Abstract

A wind absorbing and deflecting device attached to the leading strap on a cycling helmet to reduce wind noise while ambient sound passes through to the inner ear so that the user's hearing in not impaired. The device is located in front of the user's ear and against the temple. It is fabricated from faux fur with a pile length of approximately ½ inch and/or soft fleece with a thickness of ¼ to ½ inches. While cycling, the device deflects oncoming wind while the soft fleece and/or faux fur absorbs variable wind gusts and turbulence. The direct wind flow over the ear and particularly over the ear canal is significantly reduced so there is less air pressure variation and less wind noise.

Dependent claims

An apparatus worn on the lead strap of a sport helmet, which passes in front of the ear, for reducing noise caused by wind flowing past the user's ear, the apparatus comprising:

a wind deflector including,
a sound permeable outer portion of fleece or fur configured to partially cover the front part of the ear, said outer portion shaped such that wind flows smoothly over the outer surface and past the ear.
a sound permeable inner portion of fleece or fur attached to the outer portion located alongside the user's face about the ear, said inner portion having a smooth surface flush with the outer surface, closing the gap between the helmet strap and the user's face
a sound permeable outer portion sized to cover the front portion of the ears, leaving the inner and rear portion of the ear exposed to allow ambient sounds to be heard;
and
securing means, located on the outer and inner portion, for securing said wind deflector to the sport helmet strap.
