Abstract

La présente invention concerne une pédale de commande pour véhicule, notamment une pédale de frein, comprenant un élément supérieur (6) et un élément inférieur (9), l'un et/ou l'autre étant constitué(s) de matière plastique, couplés par charnière pour former le bras de la pédale, et un patin de pied (10) situé à une première extrémité du bras, l'extrémité distale du bras étant conçue pour être montée pivotante sur un véhicule, le couplage à charnière entre les deux éléments (6, 9) permettant un mouvement supplémentaire de l'élément inférieur (9) par rapport à l'élément supérieur (6) dans le sens d'exploitation de la pédale, cette pédale comprenant également un moyen de sollicitation (14) conçu pour limiter le mouvement supplémentaire lorsque la force exercée sur le patin de pied est en-dessous d'un seuil prédéterminé, alors que lorsque la force exercée sur le patin de pied est au-dessus d'un seuil prédéterminé, l'élément inférieur (9) vient en contact avec la partie fixe (17) du corps du véhicule.
