This paper looks at the results of a statistical analysis of side impacts against rigid obstacles; side impact with another vehicle are also considered. The analysis was based on data extracted from the bidisciplinary accident database maintained by INRETSLCB. The study was restricted to accidents since 1980 for reasons of uniformity of coding and deformation measurement accuracy. Multi-variate data analysis was carried out on the database using SPADN, to examine the nature and severity of occupant injuries and also the accident conditions and vehicle deformations. The primary aim of the study was to try and identify possible means of improving occupant protection in side impact.
