Abstract

La présente invention concerne un tendeur (10) comprenant une base (20) et un arbre pivot (16) s'étendant depuis la base. Un ressort (18) est connecté bras pivotant (14) afin de solliciter le bras (14) dans un engagement de tension avec un composant d'entraînement sans fin du moteur. Un assemblage antiretour flottant comprend un élément levier (36) et un élément d'engagement de bras (30). L'élément levier (36) est monté tournant sur la base, et l'élément d'engagement de bras (30) est engagé avec l'élément levier. L'élément levier (36) et l'élément d'engagement de bras (30) sont orientés de façon à ce que l'élément d'engagement de bras (30) puisse être sollicité par le ressort (18) en direction de la structure de surface arquée du bras pivotant (14) de façon à appliquer une force de friction qui suffit à arrêter le mouvement du bras (14).
