![]() ![]() Video footage and greasepaint applied to the dummy’s head must confirm that the restraints prevented the head from hitting the vehicle interior or coming too close to the front seatback and also prevented the dummy’s body from “submarining,” or sliding forward beneath the lap belt, which causes abdominal injuries. ![]() To earn a good rating, measurements recorded by sensors in the second-row dummy must not exceed limits indicating an excessive risk of injury to the head, neck, chest, abdomen or thigh. The new test incorporates a Hybrid III dummy representing a small woman or 12-year-old child positioned in the second row behind the driver and uses specific metrics that focus on the injuries most frequently seen in rear-seat occupants. The Subaru Ascent also earned a “good” rating on the new IIHS testing. In the aforementioned pair as well as the Tesla Model Y, the rear dummy’s head came close to hitting the front seatback, which represents an increase of “the risk of head injuries.” ![]() The rear dummy suggested there was a slight risk of head or neck injuries in the Subaru Ascent and Ford Explorer. “The four good ratings in this round of testing show that some automakers are already doing it.”Īlthough four received high marks, they weren’t perfect, according to IIHS. “Zeroing in on weaknesses in rear seat safety is an opportunity to make big gains in a short time, since solutions that are already proven to work in the front can successfully be adapted for the rear,” said IIHS Senior Research Engineer Marcy Edwards, who led the development of the updated test. The organization updated the test because researched revealed that improvements in front seat safety in recent years wasn’t matched by a similar gain for rear passengers. Although the test still includes a driver dummy, rear passenger protection is the main thing currently differentiating vehicles in this test. How did so many midsize SUVs suddenly become unsafe? IIHS recently updated its longstanding moderate overlap front crash test to add a rear passenger dummy positioned behind the driver. The rear seat passenger in nine of the 13 midsized SUVs suffered a variety of injuries. ![]()
