Description:
CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of U.S. Provisional Application Ser. No. 62/332,913, filed May 6, 2016, the disclosure content of which is hereby incorporated by reference in its entirety. 
     
    
     FIELD OF INVENTION 
       [0002]    The present application is generally related to soft athletic helmets and closure mechanisms for the same, specifically, closure mechanisms at the rear portion of the helmet for securing the hair of the user. 
       BACKGROUND OF THE INVENTION 
       [0003]    Athletic competition continues to evolve where athletes are faster and stronger, and thus athletes face greater risk of injury due to their own strength, the strength of their competition, and the ability to throw a ball with greater force than ever before. This evolution is present for both men and women, yet the protection provided to female athletes is not commensurate in protection to those afforded to male counterparts. 
         [0004]    Women&#39;s athletics continue to evolve at a rapid pace from mostly non-contact sports to sports that show few, if any, differences from the male version of the game. This is especially evident in several field sports, including lacrosse and field hockey, where today, women&#39;s lacrosse and women&#39;s field hockey continue to evolve to include additional physical contact, whether explicitly allowed by the rules, or simply by virtue of evolution of the game and the speed and skill of those playing. 
         [0005]    However, both women&#39;s lacrosse and women&#39;s field hockey have typically eschewed the use of face protection or helmets because of the fact that the sports, by rule, do not allow physical contact on the field. However, the current state of the game reveals that today, athletes, coaches, and parents of young athletes understand that physical contact is inevitable and that young athletes, in particular, are highly susceptible to head injuries while playing in organized sports. Specifically, there is an increased awareness of the danger and frequency of concussion in organized sport. Furthermore, modern research and studies have identified that repeated concussions may have a significant and long term effect on athletes, including the development of chronic traumatic encephalopathy, which is a degenerative disease highly correlated to those individuals who have suffered from repeated head injuries. 
         [0006]    While women&#39;s lacrosse and field hockey have been slow to adapt the use of helmets on the field, there appears to be momentum towards adopting rules and regulations regarding the use of helmets in competition. Therefore, the use of helmets seems like a natural, if not inevitable, component of the uniform for participation. 
         [0007]    The initial proposals for women&#39;s helmets specify the use of a soft shelled and flexible helmet and eschews the use of the hard-shelled helmets used in sports such as American Football, or in men&#39;s lacrosse. The argument is that women&#39;s lacrosse remains a non-contact sport and checking or hitting of another player remains prohibited by rule. Therefore, without the need to use the heavy, bulky and rigid helmets from men&#39;s sports, the proposed helmets will be less bulky and prevent loss of the dexterity and speed. However, the governing bodies remain interested in providing a helmet that will provide protection in the form of a soft/flexible helmet and which provides for substantial protection to the eyes, face, and head of athletes. 
         [0008]    Accordingly, because of incidental physical contact and also direct contact with a stick or ball, there is a need for sport specific head protection, eye protection, and protection of the face of female athletes. Therefore, there is a real and present need to improve safety for athletes in these sports, specifically by providing for sport appropriate head gear.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0029]    The embodiments of the invention described herein provide for a new soft helmet comprising an outer shell  1  and an inner core  20 , wherein the inner core and outer shell comprise a rear flap  7  and latching mechanism at the back of the helmet. The need for the rear latching mechanism is twofold. First, there is no current helmet that provides for a mechanism to secure a pony-tail or otherwise hair in the rear of the helmet. This is often highly important for women, so as to secure hair so it is not in the way while participating. And second, a more pressing reason for the need to have a flap and latching mechanism is that the helmet must also pass certain safety tests, which include a pressure test positioned at the rear portion of the helmet. 
         [0030]    Applicants designed several helmets and tested these against standard testing practices to confirm that the soft helmets would pass the necessary impact tests. However, a unibody construction that did not include the rear latching mechanism, failed the rear impact test (testing e.g. a ball hitting the helmet at high speed). By incorporating a two piece construction, an inner core, an outer shell, and incorporating a latching mechanism for a rear positioned flap, the helmet advantageously disperses impacts to the top, side, front, and rear of the helmet, to pass standards set in the industry for helmet protection. 
         [0031]      FIG. 1  provides a depiction of a soft helmet having a protective outer shell (protective outer layer)  1 , and an inner impact attenuating layer (or inner core)  20 , wherein the inner core  20  in  FIG. 1  depicts the left rear support  4  and the right rear support  6 . The inner core  20  is an impact dispersing layer made of a stiff material that is not completely rigid, but is not as flexible or pliable as the material of the outer shell  1 . The goal of the stiff material is to create support to allow for forces to be spread through the entirety of the helmet, thus dissipating the forces at the spot of impact. The material is properly made of a plastic or polymer material that provides for these features and also to support the outer shell  1 . In certain embodiments, the inner core is a non-compressible material. 
