Abstract
A polycentric variable axis pivotal hinge system especially designed and adaptable to follow the complex movement of the knee when incorporated in orthotic devices, having an upper and a lower extension overlying a central linking member and pivotally connected thereto wherein each extension moves in a relative angular motion determined by the coaction of a guide pin follower slidably and pivotally interacting with slots in the angular terminal portions of the extensions and the guide pin follower moving in a vertical slot in the central member; with provision for motion limiting stops.
