  • Patent number: 4591956
    Abstract: A sun visor for an automotive vehicle having a swivel bearing at one upper longitudinal edge region. The swivel bearing includes a non-metallic, plastic bearing part having a bearing borehole for the metallic sun-visor shaft and a parallel plug opening for an electric contact element. The electric contact element in the plug opening is connected to one of the wires from the light source which illuminates the mirror on the sun-visor body. A passage channel between the bearing borehole and the plug opening has a contact projection on the contact element biased through it to project into the bearing borehole and contact the shaft therein. The shaft has a recess extending partially around it at a region along it such that the contact projection will or will not make electric contact with the visor shaft depending upon the swivel position of the visor body.
