Helmet insert for concussion protection

Abstract

The specification relates to a protection device that includes a helmet and an air sack. The air sack being mounted within the helmet and includes a one-way valve and a snap closure. The one y valve being used for inflation of the air sack and the snap closure being pressure sensitive and releasing pressure within the air sack when impacted by a high load.

1 . A protection device comprising:
 a helmet; and   an air sack, the air sack being mounted within the helmet and capable of being inflated for use, the air sack includes a one-way valve and a snap closure, the one way valve being used for inflation, the snap closure being pressure sensitive and capable of releasing pressure within the air sack when impacted by a high load.   
     
     
         2 . The protection device of  claim 1  wherein the air sack is about 1″ thick, when inflated. 
     
     
         3 . The protection device of  claim 1  wherein the air sack is made of a durable material. 
     
     
         4 . The protection device of  claim 1  wherein the snap closure includes a flap, a male closure and a female closure. 
     
     
         5 . The protection device of  claim 1  wherein the air sack includes arms that fold to the sides of the outer shell. 
     
     
         6 . The protection device of  claim 1  wherein the air sack includes a though hole to remove heat and perspiration. 
     
     
         7 . The protection device of  claim 1  wherein the air sack is lined with a non-absorbent, wicking fabric. 
     
     
         8 . The protection device of  claim 1  wherein the air sack includes a number of through tunnels to act as reinforcing members. 
     
     
         9 . A protection device comprising:
 a helmet; and   an air sack, the air sack being mounted within the helmet and capable of being inflated for use, the air sack including at least two sections being fluidly interconnected through a pressure control mechanism, the pressure control, mechanism capable of releasing pressure from a first section and building pressure in a second section when impacted by a high load.   
     
     
         10 . The protection device of  claim 9  wherein the air pressure within the first section and the second section equalizes when the high load is removed.
