Abstract: An airbag door system is provided comprising a substrate, an outer shell and a foam where all three layers possess a line of mechanical weakness with each line of mechanical weakness at least partially separating each layer into an airbag door portion and a trim member portion. The substrate line of mechanical weakness comprises at least one substrate aperture. The outer shell line of mechanical weakness comprises an outer shell reduced thickness portion defined by an outer shell sever extending partially through an outer shell thickness from an outer shell lower surface towards an outer shell upper surface. The foam line of mechanical weakness comprises a foam reduced thickness portion defined by a foam sever extending partially through a foam thickness from a foam lower surface towards a foam upper surface. The outer shell line of mechanical weakness is displaced relative to a foam line of mechanical weakness.
