More than 50 years ago the federal government ordered car makers to install seat belts.

Originally designed for an average American man – 5 feet, 9 inches tall and 170 pounds – they have saved millions of lives, but one third of adults in this country are now obese, and seatbelts aren’t working so well for them.
