Abstract
Abstract Featured for use as a part of an inflator-containing inflatable restraint system is a reaction canister in which the reaction canister body includes a plurality of inflator output treatment fins extending towards, without contacting, the associated inflator. Also, provided are corresponding processes for treating the gas output of a vehicular safety restraint inflator. In practice, such treatment of a contacting stream typically involves one or more of: cooling, redirection of flow, and removal or filtering of particulate therefrom.
