Title
(EN) GAS-GENERATING MATERIAL FOR GAS-ACTUATED CAR SAFETY DEVICES
(FR) MATIERE LIBERANT DU GAZ POUR DISPOSITIFS DE SECURITE ACTIONNES PAR GAZ POUR AUTOMOBILES
Abstract
(EN)
The present invention relates to a process for the preparation of gas-releasing pyrotechnical compositions that are intended primarily for use in gas-actuated car safety devices such as air-bag assemblies, safety-belt tighteners, inflatable neck supports, etc. and which can be recovered if they are not actively used. The invention also relates to these compositions themselves. The invention is mainly characterized by the use of guanidine dinitramide, possibly combined with guanyl urea dinitramide, as gas-generating substance(s) in products of the said type.
(FR)
Cette invention concerne un procédé de préparation de compositions pyrotechniques à décharge de gaz qui sont destinées principalement à des dispositifs de sécurité actionnés par gaz employés dans des automobiles (coussins d'air, tendeurs pour ceintures de sécurité, appuie-nuque gonflables, notamment) et qui peuvent être récupérés s'ils ne sont pas activement utilisés. L'invention concerne également ces compositions proprement dites. Cette invention se caractérise essentiellement en ce qu'elle fait appel à du guanidine dinitramide, éventuellement combiné à du guanyl urée dinitramide comme agent libérant du gaz pour les produits susmentionnés.
