In this study, an attempt was made to compare injury rates to restrained occupants in airbag deployed and nonairbag deployed vehicles in four different countries. Analyses were conducted both on “raw” data-sets and also with assumptions that injuries to the lower limbs are unaffected through interaction with a deploying airbag. This study reveals problems with comparing data from more than one country and highlights a requirement for a harmonised global approach to accident data collection particularly with a corresponding growth in vehicle export markets.
