Abstract: Textile gas guides adapted for use with inflatable cushions and airbag systems are configured to be formed in a manner that reduces or eliminates the need for specialized equipment during manufacturing, and to be sufficiently reinforced to withstand damage during use. Such textile gas guides may comprise a second edge of a first fabric member overlapping and coupled with a shear seam to a portion of a third edge of a second fabric member. The third edge and a fourth edge of the second fabric member may be coupled together with a second seam sewed through the two edges of the second fabric member. The second fabric member at least substantially encompasses the first fabric member. Airbag systems employing such textile gas guides may include at least one inflatable cushion, a portion of which is coupled to the textile gas guide.
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 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: A “hybrid” inflator having an extended filling capacity is disclosed. This inflator is designed to deploy an inflatable curtain airbag. The inflator will have an inner chamber that is connected to an outer chamber by a bleed hole. The inner chamber has a first supply of gas and a pyrotechnic material. This first supply of gas is sufficient to inflate an inflatable curtain after ignition of the pyrotechnic material. The outer chamber has a second supply of gas. The second supply of gas bleeds out of the outer chamber through the inner chamber and into the inflatable curtain. The inflatable curtain may be initially filled by the first supply of gas in the inner chamber while the second supply of gas slowly bleeds out of the inflator into the curtain to maintain the curtain at a desired pressure sufficient to provide impact protection to the vehicle occupant.
