Abstract

An air bag module (60) including an inflatable air bag (50) having a first region formed by opposing edge borders (102, 104) of two facing panels or panel pieces (52, 54), the first region initially open to receive a gas distribution hose (40), the gas distribution hose comprising a tubular portion (42) and a flat portion (44) integrally formed with the tubular portion, the tubular portion configured to receive inflation gas at one portion and having openings (49) therein to permit the egress of inflation gas; the flat portion of the hose located between the opposing edge borders of the facing panels; and a seam or seams (110) extending through the facing borders to join the flat portion of the hose between the facing edge borders in a gas tight manner.

Claims

1. An air bag module (60) comprising an inflatable air bag (50) having a first region formed by opposing borders (102, 104) of two facing panels or panel pieces (52, 54), the first region initially open to receive a gas distribution hose placed therebetween;

the gas distribution hose (40) comprising a tubular portion (42) with a wall and a flat portion (44) extending from the wall, the tubular portion and flat portion formed as a unit;

the tubular portion configured to receive inflation gas at one portion and having openings (49) therein to permit the egress of inflation gas,

the flat portion of the hose located between the opposing borders of the facing panels; and

a seam or seams (100, 113, 114) extending through the facing borders to join the flat portion of the hose between the facing edge borders in a gas tight manner; and

wherein one of the borders of the air bag includes an extending portion (52a) which extends outward further than the other border, the extending portion of the one border wrapped over an exposed edge of the tubular portion and the extending portion of the one border positioned adjacent and parallel to a portion of the cover and parallel with the other border and secured thereto.

2. The air bag module according to claim 1, further including a cover (22) wrapped about the air bag when the air bag is in a compact configuration, the cover including a first panel portion located between a first surface of the flat portion of the hose and a portion of the one border below the extending portion of the one border, the cover including a second panel portion located between a second surface of the flat portion of the hose, the second surface opposite the first surface, the wrapped-over portion of the one border also wrapped over and located on an outer side of the second panel of the cover.
