Bicyclists helmet with air flow and perspiration control

In a forwardly extending protective helmet having a top and opposite sides, the helmet including a shell and a protective liner in the shell, the combination comprising

• (a) at least two forwardly facing air inlet openings formed in each of said opposite sides of the helmet shell, one of said two openings spaced generally forwardly of the other,
• (b) each of said openings being elongated upwardly and rearwardly and having overall length substantially greater than its width as measured along the major extent of said length,
• (c) each opening defined by and between shell elongated edges one of which substantially throughout its length is spaced closer to the helmet interior than the other edge, said edges extending upwardly and rearwardly to be inclined rearwardly relative to the top of the helmet, and said edges extending in generally parallel relation through their lengths,
• (d) the liner extending into proximity to said edges at the inner side of the shell and forming additional through openings in registration with said openings in the shell.

In a forwardly extending protective helmet, the combination including

• (a) an outer shell containing distributed openings located inwardly of a dome defined by the shell outer surface through which air streams may enter the helmet, said openings defined by transversely elongated, narrow slits of substantially constant width along the lengths of the openings,
• (b) a liner in said outer shell and supporting same near said openings,
• (c) the liner forming left and right air flow channels commuicating with said openings, the channels openly facing the interior of the helmet lengthwise of said channels for conducting air toward the rear of the helmet,
• (d) each slit having two elongated edges, one of which is closer to the helmet interior than the other, the liner forming additional elongated through openings which are in registration with said elongated slits and which are located closer to the helmet interior than said edges, whereby the slit edges are protectively spaced from the helmet interior.
