Patent

CA 2004768

A top cap and housing cooperate to create an internal void wherein is located two elastomeric springs, one on top of the other. Two different solid stop systems are incorporated into the top and housing. An interlocking system also movably secures the top cap and housing such that the two the thermoplastic elastomeric springs can be subjected to a preload. The thermoplastic elastomeric springs are designed and housed so that through a cycle from free height to solid height they are folded and flexed rather than compressed.

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.
