A cover material attachment includes: a base to be installed in a groove of a cushion material; a first support and a second support that are provided upright on the base toward an opening of the groove, and are opposed to each other in a width direction of the groove; a first protrusion and a second protrusion that respectively protrude from the first and second supports in respective directions that bring the first and second protrusions closer to each other, and are to be engaged with an engaging member; and a first frame and a second frame that are provided upright on the base toward the opening of the groove and are opposed to each other in the width direction of the groove. The first and second frames each include a guide configured to guide the engaging member to a space between the first protrusion and the second protrusion.

Cover material attachment

There is provided a manufacturing method of a cover material fastening member including a clip locking member. The clip locking member is integrally provided at an end edge portion of a strip shaped member. The manufacturing method of the cover material fastening member includes: a molding step of filling a resin for forming the clip locking member in a cavity formed on a surface of each of a pair of rolls in rotation; and a press-bonding step of passing the strip shaped member between the pair of rolls in accordance with rotation of the pair of rolls, pressing the resin by the pair of rolls, and continuously press-bonding the clip locking member to two surfaces of the strip shaped member.

Manufacturing method of cover material fastening member and manufacturing apparatus of cover material fastening member

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

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

There is provided a hook-and-loop fastener manufacturing method. Injection molding is performed to form a molded product in which a pillar group and a base plate having a surface from which the pillar group protrudes are integrated into a unified body. A tip part of the pillar group is cut to form a cut product in which a small pillar group shorter than the pillar group and the base plate are integrated into a unified body. A tip part of the small pillar group is melted to form pillar body portions which are non-melted portions and engaging portions which are melted portions and thicker than the pillar body portions from small pillars. The engaging portions are cooled to determine shapes of a plurality of engaging elements including the pillar body portions and the engaging portions.

Hook-and-loop fastener

There is provided a cover-material fixing tool. A cover-material fixing end member is configured to be attached on a cover-material. A clip is configured to be attached on a cover-material fixing end member. The cover-material fixing end member includes a tape member, a clip locking member, and a plurality of stoppers. The clip includes a locking portion for holding the clip locking member to allow the clip locking member to move in a longitudinal direction, and a locking protrusion protruding toward the clip locking member and configured to abut against the stoppers. The clip is movable between the adjacent stoppers to allow position adjustment thereof.

Skin-material fixing tool

A cover attachment structure includes a sheet-shaped cover member, a base, and a fastener member. The fastener member includes a first element row and a second element row. The base has a recessed groove extending along a surface thereof. Fastener elements of the first element row and the second element row are received in the recessed groove and locked in the recessed groove in a state in which engaging head portions of the fastener elements engage with each other. The recessed groove is configured such that a minimum groove width thereof in a width direction orthogonal to a length direction of the recessed groove is less than 2 times a length, in the width direction, of either one of the fastener elements received in the recessed groove.
