A second rigid shell of generally hemicylindrical shape rests generally matingly against the front portion of a person's leg slightly below the person's knee, the second shell including a pair of arms extending generally upwardly and rearwardly therefrom, each to a respective one of the positions on opposite sides of the knee. Straps, bands or the like are provided for attaching the first shell above the person's knee and the second shell below the person's knee. A plurality of rigid generally arcuate bars are provided each extending from a respective one to a respective other of the positions on opposite sides of the knee with a central portion of each bar located forward of the knee, the central portions being progressively spaced one from another from the first rigid shell to the second rigid shell. A pair of pivots are provided one at each of the positions, each pivot pivotally connecting a respective arm of the first shell, a respective arm of the second shell and a respective end portion of each of the arcuate bars to pivot thereabout. Also, fabric is provided interconnecting successive arcuate bars to one another, connecting an uppermost one of the arcuate bars to the first rigid shell and connecting a lowermost one of the arcuate bars to the second rigid shell.
