    • PROBLEM TO BE SOLVED: To provide a zipper preventing easy separation of fractured pieces of teeth when being forcibly opened such as during the inflation of an airbag and having a favorable external appearance. SOLUTION: This zipper 110 has teeth 12 and 113 which are formed with first and second leg parts 72 and 73 forked from an engagement head part 70, and sewn to zipper tapes 16 and 17, and is formed with a fragile portion 80 purposely weakening its fracture strength by forming a V-shaped notched portion at one part within a range from a sewing line 84 in a first sewing part 74 of the first leg part via the engagement head part 70 to a second sewing line 85 in the second sewing part 75. Even if an excessive lateral tensile force is applied to the zipper 110 or the zipper is fractured at the fragile portion 80 of the teeth 12, the fracture piece of the teeth 12 is continuously retained at the zipper tapes 16 and 17.

    • 要解决的问题:提供一种拉链,其防止当强制打开时,例如在气囊充气期间并且具有良好的外观时容易地分离出断裂的碎片。 解决方案:该拉链110具有形成有从接合头部70分叉的第一和第二腿部72和73并且缝合到拉链带16和17的齿12和113,并且形成有脆弱部分80 通过在从第一腿部的第一缝合部分74中的缝合线84经由接合头部70到第二缝合线85中的第二缝合线85的范围内的一部分处形成V形切口部,故意削弱其断裂强度 缝制部件75.即使对拉链110施加过大的横向张力,或者拉链在齿12的脆弱部分80断裂,则齿12的断裂片连续地保持在拉链带16和17处。 版权所有(C)2009,JPO&INPIT
