Abstract
A joint-supporting device comprises tensile members extending from above the joint to below it, supplementing the tensile characteristics of the joint's tendons, ligaments, and other structure. The tension members extend between a proximal cuff above the joint to a distal cuff below it, and pass over a pad at the apex of the joint, redirecting the tension members. In order that the cuffs are supported in position so that the tension members can effectively support the joint, they are spaced away from the joint by compression members bearing on proximal and distal bolsters, in turn located positively by the boney structure of the joint.In order that the structure of the invention not interfere overly with the normal function of the joint, the device employs dilatant materials having the property of varying their hardness upon motion. The dilatant material is disposed so as to limit the relative angular velocity of the members of the joint. The dilatant material can be disposed in pad form, arranged to be compressed by the tensile members as the joint is extended, and/or as the core of a composite tensile member, sheathed in a cover woven of high tensile strength filaments or yarns.
