Abstract

La présente invention concerne une jambe de support de tracteur électrique pour un fauteuil roulant avec un repose-pied. La jambe de support comprend un repose-pied et deux tiges de support, les extrémités supérieures des deux tiges de support étant respectivement utilisées pour être fixées sur deux côtés d'une partie arrière du tracteur électrique du fauteuil roulant ; les deux tiges de support s'étendent vers le bas ; le repose-pied est relié entre les deux tiges de support ; et le repose-pied est positionné au niveau d'une partie inférieure des deux tiges de support pour qu'un utilisateur s'appuie dessus. Au moyen de la présente invention, la jambe de support du tracteur électrique du fauteuil roulant sert également de repose-pied, de telle sorte que le repose-pied d'origine sur le fauteuil roulant est remplacé, et une situation dans laquelle le repose-pied ne peut pas être utilisé en raison du repose-pied d'origine sur le fauteuil roulant interférant avec la ambe de support du tracteur électrique du fauteuil roulant est évitée, améliorant ainsi l'universalité de la jambe de support du tracteur électrique.
