Abstract
A mechanical knee converts the weight of the wearer to a knee extensor force. A rotatable pulley is supported by the lower leg, and a collar which is attached to the upper leg is connected to the pulley by a link. The link is eccentrically connected to the pulley, and when the user applies weight to the collar, the link rotates the pulley. The extensor force is applied to the collar and the upper leg by a bar which is attached to the leg and which is slidably connected to the pulley by a sleeve.
