Abstract

A weightlifting support belt is constructed of two layers of pliable material, fastened together with stitching along the layer peripheries. First and second straps, each with a D-shaped pull ring at its free end, extend longitudinally from opposite ends of a medial section of the belt. Transverse stitching lines divide the space between the layers into a series of transverse compartments spanning the width of the medial section. Flattened, helical coiled springs are contained in each compartment, acting as a flexure to stiffen the medial section while allowing localized torsional bending and arcuate flexing about axes running longitudinally of the medial section. Tape closure strips are provided on the straps for maintaining the straps in overlying relation to maintain the belt in a wrapping configuration about the lumbar region of an individual. An elastic cover strap, provided with a closure strip at its free end, overlies the outermost strap and D-shaped ring to maintain them against the inside strap.
