Abstract

L'invention concerne un dispositif de rupture (10), en particulier pour un gonfleur hybride, comprenant un élément de rupture (20) délimitant un compartiment d'allumeur (25) au moins par parties sur son intérieur (21), dans lequel l'élément de rupture (20), en mode inactif, peut être mis sous pression avec du gaz comprimé sur son extérieur (22) et, lors du fonctionnement, l'élément de rupture (20) peut être détruit par une pression d'éclatement du côté du compartiment d'allumeur. Selon l'invention, le dispositif de rupture (10) comprend un manchon de support (30) agencé dans le compartiment d'allumeur (25) et comprenant une ouverture (32), le manchon de support (30) comprenant une collerette (34) délimitant l'ouverture (33), dans lequel l'élément de rupture (20) s'appuie sur la collerette (34) du manchon de support (30) au moins par parties, suite à la mise sous pression depuis l'extérieur.
