The invention is directed to an airbag system and, more particularly, to such a system employed as a rescue or life-saving system to enable a person to survive an avalanche, for example. In a particular embodiment, the invention relates to an airbag system utilized with a backpack to be worn by a skier, snowboarder, hiker, or snowmobiler, for example. Instead of relying upon compressed gas cartridges or cylinders to inflate the airbag(s), the invention inflates the airbag(s) with ambient air only. In a particular embodiment, air is supplied to the airbag by means of a battery-powered electrical motor.
