Abstract:

A 12-participant test-track study in a sedan, a minivan, and a pickup assessed head excursions across vehicles using two abrupt braking events, two lane changes, and turn-and-brake maneuvers. Forward head excursion was slightly smaller in the passenger car than in the other two vehicles. No explanation for this finding was apparent; the vehicle kinematics were similar. A larger study with 90 participants was then conducted using a passenger sedan and an SUV with a range of age and body size assigned to blocks of initial conditions. Factors investigated were seat position, foot placement, seat back recline angle, retractor locking, vehicle differences, and effects of leaning inboard on the console armrest or leaning forward while reaching. All 90 experienced two braking events, a right-going lane change, a left-going lane change, and a turn-and-brake maneuver. Overall, results suggest a range of occupant head locations can be produced by abrupt vehicle maneuvers. More research is needed to assess the robustness of occupant protection systems to this wide range of postures.
