Abstract
A gas generator of an airbag passenger restraint device wherein the gas generator comprises a propellant tube having first and second end closures. The second end closure contains an end cap dual spring subassembly that substantially reduces the vibrations within the generator assembly and propellant. The liberation of fluorocarbons and other undesirable byproducts caused by end cap reactivity is eliminated by employing an inert end cap. By reducing the vibratory effect, inflator performance variability and noise level are substantially reduced.
