Various exemplary embodiments disclosed herein relate generally to a helmet removal system and, more particularly, to a helmet removal system including a helmet liner configured to eject the user's head from a helmet by distributing forces applied to the helmet liner to the helmet and user's head.
One of the most important aspect of sports is ensuring safety to the participants. This is especially true for contact sports, such as skiing, car racing, football, and hockey, for example, which require participants to wear helmets to prevent catastrophic head injuries. Helmets are designed to protect the user's head from impacting objects. Most helmets are designed to provide a snug fit between the user's head and the helmet to reduce movement of the user's head inside of the helmet during use.
Occasionally, participants wearing helmets and partaking in sports are injured and require medical attention. In such cases, individuals, such as emergency personnel, may need to remove the participant's helmet and safety gear in order to administer effective medical care. As such, the emergency personnel typically removes the helmet from the user (in a laying position) by applying a pulling force on the helmet, longitudinal to the person's body and neck, to slide the helmet off of the user.
Because of the tight fit between the helmet and the user's head, upon attempted movement of the helmet from the head, frictional forces typically exist between the user's head and the interior of the helmet. As such, frictional counterforces may obstruct or prevent the helmet from being slid off of the user's head easily. As a result, the safety personnel may need to exert enhanced force to the helmet. This enhanced force may be transferred to the head, as well as the neck, causing further injury to the injured individual.
Human anatomy provides that seven (7) cervical vertebrae form the bones of the neck that support the skull and organs of the head. The first cervical vertebra (atlas) supports and balances the head. The second vertebra (axis) allows the head to rotate laterally to the left and the right. Hollow spaces within the cervical vertebrae protect and conduct the spinal cord and vertebral arteries through the neck. Muscle attachment sites on the cervical vertebrae provide movement and posture to the head and neck.
By pulling on the head or helmet to remove the helmet from the injured individual, the emergency personnel may cause further permanent damage to the bones and neck supporting the skull and organs of the head, such as paralysis or death. Accordingly, the act of pulling a helmet off of a user longitudinally, providing a separating force, is highly discouraged. Unfortunately, during an emergency, helmet removal from the injured individual may be totally essential to provide the user with effective medical treatment.
A brief summary of various exemplary embodiments is presented below. Some simplifications and omissions may be made in the following summary, which is intended to highlight and introduce some aspects of the various exemplary embodiments, but not to limit the scope of the invention. Detailed descriptions of a preferred exemplary embodiment adequate to allow those of ordinary skill in the art to make and use the inventive concepts will follow in later sections.
The helmet removal system facilitates removal of a helmet from a user's head without requiring pulling forces to be applied to the head and helmet. The helmet removal system includes a removably detachable helmet liner configured to be positioned in the helmet. The helmet liner includes a central portion configured to receive a user's head therein, and a frontal portion integrally formed with the central portion and configured to engage the user's frontal head portion. The helmet liner further includes dual side tab portions also integrally formed with the central portion. The dual side tab portions are flexibly configured to be moved between a folded position for storage inside of the helmet to an unfolded position outside of the helmet.
The helmet liner of the helmet removal system further includes a top portion extending between opposing top edges of the central portion. The top portion is configured to engage the top portion of the users head and apply a longitudinal force in a second direction when the helmet liner tab portions are pulled laterally during helmet removal. The helmet liner further includes a rear portion integrally connected to the central portion to provide a balancing engagement with the back of a user's head. The rear portion further prevents displacement of the helmet liner from the head.
In operation, an individual applies lateral pulling forces to the dual tab portions of the helmet liner, in a direction generally perpendicular to user's helmet. As such, the outer surfaces of the dual tab portions engage the lower edge of the helmet. The tab portions apply a longitudinal force to the lower edge of the helmet in a first direction forcing the helmet away from the user's head. Simultaneously, the top portion of the helmet liner applies a longitudinal force on the user's head in an opposing second direction.
In various embodiments of the helmet removal system the rear portion of the helmet liner provides a balancing force to the back of the user's head preventing displacement of the head from the helmet liner, when lateral forces are applied to the dual side tab portions.
In further various embodiments of the helmet removal system, the frontal portion of the helmet liner provides a balancing force to the front of the user's head preventing migration or displacement of the helmet liner from the user's head, when lateral forces are applied to the dual side tab portions.
In further various embodiments of the helmet removal system, the dual tab portions each have rigid end portions configured for insertion between the inner shell of the helmet and the outer shell of the helmet.
In further various embodiments of the helmet removal system, the central portion of the helmet liner defines a generally circular configuration adapted to receive a user's head therein and provide a stabilizing force preventing displacement of the helmet liner from the head during helmet ejection.
In further various embodiments of the helmet removal system, the helmet liner includes a first opening is provided between the top portion and frontal portion in the helmet liner, and a second opening is provided between the top portion and the back portion.
The method of removing a helmet from a user's head, includes the steps of: providing a removably detachable helmet liner in a helmet having dual tab portions extending from the side of the helmet liner. Thereafter the method includes applying lateral pulling forces to the dual tab portions such that longitudinal forces are applied to the lower edge of the helmet in a first direction and longitudinal forces are applied to a top portion of the user's head in an opposing second direction. As such, movement of the helmet and head in opposing respective directions ejects the helmet from the user's head.
In order to better understand various exemplary embodiments, reference is made to the accompanying drawings, wherein:
To facilitate understanding, identical reference numerals have been used to designate elements having substantially the same or similar structure or substantially the same or similar function.
The description and drawings merely illustrate the principles of the invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the invention and are included within its scope. Furthermore, all examples recited herein are principally intended expressly to be only for pedagogical purposes to aid the reader in understanding the principles of the invention and the concepts contributed by the inventor(s) to furthering the art, and are to be construed as being without limitation to such specifically recited examples and conditions. Additionally, the term, “or,” as used herein, refers to a non-exclusive or (i.e., and/or), unless otherwise indicated (e.g., “or else” or “or in the alternative”). Also, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments can be combined with one or more other embodiments to form new embodiments.
In providing effective medical treatment to an injured individual wearing a helmet, it is desirable to reduce any and all pulling forces applied to the individual's head and/or neck during removal of the helmet. The ability to reduce the forces applied to the head and neck can be the difference between paralysis, and even life or death. Accordingly, it is desirable to provide a helmet removal system capable of facilitating the removal of the helmet from a person's head, without applying pulling forces to the individuals head and neck.
The helmet removal system facilitates safety personnel in sliding the helmet off an individual, without pulling on the helmet and head. The helmet removal system uses a helmet liner that distributes forces exerted on the helmet liner laterally into longitudinal forces applied to the outer edges of the helmet, in a first direction, and to the top of the head, in an opposing second direction. Further the helmet liner distributes the lateral forces to the frontal region, top region and back region of the head preventing displacement or migration of the helmet liner from the head during helmet removal.
