brittle section (80) with low break resistance. In this way, even with a large transverse tensile force, The action was performed on the zipper (110) until the zipper teeth (12) broke at the fragile part (80), but the broken part of the zipper teeth (12) remained attached to the zipper strip (16, 17). Figure 9.

Claims (6)

OCR 12JS 1. A zipper is made up of the seams (84,85,86) created by sewing the first and second legs (72, 472, 672;73,473, 673) of the zipper teeth (12, 112, 212,312,412,512,612, 13, 113) of the zipper teeth using sewing thread (15) at a number of points along the white direction of the zipper body of the zipper teeth attachment points of each pair of left and right zipper teeth (16, 516,616, 17) and the first and second legs (72,472,672;73,473,473,673) that are serrated and protrude from the zipper teeth head (70, 470). The zipper is characterized by the fact that it consists of a weak point (80) with low breaking strength at only one point. At least the first and second leg sections (72, 472, 672; 73,473, 673) in the section from the seam (84, 86) of the first leg section (72, 472, 673) to the seam (85, 86) of the second leg section (73, 473, 673) through the fin zipper head (70, 470,670). 2. The zippers as specified in Claim 1, which are characterized by the fragility (80) being built into the zipper teeth head (70, 470, 670). 3. The zippers, as specified in Claim 1, are characterized by the fragility (80) being constructed at a single point in the range from the seam (84, 85, 86) to the zipper teeth (70, 470, 670). 4. A zipper, as specified in any of the claims 1 through 3, which is characterized by the zipper teeth (12, 112, 212, 312, 13, 113) being sewn to the zipper tooth attachment where its folded edge is created by folding the attachment side of the zipper strip (16, 17) inward in a U shape, while the zipper teeth (70) of the zipper teeth (12, 112, 212, 312, 13, 113) protrude outward from the folded edge. 5. A zipper, as specified in any of the claims 1 through 3, which is characterized by being attached by a connecting thread (76) to connect a number of adjacent zipper teeth (12, 112, 212, 312, 512, 13, 113) at the first and second legs (72; 73). 6. A zipper as specified in any of the claims 1 through 3, which is characterized by a number of zipper teeth (412, 612) that are either coiled or in a continuous zigzag pattern (412, 612), where the ends of the first and second legs (472, 672, 473, 673) are connected by a return link on each leg (476, 676).
