Patent ID: 7052519

Claim:
A leg prosthesis having a foot pivotally connected to the leg prosthesis at a pivoting joint, said foot and leg prosthesis being relatively pivotally adjustable to facilitate walking on downwardly-angled surfaces comprising: means for step-less adjusting of the foot relative to the leg prosthesis such that, in an adjusted position, the foot is at a fixed angle relative to the leg prosthesis, the means for step-less adjusting comprising: a positioner slidably positionable with respect to the leg prosthesis, said positioner acting against the foot and leg prosthesis to provide the relative pivoting adjustment; and means for slideably positioning the positioner to a fixed position with respect to the leg prosthesis; and means for limiting pivoting movement of the foot relative to the leg prosthesis in the adjusted position during walking, the means for limiting pivoting movement comprising: a resilient element having a first end connected to the foot by an elongate element; and the positioner slidably positions the resilient element to a fixed position with respect to the leg prosthesis such that resilient element spring force resists relative pivoting movement of the foot and leg prosthesis.
