An overmolded interior vehicle trim panel includes a substrate having a front face and an under face. The under face has a tear seam integrally molded therein to allow an airbag to exit the substrate when the airbag is deployed. The tear seam defines an airbag door. An outer layer is bonded to the front face of the substrate in a mold, thereby forming an overmolded interior vehicle trim panel. The trim panel can include a sheet of hinge material attached to one of the substrate and the outer layer of the overmolded interior trim panel. A portion of the sheet of hinge material defines a hinge member.
