Fastener components, and method of making fastener components for securing loop-carrying members are disclosed. The fastener component includes a tubular structure, and a plurality of discrete projections extending from a surface of the tubular structure. Each projection includes a molded stem of resin integral with the surface from which the projection extends, and a loop-engageable head formed at a distal end of the stem to overhang the surface. A majority of the projections are directed away from a common, open longitudinal end of the tubular structure to allow longitudinal overlap of the fastener component with a complementary loop-carrying member received from the longitudinal end, but to resist subsequent removal of the loop-carrying member toward the longitudinal end due to engagement of the projections.

What is claimed is: 1. A fastener component for securing a loop-carrying member, the fastener component comprising: a tubular structure having a joint extending longitudinally along the tubular structure; and a plurality of discrete projections extending from an inner surface of the tubular structure, each projection including a molded stem of resin integral with the inner surface of the tubular structure from which the projection extends, and a loop-engageable head formed at a distal end of the stem to overhang the inner surface, a molded rib extending longitudinally from the inner surface of the tubular structure, wherein a majority of the projections are directed away from a common, open longitudinal end of the tubular structure to allow longitudinal overlap of the fastener component with a complementary loop-carrying member received from the common longitudinal end, but to resist subsequent removal of the loop-carrying member toward the common longitudinal end due to engagement of the projections. 2. The fastener component of claim 1, wherein the tubular structure is configured to be longitudinally bisected by two perpendicular planes intersecting along a center of the tubular structure, with each plane intersecting the tubular structure along two opposite sides of the tubular structure. 3. The fastener component of claim 1, wherein the projections have a maximum height above the inner surface of less than 0.025 inch (0. 635 mm). 4. The fastener component of claim 3, wherein the projections have a maximum height above the inner surface of less than 0.010 inch (0. 254 mm). 5. The fastener component of claim 4, wherein the projections have a maximum height above the inner surface of less than 0.005 inch (0. 127 mm). 6. The fastener component of claim 1, wherein the projections comprise molded hooks that each extend from the inner surface of the tubular structure to a distal tip. 7. The fastener component of claim 6, wherein the distal tip is directed toward the inner surface of the tubular structure, to define a re-entrant crook. 8. The fastener component of claim 7, wherein the tip is spaced from the inner surface of the tubular structure by a distance of between about 0.001 inch to about 0.010 inch (0.0254-0.254 mm). 9. The fastener component of claim 8, wherein the tip is spaced from the inner surface of the tubular structure by a distance of between about 0.003 inch to about 0.006 inch (0.0.0762-0.152 mm). 10. The fastener component of claim 6, wherein a back surface of each projection, directed toward the common, open longitudinal end of the tubular structure forms a ramp, free of loop-engaging features. 11. The fastener component of claim 10, wherein the back surface of the projections defines a ramp angle of greater than about 90 degrees, measured in side view toward the crook of the hook from a point where the stem of the hook raises up from the surface to a point of inflection proximate the distal end of the stem where the stem transitions to from the head to the hook. 12. The fastener component of claim 11, wherein the ramp angle is between about 90degrees and about 120 degrees. 13. The tubular structure of claim 1, wherein the tubular structures comprises a cylinder defining two opposite, open ends. 14. The tubular structure of claim 1, wherein the projections are arranged in rows extending parallel to a longitudinal axis of the tubular structure. 15. The fastener component of claim 1, wherein the projections are arranged in a density of between about 500 to about 2000 hooks/inch2 (77.5-210.0 hooks/cm2). 16. The fastener component of claim 1, wherein the rib is formed of an elastomer. 17. The fastener component of claim 1, wherein the joint comprises an adhesive. 18. The fastener component of claim 17, wherein the adhesive is flexible. 19. The fastener component of claim 1, wherein the tubular structure has more than a single joint extending longitudinally along the tubular structure. 20. The fastener component of claim 1, wherein the joint is contiguous extending longitudinally along the tubular structure. 21. The fastener component of claim 1, wherein the joint comprises a material from which the tubular structure is made. 22. A seat cushion comprising: a seat bun formed of a compliant material defining a seating surface, and containing a fastener component comprising a tubular structure and a plurality of discrete projections extending from a surface of the tubular structure, each projection including a molded stem of resin integral with the surface from which the projection extends, and a loop-engageable head formed at a distal end of the stem to overhang the surface, wherein a majority of the projections are directed away from a common, open longitudinal end of the tubular structure to allow longitudinal overlap of the fastener component with a complementary loop-carrying member received from the longitudinal end, but to resist subsequent removal of the loop-carrying member toward the longitudinal end due to engagement of the projections, with the common, open longitudinal end of the fastener component disposed at an outer surface of the bun; and a seat cover extending across the seating surface of the bun, and including a loop-carrying member inserted into the fastener component to secure the seat cover to the seat bun. 23. The seat cushion of claim 22, wherein the compliant material is a foam. 24. The seat cushion of claim 22, wherein the loop-carrying member extends from an inner surface of the seat cover. 25. The seat cushion of claim 22, wherein the loop-carrying member comprises a cylindrical plug extending from the inner surface of the seat cover. 26. A fastener component for securing a loop-carrying member, the fastener component comprising: a tubular structure having a joint extending longitudinally along of the tubular structure; a plurality of discrete projections extending from a surface of the tubular structure, each projection including a molded stem of resin integral with the surface from which the projection extends, and a loop-engageable head formed at a distal end of the stem to overhang the surface; and a molded rib formed of an elastomer extending longitudinally from the surface of the tubular structure, wherein a majority of the projections are directed away from a common, open longitudinal end of the tubular structure to allow longitudinal overlap of the fastener component with a complementary loop-carrying member received from the longitudinal end, but to resist subsequent removal of the loop-carrying member toward the longitudinal end due to engagement of the projections.
