Abstract

Cette invention concerne une poussette dans laquelle chacune des roulettes (10) comprend : un corps fixe (20) qui est fixé à un pied avant (3) ; un corps rotatif (40) relié au corps fixe (20) de manière à pouvoir tourner autour d'un axe de roulette (Ac) par rapport au corps fixe (20) ; une roue (70) qui est supportée de manière rotative par le corps rotatif (40) par l'intermédiaire d'un axe (80) ; et un élément de verrouillage (50) qui est en prise avec la roue (70) et qui limite sélectivement la rotation de la roue (70) par rapport au corps rotatif (40). Les éléments de verrouillage (50) d'une paire des roulettes (10) sont connectés par l'intermédiaire d'un élément de fil (60). Lorsque l'élément de verrouillage (50) d'une roulette (10) se déplace vers une position de verrouillage (P1), l'élément de fil (60) amène l'élément de verrouillage (50) de l'autre roulette (10) à se déplacer vers la position de verrouillage (P1).
