Abstract
An air bag for protecting the side and head of an occupant during a side impact collision including: a first side panel (42a) joined to a second panel (42b) and having a neck portion (52) for receipt of inflation gas for a cooperating inflator (30). The air bag characterized in that its upper portion is pressurized to a greater level than a lower portion. A corresponding upper portion of each panel may be coated or alternatively the air bag may include a separator (46) or seam (46,66) to divert a predetermined amount of inflation gas into one of the other chambers.
