Description
Domaine techniqueTechnical area
L'invention concerne un agent générateur de gaz pour une composition génératrice de gaz qui est utilisée dans un système de coussin gonflable (airbag) pour la protection d'un individu soumis à un impact par un véhicule. Ci-après, la composition génératrice de gaz sera plus simplement désignée par le terme de générateur de gaz . The invention relates to a gas generating agent for a gas generating composition which is used in an airbag system for protecting an individual subjected to impact by a vehicle. Hereinafter, the gas generating composition will be more simply referred to as a gas generator.
Technique d'arrière-plan En plus des systèmes de coussins gonflables (airbags) pour la protection des passagers d'une voiture, on a souhaité récemment voir se développer des systèmes de coussins gonflables pour la protection d'individus (piétons et assimilés) soumis à un impact par une voiture. Background technology In addition to airbag (airbag) systems for the protection of passengers in a car, it has recently been desired to develop airbag systems for the protection of individuals (pedestrians and the like) to an impact by a car.
Du fait que le générateur de gaz d'un système de coussin gonflable pour la protection d'un piéton est installé à l'extérieur de l'habitacle à savoir (l'intérieur de la voiture où sont installés les passagers), ce générateur de gaz est aisément soumis aux influences de l'environnement extérieur et notamment à la chaleur provenant en particulier du moteur de la voiture, ce qui exige la mise en oeuvre de contre-mesures palliant ces influences. Since the gas generator of an airbag system for the protection of a pedestrian is installed outside the passenger compartment ie (inside the car where the passengers are installed), this generator of gas is easily subjected to the influences of the external environment and in particular to the heat especially from the engine of the car, which requires the implementation of countermeasures to overcome these influences.
Les revendications du document WO-A n 96/27574 décrivent une composition génératrice de gaz comprenant une association de nitroguanidine et de nitrate d'ammonium stabilisé en phase; cette composition génératrice de gaz est stable à la chaleur et a un point de fusion non inférieur à 100 C. Par ailleurs, dans les exemples, le nitrate d'ammonium présente des transitions de phase à 120 C et 130 C et des changements volumétriques se produisent par suite lorsqu'=il est laissé à ces températures élevées, ce qui empêche la composition génératrice de gaz de conserver sa forme. The claims of WO-A No. 96/27574 disclose a gas generating composition comprising a combination of nitroguanidine and phase stabilized ammonium nitrate; this gas-generating composition is heat-stable and has a melting point of not less than 100 ° C. In addition, in the examples, the ammonium nitrate exhibits phase transitions at 120 ° C. and 130 ° C. and volumetric changes occur. as a result, they are produced at such high temperatures, which prevents the gas-generating composition from maintaining its shape.
Les revendications du document WO-A n 98/04507 décrivent un agent générateur de gaz non acide, stable à la chaleur, comprenant une association de nitroguanidine, de tétrazoles et de triazoles à titre de combustible, avec du nitrate d'ammonium ou du perchlorate d'ammonium stabilisé en phase, à titre d'agent oxydant. Lorsque du nitrate d'ammonium stabilisé en phase est ajouté, cependant, le nitrate d'ammoni_um subit des transitions de phase à 120 C et 130 C et il se produit, en conséquence, des changements volumétriques significatifs lorsqu'il est laissé à ces températures élevées, ce qui empêche la composition génératrice de gaz de conserver sa forme. En outre, les tétrazoles et les triazoles réagissent dès 100 C avec le nitrate d'ammonium stabilisé en phase et se décomposent, générant de l'ammoniac gazeux. Le perchlorate d'ammonium ne convient pas à un usage dans des systèmes de coussin gonflable du fait qu'il produit de grandes quantités de gaz, tels que le chlorure d'hydrogène et le chlore, au cours de la combustion. The claims of WO-A No. 98/04507 disclose a heat-stable, nonacidic gas generating agent comprising a combination of nitroguanidine, tetrazoles and triazoles as a fuel with ammonium nitrate or perchlorate. phase stabilized ammonium as an oxidizing agent. When phase-stabilized ammonium nitrate is added, however, the ammonium nitrate undergoes phase transitions at 120 ° C and 130 ° C, and therefore significant volumetric changes occur when left at these temperatures. high, which prevents the gas generating composition from maintaining its shape. In addition, the tetrazoles and triazoles react at 100 C with phase stabilized ammonium nitrate and decompose, generating ammonia gas. Ammonium perchlorate is not suitable for use in air bag systems because it produces large quantities of gases, such as hydrogen chloride and chlorine, during combustion.
Les revendications du document WO-A n 03/011798 décrivent un agent générateur de gaz stable à la chaleur et cohésif qui comprend un polymère cationique et un polymère anionique, avec en outre un liant. The claims of WO-A No. 03/011798 disclose a heat stable and cohesive gas generating agent which comprises a cationic polymer and an anionic polymer, with further a binder.
Cependant, au niveau des détails, la plage de températures de fonctionnement pour l'agent générateur de gaz est limité à -40 C à 120 C et seuls un essai de stockage de 400 heures à température élevée de 107 C et un essai de choc thermique de 200 cycles à une température de -40 C à 100 C sont effectués dans les exemples. However, in detail, the operating temperature range for the gas generating agent is limited to -40 ° C to 120 ° C and only a 400-hour high temperature storage test of 107 ° C and a thermal shock test 200 cycles at a temperature of -40 C to 100 C are performed in the examples.
La résistance à la chaleur des agents générateurs de gaz selon les inventions des documents précités WO-A n 96/27574, WO-A n 98/04507 et WO-A n 03/011798 est inadéquate lorsque le générateur de gaz est installé à un endroit aisément susceptible d'être soumis aux effets thermiques induits par la voiture, par exemple, à proximité du compartiment moteur. The heat resistance of the gas generating agents according to the inventions of the aforesaid WO-A No. 96/27574, WO-A No. 98/04507 and WO-A No. 03/011798 is inadequate when the gas generator is installed in a a place that can easily be subjected to the thermal effects induced by the car, for example, close to the engine compartment.
