Abstract
An airbag or inflatable cushion assembly can include an inflatable cushion and a throat liner. The throat liner can be coupled to an interior surface of the inflatable cushion at one or more coupling sites. The one or more coupling sites can include one or more panels that can be coupled to at least a portion of both of the inflatable cushion and the throat liner. The one or more panels can be configured to control or inhibit egress of an inflation gas at the one or more coupling sites.
Claims21
An airbag assembly, comprising:
- an inflator configured to generate inflation gas in response to predetermined conditions;
- an inflatable cushion in fluid communication with the inflator at a throat portion, wherein the inflatable cushion comprises a front face and a rear face that cooperate to define a chamber for receiving inflation gas and that meet to form an edge of the inflatable cushion;
- a throat liner comprising an aperture for passage of the inflation gas into the chamber of the inflatable cushion, and a first exterior surface, wherein the throat liner is disposed within the chamber of the inflatable cushion, wherein the first exterior surface is positioned at or adjacent to the edge of the inflatable cushion, and wherein the throat liner is coupled to the inflatable cushion at one or more coupling sites, the one or more coupling sites comprising:
- a first panel coupled to an exterior surface of the inflatable cushion;
- and
- a second panel coupled to an exterior surface of the inflatable cushion, wherein stitching couples at least a portion of the first and second panels, the inflatable cushion, and the throat liner at the one or more coupling sites,
- wherein the first and second panels are configured to at least partially block holes created by the stitching into the chamber to limit egress of inflation gas through the holes.
4 more elements
An airbag, comprising:
- an inflatable cushion coupled to an inflator at a throat portion, the inflatable cushion comprising a front face and a rear face that cooperate to form a void for receiving an inflation gas and that define an edge of the inflatable cushion;
- a throat liner comprising an aperture for passage of the inflation gas into the void of the inflatable cushion, and a first exterior surface, wherein the throat liner is disposed at a position within the void of the inflatable cushion with the first exterior surface adjacent to the edge, and wherein the throat liner is coupled to the inflatable cushion at one or more coupling sites adjacent to the edge of the inflatable cushion, the one or more coupling sites comprising:
- a first panel coupled to an exterior surface of the front face of the inflatable cushion;
- and
- a second panel coupled to an exterior surface of the rear face of the inflatable cushion, wherein stitching couples at least a portion of the first and second panels, the inflatable cushion, and the throat liner at the one or more coupling sites,
- wherein the first and second panels overlap a boundary seam at the edge of the inflatable cushion and the first exterior surface of the throat liner,
- wherein the first and second panels are configured to interfere with holes created by the stitching into the void of the inflatable cushion to at least partially block the holes and thereby limit egress of inflation gas through the holes.
