This document summarizes a study that used finite element analysis to evaluate vehicle interior safety features. The study analyzed head injury criteria (HIC) from impacts of a free motion headform at various points inside a vehicle model, both with and without interior trim components. The results showed that HIC exceeded the safety standard limit of 1000 during impacts on the bare vehicle structure but were below 1000 when trim components were included, indicating that trim design can help reduce head accelerations and injuries in crashes.
