A shaft which pivotally supports a sun visor is formed with flat surfaces at longitudinally staggered positions and on opposite sides of the shaft, a spring is attached to the visor proper which has flat portions for engaging the flat surfaces so that a “snap action”is provided only when the visor is rotated into close proximity of a home position wherein the flat portions of the spring clamp down flatly on the flat surfaces. When the visor is rotated away from this home position the distortion of the flat portions of the spring produces a reaction which induces sufficient friction between the shaft and the spring to hold the visor in any given selected position.

A hinge, comprising: a shaft having a generally circular cross-section; a member rotatably supported on said shaft; indentations defining first and second flat surfaces on said shaft formed along chords of said circular cross-section, said first and second flat surfaces being formed on said shaft at longitudinally staggered positions and on opposite sides of said shaft; and spring means connected to said member for engaging said shaft and for resisting rotation of said member about said shaft, said spring means having resilient first and second flat portions positioned on opposite sides at staggered positions along said spring means for engaging said first and second flat surfaces, respectively, when said member assumes a predetermined angular position with respect to said shaft.
