Abstract
An airbag inflator includes a pressure vessel with a bottom portion, a top portion and a center structure connecting the bottom portion and the top portion. The top portion includes an exit orifice that is closed with a rupturable membrane. An energetics cover attached to the center structure houses a pyrotechnic material, and a diverter is attached to the top portion. The pressure vessel, the energetics cover and the diverter define a gas flow path from inside the energetics cover toward the bottom portion of the pressure vessel, the gas flow path turning at least a first 180 degrees toward the top portion of the pressure vessel and between the energetics cover and the pressure vessel. The longer gas flow path allows time for multi-perforation grain slivers to burn up before exiting the inflator, thereby reducing the amount of particulate exiting the inflator.
