A total of 42 rear-end collision crash tests with 53 anthropometric test dummies were evaluated. Of the 53 dummies, 32 were positioned in the driver’s seat, 6 in the front passenger’s seat, and 15 in the right-rear seat. 45 were instrumented 50th percentile male and 8 were instrumented 5th percentile females. Linear acceleration in the x, y, and z directions were recorded during each test for each dummy. Additionally, the head injury criteria (HIC) was calculated for each test and each dummy. Student t-tests were performed in order to determine statistically significant differences (p<0.05) between gender and seated position for both HIC and linear acceleration.
