Evaluation of Child Occupant Protection in a 56 km/h (35 mph) Frontal Barrier Crash

In response to the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act, the agency added child restraints to the rear seat of several frontal crash tests in 2001 and 2002, and in most frontal crash tests for 2003 and 2004 conducted under the New Car Assessment Program (NCAP). Child dummies representing one, three, and six-year-old children were placed in various child restraints, including rear-facing, forward-facing, and booster seats. Tests with the Hybrid III three-year-old showed little variance between different child restraints tested in the same vehicle, but showed significantly greater variance in tests with the same restraint, but different vehicle. Vehicle type had little correlation with test results. Analyses also showed that the Hybrid III three-year-old had a statistically significant better chest G performance than either the CRABI one-year-old and Hybrid III six-year-old dummies. Analysis did not indicate a statistically significant Head Injury Criterion (HIC) performance difference between the Hybrid III three-year-old and either the CRABI one-year-old or the Hybrid III six-year-old, however, the Hybrid III three-year-old dummy tended to have better HIC performance than the Hybrid III six-year-old dummy. In addition, limited analysis showed a rear-facing child restraint system (CRS) that interacts with the front seat tends to result in higher chest readings in the dummy.
