A review of the UM series and of NCSS, NASS, CPIR and FARS Files, as well as Michigan accident data files was undertaken, as well as a review of the NTSB “Rear Seat Study”. From these files rear seat occupany is approximately 10%, with children 6 years of age or less being 1/5th of these. About 50-60% of those in the sear seat are adults. Most of the injuries are at the lower AIS levels, with adults being more seriously injured. Of the more serious or fatal injuries, the head and face predominate by far, in all types of crashes involving unrestrainded rear seat occupants. When belts are worn there are few seriously or fatally injured rear occupants and of these, the abdominal area predominates. From available data, rear lap-belted passengers have the same MAIS level (or less) when compared to their front seat lap-shoulder belted counterparts.
