Abstract: An apparatus (10) for helping to protect a vehicle occupant in the event of a collision comprises an inflatable vehicle occupant protection device (12) and an inflator (14, 114). The inflator (14, 114) has a source of inflation fluid (48, 148) in a chamber (46) of the inflator (14, 114) for inflating the protection device (12). The inflator (14, 114) includes a passage (68) through which inflation fluid flows from the chamber (46) into the protection device (12). The inflator (14, 114) also has a burst disk (44) which blocks the passage (68). An actuatable source (90) of laser light, when actuated, emits laser light which impinges on the burst disk (44) to cause the burst disk to rupture and release the inflation fluid from the chamber (46).

Abstract: An apparatus for helping to protect a vehicle occupant in the event of a collision comprises an inflatable vehicle occupant protection device 12. An inflator 14 having a source of inflation fluid 48 for inflating the protection device 12 includes a passage 30 through which the inflation fluid 48 flows from the inflator 14 into the protection device 12. A member 60 for regulating the flow of the inflation fluid 48 through the passage 30 defines a first orifice 68, through which inflation fluid 48 flows, of a first fluid flow area when no electric current is applied to the member 60 and defines a second orifice 68a, through which inflation fluid 48 flows, of second fluid flow area larger than the first fluid flow area when electric current is applied to the member 60.

Abstract: An apparatus (10) comprises an inflatable vehicle occupant protection device (12) and an actuatable inflator (14) for, when actuated, providing inflation fluid to inflate the inflatable vehicle occupant protection device. A retaining ring (16) is attached to the inflatable vehicle occupant protection device (12). The retaining ring (16) encircles the inflator (14) and defines an annular chamber (88) disposed radially outward of a plurality of outlet openings (26) in the inflator (14). The retaining ring (16) includes a circumferentially spaced plurality of exit ports (90) in fluid communication with the annular chamber (88). The annular chamber (88) and the exit ports (90) redirect the inflation fluid flowing out of the outlet openings (26) into the inflatable vehicle occupant protection device (12). The inflation fluid is thus prevented from impinging directly on an inner surface (50) of the inflatable occupant protection device as the inflation fluid is being directed out of the inflator (14).

Abstract: An apparatus (10) comprises an inflatable vehicle occupant protection device (12) and an actuatable inflator (14) for, when actuated, providing inflation fluid to inflate the inflatable vehicle occupant protection device. The inflator (14) includes a circumferentially spaced plurality of radially extending outlet openings (26) and a circumferentially spaced plurality of deflector flanges (30). The deflector flanges (30) are spaced radially from the outlet openings (26) and are radially aligned with the outlet openings. The deflector flanges (30) completely overlie the outlet openings (26). When the inflator (14) is actuated, the deflector flanges (30) deflect the inflation fluid flowing from the outlet openings (26) and thereby prevent the inflation fluid from impinging directly the inflatable vehicle occupant protection device (12) as the inflation fluid is being directed out of the inflator (14).

Abstract: An apparatus comprises an inflatable vehicle occupant protection device (14), an inflator (12), and a vehicle part (18). A structural portion (80) of the vehicle part (18) defines a compartment (84) with an open inner end (86) and an opposed, open outer end (88). The protection device (14) has an installed position received at least partially in the compartment (84) and is inflatable outward through the open outer end (88) of the compartment (84). The inflator (12) also has an installed position received at least partially in the compartment (84), and is movable to its installed position through the open inner end (86) of the compartment. A first fastener structure (120) is located on the structural portion (80) of the vehicle part (18). A second fastener structure (60) is located on the inflator (12).

Abstract: An actuatable inflator (10) for inflating an inflatable vehicle occupant protection device (12) includes a container (70) having a cup-shaped wall including a base portion (72) and a side wall portion (74). The container (70) is a one-piece structure. The base portion (72) and the side wall portion (74) at least partially define a combustion chamber (84) in the container (70). An ignitable material (110) in the combustion chamber (84), when ignited, rapidly increases the fluid pressure inside the combustion chamber. An electrically actuatable initiator (112) ignites the ignitable material (110). The base portion (72) of the cup-shaped wall includes a predefined rupture portion (90). The rupture portion (90) ruptures when the fluid pressure inside the combustion chamber (84) reaches a predetermined elevated fluid pressure level to form an orifice (120) through which the inflation fluid in the combustion chamber flows.
