Abstract
A study was conducted to develop test procedures and hardware to measure the head injury potential of vehicle upper interiors. The test procedures were derived primarily from the highway accident data files. The impact velocities were derived by using median delta- v levels from injurious accidents, along with laboratory crash pulses and occupant seating information. A number of potential approaches for upper interior testing were reviewed and one particular approach - a free motion headform (FMH), was examined. The results of Hybrid III dummy and FMH testing are compared and discussed.
