Abstract
A foot prosthesis having an upper part and a lower part, which is set on the ground as the user walks, one part being arranged on top of the other a certain distance away. The two parts are connected to each other at the tip of the foot. The upper part and the lower part are formed by a one-piece component. In the area near the heel, an elastic damping element is arranged between the upper part and the lower part and is connected to the upper part and/or to the lower part. A compressible but longitudinally strong connecting element, which connects the upper part to the lower part, and which is guided through a recess in the damping element, is provided.
Claims14
A foot prosthesis, comprising:
- a lower part and an upper part defining a top surface and connected to the lower part in a toe area of the foot prosthetic;
- an elastic damping element positioned between the upper part and the lower part in a heel area of the foot prosthetic, the elastic damping element connected to the lower part;
- and
- a cable connecting the upper part to the lower part, the cable being guided through a recess in the damping element;
- and
- a retaining element secured to the cable and engageable with the top surface of the upper part, the retaining element arranged to move along a length of the top surface of the upper part when the upper part is displaced relative to the lower part.
A foot prosthesis, comprising:
- a lower part and an upper part defining a top surface and connected to the lower part in a toe area of the foot prosthetic
- an elastic damping element arranged between the upper part and the lower part in a heel area of the foot prosthetic, the elastic damping element connected to at least one of the upper part and/or to the lower part;
- a connecting part comprising a cable or strap having a compressible but longitudinally strong configuration, the connecting part connecting the upper part and the lower part, and which is and being guided through a through-hole or slot in the damping element;
- and
- a retaining element secured to the connecting part and engageable with the top surface of the upper part, the retaining element arranged to move along a length of the top surface of the upper part when the upper part is displaced relative to the lower part.
