The present application is a Continuation-In-Part application of U.S. application Ser. No. 18/311,929, filed May 4, 2023, which claims priority to, and the benefit of, U.S. Provisional Application No. 63/424,501, which was filed on Nov. 11, 2022, both of which are incorporated herein by reference in their entirety.

The present invention relates generally to the field of head protection liner devices. More specifically, the present invention relates to a gel-type liner that can be placed inside of a helmet to help protect the scalp and brain from surface impact and injury. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.

By way of background, this invention relates to improvements in head protection liner devices. Generally, collisions while playing sports is one way a person may experience repeated head impacts, head injuries, and concussions. Further, without the proper headgear protection, long-term effects on the brain of people who experience multiple or repeated head impacts can have significant consequences.

Additionally, protective helmets for use in a variety of different sporting events, as well as a variety of recreational activities, are well known. However, helmets used by those engaged in certain sports, such as lacrosse, typically comprise a hard outer shell that surrounds a liner of energy-absorbing material. The hard outer shell of most protective helmets is typically comprised of a relatively rigid plastic material. When manufactured, helmets are typically assembled by inserting a pre-sized liner within a pre-sized outer shell. Although a standard helmet can approximately accommodate most users, natural variation in head sizes and head dimensions can cause the same helmet to fit differently on different users. In order to enhance the performance of a protective helmet, the helmet should conform securely to the user's head in all directions. When a helmet is not properly secured and can slip with respect to the user's head, an increased risk of injury can exist.

Accordingly, a need remains for a protective sport helmet liner that can be adjusted to conform to the head size and head dimensions of the user in all directions. Further, a protective head liner is necessary to protect against repeated head impacts, head injuries, and concussions that occur during sports.

Therefore, there exists a long-felt need in the art for a head protection liner device that provides users with a gel-type liner that can be placed inside of a helmet to help protect the scalp and brain from surface impact and injury. There is also a long-felt need in the art for a head protection liner device that features a silicone gel substance that can be molded to the shape of the head for maximum comfort and protection. Further, there is a long-felt need in the art for a head protection liner device that prevents cognitive, sensory, and mood-related symptoms that are often associated with head injuries. Moreover, there is a long-felt need in the art for a device that ensures durability with any type of helmet or headgear. Further, there is a long-felt need in the art for a head protection liner device that is shaped to the helmet and head of a user and absorbs the impact from any hard surface. Finally, there is a long-felt need in the art for a head protection liner device that utilizes a silicone gel substance that is one-half inch thick.

The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a head protection liner device. The device is a specialized headliner that can be placed inside any type of sports helmet in order to help absorb contact to the head. The head protection liner device comprises a body component comprised of a silicone gel substance. Typically, the silicone gel within the body component would be approximately one-half inch thick but can be any suitable size. The body component of the device is then placed within an inside of any sports helmet to help absorb contact to the user's head. Once placed on a user's head, the body component would conform to a user's head and will absorb impact from any hard surface. The body component can be secured within the inside of any type of helmet or headgear via any suitable securing means as is known in the art. Thus, the device is designed to protect the scalp and brain from any surface impact.

In this manner, the head protection liner device of the present invention accomplishes all of the foregoing objectives and provides users with a device that provides maximum comfort and protection for a user. The device is a gel-type liner that is placed inside a sports helmet. The device can be manufactured of a silicone gel substance that conforms to the shape of a user's head.

The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some general concepts in a simplified form as a prelude to the more detailed description that is presented later.

The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a head protection liner device. The device is a specialized headliner that can be placed inside any type of sports helmet in order to help absorb contact or impact to the head. The head protection liner device comprises a body component comprised of a silicone gel substance for energy absorption. Thus, the device is designed to protect the scalp and brain from any surface impact or injury.

In one embodiment, the body component is configured to be worn on its own, as a fashionable beanie and comes in a variety of colors and patterns. Specifically, the body component comprises an outer wall and an inner wall, in a curved configuration with a perimeter sidewall that extends down around a user's head. In this embodiment, the body component is crafted from a soft, pliable material and configured as a skull cap which provides a snug and secure fit that conforms to the contours of a user's head and provides enhanced comfort. In this way, the silicone gel substance of the body component helps regulate a user's head temperature, keeping a user cool and comfortable in hot weather or warm and cozy in the cold.

Further, the silicone gel substance of the body component can also be therapeutic, worn for enhanced relaxation, and can contribute to a more restful sleep experience.

Generally, the invention is directed to an energy absorption and displacement head protection liner device for a sports helmet. The head protection liner device provides impact absorption and energy displacement, and in a most efficient amount of space. When used as a helmet liner, the liquid injected gel liner provides a perfectly molded fit, while lowering the center of gravity to balance the helmet and improve performance and overall feel of the helmet. In addition to comfort, the impact reaction design of this invention creates a better, safer, softer, helmet than conventional helmets and liners.

In one embodiment, the head protection liner device is used with any type of sports helmet or headgear known in the art. Typically, the helmets in use with the liner device would comprise a hard outer shell with a peripheral edge and an inner wall. The protective hard outer shell may be made of known types of relatively rigid plastic material and is typically provided as a unitary piece of material.

In one embodiment, the head protection liner device comprises a body component with an outer wall that contacts the helmet interior and an inner wall that contacts the user's head. The body component can comprise any suitable shape and dimensions such that it substantially surrounds the upper portion of the skull of a user, including the parietal region of the head and is disposed at least partially about the back of the skull, such as at least partially disposed about the occipital and temporal regions of the head.

