Patent Application
20170340045
The present disclosure generally relates to coatings. In particular, the disclosure relates to impact-absorbing coatings that absorb impacts from surfaces.
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.
Embodiments of the present disclosure may provide an impact-absorbing coating that may be applied to a helmet to reduce bodily injuries when the helmet impacts another object. The coating may include an impact-absorbing material that may provide a thickness of approximately ⅜″. The impact-absorbing material may coat an exterior of the helmet. An outer skin may be provided over the impact-absorbing material. The coating may cushion an exterior of the helmet to reduce head injuries when the helmet contacts with another object. The coating may reduce any combination of head, neck, and spinal injuries sustained by a wearer of the helmet to which the coating is applied. The coating may be flexible, and the outer skin may provide a paintable and decoratable finish. The coating may decrease an impact force of the helmet to which the coating is applied when the helmet contacts with another object. The coating may be integrally formed with the helmet, bonded onto the helmet, affixed to the helmet, or any combination thereof. The impact-absorbing material may be formed in layers. The outer skin may cover the entirety of the impact-absorbing material, and the impact-absorbing material may cover the entirety of the helmet. The impact-absorbing material may cover the entirety of the exterior of the helmet.
Embodiments of the present disclosure may provide a coating for reducing bodily injuries that may include an impact-absorbing material that may coat an exterior of a helmet. An outer skin may be provided over the impact-absorbing material and upon contact of the helmet with an object, the coating may decrease an impact force of the helmet and may reduce brain injuries to a wearer of the helmet. The coating may reduce any combination of head, neck, and spinal injuries sustained by a wearer of the helmet to which the coating is applied. The coating may be flexible and the outer skin may provide a paintable and decoratable finish. Contact may be the helmet colliding with the object at a force that may be greater than a predetermined force. The predetermined force may be an impact up to approximately 100 G's. The object may be selected from the group including a ground surface, a floor, an inanimate object, a wall, a person, an extension of a person and another helmet. The impact-absorbing material may have a thickness of approximately ⅜″. The coating may be integral with the helmet to which it is applied and may provide cushioning around an exterior of the helmet.
Embodiments of the present disclosure may provide an impact-absorbing coating that may be applied to an object. The impact-absorbing coating may include an impact-absorbing material may have a thickness of approximately ⅜″. The impact-absorbing layer of material may coat an exterior of the object. An outer skin may be provided over the impact-absorbing layer of material. When the object collides with a second object that may incorporate the impact-absorbing coating, the object-to-object contact may result in approximately ¾″ of impact-absorbing material between the object and the second object. The object and the second object may be selected from the group including an athletic helmet, a hat, a non-athletic headgear, a stationary object, a moving object, a wall, a piece of athletic equipment, a ground surface, a person, an extension of a person, and a floor. The coating may decrease an impact force of the object to which the coating is applied when the object contacts with a second object.
Other technical features may be readily apparent to one skilled in the art from the following figures, descriptions and claims.
For a more complete understanding of this disclosure, reference is now made to the following description, taken in conjunction with the accompanying drawings, in which:
The present disclosure generally provides an impact-absorbing coating that may be applied to helmets or other objects that may be worn on the head in order to reduce the likelihood of concussions or brain, neck, and/or spinal injuries in wearers of the helmets.
According to an embodiment of the present disclosure,
It should be appreciated that a hard impact may include, but is not limited to, a helmet colliding with a surface at a force that may be greater than a predetermined force. It should be appreciated that a predetermined force may include, but is not limited to, impacts of up to approximately 100 G's. It should further be appreciated that impacts greater or less than approximately 100 G's may provide a predetermined force that may be suitable for a specific application, such as, a helmet including impact-absorbing coating 100 in which the helmet may be worn while participating in motor sports, and other sporting, industrial, commercial, and military activities.
It should be appreciated that object 140 (
According an embodiment of the present disclosure,
According an embodiment of the present disclosure,
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 ¾″ 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 ¾″ of impact-absorbing material between the two objects without departing from the present disclosure.
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.
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.
