The present invention is related to the field of helmet suspension systems used inside protective helmets for military, sports, and commercial applications. Additionally, this invention is related to the field of headgear and headbands used to support eye protection visors, face shields, hearing protection earcups, respiratory protection masks. Additionally, this invention is related to the field of headgear and headbands used to support hold and support heads-up displays, night vision goggles, and communications headsets. This invention is also related to the field of headgear and headbands used to support hold and support illumination devices like flashlights as well as identification devices like blinking strobe lights and light reflective tape.
The idea of wearing objects on the head dates back to the inception of clothing itself. Throughout the ages this has been done for many reasons including warmth, fashion, and protection from the elements (e.g. sun) or from injury. With the advent of helmets in the interest of protection, approaches for securing objects, or heavier objects, to the head and the idea of “head borne” equipment was developed. Surprisingly, even though methods for securing helmets to heads still rely on different sorts of padding and strapping to provide the same function they did years ago, subtle and unique changes in the designs have resulted in vast improvements to comfort, security, stability, convenience and level of protection they offer. In more recent times, the invention of headlamps and subsequent flashlights, night vision goggles and digital displays have all required the comfortable attachment and securing of equipment to the head for purposes other than for protection.
Headgear, that is not a helmet or helmet liner, has been developed and used for the attachment and securing of non-helmet protective devices to the head. For example, EP 2 299 857 B1 is not directed to a helmet or helmet liner, but rather describes a modular, multi-component system intended for the attachment of equipment for purposes other than protection including lights, night vision goggle mounts, and Identification Friend or Foe (IFF) devices. It is dependent upon being attached to a helmet to provide its function.
U.S. Pat. No. 9,560,893 B2 shows a headgear with a spring buffered occipital cradle that may be capable of supporting the attachment of face shields, hard hats, or welding shields. U.S. Pat. No. 4,741,054 discloses a headgear system for attaching and supporting a night vision goggle device to the head without use of a helmet. Other related patents include: U.S. Pat. No. 10,441,019 (2019) Huh; U.S. Pat. No. 8,348,448 (2013) Orozco; and US 2009/0229041 (2010) Tufenkjian;
However, none of these headgear devices is designed or intended for the purpose of securely attaching a protective helmet to the head. Since the combination of features and components are not intended for protection, use of a headgear device as a way of attaching a helmet to the head instead of using a liner made specific for use in a helmet would likely compromise or reduce the protective qualities of the resulting design.
Protective helmets commonly worn by military and law enforcement, firefighters, construction workers, and rock climbers are often comprised of an outer protective shell and an inner “suspension” type liner for securing the shell to the head. Suspension liner systems use conformal straps placed under tension to literally suspend the outer shell of the helmet with a gap apart from the head. These systems are lightweight, provide good air ventilation, and the ability to adjust to many different head shapes and sizes by changing the lengths of the straps. Other protective helmets used in sports like cycling, football, hockey, and skateboarding are often comprised of an outer protective shell and an inner “compression” type liner. Compression liner systems use foam, pads, or other shock absorbing medium that are conformal or pre-shaped to match the contour of the head. These systems generally provide better support, stability and comfort than suspension liners, but are also heavier and do not provide a comparable level of ventilation. Both versions usually include a lower strap assembly designed to engage a portion of the wearer's chin or neck of the nape as well as an element that wraps around the occipital lobe of the skull. A few helmets combine both suspension and compression type liner approaches.
U.S. Pat. Nos. 3,510,879 and 7,770,239, and 9,307,802 teach that a helmet suspension system is typically anchored within the helmet shell and provides a fit of the helmet shell to the wearer's head, while providing space between the inner part of the helmet and the wearer's head to disperse and absorb at least a portion of the force of an impact to the outer shell so the full force of the impact is not transferred directly to the wearer's head.
One of the key functional aspects of a suspension type of helmet liner, is that the elements that provide the fit, attachment, and security to suspend the helmet shell apart from the head (usually webbing or strapping made of plastic and woven fibers) is that they need to conform to the shape and/or size of the head under tension when the helmet is put on. Because their materials and arrangement are designed and intended to conform, it is the shape of the head itself that determines the shape of the suspension liner system when worn. While this may be efficient at matching many different head shapes and sizes with a custom-type fit, the suspension system has deficiencies when trying to comfortably support and stabilize a helmet being subjected to forces in multiple directions at once, especially when the force includes a rotational direction.
