Fastener assembly with mechanical end seals

A fastener assembly adapted for being molded into a foamed structure using a mold having a curved mold recess and curved side walls, said fastener assembly comprising:

• (a) a base having first and second opposed major surfaces, first and second opposed ends, and first and second straight longitudinal side edges;
• (b) a multiplicity of attachment members carried by the base and extending outwardly from the first major surface of the base for mating with complementary attachment members, and said attachment members extending outwardly into the curved mold recess during the molding process;
• (c) first and second spaced-apart end seals attached to respective first and second opposed ends of the base and extending outwardly from said first major surface and into the curved mold recess during the molding process for preventing intrusion of liquid foam past the ends of the base and onto the attachment members during formation of the structure, each of said end seals comprising a solid mass molded onto the first major surface of the base;
• (d) first and second flexible side edge sealing flanges carried by the base and projecting outwardly from the second major surface beyond respective straight side edges of the base;
• (e) the length of said base being sufficiently short and said side edge sealing flanges being sufficiently flexible such that said side edge sealing flanges engage the curved side walls of the mold and form a foam-tight seal between the straight side edges of the base and the mold to prevent intrusion of liquid foam past the straight side edges of the base onto the attachment members during molding of the foamed structure;
• and
• (f) a multiplicity of spaced-apart anchors carried by the base and extending outwardly from the second major surface of the base for permanently attaching the fastener assembly to the foamed structure.
