Abstract: An airbag can include a first cushion portion that defines a first inflatable chamber and a second cushion portion that is connected to the first cushion portion and defines a second inflatable chamber. The first inflatable chamber can receive inflation gas from an inflator to expand the first cushion portion and the second cushion portion can receive inflation gas from the first inflatable chamber to expand the second cushion portion. In some arrangements, a temporary fastener may maintain the second cushion portion in a compact state during expansion of the first cushion portion.

Abstract: Heat shields are used to shield an airbag from hot gasses issuing from an inflator. The heat shields can have a low thermal conductivity and may be capable of melting during a deployment event.

Abstract: A restraint system for a seat is provided and may include a first portion having a first end fixed for movement with the seat and a second end movable relative to the seat. The restraint system may also include a second portion having a first end fixed for movement with the seat and a second end movable relative to the seat and selectively attached to the second end of the first portion. An inflator may be associated with the second portion and may move the second portion from a pre-deployed state to an inflated state. The inflator may be at least partially disposed within the second portion.

Abstract: An airbag assembly can include an inflator that may exert forces on an airbag housing during deployment of an airbag from the housing. The airbag assembly can include a load distributing plate to distribute or delocalize the forces. In some arrangements, the load distributing plate can be attached to the inflator.

Abstract: A restraint system for a seat is provided and may include a first portion formed from a first material and having a first end fixed for movement with the seat and a second end movable relative to the seat. A second portion may be integral with or attached to the first portion, may be formed from the first material, and may be operable between a pre-deployed state and an inflated state.

Abstract: A frontal airbag has a first section, a second section, and a third section, the second section being in fluid communication with both the first and the third section. The first, second and third sections form a triangular structure upon inflation of the airbag. A gas generator is attached to the first section and in fluid communication with the first section. An end portion on the third section remote from the second sections attached to the first section in an area between the gas generator and the second section. Two side tethers attached to the first section and to one of the second and third sections or near transitional bend between the second and third section provide resistance against flattening of the airbag after inflation. The first section and the third section are directly attached to each other by a seam, by an adhesive, or by lamination.

Abstract: An airbag arrangement for protecting at least one seat occupant in an aircraft of the type having a tandem seat arrangement with a rear seat for a seat occupant and a front seat in front of the rear seat. The front seat has an airbag subassembly mounted in the seat back. The airbag subassembly has an airbag inflating between the seat back and the rear seat and uses a gas generator connected to the airbag and configured to inflate the airbag. The airbag is secured to the seat back under a cover with a tear seam and has a compacted state in which the airbag is rolled up or folded about a horizontal axis inside the seat back.

Abstract: A restraint system for a seat is provided and may include a belt portion having an inflatable portion movable from a pre-deployed state to an inflated state. The inflatable portion may include a first surface opposing an occupant when in the inflated state and a second surface facing away from the occupant when in the inflated state. The first surface and the second surface may be formed at an angle relative to one another.

Abstract: Some airbag assemblies can include a housing, an airbag, and a cover. The cover can include a tear seam that is configured to break to permit the airbag to exit the housing. The tear seam can include discrete break columns at which the tear seam ruptures.

A second portion may be integral with or attached to the first portion, may be formed from the first material, and may be operable between a pre-deployed state and an inflated state.

Abstract: An airbag assembly can include a housing and an airbag cushion within the housing in a packaged state. The airbag cushion can include a rolled region and an accordion fold. The rolled region and the accordion fold can be positioned within the housing so as to provide a desired trajectory when the airbag cushion is inflated.

Abstract: An airbag assembly can include a stabilizer strap attached to an airbag, and the stabilizer strap can cooperate with a housing to prevent undesired rotation or skewing of the airbag during deployment. In some arrangements, a portion of the airbag is secured to the housing via an inflator.

Abstract: Airbag covers include a covering portion adapted to at least substantially cover a portion of an airbag housing, and a plurality of tabs positioned to extend at least substantially transverse from the covering portion. The plurality of tabs are adapted to be coupled with a portion of an airbag housing. Each tab comprises an opening therein, and at least one tab of the plurality of tabs comprises at least one tear seam. Airbag modules including such covers further comprise a housing including an inflatable cushion and an inflator disposed at least partially therein. The housing comprises a plurality of cover retention components, each including a portion thereof disposed within an opening of a respective tab of the airbag cover. In forming an airbag cover, a covering portion with a plurality of tabs transversely extending therefrom are formed, and at least one tear seam is formed in at least one tab.

Abstract: An inflatable knee airbag can have a plurality of inflatable chambers. The inflatable chambers can be formed as independent chambers, rather than a single chamber being divided by an internal tether. The inflatable chambers can be arranged in a serial configuration, wherein the chambers form an “L” shape so that when the airbag is deployed, it conforms to the shape of an instrument panel.

Abstract: Vents in inflatable airbags can be used to soften airbags during deployment by allowing inflation gas to exit from the interior of the airbag. Airbag vents can be used in conjunction with vents in an airbag housing and a vent panel that can align with airbag vent with the housing vent and cover the aperture of the housing vent.
