Abstract
An exoprosthesis/orthosis for the human knee-joint comprised of an upper leg part ( ) which can be connected to the human upper leg, and a lower leg part ( ) which can be connected to the human lower leg. Both leg parts ( ) are connected at least via a joint which constructs a joint with two joint axes (M , M ), i.e. a so-called dimeric joint chain, which are connected such that they carry out a forced movement. A polode (movement or rest polode) is assigned to each respective leg part ( ) with regard to the momentary joint axis of said leg parts, whereby curved teeth ( ) are constructed on the upper leg part ( ) and on the lower leg part ( ). The teeth interact similar to sprocket gearing in the movement functional area of the joint ( ), whereby the curved teeth coincide with the polodes (t, f) of both leg parts ( ) in the movement functional area.
