Abstract: A container of metal capable of withstanding an internal overpressure includes a hollow vessel for containing contents having an essentially cylindrical side wall and two outwardly curved end walls formed as partial spherical surfaces. At least one of the curved end walls has a central bulge protruding as a cup-shaped bottom from the curved end wall. A container connecting pipe is mounted on the central bulge of the at least one curved end wall. An intended breaking point is integrated in at least one of the partial spherical surfaces formed by one of the end walls, wherein the intended breaking point is a notch formed in an outer side of the end wall, and wherein the notch has varying depths with a maximum depth and a minimum depth.

Abstract: An inflator (10) for providing inflation fluid to inflate an inflatable vehicle occupant protection device includes a pressure vessel (12) defining a chamber (30) for inflation fluid. The pressure vessel (12) has a passage (48) for inflation fluid flow from the chamber (30). A burst disk (52) blocks fluid flow through the passage (48). A support (62) has a tubular portion (64) with a first end (67) spaced apart from the burst disk (52) prior to the inflation fluid entering the pressure vessel (12) and a second end (68) opposite the first end. The burst disk (52) deforms into contact with the first end (67) due to the pressure of the inflation fluid when the inflation fluid is disposed in the chamber (30). An actuatable igniter assembly (60) bursts the burst disk (52) to enable fluid to flow from the chamber (30) through the passage (48). The second end (68) of the tubular portion (64) engages the igniter assembly (60).

Abstract: An improved rupture disk assembly for a pressure relief system is disclosed. The rupture disk assembly is sealed between an inlet support member and an outlet support member, each of which define a central fluid pathway. A rupture disk that includes a flange connected to a dome-shaped rupturable portion by a transition area is sealed between the support members. The rupturable portion may include an indentation positioned at the apex of the dome and a score line having a first and a second end. A safety member that has a hinge including a knuckle and a tongue is positioned between the rupture disk and the outlet support member. The knuckle extends downwardly into the dome and extends laterally across the dome to a point that is inside the area circumscribed by the score line or inside the area circumscribed by an arc connecting the two ends of the score line.
