Crown Gravity Helix Helmet

This application is a continuation in part of application Ser. No. 18/085,444 filed on Dec. 20, 2022.

The present application refers to a protective helmet for cyclists, motorcyclists or in any type of sport, work, or activity in general who have big, kinky, coily, afro-textured type 4 or type 3 hair that does not lay flat, and that requires protection of the head with the helmet.

While a user wears a helmet, the hair is often disheveled. At the same time, in sports such as cycling, climbing and other similar ones, as well as in motor sports, caving and other professional activities, it is necessary to wear a helmet adapted to the contour of the head for protection in case of accidents. It is essential in all speed sports such as cycling, skateboarding, longboarding, mountainboarding and inline skating, among many others, that the protection of the head of the user is required.

There are many models, depending on the level of protection required, but all are based on surrounding the head with a rigid shell that can absorb the shock energy, breaking if necessary. These helmets are usually uncomfortable for the head and especially for the hair and can be hot. So, users take them off as soon as possible and are disheveled and sweaty. While there are many helmets designed to protect the head, there are hardly any helmets designed for big, kinky, coily hair. Most helmets are adapted to contour to the head and for people with flat hair; however, there are hardly any helmets that are contoured or catered to big, kinky, coily, afro-textured hair types.

There are four hair types: type 1 is straight hair, type 2 is wavy hair, type 3 is curly hair, and type 4 is coily, big, afro-textured, kinky hair. Most helmets are designed to contour to the heads of people that have type 1 and 2 hair types. Those people who have type 3 and type 4 hair types find themselves with an added discomfort. Since most helmets are designed to adapt to the heads of people with type 1 and 2, straight, wavy, and flat hair, they do not consider the needs of people with hair types 3 and 4. Therefore, those with type 3 and 4 hair types are often uncomfortable wearing a helmet and/or avoid wearing a helmet altogether.

The present invention solves these problems by ensuring that those with type 3 and type 4 hair types can wear a helmet that contours to their head and hair while protecting them from severe injury and also protecting their hair from friction and damage

The Crown Gravity Helix Helmet is a safety helmet specifically designed to address the needs of individuals with voluminous, kinky, coily, and textured hair, particularly those with hair types 3 and 4. It accommodates the volume and structure of non-flat hairstyles such as ponytails, buns, and afros, providing both protection and comfort. The helmet is intended to reduce the risk of hair damage caused by friction, compression, or improper fit. Hair is generally classified into four types: type 1, type 2, type 3, and type 4.

Type 1 hair is straight, typically lies flat against the scalp, and does not naturally curl. It tends to be naturally oily and may vary in volume or wave, but retains a straight texture. Type 1 hair is often longer in length.

Type 2 hair is wavy and lies relatively flat, falling between straight and curly in texture. It ranges in length, often tending toward longer styles. Type 2 waves include loose, stretched S-shaped waves; shorter, more defined S-waves; and waves with some spiral characteristics, though the overall appearance remains flat.

Type 3 hair is curly, typically forming S-or Z-shaped patterns. It generally has medium length and includes curl types such as large, loose curls, bouncy ringlets, and tight corkscrew curls. Type 3 hair does not lie flat, has high volume, and is prone to frizz and damage if not properly maintained.

Type 4 hair is tightly coiled and generally shorter in length. It produces little natural oil, is highly fragile, and has high density. It also exhibits significant shrinkage when wet and is more susceptible to breakage than other hair types. Curl patterns in type 4 hair range from tightly coiled S-curls to Z-patterned and kinked curls with less defined structure.

Most currently available helmets are designed to accommodate hair types 1 and 2, which are typically straight or wavy, lie relatively flat against the scalp, and are less prone to damage. These helmet designs generally do not incorporate features or technologies that address the needs of hair types 3 and 4, which are characterized by greater volume and increased susceptibility to damage.

