  • Publication number: 20080178532
    Abstract: A seal mounting flange projects from automotive body structure into a door opening and receives a U-shaped base portion of a seal that seals with the periphery of an automotive door. The U-shaped base portion has ribs extending therefrom that function as barbs which engage the flange or engage a ramp or bead on the flange to prevent the seal from being dislodged from the door opening. The seal includes a pair of joined tubular portions that are relatively flexible and are flattened upon closing the door to seal with the door.

  • Patent number: 5304273
    Abstract: The present invention provides a new and improved method for manufacturing vehicle interior trim panels such as door panels and instrument panels in which different regions of the trim panel have different colors or other aesthetic characteristics. Two pieces of sheet vinyl having the desired color or other aesthetic characteristic desired in the manufactured trim panel are cut to shape and then bonded together edge-to-edge to form a composite two-tone vinyl sheet. This composite vinyl sheet is draped over a mold having a blade projecting from the mold surface. A retainer is installed onto the backside of the composite vinyl sheet to attach the composite vinyl sheet to the blade and thereby hold the vinyl in place with the bond between the two sheets located at the apex of the blade. The mold is closed and urethane is poured against the backside of the composite vinyl sheet to encapsulate the retainer.
