An elbow fitting part for upper arm stumps includes an elbow ball connected by a hinged axle to the lower arm, configured as a hollow synthetic part, and is detainable by a latch-locking device in various bending positions, while the proximal connection to the upper arm shaft is created by a cast-in ring and an upper arm rotating joint is provided for the adjustable rotation of the lower arm. In order to make this elbow fitting part usable for all upper arm stump lengths, the upper arm rotating joint is configured as an annular bearing and the latch-locking device is a traction lock which is disposed outside the elbow ball and is integrated into a rotating connection forming a section of the hinged axle.

L'invention porte sur un raccord coude, pour un moignon du bras supérieur, comprenant une articulation à rotule reliée à l'avant-bras par un axe à charnière, conçue comme une pièce synthétique creuse et pouvant être retenue dans différentes positions de pliage par un dispositif de verrouillage. Toutefois, la connexion proximale à l'arbre du bras supérieur est obtenue au moyen d'une bague intégrée, et un joint à rotation pour bras supérieur est prévu en vue de régler la rotation de l'avant-bras. Afin que ce raccord coude puisse servir pour toutes les longueurs de moignons du bras supérieur, le joint à rotation de ce dernier est conçu comme un coussinet annulaire. En outre, le dispositif de verrouillage, qui constitue un verrou de traction, est monté à l'extérieur de l'articulation à rotule et est intégré à une connexion rotative formant une section de l'axe à charnière.
