Claim 14:
15. An overhead airbag assembly comprising:
a housing to be coupled to a roof structure of a vehicle; an inflator;
an airbag cushion configured to deploy from the housing with inflation gas from the inflator and expand from a packaged state to a deployed state disposed forward of a vehicle seating position;
a main chamber with a first end adjacent to the housing and a second end;
an extension chamber that extends away from the main chamber at the second end toward the vehicle seating position, the extension chamber configured to deflect relative to the main chamber in a vertical direction, the main chamber and the extension chamber defining a cavity to receive a head of an occupant seated in the vehicle seating position during a collision event;
a lower chamber, wherein the extension chamber is disposed between the main chamber and the lower chamber,
wherein a portion of the main chamber provides a reaction surface that is configured to engage a structure of the vehicle to reduce rotation of the airbag cushion about a y-axis of the vehicle during occupant loading; and
a vertical internal panel tether that couples to a vehicle facing portion of the main chamber and to an occupant facing portion of the main chamber, wherein the vertical internal panel tether comprises a planar surface arranged vertically within the overhead airbag cushion in the deployed state, and wherein the vertical internal panel tether extends across a first opening between the main chamber and the extension chamber and across a second opening between the main chamber and the lower chamber.
