Abstract
A prosthetic device includes an energy storing member, a lever member attached to the energy storing member, a rocking member and an energy transfer line. This line has a first end attached to a front end of the energy storing member and a second end attached to a back end of the lever member. The line has its middle portion attached to the rocking member. The energy storing member is preferably a leaf spring. This combination of elements in the prosthetic device may be a lower leg or foot for use by a below-the-knee amputee to simulate more closely the natural gait of a person while walking or running.
