Hybrid III Child 6 Year Old
- Standard 6YO ATD 127-0000-H
- Standard Weighted 6YO ATD 167-0000
The Hybrid III 6 Year Old Child Crash Test Dummy was originally developed in 1993 in cooperation with the SAE Biomechanics Committees and the National Highway Traffic Safety Administration (NHTSA). The anthropometry of the dummy is derived from NHTSA Research studies and the biomechanical corridors are derived from scaling of the adult dummies. The dummy went through a complete upgrade in 1997 to enable the dummy to evaluate airbag aggressiveness when a child is close to a deploying airbag. The "Out Of Position" (OOP) test procedures require the dummy to accurately measure neck loading, chest compression, and the Viscous Criterion while being durable and repeatable in these severe test conditions.
The Weighted Hybrid III 6 Year Old dummy is comprised of a standard Hybrid III six-year-old child dummy (Part 572, subpart N) with weights attached to the lateral sides of the spine and the superior surface of the pelvis.
