Hybrid II 50th Male


Available Product Lines

  • Denton Brand - SA-150-M002 (ATD Assembly, non-instrumented)


The Hybrid II 50th Percentile Male Test Dummy, originally designed by Alderson Research Laboratories, was modified by General Motors and the National Highway Traffic Safety Administration (NHTSA) using Alderson and Sierra Engineering parts. This dummy was capable of generating test data with sufficient biofidelity to be used for automotive crashworthiness testing. In 1973, the dummy was mandated by NHTSA for use in testing automotive restraint systems to meet Federal Motor Vehicle Safety StandardNo.208 (FMVSS 208).

Non-automotive applications for the Hybrid II test dummy include equipment and injury potential studies of recreation vehicles, wheel chairs, medical equipment and sports gear.

The size and weight of the Hybrid II 50th Percentile Male Test Dummy represent the "average" of the USA adult male population. The design incorporates the range of motions, centers of gravity and segment masses determined by anthropometric studies to simulate those of human subjects.
