20 Claims

1. A prosthetic device for a lower extremity, comprising a prosthetic knee joint having an upper part, on which a proximal prosthetic component is arranged, a lower part, which is connected to the upper part so to be pivotable about a knee joint axis, and a distal prosthetic component, on which a prosthetic foot is formed or can be secured, characterized in that the distal prosthetic component is mounted so as to be linearly and longitudinally displaceable in the direction of the knee joint axis by means of an axial force acting in the longitudinal extent of the distal prosthetic component, and the knee joint is assigned a force transmission device which, in the stance phase, converts the linear and longitudinal displacement of the distal prosthetic component in the direction of the knee joint axis into a flexion moment about the knee joint axis.
