there are still surprisingly large numbers of people who think that they do not need to wear seat belts while driving along busy highways. they are very wrong. in a head-on highway collision, passengers without a seatbelt are thrown against the dashboard of the car and serious injury is often the result.
seat belts can reduce the impact experienced by a passenger to one-fifth of the impact suffered by the body of the car. air bags are equally important. a growing interest in passenger safety has made air bags a selling feature on automobiles.
an air bag is made of a coated fabric and is stored in a module mounted on the steering wheel or dashboard. crash sensors are mounted in several locations on the car.
