Airbag apparatus
First Claim
1. A vehicle deployable airbag system comprising:
- an inflatable airbag mounted along a roof side of a vehicle cabin and including a gas generator mounting portion having a pair of gas generator inserting ports spaced for a predetermined distance away from one another, and a gas inlet port located between the gas generator inserting ports inside the airbag, an elongated gas generator for generating gas for deploying the airbag, said gas generator including an inflator having a first gas exhaust port formed at one end thereof, an initiator attached to the other end of the inflator, and a casing substantially completely covering the inflator with a gas passage therebetween and having closed ends and a plurality of second gas exhaust ports on its peripheral surface intermediate said closed ends, said gas generator being mounted in said mounting portion such that a substantial portion of the gas generator is located inside the airbag and the closed ends project outwardly through the inserting ports to thereby eject the gas in the inflator from the second gas exhaust ports through the first gas exhaust port at the one end and the gas passage, and annular fastening means tightly fastening the airbag at each of said insertion ports to said gas generator from the outside.

Abstract
To provide an airbag apparatus in which the gas generator can be mounted quite easily to the gas generator mounting portion of the airbag without causing gas leakage at all. A curtain-like airbag having an elongated cylindrical gas generator mounting portion is provided on the upper side surface of the cabin for protecting the passenger of the automotive vehicle. A gas generator insertion port is provided at both ends of the gas generator mounting portion. A gas generator is inserted into the gas generator insertion port, and fastened tightly with a fastener from the outer periphery of the gas generator insertion port. The gas generator is constructed in such a manner that a casing is fitted on a hybrid inflator concentrically with a cylinder and a gas exhaust port is provided on the side peripheral surface of the casing.
