Abstract
Provided is an inflator for providing propellant gases to inflate a bag of an automotive safety system for restraining an occupant of a vehicle in which the inflator is a pure pyrotechnic inflator that generates propellant gases that are substantially free of metal-containing particulate and condensable materials without requiring storage of a pressurized gas. The propellant gases are generated from a solid gas-generating propellant composition including two components. A first component is fuel-rich and has a fast burn rate. The second component is a oxidizer that, although having a slow burn rate, operates in combination with the first component at an acceptably fast burn rate to oxidize carbon monoxide and/or hydrogen produced during combustion of the first component to carbon dioxide and/or water, respectively.
