We claim:

1 . A vehicle occupant safety system for helping to protect front seat occupants of a vehicle in the event of a collision that results in oblique forward occupant movement, comprsing:

a frontal air bag inflatable between an instrument panel and the front seat vehicle occupant; and

a central air bag inflatable adjacent and inboard of the frontal air bag;

wherein the frontal air bag is configured and positioned to receive and cushion the vehicle occupant moving in an oblique direction in the vehicle as the result of a vehicle collision, and

wherein the central air bag is configured and positioned to support an inboard portion of the frontal airbag against flattening out in response to receiving the obliquely moving occupant, and to engage the obliquely moving occupant's head and resist rotation of the vehicle occupant's head resulting from moving obliquely into engagement with the frontal air bag.

2. The safety system recited in claim 1 , wherein the central air bag is also configured to receive and absorb impact energy of the obliquely moving occupant.

3. The safety system recited in claim 1 , wherein the central air bag is configured to deploy in a direction that is rearward and outboard in the vehicle so as to engage and support the frontal air bag.

4. The safety system recited in claim 1 , wherein the central air bag is configured to extend rearward of the frontal air bag so that, as the obliquely moving occupant penetrates the frontal air bag, portions of the frontal air bag displaced by the penetrating occupant cause the central air bag to arc around the side of the obliquely moving occupant's head to provide support for the head that acts against rotation.

5. The safety system recited in claim 1 , wherein the central air bag when engaging the frontal air bag provides inboard support for the frontal air bag that resists collapse of the frontal air bag in response to receiving the obliquely moving occupant.

6. The safety system recited in claim 5, wherein in response to inboard support being overcome and the frontal air bag collapsing in response to receiving the obliquely moving occupant's head, the central air bag is configured to arc toward the back of the occupant's head and couteract the tendency for the occupant's head to rotate.

7. The safety system recited in claim 1 , wherein the central air bag is a pillow shaped bag having an elongated configuration with a longitudinal axis that extends obliquely relative to the longitudinal vehicle axis in a direction that is rearward and outboard of the vehicle.

8. The safety system recited in claim 1 , wherein the central air bag helps support the occupant's head against rolling as a result of moving obliquely into engagement with the frontal air bag.

9. The safety system recited in claim 1 , wherein the frontal air bag is an instrument panel mounted passenger frontal air bag and the central air bag is mounted to the instrument panel inboard of the frontal air bag, the central air being configured to deploy rearward and outboard toward the passenger side of the vehicle into engagement with the passenger frontal air bag.

10. The safety system recited in claim 9, further comprsing a steering wheel mounted driver frontal air bag, wherein the central air bag is also configured to have a portion inflatable adjacent an inboard portion of the driver frontal air bag to receive and cushion driver side occupant moving obliquely inboard as the result of a vehicle collision.

1 1 . The safety system recited in claim 10, wherein the central air bag is configured to engage the driver frontal air bag.

12. The safety system recited in claim 10, wherein the central air bag is configured to reach at least one of the instrument panel and a vehicle steering column.

13. The safety system recited in claim 10, wherein the central air bag is configured to extend into contact with the passenger frontal air bag so that the passenger frontal air bag serves as a reaction surface for the central air bag when receiving a driver side occupant moving obliquely inboard into engagement with the central air bag.

14. The safety system recited in claim 13, wherein the central air bag is configured to extend into contact with the instrument panel so that the instrument panel serves as a reaction surface for the central air bag when receiving a driver side occupant moving obliquely inboard into engagement with the central air bag.

15. The safety system recited in claim 1 , wherein the central air bag is configured to be mounted to the instrument panel, the steering column, or to other vehicle structure in the vicinity of the instrument panel.

16. A vehicle occupant safety system for helping to protect front seat occupants of a vehicle in the event of a collision that results in oblique forward occupant movement, comprsing:

a passenger frontal air bag inflatable between an instrument panel and the front seat passenger side vehicle occupant; and

a central air bag positioned inboard of the passenger frontal air bag and inflatable rearward and outboard in the vehicle into engagement with the passenger frontal air bag;

wherein the central air bag supports an inboard portion of the passenger frontal air bag, using the instrument panel as a reaction surface, against flattening out in response to receiving an obliquely moving occupant.

17. The safety system recited in claim 16, wherein the central air bag engages the obliquely moving occupant's head and resists rotation of the vehicle occupant's head resulting from moving obliquely into engagement with the frontal air bag.

18. The safety system recited in claim 17, wherein the central air bag is configured to extend rearward of the passenger frontal air bag so that, as the obliquely moving occupant penetrates the passenger frontal air bag, portions of the frontal air bag displaced by the penetrating occupant cause the central air bag to arc around the side of the obliquely moving occupant's head to provide support for the head that acts against rotation.

19. The safety system recited in claim 16, wherein the central air bag is a pillow shaped bag having an elongated configuration with a longitudinal axis that extends rearward and outboard of the vehicle.

20. The safety system recited in claim 16, further comprsing a steering wheel mounted driver frontal air bag, wherein the central air bag is also configured to have a portion inflatable adjacent an inboard portion of the driver frontal air bag to receive and cushion driver side occupant moving obliquely inboard as the result of a vehicle collision.

21 . The safety system recited in claim 20, wherein the central air bag is configured to engage the driver frontal air bag.

22. The safety system recited in claim 20, wherein the central air bag is configured to extend into contact with the passenger frontal air bag so that the passenger frontal air bag serves as a reaction surface for the central air bag when receiving a driver side occupant moving obliquely inboard into engagement with the central air bag.

23. A vehicle occupant safety system for helping to protect front seat occupants of a vehicle in the event of a collision that results in oblique forward occupant movement, comprsing:

a driver frontal air bag inflatable from a vehicle steering wheel between an instrument panel of the vehicle and a driver side front seat occupant of the vehicle;

a passenger frontal air bag inflatable from the instrument panel between the instrument panel and a passenger side front seat occupant of the vehicle; and

a central air bag positioned between the driver frontal air bag and passenger frontal air bag and being inflatable away from the instrument panel rearward and outboard toward the passenger side of the vehicle, the central air bag when inflated engaging the passenger frontal air bag and having portions adjacent or engaging the driver frontal air bag.
