    摘要: A sun visor for automotive vehicles having a flat, generally rectangular, sun-visor body on which is provided in one corner a mounting bracket. The bracket may be formed by plastic injection molding and includes a mounting borehole for receiving one end region of a sun-visor shaft. The bracket supports a U-shaped leaf spring located in the borehole which radially clamps the end region of the sun-visor shaft. The arms of the spring are placed in recesses which are formed in the wall of the mounting borehole. The leaf spring is located within an insertion opening which is defined at one end of the mounting borehole. The insertion opening and the leaf spring located there are enclosed by a closure element.

    摘要: 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. Then the mounting shaft is inserted into the insertion opening. The integral extension can also serve as an anchor for clamping the bracket in place during the foaming of the sun visor body.
