摘要： A canister endwall for use as part of a reaction canister of an airbag module for securing an airbag inflator. The airbag inflator has a cylindrical inflator sidewall of a predetermined diameter that ends in a tapered portion of the inflator sidewall that tapers radially inwardly to one end of the airbag inflator having an inflator flange. The inflator flange extends radially outwardly from the tapered portion of the inflator sidewall but has a diameter that is smaller than the diameter of the inflator sidewall. The canister endwall has an inner edge defining an airbag inflator mounting hole and a truncated conical array of a plurality of resilient fingers extending from the inner edge. The inner edge of the canister endwall is sized and shaped to allow passage of the inflator flange of the airbag inflator and engage the tapered portion of the inflator sidewall in a substantially gas-tight manner, and the truncated conical array of the plurality of resilient fingers is sized to butt against the inflator flange when the tapered portion of the inflator sidewall is engaged with the inner edge. The plurality of resilient fingers are bendable to allow passage of the inflator flange and, once the inflator flange passes through the truncated conical array of the plurality of resilient fingers, to spring back and butt against the inflator flange to prevent the inflator flange from being pulled out of the airbag inflator mounting hole.
