AIR BAG INFLATOR AND METHOD OF MANUFACTURE THEREOF

摘要

An air bag inflator (10) is manufactured by sandwiching a wire mesh filter (39) between a pair of flat elongated perforate strips of steel (18 and 20), thereafter rolling the sandwiched steel strips and wire mesh concomitantly to form a right circular cylindrical tube with the edge portions (34, 36, 40 and 42) of the steel strips orientated in juxtaposed relation to one another, respectively; and welding (62) the juxtaposed edge portions of the strips by a common weld that extends radially across the edge portions of both of the steel strips.
