<p>A prosthetic foot includes an adapter element (30) securable to a residual limb, a foot plate (20) having a heel portion, a toe portion along the length thereof, at least one toe spring (40) connected between the adapter element, the toe portion of the foot plate, a heel spring (50) connected between the adapter element, and the heel portion. The heel spring may be a leaf spring or a tube-type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs (44). Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring, a heel spring extend from the collar to form toe, and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion, and another end of the pylon; and a non-extensible band extends between the heel portion, and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon. At least one toe spring is connected between the collar, and the toe portion of a foot plate. A heel spring is connected between the heel portion of the foot plate, and another end of the pylon.</p> |