By way of example, an existing helmet known as a “protective helmet with hair-entraining aperture,” developed in 1996, is designed primarily for individuals with long, straight hair. This helmet includes a small aperture intended to accommodate hair types with lower density and volumes specifically, type 1 and type 2 hair, which typically lies flat and is less voluminous. However, this design is not suitable for individuals with type 3 or type 4 hair, which is characterized by higher density, greater volume, shorter length, and tightly coiled or kinky textures. These hair types require a larger aperture to accommodate their structure. Furthermore, an effective helmet design for types 3 and 4 would not only require a larger opening but also an aperture featuring advanced technology that would still allow for the opening or aperture to contract to prevent penetration through the opening or aperture.

The Crown Gravity Helix is an invention comprising a helmet configured to protect the head, hairline edges, and scalp or root areas of the hair. The helmet further includes one or more expandable and contractible openings designed to accommodate and protect both the head and the ends of the hair.

The helmet comprises multiple layers and components, beginning with the outer shell. The outer shell may be constructed from materials commonly used in helmet manufacturing, such as acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), or polycarbonate (PC). This layer serves to protect the head and internal components of the helmet by preventing penetration from external objects and dispersing impact forces over a broader surface area, thereby reducing the force transmitted to the inner liner and the wearer's head.

The second layer is a shock-absorbing foam liner positioned directly beneath the outer shell. This layer may be composed of materials such as expanded polystyrene (EPS), multi-directional impact protection system (MIPS), expanded polypropylene (EPP), or similar. Its primary function is to absorb and dissipate impact energy transferred from the outer shell, thereby minimizing the force experienced by the wearer's head.

The third layer is a comfort liner, typically composed of thin padding and moisture-wicking fabric. This layer provides a secure and comfortable fit for the wearer and enhances overall usability.

Within the comfort liner layer we will incorporate an improved liner system in the Crown Gravity Helix Helmet that support type 3 and 4 hair types, and will includes three key elements: an elastic silk or satin edge band to protect hairline areas, a second full-head silk or satin liner for comfort and hair protection, and a third impact-absorbing foam padding liner that conforms to the helmet, stabilizes the helmet, prevents pressure points, and anti-slippage features.

Additional layers of foam or comfort padding may be included as necessary to ensure optimal protection and support for both the head and hair, particularly for users with high-volume or sensitive hair textures.

In addition to the aforementioned structural layers, the helmet includes a ventilation system integrated into the outermost shell to promote airflow and assist with cooling during use.

The helmet may also be equipped with detachable and adjustable visors, available in various styles and colors. The visors are designed to shield the eyes and provide protection from sunlight and other environmental elements.

A retention or fit adjustment system is positioned at the rear of the helmet, enabling the wearer to customize the fit according to their head size and hairstyle. The placement of this system may be configured in coordination with the location of the expandable and contractible openings to ensure optimal functionality and comfort.

Further, the helmet comes equipped with an essential chin strap system. The chin trap system adds an additional mechanism to keep the helmet and the additional liners of the helmet secure and in place. The chin strap system should be adjustable so as to make the strap ride close to the chin and skin, not to lose or be too tight, but close enough to the skin and chin to ensure the helmet and additional liners of the helmet stay securely in place.

The helmet includes one or more expandable and contractible openings located on various areas of the outer shell, including the top and the lower rear portion of the helmet. These openings are designed to accommodate and protect the ends of the hair while maintaining helmet integrity. Each opening comprises three primary components: (1) a bottom layer made of silk or satin that can expand and contract; (2) a top shell layer composed of the same material as the helmet's outer shell (e.g., ABS, PVC, or PC) that is also capable of expansion and contraction; and (3) a drawstring mechanism that enables manual adjustment of both the inner silk/satin layer and the outer shell layer.

An alternative to the drawstring mechanism is an electronically controlled adjustment system, activated via a button, which allows the openings to expand or contract automatically to permit hair to pass through. In some embodiments, the electronic version may further include tracking or location technology to assist users in locating the helmet if misplaced.

