A gas generator including a diffuser for diffusing inflation gases generated by an inflator of the gas generator. The gas generator includes at least a first mounting stud. The diffuser has a cylindrical sidewall axially extending between first and second axial ends and circumferentially extending between first and second axially extending sides. A gap is defined between the first and second axially extending sides. The cylindrical sidewall includes a plurality of holes radially extend therethrough and includes a slot having a closed end and an open end. The diffuser circumferentially surrounds a portion of the cylindrical housing of the inflator with the first mounting stud disposed in the slot.

In a shielding state, a partition extends from an upper portion to a lower portion of a cabin in such a manner as to partition a space between a pair of opposing vehicle seats. In the case where the partition is in the shielding state during a collision of a vehicle, the partition is inflated in a vehicle longitudinal direction by gas supplied from an inflator that is actuated when a collision detection sensor detects the collision of the vehicle. That is, since the partition is inflated in the space between the pair of the vehicle seats without interfering with the vehicle seats, the partition can reliably restrain an occupant who receives a collision load and is thereby displaced in the vehicle longitudinal direction from the vehicle seat. In this way, it is possible to easily secure a private space in the cabin and to improve occupant restraint performance.

A vehicle curtain airbag apparatus includes an inflator and an airbag. The airbag includes an airbag body, an inner tube, and a pocket portion. The inner tube includes a tube body and an insertion portion. The pocket portion is provided in a front end portion of the tube body in an insertion direction of the inner tube. A front end portion of the pocket portion in the insertion direction is joined to the tube body at a first joint portion, which extends in an intersecting direction. The intersecting direction intersects the insertion direction. At least one of the opposite end portions of the pocket portion in the intersecting direction is joined to the tube body at a second joint portion that extends in the insertion direction.

Airbag inflator system including a housing defining a flow passage leading into an interior of an airbag). A reverse flow valve is arranged at an inlet end region and selectively enables connection of the flow passage to ambient atmosphere dependent on a pressure differential on opposite sides of the reverse flow valve. A gas generator is arranged in connection with the housing. An activation system provides a signal to the gas generator to cause generation of gas. An aspirator is arranged between the reverse flow valve and the outlet end region and includes an inlet portion alongside the reverse flow valve and an aspiration portion partly separated from the inlet portion to define at least one opening in flow communication with the gas generator. The aspirator is preferably configured to generate gas flow in accordance with the Prandtl-Meyer effect.

An airbag assembly for a motor vehicle including an inflator, an inflatable airbag and a protection device for protecting the throat and fill tube of the inflatable airbag. The inflator is configured for generating inflation gases having an effective exit gas temperature (EGT) less than or equal to 300 degrees Kelvin. The inflatable airbag is formed from one or more panels and defines an interior volume including a plurality of inflatable chambers expandable upon deployment from a stowed state to a deployed state. The interior volume of the inflatable airbag is in fluid communication with the inflator such that inflation gases are passed through the throat and directed to the plurality of inflatable chambers by the fill tube. The one or more panels are constructed from at least one material selected from a group consisting of polyethylene terephthalate (PET), nylon, and combinations thereof. The protection device lines the throat and at least a portion of the fill tube proximate the throat to protect the one or more panels of the inflatable airbag from heat and pressure of the inflation gases.

The invention relates to an airbag (10), especially for a side curtain airbag system (20), comprising an airbag interior (30) which in the deployed state of the airbag (10) defines one single chamber (40), wherein the chamber (40) comprises a gas guiding device (50) by which the chamber (40) is divided into at least one primary filling zone (41) and at least one secondary filling zone (42), as well as to a vehicle safety system equipped with such airbag (10).
