摘要： Components of a vehicle airbag gas generator, or inflator, are coated with reactivity resistant materials to protect them from deterioration caused by contact with the high temperature, reactive gases generated by recently developed non-azide high reactive temperature gas generating materials. Suitable coatings include those produced from ceramics and reactivity resistant metals. These coatings also provide long term protection of the components from deterioration caused by the environment/atmosphere within the inflator.

摘要： A gas generating inflator assembly for a vehicle safety restraint system including an inflator housing having two walls, an inner wall and an outer wall. The inner and outer walls form a combustion chamber therebetween. A filter pack is disposed within the combustion chamber along an inner diameter of the outer wall. Gas generant is also disposed within the combustion chamber. An internal structure is disposed within the combustion chamber for diffusing the ignitor blast and retaining slag produced by the ignited gas generant. The internal structure is spaced from the filter pack and the inner wall such that a portion of the gas generant is located between the internal structure and the inner wall and another portion of the gas generant is located between the internal structure and the filtration pack. The internal structure can be a ring of solid material, an expanded metal material or screen, a star-shaped configuration having a plurality of portions contacting an inner diameter of the filter pack, or a solid metal structure which may include an internal porous structure screen of wire mesh or expanded metal attached thereto.

摘要： 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.
