PROSTHETIC FOOT

摘要

A prosthetic foot with a structural component having a proximal attachment member for fastening the prosthetic foot to a below-knee tube, a below-knee shaft or a prosthetic knee joint, with a forefoot portion secured or formed on the structural component, and with a heel-side spring-damper system which is assigned to the structural component and which is compressed at a heel strike and bears on a sole-side guide element. The structural component is designed as a leaf spring which extends in a posterior direction from the proximal attachment means, and forms an arch and is guided in an anterior and distal direction, wherein the arch protrudes posteriorly beyond the guide element.

1. A prosthetic foot comprising:
a structural component having a proximal connection member to fasten the prosthetic foot to a below knee tube, a below knee shank or a prosthetic knee joint; a forefoot portion connected to the structural component; a heel-side spring-damper system coupled to the structural component, the spring-damper system being compressed at a heel strike during operation of the prosthetic foot and supporting itself on a sole-side guide element; wherein the structural component is embodied as a leaf spring, which extends from the proximal connection member in a posterior direction, forms an arc and is guided in the anterior and distal directions, with the arc projecting beyond the guide element in the posterior direction.
