ABSTRACT:
A stretchable, flexible cargo strap assembly comprises an elongated, stretchable first member having the properties of generating restoring force when stretched from a relaxed condition to a tensioned condition, and an elongated second member having a portion which coextends with at least a portion of the first member. The second member is secured to the first member by a plurality of securing members distributed at two or more longitudinally spaced locations along the coextending portions of the first and second members and intermediate the ends of said members, for substantially inhibiting or limiting relative longitudinal movement of the first and second members at these locations while providing for such movement between these locations. The second member is extendable, by stretching of the assembly, to an extended position in which the end-to-end distance of the second member is at least about 1.2 times the end-to-end distance which the second member exhibits when the assembly is in an unstretched condition, and develops a greater resistance to extension than said first member, but only after extension at least to this extended position.
