Abstract
An artificial leg has a stabilized knee mechanism, that is, a mechanism which resists flexion of the leg when the latter is under load. The leg has upper and lower leg components, for example thigh and shin, and the knee mechanism includes a hollow brake drum with a brake shoe inside it. The drum is connected to the thigh and the shoe to the shin. The shoe frictionally engages the inner surface of the drum to resist flexion of the leg when it is under load.
