The paper presents and describes results of the FAT research-project Phase I “Kinematics and Loadings during Side Impacts: Comparison between Dummies and Cadavers”. It will report on 30 side impacts at 50 km/h under 90° impact angle conducted with three different dummies and cadavers. On the basis of the test results dummy modifications will be proposed. The side impacts caused following main injuries in the cadavers: rib fractures on the impacted side were most frequently observed (AIS thorax 2-4). The most serious injuries were liver ruptures predominantly on right-side impacted cadavers (AIS up to 5). Cervical spine injuries with an AIS value of 1 and 2 were also noted. Fracture of the pelvis occurred only in one, bony head injuries in two cases.
