CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. ยง 119(e) of U.S. Non-Provisional Patent Application Serial No. 15/163,920 filed on May 25, 2016, entitled "IMPACT- ABSORBING COATING," which is incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

[0001] The present disclosure generally relates to coatings. In particular, the disclosure relates to impact-absorbing coatings that absorb impacts from surfaces.

BACKGROUND

[0002] During contact sports and other physical activities, helmets have long been worn to protect users from sustaining injuries to the head and brain. Over time, helmets have included covers and liners in one form or another to absorb impacts to help better protect users. However, covers and liners alone can be insufficient in providing adequate protection to properly protect a user's head and brain. Being injured while wearing conventional helmets, even those that may include the latest technology for covers and liners, can result in serious injuries including sustaining a concussion and/or chronic traumatic encephalopathy (CTE) brain damage. As athletes experience long and short-term brain injuries resulting from head impacts, there is a need for more effective impact-absorbing helmets. Short-term brain injuries, such as concussions, typically result from falls where a player's head strikes the ground, impact with objects, and helmet-to-helmet contact. While there are protocols in place to protect players from concussions, repeatedly experiencing concussions can result in CTE brain damage which can be detected by medical resonance imaging (MRIs) and autopsies of athletes who have sustained multiple concussions and CTE. Consequently, traditional helmets, covers, and liners have many shortcomings and do not fully protect users.

[0015] According an embodiment of the present disclosure, FIG. 3 illustrates layer-by-layer assembly 200 of impact-absorbing coating 100 applied to surface 140. It should be appreciated that impact-absorbing coating 100 may include, but is not limited to, impact-absorbing material 110, outer skin 120, and bonding layer(s) 130. Impact-absorbing material 110 may include, but is not limited to, rubber, urethane, polymers, plastics, foam, non-foam materials, liquid-filled materials, and/or other impact-absorbing materials. In an embodiment of the present disclosure, impact-absorbing material 110 may have a thickness of approximately 3/8 of an inch or 0.375 inches. It should be appreciated that impact-absorbing material 110 may have a thickness more or less than approximately 3/8" depending on material properties and desired results without departing from the present disclosure. It should be appreciated that material 110 may be a single piece of material in some embodiments of the present disclosure; however, there may be other embodiments of the present disclosure where material 110 is formed of more than one layer.

[0016] According an embodiment of the present disclosure, FIG. 3 illustrates how impact- absorbing material 110 may coat or cover an exterior of object 140. It should be appreciated that impact-absorbing material 110 may cover object 140 in its entirety or any portion of object 140. Outer skin 120 may be provided over impact-absorbing material 110. It should be appreciated that outer skin 120 may cover impact-absorbing material 110 in its entirety in embodiments of the present disclosure; however, there may be other embodiments where outer skin 120 may cover some portion of impact-absorbing material less than in its entirety without departing from the present disclosure. Outer skin 120 may provide a paintable and decoratable finish, for example, such that it may be painted or decorated to coordinate with a team's colors. It should be appreciated that the paintable and decoratable finish may be provided through the use of any type of paint including, but not limited to, a matte paint, a glossy paint, and/or an array of colors. It should further be appreciated that the paintable and decoratable finish may be fused to impact- absorbing material 110 without employing a bonding agent or glue. It should be appreciated that one or more bonding layers 130 may be utilized to bond impact-absorbing coating 100 to object 140 and/or to bond components of impact-absorbing coating 100 together. For example, bonding layer 130 may bond impact-absorbing material 110 to object 140. Another bonding layer 130 may bond impact-absorbing material 110 to outer skin 120. It should be appreciated that there may be embodiments where bonding layer(s) 130 may not be utilized to bond impact- absorbing coating 100 to object 140 and/or to bond components of impact-absorbing coating 100 together without departing from the present disclosure.

[0017] According an embodiment of the present disclosure, impact-absorbing coating 100 may be flexible or pliable and may respond to hard impacts. It should be appreciated that a response to hard impacts may include, but it not limited to, bending, denting, deforming, and flexing. Impact-absorbing coating 100 may provide cushioning about an exterior of object 140 to which impact-absorbing coating 100 may be applied and may decrease an impact force between object 140 and the surface. It should be appreciated that impact-absorbing coating 100 may decrease an impact force between object 140 and the surface by approximately 40%. It should further be appreciated that impact-absorbing coating 100 may decrease an impact force by more or less than 40% without departing from the present disclosure. It should also be appreciated that impact-absorbing coating 100 may decrease an impact force from 100 G's to less than 60 G's which is generally considered the threshold for experiencing a brain concussion. It should be appreciated that when two objects each having impact-absorbing coating 100 collide, the object-to-object contact may result in approximately 3/4" or 0.75 inches of impact- absorbing material separating the two objects. It should further be appreciated that object-to- object contact may provide more or less than approximately 3/4" of impact-absorbing material between the two objects without departing from the present disclosure.

[0018] Impact-absorbing coating 100 may decrease an impact absorption of a user wearing the helmet by absorbing energy from an impact between object 140 to which impact-absorbing coating 100 is applied and a surface. Energy may be absorbed prior to being transmitted to object 140 or an outer surface of object 140. Following an impact between object 140 to which impact-absorbing coating 100 is applied and the surface, impact energy may be transmitted to an inner surface of object 140. Further, energy may be transmitted to a user of object 140. For example, an impact between a helmet and a surface may transmit impact energy to an outer shell of the helmet. After the impact of the helmet against a surface, impact energy may be transmitted to an inner impact lining of the helmet. The impact of the helmet against a surface may be transmitted to a user's skull and/or brain. It should be appreciated that impacts near 60 G's are generally considered to cause a lower threshold concussion compared to impacts near 100 G's. Impact absorption of the user wearing the helmet will not damage the user's health and/or cause the user to sustain injuries to different parts of the user's body including, but not limited to, a user's head, arms, neck, spine, and legs. Impact-absorbing coating 100 may also reduce an impact and/or damage sustained by another user's body, even if the user may not wear impact-absorbing coating 100. For example, impact-absorbing coating 100 may protect an extension of a user and/or another person including a body, arms, hands, legs, shins, nose, face, and other body parts when the person comes in contact with the user.

[0019] According to an embodiment of the present disclosure, it should be appreciated that impact-absorbing coating 100 according to embodiments of the present disclosure may reduce brain, neck, and/or spinal injuries that may result from head impacts during activities including, but not limited to, football games, baseball games, other sports, motorbike riding, other motor sports, and military, commercial, industrial, and vehicle applications. It should further be appreciated that impact-absorbing coating 100 may reduce head and brain trauma that may reduce trauma sustained by a user's neck and/or spine. It should be appreciated that impact- absorbing coating 100 may be used in any environmental conditions including, but not limited to, rain, snow, and sunlight as well as indoors and outdoors. It should be appreciated that impact- absorbing coating 100 may not show signs of weathering or wear. It should be appreciated that impact-absorbing coating 100 may remain tightly bonded to outer skin 120 throughout the lifetime of object 140 to which impact-absorbing coating 100 is applied. For example, impact- absorbing coating 100 may remain tightly bonded to an outer shell of a football helmet throughout the lifetime of the helmet. It should further be appreciated that if impact-absorbing coating 100 loosens from object 140 to which it is applied, object 140 may be discarded. It should also be appreciated that impact-absorbing coating 100 may be secured to object 140 so that impact-absorbing coating 100 will not loosen during normal use of object 140 to which impact-absorbing coating 100 is applied. It should be appreciated that impact-absorbing coating 100 may be non-obtrusive and may be transparent or camouflaged against object 140 to which it is applied in some embodiments of the present disclosure.
