Abstract

Es wird eine pyrotechnische Zündeinrichtung mit integrierter Elektronikbaugruppe vorgestellt, die in einen Pyrotechnikbereich mit einer Zündbrücke (1) und einer pyrotechnischen Wirkmasse (3) sowie einen Elektronikbereich mit der Elektronikbaugruppe unterteilt ist, wobei eine gemeinsame Trägeranordnung (2) für Zündbrücke und Elektronikbaugruppe vorgesehen ist, die im Pyrotechnikbereich teilweise mit einem stoßdämpfenden, elastischen Material (4) überzogen ist, jedoch im Elektronikbereich von einem gegenüber dem stoßdämpfenden Material im Pyrotechnikbereich härteren Material (5) umhüllt ist, so dass diese härtere Umhüllung im Elektronikbereich eine Abtrennung und einen Schutz der Elektronikbaugruppe bewirkt, während die weichere Umhüllung im Pyrotechnikbereich stoßabsorbierend wirkt.It becomes a pyrotechnic ignition device with an integrated electronic assembly presented that in a pyrotechnic area with an ignition bridge (1) and pyrotechnic active mass (3) and an electronics area with the electronics module is divided, with a common carrier arrangement (2) for ignition bridge and electronics module is provided, some of which in the pyrotechnics sector a shock-absorbing, elastic material (4) is covered, but in the electronics area compared to the shock-absorbing material in the pyrotechnics area harder material (5) is encased, so that this harder encapsulation in the electronics area disconnection and protection of the electronic assembly while the softer coating in the pyrotechnics area has a shock-absorbing effect.

Die Trägeranordnung weist vorzugsweise eine Längsform mit der Zündbrücke an einem Ende und davon beabstandet der Elektronikbaugruppe auf dem anderen Ende sowie zusätzlich vorzugsweise Trennstellen zur Abtrennung des Pyrotechnikbereichs von der restlichen Trägeranordnung auf, so dass die von der stoßabsorbierenden Umhüllung nicht aufnehmbaren Kräfte zumindest nicht über die Trägeranordnung zur Elektronikbaugruppe weitergegeben werden.

Figure 00000001
The carrier arrangement preferably has a longitudinal shape with the ignition bridge at one end and spaced therefrom the electronic assembly on the other end, and additionally preferably separation points for separating the pyrotechnic area from the rest of the carrier arrangement, so that the forces which cannot be absorbed by the shock-absorbing sheath are at least not via the carrier arrangement passed on to the electronic assembly.
