Frontal airbag systems for oblique crash protection
First Claim
1. An inflatable airbag system that is configured to be mounted to a steering wheel of a vehicle, the inflatable airbag system comprising:
- an airbag cushion comprising a base cushion portion and an active cushion portion, the base cushion portion and the active cushion portion forming separate chambers in fluid communication, the base cushion portion to receive inflation gas to deploy in an expanded state to provide cushioning restraint to an occupant during a collision event, the active cushion portion disposed on a surface of the base cushion portion that faces an occupant seating position of the vehicle;
an active control mechanism to cause the airbag cushion to deploy in a first configuration if the collision event is a frontal collision event and to cause the airbag cushion to deploy in a second configuration if the collision event is an oblique collision event,wherein the active cushion portion is in an expanded state in the second configuration; and
a tear seam disposed in a panel of the airbag cushion at the active cushion portion of the airbag, the tear seam configured to burst in response to the active control mechanism deploying the airbag cushion in the second configuration to allow the active cushion portion of the airbag to conform to the second configuration.

Abstract
An inflatable airbag system can be configured to be mounted to a frontal region of a vehicle. The inflatable airbag system includes an airbag and an active control mechanism, and is configured to deploy in various configurations in response to frontal and oblique collision events. An active portion of the inflatable airbag deploys to an expanded configuration when a collision event is an oblique collision event and deploys to a less expanded configuration when the collision event is a frontal collision event. The active control mechanism can include one or more tethers or an inflatable member.

14. An inflatable airbag system that is configured to be mounted at a frontal region of a vehicle, the inflatable airbag system comprising:
-
an airbag cushion comprising a base cushion portion and an active cushion portion disposed on an occupant-facing surface of the base cushion portion, the airbag configured to receive inflation gas from the inflator to expand and deploy from the housing to provide occupant crash protection during a collision event; an active control mechanism to receive input indicating a type of collision event and to cause the active cushion portion of the airbag cushion to deploy in a first configuration if the type of collision event is a frontal collision event and to cause the active cushion portion of the airbag cushion to deploy in a second configuration if the type of collision event is an oblique collision event, wherein the active cushion portion of the airbag cushion is expanded in the second configuration and less expanded in the first configuration; and a tear seam disposed in a panel of the airbag cushion at the active cushion portion of the airbag, the tear seam configured to burst in response to the active control mechanism deploying the airbag cushion in the second configuration to allow the active cushion portion of the airbag to conform to the second configuration. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
