Abstract

A slide fastener fastens separated portions of one or more outer material. A pair of fastener tapes includes a pair of main body portions, and a pair of folded portions formed by folding each of opposite inner ends of the pair of main body portions in substantially U-shape. A pair of elements are attached to the pair of folded portions. A slider engages and disengages the pair of elements. The pair of main body portions are sewn to the outer material at positions inner than outer ends of the pair of elements in a width direction of the slide fastener.

Description

technical field [0001] The present invention relates to a slide fastener. In particular, the present invention relates to a slide fastener having a covering tape, which prevents elements from being exposed to the outside and has a good appearance. The present invention also relates to a slide fastener capable of preventing elements from being separated while maintaining a good appearance. Background technique [0002] The seat of the vehicle is covered by an outer sheet along the shape of the urethane resin mounted on the seat frame. In order to easily cover the outer sheet on the polyurethane resin, a zipper may be provided on the backing portion of the outer sheet. There is also a seat in which the outer sheet is detached by using a zipper. [0003] In the outer sheet of such a seat, a concealed zipper can be used or the zipper can be set upside down to visually hide the zipper elements. Therefore, the fastening portion is shaded to provide an exterior sheet with a goo...
