  • Adapter for self-alignment in 3 dimensional planes for passive prosthetics
    Patent number: 10857008
    Abstract: A self-adjusting adapter for a prosthetic leg having a foot and a leg socket has a low stiffness spring having a central opening, a high stiffness spring that has a central opening and is adjacent the low stiffness spring, a shaft or a bolt passing through the central opening in the low stiffness spring and the central opening in the high stiffness spring and a spring stiffener configured and positioned to restrain movement of the high stiffness spring relative to the low stiffness spring in a direction parallel to the low-stiffness spring. A connector for attaching the adapter to a leg socket is connected to the bolt or shaft and is capable of pivoting about an axis through the bolt or shaft. The adapter can be used an add-on component for existing prosthetic legs, or it can be integrated with foot design for the ankle-foot product category.
