Abstract

Systems and methods of vehicle protection increase the amount of safety provided for the occupants of the vehicle. The disclosed systems and methods are particularly useful in the event of a rollover or roof deformation. In one aspect, a vehicle airbag system includes an inflatable airbag positioned on an interior surface of a vehicle, the vehicle including a roof surface and one or more side surfaces. The airbag, when deployed, is adapted to from a cushion between the roof surface and occupants of the vehicle.

Claims

1. A vehicle airbag system, comprising:

an inflatable airbag positioned on an interior surface of a vehicle, the vehicle including a roof surface and one or more side surfaces;

wherein said airbag, when deployed, is adapted to inflate to a location between the roof surface and occupants of the vehicle.

2. The system of claim 1, wherein said inflatable airbag, when undeployed, is positioned within a headliner on the roof surface.

3. The system of claim 2, wherein said inflatable airbag includes one or more fabric bags positioned between the headliner and the roof surface.

4. The system of claim 3, wherein said inflatable airbag, when undeployed, is folded in pleats within the headliner.

5. The system of claim 3, wherein said inflatable airbag, when deployed, protrudes through the headliner.

6. The system of claim 2, wherein said inflatable airbag is a cavity formed between the headliner and the roof surface.

7. The system of claim 6, wherein, when the airbag is deployed, said cavity expands to form a cushion.

8. The system of claim 1, further comprising:

at least one sensor to facilitate detection of a rollover of the vehicle; and

a controller adapted to deploy the inflatable airbag when a rollover is detected.

9. The system of claim 8, wherein the controller is further adapted to actuate one or more actuators to inflate the airbag when a rollover is detected.

10. The system of claim 2, wherein the headliner includes a plurality of layers and wherein one of the layers includes an airbag.

11. The system of claim 1, further comprising a sensor for detecting whether a seat belt is buckled and a controller configured to prevent deployment of the airbag when the seat belt is not buckled.

12. The system of claim 1, further comprising a system for detecting and classifying the occupant of a vehicle seat and a controller configured to control the deployment of the airbag based on the results of the occupant classification.

13. A method for providing airbag protection for vehicle occupants, comprising:

detecting a rollover; and

deploying one or more airbags, at least one or the airbags being an inflatable airbag positioned on an interior surface of a vehicle, said inflatable airbag, when deployed, being adapted to from a cushion between the roof surface and occupants of the vehicle.
