ABSTRACT:
The invention is an airbag having two modes of deployment. In the normal mode, with a driver in the normal seated position, the airbag is fully deployed and inflated to attain its full normal reach and provide a cushion for protection of the driver in a collision. In the other mode, when a driver is too close to the airbag at the moment of collision, the airbag will deploy only to a shorter reach and thus protect the too-close driver from being forcibly pushed backwards by the airbag inflating to its full normal reach. In the mode for normal deployment an inner flap covers gas exhausting structure on the rear panel of the airbag to prevent escape of inflation gas from the airbag during inflation. But when a driver is too close to the airbag at the moment of collision the inner flap is held away from the gas exhausting structure, keeping such structure uncovered for escape of inflation gas which would otherwise fully inflate the airbag.