Historically, suspension type helmet liners have utilized a headband strap affixed to the outer helmet shell to extend circumferentially around from the front toward the back of the head. These suspension liners also use other straps affixed to the headband strap and/or the outer helmet shell to extend over the top of the head. The length of these straps is always less than the circumference of the outer helmet in the region of the head they occupy. So, when a helmet is put on and these straps are put under tension by the head, they become taught and, in doing so, suspend the outer helmet shell apart from the head. These straps are typically made from materials that are formed or cut in a flat shape, which is then bent into a three-dimensional shape to match the shape of a head when installed into a helmet shell. A critical aspect of these straps is that their material and design configuration must be such that they are flexible and conformable enough to change from a relatively flat shape to a curved three-dimensional shape when attached to the outer helmet shell and put against the head. In practice, this requirement for flexibility and conformability yields approaches that are unable to hold their shape without the outer helmet shell and/or head providing some level of support.
While the characteristics are what make suspension liners comfortable, ventilated, and lightweight, these same characteristics are what prevent them from being as stable and secure as compression type liners made from materials that are more rigid and less conformable. These characteristics also necessitate that the outer helmet shell is an integral part of the system for it to properly function.
Conversely, one of the key functional aspects of compression type helmet liners is that they are pre-shaped, sized, and/or made of a soft enough material (usually some type of foam/s) that can conform to the shape and/or size of the head under compression when the helmet is put on. The outer helmet shell is not suspended above the head, but rather sits on top of the liner material under compression instead. While compression type liners are good for supporting and stabilizing a helmet being subjected to forces in multiple directions at once, they have deficiencies when it comes to long term comfort since their pre-determined shape cannot be a perfect match for most heads, and the soft conformal foams that do take a custom shape are hotter, heavier, and can cause uncomfortable pressure points on the head over prolonged periods of use.
U.S. Pat. Nos. 9,516,910 and 6,883,181 teach of compression-type helmet liners that rely on attachment to an outer rigid helmet shell. The conjunction of the liner pads being affixed to helmet shell shape having the general shape of a head is what gives these compression liner systems a headform shape. Since the outer rigid helmet shell is a predetermined shape and size, and human heads come in many different shapes and sizes, the compression-type liner system is dependent upon the softness and thickness of the pads to compensate for the difference between the shape and size of the helmet shell and the shape and size of the helmet wearer's head.
Helmets that employ both suspension and compression style components and features in the same system typically have all the drawbacks of both approaches but without most of the benefits. This is because for a suspension liner to be effective it needs to be able to suspend the head apart from the outer helmet shell. Putting any compressive liner materials in the gap between the outer shell and the head adds weight and fills up the space that would have helped with ventilation. The main added benefit of combination systems is that in this scenario, the compressive liner materials can add more impact energy absorption performance than having nothing in the gap between the head and the outer shell.
While these helmet liners are intended for attaching and securing equipment to the head, in the case of helmets, the integral combination of design features, materials and devices for attachment to the outer helmet shell are so specific that the liners cannot function independently without having the helmet shell functioning as an integral component in the system. This means that the liners are not capable of being used separately for the support and attachment of other equipment to the head.
U.S. Pat. No. 9,179,729 describes a helmet liner system intended for use inside of a helmet shell and in some configurations in combination with compressible impact absorbing liner padding. Like helmet suspension liners, it relies on tension and flexing of materials to change shape to optimally fit the head, and when used in conjunction with compressible impact absorbing pads, claims improved comfort and protection. It utilizes front, central and rear support members spaced apart from each other with attachment features for securing the support members to the inside of a helmet. A tightening mechanism is provided on the rear support and includes a rotatable knob that winds up lace that pulls the support members together. This system requires a helmet to locate, secure and provide sufficient structure for it to function and does not describe any details related to independent function without being attached to a helmet. As such, there is no explanation of how the front, central, and rear support members are secured and supported in relation to one and other, or the characteristics of the features or regions of material connecting them. Further, there is no teaching of connecting regions of material being more flexible than the support members, or the regions of connecting material being inelastic and fixable in a direction of their length, or the assembly of rigid plates being shaped and connected by the regions of connecting material so they can be pre-set to sit adjacent to and surround portions of the frontal, temporal, parietal, and occipital bone regions of a skull of a wearer.
