Abstract
Abstract A motorcycle helmet having a modified exterior configuration to attenuate noise generated when passing through the air. The modified helmet begins flaring outwardly from the traditional helmet configuration at a point adjacent to the chin of the wearer, terminates at a location generally behind the ear of the wearer and is spaced from the exterior shell of the helmet at the central portion of the rearward edge. The trailing edge of the sound attentuating device is open so that the wearer retains the ability to hear noises from behind and beside him.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
An attachment for motorcycle helmets or the like, comprising: a pair of similar premolded outwardly flaring, contour changing members, one to be attached to each side of the preformed helmet shell, each of said members configured such that the interior peripheral surface around a majority of the members conforms to the helmet surface and is adapted to be sealingly secured thereagainst and having an exterior surface that smoothly flows from a foremost position adjacent the chin of a wearer whereat it is relatively shallow and narrow to a rearwardmost position generally covering the ear of the wearer, spaced from the helmet surface and extending from adjacent the bottom of the helmet to a position generally above and behind the ear of the wearer.
Claim 2
Dependent Claim
123 words
An attachment for motorcycle helmets or the like, comprising: a pair of similar premolded outwardly flaring, contour changing members, one to be attached to each side of the preformed helmet shell, each of said members configured such that the interior peripheral surface around a majority of the members conforms to the helmet surface and is adapted to be sealingly secured thereagainst and having an exterior surface that smoothly flows from a foremost position adjacent the chin of a wearer whereat it is relatively shallow and narrow to a rearwardmost position generally covering the ear of the wearer, spaced from the helmet surface and extending from adjacent the bottom of the helmet to a position generally above and behind the ear of the wearer.
Claim 3
Dependent Claim
122 words
A motorcycle helmet which reduces the noise created by passing wind without lessening the ability of a rider to hear comprising: a rigid exterior shell approximating the shape of a wearers head and including the necessary padding or other attachments to provide safety and comfort, outwardly extending helmet configuring elements extending along each side of the helmet and forming a smooth surface therealong, said elements forming a contoured smoothly flowing leading portion which extends rearwardly while simultaneously becoming more prominent along the horizontal and vertical dimensions of the helmet and terminating at a position normally behind the ear of the wearer in a flared open condition generally reducing noise created while passing through the wind and yet permitting entry of traffic noise.
Claim 4
Dependent Claim
122 words
A motorcycle helmet which reduces the noise created by passing wind without lessening the ability of a rider to hear comprising: a rigid exterior shell approximating the shape of a wearers head and including the necessary padding or other attachments to provide safety and comfort, outwardly extending helmet configuring elements extending along each side of the helmet and forming a smooth surface therealong, said elements forming a contoured smoothly flowing leading portion which extends rearwardly while simultaneously becoming more prominent along the horizontal and vertical dimensions of the helmet and terminating at a position normally behind the ear of the wearer in a flared open condition generally reducing noise created while passing through the wind and yet permitting entry of traffic noise.
Claim 5
Dependent Claim
19 words
An attachment as in claim 1, wherein the interior of the contour changing members includes a sound absorbing material.
Claim 6
Dependent Claim
26 words
An attachment as in claim 1, wherein the helmet does not extend over the chin and the attachment is secured adjacent the lowermost front edge thereof.
Claim 7
Dependent Claim
26 words
An attachment as in claim 1, wherein the elements includes relatively flat edges to conform to and be adhesively attached to the exterior of the helmet.
Claim 8
Dependent Claim
19 words
An attachment as in claim 2, wherein the interior of the helmet configuring elements includes a sound absorbing material.
