The new inflatable seat belt is designed to inflate in a mere 40 milliseconds and when expanded the belts spread crash forces over five times more area of the body than conventional seat belts. The new seat belt inflates slower than a conventional air bag and uses cold compressed gas instead of a heat-generating chemical reaction.
"It's a very simple and logical system, but it required extensive trial and error and testing over several years to prove out the technology and ensure precise reliable performance in a crash situation," said Srini Sundararajan, safety technical leader for Ford research and advance engineering.
The new inflatable seat belt will debut first on the next-generation Ford Explorer in 2010 and then it will eventually be offered in vehicles globally.
