Abstract
Abstract A bicyclist's helmet comprises: (a) an outer shell containing distributed openings through which air streams may enter the helmet, (b) a liner in said outer shell and supporting same adjacent such openings, (c) the liner forming left and right air flow channels communicating with the openings, the channels openly facing the interior of the helmet lengthwise of the channels for conducting air toward the rear of the helmet. In addition, a screen may be located over at least one of the channels; the openings may be transversely elongated and have narrow slit width to increase air pickup yet maintain helmet strength; a removable brow perspiration pad may be employed inwardly of a frontal opening in the helmet; an adjustable visor may be incorporated in the helmet; and a quickly attachable and detachable connection may be employed on the helmet retention system.
