An exemplary embodiment can be an inflator module assembly. The inflator module assembly can include a module housing having a plurality of gas discharge openings; an inflator housed within the housing, the inflator, upon actuation, emitting gas from one lateral side or end thereof, and a gas treatment assembly mounted within the housing external the side or end of the inflator from which gas is emitted. The gas treatment assembly can include a first strainer element nestled within a second strainer element. The first and second strainer elements each have a side wall including a plurality of gas passage apertures, with at least either 1) the gas passage apertures of the first strainer element offset relative to the gas passage apertures of the second strainer element or 2) the gas passage apertures of the second strainer element offset relative to the module housing gas discharge openings.

1. An inflator module assembly comprising: a module housing having a plurality of gas discharge openings;an inflator housed within said housing, said inflator comprising an initiator and, upon actuation, emitting gas from one lateral side or end thereof, anda gas treatment assembly mounted within said housing external the side or end of the inflator from which gas is emitted, said gas treatment assembly comprising a first strainer element nestled within a second strainer element, the first and second strainer elements each having a side wall including a plurality of gas passage apertures, with at least either 1) the gas passage apertures of the first strainer element offset relative to the gas passage apertures of the second strainer element or 2) the gas passage apertures of the second strainer element offset relative to the module housing gas discharge openings, wherein gas emitted from the inflator passes through the gas treatment assembly prior to emission from the inflator. 2. The inflator module assembly of claim 1 wherein the gas passage apertures of the first strainer element are offset relative to the gas passage apertures of the second strainer element and the gas passage apertures of the second strainer element are offset relative to the module housing gas discharge openings and wherein gas produced within the inflator passes through the first strainer element and subsequently the second strainer element. 3. The inflator module assembly of claim 1 wherein the plurality of gas passage apertures of at least one of said first and second strainer elements are disposed in an array of at least two rows of holes about the side wall of the respective strainer element. 4. The inflator module assembly of claim 3 wherein the plurality of gas passage apertures of each of said first and second strainer elements are respectively disposed in an array of at least two rows of holes about the side wall of said respective strainer element. 5. The inflator module assembly of claim 1 wherein at least one of the first and second strainer elements is cup-shaped. 6. The inflator module assembly of claim 5 wherein both the first and second strainer elements are cup-shaped. 7. The inflator assembly of claim 1 wherein the gas passage apertures of the first strainer element are arranged in at least two groups, with each group including at least two rows of apertures. 8. The inflator assembly of claim 7 wherein the gas passage apertures of the first strainer element are arranged in at least three groups, with each group including at least two rows of apertures. 9. The inflator assembly of claim 1 wherein the gas passage apertures of the first strainer element are uniformly spaced about the side wall thereof. 10. The inflator assembly of claim 1 wherein the plurality of gas discharge openings are disposed about the module housing in at least two rows. 11. The inflator assembly of claim 1 wherein the inflator contains a quantity of gas generant solid effective upon reaction to produce gas and wherein the gas emitted from the inflator additionally comprises particulate matter resulting from the reacted gas generant solid. 12. The inflator assembly of claim 1 wherein the first and the second strainer elements are sufficiently spaced one from the other such that the spacing does not restrict exit gas flow. 13. The inflator assembly of claim 1 wherein the gas passage apertures of the second strainer element are sized to control combustion pressure within the inflator. 14. An inflator module assembly comprising: a module housing having a plurality of gas discharge openings;an inflator housed within said housing, said inflator, upon actuation, emitting gas from one lateral side or end thereof; anda gas treatment assembly mounted within said housing external the side or end of the inflator from which gas is emitted, said gas treatment assembly comprising a first strainer element nestled within a second strainer element, the first and second strainer elements each having a side wall including a plurality of gas passage apertures, with at least either 1) the gas passage apertures of the first strainer element offset relative to the gas passage apertures of the second strainer element or 2) the gas passage apertures of the second strainer element offset relative to the module housing gas discharge openings,wherein gas passing through at least one of the gas passage apertures of the first strainer element must turn at approximately 90 degrees at least twice to subsequently also pass through one of the gas passage apertures in the second strainer element. 15. The inflator assembly of claim 14 wherein gas passing through at least one of the gas passage apertures of the second strainer element must turn at approximately 90 degrees at least twice to subsequently also pass through one of the module housing gas discharge openings. 16. An inflator module assembly comprising: a module housing having a plurality of gas discharge openings;an inflator housed within said housing, said inflator, upon actuation, emitting gas from one lateral side or end thereof; anda gas treatment assembly mounted within said housing external the side or end of the inflator from which gas is emitted, said gas treatment assembly comprising a first strainer element nestled within a second strainer element, the first and second strainer elements each having a side wall including a plurality of gas passage apertures, with at least either 1) the gas passage apertures of the first strainer element offset relative to the gas passage apertures of the second strainer element or 2) the gas passage apertures of the second strainer element offset relative to the module housing gas discharge openings,wherein gas passing through at least one of the gas passage apertures of the second strainer element must turn at approximately 90 degrees at least twice to subsequently also pass through one of the module housing gas discharge openings. 17. An inflator module assembly comprising: a module housing including at least two rows of gas discharge openings;an inflator housed within said housing, said inflator, upon actuation, emitting gas from one lateral side or end thereof, anda gas treatment assembly mounted within said housing external the side or end of the inflator from which gas is emitted, said gas treatment assembly comprising a first strainer cup element nestled within a second strainer cup element, the first and second strainer cup elements each having a side wall including a plurality of rows of gas passage apertures, with the gas passage apertures of the first strainer element offset relative to the gas passage apertures of the second strainer element and wherein gas passing through the gas passage apertures of the first strainer element must turn at approximately 90 degrees at least twice to subsequently also pass through one of the gas passage apertures in the second strainer element andwith the gas passage apertures of the second strainer element offset relative to the module housing gas discharge openings and wherein gas passing through the gas passage apertures of the second strainer element must turn at approximately 90 degrees at least twice to subsequently also pass through one of the module housing gas discharge openings. 18.
