An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first chamber and a second chamber that inflates forward of the first chamber. The second chamber may have a height above the height of the first chamber so that a bottom of the second chamber is pressed downward adjacent to a door of the vehicle. A plurality of airbag assembly components may be integrally formed with a non-inflating peripheral region surrounding the first and second chambers. Such components may include a front or rear tether cut from the front or rear of the non-inflating peripheral region, a top tether cut from the top of the non-inflating peripheral region to control deployment of the second chamber, and a fabric shield cut from the top to at least partially wrap around the stowed inflatable curtain airbag.

Cost-effective use of one-piece woven fabric for curtain airbags

An airbag for a vehicle comprising an inflatable portion and lugs arranged at the periphery of the inflatable portion. The airbag is made of a one-piece-woven technology having a structure made of warp threads and weft threads. The airbag further comprises a marking for enabling a detection of an incorrect attachment of the airbag at the vehicle. The marking is realized by a coded weaving structure in at least one lug.

Airbag for a vehicle

An inflatable curtain airbag can be used to cushion an occupant during a vehicle collision as well as retaining the occupant within the vehicle during a rollover event. Curtain airbags that do not extend to the vehicle's waist line may allow the occupant to fit between the bottom of the curtain airbag and the waistline, and thereby be ejected from the vehicle. This risk is increased with vehicles that do not have vertical pillars between the doors and windows of the vehicle. Increasing an inflation gas volume capacity of a lower portion of the airbag, may mitigate the risk of occupant ejection, if the increased volume portion of the curtain overlaps the vehicle pillars. The lower portion of the curtain airbag may have a first chamber and a separate second chamber.

Inflatable curtain airbags with expanded-volume lower portions for ejection mitigation

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.

Textile gas guides for use with inflatable cushions

Inflatable airbag cushions are filled with inflation gas by inflators. The inflators can be coupled in fluid communication with the airbag and are typically mounted within a vehicle structure by a coupling and closing member. The coupling and closing member can be an elongated piece of a flexible material that wraps around an inflator attachment feature on the airbag. The coupling and closing member can also have structures for fixedly attaching the member to a vehicle structure.

Integrated airbag closing and inflator mounting members for inflatable airbag assemblies

An inflatable airbag cushion assembly with a tether system for use in a vehicle. The airbag and the tether are configured such that upon airbag deployment the tether applies sufficient tension to the cushion to mitigate occupant ejection from the vehicle.

Tether systems for inflatable cushions

An ejection mitigation system for use in a motor vehicle including one or more inflatable airbags and at least one ejection mitigation panel which is not integral with an inflatable airbag and wherein the ejection mitigation panel is attached to at least one point below the belt line of the motor vehicle.

Ejection mitigation panel

An airbag device for use in a motor vehicle. The airbag device includes an inflatable curtain and a cinch ring for tightening a tether during the inflation of the inflatable curtain.
