1. An airbag device comprising:
- an electronic control unit for determining a vehicle collision and outputting a detection signal in response to the vehicle collision;
a passenger seat airbag module including a first inflator for generating gas based on said detection signal from said electronic control unit, a first airbag inflated at a passenger seat side due to the gas from said first inflator and a first case for housing said first inflator and said first airbag;
a driver'"'"'s seat airbag module including a second inflator for generating gas based on said detection signal from said electronic control unit, a second airbag inflated at a driver'"'"'s seat side due to the gas from said second inflator and a second case for housing said second inflator and said second air bag;
at least one power source for supplying electrical power to said electronic control unit, and to said first and second inflators; and
wiring for electrical connection of said electronic control unit and said first and second inflators,wherein said electronic control unit and said passenger seat airbag module are composed as a single unit.
