Abstract: The invention pertains to full-face-type helmet windshields, like motorcycle helmet windshields. A modern full-face-type motorcycle helmet, where the windshield is free to be opened and closed as a piece separate from the helmet proper, has a fully open position which stops before the top protective surface or crown area of the helmet, a fully closed position where the windshield rests on the bottom protective surface or chin guard of the helmet, and 1 or more intermediate catches between the fully opened and fully closed positions. At speeds around or above 55 mph the catches do not hold the windshield in place—wind resistance forces it fully open or fully closed. To permit airflow into the helmet and prevent the windshield from being blown completely open or closed an auxiliary prop is required.
