Passenger side airbag module having lengthened reaction canister.

摘要

Passenger-side airbag module comprising a reaction housing (10) with side walls (12) connected to a semi-cylindrical floor (16) and adjacent channels (32) in which tubular portions (48) of a sheet metal diffuser (38) are located. Gas from a gas generator which is shorter than the housing (10) and diffuser (38) enters the housing via an aperture in the floor (16), flows outwardly through a plenum chamber and enters a gas bag through gas openings (52,54) situated adjacent ends of the housing (10) so as to inflate peripheral regions of the gas bag more quickly than a central portion thereof. The horseshoe like form of the deploying airbag will enfold and thus protect a person who is not in the expected position in the vehicle.
