Abstract: An air bag (100) has an inflatable chamber (101, 301) defined by a main front panel (102, 212) and a pair of side panels (104a, b; 224, 226). The air bag (100) has a vertically oriented recessed portion (110, 220) spanning along most of the length of the main panel or a limited section thereof. The recessed portion (110, 220) divides the air bag (100, 210) into two lower lobe portions (112a, b, 240, 242) on each side of the recessed portion. Upon inflation an internal tether (180, 250) is attached to the recessed portion and is anchored at or adjacent to the gas inlet passageway thereby limiting forward movement of the recessed portion upon inflation. The air bag is useful as a frontal air bag, particularly a passenger frontal air bag.

Abstract: A curtain air bag module (100) comprising and air bag (102) having at least one inflatable region with internally configured internal tethers and a deflector or ramp locatable above a B-pillar trim part and loosely mounted to the vehicle and to the trim part.

Abstract: A curtain air bag module (100) comprising an air bag (102) having at least one inflatable region with internally configured internal tethers, at least one of the internal tethers disposed at an angle to a stream of inflation gas. The air bag includes a distribution tube located proximate a top portion of the at least one inflatable region of the air bag, the tube having a first end adapted to receive inflation gas, the distribution tube including at least one set of openings proximate each of the at least one inflatable regions for communication of inflation gas to these regions, the at least one internal tether disposed at an oblique angle to the distribution tube.

Abstract: An air bag (100) having a main panel (102) having face panel portion (103) configured to face an occupant when the air bag is inflated, the main panel in the vicinity of the face panel portion including an opening (130, 130a, 130b), the opening having an edge (140). A cup-shaped structure (149,150,152,160) of material is fitted within the opening and sewn or secured to the edge (140) of the main panel opening (130); the cup-shaped structure is located within the air bag below the exterior surface of the main panel. A tether anchored at one end and having a second end secured to a portion of the cup-shaped structure, the length of the tether configured to prevent the cup-shaped structure from moving beyond the exterior surface of the main panel, the cup-shaped structure and remaining parts of the air bag forming opposing lobes (112a, 112b) upon inflation, wherein the cup-shaped structure forms a groove or depression (110) between the lobes.

Abstract: A side curtain air bag assembly is provided, which has an inlet configured to receive inflation gas, a plurality of inflatable chambers; and a distribution tube in fluid communication with the inlet of the air bag. The inlet and the distribution tube are configured to cause inflation gas to flow along the air bag in a predetermined direction, and the distribution tube has a conical portion configured to reduce the pressure of the inflation gas pressure that is communicated from the inlet, and to distribute the inflation gas to the inflatable compartments of the air bag.
