Abstract
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. A 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 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.