         [0032]    In comparison to the inner core  20 , the outer shell  1  is a soft, compressible material having impact attenuating properties. The outer shell is appropriately made of an open cell or closed cell material, that can be compressed and return to substantially its original shape after impact. Certain low density open cell foams are appropriate, however, some closed cell foams, and those of a medium or high density may be appropriate in certain instances. In other embodiments, the outer shell  1  is an outer protective layer made of an elastomeric material. Indeed, the outer shell material is comprised of any of several compressible or flexible foam or foam like materials that provide impact attenuation and that return to their original shape after impact. The compression aids in the reduction of forces, as is known to a person of ordinary skill in the art. Force is directly reduced by the increase in time to impact, such that the more something compresses, the greater reduction in force is possible. 
         [0033]    The outer shell and inner core are a generally domed shape with a crown, a rear, two sides, and a front. At the front, in certain embodiments, is a protruded lip or a visor like feature. However, the dome shape provides for a fit over the head of a user to expand the shells to the forehead of a user, adjacent to the ears, and at the rear, base, to just above the occipital bone. 
         [0034]    The outer shell  1  fits tightly over the inner core  20  and when paired together, the helmet retains some flexibility. The flexibility is due, in part, to the inner shell opening  5 , which allows for the left and right supports  4  and  6  so move and also to the material itself, having some ability to flex or give when the helmet itself is compressed. Therefore, the helmet can be compressed to some extent and is not rigid, in direct contrast to an American football style helmet that is both rigid and does not compress. In certain embodiments, the outer shell  1  and inner core  20  are glued together. In other embodiments, the two components may be adhered together by a glue or adhesive, hook and loop material, snap type connectors, and the like. Alternatively, the two components may be secured only by a tight fit and friction. 
         [0035]    The outer shell  1  comprises a rear flap  7  having a hingeable portion  30  connected to the outer shell  1  and a snap  18  at the end of the rear flap that secures to a corresponding snap  3  positioned on the left rear support  4  of the inner core  20 . The manner in which this is disposed, allows for the rear flap core  11  material disposed of in the interior surface of the rear flap  7  to extend beyond the inner shell opening  5  and over each of the left and right supports. This effectively provides for a portion of the inner core  20  material to cover the inner shell opening  5 . Because of the inner core opening  5  and the rear opening  2  above the rear flap  7 , an individual can pull hair through the openings and comfortably seat the helmet on her head. 
         [0036]    The design of the inner core  20  provides for the inner core opening  5  to be positioned at the rear of the head, wherein the inner core opening  5  is poisoned to allow a sufficient opening at the base of the rear of the head so that a ponytail  40  can pass through the inner core opening  5 . This opening extends from the base to about ½ way up the rear of the helmet towards the crown. Furthermore, the inner core opening  5  is designed to allow the rear left support  4  and the rear right support  6  to independently move. This, in turn, provides that the helmet can expand or be compressed slightly to improve the fit around the head of the individual user. Furthermore, forces applied to one side of the helmet, or to the rear of the helmet are dissipated through the moveable supports, the foam on the outer shell, the internal harness, and any additional internal shock absorbing materials. In particular, forces applied to the rear flap  7 , i.e. a ball, stick, or person hitting that position, will allow the forces to dissipate through the outer shell and then through through the independently movable supports on the left and right, thus limiting the force applied at this point to the head of the person wearing the helmet. 
         [0037]      FIG. 2  provides a further detail of the rear flap  7 , depicting that at the hingeable part  30 , the rear flap  7  is not connected to the right rear support  6 . The majority of the inner core  20  is in direct contact with the outer shell  1 , such that the two components are selectively attached to one another, except for the rear flap  7 . Indeed, this allows the rear flap  7  and the inner core  20  to independently move and allows for forces to move through the outer shell  1  and through each of the left and right sides of the inner core  20 . Therefore the rear flap  7  can be independently fastened or unfastened while the helmet is worn by a user. This allows a user to adjust their hair in and through the rear opening  2  as necessary for fit. 
         [0038]    Further depicted on the inner face of the rear flap  7  is a rear flap core  11 . The rear flap core  11  is composed of the same or a similar material as the inner core  20  and is positioned to provide a rigid support to the rear flap  7 . The snap  3 , is visible on the left rear support  4 , and will be utilized to selectively secure the rear flap  7 , which has a corresponding snap feature  18  on the inner portion of the rear flap  7 . By attaching the flap with attachment means, the rear flap core will cover the opening  5 , and thus protects the rear of the head adjacent to the occipital bone. 
