Abstract
An air bag (10) has a deflated condition stored in a container (40) in a vehicle and has an inflated condition. The air bag (10) when in the inflated condition has lower and upper sections (64, 74). The air bag (10) has a first portion (60) forming the lower section (64) of the air bag, and a second portion (70) forming the upper section (74). The air bag (10) includes a back panel (82) disposed farthest from a vehicle occupant (22) and a front panel (80) disposed closest to the occupant. The first portion (60) of the air bag (10) is folded into a compact shape and stored in a lower portion (62) of the container (40). The second portion (70) of the air bag (10) is rolled into a compact shape and stored in an upper portion (72) of the container (40). The second portion (70) inflates upward and unrolls in a direction away from the occupant (22) so that the front panel (80) is presented toward the occupant. The first portion (60) of the air bag (10) inflates before the second portion (70).