In one embodiment, the body component of the liner device is secured inside a sports helmet during use. The body component is positioned along an interior surface of the helmet inner wall. In one embodiment, the body component is form-fitted inside the helmet inner wall. In another embodiment, the body component is secured to the helmet inner wall via various suitable securing means, such as, for example, adhesive, glue, epoxy, hook and loop fasteners, rivets, etc. Specifically, the outer wall of the body component is secured to at least a portion of the helmet inner wall via application of the securing means. Depending upon the application of the securing means, the application could be a continuous layer, or a spot or discrete layer placed in a strategic location on the helmet inner wall and/or the outer wall of the body component.

In one embodiment, the body component of the device is placed within an inside of any sports helmet to help absorb contact to the user's head. Once placed on a user's head, the body component would conform to a user's head and will absorb impacts. Specifically, the body component is made from a material that can securely accommodate a fluid or gel, if necessary, but also have elasticity to allow the expansion or contraction of the body component when a user's head is pressed against it in the helmet.

In one embodiment, it should be appreciated that the body component of the head protection liner device is constructed in such a manner to match the curvature of the helmet, so that it will fit into the helmet that it is designed for. The shape and size of the body component may be adjusted to best suit the helmet's shape, size, and purpose, as well.

In one embodiment, the body component comprises an outer wall and an inner wall constructed of a silicone gel substance. In another embodiment, the body component comprises an outer wall and an inner wall which are flexibly attached to each other creating a hollow interior cavity. The interior cavity would be filled with a silicone gel substance and the outer and inner walls would be manufactured of materials that are durable, yet elastic, such as, for example, a synthetic impact gel, a soy-based impact gel, a silicone gel, etc. Generally, the body component is manufactured to be one-half inch thick but can be any suitable size as is known in the art, depending on the needs and/or wants of a user. Further, the wall thickness of the body component can also be adjusted to suit the needs of the helmet that it is designed for. The thicker the body component material, the greater the energy absorption will be, however, if it is too stiff or hard then it will contribute to head trauma in a crash impact.

Further, in one embodiment, the gel or fluid that is used for the interior of the body component, can vary in viscosity. Similarly, the thickness of the gel or fluid, can be adjusted or tuned for speed of reaction time and/or absorption. In one embodiment, the interior gel would be a non-toxic, high viscosity silicone gel. It is also preferred that the gel be a thicker liquid, so as to quickly absorb and dissipate the impact energy. Thus, the gel or fluid, incorporated inside the body component is preferably both viscoelastic and shock-attenuating.

In one embodiment, the body component can be manufactured from a non-foam elastomer, such as the class of materials known as viscoelastic polymers or silicone gels, which show high levels of damping when tested by dynamic mechanical analysis performed in the range of −50° C. to 100° C. Because the mechanical properties of the gel, can be more viscous than elastic, the gel can provide a high level of energy absorption. Some of the gels that can be used according to the present invention can be thermoplastic elastomers (elastomeric materials), such as, materials made from many polymeric families, including, but not limited to, the Kraton family of styrene-olefin-rubber block copolymers, thermoplastic polyurethanes, thermoplastic poly olefins, polyamides, polyureas, polyesters, and other polymer materials that reversibly soften as a function of temperature.

In the embodiment where an interior cavity is created, the inner and outer walls can be manufactured from any suitable durable and elastic material, such as, for example, polyurethane, latex, styrene-butadiene-rubber, acrylonitrile-butadiene, acrylonitrile terpolymers and copolymers or vinyl, etc. Desirable characteristics of the inner and outer walls of the body component include good durability, stability, and visual appearance. It is also preferred that the material of the body component have good flexibility, as indicated by a low modulus, in order to be easily moldable and flexible. In one embodiment, it is preferred that the body component be made from a soft elastomeric material, including gelatinous elastomers and cushioning materials that operate according to a principle of compression instability. The material for the body component can be any elastomeric material which tends to compress under a load and can provide cushioning upon impact. Such materials include natural and synthetic rubbers, foams, thermoplastic elastomers, polyurethane elastomers, silicone elastomers, polyvinyl chloride (PVC) elastomers, olefinic elastomers, polyamide elastomers, gelatinous elastomers which are substantially non-flowable at room temperature (below 130° F.), etc. Further, it is within the scope of the present invention to incorporate other additives, such as, fillers, pigments, surfactants, plasticizers, organic blowing agents, as stabilizers, etc., in the manufacture of the body component.

In use during an impact, head trauma, or crash, the gel inside the body component travels away from the impact zone at a rapid pace. This movement of the gel away from the impact zone distributes the incoming energy of the impact evenly through the entire helmet. This distribution of impact energy reduces the trauma to the head of the user, while distributing and dissipating the impact energy from the impact or crash. Thus, the gel within the body component reacts by traveling away from the impact zone at a rapid pace evenly and in all different directions within the body component due to the displacement and distribution of the gel.

It is understood that this impact technology would be used in several other types of helmets and/or headgear. It should also be appreciated that the head protection liner device of this invention reacts to point of impact and displaces the impact to as large a surface area as possible, thus substantially reducing the stresses created at the point of impact.

In yet another embodiment, the head protection liner device comprises a plurality of indicia.

In yet another embodiment, a method of protecting a user from head impacts and concussions during sports activities is disclosed. The method includes the steps of providing a head protection liner device comprising a body component with a silicone gel substance inside. The method also comprises securing the body component inside a sports helmet. Further, the method comprises positioning the sports helmet on a user's head, such that the body component conforms to the user's head. Finally, the method comprises utilizing the helmet and the head protection liner device while playing sports.
