Abstract
(DE)
Es wird eine Beinprothese mit einem Oberschenkelteil (1) und einem Unterschenkelteil (2) und einem die beiden verbindenden Kniegelenk (3), wobei das Kniegelenk (3) ein Dämpfungselement (6) zum Steuern der Kniegelenksbewegung aufweist und mit einer Einrichtung (S1) zum Erfassen des Kniewinkels und einer Einrichtung (S4-S7; S8, S8', S9, S9') zum Erfassen der auf die Prothese wirkenden Kraft und einer Steuerung zum Steuern des Dämpfungselements (6) in Abhängigkeit von Werten für den Kniewinkel und für die Kraft, und mit einer Regelvorrichtung (10), die in Abhängigkeit von erfaßten Werten für den Kniewinkel und die Kraft die Steuerung des Dämpfungselements entsprechend dem Gangverhalten regelt, bereitgestellt.
(EN)
The invention relates to a leg prosthesis, comprising the following: a thigh part (1), a lower-leg part (2) and a knee-joint (3) connecting the two, said knee-joint (3) having a damping element (6) for controlling the movement of the knee joint; a device (S1) for determining the angle of the knee; a device (S4-S7; S8, S8', S9, S9') for determining the force that is exerted on the prosthesis; a control unit for controlling the damping element (6) in dependence on the values for the angle of the knee and the force exerted on the prosthesis; and a regulating device (10) which regulates the control of the damping element in dependence on the values that are detected for the angle of the knee and the force exerted on the prosthesis, in accordance with the walking characteristics.
(FR)
L'invention concerne une prothèse de jambe comportant une partie cuisse (1) et une partie jambe (2) et une articulation de genou (3) reliant les deux. L'articulation de genou (3) présente un élément d'amortissement (6) pour commander le mouvement de l'articulation de genou. Cette prothèse comprend également une unité (S1) servant à déterminer l'angle au niveau du genou, et une unité (S4-S7; S8, S8', S9, S9') pour déterminer la force agissant sur la prothèse, ainsi qu'une unité pour commander l'élément d'amortissement (6) en fonction des valeurs dudit angle et de ladite force. Elle comporte en outre un dispositif de régulation (10) qui régule, en fonction des valeurs détectées dudit angle et de ladite force, le fonctionnement de l'unité de commande de l'élément d'amortissement, selon la façon de marcher.
