First introduced in vehicles in the early 1970s, airbags are large fabric sacs designed to inflate immediately after a crash. The purpose of airbags is to protect occupants from hitting the hard interior of the vehicle. Airbags can be installed in many places within the vehicle, including the dashboard, steering column, side-panels, and around the knees. The inflation of an airbag happens very quickly, and can cause minor injuries to vehicle occupants who are unbelted or who aren’t properly positioned within the vehicle.
