Comparison Tests of BioRID II and RID 2 with Regard to Repeatability, Reproducibility and Sensitivity for Assessment of Car Seat Protection Potential in Rear-End Impacts

This study investigates the kinematics, repeatability, sensitivity and reproducibility of the BioRID II and RID 2 dummies in sled tests in order to identify how well different cars seats protect their occupants. Three types of seats were used to test the interaction of various car seat shapes and mechanical properties with the dummies. The responses of the dummies were evaluated based upon current whiplash injury criteria. Due to its simpler design, the RID 2 showed better reproducibility and repeatability than the BioRID II. Neither dummy ranked consistently on rear-end, low speed impact protection potential.
