Occupant protection device for a motor vehicle

Abstract

Abstract An airbag fitting inside a vehicle has the folded airbag and gas generator mounted as a unit behind the protective cover (1). A shutter (7) is fitted between the airbag and the cover and is pulled aside by the action of the gas generator prior to inflating the airbag. The expanding airbag ruptures the thin outer cover. The shutter is pulled aside by a pull cord (10) which has one end fixed (11) and which is pressed aside by a thrust element (17) driven by a piston (15) which is subjected to the gas pressure. The gas generator operates on two stages; a first stage to pull aside the shutter and a second stage to inflate the airbag.
