<p>Hinge mechanisms (3, 4) are described for connecting together the portions of a limb protector such as a knee brace which need to rotate relative to one another when the limb is flexed. The portions (1, 2) are fitted either side of a joint such as a knee or elbow. Each hinge mechanism has a base (41) on which is a restricted range swivel arm. One of the support members (1) is pivotally connected to the base (51) and the other is pivotally connected (70) to the swivelling end of the arm which is itself pivoted (61) to the base (41). Such a hinge construction is compact and effective and lends itself well to adjustment to the degree of movement permitted to the wearer of the device, conveniently by means of packing pieces restricting the relative rotational movements about the three pivots (51, 61, 70).</p> |
