ABSTRACT:
An inflatable protective system provides cushioning and containment of an occupant of a vehicle from side impact of the vehicle by another object. The system includes an inflatable bag which is foldabble into a collapsed, relatively compact configuration for placement within a door of a vehicle. An inflator and an impact sensor are also mounted within the door, with the inflator being in flow communication with the bag. Upon impact of the door, the sensor activates the inflator to inflate the bag. The inflated bag forms a substantially broad, planar air cushion having dimensions sufficient to extend over the window opening in the door. The inflated bag forms a shock absorbing cushion that prevents the occupant's head from striking the door elements and also acts as a cushioning barrier to restrain the occupant's head from being ejected through the window opening.
