Abstract and keywords

Injury risk from out-of-position (OOP) side airbag deployment has been assessed using stationary occupant test protocols. However, stationary conditions may not always represent real world OOP scenarios. Therefore, the objective of the present study was to evaluate the effects of OOP torso side airbag deployment, comparing a stationary test protocol with dynamic conditions. A combination of parametric computational modeling and PMHS tests were utilized to examine the effects of impact velocity on C and VC injury metrics. Dynamic OOP scenarios induced metrics greater than the stationary condition as well as impact in absence of airbag. The sensitivity of VC and implications for visceral trauma are also discussed.
