Abstract (en)

[origin: EP1235047A2] Pyrotechnic igniter comprises an ignition bridge (1) with a reactive layer made from a combustible metal (6) or a metal which releases energy on alloying with the metal (7) of the bridge. An Independent claim is also included for a process for the production of a pyrotechnic igniter by pressing a resin containing a metal onto a metal base, allowing the resin to dry, and sintering to form a layer composite. Preferred Features: The reactive layer is applied as a score or in the form of islands. A thin electrically insulating layer e.g. made from an oxide or nitride of the reactive layer, is between the ignition bridge and the reactive layer. The combustible metal is zirconium, or titanium, hafnium, niobium, tantalum, aluminum or nickel.
