Abstract

L'invention concerne un dispositif de tampon de type auto-bloquant comprenant des chambres d'air de type tube disposées au moins en trois rangées parallèles, une paroi de séparation séparant lesdites chambres. Un clapet de non-retour est installé dans chacune des chambres, toutes les chambres d'air étant reliées par l'intermédiaire de passages. Une chambre intermédiaire située entre les chambres d'air disposées sur les côtés opposés de ladite chambre intermédiaire possède une zone transversale plus petite, lorsqu'elle se trouve déployée à l'état normal, que les chambres d'air disposées sur ses côtés opposés. Ladite chambre intermédiaire est comprimée par un contenu, l'air étant évacué vers les chambres d'air et se dilatant dans celles-ci, ce qui permet de réduire l'espace entre lesdites chambres afin de maintenir ledit contenu.
