Helmet providing improved frontal and peripheral view

The helmet of the present invention comprises an outer and inner shell having a top, a front, a rear, and left and right sides corresponding to wearer's crown, face, rear and left and right sides, respectively. The front of the helmet has an enlarged view window that exposes at least a portion of the wearer's face. The view window has an upper rim, lower rim, right rim, and left rim. The lower rim extends from the front of the helmet to about the auditory canal. The upper rim is separated from the lower rim and loosely tracks the path of the lower rim. The upper rim is connected to the lower rim on both the left and right sides by left and right rims, respectively. A step is formed in the lower rim as it proceeds towards the back of the view window. This increases the wearer's view of the road. The upper rim is connected to the lower rim on both the right and left sides by the right and left side rims, respectively. The side rims have a straight slant that extends backwards from bottom to top. In addition, a portion of the inner padding located on the right and left sides of the helmet is reduced in thickness thereby increasing the peripheral vision of the wearer. The reduced padding also eliminates virtually all blind spots that are associated with conventional helmets. Narrow portions are carved into the outer shell of the helmet starting from left and right rims of the view window and extend to the middle to rear of the helmet. The narrow portions start off deep and gradually resurface at the middle to the rear of the helmet. |

DETAILED DESCRIPTION The inventive helmet solves the above stated problems. The inventive helmet provides a wearer with a greater frontal and peripheral view. This is achieved by a unique structure of the lower and side rims and by narrowing the thickness of the helmet at the side rims at a location near the wearer's eye level. The inventive helmet comprises an outer shell and an inner shell. The front of the helmet has a view window which exposes at least a portion of the wearer's face. The view window is defined by an upper rim, a lower rim, a right rim, and a left rim. The lower rim extends from the front of the helmet to about the wearer's auditory canal. The upper rim is separated from the lower rim and loosely tracks the path of the lower rim. The upper rim is connected to the lower rim on both the right and left sides by the right and left rims, respectively. The lower rim drops in at least a single step fashion at locations substantially below each of the wearer's eyes as it extends towards the rear of the view window. This structural design increases the wearer's frontal field of view without compromising the strength and/or safety of the helmet. The side rims at the rear of the view window are not of the same configuration of the conventional speed helmet. The rear of the view window of conventional speed helmets are rounded. The side rims of the inventive helmet preferably have a straight slant that extends backwards from bottom to top toward the front of the auditory canal and then at about eye level angles forward to the top rim of the view window. Preferably, the deepest portion of the view window is located at approximately the wearer's eye level. Alternatively, the rear of the view window angles straight back. These preferred structures maximize the wearer's view of the road without reducing a large amount of the shell and padding of the helmet. This structural design increases the wearer's frontal and peripheral fields of view. In addition, a portion of the inner padding located on the right and left sides of the inventive helmet is minimally reduced in thickness so as to eliminate any blind spots and increase the wearer's field of view
