Abstract

A headliner assembly covers an inner surface of a motor vehicle roof having a sunroof opening. The headliner assembly includes a dimensionally stable substrate having a first edge extending along the sunroof opening. The substrate has an upper surface facing the inner surface of the motor vehicle roof. The substrate further has a bottom surface opposite the upper surface. A molded reinforcement is fixedly secured to the upper surface of the substrate. The reinforcement has a second edge extending along the sunroof opening. The second edge of the reinforcement has a contoured portion that extends further inwardly toward a center of the sunroof opening relative to the first edge of the substrate. A trim cover has a third edge extending along the sunroof opening. The trim cover is disposed along the bottom surface of the substrate and extends around the contoured portion of the reinforcement so that the third edge of the trim cover is disposed between the upper surface of the substrate and the inner surface of the motor vehicle roof.

Dependent claims

A headliner assembly for covering an inner surface of a motor vehicle roof having a sunroof opening, said headliner assembly comprising:

a dimensionally stable substrate having a first edge extending along the sunroof opening, the substrate having an upper surface facing the inner surface of the motor vehicle roof, the substrate further having a bottom surface opposite the upper surface, the first edge having an outwardly extending tab;
a molded reinforcement fixedly secured to the upper surface of the substrate, the reinforcement having a second edge extending along the sunroof opening, the second edge of the reinforcement having a contoured portion having an outer surface with an arcuate cross section, the contoured portion extends further inwardly toward a center of the sunroof opening relative to the first edge of the substrate, the reinforcement includes an undercut adjacent the contoured portion and a recess, the recess receives the outwardly extending tab of the first edge to retain the first edge along the undercut to provide a smooth transition between the substrate and the contoured portion;
and
a trim cover having a third edge extending along the sunroof opening, the trim cover disposed along the bottom surface of the substrate and extending around the contoured portion of the reinforcement such that the third edge of the trim cover is disposed between the upper surface of the substrate and the inner surface of the motor vehicle roof.
