A sun visor for an automotive vehicle, having one main surface in which is defined a recess in which a housing is disposed over which a cover is pivotally mounted. One hinge pin for the cover is placed on the visor body. A second hinge pin for the cover is placed on the cover. A C-shaped strap joins the hinge pins. Each end region of the strap has two detent recesses. A respective spring biased locking element at each end region engages in one or the other respective recess at the end region to hold the strap to pivot between two detented positions. This holds the cover and also permits the cover to pivot between detented positions, which enables the cover to be held closed against the one main surface, outwardly projecting from that surface or fully opened orientation at that surface. Details of both spring arrangements for cooperating with the detent recesses are disclosed. The side of the cover exposed at a fully open orientation carries a mirror.
