Airbag flow diversion walls for hot deployment performance levelling

摘要

A thrust neutral passenger side airbag inflation device includes an inflator (10) with a cylindrical casing (16) and a cylindrical housing (12) in which the inflator is concentrically mounted. An annular space between the inflator (10) and the housing (12) is divided by diverter walls (22) into a first zone (40) for supplying inflating gas to an airbag via a housing port (28) and a second zone (42) for venting gas to the atmosphere via hot vent ports (26) in the housing (12). The inflator casing (16) has first ports (18) leading into the first zone (40) and second ports (20) leading into the second zone (42). The diverter walls (22) may extend from and be integrally formed with an outer surface of the inflator casing (16) or an inner surface (24) of the housing (12). <IMAGE>
