Abstract

La présente invention concerne un dispositif de détection de position de mouvement pour détecter la position de mouvement d’un corps mobile allant et venant et ayant un axe d’opération capable d'aller et venir, tandis qu’il est fixé au corps mobile, dans la direction essentiellement orthogonale à la direction de mouvement du corps mobile ; une résistance variable dont la résistance varie selon la position de l’axe d’opération ; et un rail de détection de position s’étendant dans la direction dans laquelle l’axe d’opération va et vient, le rail de détection de position étant incliné par rapport à la direction du mouvement du corps mobile. L’axe d’opération de la résistance variable s’enclenche avec le rail de détection de position et se déplace dans la direction essentiellement orthogonale par rapport à la direction du mouvement du corps mobile lorsque l’axe se déplace le long du rail de détection de position quand le corps mobile se déplace.
