Frontal, lateral and rear-end collisions with dummy occupied wheel chairs on a deceleration sled were conducted in two test series at a collision velocity of 30 km/h, and a sled deceleration of 8 and 12 g. In the first dummy test series conventional restraint systems were used; in the second test series improved restraint systems were employed. In a further series, four cadaver tests were conducted. For all tests and collision directions the HIC values, as well as the resultant acceleration at the center of gravity lay below the admissible values of Federal Motor Safety Standard 208. Despite the low thorax accelerations numerous rib fractures occurred in the cadaver tests. In two cadaver tests, injury degrees of AIS 5 were observed (multiple liver ruptures, vertebral column injuries).

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.
