Abstract

The invention relates to medical engineering, in particular to the prosthetics of absent lower limbs. The inventive artificial foot comprises an elastic shape-generating body (1) with a rigid frame (2) arranged therein, a dorsal (3), plantar (4) and calcaneal (5) pneumatic element. Said rigid frame (2) is embodied in such a way that it consists of a boxlike support (6) and a channelled bearing part (13) rigidly connected to each other. The bottom (14) of the bearing part (13) is directed towards the planta, the boxlike support (6) and the channelled bearing part (13) being made of high-strength materials.
