Patent attributes
An inflator device for an inflatable cushion restraint system. The inflator device includes a housing at least in part defining a chamber containing a stored gas. The housing includes a first outlet orifice and a second outlet orifice. A first rupturable seal is disposed over the first outlet orifice and a second rupturable seal is disposed over the second outlet orifice. The second outlet orifice is a pressure release orifice for releasing the pressurized gas upon unanticipated elevated temperatures, such as during bonfire conditions. A plug is disposed in the second outlet orifice. The plug includes a low melting temperature material adjacent the second rupturable seal. The low melting temperature material melts at or below an auto-ignition temperature of the inflator device to allow the second rupturable seal to rupture to vent the pressurized stored gas.
