Abstract:

This study developed and demonstrated modified restraint systems for front seat occupants that can help provide reduced injury. The tests used the 50th percentile male Test device for Human Occupant Restraint (THOR) in both left and right oblique frontal crashes. Four baseline sled tests (driver near-side, driver far-side, passenger near-side, and passenger far-side) set up the baseline restraint performance. Then a set of baseline MAthematical DYnamic MOdels (MADYMO) were developed and validated against the baseline sled tests as well as Federal Motor Vehicle Safety Standards (FMVSS) No. 208 and the United States New Car Assessment Program (US-NCAP) frontal barrier tests. Nearly 100 sled tests and hundreds of MADYMO simulations systematically selected and tuned proposed restraint designs in four oblique crash conditions. Two modified restraint systems, a 3-point belt and relocated retractor, and a suspender 4-point belt, were used in the final sled tests. Results demonstrated that modified restraint systems can be tuned to help reduce the injury in oblique frontal crashes.
