Motorcycle Helmet

Abstract

The invented appliance is a motorcycle helmet, which makes modifications on current helmet by applying some alteration. This helmet has same appearance as current ones but changing the inner liner structure, altering inner liner material to polyvinyl chloride (PVC) and decreasing the contacting surface between wearer head and the helmet, causing a decrease in temperature and the amount of interior confined heat of the helmet and preventing extra perspiration of wearer by a better ventilation and as a result lead to more efficient motorcycle helmet in comparison with current ones.

1 . A motorcycle helmet, comprising a hard outer shell and an inner liner; wherein said inner liner comprises of an expandable material; an impact absorber installed under said hard outer shell; wherein said impact absorber comprises of distal surface that is in direct contact with a wearer's head and a proximal side connected directly to said hard outer shell; wherein said distal side comprises of multiple primary holes/indentations; wherein said impact absorber further comprises of multiple identical columns located in specific arrangements between said distal surface and proximal side. 
     
     
         2 . The motorcycle helmet of  claim 1 , wherein said expandable material is expandable polystyrene (EPS). 
     
     
         3 . The motorcycle helmet of  claim 2 , wherein said expandable material is completely removable and washable, wherein said expandable material is easily placed back inside said helmet after each wash without losing its integrity or features. 
     
     
         4 . The motorcycle helmet of  claim 1 , wherein said impact absorber comprises polyvinyl chloride (PVC). 
     
     
         5 . The motorcycle helmet of  claim 4 , wherein said columns comprise aerodynamic configuration and allow air flow through said holes. 
     
     
         6 . The motorcycle helmet of  claim 5 , wherein a textile headband comprising of multiple secondary holes is placed under said distal surface. 
     
     
         7 . The motorcycle helmet of  claim 6 , wherein said secondary holes coincide with said primary holes, reducing contact between said wearer's head and said helmet up to 50%; and provide better air flow and ventilation therefore prevent perspiration of said wearer.
