Abstract
An igniter for a passenger vehicle safety airbag module includes a housing with apertured walls, gas-generating tablets filling the housing, and, in direct contact with gas-generating tablets, an initiator containing combustible material. A plurality of four malleable flaps of substantially identical shape and size are secured about the squib in an upstanding circumscribing array with spaced-apart, opposed lateral edges between adjacent of the flaps interconnected by fluid seals in the form of webbing that is structurally less robust than the flaps. The ends of the flaps remote from the squib curl radially inwardly into a spaced-apart edge-to-edge disposition beyond the combustible material. The webbing and the flaps together enclose an interior space and the combustible material. Pressure from the ignition of the combustible material causes the fluid seals to burst and the flaps to pivot outwardly crushing the gas-generating tablets in the housing.
