Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, and emergency air bags employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, billowing, and suction.” (Wikipedia, Inflatables, 1/14/2011)
