ABSTRACT:
A knee hinge with selectively limited motion which optionally limits an available flexion range of a user's knee to approximately 24 degrees so that a user will not fall should the user buckle at the knees. The hinge may be released to provide for a greater range of knee flexion which will allow a user to sit down in a conventional manner. The approximately 24 degree limit of the flexion range is automatically re-engaged when the user's knee is straightened. The hinge provides a spring mechanism for assisting weak knee muscles. The hinge also allows a small degree of knee hyperextension for the purpose of allowing the user to assume and maintain a safe standing position.
