`ABSTRACT
`Airbag inflator system includes an inflatable airbag, e.g., a
`:::1:n;:::::;a:1:«E:1%; tzehsszzzzsg :0§::n:::::';“;§::::I:
`conduit leading from the gas generating system to the housing
`to provide gas to the housing, e.g., to a lateral end of the
`hous1ng.A filter may be arranged between the gas generating
`system and the housing, possibly in the conduit. A nozzle may
`be arranged between the gas generating system and an interior
`ofthe airbag, which nozzle is varied as a function oftempera-
`ture. The housing may be movably arranged relative to a fixed
`base and mounted to vary its relation to the base as a function
`oftemperature, e.g., via elastic or deformable supports which
`support the housing on the base.

`
`FIELD OF THE INVENTION
`
`[0003] The present invention relates to side curtain airbags
`with an associated inflator.
`
`BACKGROUND OF THE INVENTION
`
`[0004] Background of the invention is set forth in the ’623
`application, in particular at sections 2.1, 2.2 and 2.3, and the
`definitions in section 5 thereof are applicable herein.
`[0005] All mentioned patents, published patent applica-
`tions and literature are incorporated by reference herein.
`
`OBJECTS AND SUMMARY OF THE
`INVENTION
`
`It is an object of the present invention to provide a
`[0006]
`new and improved side curtain airbag system with an associ-
`ated inflator. Other objects and advantages of the present
`invention will become apparent from the following descrip-
`tion of the preferred embodiments taken in conjunction with
`the accompanying drawings, and some are also set forth in the
`parent ’623 application.
`[0007]
`In order to achieve this object and possibly others,
`an airbag inflator system in accordance with the invention
`includes an inflatable airbag, e.g., a side curtain airbag, a
`housing, a gas generating system arranged apart from the
`housing for generating gas, and a conduit leading from the gas
`generating system to the housing to provide gas to the hous-
`ing, e.g., to a lateral end of the housing. A filter may be
`arranged between the gas generating system and the housing,
`possibly in the conduit. A nozzle may be arranged between
`the gas generating system and an interior ofthe airbag, which
`nozzle is varied as a function of temperature. The housing
`may be movably arranged relative to a fixed base and
`mounted to vary its relation to the base as a function of
`temperature, e.g., via elastic or deformable supports which
`support the housing on the base. When the housing defines a
`chamber containing generated gas, the properties of a conduit
`between the chamber and the interior of the airbag can be
`varied as function of the pressure in the chamber.
`
`[0008] A method for inflating an airbag in accordance with
`the invention includes generating gas at a location apart from
`housing, directing the gas through a conduit into the housing
`and directing the gas from the housing into the airbag. Fur-
`ther, it is possible to vary a conduit between the housing and
`the airbag as a function of temperature to thereby provide
`variable amounts of gas to the airbag as a function of tem-
`perature. The variation of the conduit may be automatic and
`obtained via appropriate construction of the inflator assem-
`bly. The conduit may pass into only one lateral end of the
`housing.
