<p>An artificial limb having two limb members (12, 14) connected by a joint (16) is provided with rotator members (40), comprising one of the limb members, which are relatively rotatable about an axis (22) extending along the limb. A locking mechanism (24) is provided which is movable from a locking position to a released position. In the locking position, the locking mechanism provides a rigid connection between the two rotator members and thereby prevents rotation. When moved to its released position, the locking mechanism is disengaged from at least one of the rotator members, thereby permitting relative rotation between them. The locking member is disposed on one limb member in the vicinity of the joint and is connected via a coupling member (26) to a fixed connection point (28) on the other limb member. Normal movement of the limb about the joint thereby achieves movement of the locking mechanism between its locking and released positions, via the coupling member, and achieves automatic release and locking of the limb with respect to rotation as the limb is bent and straightened.</p> |
