Two sided motorcycle helmet

Abstract

A two sided motorcycle helmet that allows the operator to select between a full open face helmet and a fully enclosed face helmet. With the fully enclosed face orientation, a face shield protects the face of the wearer. With the full open face orientation, the wearer's face is open to the elements. A padding layer is provided on an interior surface of a shell of the helmet. A chin strap is operable to secure the helmet to the wearer's head in either orientation.

What is claimed is: 
     
         1 . A protective helmet comprising:
 a spheroidal shell defining an interior cavity dimensioned to receive a head of a user;   a temporal extension at a medial portion of each of a left side and a right side of the spheroidal shell;   a mandibular guard extending from the temporal extension between a left side and a right side of the spheroidal shell at a first end of the spheroidal shell;   a face shield enclosing a first face opening defined between the mandibular guard, the temporal extension, and a first brow line defined across a first end of the spheroidal shell; and   a second brow line defined at a second end of the spheroidal shell between the temporal extension of the left side and the right side of the spheroidal shell, the second brow line and the temporal extension defining a second face opening.   
     
     
         2 . The protective helmet of  claim 1 , further comprising:
 a chinstrap attached a lower peripheral aspect of the temporal extension; and   a buckle attached to the lower peripheral aspect of an opposite temporal extension.   
     
     
         3 . The protective helmet of  claim 1 , further comprising:
 a protective padding attached to an interior surface of the spheroidal shell.   
     
     
         4 . The protective helmet of  claim 1 , further comprising:
 a vent defined in an intermediate portion of the mandibular guard.   
     
     
         5 . The protective helmet of  claim 1 , further comprising:
 a communications module attached to a lower aspect of the temporal extension.   
     
     
         6 . A protective helmet, comprising:
 a spheroidal shell configured to be reversibly worn on a wearer's head between a first orientation and a second orientation, wherein in the first orientation, a first face opening is enclosed by a protective face shield, and wherein in the second orientation a second face opening is unobstructed.   
     
     
         7 . The protective helmet of  claim 6 , further comprising:
 a temporal extension protruding from a bottom medial section of the spheroidal shell.   
     
     
         8 . The protective helmet of  claim 7 , further comprising:
 a mandibular guard extending from the temporal extension between a left side and a right side of the spheroidal shell.   
     
     
         9 . The protective helmet of  claim 8 , further comprising:
 a padding layer attached to an interior surface of the spheroidal shell.   
     
     
         10 . The protective helmet of  claim 9 , further comprising:
 a chinstrap and cooperating buckle attached to a lower peripheral aspect of the temporal extension between each of the left side and the right side of the spheroidal shell.