         [0039]      FIG. 3  depicts the rear flap  7  having attachment means, here as depicted secured to the snap  3 . By snapping the rear flap  7  to the rear left support  4  of the inner core  20 , the outer shell  1  is secured around the player&#39;s head. The snap  3 , in certain embodiments is attached to the inner core  20  on a slideable mechanism, such that the precise position of the snap  3  can be modified for appropriate fit. Conversely, the corresponding snap  18  can be moveable on the rear flap  7 . In other embodiments, the snap can be positioned in one or more pre-drilled holes, so as to provide for a moveable fit. Accordingly, attachment means known to those of ordinary skill in the art can be utilized to secure the rear flap  7  to the left support  4  through snaps, peg and hole, buckle, hook and loop, string tie, and the like. 
         [0040]      FIG. 4  depicts on the left, the outer foam shell  1 , with the rear flap  7 . On the right, is depicted the inner core  20 , having the rear opening  5  between the left and right rear supports  4  and  6 , with a snap  3  on the left rear support. The position of the snap can be exchanged to the left or the right support, so long as the outer shell and rear latch  7  correspond to pair with its position. 
         [0041]    Also depicted in  FIG. 4  are closure straps  21  and an occipital dial  22  for tightening and loosening the closure straps  21 . The closure straps  21  are attached to the inner core  20  at opposite sides adjacent to the ear. The occipital dial  22  is positioned at the rear of the helmet and covered by a closure foam material  17  on the inside of the dial (see  FIG. 7 ). In further embodiments, the occipital dial  22  may be advantageously positioned to the side of the helmet, so as position the dial within the outer shell or away from the neck. The closure foam material  17  is preferably an open cell, low density style foam to attenuate any hit to the occipital dial  17 , but also for comfort in positioning and securing the helmet. This material may be the same as the foam for the forehead pad  9  and crown foam  10 , as one example. The specific thickness can be modified by the user for comfort, increased compression, and sizing. 
         [0042]    The occipital dial  17  allows the user to adjust the size of the helmet around the rear of the helmet. The occipital dial  17  comprises a rotatable disc that is connected to the closure straps on each side of the helmet, wherein rotating the disk will tighten or relax the fit. The rotatable disc can also utilize wire or string to tighten or relax the fit. In other embodiments, the mechanism to adjust the size of the helmed can be adjusted by other closure means, including, but not limited to snaps, hook and loop material, screw, rotation disk, or with adjustable straps and buckles as are known to one of ordinary skill in the art. 
         [0043]      FIG. 5  further depicts the occipital dial  22  at the base of the helmet. Rotation of the occipital dial tightens the straps to create the proper fit of the harness to the head. The ponytail is shown clearly extending through the rear opening  2  hole with the flap  7  secured below the ponytail and securing the helmet to the users head.  FIG. 6  provides a further image of hair extending out of the hole in the helmet and the flap  7  secured in position. 
         [0044]      FIG. 7  depicts a view of the inside of a helmet. The outer shell  1  is surrounding an inner core  20 . At the far right of the image, the outer shell  1  comprises a hat or visor portion  8 , which is a slightly protruding piece of the outer shell  1  foam. Directly inside of the hat portion  8 , and attached to the inner shell  20  at, what would be the forehead section, is a forehead pad  9 . This padding is preferably a compressible foam made of an ordinary low density open cell type foam, known to one of ordinary skill in the art. Positioned at the interior crown of the helmet is a crown foam  10 . Positioned near the ears, and also at the rear left and right are four compression pads  13 ,  14 ,  15 , and  16 . These compression pads provide for an improved fit for the helmet as well as improving the abilities of the helmet to disperse forces. The precise thickness of the foam and the specific location can be determined by one of ordinary skill in the art. Additionally, the helmet may comprise more than the six listed pads, including extra pads in the crown, at the temple, or positioned along the internal sides of the helmet. Suitable compression pads include open and closed cell foams or polymer materials as known to a person of ordinary skill in the art. 
         [0045]    Specific embodiments utilize compressible pads that comprise at least one type of compressible material surrounded by a membrane. The membrane has at least one hole to allow for air to enter and be compressed out of the membrane. For example, a particular brand of compression pad is a CRASH CLOUD™ pad, which comprises at least two types of foam material covered by a plastic membrane. 
         [0046]      FIG. 7  also depicts a chin strap  12 A and  12 B, wherein a strap is connected to each side of the helmet at or adjacent to the ear, and then connects under the chin of a user with an ordinary securing mechanism. Appropriate modifications to loosen or tighten the straps provides for a secure fit under the chin of the user. 
