ASPIRATOR AIR BAGS: A SMALL-CAR SOLUTION?

The concept of using an aspirating system for air bag inflation offers some unique functional advantages. The primary one is the ability of the inflator to stall during bag deployment when the bag contacts a fixed body. This provides for self-adjustment of the speed and degree of bag fill, with reduced deployment effects on an out-of-position occupant (often a child). The reduced requirement for primary inflation gas is further help. Sled test data indicate satisfactory injury criteria for the full range of adult dummy sizes up to the 45 mph crash speed range. The system may be capable of providing protection from fatality or serious injury to adult front seat passengers. A child positioned against the system will receive loadings which will be quite sensitive to the vehicle interior, but they can be made tolerable by obtaining low bag deployment. The partial choking of the aspiration also mitigates passenger danger in this circumstance.
