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 a positioning member, and is configured to deploy in various configurations in response to frontal and oblique collision events. The positioning member can include a tether or an inflatable member.

Claims

1. An inflatable airbag system that is configured to be mounted to a frontal region of a vehicle, the inflatable airbag system comprising:

an airbag cushion configured to deploy in response to a collision event; and

a positioning member configured to allow 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 positioning member comprises a single tether,

wherein a central portion of the airbag cushion is configured to be disposed at a first location in the first configuration and a second location in the second configuration, the second location being inboard relative to the first location with respect to the vehicle in which the inflatable airbag system is configured to be mounted, and

wherein the central the portion of the airbag cushion is configured to be disposed at the second location in response to an interaction between the airbag cushion and the positioning member.

2. The inflatable airbag system of claim 1, wherein the frontal region comprises an instrument panel of a vehicle.

3. The inflatable airbag system of claim 1, wherein the tether is in an uncoupled state when the airbag cushion is in the first configuration and a coupled state when the airbag cushion is in the second configuration.

4. The inflatable airbag system of claim 1, wherein the tether does not affect the conformation of the airbag cushion in the first configuration.

5. The inflatable airbag system of claim 1, wherein an outboard facing edge of the airbag cushion is configured to be disposed at a third location in the first configuration and a fourth location in the second configuration, the fourth location being inboard relative to the third location with respect to the vehicle in which the inflatable airbag system is configured to be mounted.

6. The inflatable airbag system of claim 1, wherein in the second configuration the tether is configured to extend from a car-forward location to a car-rearward location at an angle that is towards an outboard direction of the vehicle in which the inflatable airbag system is configured to be mounted.

7. An inflatable airbag system that is configured to be mounted to a frontal region of a vehicle, the inflatable airbag system comprising:

an airbag cushion configured to deploy in response to a collision event; and

a positioning member that is configured to allow 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 positioning member comprises a single tether, wherein the positioning member is in a coupled state prior to the collision event, the positioning member being configured to uncouple if the collision event is a frontal collision event and remain in the coupled state if the collision event is an oblique collision event, wherein in the second configuration the tether is configured to extend from a car-forward location to a car-rearward location at an angle that is towards an outboard direction of the vehicle in which the inflatable airbag system is configured to be mounted.

8. The inflatable airbag system of claim 7, wherein the tether does not affect the shape of the airbag cushion when it is uncoupled.

9. The inflatable airbag system of claim 7, wherein the positioning member is configured to cause a central portion of the airbag cushion to be disposed in a second location in the second configuration, the second location being inboard relative to a first location where the central portion of the airbag is configured to be disposed in the first configuration.

10. The inflatable airbag system of claim 7, wherein an outboard facing edge of the airbag cushion is configured to be disposed at a first location in the first configuration and a second location in the second configuration ,the second location being inboard relative to the first location with respect to the vehicle in which the inflatable airbag system is configured to be mounted.
