  • Patent number: 4944549
    Abstract: A sun visor for a motor vehicle comprising a sun visor body developed as a cushioning body embedded in a covering formed from two precut sheets which are welded around the circumference to each other by high frequency welding. A stiffening reinforcement insert is disposed within the cushioning body. A swing mounting pin is formed on the reinforcing insert generally inward from the upper circumferential edge of the visor body. That pin has two diametrically opposite either axially extending flats or groove shaped depressions. The flat or depressions prevent a buildup of the weld beads produced upon the high frequency welding. There are at least two radially protruding, axially extending ribs defined on the mounting pin which penetrate into the covering material and prevent relative movement therebetween. The mounting shaft for the visor body extends into a mounting housing and the mounting shaft and the swing mounting pin are axially aligned.
