ABSTRACT:
An airbag restraint system for an automotive vehicle has a first airbag disposed in its folded state in a steering wheel padding and a second airbag disposed in its folded state in a glove box. The first airbag is adapted to be fully inflated upon ignition of a first inflator. The second airbag is adapted to be inflated to some extent upon ignition of a second inflator, and fully inflated upon ignition of a third inflator. The first and second inflators are simultaneously ignited respectively under activations of first and second squibs. Immediately after starting of the ignition of the first and second inflators, an electronic power supply to the first and second squibs is stopped respectively upon breakage of first and second breakable conductor members through which an electric power is suppliable to the first and second squibs. The breakable conductor members are adapted to be broken respectively when the first and second airbags inflate. The third squib is late activated to ignite the third inflator after stopping of the electric power supply to the first and second squibs.
