Abstract

Aspects of the present disclosure provide a helmet including customized helmet layers and corresponding methods of construction. In one aspect, a method comprises capturing a 3D image of a head corresponding to the head of an individual, and rendering a 3D headform based on the 3D image. A lining layer is formed, which includes a geometry corresponding to the 3D headform and the inner surface of the shell layer such that an inner surface of the lining layer conforms to the shape of a corresponding portion of the 3D headform. An outer surface of the lining layer further conforms to the shape of a corresponding portion of an inner surface of a shell layer. Another aspect of the method comprises forming a shell layer such that the shell layer includes a geometry corresponding to the shape of a portion of the 3D headform.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A helmet comprising:
 a first shell layer including a first geometry such that the shape of an inner surface of the first shell layer corresponds to the shape of a portion of the head of a user; and   a lining layer coupled to the inner surface of the first shell layer, wherein the lining layer comprises a substantially uniform thickness and includes a second geometry corresponding to the portion of the user's head and the inner surface of the first shell layer such that:
 an inner surface of the lining layer conforms to the shape of the portion of the user's head, and 
 an outer surface of the lining layer conforms to the shape of a corresponding portion of the inner surface of the first shell layer. 
   
     
     
         2 . The helmet of  claim 1  further comprising a second shell layer coupled to the first shell layer, wherein the second shell layer includes a third geometry such that the shape of a portion of an inner surface of the second shell layer corresponds to the shape of a portion of an outer surface of the first shell layer. 
     
     
         3 . The helmet of  claim 2 , wherein the outer surface of the first shell layer does not correspond to the shape of the portion of the head of the user. 
     
     
         4 . The helmet of  claim 2 , wherein the outer surface of the first shell layer corresponds to the shape of the portion of the head of the user. 
     
     
         5 . The helmet of  claim 2 , wherein the second shell layer is coupled to the first shell layer through a shear mechanism allowing the second shell layer to slide relative to the first shell layer, wherein the shear mechanism includes an energy transformer having an absorptive or dissipative material. 
     
     
         6 . The helmet of  claim 2 , further comprising a third shell layer coupled to the second shell layer, wherein the third shell layer includes a fourth geometry such that the shape of a portion of an inner surface of the third shell layer corresponds to the shape of a portion of an outer surface of the second shell layer. 
     
     
         7 . A helmet comprising:
 a first shell layer including a first geometry such that the shape an inner surface of the first shell layer corresponds to the shape of a portion of a digital 3D headform; and   a lining layer coupled to the inner surface of the first shell layer, wherein the lining layer comprises a substantially uniform thickness and includes a second geometry corresponding to the portion of the digital 3D headform and the inner surface of the first shell layer such that:
 an inner surface of the lining layer conforms to the shape of the portion of the digital 3D headform, and 
 an outer surface of the lining layer conforms to the shape of a corresponding portion of the inner surface of the first shell layer. 
   
     
     
         8 . The helmet of  claim 7 , wherein the digital 3D headform corresponds to the head of a user. 
     
     
         9 . The helmet of  claim 8 , wherein the digital 3D headform is rendered from a 3D image of the head of the user and modeled to remove or flatten hair. 
     
     
         10 . The helmet of  claim 7  further comprising a second shell layer coupled to the first shell layer, wherein an inner surface of the second shell layer includes a third geometry such that the shape of an inner surface of the second shell layer corresponds to the shape of a portion of an outer surface of the first shell layer. 
     
     
         11 . The helmet of  claim 10 , wherein the outer surface of the first shell layer does not correspond to the shape of the portion of the digital 3D headform. 
     
     
         12 . The helmet of  claim 10 , wherein the outer surface of the first shell layer corresponds to the shape of the portion of the digital 3D headform. 
     
     
         13 . The helmet of  claim 10 , wherein the second shell layer is coupled to the first shell layer through a shear mechanism allowing the second shell layer to slide relative to the first shell layer, wherein the shear mechanism includes an energy transformer having an absorptive or dissipative material. 
     
     
         14 . The helmet of  claim 10 , further comprising a third shell layer coupled to the second shell layer, wherein the third shell layer includes a fourth geometry such that the shape of a portion of an inner surface of the third shell layer corresponds to the shape of a portion of an outer surface of the second shell layer. 
     
     
         15 . Protective gear comprising:
 a first shell layer including a first geometry such that the shape an inner surface of the first shell layer corresponds to the shape of a portion of the head of a user; and   a lining layer coupled to the inner surface of the first shell layer, wherein the lining layer comprises a substantially uniform thickness and includes a second geometry corresponding to the portion of the user's head and the inner surface of the first shell layer such that:
 an inner surface of the lining layer conforms to the shape of the portion of the user's head, and 
 an outer surface of the lining layer conforms to the shape of a corresponding portion of the inner surface of the first shell layer. 
   
     
     
         16 . The protective gear of  claim 15  further comprising a second shell layer coupled to the first shell layer, wherein the second shell layer includes a third geometry such that the shape of a portion of an inner surface of the second shell layer corresponds to the shape of a portion of an outer surface of the first shell layer. 
     
     
         17 . The protective gear of  claim 16 , wherein the outer surface of the first shell layer does not correspond to the shape of the portion of the head of the user. 
     
     
         18 . The protective gear of  claim 16 , wherein the outer surface of the first shell layer corresponds to the shape of the portion of the head of the user. 
     
     
         19 . The protective gear of  claim 16 , wherein the second shell layer is coupled to the first shell layer through a shear mechanism allowing the second shell layer to slide relative to the first shell layer, wherein the shear mechanism includes an energy transformer having an absorptive or dissipative material.
