Abstract

An airbag is provided. The airbag is configured to extend longitudinally along a side of a vehicle and includes a first section configured to inflate in a longitudinal and vertical direction, a second section coupled to the first section and configured to inflate in a longitudinal and vertical direction, an inlet for receiving inflation gas from an inflator, tabs positioned at the top of the airbag for attaching the airbag to a ceiling of the vehicle and chambers positioned between the tabs along the top of the airbag, wherein the chambers stabilize the airbag during deployment.

Claims

1. An airbag configured to extend longitudinally along a side of a vehicle comprising:

a first section configured to inflate in a longitudinal and vertical direction;

a second section coupled to the first section and configured to inflate in a longitudinal and vertical direction;

an inlet for receiving inflation gas from an inflator;

tabs positioned at the top of the airbag for attaching the airbag to a roof-rail or vehicle side structure of the vehicle; and

chambers positioned between the tabs along the top of the airbag, wherein the chambers stabilize the airbag during deployment.

2. An airbag as claimed in claim 1, wherein the first section and second section have multiple vertical chambers.

3. An airbag as claimed in claim 1, wherein the first section and second section are coupled such that air may flow between the first section and the second section.

4. An airbag as claimed in claim 1, wherein the inlet is positioned at the top of the airbag between the first section and second section.

5. An airbag as claimed in claim 1, wherein the tabs are elongated such that when the airbag is deployed the bottom of the airbag is positioned below a beltline of the vehicle.

6. A vehicle, comprising:

an airbag configured to extend longitudinally along a side of a vehicle including;

a first section configured to extend in a longitudinal and vertical direction;

a second section coupled to the first section and configured to extend in a longitudinal and vertical direction;

an inlet for receiving inflation gas from an inflator;

tabs positioned at the top of the airbag for attaching the airbag to a ceiling of the vehicle; and

chambers positioned between the tabs along the top of the airbag, wherein the chambers stabilize the airbag during deployment.

7. A vehicle as claimed in claim 6, wherein the first section and second section have multiple vertical chambers.

8. A vehicle as claimed in claim 6, wherein the first section and second section are coupled such that air may flow between the first section and the second section.

9. A vehicle as claimed in claim 6, wherein the inlet is positioned at the top of the airbag between the first section and second section.

10. A vehicle as claimed in claim 6, wherein the tabs are elongated such that when the airbag is deployed the bottom of the airbag is positioned below a beltline of the vehicle.
