ABSTRACT:
A shoulder strap assembly combines both stretchable and non-stretchable strap members in such a way that the complete assembly has a carefully restricted ability to stretch in the longitudinal direction. A bottom one of the strap members is totally resilient and provides excellent cushioning but lacks the necessary stiffness and mechanical strength to support a load. An upper strap member has a composite structure, being of non-stretchable and strong material in its two end portions but stretchable in its middle section. These two strap members are combined in a parallel relationship and fastened together at the two ends of the stretchable middle section, as well as at other points along their length. The significance of the invention is that while it provides comfort for the wearer and a solid support of whatever load the wearer is carrying, a limited longitudinal stretchability of the strap assembly greatly minimizes the bouncing action.
