Abstract: A sun visor assembly which utilizes a plurality of modular visor core components and an outer covering. The visor core components each include an alignment element which cooperates with an alignment element on the outer covering thereby maintaining the visor core components in the proper location. The modularity of the visor core components allows for their use with any one of a plurality of differently configured outer coverings and in a plurality of different visor core component combinations. The modular components include a hinge block for rotatably engaging a visor support rod, a pin section having an exposed support member for supporting a free end of the visor blade and track components for slidingly engaging other components such as a sun visor extension panel.
