1. An airbag assembly comprising:
- a housing configured to be mounted in a dashboard of a vehicle at a first position;
an inflator; and
an airbag cushion that comprises;
a first cushion portion that defines a first inflatable chamber that is configured to receive inflation gas from the inflator to expand the first cushion portion from a compact state to a deployed state, wherein the first cushion portion is configured to deploy from the housing when the housing is mounted in the dashboard of the vehicle at the first position, and wherein the first cushion portion is configured to receive a torso of a vehicle occupant when the vehicle occupant moves from a vehicle occupant position primarily in a forward direction relative to the vehicle;
a second cushion portion connected to the first cushion portion, wherein the second cushion portion defines a second inflatable chamber that is configured to receive inflation gas from the first inflatable chamber to expand the second cushion portion from a compact state to a deployed state to cover a second portion of the dashboard that is closer to a center of a vehicle than is the first portion of the dashboard; and
at least one discrete vent that is internal to the airbag cushion and provides fluid communication between the first and the second inflatable chambers to permit inflation gas to flow freely from the first inflatable chamber to the second inflatable chamber and to permit inflation gas to flow freely from the second inflatable chamber to the first inflatable chamber.

Abstract
An airbag can include a first cushion portion that defines a first inflatable chamber and a second cushion portion that is connected to the first cushion portion and defines a second inflatable chamber. The first inflatable chamber can receive inflation gas from an inflator to expand the first cushion portion and the second cushion portion can receive inflation gas from the first inflatable chamber to expand the second cushion portion. In some arrangements, a temporary fastener may maintain the second cushion portion in a compact state during expansion of the first cushion portion.

50. An assembly for restraining an occupant during a collision event, the assembly comprising:
-
a housing configured to be mounted adjacent a dashboard of a vehicle at a first position; an inflator; and an airbag cushion that comprises; a first cushion portion that defines a first inflatable chamber that is configured to receive inflation gas from the inflator to expand the first cushion portion from a compact state to a deployed state, wherein the first cushion portion is configured to deploy from the housing when the housing is mounted adjacent the dashboard of the vehicle at the first position, and wherein the first cushion portion is configured to receive a torso of a vehicle occupant when the vehicle occupant moves from a vehicle occupant position primarily in a forward direction relative to the vehicle; a second cushion portion connected to the first cushion portion, wherein the second cushion portion defines a second inflatable chamber that is configured to receive inflation gas from the first inflatable chamber to expand the second cushion portion from a compact state to a deployed state to cover a second portion of the dashboard that is closer to a center of a vehicle than is the first portion of the dashboard; and at least one discrete vent that is internal to the airbag cushion and provides fluid communication between the first and the second inflatable chambers to permit inflation gas to flow freely from the first inflatable chamber to the second inflatable chamber and to permit inflation gas to flow freely from the second inflatable chamber to the first inflatable chamber; and a bucket seat configured to provide a vehicle occupant position for a single occupant, wherein the first airbag cushion deploys toward the vehicle occupant position upon inflation, and the second airbag cushion deploys from the first airbag cushion toward the center of the vehicle upon inflation to receive the vehicle occupant when the vehicle occupant moves from the bucket seat in an oblique direction during the collision event.
