A cover-material fixing clip includes: a chuck having a base portion, a first holding piece and a second holding piece; a hook configured to be engaged with a wire to be located in a groove of a cushion material; and an engagement opening defined between the chuck and a leading end of the hook. The base portion, the first holding piece and the second holding piece define a retention groove for holding the held body attached to the cover material. The engagement opening has an opening dimension in a range from 50% to 80% of a width of the retention groove.

Skin material fastening clip

A clip for securing a cover to an opening defined in a base includes a base defining a lower surface and an upper surface distal from the lower surface, the base further defining a cutout extending from the lower surface to the upper surface; a first wall extending from the upper surface of the base of the clip and defining a first latch nail at a distal end of the first wall; and a second wall extending from the upper surface of the base and defining a second latch nail at a distal end of the second wall, the first latch nail and the second latch nail defining a gap therebetween at the distal end of each of the first wall and the second wall, the cutout defined in the base between the first wall and the second wall.

Seat cover fastening clip

There is provided a cover-material fastening end member including a band-shaped member and a locking member. The locking member is formed such that a width thereof in a direction perpendicular to a surface of the band-shaped member is wider than a width of the band-shaped member. The locking member includes: a center plate-shaped portion, a flange portion, and a plurality of rib portions. The flange portion has a surface extending along a longitudinal direction of the end edge portion of the band-shaped member and perpendicular to a surface of the center plate-shaped portion. The rib portions each has a surface intersecting with the center plate-shaped portion and the flange portion. The rib portions are provided on the center plate-shaped portion along the longitudinal direction of the center plate-shaped portion at predetermined intervals.

End member for fastening cover material

A slide fastener in which a fastener element has first and second leg portions continuously disposed at both ends of the coupling head is folded in half at its center, and the first leg portion is attached to a coupling element attaching portion of a fastener tape by a sewing thread. A vulnerable portion which is cut out into a V is formed on the bent end face of the coupling head.

Slide fastener

A slide fastener which withstands a predetermined lateral pulling force in a usual usage and is cloven when an excessive lateral pulling force is applied at the time of airbag inflation, wherein the slide fastener in which a plurality of attachment leg portions of coupling teeth, on each of which a coupling head formed to have a relatively large width and the attachment leg portions extending from the coupling head are formed, are attached on a coupling tooth attaching portion of each of a pair of fastener tapes on right and left with a predetermined pitch along a tape longitudinal direction is configured to satisfy a relationship 0.4&#x2267;(2&#xd7;H&#x2212;P)/P&#x2267;0.1 between a summit height H [mm] of the coupling head formed to have a relatively large width and a pitch P [mm].

A method of forming successive space portion in a slide fastener chain, comprising: positioning the chain in such a manner that an element contiguous to the backward end of a prospective space portion is brought into engagement with a positioning pin upstream of a cutting unit; positioning the chain in such a manner that an element contiguous to the forward end of the prospective space portion is out of engagement with another positioning pin downstream of the cutting unit, and then positioning the chain, as the feed roller is rotated forwardly to extend the chain so that the positioning pin is inserted between the elements, whereupon the downstream positioning pin is brought into engagement with the element adjacent to the prospective space portion as the feed roller is rotated backwardly to restore the slide fastener chain; and cutting off elements of the prospective space portion and removing the cut elements from the prospective space portion.
