Patent ID: 8870970

Claim:
A dynamic support apparatus for use with a prosthetic device comprising: a multi-piece frame having a first piece and a second piece connected by a plurality of straps, the first piece having an inner surface and an outer surface; a prosthetic mount connected to the outer surface of the first piece, the prosthetic mount adapted to connect a prosthetic device thereto; a dynamic interface, capable of changing its geometry, disposed on the inner surface of the first piece, the dynamic interface having at least one actuator; and a control system operably connected to the dynamic interface by at least one connector, the control system having a plurality of user selectable control modes, each user selectable control mode defining a different geometry change of the dynamic interface to provide a different fit for the dynamic support apparatus; wherein the plurality of user selectable control modes includes a resting mode, a light load mode and a high load mode; and wherein the geometry change of the dynamic interface in the high load mode is greater than the geometry change of the dynamic interface in the light load mode, which is greater than the geometry change in the resting mode.
