An inflatable vehicle occupant protection device (14b) includes a front panel (102b) and a rear panel (122b) that are interconnected to at least partially define an inflatable volume (54b) of the protection device. The rear panel (122b) has a conical configuration resulting from portions of the rear panel being interconnected with each other. The rear panel (122b) comprises portions interconnected along a seam (214), the seam being configured to deviate laterally from a deployment direction so that portions of the air bag that engage and move along the seam shift laterally during deployment to reduce damage due to friction with the seam

The present invention provides a gas generator including: a housing including a top plate, a bottom plate axially opposite to the top plate, and a circumferential wall located between the top plate and the bottom plate and provided with a gas discharge port; a partition wall having a single connection hole and a second communication hole, the partition wall being radially disposed in the housing to partition an interior of the housing into a first combustion chamber on the side of the top plate, which accommodates a first gas generating agent, and a second combustion chamber on the side of the bottom plate, which accommodates a second gas generating agent; an inner cylindrical member disposed in the housing to enclose the first igniter attached to the bottom plate, such that a second end opening side thereof passes through the connection hole in the partition wall in order to be located within the first combustion chamber, closer to the top plate than the partition wall is, and to be spaced from the top plate; the second end opening being closed by a first closing member and the second communication hole being closed by a second closing member; and the gas generating agent also being provided between the top plate and the second end opening closed by the first closing member.

An airbag inflator includes a lower pressure vessel supporting an initiator assembly, a booster can centrally mounted in the lower pressure vessel and secured to the initiator assembly, and an energetics canister secured over the booster can such that the energetics canister is positioned radially between the lower pressure vessel and the booster can. An energetics cover encloses a circumferential space between the booster can and the energetics canister. A flow diverter closes the booster can and includes inlet vent openings downstream of the energetics cover. An upper pressure vessel positioned over the flow diverter and engaging the lower pressure vessel includes an exit orifice sealed with a rupturable membrane. A manifold is secured over the upper pressure vessel. The inflator increases combustion efficiency and lowers gaseous effluents.

An airbag inflator includes a pressure vessel, an initiator positioned at one end of the pressure vessel, a manifold positioned at an opposite end of the pressure vessel, and a generant holder assembly secured in the pressure vessel adjacent the initiator. The generant holder assembly defines an annular space that is configured to secure a generant. A center of the generant holder assembly is open. The open center allows a pressure wave from the initiator to travel to the outlet burst disk.

An inflatable restraint system inflator device having a housing defining an elongated chamber and containing an initial supply of stored inflation gas. An initiator is disposed proximate the first axial end of the housing and an operable closure is disposed proximate the second axial end of the housing. A slidable gas generator assembly is disposed within the chamber between the initiator and the closure and includes a supply of gas generant material reactable upon initiation to produce additional inflation gas. Upon actuation, the initiator and the slidable gas generator assembly cooperate to create a pressure wave to open the closure and to permit release of inflation gas. The slidable gas generator assembly slides within the elongated chamber and gas material reacts to form additional inflation gas.
