Multi-body helmet construction with shield mounting

Abstract

A helmet can comprise an upper-body and a lower-body nested within the upper-body. An opening can be formed within a front portion of the helmet and disposed between an outer surface of the upper-body and an inner surface of the lower-body. A first magnet can be encased within the upper-body or the lower-body and adjacent the opening. A shield can comprise a shield mount and a second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably coupled to the first magnet. The first magnet and the second magnet can be self-aligned in direct alignment with eyes of a user. A third magnet can be disposed above the first magnet and aligned with the second magnet on an outer surface of the helmet out of sight from eyes of the user.

         21 . A helmet comprising:
 an upper-body comprising an outer shell;   a lower-body comprising an energy absorbing layer nested within the upper body;   an opening formed within a front portion of the helmet;   at least one first magnet encased within the upper-body or the lower-body and adjacent the opening; and   a shield comprising a shield mount and at least one second magnet coupled to the shield mount that is sized to fit within the opening and to be releasably magnetically coupled to the at least one first magnet.   
     
     
         22 . The helmet of  claim 21 , wherein the at least one first magnet comprises a surface that is substantially coplanar with a surface of the opening. 
     
     
         23 . The helmet of  claim 21 , wherein the at least one first magnet and the at least one second magnet are self-aligned with respect to each other such that the shield magnetically couples within the opening in direct alignment with eyes of a user to prevent twisting of the shield while magnetically coupled to the at least one first magnet. 
     
     
         24 . The helmet of  claim 21 , wherein:
 the at least one first magnet comprises:
 a first helmet magnet encased within the upper-body or the lower-body, and 
 a second helmet magnet encased within the upper-body and horizontally offset from the first helmet magnet when the first helmet magnet is encased within the upper body, and the second helmet magnet encased within the lower-body and horizontally offset from the first helmet magnet when the first helmet magnet is encased within the upper body; and 
   the at least one second magnet comprises:
 a first shield magnet coupled to the shield mount, and 
 a second shield magnet coupled to the shield mount and horizontally offset from the first shield magnet. 
   
     
     
         25 . The helmet of  claim 21 , further comprising a third magnet mounted to the upper body above the opening for magnetic coupling with the second magnet. 
     
     
         26 . The helmet of  claim 21 , wherein:
 the at least one first magnet comprises a horizontally elongate shape; and   the at least one second magnet comprises a horizontally elongate shape corresponding to the at least one first magnet to prevent twisting of the shield.   
     
     
         27 . The helmet of  claim 21 , wherein the upper body comprises polycarbonate (PC), polyethylene terephthalate (PET), acrylonitrile butadiene styrene (ABS), polyethylene (PE), polyvinyl chloride (PVC), vinyl nitrile (VN), fiberglass, or carbon fiber. 
     
     
         28 . The helmet of  claim 21 , wherein the lower body comprises expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPTU or EPU), or expanded polyolefin (EPO). 
     
     
         29 . The helmet of  claim 21 , wherein the upper body and lower body are coupled together. 
     
     
         30 . The helmet of  claim 21 , wherein the shield comprises a lens portion.
