Airbag induced injuries to front seated infants and children have resulted in US government recommendations that suggest, among other things, the placement of children into the rear seat area of motor vehicles. During a rear impact, however, most conventional automotive front seats occupied by adults will collapse into the rear seat area. This exposes the rear-seated children to other risks of injuries. Rearward load strength tests run on a wide variety of commercially available automotive front seat systems, such as the single or dual sided recliner types and the stronger belt integrated types, demonstrate a wide range of occupant load resistance. Digital human simulation offers a cost effective, efficient, and accurate means for predicting occupant response and interactions influenced by various types of non-linear deforming seat systems, as well as various types of restraints, and vehicle interior structures.