U.S. Pat. No. 10,588,374 is another helmet liner system intended for use inside of a helmet shell and in some configurations in combination with compressible impact absorbing liner padding. It claims the same fitting and comfort benefits as other hybrid approaches and relies of a construction of multiple frame pieces working together with a lace tightening mechanism to adjust the frames size and shape relative to each other. This system demonstrates how the inner and outer frames are longitudinally affixed to slide relative to each other and are secured by a lace tightening mechanism. As a result, all of the regions of adjustment in this system are dependent upon the tension of the lace tightening mechanism, and none of the regions of this system can be set independent of each other or at permanent, non-moveable positions. Further, there is no teaching of connecting regions of material being more flexible than the support members, or the regions of connecting material being inelastic and fixable in a direction of their length, or the assembly of rigid plates being shaped and connected by the regions of connecting material so they can be pre-set to sit adjacent to and surround portions of the frontal, temporal, parietal, and occipital bone regions of a skull of a wearer.
U.S. Pat. No. 10,299,530 describes a headgear intended for securing equipment like welding shields to the head, as well as other types of protective headborne devices like helmets. It utilizes a series of forehead, top, rear, and occipital straps that are pivotably coupled together on the sides of the device to provide a means for changing the system size and shape. However, due to the fact that the different straps can freely pivot relative to one and other, they are dependent upon attachment to a helmet to locate, provide sufficient structure to secure them with respect to one and other. Since these straps are not independently secured or supported in relation to one and other, when this system is not attached to a helmet, it is limited in its ability to stabilize other headborne devices like night vision goggles or heads-up displays. There aren't any regions of material interconnecting the straps on this device, so there is no teaching of connecting regions of material being more flexible than the support members, or the regions of connecting material being inelastic and fixable in a direction of their length, or the assembly of rigid plates being shaped and connected by the regions of connecting material so they can be pre-set to sit adjacent to and surround portions of the frontal, temporal, parietal, and occipital bone regions of a skull of a wearer.
Therefore, it would be desirable then to provide a system, device and method which would address the many shortcomings of the present conventional approaches.

Embodiments of the invention, as shown and described by the various figures and accompanying text, provide a headborne attachment platform that protects the skull of a wearer and provides functionality, including the mounting of headborne devices, independent of being attached to a helmet shell.
The headborne attachment platform 10 is shown with major components of rigid plates 14 and the straps 16 of connecting material, connecting the multiple rigid plates 14 in an assembly, and that have a thickness that is less than their width or length. The comfort padding 12 is attached on the inside of the plates 14 adjacent to the head of the wearer. The straps 16 of connecting material may be more flexible than the rigid plates 14 in directions perpendicular to the thickness of the straps 16. The straps 16 of connecting material may not be stretchable (i.e. they are inelastic) in a direction that can change their length.
The assembly of multiple rigid plates 14 is shaped and connected by the straps 16 of connecting material to sit adjacent to, and surround, the portions of the frontal, temporal, parietal, and occipital bone regions of the skull of the wearer, and define an overall headgear shape and contour, and define a headband region 22 around the skull.
A tightening mechanism 20 is associated with the assembly of multiple rigid plates 14. The tightening mechanism 20 may be configured to adjust a circumference of the headband region 22 of the assembly of multiple rigid plates 16.
Referring additionally to
The mounting features may include front 26 and rear 28 mounting features as attachable mounting members that include support surfaces 29 for connection to, and suspension of, an outer helmet shell 40 around the headborne attachment platform 10. Temporal mounting features 24 may be integrated with the frontal rigid plate 60. As such, it may be appreciated that each of mounting features 24, 26, 28 may be attachable or integrated mounting features for mounting either an outer helmet shell 40 or other headborne devices such as lights, night vision, cameras, etc.
The mounting features 24, 26, 28 may define bridge features that enable the outer helmet shell 40 to be attached to it. These bridge features are designed and located to create a stand-off distance between the rigid plates 14 to keep the inner surface of the outer helmet shell 40 a distance apart from the head. This is commonly referred to as the head to shell stand-off distance. The rigid behavior of the plates 14, and the rigid plates 14 working in conjunction with the straps 16 of inter-connecting material as an assembly is what allows the headgear assembly to maintain its structure when subjected to forces exerted upon them by an outer helmet shell 40 or other devices attached to it. The assembly working in both tension and compression is what maintains the stand-off distance in all locations inside the outer helmet shell 40.
This is an upgrade over prior art approaches that only maintain the head to interior helmet shell standoff distance in some locations. By maintaining a uniform stand-off distance in all locations, helmet safety is improved since it can now provide protection in all locations, as opposed to some.
