Abstract
An airbag device for use with a vehicle door having a window, the airbag device comprising: an inflatable cushion having a predetermined shape, the predetermined shape being configured to have a periphery larger than the periphery of the window of the door when the inflatable cushion is inflated; a backing plate for mounting the inflatable cushion in a desired location, the backing plate providing a reaction surface for a portion of the inflatable cushion as it is being inflated; an inflator for providing an inflation output to the inflatable cushion; and a conduit for providing fluid communication between the inflator and the inflatable cushion, the conduit having a diffuser portion disposed within the inflatable cushion, the diffuser portion having a plurality of diffuser openings for allowing the inflation output to be received within the inflatable cushion, wherein inflation of the inflatable cushion by the inflator will cause portions of the inflatable cushion to overlap the periphery of the window opening such that a retentive covering is provided over the window.
