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 9):
An artificial knee configured to be worn by a person, the artificial knee comprising:\n a thigh link configured to move in unison with a thigh of a person; a shank link configured to move in unison with a shank of the person, and configured to be rotatably coupled to the thigh link; a compression spring rotatably coupled to the thigh link at a first end of the compression spring, and rotatably coupled to the shank link at a second end of the compression spring; a follower link coupled to the compression spring and the shank link; and a constraint configured to constrain a motion of the follower link relative to the shank link, wherein when the follower link is moved from a singular point toward the constraint, the constraint blocks the follower link, and the compression spring provides 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, and wherein when the follower link is moved from the singular point away from the constraint, the constraint does not block the motion of the follower link, and flexion and extension of the thigh link relative to the shank link are unimpeded.
