Abstract

An inflator (10) for a vehicular air bag. The inflator (10) has a metal cover (18) and metal base (16) sealingly secured to each other by a weldless joint. The cover (18) or the base (16) has a circumferential lip (30) defining a channel (32) and a rim (34) of the other of the cover (18) and base (16) is received within the channel (32). The cover (18) and base (16) are shaped such that an external portion of the lip (30) abuts the other of the cover (18) and base (16) to form a joint which sealingly connects the cover (18) and base (16) and secures the cover (18) and base (16) together. In a disclosed embodiment, the cover (18) and base (16) are of stamped metal and the base (16) has a circumferential lip (30) defining a channel (32) or through which receives an external circumferential lip (30) portion of the lip, an external portion of the lip (30) being in abutment with the cover (18), the channel and lip portions thus being shaped to interlock with each other.

Claims

AMENDED CLAIMS
[received by the International Bureau on 9 February 1995 (09.02.95); original claims unchanged; new claims 17 and 18 added (1 page)]
17. An inflator for a vehicular air bag, the inflator having an outer housing, an ignitor located centrally thereof, a propellant chamber circumferentially surrounding the ignitor, and a filter chamber circumferentially surrounding the ignitor chamber, where the propellant chamber is surrounded by an inner housing having a top metal member and a bottom metal member, wherein one or the other of the top and bottom members has a circumferential lip defining a trough and an edge of the other of the top and bottom members is received within the trough, and the top and bottom members are shaped such that an external portion of the lip abuts the other of the top and bottom members to form a joint which sealingly connects the top and bottom members.
18. The inflator of claim 17 wherein the outer housing comprises a metal cover and a metal base wherein one or the other of the cover and base has a circumferential lip defining a channel and a rim of the other of the cover and base is received within the channel, and the cover and base are shaped such that an external portion of the lip abuts the other of the cover and base to form a joint which sealingly connects the cover and base and secures the cover and the base together during operation of the inflator.
