Abstract

Systems and devices for implementing airbags within vehicles are described herein with the airbags being designed to utilize a reduced interior surface area of a vehicle. In one embodiment, an airbag device for a vehicle, comprises an airbag capable of being deployed upon detection of a collision condition for the vehicle and a container to contain the airbag prior to deployment. In one example, the container has a depth that exceeds a diameter of the container.

Claims

1. An airbag device for a vehicle, comprising:

an airbag capable of being deployed upon detection of a collision condition for the vehicle; and

a container to contain the airbag prior to deployment with the container having a depth that exceeds a diameter of the container, wherein the container containing the airbag is located within a steering column of the vehicle and positioned in a lower region of the steering column, wherein the airbag is capable of being deployed through a center region of a steering wheel of the vehicle upon detection of the collision condition, wherein the steering column is a non rotating drive by wire steering column, and wherein a position and an orientation of the airbag device is constant during rotation of the steering wheel.

2. The airbag device of claim 1, wherein the container comprises a tubular, cylindrical, or conical container.

3. The airbag device of claim 1, wherein an end of the container having the diameter is in plane with respect to a surface within an interior of the vehicle.

4. The airbag device of claim 1, wherein the container containing the airbag has a major axis that exceeds a minor axis of the container.

5. A steering column of a vehicle, comprising:

an external housing; and

an airbag device comprising an inflation module and an airbag contained within the external housing, wherein the airbag device is contained within the external housing of the steering column and positioned in a lower region of the steering column, wherein the airbag is capable of being deployed by the inflation module through a center region of a steering wheel upon detection of a collision condition for the vehicle, wherein the steering column is a non-rotating drive by wire steering column, and a position and an orientation of the airbag device is constant during rotation of the steering wheel.

6. The steering column of claim 5, wherein the airbag device has a depth that exceeds a diameter of the airbag device.

7. The steering column of claim 5, wherein the airbag device comprises a tubular, cylindrical, or conical airbag device.

8. The steering column of claim 5, wherein the airbag device has a major axis that exceeds a minor axis of the airbag device.

9. An airbag system for a vehicle, comprising:

a control module to provide safety features; and

an airbag device coupled to the control module, the airbag device is capable of being deployed upon detection of a collision condition by the control module and the airbag device prior to deployment having a depth that exceeds a diameter of the airbag device, wherein the airbag device comprises an inflation module and an airbag contained within a steering column of the vehicle, wherein the airbag device is positioned in a lower region of the steering column and is capable of being deployed by the inflation module through a center region of a steeling wheel upon detection of the collision condition, wherein the steering column is a non-rotating drive by wire steering column, and a position and an orientation of the airbag device is constant during rotation of the steering wheel.

10. The airbag system of claim 9, further comprising:

a plurality of sensors coupled to the control module, the plurality of sensors to sense motion data and to transmit the motion data to the control module for detection of the collision condition.

11. The airbag system of claim 9, wherein the airbag device comprises a tubular, cylindrical, or conical airbag device.

12. The airbag system of claim 9, wherein an end of the airbag device having the diameter is in plane with respect to a surface within an interior of the vehicle.

13. The airbag system of claim 9, wherein the airbag device has a major axis that exceeds a minor axis.
