Re: Airbag question (j421)

I think "advanced" airbags differ from "dual stage". The way I understand it, "advanced" airbags include a passenger seat occupant classification sensor to measure weight and sometimes occupant position relative to the airbag. "Dual stage" airbags have two deployment speeds, with the speed selected based on sensor feedback from seat belt use and crash severity. Most new cars today have both of these features on the airbags.
