Abstract

L'invention concerne un système et un procédé pour former des matériaux de siège à gradient de densité variable pour un haut différentiel de dureté entre flexions élevée et faible, et plus particulièrement pour former des matériaux en mousse pour sièges de véhicule présentant un gradient de densité variable qui permet d'obtenir un confort plus grand pour une plus large gamme de poids d'occupant, ainsi que l'utilisation de formulations de mousses uniques dans une vaste gamme de types de sièges de véhicule présentant différentes caractéristiques de performance souhaitées.
