Abstract: A system for a vehicle roof, the system includes a roof structure defining a roof opening and a functional type roof assembly, the functional type roof assembly including a functional type panel and an intermediate frame supporting the functional type panel, the intermediate frame having an outer peripheral edge configured to be mounted to the roof structure such that the roof opening is watertightly sealed by the functional type roof assembly, the outer peripheral edge of the intermediate frame having contour features consistent with those of an outer peripheral edge of a standard type panel, the outer peripheral edge of the standard type panel being configured to be mounted to the roof structure when the roof opening is watertightly sealed by the standard type panel in place of the functional type roof assembly.

Abstract: A vehicle structure assembly, including: a first component including a hem structure defining an internal space disposed along an outer edge thereof; and a second component including one of an outer edge and a corresponding hem structure defining a corresponding internal space, wherein the one of the outer edge and the corresponding hem structure defining the corresponding internal space of the second component is adapted to securely engage the hem structure defining the internal space of the first component, thereby joining the second component to the first component. The first component includes a planar body portion and the hem structure includes a retaining arm or flap structure disposed substantially parallel to the planar body portion, wherein the retaining arm or flap structure and the planar body portion are integrally formed and collectively define the internal space.
