Abstract

Un capuchon supérieur et un boîtier coopèrent pour créer un vide interne où sont situés deux ressorts en élastomère, l'un sur le dessus de l'autre. Deux différents systèmes d'arrêt robustes sont incorporés dans le capuchon et le boîtier. Un système de couplage fixe solidement de façon amovible le capuchon et le boîtier afin de pouvoir soumettre les deux ressorts en élastomère thermoplastique à une précharge. Les ressorts sont conçus et logés de façon à plier et à fléchir au lieu de se comprimer pendant un cycle de hauteur sans charge à hauteur sous charge.
