Abstract
The objective of this paper is to report and analyze the results of sled and barrier crash tests comparing the responses of the Hybrid II and Hybrid III dummies in identical severity tests with belt and /or air bag restraint systems. This paper reports on an analysis of the data from a series of tests. The data indicate that in non- head contract simulations with belt restraint systems, Hybrid III HIC's are nearly 50% higher than Hybrid II HIC's.
