An improved protective shell for a helmet, where the shell has angled panels forming pyramid-like surface structures covering the surface of the helmet. Each pyramid-like structure has three or more panels conjoining to form an apex. In one embodiment, each of the panels is a triangle having a base and a point that conjoins adjacent panels, thereby forming the apex. The limited number of apex points and the orientation of the angled panels reduce the probability that an impacting object will deliver a square blow to the helmet. The probability is increased that such blows will be only glancing in nature, thereby reducing the severity of the blow and head injury to the wearer.

1. A protective helmet comprising: an outer shell having an outside surface, an inside surface, and a plurality of surface pyramids disposed on the outside surface, each pyramid comprising three or more panels, each panel having a base and a point, wherein in each pyramid the points of the panels conjoin at the apex of the pyramid, and there are three holes in the outer surface of the outer shell wherein each hole is formed in an apex of the pyramid and the hole passes through the outer shell; andan inner shell disposed inside the protective helmet and spaced apart from the outer shell such that the space between the outer shell and the inner shell forms an air cushion layer;wherein the outside surface of the outer shell is configured to deflect the impact force caused by objects striking the protective helmet, and the three holes on the outer surface are configured to permit ingress and egress of air to and from the air cushion layer, a damping effect of said air cushion layer being reduced or increased;wherein the three holes reduce said impact force; andwherein the radius of each of said apex shell is raised a sufficient distance from its base such that said panels create a raised outside surface of said outer shell. 2. The helmet of claim 1, wherein the inside surface of the outer shell is contoured to match the pyramid contours of the outside surface, and the inner shell comprises a top surface having contours configured to mate with the contours of the inside surface of the outer shell. 3. The helmet of claim 1, wherein a plurality of pyramids comprise a plurality of holes disposed in the apexes of the plurality of the pyramids, each hole disposed in fluid communication with the air cushion layer such that the hole permits ingress and egress of air to and from the air cushion layer. 4. The helmet of claim 2, wherein a plurality of pyramids comprise a plurality of holes disposed in the apexes of the plurality of the pyramids, each hole disposed in fluid communication with the air cushion layer such that the hole permits ingress and egress of air to and from the air cushion layer. 5. The helmet of claim 1, wherein the outer shell comprises at least one three-sided pyramid. 6. The helmet of claim 2, wherein the outer shell comprises at least one three-sided pyramid. 7. The helmet of claim 3, wherein the outer shell comprises at least one three-sided pyramid. 8. The helmet of claim 2, wherein the outer shell comprises at least one four-sided pyramid. 9. The helmet of claim 3, wherein the outer shell comprises at least one four-sided pyramid. 10. The helmet of claim 4, wherein the outer shell comprises at least one four-sided pyramid. 11. A protective helmet comprising: an outer shell having an outside surface, an inside surface, and three or more flat surface panels disposed on the outside surface of the outer shell, the three or more panels conjoining at a common point, each of said three or more panels being oriented in a different plane such that the common point forms an apex in relation to the conjoining three or more panels, and, there are three holes in the outer surface of the outer shell wherein each hole is formed in an apex of the pyramid and the hole passes through the outer shell; andan inner shell disposed inside the protective helmet and spaced apart from the outer shell such that the space between the outer shell and the inner shell forms an air cushion layer;wherein the outside surface of the outer shell is configured to deflect the impact force caused by objects striking the protective helmet, and the three holes in the outer surface are configured to permit ingress and egress of air to and from the air cushion layer, a damping effect of said air cushion layer being reduced or increased;wherein the three holes reduce said impact force; andwherein the radius of each of said apex is raised a sufficient distance from its base such that said panels create a raised outside surface of said outer shell. 12. The helmet of claim 11, wherein the inside surface of the outer shell is contoured to match the contours of the flat surface panels of the outside surface, and the inner shell comprises a top surface having contours configured to mate with the contours of the inside surface of the outer shell. 13. The helmet of claim 11, wherein the flat surface panels of the outside surface of the outer shell conjoin to form a plurality of apexes, and a plurality of said apexes comprise a plurality of holes disposed in fluid communication with the air cushion layer such that each hole permits ingress and egress of air to and from the air cushion layer. 14. The helmet of claim 12, wherein the flat surface panels of the outside surface of the outer shell conjoin to form a plurality of apexes, and a plurality of said apexes comprise a plurality of holes disposed in fluid communication with the air cushion layer such that each hole permits ingress and egress of air to and from the air cushion layer. 15. The helmet of claim 11, wherein the outer shell comprises at least one three-sided pyramid. 16. The helmet of claim 12, wherein the outer shell comprises at least one three-sided pyramid. 17. The helmet of claim 13, wherein the outer shell comprises at least one three-sided pyramid. 18. The helmet of claim 12, wherein the outer shell comprises at least one four-sided pyramid. 19. The helmet of claim 13, wherein the outer shell comprises at least one four-sided pyramid. 20. The helmet of claim 14, wherein the outer shell comprises at least one four-sided pyramid.
