A pre-impact inflation air bag system for a vehicle having a preselected decreasing distance between the vehicle and an object is disclosed. The system comprises a plurality of nested inflatable air bags. A plurality of inflators are provided for inflating the plurality of nested inflatable air bags, respectively. A collision sensor produces a collision sensor output upon detecting the object with the preselected decreasing distance between the vehicle and the object. A controller receives the collision sensor output for simultaneously inflating each of the plurality of nested inflatable air bags between vehicle and an object. A plurality of pressure relief members are connected to the plurality of nested inflatable air bags for sequentially deflating the plurality of nested inflatable air bags upon sequential impact of the plurality of nested inflatable air bags with the object.
