Airbag assembly with tethered reaction surface and cushion configured to permit forward head rotation
First Claim
1. An airbag assembly for mounting above an occupant in a vehicle, the airbag assembly comprising:
- an airbag housing;
an airbag cushion connected to the airbag housing and configured to project outward from the airbag housing when the airbag cushion inflates from an uninflated state to an inflated state, wherein a structure of the vehicle lacks an external reaction surface located on a side of the airbag cushion opposite of the occupant when the airbag cushion is in the inflated state to support the airbag cushion when the occupant contacts the airbag cushion; and
a tether connected at a first attachment point and connected to the airbag cushion at a second attachment point, the first attachment point located horizontally closer to the occupant than the second attachment point when the airbag cushion is in the inflated state such that the tether limits movement of the airbag cushion in a direction away from the occupant.

Abstract
An airbag assembly is configured for mounting above an occupant in a vehicle. The example airbag assembly includes an airbag housing that is configured to enclose an airbag cushion when the airbag cushion is in an uninflated state. The airbag cushion is connected to the airbag housing and is configured to project outward from the airbag housing when the airbag cushion inflates from the uninflated state to an inflated state. The example airbag assembly also includes a tether connected at a first attachment point and connected to the airbag cushion at a second attachment point. The first attachment point is located horizontally closer to the occupant than the second attachment point when the airbag cushion is in the inflated state such that the tether limits movement of the airbag cushion in a direction away from the occupant.
