A nylon protective cover around the air bag bladder 13 inside the football helmet 4 attaches to the Velcro at four points to the football helmet 4, two on each side.
  • As described in the foregoing paragraphs, the device of this invention comprises a chin strap 1, a helmet 4 comprised of carbon fiber, an air pump valve 8, a polycarbonate military grade face shield 12, an air bag bladder padding 13, and a multi-layer carbon fiber chin guard 14.
  • The air bag bladder padding 13 is attached to the inside shell of the football helmet 4 to protect the head from injury and concussion. The shell of the helmet 4 of this invention is made of a carbon fiber that is very lightweight. This helmet 4 is lighter than a typical football helmet due in part to the lightweight shell of the helmet 4 and the bladder 13, which is filled with air. The helmet 4 has a built in chin guard 14 for added strength. The helmet 4 also has an attachment point for a military grade polycarbonate fiber face shield 12 to protect the user's face. The helmet 4 uses a standard chin strap 1 similar to one manufactured by Shock Doctor. The attachments from the helmet 4 to the padding are with Velcro strips 5 for easy removal. This design of a carbon fiber football helmet 4 with an air bag bladder 13 and a full military grade polycarbonate face shield 12 reduces to total weight by 50 percent and increases visibility. Using an air bladder inside of the helmet 4 greatly reduces the shock to the brain during contact with other players, reducing injuries and concussions.
  • Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations may be made without departing from the spirit and scope of the invention. All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
