Abstract
A bi-stable hook component of a touch fastener can bend into, and remain in, a stable concave position. Another stable position enables initial engagement with a mating component (e.g., a loop component). The concave position applies engagement-enhancing tension to the engaged loops, and in some cases forces end portions of the hooks into close proximity with one another to secure the fastening and to produce a curved touch fastener that, as engaged, can better conform to an underlying curved surface, such as the contour of a wearer's body. Absorbent articles having such a bi-stable fastening system are also disclosed.
