  • Faster Inflation

    Faster Inflation
    Allen K. Breed, developed a ball-in-tube system for better crash sensors. The airbag took too long to inflate by compressed air so the implementing of a small explosion of sodium azide inflated the bag to a size of maximum safety in 30 milliseconds.
  • First Commercial Use

    First Commercial Use
    In 1974, GM gave the option to put the improved airbags into models of Cadillacs. They gave this option because the buyer could substitute the air bag system for seat belts.

  • Pedestrian Airbags

    Pedestrian Airbags
    The Volvo V40 first introduced the use of pedestrian air bags. These deploy from hard parts of the car like the edges when it senses a collision is imminent with a pedestrian. This gave the car a rating of 88% for pedestrian safety in the EuroNCAP's pedestrian tests.
