ABSTRACT:
A helmet has an outer shell with a front viewing opening, and a visor swingable between up and down positions. The helmet also includes structure mounting the visor to swing between such positions, and detent structure on one arm portion of a ratchet plate to retain the visor in such positions. The detent structure includes shoulders to lock the visor in at least one of such positions, and to allow easy unlocking by manual deflection of a portion of the visor, away from the shell. The ratchet plate also has a second arm portion attached to an inwardly recessed section of the shell, so that the visor is swingable in closely spaced relation to the shell outer front surface.
