Abstract:
Systems, methods, and apparatus provide an artificial knee. Such artificial knees may include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to the thigh link, and a compression spring rotatably coupled to the thigh link at a first end and coupled to the shank link at a second end. The compression spring is configured to provide an extension torque between the thigh link and the shank link during a first range of motion of the thigh link and the shank link relative to each other. The compression spring is configured to provide a flexion torque between the thigh link and the shank link during a second range of motion of the thigh link and the shank link relative to each other.

Claim (Index 6):
The artificial knee of  claim 1 , wherein the artificial knee further comprises:\n a follower link, wherein the compression spring is coupled to the shank link at its second end through the follower link such that the thigh link, the shank link, the follower link and the compression spring form a four bar linkage comprising rotary joints, and a constraint configured to constrain the motion of the follower link relative to the shank link during the first and the second ranges of motion of the thigh link and the shank link relative to each other.
