In the early '90s, engineer Douglas C. Hansen was working for an aerospace firm developing airbag inflators. He discovered there was a lack of understanding regarding airbag systems'how they worked, how they should be handled and how they should be repaired. Propelled by that discovery and recent legislation that required all cars to be equipped with driver and passenger airbags, Hansen and his wife, Victoria, founded Airbag Service. Franchisees work with repair shops and consumers in testing, maintaining and replacing airbags. The company has co-branding relationships with Novus and Apple Auto Glass.
