Abstract

A vehicle includes an instrument panel, a front airbag, a first side curtain airbag, and a second side curtain airbag and two front seats. The front seats are disposed between the first side curtain airbag and the second side curtain airbag. The vehicle includes a roof, and the front airbag is supported by the roof. The front airbag extends from the first side curtain airbag to the second side curtain airbag between the instrument panel and the front seats to absorb energy from occupants during an impact event to reduce the likelihood of head injury and to urge the occupants to remain seated in an upright position to reduce chest loading by seat belts. The front airbag may protect an unbelted occupant ejecting out of the vehicle through a windshield in a crash event.

Claims

1. A vehicle comprising:

an instrument panel;

a roof;

a first side curtain airbag;

a second side curtain airbag;

two front seats disposed between the first side curtain airbag and the second side curtain airbag; and

a front airbag supported by the roof extending from the first side curtain airbag to the second side curtain airbag between the instrument panel and the front seats;

wherein the front airbag further includes a protruded chamber extending toward at least one of the front seats.

2. The vehicle of claim 1, further comprising a headliner with the front airbag extending from the headliner.

3. The vehicle of claim 2, wherein the first and second side curtain airbags extend from the headliner.

4. The vehicle of claim 2, further comprising an inflator disposed in the headliner.

5. The vehicle of claim 1, further comprising a steering wheel, wherein the front airbag extends between the steering wheel and the front seats.

6. The vehicle of claim 5, wherein the steering wheel is movable from a deployed position to a stowed position beneath the instrument panel, the front airbag extending between the steering wheel and the front seats in the deployed position.

7. The vehicle of claim 5, wherein the front airbag includes a bottom edge disposed beneath the steering wheel.

8. The vehicle of claim 5, wherein the front airbag includes a transparent panel adjacent to the steering wheel.

9. The vehicle of claim 1, further comprising a vehicle pillar and the front airbag includes an inflator disposed in the vehicle pillar.

10. The vehicle of claim 9, further comprising an impact sensor and a controller in communication with the inflator.

11. The vehicle of claim 1, further comprising a mechanism for selectively releasing the protruded chamber toward at least one of the front seats.

12. The vehicle of claim 1, wherein the first side curtain airbag includes an end proximal to the instrument panel, the front airbag extending between the end of the first side curtain airbag and the instrument panel.

13. The vehicle of claim 1, wherein the front airbag includes a bottom edge, the first side curtain airbag has an end proximal to the instrument panel, the second side curtain airbag has an end proximal to the instrument panel, and the bottom edge extends from the end of the first side curtain airbag to the end of the second side curtain airbag.

14. The vehicle of claim 1, further comprising a windshield and a steering wheel disposed between the windshield and the front airbag.

15. The vehicle of claim 14, wherein the front airbag further includes a protruded chamber extending toward the windshield.

16. A vehicle comprising:

a steering wheel;

a roof;

a headliner;

a first side curtain airbag extending from the headliner;

a second side curtain airbag extending from the headliner;

two front seats disposed between the first side curtain airbag and the second side curtain airbag; and

a front airbag supported by the roof extending from the headliner and extending from the first side curtain airbag to the second side curtain airbag between the steering wheel and the front seats;

wherein the front airbag includes a bottom edge disposed beneath a bottom edge of the steering wheel.

17. The vehicle of claim 16, further comprising an instrument panel, wherein the first airbag has an end proximal to the instrument panel the front airbag extending between the end of the first side curtain airbag and the instrument panel.

18. The vehicle of claim 16, wherein the front airbag further includes a protruded chamber extending toward at least one of the front seats.

19. A vehicle, comprising:

a roof;

a headliner supported by the roof;

a first side curtain airbag extending from the headliner;

a second side curtain airbag extending from the headliner;

a first front seat and a second front seat each disposed between the first and second side curtain airbags;

a first front airbag extending from the headliner adjacent the first side curtain airbag; and

a second front airbag extending from the headliner adjacent the second side curtain airbag;

wherein the first front airbag includes a protruded chamber extending toward the first front seat and the second front airbag includes a protruded chamber extending toward the second front seat.

20. A vehicle comprising:

an instrument panel;

a roof;

a first side curtain airbag;

a second side curtain airbag;

two front seats disposed between the first side curtain airbag and the second side curtain airbag;

a steering wheel; and

a front airbag supported by the roof extending from the first side curtain airbag to the second side curtain airbag between the instrument panel and the front seat;

wherein the front airbag extends between the steering wheel and the front seats and wherein the front airbag includes a transparent panel adjacent to the steering wheel.
