Abstract
A contact sport joint protector for protecting the knee or elbow limb joint comprising a unitary, relatively thick, foam-filled, semi-rigid, resilient, molded plastic pad of generally rectangular compound-curved configuration to conform with the shape of said limb joint. The concave inner surface and the opposed side edges of the pad have opposed hinge grooves extending inwardly from each of the opposed side edges to define a hinge portion adapted to overlie the limb joint to enable bending of the normally straight pad upon bending of the limb joint and return of the pad to its normally straight configuration upon straightening of the limb joint. A backing layer of soft, foam plastic material may be adhered to the inner surface of the plastic pad.
