Above-knee lower limb prosthesis and a shin component for the prosthesis
First Claim
1. A single-piece fibre-reinforced plastics shin component for an above-knee lower limb prosthesis comprising an elongate resilient energy-storing blade having major surfaces and, in the region of one end of the blade and integrally formed with the blade, at least one pivot support extending away from one of the major surfaces to define a plurality of pivot axes for pivotally connecting the component to an upper prosthesis component, the pivot axes extending transversely and generally parallel to the major surfaces and spaced apart from each other in the longitudinal direction of the blade.

Abstract
A single-piece fibre-reinforced plastics shin component for a lower limb prosthesis for an above-knee amputee has an energy storing blade and, integrally formed therewith, a shin cradle in the form of a channel section which has a pair of pivot supports formed as flanges extending away from one of the major surfaces of the blade. Each flange has a pair of holes defining transverse pivot axes, one of which is a knee axis and the other of which is a pivot axis for mounting the distal end of a knee movement control unit. These holes together define a longitudinal axis which is generally parallel to and to the anterior of the blade. The blade merges smoothly into the channel section and, over a distal end portion, is straight and of constant cross-section to allow the blade to be cut to length to suit the amputee.
