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.

Claims (26)

1. 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.

2. The foot prosthesis of claim 1 , wherein the retaining element comprises a pin.

3. 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.

4. 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; and

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 recess 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.

5. The foot prosthesis according to claim 4 , wherein the connecting part is made of plastic fibers or of steel wire.

6. The foot prosthesis according to claim 4 , wherein the cable or strap forms a loop held in place in by a lower retaining element.

7. The foot prosthesis according to claim 6 , wherein the retaining element is a pin that passes through the loop, the loop extending through an opening in the upper part.

8. The foot prosthesis according to claim 7 , wherein the opening is executed as a slot, which extends along the upper part, or as a hole.

9. The foot prosthesis according to claim 4 , wherein a sleeve is adhesively bonded to the connecting part.

10. The foot prosthesis according to claim 4 , wherein the recess provided in the damping element is a through-hole or slot.

11. The foot prosthesis according to claim 4 , wherein at least one stiffening element is attached to the damping element, the stiffening element arranged to influence a damping effect of the damping element.

12. The foot prosthesis according to claim 11 , wherein a plug-in receptacle is provided in the damping element.

13. The foot prosthesis according to claim 4 , wherein a cover is detachably arranged on the upper part, the cover covering the connecting part along the top surface of the upper part.

14. The foot prosthesis according to claim 4 , wherein the upper part and the lower part comprise a carbon fiber composite material.
