Abstract
An inflator (14) for inflating an inflatable vehicle occupant restraint (12) includes ignitable gas generating material, an igniter (260) for igniting the gas generating material, and a housing (50) having a tubular wall (52) surrounding the gas generating material. The housing (50) further has an end wall (54) defining a closed end of the housing (50). The housing (50) contains a tubular structure (62) including a cylindrical filter (70) for the gas. The tubular structure (62) extends coaxially within the tubular wall (52) and has an axially inner end portion (180) adjacent to the end wall (54). A sealing structure engages the tubular structure (62) to block gas from bypassing the filter (70) by flowing around the inner end portion (180) of the tubular structure (62). The sealing structure includes a pair of opposed sealing surfaces (94, 150) which extend circumferentially around the axis (40) and which face radially toward each other. The inner end portion ( 180) of the tubular structure (62) is compressively engaged by, and is compressed between, the opposed sealing surfaces (94, 150).
