Abstract

L'invention concerne un dispositif d'allumage pourvu d'un commutateur de sécurité, comprenant un logement, un réservoir d'huile dans le logement, un ensemble piézoélectrique et un ensemble de libération de gaz. Ledit ensemble piézoélectrique comprend un élément piézoélectrique, une détente, et une tige-poussoir supérieure et une tige-poussoir inférieure situées entre la détente et l'élément piézoélectrique. La partie inférieure de ladite tige-poussoir supérieure et la partie supérieure de ladite tige-poussoir inférieure sont connectées de manière à pouvoir être inclinées sur le côté à partir de la ligne centrale de la tige-poussoir supérieure et de la tige-poussoir inférieure. Ainsi, lorsque la détente est activée, la tige-poussoir supérieure et la tige-poussoir inférieure sont inclinées sur le côté au niveau dudit point de connexion. Ledit dispositif d'allumage comprend également un commutateur de sécurité empêchant la tige-poussoir supérieure et la tige-poussoir inférieure de s'incliner.
