Description

folgende Beschreibung : Kniegelenk mit Exenterfunktion Das Exentergelenk (zum Oberschenkelkunstbein als Kniegelenk) Durch eine andere Anordnung der Drehpunkte, tritt eine Verringerung des Schubmomentes ein, hierdurch findet der abergangzwischen Kniesicherheit und fölliger Freigabe des Kniegelenkes allmählich statt. (Und nicht ruckartig) wie bei den bisherigen Konstruktionen.following description: Knee joint with eccentric function The eccentric joint (to the artificial femur as knee joint) By a different arrangement of the pivot points, If there is a reduction in the thrust torque, the shift takes place in between Knee security and full release of the knee joint gradually take place. (And not jerky) as with the previous designs.

Die Standsicherheit wird bei der Beugestellung erreicht durch die exentrische Anordnung des Drehpunktes B.The stability is achieved by the bending position eccentric arrangement of the pivot point B.

Bei beginn der Beugung, nach ca. 30 Grad, übernimmt der Drehpunkt B. die Führung. Jetzt mlißteDrhpunkt A. um den Drehpunkt B. rotieren.At the beginning of the flexion, after about 30 degrees, the pivot point takes over B. the leadership. Now pivot A. would have to rotate around pivot point B.

Da aber Grehpunkt A. an Drehpunkt D. durch eine Verbindung aus Metall angeschlossen ist, tritt eine Hemmung der weiteren Beugung ein. Wärend bei Gelenken ähnlicner Konstruktionen in diesen Beugewinkel, eine Verschiebung des Oberschenkels gegenüber der Wade möglich ist, tritt bei unserer Konstruktion die oben erwähnte Hemmung ein.But since pivot point A. at pivot point D. by a connection made of metal is connected, there is an inhibition of further flexion. During joints Similar constructions in this flexion angle, a displacement of the thigh against the calf is possible, the above-mentioned occurs in our construction Inhibition.

Inder Schwungfase wird der Fuß vom Kniegelenk aus gesteuert und zwar in einer weise, daß die Fußspitze eine wellenartige Linie im Raume beschreibt und zwar so, daß in dem Augenblick wo die Fußspitze die Senkrechte aus dem Hüftgelenk passiert, die größte Verkürzung eintritt.In the swing phase, the foot is controlled from the knee joint in such a way that the tip of the foot describes a wave-like line in space and in such a way that at the moment when the tip of the foot is perpendicular to the hip joint happens, the greatest shortening occurs.

Bei fölliger Streckung und fölliger Beugung ist der Abstand Knie-Boden gleich groß.With full extension and full flexion, the knee-floor distance is same size.
