A generant assembly within the inflator housing includes cylindrical filter having first and second ends enclosing a gas generant. A cup-shaped first end base has a circular main body closing the first end of the inflator housing. A cylindrical outer wall surrounds the first end of the filter and is enclosed within the sidewall of the inflator housing. A cylindrical inner wall extends from the main body parallel to the outer wall. A pre-load member is intermediate and is compressed between the inner wall and gas generant.
