DETROIT — Air bags have long been mounted in the steering wheel, dashboard and sides of vehicles. Now, they’re in the seat belts.
Ford plans to introduce seat-belt-mounted air bags in the back seat of the 2011 Ford Explorer sport utility vehicle, which will hit the market next fall. Ford says it is the first automaker to mass-produce the technology. The belts have a cylindrical air bag that stretches from the buckle to the shoulder and fits inside a pocket sewn into the belt.
The car sends a signal that releases the bag, which inflates more gently than a front air bag, so it is safer for children.
Srini Sundararajan, the Ford engineer who was chiefly responsible for developing the device, said the wider belts and bags help distribute crash forces across the occupant’s chest so there is less chance of serious injury.
“The top two lifesaving devices today are the seat belt and the air bag. This combines them into one great feature,” Sundararajan said.
Clarence Ditlow, head of the nonprofit Center for Auto Safety, said the belts are particularly effective at protecting the elderly, who are more frail. The Associated Press
