BACKGROUND

Field
The present disclosure relates generally to impact mitigation devices for headgear and their method for attachment. More specifically, the present invention relates to headgear pads physically connected to headgear to mitigate the effects of impact on a wearer, especially the effects on the wearer's brain.
Description of the Related Art
While various sports and physical activities are widely considered to have a variety of positive effects on their participants, unfortunately, science is increasingly recognizing the negative effects as well. That is especially true regarding those sports and physical activities that include a substantial chance of impact, especially impact to a participant's head. Some of the sports and physical activities known to cause large numbers of head injuries include bicycling, football, lacrosse, baseball, softball, basketball, water skiing, soccer, skateboarding, downhill skiing, snowboarding, hockey and horseback riding. While football often has a reputation for causing the greatest number of head injuries, it has been reported that bicycling leads to a greater number of head injuries treaded in U.S. hospital emergency rooms. However, the precise impact of concussive and sub-concussive impacts over time is still in the early stages of study.
Although many sports have adopted strict helmet standards for their participants, and superficial cuts and bruises are correspondingly reduced, impacts to the head are still known to cause large numbers of cases of traumatic brain injury (TBI), including concussions and Chronic Traumatic Encephalopathy (CTE). The problem is so widespread that according to a press release from the Centers for Disease Control and Prevention (CDC) in 2007, “experts estimate that 1.6 to 3.8 million sports and recreation-related TBIs occur each year in the U.S.” A subsequent study led by Dr. Alan Zhang of the University of California, in San Francisco, Calif., reviewed health insurance claims for almost 9 million Americans and found that concussion diagnoses more than doubled between 2007 and 2014. The most significant jump was seen among 10- to 14-year-olds, whose injury rate more than tripled, and they were followed closely by 15- to 19-year-olds, the study found.
Concussion injuries are associated with rapid acceleration due to impact. While the brain is protected from light trauma by being surrounded by cerebrospinal fluid, there are limits to this protection that are often exceeded in sports and physical activities that cause the head to accelerate rapidly. Rapid acceleration can cause linear, rotational, angular and perhaps even wave-like movement of the brain. Concussion is caused by impact forces, in which the head encounters something at high speed, and impulsive forces, such as if a participant's headgear-covered head hits something and their head snaps forward or backward. There may also be instances where the force imparted is great enough to cause the brain to impact the side of the skull. Depending on the circumstances, concussion causes short term, and sometimes long term, cognitive symptoms including confusion, disorientation, difficulty focusing attention, changes in sleeping patterns, difficulty reasoning and performing everyday activities. Receiving a second concussion or subsequent concussion before the first concussion is completely healed has also been associated with long term damage. Additionally, the long-term damage of repeated, sub-concussive blows to the head is only recently being revealed. A 2010 Purdue study of high school football players concluded, “[p]layers sustaining the most sub-concussive hits (were) most likely to show cognitive impairment.”
While concussions are now widely known to be damaging, CTE, as a result of sports trauma, is also coming under increasing scrutiny. CTE was first described by Dr. Bennet Omalu in his paper titled, “Chronic Traumatic Encephalopathy in a National Football League Player,” published in the journal Neurosurgery in 2005. Subsequently, Boston University established a CTE center to further study the problem. It has been reported that Boston University has identified signs of CTE in nearly 60 former professional football players when their brains were analyzed postmortem. CTE is thought to be caused by repeated blows to the head, which damage brain tissue and lead to a buildup of an abnormal protein called tau.
Concerns about traumatic brain injury are likely negatively affecting participation in otherwise beneficial sports and physical activities at all levels. For example, a survey conducted by the University of Pittsburgh Medical Center in October 2015 found that 1 in 3 parents “live in fear that their child will get a concussion” and that 1 in 4 “do not let their kids play some contact sports because of fear of concussion.” For those who choose to participate, the risks of traumatic brain injury are a serious and legitimate concern. Unfortunately, helmets, caps and other headgear are clearly not preventing concussions, significant sub-concussive impacts and other events contributing to brain trauma.
In view of the foregoing, it would be beneficial to mitigate the forces imparted to the brains of participants in sports and physical activities.

Note that the configuration of headgear pads 505 shown in FIG. 6 is being tested by being impacted against a test anvil 645 which is causing one of the headgear pads 650 to be compressed as shown in FIG. 6 due to an impact of the type encountered in football. During such impacts, some of the force that would have been transmitted to the wearer's brain, potentially causing TBI, including concussions and/or CTE, is instead absorbed by the deformation of the headgear pads 505. Note that the headgear pads 505, other than headgear pad 650, may or may not be compressed as shown in this test in FIG. 6.
Referring to FIG. 7A, a first chart of results of impact testing 700 corresponding to the embodiment of the plurality of headgear pads attached to the football helmet of FIG. 6, according to the present disclosure, is shown. The testing was performed by Chesapeake Testing, an independent testing laboratory located at 4603B Compass Point Road, Belcamp, Md. 21017. The first chart 700 shows a Severity Index (SI) 755 of 68. This corresponds to a 56% reduction in impact severity of the helmet 510 with headgear pads 505 having an SI of 68 as compared with the helmet 510 without helmet pads having an SI of 156. Severity Index is standard defined by the National Operating Committee on Standards for Athletic Equipment (NOCSAE). According to NOCSAE, “NOCSAE' s Severity Index (SI) is a threshold value for a general category of head injuries based on scientific research and published data. SI is a method for measuring a helmet's ability to reduce impact forces to the head, integrating acceleration over time. SI provides an accurate way to assess head injury risk that can be replicated across laboratories and under different impact scenarios. NOCSAE standards are performance-based and are design neutral so that manufacturers are not restricted in design or engineering, allowing innovation in design.” (http://nocsae.org/wp-content/uploads/2011/10/NOCSAE-Severity-Index-FAQs-1-2015.pdf)
Referring to FIG. 7B, a second chart of results of impact testing 700 corresponding to the embodiment of the plurality of headgear pads attached to the football helmet of FIG. 6, according to the present disclosure, is shown. The second chart 700 shows a Severity Index (SI) 755 of 68, corresponding to a 56% reduction in Severity Index (SI) as described above. This NOCSAE-compliant test result demonstrates a substantial reduction in impact forces due to the deformation of the headgear pads 505 absorbing those forces, thereby reducing the risk of TBI, including concussion and CTE.
Referring to FIG. 8, a close-up, perspective view of an embodiment of one headgear pad 800, according to the present disclosure, is shown. The headgear pad 805 is formed from polyurethane flexible form. The headgear pad 805 has an apex 820 containing an aperture 835.
