Abstract

La présente invention a pour objet de réaliser une jambe artificielle qui soit si pratique qu’elle puisse être utilisée immédiatement après la fabrication, un temps d’ajustement après la fabrication n’étant pas nécessaire, qui ait un poids et un coût faibles, évitant qu’une charge physique ne s’applique sur les parties lésées, qui ait une excellente stabilité quand les jambes sont écartées, permettant à un utilisateur de garder facilement son équilibre en marchant, et fournissant à l’utilisateur moins de stress lors d’un pas et pas de sensation d’incongruité quand il court. La constitution de cette jambe artificielle est caractérisée en ce qu’elle comprend une tige de pivot (1) supportant le poids de l’utilisateur le long du côté lésé d’un corps, un levier de support (2) ajusté sur la tige de pivot (1) et utilisé pour maintenir l’équilibre du poids de l’utilisateur en l’agrippant avec une main, et un moyen de montage formé d’un cadre (3), une feuille de harnais (4), une ceinture de taille (5), une ceinture de suspension (6) et une partie de raccordement (7) qui monte la tige de pivot (1) sur le corps de l’utilisateur pour distribuer une charge sur la tige de pivot.
