Abstract
A sun visor is provided that includes a core having a periphery that defines an edge of the sun visor. The core comprises a plurality of layers with at least one layer being corrugated. The corrugated layer is characterized by a plurality of alternating ridges and troughs that strengthen the core without adding weight. An upholstery cover is disposed over the core and forms an exterior surface of the sun visor. In one embodiment, the core comprises a plurality of planar and corrugated layers. In another embodiment, the core comprises a rigid panel and a foundation disposed over the panel. The foundation includes a plurality of layers with at least one layer being corrugated to increase the thickness of the core without substantially adding weight to the sun visor.
