Orthotic appliance bracing knee joint, includes jointed proximal and distal limbs, with side sections pivoting about axes at right angles to load-bearing joint axis

摘要

The proximal limbs (161, 162) are connected by a proximal joint (24) and the distal limbs (181, 182) are connected by a distal joint (40). These joints can be turned and fixed. They are scissor joints. Their axes (P, Q) are at right angles to the joint axis about which the load-bearing hinges (12, 14) swing. Parts (341, 342; 361, 362) of the distal side limbs (381, 382) pivot about axes (U1, U2) parallel to the rotation axis (Q). Similarly, parts of the proximal side limbs swing about axes (A1, A2) parallel to the rotation axis (P).
