## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to helmets and, more specifically, to a convex shaped helmet for encompassing the back of the head having adjustable retaining straps extending across the front. The helmet is positioned engaging the back of the head with an adjustable strap extending across the forehead with an additional adjustable strap extending medially from the first strap engaging the helmet at its distal end. The straps prevent shifting of the helmet during use. The helmet is comprised of an external shell manufactured from an impact resistant material and has an interior layer of a compressible material to engage the wearer's head.
The purpose of the helmet is to protect the back of the wearer's head during use. Many head injuries in sports are caused by backward falls resulting in damage or injury to the posterior portion of the head such as the external occipital protuberance, occipital bone and parietal bone. The instant invention overcomes such injuries by providing a convex shaped helmet, comprised of a hard, polymeric material having elastomeric adjustable head bands for securing said helmet to a wearer's head. The interior concave portion of the helmet is covered with a soft cushion foam like padding for comfort and further protection.
The device of the present invention is ideal for action sports minded children or for active children is a playground. With the helmet of the present invention, head injury due to backward falls can be eliminated.
Some of the sports the present invention can be utilized for are wrestling, basketball, volleyball, tennis, soccer, skate boarding, and jump rope or just playing in a playground. Another use would be for physical education classes and physical therapy classes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail one embodiment of the invention. This discussion should not be construed, however, as limiting the invention to those particular embodiments since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention, the reader is directed to the appended claims.
Turning to FIG. 1, shown therein is an illustrative view of the type of injury that can occur under prior art conditions. Many head injuries in sports are caused by backward falls resulting in damage or injury in the impact area 16 of the posterior portion 12 of the head 14 of a user 18 such as the external occipital protuberance, occipital bone and parietal bone during a backward fall. The present invention over comes such injuries by providing a convex shaped helmet, comprised of a hard, polymeric material having elastomeric adjustable head bands for securing the helmet to a wearer's 18 head 14. The interior concave portion of the helmet is covered with a soft cushion foam like padding for comfort and further protection. The device of the present invention is ideal for action sports minded children or for active children 18 in a playground. With the helmet of the present invention, head injury due to backward falls can be eliminated. Some of the sports the present invention can be utilized for are wrestling, basketball, volleyball, tennis, soccer, skate boarding, and jump rope or just playing in a playground. Another use would be for physical education classes and physical therapy classes.
Turning to FIG. 2, shown therein is an illustrative view of the present invention 10 in use. Shown is the present invention 10 comprised of a convex shaped helmet 20 formed of a hard polymeric material having elastomeric adjustable headbands 22, 24 providing means for securing the helmet 20 to the head 14 of the user 18. The interior surface of the helmet 20 has a layer of foam-like padding. The helmet 20 is worn on the posterior portion 12 of the head 14 to protect the external occipital protuberance, occipital bone and parietal bone from a severe blow as during a backward fall.
Turning to FIG. 3, shown therein is a side view of the present invention 10 in use. Shown is the present invention 10 in use whereby a user 18 places the convex helmet 20 over the back 12 of the head 14. The convex housing has means for retaining the protective helmet 20 over the back 12 by means of an adjustable strap that extend across the forehead 22 and a strap 24 extending from the top of the helmet to the forehead. Each strap 22, 24 has means 28 whereby a user 18 can selectively adjust the tensioning of the straps to suit the user. The strap 24 is movable along strap 22 at the point of attachment of strap 24 to strap 22. The exterior shell of the helmet 20 is comprised of an impact resistant material such as a hard polymeric material. A logo 26 may be conspicuously placed on the present invention 10.
Turning to FIG. 4, shown therein is a frontal view of the present invention 10 in use. Shown is a front view of a user 18 wearing the protective helmet 20 of the present invention 10. As shown the helmet 20 is a low profile device designed to protect the back of the head 14 from injury due to a severe blow. The provided straps 22, 24 enable the user 18 to selectively position the helmet 20 and maintain the positioning by adjustment of the tensioning members 28. The device 10 has a relatively small footprint, therefore the device will not inhibit the user's 18 peripheral vision or obstruct their hearing or encompass the top of the head 14 which would retain heat. The device 10 is particularly unobtrusive while affording protection from severe head injury that can occur from a fall.
Turning to FIG. 5, shown therein is a perspective view of the present invention 10. Shown is a perspective view of the present invention 10 comprised of a convex shaped helmet 20 formed of a hard polymeric material having a cushioned interior liner 30 comprised of a foam-like material designed for the comfort of the user as well as additional protection. The helmet 20 has elastomeric adjustable headbands 22, 24 providing means for securing the helmet to the head. The helmet 20 is worn on the posterior portion of the head to protect the external occipital protuberance, occipital bone and parietal bone from a severe blow as during a backward fall. Adjustment means 28 are also shown along with a logo 26.
Turning to FIG. 6, shown therein is a rear view of the present invention 10. Shown is a rear view of the present invention 10 showing a helmet 20 for encompassing the back of the head to protect the external occipital protuberance, occipital bone and parietal bone from a severe blow as during a backward fall. The helmet 20 is comprised of a suitable impact absorbent material to prevent the helmet from cracking. Additionally, the helmet 20 has elastomeric adjustable headbands 22 providing means for securing the helmet to the head and to prevent movement during use. The user adjusts the elastomeric straps 22 to a suitable comfort level.
Tuning to FIG. 7, shown therein is a front view of the present invention 10. Shown is a front view of the present invention 10 comprised of an exterior impact absorbent material or helmet 20 and an interior foam-like material 30 that engages the external occipital protuberance, occipital bone and parietal bone and conforms substantially to the shape of the user's head. The adjustable elastomeric straps 22, 24 provide means for securing the helmet 20 to the head and to prevent movement during use. Centrally located on the straps 22, 24 convergence is an area where a logo 26 or advertisement can be placed. Adjustment means 28 are also shown along with a logo 26.
Turning to FIG. 8, shown therein is a sectional view of the present invention. Shown is a sectional view of the present invention showing the convex helmet 20 or structure of the exterior surface forming a shell that will encompass the back of the head. On the interior surface of the helmet 20 is a layer of foam-like material 30 that is bonded to the interior surface of the helmet 20 by any means well known within the art such as adhesively. The foam liner 30 affords the wearer comfort and conforms to the shape of the user's head which allows for the helmet 20 to be made in various general sizes.
