Title
(EN) GAS GENERATOR AND AUTO-IGNITING BOOSTER COMPOSITION
(FR) GENERATEUR DE GAZ ET COMPOSITION PYROTECHNIQUE A AUTO-AMORÇAGE
Abstract
(EN)
The present invention generally relates to auto-ignition/booster compositions for inflators 10 of occupant restraint systems 180, for example. An auto-ignition/booster composition in accordance with the present invention includes an auto-ignition composition 17 combined with silicone. When uncured silicone is added to a mixture of the dry granulated constituents of both the auto-ignition and booster components, an extrudable or thixotropic mixture is produced. The uncured mixture may then be applied to any desired surface 21 within an associated gas generator 10 within a vehicle occupant protection system 180, for example, thereby simplifying gas generator 10 manufacture. A gas generating system 150, 200 incorporating the present composition 17 is also contemplated.
(FR)
La présente invention concerne des compositions pyrotechniques auto-amorçables pour les gonfleurs (10) de systèmes de retenue de passagers (180) notamment. La composition de la présente invention comprend une charge auto-amorçable (17) associée à du silicone. L'adjonction de silicone non vulcanisé au mélange granulaire sec des composants d'auto-amorçage et de gonflement permet la réalisation d'un mélange extrudable ou thyxotrope. Le mélange non vulcanisé peut alors s'appliquer sur toute surface (21) de l'intérieur du générateur de gaz associé (10) dans un système de protection de passagers d'automobile (180), par exemple, ce qui simplifie la fabrication du générateur de gaz. La présente invention concerne un système générateur de gaz (150, 200) intégrant la présente composition (17).
