Abstract

An apparatus (10) includes an inflatable vehicle occupant protection device (32). The vehicle occupant protection device (32) has a stored condition and an inflated condition in which the occupant protection device extends across an upper portion (20) of a vehicle windshield (14). The occupant protection device (32) has first and second end portions (38,40) located adjacent first and second A pillars (18,16) of the vehicle when in the inflated condition. An inflator (34) emits inflation fluid to inflate the occupant protection device (32) from the stored condition to the inflated condition. The inflator (34) is mounted in one of the first and second A pillars (18, 16) of the vehicle.

Claims

1. Apparatus comprising:

an inflatable vehicle occupant protection device having a stored condition and an inflated condition in which said vehicle occupant protection device extends across an upper portion of a vehicle windshield, said vehicle occupant protection device having first and second end portions located adjacent first and second A pillars of the vehicle when in the inflated condition; and

an inflator for emitting inflation fluid to inflate said vehicle occupant protection device from the stored condition to the inflated condition, said inflator being mounted in one of the first and second A pillars of the vehicle.

2. Apparatus as defined in claim 1 wherein said vehicle occupant protection device is located in a headliner of the vehicle adjacent the upper portion of the windshield when in the stored condition.

3. Apparatus as defined in claim 1 wherein said vehicle occupant protection device expands in a direction toward the upper portion of the windshield and away from an occupant of the vehicle as said vehicle occupant protection device inflates from the stored condition to the inflated condition.

4. Apparatus as defined in claim 1 wherein said first and second end portions of said vehicle occupant protection device are located adjacent the first and second A pillars when said vehicle occupant protection device is in the stored condition.

5. Apparatus comprising:

a first inflatable occupant protection device having a stored condition and an inflated condition in which said first occupant protection device extends adjacent an upper portion of a vehicle windshield;

a second inflatable occupant protection device having a stored condition and an inflated condition in which said second inflatable occupant protection device extends adjacent a lower portion of the vehicle windshield;

a first inflator for emitting inflation fluid to inflate said first occupant protection device from the stored condition to the inflated condition;

a second inflator for emitting inflation fluid to inflate said second occupant protection device from the stored condition to the inflated condition.

6. Apparatus as defined in claim 5 wherein the vehicle has first and second A pillars and said first inflator is mounted in one of the first and second A pillars of the vehicle.

7. Apparatus as defined in claim 6 wherein said first occupant protection device has first and second end portions connected with first and second A pillars of the vehicle, said first occupant protection device extending across the upper portion of the windshield when in the inflated condition.

8. Apparatus as defined in claim 5 wherein said first occupant protection device is located in a headliner of the vehicle adjacent the upper portion of the windshield when in the stored condition.

9. Apparatus as defined in claim 5 wherein said second occupant protection device is located in a steering wheel when in the stored condition.

10. Apparatus comprising:

an inflatable vehicle occupant protection device having a stored condition and an inflated condition in which said vehicle occupant protection device extends across an upper portion of a vehicle windshield, said vehicle occupant protection device having first and second end portions, only said first and second end portions of said vehicle occupant protection device being connected to the vehicle when in the inflated condition; and

an inflator for emitting inflation fluid to inflate said vehicle occupant protection device from the stored condition to the inflated condition.

11. Apparatus as defined in claim 10 wherein said first and second end portions of said vehicle occupant protection device are connected to first and second A pillars of the vehicle.

12. Apparatus as defined in claim 11 wherein said inflator is mounted in one of the first and second A pillars.

13. Apparatus as defined in claim 10 wherein said occupant protection device is located in a headliner of the vehicle adjacent the upper portion of the windshield when in the stored condition.

14. Apparatus comprising:

an inflatable vehicle occupant protection device having a stored condition and an inflated condition in which said vehicle occupant protection device extends across an upper portion of a vehicle windshield, said vehicle occupant protection device having first and second end portions located adjacent first and second A pillars of the vehicle when in the inflated condition; and

an inflator for emitting inflation fluid to inflate said vehicle occupant protection device from the stored condition to the inflated condition, said inflator being mounted in one of the first and second A pillars of the vehicle,

said vehicle occupant protection device including first and second tethers extending from said first and second A pillars to said first and second end portions to connect said vehicle occupant protection device to the vehicle.

15. Apparatus as defined in claim 14 wherein one of said first and second tethers is tubular and conducts inflation fluid from said inflator to said vehicle occupant protection device to inflate said vehicle occupant protection device.

16. Apparatus comprising:

a first inflatable occupant protection device having a stored condition and an inflated condition in which said first occupant protection device extends adjacent an upper portion of a vehicle windshield;

a second inflatable occupant protection device having a stored condition and an inflated condition in which said second inflatable occupant protection device extends adjacent a lower portion of the vehicle windshield;

a first inflator for emitting inflation fluid to inflate said first occupant protection device from the stored condition to the inflated condition;

a second inflator for emitting inflation fluid to inflate said second occupant protection device from the stored condition to the inflated condition,

the vehicle having first and second A pillars and said first inflator being mounted in one of the first and second A pillars of the vehicle, said first occupant protection device extending across the upper portion of the windshield when in the inflated condition; and

first and second tethers connecting said first and second end portions of the first occupant protection device to the first and second A pillars.

17. Apparatus as defined in claim 16 wherein one of said first and second tethers is tubular and conducts inflation fluid from said first inflator to said first occupant protection device.

18. Apparatus comprising:

an inflatable vehicle occupant protection device having a stored condition and an inflated condition in which said vehicle occupant protection device extends across an upper portion of a vehicle windshield, said vehicle occupant protection device having first and second end portions, only said first and second end portions of said vehicle occupant protection device being connected to the vehicle when in the inflated condition; and

an inflator for emitting inflation fluid to inflate said vehicle occupant protection device from the stored condition to the inflated condition,

said occupant protection device including first and second tethers extending from said first and second end portions to the vehicle to connect said occupant protection device to the vehicle.

19. Apparatus as defined in claim 18 wherein one of said first and second tethers conducts inflation fluid from said inflator to said vehicle occupant protection device to inflate said occupant protection device.
