Abstract

An igniter element and an ignition electronics assembly are mounted and electrically interconnected on a circuit carrier for igniting a pyrotechnic charge, e.g. for deploying an airbag in a motor vehicle. The igniter element (e.g. a layer of ignitable material) is arranged on a carrier body of heat-resistant, thermally insulating material, which is mounted on the circuit carrier. An electrical contact on the carrier body electrically connects the igniter element with the circuit carrier. The carrier body has a standardized configuration, contact arrangement, and dimensions, to be mounted on the circuit carrier like any standardized electronic component using automated equipment. Relative to the contact on the bottom surface, the igniter element can be arranged on a side surface of the carrier body so as to face in a longitudinal direction away from the ignition electronics assembly and toward and into contact with the pyrotechnic charge.
