Woven back support belt with rigidity control
First Claim
1. An elongated semi-flexible woven support belt having selective rigidity control, comprising a webbing formed of a plurality of contiguous plies of woven yarns with each ply comprising a plurality of longitudinally extending warp yarns interwoven with a plurality of transversely extending weft yarns, binder yarn means comprising a plurality of longitudinally extending yarns engaging selective weft yarns in the several plies of said webbing and coupling together said plies and any plies therebetween and providing hinge means whereby a longitudinally applied tensile loading on said webbing urges said plies together to increase the rigidity of the webbing, and adjustable means carried by said webbing for applying a selected longitudinal tensile loading on said webbing.

Abstract
A semi-flexible back support belt with selective rigidity control. The belt is formed primarily of a multiple-ply webbing of woven polymeric material. The plies in this webbing are joined together by longitudinally extending binder yarns in a weave pattern which ties together the plies of the webbing in such a manner as to provide a hinging action within the webbing during the application of a longitudinally applied tensile loading on the webbing as provided by the tightening of the belt about the waist of the user which effectively increases the rigidity of the belt. The loosening of a previously tightened belt will decrease the rigidity of the belt. By selectively varying the user applied tensile loading on the webbing, the belt is provided with a wide range of rigidity levels.
