Air bags are meant to reduce excessive loads acting on occupant’s body during the crash, decreasing injury risk. Used in configuration other than designed they may not provide its proper functionality to the occupant. Untypical position in car (called Out-of-Position) or non-standard occupant (away from a 50-percentile occupant) may cause abnormal operation of the air bag. The developers try to take possible sources of risk into account, adding Out-of-Position to the standard testing procedure and focusing on minimizing its negative influence on airbag functionality.
