An inflation valve assembly, for a dunnage or cargo air bag, comprises an annular flange member which is adapted to be heat-sealed to an interior surface portion of one of the plies of the inflatable bladder of the air bag, and an externally threaded nipple portion for fluidic connection to a source of pressurized fluid for inflating the bladder of the dunnage or cargo air bag. The inflation valve assembly also has a substantially C-shaped upstanding ring member integrally disposed upon the upper surface portion of the annular flange member, and a substantially planar, disc-type flapper valve member, having a substantially circular configuration, has an end portion which is adapted to be fixedly secured upon an arcuate portion of the upper surface portion of the annular flange member by means of a fixation bar which extends along a chordal extent of the annular flange member. Opposite end portions of the fixation bar project radially inwardly toward each other so as to effectively define a pair of oppositely disposed detents for maintaining the flapper valve member in its OPENED state. Accordingly, the height dimension or depth profile of the new and improved inflation valve assembly of the present invention is able to be substantially reduced so as to enable the inflation valve assembly to readily facilitate the sealing of the inflatable bladder during the fabrication thereof.
