  • Patent number: 4610477
    Abstract: A sun visor for automotive vehicles with one or more mounting brackets which are formed within the body of the sun visor. The sun visor is a molded foam body rigidified by a reinforcing insert. The mounting brackets for the visor are preferably formed by plastic injection molding, and the visor body is formed by foaming over the insert and the brackets. The mounting brackets each have at least one insertion opening which accommodates a respective mounting shaft or pin for connecting the sun visor to the body of the vehicle. To prevent foaming material from entering into a bracket insertion opening during the production of the sun visor, the mounting brackets are formed with an integral extension surrounding the area of the insertion opening. The integral extension protrudes out of the region of the sun visor body being foamed. After the foaming step in the manufacturing of the sun visor is completed, the integral extension is removed from the mounting bracket.
