Neck Injuries Poised To Drop Thanks To New Law—And New Seats Page 2

October 27, 2009

But IIHS spokesman Russ Rader says that his group is also playing a part in getting these seat designs rolled out before the law requires it. "Part of what's driving it is that manufacturers have to earn 'good' ratings in the rear test in order to get the Top Safety Pick designation," says Russ Rader, spokesman for the IIHS, adding that automakers are using it as a competitive advantage.

The IIHS rear crash protection ratings are based on two categories of testing: first, on geometric measurements regarding how close the head restraint is to an average man's head; and secondly, on dynamic ratings that test the seat and head restraints on a sled, simulating a velocity change of 10 mph, which is like being in a stationary vehicle struck at 20 mph.

Over the next year, we'll also start seeing some changes to back seats, too. Phasing in beginning in September 2010—and required by September 2011—is a new federal requirement that rear-seat head restraints be mounted as high as 29.5 inches from the occupant's hip (the same height as for front-seat restraints)

The new seats might cost slightly more in some cases—especially the ones with active restraints that move upward and forward in an impact for better support—but it's nothing compared to the pain in the neck the injuries have proven to insurance companies and motorists. Neck injury is the most common injury reported under the two most common types of auto-injury insurance, according to Rader, and the annual cost amounts to $9 billion—one quarter of all accident-related injury claims.

Even considering the new seat design in the Sebring and Avenger, these two models still scored an 8 out of 10 for Safety in's Meta Review because of imperfect (four out of five) scores in a couple of federal ratings and because electronic stability control remains an option—even for top-of-the-line models.
