An air bag having a tri-state vent, in an initial state the vent is configured to be closed, the vent in a medial state configured to be at least partially open or fully open as the air bag is starting to inflate permitting some inflator gas to exit through the vent and the vent in a final state configured to be at least partially closed or fully closed as the air bag continues to inflate.

Airbag with multi-state vent

An air bag () has an inflatable chamber () defined by a main front panel () and a pair of side panels (). The air bag () has a vertically oriented recessed portion () spanning along most of the length of the main panel or a limited section thereof. The recessed portion () divides the air bag () into two lower lobe portions () on each side of the recessed portion. Upon inflation an internal tether () 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.

Air bag with groove or recess, open or partially covered

An air bag () having a main panel () having face panel portion () 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 (), the opening having an edge (). A cup-shaped structure () of material is fitted within the opening and sewn or secured to the edge () of the main panel opening (); 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 () upon inflation, wherein the cup-shaped structure forms a groove or depression () between the lobes.

Grooved air bag

An airbag () has an inflatable chamber () defined by a main front panel () and a pair of side panels (), (). The airbag () has a vertically oriented recessed portion () on the main panel () located on a lower portion of an airbag (), preferably vertically at or below a gas inlet passageway (). The recessed portion () divides the airbag () into two lower lobe portions () on each side of the recessed portion (). Upon inflation an internal tether () 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 airbag () is useful as a frontal airbag, particularly a passenger frontal airbag.
