Airbag inflator system includes an inflatable airbag, a flexible housing, and a gas generating system for generating gas which is directed from the housing to the interior of the airbag. The housing may be made by an extrusion process to provide it with its flexible cl of plastic. An aspirating structure or nozzle may be arranged between the gas generating system and an interior of the airbag, which nozzle is varied as a function of temperature. The aspirating structure or arrangement enables air from the passenger compartment of the vehicle to mix with the generated gas prior to being directed into the airbag.

The invention claimed is: 1. An airbag inflator system for a vehicle, comprising: an inflatable, side curtain airbag arranged to be mounted to an upper portion of a frame of a vehicle and to inflate in a generally downward direction from its mounting location to a position along a left or right side of the vehicle; said side curtain airbag, when uninflated, forming an elongate structure extending above at least a portion of a first window, at least a portion of a second window, and a pillar separating the first and second windows along the left or right side of the vehicle; a gas releasing system comprising an elongate housing operative for releasing gas which is directed from said housing to an interior of said side curtain airbag, said housing containing a system for generating gas or storing compressed gas that is released to flow into said side curtain airbag in order to inflate said side curtain airbag to protect a first occupant seated next to the first window and a second occupant seated next to the second window in the response to a detected crash involving the vehicle; and wherein said housing of said gas releasing system is spaced apart from said side curtain airbag, further comprising a tube operatively connecting said housing to said side curtain airbag and through which the released gas from said housing is directed into said side curtain airbag. 2. A vehicle including a roof rail and the system of claim 1, said housing being mounted to said roof rail. 3. The system of claim 1, wherein said housing is curved. 4. The system of claim 1, wherein said housing is made of plastic. 5. The system of claim 1, further comprising an aspirating structure or arrangement for enabling air from the passenger compartment of the vehicle to mix with the released gas prior to being directed into said side curtain airbag. 6. The system of claim 5, wherein said aspirating structure or arrangement is arranged at one end of said housing. 7. The system of claim 1, wherein said housing is flexible. 8. The system of claim 1, further comprising a nozzle between said gas releasing system and an interior of said side curtain airbag, a size of said nozzle being varied as a function of temperature. 9. The system of claim 1, wherein said housing is movably arranged relative to a fixed base and mounted to vary its relation to said base. 10. The system of claim 9, further comprising elastic supports for supporting said housing on said base. 11. The system of claim 9, further comprising temperature-deformable supports for supporting said housing on said base. 12. The system of claim 1, wherein said housing defines a chamber containing compressed gas, the properties of a conduit between said chamber and the interior of said side curtain airbag being varied as function of the pressure in said chamber. 13. A method for inflating a side curtain airbag in a vehicle, comprising: mounting an inflatable side curtain airbag to an upper portion of a frame of a vehicle, wherein the side curtain airbag, when uninflated, forms an elongate structure extending above at least a portion of a first window, at least a portion of a second window, and a pillar separating the first and second windows along the left or right side of the vehicle; arranging the side curtain airbag to inflate in a generally downward direction from its mounting location to a position along a left or right side of the vehicle; mounting a gas releasing system to the upper portion of a frame of a vehicle, wherein the gas releasing system comprises an elongate housing containing a system for generating gas or storing compressed gas which is directed from the housing to an interior of the side curtain airbag to inflate the side curtain airbag; spacing the elongate housing of the gas releasing system apart from the side curtain airbag; connecting a tube between the housing and the airbag through which the released gas is directed from the housing into the airbag; detecting a crash involving the vehicle using a crash sensor system; and releasing the compressed gas from the housing to inflate the side curtain airbag to protect a first occupant seated next to the first window and a second occupant seated next to the second window in response to the detected crash. 14. The method of claim 13, further comprising forming the housing by an extrusion process. 15. The method of claim 13, further comprising forming the housing from plastic. 16. The method of claim 13, further comprising enabling air from the passenger compartment of the vehicle to mix with the released gas prior to being directed into the side curtain airbag. 17. The method of claim 13, further comprising varying a conduit between the housing and the side curtain airbag as a function of temperature to thereby provide variable amounts of gas to the side curtain airbag as a function of temperature. 18. A method for protecting an occupant of a vehicle in the event of an accident involving the vehicle, wherein the step of detecting a crash involving the vehicle using a crash sensor system comprises determining, using a processor, when the vehicle is about to be or in an accident for which inflation of the airbag is necessary, the method comprising: mounting the side curtain airbag and the housing to a roof rail of the vehicle; and when inflation of the airbag is determined by the processor to be necessary, inflating the airbag in accordance with the method of claim 13, such that when inflated, the airbag deploys downward to a position along the left or right side of a frame of the vehicle.
