Abstract: The invention concerns an artificial leg with an artificial knee and an artificial foot. The artificial leg according to the invention comprises the following features: the artificial knee has a joint body turnable about its turning axis for carrying a femoral stump; with a shaft, the upper end of which engages the joint body, and the lower end of which supports the artificial foot; the artificial foot is connected to the shaft in a telescopically expandable manner; there is provided a conrod drive, comprising a connecting rod, the lower end of which is lead by the shaft in a slideable manner, and engages the artificial foot; the upper end of the connecting rod is articulated to a lever arm, which is in driving connection with the joint body, so that during the bending of the artificial knee the distance between its turning axis and the tip of the artificial foot is reduced.

Abstract: The invention concerns an artificial leg with an artificial knee having, for carrying a femoral stump, a joint body which is rotatable about the joint axis; with a shaft, the upper end of which engages the joint body, and the lower end of which bears an artificial foot; joint body and shaft cooperate in such a way that a rotational movement of the joint body is transferred into a translative movement of the shaft, and that during the bending of the knee joint the distance between its joint axis and the tip of the artificial foot is reduced.