Like reference numerals indicate similar parts throughout the figures.

The present disclosure may be understood more readily by reference to the following detailed description of the disclosure taken in connection with the accompanying drawing figures, which form a part of this disclosure. It is to be understood that this disclosure is not limited to the specific devices, methods, conditions, or parameters described and/or shown herein, and that the terminology used herein is for the purpose of describing particular embodiments by way of example only and is not intended to be limiting of the claimed disclosure.

Also, as used in the specification and including the appended claims, the singular forms “a,” “an,” and “the” include the plural, and reference to a particular numerical value includes at least that particular value, unless the context clearly dictates otherwise. Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It is also understood that all spatial references, such as, for example, horizontal, vertical, top, upper, lower, bottom, left and right, are for illustrative purposes only and can be varied within the scope of the disclosure.

The present invention provides a helmet solution that merges protective functionality with tailored comfort for individuals with voluminous, texture, curly, or afro-textured hair. With specific reference toof the drawings, the structure and features of the various embodiments will be detailed. This disclosure sets forth how the invention accommodates the wide variability in hair types such as hair type 3 and 4, and configurations while delivering performance suitable for high-impact sports, transportation use, and professional work environments.

illustrates a perspective front view of helmet. The helmet comprises a generally rounded outer shell, designed to encase the human head and provide an external barrier against impact. The outer shellis preferably composed of impact-resistant material such as high-density polycarbonate, ABS plastic, or a composite fiber resin blend. The design of the outer shell includes curvature optimized to diffuse physical energy while maintaining aesthetic balance.

Positioned at the top center of the helmet is an opening, shaped oval or circular, which serves as a hair passageway. This opening is designed to receive a puff, bun, or ponytail of the user's hair and allows for the passage of high-volume hairstyles without forcing the hair to flatten against the scalp. The outer rim of the openingis reinforced by a surrounding bottom layer silk-based band. The bandis elastic, stretchable, and designed to gently accommodate the dynamic shape of the hairstyle while reducing friction and static buildup. Silk is selected for its low surface friction, hypoallergenic properties, and thermal neutrality. The outer room of openingis reinforced also by a surrounding top layer over the silk band that is composed of the same material as the outer shell, such as impact-resistant material such as high-density polycarbonate, ABS plastic, or a composite fiber resin blend.

Adjacent to the opening are front ventilation ports. These are elongated or circular apertures that serve to draw in fresh air during motion. The airflow is directed over the scalp and through the hair, mitigating the overheating and perspiration problems typical for users with dense or thick hairstyles. These ports are strategically shaped to enhance airflow velocity, assisted by the internal channeling provided by the liner structure.

The front face of the helmet includes molded ergonomic shapesthat improve the helmet's aesthetic appeal and provide anchor regions for modular attachments such as visors, cameras, or lights. These shapes also subtly contribute to the diffusion of impact forces and to redirect water away from the top vent during wet conditions.

Beneath the outer shell, the internal helmet structure begins with an foam impact-absorbing liner. This foam liner conforms closely to the user's cranial shape and is typically constructed from energy-absorbing foam, such as EPS (expanded polystyrene), EPP (expanded polypropylene), or a thermoplastic elastomer foam. This layer is rigid yet forgiving, designed to compress under sudden forces to protect the skull.

Directly beneath the impact-absorbing liner, a comfort liner,is a secondary linerA made of woven or natural silk. This comfort liner, is composed of three elements: an elastic silk or satin edge band to protect hairline areas, a second full-head silk or satin liner for comfort, hair protection, and provides a hair-and skin-friendly interface for the user, and a third impact-absorbing foam padding liner that conforms to the helmet, stabilizes the helmet, prevents pressure points, and anti-slippage features. Unlike synthetic materials which may generate heat and static, silk maintains a neutral charge and offers a breathable, comfortable cushion against the scalp. This layer protects the hair from breakage, friction-induced tangling, and moisture retention.

