ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an inflatable vehicle safety apparatus for helping to protect a vehicle occupant in the event of a side impact to a vehicle and/or a vehicle rollover.
BACKGROUND OF THE INVENTION
It is known to inflate a vehicle occupant protection device to help protect a vehicle occupant in the event of a vehicle collision. One particular type of inflatable vehicle occupant protection device is an inflatable curtain that inflates from the roof of the vehicle downward inside the passenger compartment between a vehicle occupant and the side structure of the vehicle in the event of a side impact or rollover. A known inflatable curtain is inflated from a deflated condition by inflation fluid directed from an inflator to the inflatable curtain through a fill tube.
SUMMARY OF THE INVENTION
The present invention relates to an apparatus for helping to protect an occupant of a vehicle that has a side structure and a roof. The apparatus includes an inflatable vehicle occupant protection device that is inflatable away from the vehicle roof into a position between the side structure of the vehicle and a vehicle occupant. An inflation fluid source provides inflation fluid for inflating the vehicle occupant protection device. The vehicle occupant protection device comprises a seam that extends in a spiral-like manner from a location within the boundaries of the vehicle occupant protection device to define a spiral-like chamber portion of the vehicle occupant protection device.
