Abstract

Cette invention a trait à un dispositif de protection pneumatique comportant un clapet anti-retour à fermeture automatique et au moins deux chambres à air formées, chacune, d'une feuille souple et opposées l'une à l'autre. Une fois qu'un objet est stocké dans un espace existant entre ces chambres à air opposées, elles s'emplissent de gaz, de sorte que l'objet est maintenu appuyé et retenu par le gonflement de ces deux chambres.
