Vehicle Safety Device with Intumescent Material

Abstract

An inflator comprises a housing having a base, a wall extending from the base, and an inner volume at least partially defined by the base and the wall. A pyrotechnic gas generant material is disposed within the inner volume and an intumescent material is also disposed within the inner volume. The base may have an inner surface and an outer surface, and the wall may also have an inner surface and an outer surface. The inner surface of the base and the inner surface of the wall face the inner volume. The intumescent material may be in contact with the inner surface of the base and/or the inner surface of the wall. Alternatively, the intumescent material may be disposed outside the inner volume and may be in contact with the outer surface of the base and/or the outer surface of the wall. An airbag module may include the inflator.
