Presented are the results of 23 belt protected postmortem human subjects (PMHS) in 0° barrier impacts at collision velocities of either 30 km/h, 50 km/h or 60 km/h; as well as 8 frontal collisions with 3-point belt restrained PMHS at impact angles between 35° and 45° and velocities between 38 and 45 km/h.
For both test configurations the most frequently injured area of the vertebral column was the cervical-thoracic junction. The injury severity was independent of the occurrence of head impact and was most frequently AIS 1 or 2.
Kinematic analysis of 23 tests (0° barrier impacts) was performed. A logistic regression of head acceleration along the path versus injury severity was calculated. When head acceleration along the path, weight and age were all considered; 64% of the observed values fitted the logistic regression model.
