摘要： A helmet principally for use with motorcycles and the like having vent openings on the front thereof. The vent openings are positioned within ram cavities formed between the visor and adjacent guide plates. Passageways extend through attachment mechanisms holding the visor to the helmet. Channels extend through the helmet liner to enhance air flow therethrough. Air ducts may be employed within the channels, providing additional energy absorbing properties to the helmet. Air flow may be further increased by means of a channel extension extending rearwardly from the helmet to advantageously arrange the outlets for maximum flow. An adjustable visor having a transparent visor extension enables selected extension and retraction of the visor to meet road and weather conditions.
