Abstract
The present invention is directed to the use of protective layers on or adjacent to interior surfaces of the metal housings of gas generators, or inflators, used in automotive airbag systems. The protective layers are provided to protect such housings from deterioration which might otherwise be caused by impingement of the high temperature and chemically reactive generated gases and other associated reaction products on the interior surfaces of the housing. The protective layers can be in the form of coatings or platings on the housing surface or they can be provided as separate structures which shield specific portions of the housing's interior surfaces. The invention is particularly useful in protecting aluminum housings when they are used with the newer high reaction temperature non-azide gas generant materials.
