BACKGROUND OF THE INVENTION

1. Field of Invention

The disclosed subject matter is in the field of helmets and other protective headgear.

2. Background of the Invention

Helmets and other protective headgear (collectively “helmets”) exist to shield or otherwise insulate a wearer's head from forceful impacts during hazardous activities. Structurally, helmets are typically defined by a hard shell that is internally lined with soft, shock-absorbing materials. In a typical mode of use, a wearer positions his or her head inside of the shell so that the head is surrounded by the shock-absorbing material. The hard outer shell of the helmet is intended to deflect the blunt force of an impact while the shock-absorbing material is intended to absorb any remaining forces associated with the impact whereby the head is protected.

Certainly, modern helmets have been satisfactory for protecting the external and skeletal components of the heads of helmet wearers during helmet impacts. However, it has been recently suggested that the internal or non-structural components of the wearer's head are not adequately protected by helmets. The thought is that the abrupt acceleration or deceleration of a wearer's head during an impact causes the brain and other internal organs of the wearer's head to slosh to-and-fro within the brain cavity of the head and sustain trauma via impacting the skeletal or structural components of the wearer's head. Such brain trauma is known to result in concussions of the wearer. Concussions can be particularly problematic during activities, like American football, in which a wearer is continuously subjected to abrupt accelerating/decelerating helmet impacts because chronic traumatic encephalopathy (CTE) (a degenerative disease) may ultimately afflict the helmet wearer.

In view of the foregoing, a need exists for improvements to helmets. Specifically, a need exists for helmets that both (a) protect the wearer's head structure from the blunt force of an impact and (b) smoothly to decelerate the force of an impact so that the non-structural components of a head are protected during the impact. In view of this need, many modifications to helmets have been proposed but ultimately fail to meet the stated need. U.S. Pat. No. 5,724,681 (issued Mar. 10, 1998) by Sykes discloses a “Shock-absorbing helmet cover.” Sykes' disclosed improvement is simply an extra protective shell around the helmet which is aesthetically unappealing and does very little to decelerate helmet impacts. Unattractive helmets are problematic because participants in certain activities, like American Football, are image conscious and will not wear an ugly helmet. U.S. Pat. No. 4,307,471 (issued Dec. 29, 1981) by Lovell discloses a “protective helmet” with an outer shell that is slidably connected to the helmet so that the outer shell and the helmet move forward or backward relative to one another during impacts. The relative movements between the outer shell and helmet of Lovell can decelerate head-on impacts, but the outer shell does not adequately protect against side-impacts because the shell can only move forward and backwards relative to the helmet. Thus, a need still exists for improved helmets that are aesthetic and that can decelerate impacts from any direction.

SUMMARY OF THE INVENTION

In view of the foregoing, an object of this specification is to disclose a helmet that is aesthetically appealing and that is capable of decelerating impacts from any direction. In a preferred embodiment, the helmet features: a shell with a head cavity that is lined with shock absorbing material, wherein the shell is outfitted with a halo of deceleration plates. In one embodiment, the deceleration plates are triangular and positioned around the crown of the helmet so that one point of every plate meets generally at the top of the helmet. Suitably, all of the plates are sandwiched at the top of the helmet between a holding plate and the shell, wherein each plate may shift around the contours of the helmet and under the holding plate in response to an impact. In a preferred mode of operation, shifting of the plates is resisted by a gel, e.g., silicone gel. Operably, the plates shift in response to an impact and absorb a portion of the impact energy.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Disclosed is a helmet that is aesthetically appealing and that is to capable of decelerating impacts from any direction. In a preferred embodiment, the helmet features: a shell with a head cavity that is lined with shock absorbing material, wherein the shell is outfitted with a halo of deceleration plates designed to shift around the contours of the helmet and under the holding plate in response to an impact. The more specific details of the disclosed helmet are disclosed in connection with the attached figures.

