Abstract

L'invention concerne un dispositif d'amorçage prématuré (9) servant à amorcer une charge propulsive d'un générateur de gaz d'airbag destiné à un système de protection des passagers d'un véhicule, sur la base du chauffage localisé du boîtier (1) du générateur de gaz. Ce dispositif comprend un réservoir (10) rempli d'amorce primaire (11), par exemple sous forme de poudre, qui s'enflamme spontanément à des températures inférieures à 400 °C, de préférence entre 150 et 200 °C. Ce réservoir (10) est disposé à l'intérieur du boîtier (1) du générateur de gaz, en étroit contact (12) thermoconducteur avec une partie supérieure (2) du boîtier (1) du générateur de gaz et de façon directement adjacente à un dispositif d'amorçage (7) rempli d'amorce secondaire. Ce dispositif d'amorçage (7), qui peut être amorcé par l'amorce primaire (11), amorce ensuite la charge propulsive du générateur de gaz de l'airbag. L'invention est caractérisée en ce que le réservoir (10) rempli d'amorce primaire (11) est conçu, et disposé à l'intérieur du boîtier(1) du générateur de gaz, de sorte qu'il soit en étroit contact thermoconducteur avec une partie inférieure (3) du boîtier (1) du générateur de gaz opposée à la partie supérieure (2). Il est ainsi possible, avec des coûts de conception minimes, de réduire le temps de réponse entre le début du chauffage localisé du boîtier (1) du générateur de gaz et l'amorçage du dispositif d'amorçage prématuré (9) et d'accroître la probabilité de réponse.
