A curtain airbag attached to a vehicle body and expanded and deployed by a gas from an inflator containing: a first region along a lower edge; a second region adjacent above the first region with a first fold line; a third region adjacent above the second region with a second fold line formed on an opposite side of the first fold line across the second region. The first region is in a condition folded back at the first fold line to face a first surface side of the second region, the second region is in a condition folded back at the second fold line such that the folded back first region is between the second region and the third region, the third region is in a condition rolled upward on a second surface side. Rolling starts from the second fold line.

An airbag device for pedestrian protection includes means for shrinking and tying an airbag after deployment toward the storage. The airbag device includes a protecting sheet that is folded together with the airbag and stored in the storage, and a wrapping sheet that wraps the airbag as folded. The protecting sheet includes a main body and a plurality of straps disposed in a periphery of the main body. The wrapping sheet includes a rupturable portion that is configured to rupture and split the wrapping sheet into a front portion and a rear portion at airbag deployment, and a plurality of through holes each for receiving the straps in a vicinity of the rupturable portion in the front portion. The deployed airbag is shrank and tied toward the storage by passing the straps through the through holes and tying them so the straps do not come off of the through holes.

An air bag module includes an inflatable air bag, an inflator for inflating the air bag, a housing for supporting the air bag and inflator, and a cover for enclosing the air bag in the housing. The cover includes a fabric panel and a steering panel. The fabric panel has a main portion that at least partially envelops the air bag in a deflated and stowed condition and includes a tear seam that is rupturable upon inflation of the air bag to permit the air to deploy from the housing. The steering panel is for directing the air bag to deploy from the housing along a predetermined trajectory. The steering panel includes a panel of reinforcing material that overlies a portion of the fabric panel and is connected to the fabric panel. In a closed condition of the cover, the steering panel is fastened to the housing.

Methods for making an airbag mounting bracket for use with an attachment component of an associated airbag cushion are provided. An opening in a mounting bracket precursor formed of a bracket precursor material is extruded. A rounded surface of the bracket precursor material adjacent the extruded opening is formed. The mounting bracket precursor with the rounded surface is subsequently finalized to form the airbag cushion mounting bracket, wherein the extruded opening provides an airbag attachment engagement opening for passage of the attachment component and the rounded surface provides a load bearing surface of increased area for the attachment component. Also provided are corresponding or associated airbag mounting brackets.

A head-protecting airbag device includes a case which houses an airbag in a folded-up configuration and a mounting bracket which is used to mount an inflator on a vehicle body structure. The case is mounted on a region of the airbag extending from one end of the inflator. The mounting bracket includes an insert region which fits in an assembling opening of the case. The assembling opening includes a receiving region which receives the insert region along an axial direction of the inflator and a limiting plane that is located in a periphery of the receiving region and holds the insert region from rotating in both directions in a circumferential direction of the inflator. The fitting of the insert region and assembling opening suppresses the airbag stored in the case in the folded-up configuration from rotating in a circumferential direction.
