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).

On décrit des mécanismes articulés (3, 4) servant à assembler des parties d'un appareil de protection d'un membre (tel que orthèse pour le genou) devant pivoter les unes par rapport aux autres lorsque le membre est ployé. Lesdites parties (1, 2) peuvent se fixer sur un ou l'autre côté d'une articulation comme le genou ou le coude. Chaque mécanisme articulé comporte un socle (41) sur lequel est monté un bras oscillant de portée limitée. Un des éléments de fixation (51) est monté en articulation sur le socle (41) et l'autre (70) est monté en articulation sur l'extrémité oscillante du bras, lui-même monté en pivot (61) sur le socle (41). Ce montage articulé est compact et efficace et se prête particulièrement à des réglages selon le degré de mouvement autorisé pour le porteur de l'appareil, l'opération pouvant être réalisée sans inconvénient grâce à des pièces de remplissage qui limitent les mouvements rotatoires relatifs autour des trois pivots (51, 61, 70).
