This present invention provides a deformable air bag module for use in an instrument panel or door panel of a vehicle. The air bag module has a deformable housing with an inflator and an air bag cushion being disposed within the deformable housing. The module housing has a neck portion defining an opening formed at a first side, wherein the first side is coupled to the instrument panel. The instrument panel includes first and second instrument panel sections and the module housing is disposed about the first and second instrument panel sections so that deployment of the air bag cushion causes deformation of the module housing resulting in the first and second instrument panel sections separating and deployment of the air bag cushion therebetween. When a tear seam is used to define the first and second instrument panel sections, the present invention permits the tear seam to be formed thicker in size and more durable.
