A side curtain airbag (110, 210, 310, 410, 510) for use with a linear gas generator or inflator. In one embodiment, the airbag (110, 210, 310, 410) includes a first panel (113, 213, 313, 413), a second panel (114, 214, 314, 414) adjacent the first panel, and a plurality of elliptically-shaped seams (116, 220, 320, 420) connecting the adjacent panels to define a plurality of inflation fluid flow passages (117, 217, 317, 417) between the seams. In another embodiment, the airbag includes a first panel (513), a second panel (514) adjacent the first panel, and a plurality of substantially straight seams (520) connecting the adjacent panels to define a plurality of inflation fluid flow passages (517) between the seams (520). Use of the seam patterns described herein in side airbag systems allows for improved airbag performance, particularly when used in conjunction with a linear inflator. Inflation of the airbag takes place in a more uniform manner, reducing the risk of localized overpressurization and seam bursting, and improving occupant protection. Moreover, the seam patterns disclosed herein are relatively simple, and their manufacture is relatively easy and inexpensive. |
