ABSTRACT:
An automobile airbag system for protecting human occupants of an automobile during an accident is provided. An airbag assembly comprises an airbag inflator assembly (45), an airbag (40), and a remote module (41). The remote module (41) includes a capacitor (42) and an integrated circuit (43) for coupling current through a squib (44) to ignite pyrotechnic material (46). The remote module (41) is formed as a plug which connects to the airbag (45) to simplify manufacture. Capacitor (42) provides energy to the squib (44) and switches for forming a conductive path that couples the current through the squib (44). The wiring between the integrated circuit (43) and the squib (44) is less than 3.0 centimeters to reduce electromagnetic radiation pick up.
