Abstract: In an airbag system, an airbag obtained by closing each of opposite end portions of a folded metal tube with an end cap is attached to an attachment surface of a front pillar, and the airbag is deployed along the front pillar with a gas produced by an inflator. Therefore, a pedestrian who collides with the front pillar can be protected by the airbag. Since the portion of the airbag, which is away from the end cap toward an intermediate part of the airbag in a longitudinal direction of the airbag by a predetermined distance, is connected to the attachment surface, which is located outside the end cap in the longitudinal direction of the airbag, with a stay being interposed in between, the difficulty in an inflation in a part of the airbag in the vicinity of each end cap, due to the end cap being pressed against the attachment surface when the airbag is inflating, is prevented.

Abstract: An airbag emblem may be backlit or illuminated to provide the emblem with greater visual appeal. In order to accomplish this illumination, an illumination source is used. This illumination source may be electroluminescent foil. The emblem includes colors that are added or inserted onto the emblem. These colors are translucent so that they may be illuminated by the illumination source. This emblem may be placed as part of an airbag cover on a steering wheel.

Abstract: Inflatable airbag cushions often have modular components attached to them after the main airbag has been manufactured. Such modular components can include external tethers, mounting tabs, mounting assemblies, and fill tubes. Often, these modular components are positioned at predetermined locations on the airbag. Further, the modular components typically have a predetermined orientation. Employing an alignment aperture and at least one landmark on the airbag can allow a modular component to be positioned correctly along at least one axis of the airbag. Landmarks can include seams, edges, folds, and marks, such as ink from printing. Additional apertures, landmarks and/or hardware can be used to assure proper orientation of the modular component on the airbag. The modular component can be coupled to the airbag by stitching.

Abstract: A gas generant for an inflatable restraint device (for example, an airbag system for a vehicle) is a monolithic compressed solid that has a linear burn rate of greater than or equal to about 1.6 inches per second at a pressure of about 3,000 pounds per square inch. The gas generant can be in the form of an annular disk having a plurality of apertures. The gas generant may be substantially free of binder and may have a low initial surface area which progressively increases during burning. The gas generant provides a gas generation profile that improves restraint of vehicle occupants, including those occupants that are out-of-position. Additionally, the shaped gas generant decreases occupant exposure to toxic effluent combustion products and solid respirable particulates.

Abstract: Inflatable curtain airbags can be used to mitigate the likelihood of an occupant being ejected from a vehicle through a side window. Inflatable curtain airbags are typically tethered to a vehicle structure on a car-forward side, but may not be tethered to a vehicle structure on their car-rearward side. Increased friction between the car-rearward side of the airbag and an adjacent vehicle structure can be used to help the airbag say in place, and thereby decrease the likelihood of an occupant passing the airbag and being ejected from the vehicle.

Abstract: A multi-stage inflator including a housing at least in part defining first and second combustion chambers each containing a quantity of gas generant reactable to form respective product gases. The inflator includes first and second initiators each operatively associated with a respective one of the combustion chambers in reaction initiating communication with at least a portion of the quantity of the gas generant therein contained such that upon actuation the gas generant ignites to form product gas. The second combustion chamber has an exit opening to allow product gas to exit from the second combustion chamber and into the first combustion chamber. The housing includes at least one discharge opening to permit gas to exit the housing and an end wall and wherein both the first and the second initiators are connected.

Abstract: A post-deployment, position-stabilized curtain airbag has a top edge from which an inflatable safety cushion is supported by a vehicle for deployment into a vehicle passenger compartment between occupant and occupant enclosure. A fill chamber is secured to the top edge of the safety cushion. An inflatable structural member is mechanically connected to the safety cushion. The fill chamber directs pressurized gas into the safety cushion and the structural member. The structural member deploys into the passenger compartment between the safety cushion and occupant enclosure limiting outboard displacement of the safety cushion. The structural member fully deploys after the safety cushion. Another structural member deploys along the top edge of the safety cushion limiting pivoting of the safety cushion there relative to the fill chamber. Pressurized gas enters each structural member through auxiliary passageways having oppositely directed entrances and outlets.

Abstract: An inflator that includes a quantity of gas generant housed within a chamber. A liquid including at least one of a fuel soluble in the liquid or an oxidizer soluble in the liquid and a piston are housed within another chamber of the inflator. This chamber is sealed. Upon actuation, movement of the piston hydraulically expels the liquid through an opening in the piston such that the liquid contacts the gas formed by combustion of the gas generant and cools the same. The fuel and/or oxidizer in the liquid can react to form additional gas.
