Jointless artificial foot - has spring-elastic foot insert formed at ring spring conforming to natural outer foot contour

摘要

A flat elliptical ring spring (2) is fitted inside a prosthesis body (1), and in company with the body is firmly connected via a connecting piece (9) to an artificial leg (10). The ring spring is made of a fibre union material, in which fibreglass and carbon fibre are used as reinforcements. The reinforcement is partic. strong in the heel (5) and sole (3) areas, with a simultaneously enlarged cross-section of the ring spring. In this way, in the areas of higher load, the spring constant is enlarged, and the loadability of the areas is enhanced. USE - As an artificial foot.
