Abstract
Abstract An air bag module is provided in a vehicle having a vertical vehicle axis and having a horizontal vehicle axis. The air bag module includes an inflator having an elongated vertical inflator axis. The inflator discharges inflator gas which is directed in a longitudinal direction perpendicular to the vertical inflator axis. An air bag includes a main body portion having a shape that is angled with respect to the longitudinal direction. Preferably, the longitudinal direction is angled upwardly relative the horizontal vehicle axis and the main body portion of the air bag is angled downwardly relative the longitudinal direction. Preferably, the main body portion includes upper and lower downwardly angled edges which are generally parallel to the horizontal vehicle direction when the air bag is inflated.

Claim 9
Dependent Claim
110 words
The air bag module of claim 1 wherein the longitudinal direction is angled upwardly relative the horizontal vehicle axis and wherein the main body portion of the air bag includes an inboard wall and an outboard wall directly opposite the inboard wall, the main body portion having an upper edge and a lower edge defined by the intersection of the inboard and outboard walls, the upper and lower edges being angled downwardly relative the longitudinal direction approximately the same amount that the longitudinal direction is angled upwardly relative the horizontal vehicle axis whereby upon air bag deployment, the upper and lower edges are generally parallel to the horizontal vehicle axis.
Claim 10
Dependent Claim
40 words
The air bag module of claim 1 wherein the main body portion of the air bag includes a central portion extending in the longitudinal direction and wherein the air bag includes a lower portion extending downward from the central portion.
Claim 11
Dependent Claim
16 words
The air bag module of claim 9 wherein the lower portion has a generally triangular shape.
Claim 12
Dependent Claim
24 words
The air bag module of claim 9 wherein the lower portion has a vertical dimension continually increasing in a direction away from the inflator.
Claim 13
Dependent Claim
23 words
The air bag module of claim 9 wherein the lower portion has a volume substantially equal to or greater than the central portion.
Claim 14
Dependent Claim
37 words
The air bag module of claim 9 wherein the air bag includes an upper portion extending upwardly from the central portion and wherein the upper portion is substantially smaller than the lower portion and the central portion.
Claim 15
Dependent Claim
18 words
The air bag module of claim 9 wherein the lower portion is longitudinally folded atop the central portion.
Claim 16
Dependent Claim
62 words
The air bag module of claim 9 wherein the lower portion is longitudinally folded atop the central portion such that when inflation of the air bag is unrestrained, the inflator gas is biased towards initially filling the central portion and when air bag inflation is obstructed, the inflator gas is biased towards unfolding and filling the lower portion of the air bag.
