Abstract

An inflatable cushion for a side of a vehicle is provided, the inflatable cushion having: a first cushion section formed from a first sheet of material secured to a second sheet of material, the first cushion section having a plurality of separate inflatable cells each of which having an inlet opening for receipt of an inflation gas; an internal passageway formed in the first cushion section, the internal passageway linking and fluidly coupling to each of the plurality of separate inflatable cells via the inlet opening of each of the plurality of separate inflatable cells, the internal passageway being formed by an upper portion of the first sheet of material and an upper portion of the second sheet of material; a fabric diffuser member located in the internal passageway, the fabric diffuser member being sealed at one end and open on another end for receipt of an inflation gas, the fabric diffuser being configured to supply the inflation gas to each of the plurality of separate inflatable cells through a plurality of inflation openings, wherein a height of the fabric diffuser in an inflated configuration is less than a length of the fabric diffuser in the inflated configuration and wherein the fabric diffuser is rolled inwardly to define an un-inflated configuration, the height of the fabric diffuser in the un-inflated configuration being less than the height of the fabric diffuser when it is in an inflated configuration.