FIG. 1 is an environmental view of a helmet 1000 with deceleration plates 1100. FIGS. 2 through 7 are respectively a front view, a back view, a left-side view, a right-side view, a bottom view, and a top view of the helmet 1000 with deceleration plates 1100. As shown, the preferred embodiment of the helmet 1000 features: a shell 1200 with a head cavity 1210 that is lined with shock-absorbing padding 1400; a facemask 1300; a holding plate 1500; a halo of deceleration plates 1100 designed to shift around the contours of the helmet and under the holding plate 1500 in response to an impact; and shock absorbing gel 1600 for resisting the shifting of the plates 1100 to under the holding plate 1500.

Still referring to FIGS. 1 through 7, the deceleration plates 1100 are some-what triangular and molded around the helmet so that one point 1110 of every plate 1100 meets generally at the top of the helmet 1100. See, e.g., FIG. 6. In the preferred embodiment, five or six some-what triangular carbon-fiber plates 1100 are employed wherein the point 1110 has an angle 2000 (FIG. 6) of approximately 60 to 72 degrees. More or less than five or six plates may be used, but five or six is preferable. In on embodiment, each plate 1100 features a foot 1120 by which the plate 1100 may be rigidly secured to the shell 1200 around the perimeter of the head cavity 1210 of the shell 1200. See FIGS. 4, 5 and 7. In the preferred embodiment, the plates 1100 bulge outwardly from the foot 1120 so that an airspace 1130 (not shown until FIG. 8) is provided between the shell 1200 and the plate 1100. The air space 1130 (not shown until FIG. 8) is discussed in greater detail below in connection with FIG. 8. Suitably, all of the plates 1100 are slidably held at the at the top of the helmet 1000 between a holding plate 1500 and the shell 1200, wherein, as discussed further below, each plate 1100 may shift around the contours of the helmet 1000 and under the holding plate 1500 in response to an impact. In a preferred mode of operation, shifting of the plates is resisted by a gel 1600, e.g., silicone gel, that is sandwiched between the holding plate 1500 and the shell 1200.

FIG. 8 is a cross section of the helmet 1000. FIG. 8 illustrates an air space 1130 between the deceleration plates 1100 and the shell 1200 or to protective surface of the helmet 1000. As discussed above, each plate 1100 may feature a foot 1120 by which the plate 1100 may be rigidly secured to the shell 1200 around the perimeter of the head cavity 1210 of the shell 1200. From the foot 1120, the plates 1100 bulge slightly outwardly so that the airspace 1130 is provided between the shell 1200 and the plate 1100. Suitably, all of the plates 1100 are slidably held at the at the top of the helmet 1000 between a holding plate 1500 and the shell 1200, wherein, as discussed further below, each plate 1100 may shift around the contours of the helmet 1000 and under the holding plate 1500 in response to an impact. Suitably movement of the plates under the holding plate 1500 is resisted by the gel 1600. In one embodiment, the tip 1110 may feature a track or cutout so that the movement of the deceleration plates 1100 may be guided.

FIG. 9 is an environmental view of the helmet 1000 with deceleration plates 1100 compressed towards one another. As discussed above, the deceleration plates 1100 may shift around the contours of the helmet 1000 and under the holding plate 1500 in response to an impact. Referring to FIGS. 1, 8 and 9, the plates 1100 deflect from the position shown in FIG. 1 toward and underneath the holding plate 1500 in response to an impact. The result is the position shown in FIG. 9, where every plate 1100 has been deflected under the holding plate 1500. Referring now to FIG. 8, during said deflection, the air space 1130 (FIG. 8) is reduced. Suitably, the movement of the deflecting plates 1100 decelerates the impact. It should be noted that, even though all of the deceleration plates 1100 are shown as deflected under the holding plate 1500 at the same time, it is contemplated that one or more of the deceleration plates 1100 may be deflected by itself or with multiple plates 1100 being deflected from a single impact. FIG. 10 is a diagram of a typical use for the helmet 1000 disclosed. As shown in the figure, when two helmets (A) are impacted (B) the deceleration plate 1100 are moved within the holding plate 1500.
