THIS PATENTED airbag modification is easy to add to any new helmet manufacturing process. 

The added cost is not high and may payback by reduced player injury  insurance costs.

Retrofit modification of on-hand helmets, used or new, is an easy field retrofit allowing teams to advance to a much higher level of safety against concussions.

And resulting lower injury cost insurance.

Helmet manufacturers and helmet repair / restoration / refurbishing businesses will find that air bag retrofit modification is a good business model.

Helmets can have the air bag device added while they are in their shop for annual repair / restoration / refurbishing.
