Abstract
L'invention concerne une butée en forme de coupe pour limiter un mouvement axial d'une tige de piston dans une extrémité d'un cylindre. Selon l'invention, une course 14 a une paroi 32 définissant un espace généralement cylindrique 34, elle est disposée coaxialement à la tige de piston 20, elle a une extrémité fermée 36 fixée à une partie de la tige de piston s'étendant au-delà de l'extrémité 38 du cylindre 22, et elle a une extrémité ouverte 40 disposée vers le cylindre 22, cette extrémité 40 ayant un diamètre interne suffisant pour permettre à l'extrémité du cylindre de s'étendre dans la coupe, et elle a des fentes 42, 44, 46, 48 qui la traversent le long de lignes droites se trouvant dans un plan perpendiculaire à l'axe; des parties d'un élément d'arrêt 12 peuvent être insérées dans les fentes et s'étendent à travers l'espace interne afin de limiter l'étendue du mouvement du cylindre dans la coupe. L'invention s'applique notamment aux sièges inclinables.
