Abstract
A diffuser (18) defines a plenum (50) containing an inflator (16). The diffuser (18) has diffuser walls (94,96) with inflation fluid outlet openings (100) extending outward from the plenum (50), and further has first and second clamping walls (110,112) facing in opposite directions across the plenum (50). The first clamping wall (110) is bendable pivotally inward across the plenum (50). A load bearing structure that includes two locking tabs (120,122) and a fastener (126) maintains the first clamping wall (110) under a bending load. The bending load urges the first clamping wall (110) pivotally inward across the plenum (50) so as to clamp and retain the inflator (16) tightly between the clamping walls (110,112).
