Abstract: A protective helmet for use by the riders of motorcycles and the like is disclosed, characterized by the provision of a visor which is pivotally connected with the helmet by pivot means contained solely within the interior of the helmet. In a preferred embodiment, the helmet comprises a shell including separate, superimposed body and cover portions each containing a window opening, the cover portion being connected with and spaced from the body portion to define a space for receiving the visor when the visor is pivoted about a horizontal pivot axis from the closed protective position toward an open position relative to the window opening. In a alternate embodiment, the visor is generally cylindrical and fits within a pair of oppositely disposed guides extending continuously around the horizontal inner circumference of the shell above and below the window opening, respectively, whereby the visor pivots about a vertical pivot axis.
