Abstract
First and second air bag cushion portions are joined to form a bi-lobular air bag cushion with an opening adapted to receive inflation gas from an air bag inflator. A first inner panel forms first and second chambers in the first cushion portion and provide for fluid communication therebetween proximate to a distal portion thereof. A second inner panel forms third and fourth chambers in the second cushion portion and provide for fluid communication therebetween proximate to a distal portion thereof. Relatively inboard first and third chambers are in fluid communication with one another. The second and fourth chambers are in fluid communication with the opening. In another embodiment, first and second distribution tubes provide for fluid communication between the opening and relatively distal portions of the first and second cushion portions. The inner panels and the distribution tubes provide for lateral inflation of the bi-lobular air bag.
