A diffuser for a supplemental restraint system includes a top wall, a cylindrical side wall and a bottom wall defining a diffuser chamber. The diffuser is used in a supplemental restraint system having an airbag and a combustion chamber for providing a pressurized gas to inflate the airbag. The combustion chambe r defines an opening therein for exhausting the pressurized gas. The diffuser is a substantially cylindrical member defining a longitudinal axis. The bottom wa ll has an opening having a predetermined flow area, that is adjacent to and separat ed from the combustion chamber opening. The diffuser includes a plurality of elongat ed slots formed therein by lancing, that are generally parallel to the diffuser axis. The slots are configured, and have a flow area, to rapidly inflate the airbag. T he slots are further configured to retain debris generated from the combustion chambe r within the diffuser and to prevent the debris from entering the airbag upon inflation. The slots are formed by lancing that forms first and second flashing portion s on an interior of the cylindrical side all that remain connected to and intact wit h the side wall upon formation.
