<p>A knee brace comprising upper and lower leg-engaging/embracing parts (thigh and calf pieces) connectable around upper and lower parts of the leg above and below the knee joint with the upper and lower leg embracing parts having upper and lower brace members (18,24) respectively interconnected by at least one joint means, said joint means each comprises at least one link member (22) pivotally connected at pivot points (23,25) to rotate about a pivotal axis on each of said brace members with said at least one link member being provided for holding said brace members together, and wherein the end region of a first said brace member has a slot (20) defined between two end arm portions and within the slot space or forming a defining portion thereof, a first gear means (19) is provided and such is engaged by second gear means (27) on the end of the second brace member which second gear means is displaceable in said slot to engage said first gear means; and wherein said first and second gear means each lie on arcs each concentric with the pivot point of the brace member on which the respective gear means is provided, and with the arc of the normally upper brace member being on a smaller radius than the other so that the upper brace member rotates at a faster angular velocity than the lower brace member to proximate the movement of a knee joint.</p> |
