Abstract
An air bag inflator (22) includes a container (40) and an initiator (42). The container (40) defines a storage chamber (50) containing inflation fluid at an elevated pressure. A container wall (46) has a frusto-conical surface (154) defining a passage (156) extending outward from the storage chamber (50) through the container wall (46). The initiator (42) extends into the storage chamber (50) through the passage (156) in the container wall (46), and has a frusto-conical peripheral surface (88). The frusto-conical surfaces (88,154) are pressed tightly against each other in sealing contact so as to block the inflation fluid from leaking outward through the passage in the container wall (46).
