Embodiment Construction

[0075] figure 2is a perspective view of a flexible fastener strip 2 comprising a base 4 and parallel rows 6 of opposing discrete fastener elements 8 extending from the base 4 and Holding channels 10 are defined between the rows 6 . Discrete fastener elements 8 each include a stem 12 and a head 14 . The base 4 and row 6 of discrete fastener elements 8 may be integrally formed from a seamless body of resin. Alternatively, discrete fastener elements 8 may be molded onto prefabricated substrate 4 .

[0076] The heads 14 of the discrete fastener elements 8 extend inwardly toward the center of the retention channel 10 to define an overhang at the top of the retention channel 10 . The fastener elements 8 may be generally aligned across the retention channel 10, or may be partially offset.

[0077] Discrete fastener elements 8 are closely spaced within row 6 . For example, discrete fastener elements 8 may be minimally spaced to provide sufficient clearance to allow independent mo...

Abstract

A releasable touch fastening device includes a fastener strip (2) and a retaining rib (20). The fastener strip includes two parallel rows (6) of adjacently opposed fastener elements (8) extending from a common base (4) to form a retention channel (10). The two rows are spaced a small distance apart to receive and capture retention beads configured to fit between the rows of fasteners and under the heads (14) of the fastener elements.

Description

technical field [0001] The present invention relates to releasable fastening means along beads, and more particularly to such fastening means in anchoring fabric panels to supporting foam structures. Background technique [0002] Furniture, car seat covers, and other upholstery applications have long employed looping, stitching, or fasteners to secure the edges or seams of upholstery or other fabric panels to underlying structures, such as seats or furniture frames. [0003] Seats for cars and light trucks are molded from blocks of foam used as seat cushions. The pre-sewn fabric cover is then attached to the foam block. Typically, the fabric cover is attached to the foam bun by insert molding touch fastener strips into the outer surface of the foam bun and attaching cooperating touch fastener products to the inner surface of the fabric cover. A mating portion of a detachable fastener is attached to the seat cover to provide a releasable attachment to the foam block. [00...
