Collision air bag and flotation system
First Claim
1. A pre-impact inflation air bag system for a vehicle having a preselected decreasing distance between the vehicle and an object, comprising:
- a plurality of nested inflatable air bags;
an enclosure located on the vehicle for containing said plurality of nested inflatable air bags;
a plurality of inflators for inflating said plurality of nested inflatable air bags, respectively;
a collision sensor for producing a collision sensor output upon detecting the object with the preselected decreasing distance between the vehicle and the object;
a controller receiving said collision sensor output for simultaneously inflating each of said plurality of nested inflatable air bags between vehicle and an object; and
a plurality of pressure relief members connected to said plurality of nested inflatable air bags for sequentially deflating said plurality of nested inflatable air bags upon sequential impact of said plurality of nested inflatable air bags with the object.

Abstract
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.

18. A pre-impact inflation air bag system for a vehicle having a preselected decreasing distance between the vehicle and an object, comprising:
-
a plurality of nested inflatable air bags comprising a first inflatable air bag, a second inflatable airbag and a third inflatable air bag; said plurality of inflatable air bags being disposed in a nested relationship with said second and third inflatable air bags being located within said first inflatable air bag and with said third inflatable air bags being located within said second inflatable air bag; an enclosure located on the vehicle for containing said plurality of nested inflatable air bags; a plurality of inflators comprising a first through fourth inflator for inflating said first through fourth inflatable air bag, respectively; a sensor for producing a sensor output upon detecting the object with the preselected decreasing distance between the vehicle and the object; a controller receiving said sensor output for enabling said first through fourth inflator to individually and simultaneously inflate said first through fourth inflatable air bags, respectively, between vehicle and an object; and a plurality of pressure relief members deflating said plurality of nested inflatable air bags upon impact of each of said plurality of nested inflatable air bags with the object, respectively wherein said first inflatable air bag deflates prior to said second inflatable air bag and said second inflatable air bag deflates prior to said third inflatable air bag. - View Dependent Claims (19, 20, 21)
