17. A combination comprising:
-
a cylindrical filter assembly having a central opening with opposed first and second ends;
a closure disposed at the second end of the cylindrical filter assembly; and
a quantity of gas generant material contained within the cylindrical filter assembly, in the central opening thereof, wherein, the first end of the central opening adapted to receive an initiator effective upon actuation to initiate reaction of at least a portion of the quantity of the gas generant material to produce gaseous reaction products;
the closure effective to prevent passage of the gas generant material through the second end of the central opening and the filter assembly having a plurality of layers including an inner layer forming a sleeve member, the sleeve member shapeable to form a plurality of retention tabs effective to secure the closure within the central opening at the second end. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
