A hybrid inflator, includes a storage chamber for storing a pressurized gas and a pyrotechnic heater assembly which has a solid gas generating material within a combustion chamber. Forming the outer layer of the pyrotechnic heater assembly is a diffuser, which is inserted into the storage vessel. A closure provides a pressure seal between the storage chamber and the combustion chamber. Upon receiving a control signal, an igniter ignites the solid gas generating material. The closure ruptures, allowing a mixture of hot generated gas and stored gas to discharge through the diffuser and flow into a vehicle occupant restraint.

[ We claim:] [9.] A hybrid inflator for an airbag comprising:a generally cylindrical vessel defining a storage chamber for containing a pressurized gas, said storage chamber having a circular cross section;a pyrotechnic heater assembly at least partially located outside of the cylindrical vessel;a generally cylindrical diffuser around said pyrotechnic heater assembly, the diffuser is inserted into the generally cylindrical vessel, the diffuser being connected to the cylindrical vessel, the diffuser having a reduced diameter portion which is located inside the generally cylindrical vessel and defines a circular opening;a plenum is formed by an end of said vessel and a portion of the diffuser;a closure which is assembled with the reduced diameter portion of the diffuser and extends across said circular opening to provide a pressure seal between the storage chamber and the diffuser, wherein the pyrotechnic assembly creates an orifice through said closure.
