We all know that there is airbag in cars, but what do you know about it? This article talks some basical knowledge about auto airbag system: what is auto airbag, its operating principle and how to reset airbag.

What is an auto airbag?

An auto airbag is a vehicle safety device. The airbag is an occupant restraint consisting of a flexible envelope designed to inflate rapidly during an automobile collision, to prevent occupants from striking interior objects such as the steering wheel or a window. Modern vehicles may contain multiple airbags in various side and frontal locations of the passenger seating positions, and sensors may deploy one or more airbags in an impact zone at variable rates based on the type and severity of impact; the airbag is designed to only inflate in mild to severe frontal crashes. Airbags are normally designed with the intention of supplementing the protection of an occupant who is correctly restrained with a seatbelt. Most designs are inflated through pyrotechnic means and can only be operated once.
