Abstract
The invention relates to a prosthetic foot component comprising a proximal fastening system for securing the prosthetic foot component to a proximal component, a retaining portion situated distally relative to the fastening system and coupled to the latter, an elastic heel element provided on the retaining portion, and a main spring extending in a front-foot region and coupled to the retaining portion, wherein the main spring is mounted in the heel element between a proximal heel component and a distal heel component.
Claims29
A prosthetic foot insert comprising:
- a proximal fastening device for securing the prosthetic foot insert to a proximal component, a holder arranged distally with respect to the proximal fastening device and coupled to the proximal fastening device, an elastic heel element which is arranged on the holder, and a main spring which extends into a forefoot region and is coupled to the holder;
- wherein the main spring is mounted on the elastic heel element between a proximal heel component and a distal heel component;
- the holder has a projection which protrudes in a direction of the forefoot region past the proximal fastening device and which is attached to the main spring;
- the holder is attached to the main spring via an intermediate element;
- the holder and the intermediate element are attached to the main spring at two regions spaced apart from each other in a longitudinal extent of the main spring;
- and
- the intermediate element is fastened to the main spring by a fastener such that the intermediate element remains stationary relative to the main spring, wherein the main spring is coupled to the proximal heel component in a manner not transmitting tensile forces.
