2007 Ford Expedition Curb-Trip Rollover Crash Test (33 Km/h - Modified Restraints - 3/4 Turn)
This curb trip rollover crash test was conducted to investigate the dynamics of belted occupants during rollover crashes. This test was conducted with a modified 2007 Ford Expedition moving at 33.1 km/h (20.6 mph), releasing the vehicle with its roll axis perpendicular to the direction of the curb trip fixture. The vehicle was modified by replacing the rear seat with a modified front seat to simulate similar characteristics in both seating positions. The center console was also removed. The test vehicle contained three instrumented Part 572E dummies. The OEM belts and buckles were replaced in all positions. The driver, left rear passenger were equipped with motorized and buckle pretensioner, and right front passenger position was equipped with a retractor and buckle pretension 3-PT belt system. The curtain air bags and pretensioners were fired manually at 100ms into the event. The test vehicle was towed laterally on its tires on soap and released two feet prior to impact with the curb. It was conducted for the NHTSA's VRTC by TRC Ohio Inc
