2. £s ist bekannt, daß es noch nicht gelungen ist die na tür= liehen Bewegungsabläufe de» &idigr;?&idigr; schlichen Knie-oder Fuß= gelenk* konstruktiv nachzubilden.2. It is known that it has not yet been possible to constructively reproduce the natural movement sequences of the knee or ankle joint.

Mit der rorliAgenden konstruktiven Neugestaltung dieser Gelenke wird e^ne Annäherung an die natürliche Bewegung»= form,insbesondere eine Stabilität des Bewegungsablaufs erreicht.With the ongoing structural redesign of these joints, an approximation to the natural form of movement is achieved, in particular a stability of the movement sequence.

3. Das Grundprinzip des Systems beruht auf 2 gekreust an= geordneten Hebeln.Dadurch gekennzeichnet,daß sie an ihren Endpunkten drehbar gelagert sind und sich an Ihrem Kreu= sungspunkt frei gegeneinander bewegen können.Die hierdurch entstehende 4-Punkt Lastverteilung garantiert bei allen Standardbewegungen des Gelenks einen stabilen Bewegungs= ablauf.3. The basic principle of the system is based on 2 levers arranged in a crossed manner. Characterized by the fact that they are pivotally mounted at their end points and can move freely against each other at their crossing point. The resulting 4-point load distribution guarantees a stable movement sequence for all standard movements of the joint.

FUr die Gestaltung eines Kreuxhebelgelenke in einem eta« bilen System z.B. für ein Prothesen Knie-oder Fußgelenk werden 2 (zwei) oder mehrere Hebelpaare benötigt. Fig.l (Zeichnung Blatt 1 von 3) »eigt die Anordnung der formgleichen Kreuzgelenkhebel (03) in der unteren (01) und oberen (02) Grundplatte.To design a cross-lever joint in a stable system, e.g. for a prosthetic knee or ankle joint, 2 (two) or more pairs of levers are required. Fig. 1 (drawing sheet 1 of 3) shows the arrangement of the identical cross-lever levers (03) in the lower (01) and upper (02) base plate.