A round the bottom interior rim of the helmet, there is a silk-lined elastic band that is a part of the comfort liner. This band gently hugs the edge of the scalp, especially the hairline, which is a sensitive and damage-prone region for textured hair types. This bandnot only protects the hairline from wear but also secures the comfort liner, made of silk and foam,A andin position, preventing them from shifting as the user moves.

At the base of the helmet is a strap system, anchored to both sides of the shell. The strap is composed of satin-lined polymer or coated fabric that is gentle on the neck and chin. It includes a buckle closure with multiple adjustment points for users with different jaw widths or chin structures. An optional chin cup may also be integrated for additional comfort.

Turning now to, the rear perspective view of the helmetis depicted. The outer shellcontinues toward the rear, embracing the silk-lined opening. This continuity ensures structural strength and protection across the entire skull. Additional ventilation portsandare shown at either side of the rear quadrant. Portsandare arranged vertically along the midline to allow efficient heat and moisture escape from the scalp area.

illustrates another embodiment of the helmet, showing dual hair openingspositioned on the top front area. This configuration supports hairstyles such as double buns, twin puffs, and high-section braids. Each openingis rimmed with a silk-lined elastic bandthat adjusts to accommodate different diameters of hair volume. The openingscan be pulled open via a stretch mechanism or compressed shut when not in use.

The helmet again includes front ventilation portsand similar structural enhancements. Beneath the outer shell lies a multilayered protection and comfort system. An outer impact linerfunctions similar to linerin. Directly below is a full silk linerA, protecting the scalp from rubbing and irritation. Encircling the internal rim is a silk band, acting as a stabilizer and a comfort cushion for the edge of the head and hairline.

The strap assemblyis integrated on the lower shell edge, featuring adjustable slide rings, quick-latch components, and optional padding at contact points. The combination of the dual openings, silk liners, and ergonomic shell design enables the user to confidently wear the helmet for extended periods without compromising hairstyle or head comfort.

In, the back view of the dual-opening helmet is illustrated. The rear continues the external shellconstruction and provides a clear view of openingsand silk-lined bands. These bandsare wide enough to accommodate significant hair volume without generating tight pressure. Their elasticity allows them to stretch and rebound repeatedly, preserving their function over many uses.

Additional configurations may involve interchangeable modular silk liners of varying thicknesses for hair types that require more room or more compression. The liners may include perforations for better breathability or may incorporate padding in key pressure zones, such as the crown and nape.

In another embodiment, the helmet openings may include closures, such as silk flaps, elastic drawstrings, or overlapping panels that allow the user to close the openings when not in use. This provides versatility for users who may alternate between wearing their hair out or tied in styles that do not require top access.

Other variations may involve treating the silk liner with antimicrobial, anti-odor, or moisture-wicking coatings to extend hygiene and freshness over longer periods of use. The foam liner may also include channels to direct air circulation and vent hot air away from high-friction zones.

For users engaged in sports like skateboarding, BMX, or mountain biking, the helmet may be paired with optional mounts or visors that do not interfere with the integrity of the hair openings. The outer shell may also include slots or covers for LED lights or reflectors.

A more advanced embodiment includes a detachable rear panel that reveals a larger vertical slot, intended to accommodate long braids or locks. This slot is lined with silk and includes a cover flap that closes via magnets or Velcro.

Another variation allows the user to select silk liners of different colors or textures to suit aesthetic preferences or coordinate with apparel.

The combination of these structural, material, and ergonomic features addresses a long-unmet need for head protection in communities with natural, voluminous hair. It empowers users to engage in physical activity, transportation, and professional safety contexts without sacrificing personal comfort, hair health, or safety standards.

Accordingly, while specific embodiments have been described and illustrated, modifications and alterations may be made without departing from the spirit and scope of the invention as defined by the appended claims.