         [0047]      FIG. 7  further defines a pair of rear closure straps  21 . The rear closure straps  21  are connected to the inner core  20 , for example adjacent to the ear  23 . The rear closure straps  21  serve to secure the helmet to the head of the user, by incorporating a strap that sits at the rear of the head adjacent to the occipital bone. By placing the helmet on a user&#39;s head, the user can adjust the fit of the helmet by loosening or tightening these closure straps  21 . In a preferred embodiment, an occipital dial  22  is utilized and positioned at the rear of the helmet, and the occipital dial  22  can be rotated to tighten or loosen the closure straps  21 . In combination with the closure straps  21  around the rear of the helmet, by adjusting the occipital dial  22  and providing the appropriate level of closure foam material  17 , the helmet is properly secured to a user&#39;s head. The closure foam material  17  further assists in protecting the rear of the head from contact. 
         [0048]    Additional closure mechanisms may include a ring fit, variations of exchangeable pads having different thicknesses, for a pad fit, cam locks or various straps, snaps, hook and loop material, and the like. Many of these closure and securing mechanisms are in use or have been used in the bicycle helmet industry. The closure mechanism, whichever is utilized, assists in securing the closure straps  21  to create a snug fit around the rear of the head of the user. 
         [0049]      FIG. 8  depicts a bottom side profile of the helmet, again depicting the features from  FIG. 7 . 
         [0050]      FIG. 9  depicts a rear profile of the helmet. In particular, the rear flap  7  is pulled away from the helmet and a rear flap core  11  is depicted attached to the rear flap. Also depicted on the inner portion of the rear flap  7  is the corresponding snap feature  18  to pair with the snap  3  on the inner core  20 . The occipital dial  22  and the closure foam material  17  are also clearly depicted. 
         [0051]    The ability of the flap  7  to be affixed to the inner core  20  provides a secure connection, provides for an adjustable opening for the player based on head size, provides an opening for the hair of the user, and provides an important feature for disseminating forces applied to the rear portion of the helmet. Indeed, contact with the rear portion of the helmet will first hit the soft outer shell  1 , which will compress, due to the structure of the foam. The rear flap core  11  will then protect the shell opening  5  and forces will disseminate to the inner core  20  and to the left and right rear supports  4  and  6 . This will then allow the inner shell  20  to slightly compress, as the left rear support  4  and the right rear support  6  can flex to slightly narrow this shell opening  5 . Furthermore, these features can move independently thus allowing forces to be dispersed throughout the helmet and not concentrated on a single point. This aids in disseminating the forces applied to the rear of the helmet and assists in preventing injury should a direct force be applied to that portion of the helmet. Ultimately, the forces are applied to the compression pads  15 ,  16 ,  13 ,  14 , as well as  9 ,  10 , and  17 . The force compresses these pads, and the compression reduces the forces ultimately applied to the head. Together, the components of the helmet work together to reduce the forces as applied to a point on the helmet. 
         [0052]    In addition to the safety profile of the rear flap  7 , a further benefit of the rear flap  7  is the ease of which the player can undo the rear flap  7  and pull the player&#39;s hair through the shell opening  5  and the rear opening  2 . This provides for the easiest way to allow a user to comfortably orient their hair and also to securely and comfortably position the helmet to the user&#39;s head. In other helmets, there is no ability to open a latch, and so hair must be pulled through an opening. This can often lead to uncomfortable pulling of the hair, or worse, lead to unsafe positioning of the helmet. The use of a sport specific helmet, having an opening designed for safety and fit, and with the particular female user, or male user with long hair in mind, improves the ability of the helmet to securely fit and to maintain the proper fit throughout use. Proper fit and orientation of hair thus leads to a more secure and safe helmet. 
         [0053]    Furthermore, there are no other soft helmets that utilize a rigid inner core that comprises a rear opening  5 , followed by a compressible exterior foam shell that is positioned over and around the inner core, and that comprises a flap system that latches to one side of the inner core. Such system provides for an improved fit, greater comfort for the user, and provides for a safe and effective manner to secure the helmet for the user. 
         [0054]    Accordingly, in preferred embodiments, the helmet comprises a compressible outer impact attenuating material, an inner impact dispersing core that is stiff; wherein an opening is provided in the rear portion of both the inner impact dispersing core and in the corresponding same space in the outer impact attenuating material. Furthermore, provided is a first means to secure the helmet under the chin of a user and a second means to secure the helmet around the occipital bone. Disposed of on the interior surface of the inner impact dispersing core are compressible pads for attenuating forces.
