Publication details: Göteborg Chalmers University of Technology, 2013Description: 40 sSubject(s): Online resources: In: European Enhanced Vehicle-safety Committee. Working Group 12. Document Number 578 final versionAbstract: In the past, EEVC WG12 and 20 have evaluated rear-impact dummies and reviewed associated injury criteria and assessment reference values for seat performance evaluations. The BioRID II was recommended to be used in future legislative dynamic rear-end impact seat performance tests. Recommended injury criteria and assessment reference values to be used with the dummy are however still pending. This is mainly due to the incomplete understanding of the injury site and mechanisms responsible for the symptoms presented after such impacts. This lack of biomechanical data limits the possibility to evaluate any proposed injury criteria and associated reference values. The aim of this study is to address these limitations by comparing crash test dummy parameter values from performed sled tests with real-life accident data.In the past, EEVC WG12 and 20 have evaluated rear-impact dummies and reviewed associated injury criteria and assessment reference values for seat performance evaluations.