The rigid plates 14 are independently and sufficiently rigid to support and maintain their three-dimensional shape when subjected to forces exerted upon them by the outer helmet shell 40 or headborne device 42. The rigid plates 14 include attachment features 15 configured to provide for the attachment and detachment of the straps 16 of connecting material so that the rigid plates 14 are coupled together in the assembly and can be independently adjusted and set to selectable distances apart from each other using the straps 16 of connecting material. For example, the attachment features may include fasteners (e.g. screws or rivets), welds, and/or hook and loop fastening material that is attached to the rigid plates 14 as well as the straps 16 of connecting material and used for their adjustment, attachment, and detachment to the rigid plates 14. Alternatively, the straps 16 of connecting material may be passed through diving board slots, e.g. in the top rigid plate 50, which have an interference “pinch” fit which attaches and keeps the straps 16 from moving relative to the top rigid plate 50 unless the diving board slot is manually depressed.
As described, the assembly of multiple rigid plates 14 is shaped and connected by the straps 16 of connecting material such that the assembly can provide all of its functionality independent of being attached to an outer helmet shell.
One of the multiple rigid plates 14 is a frontal rigid plate 60 with a central portion 62 to sit adjacent to the frontal bone region of the skull and opposing side portions 64 to sit adjacent the temporal bone regions of the skull. The central portion 62 is relatively less flexible in directions toward and away from the skull than the side portions 64. As such, the central portion 62 of the frontal rigid plate 60 may have a hemispherical shape that is less flexible in the direction that would increase or decrease a radius of its shape relative to rotation about an axis between basic and coronal planes of the skull (see the reference planes illustrated in
One of the multiple rigid plates is a rear rigid plate 70 to sit adjacent the parietal and occipital bone regions of the skull. The tightening mechanism 20 includes an actuation mechanism 21 carried by the rear rigid plate 70 and configured to selectively cause the frontal rigid plate 60 to move closer to the rear rigid plate 70 in an area surrounding the headband region 22 of the assembly, thereby adjusting the circumference, tension, and pressure exerted upon the skull by the headband region 22 of the assembly for fitting purposes.
With additional reference to
The actuation mechanism 21 may be a dial mechanism 76 with associated lace 78 arranged through lace coupling features 79 on the rear rigid plate 70 that extend to the frontal rigid plate 60 and surround the portions of the headband region 22 of the skull of the wearer. The dial mechanism 76 is configured to selectively shorten and lengthen the lace 78 such that actuating the dial mechanism 76 adjusts portions of the rigid plates 14 around the headband region 22 to move closer to, and farther away from the skull thereby adjusting the circumference of the assembly of multiple rigid plates 14 as well as an interior volume of space where the skull sits adjacent to the assembly of multiple rigid plates 14.
In alternative embodiments, the actuation mechanism 21 may be a worm gear mechanism, a rack and pinion mechanism, and a spool and lace winding mechanism, as would be appreciated by those skilled in the art,
With reference to
As with the first embodiment, the actuation mechanism 121 as a dial mechanism 176 is configured to selectively shorten and lengthen the lace 178 such that actuating the dial mechanism 176 adjusts portions of the rigid plates 114 around the headband region 122 to move closer to, and farther away from the skull thereby adjusting the circumference of the assembly of multiple rigid plates 114 as well as an interior volume of space where the skull sits adjacent to the assembly of multiple rigid plates 114. As such, this embodiment of the headborne attachment platform 110 may be used without a chinstrap.
The rigid plates 114 are independently and sufficiently rigid to support and maintain their three-dimensional shape when subjected to forces exerted upon them by a headborne device attached to any of the headborne device mounting features 180, 181 and 182. The rigid plates 114 include attachment features 115 configured to provide for the attachment and detachment of the straps 116 of connecting material so that the rigid plates 114 are coupled together in the assembly and can be independently adjusted and set to selectable distances apart from each other using the straps 116 of connecting material. For example, the attachment features 115 may include fasteners (e.g. screws or rivets), that are attached to the rigid plates 114 as well as the straps 116 of connecting material and used for their adjustment, attachment, and detachment to the rigid plates 114. For example, a strap dial mechanism 117 may be included on the rear rigid plate 170 to loosen, tighten and adjust the strap 116 between the rear rigid plate 170 and the top rigid plate 150.
As described, the assembly of multiple rigid plates 114 is shaped and connected by the straps 116 of connecting material such that the assembly can provide all of its functionality without being attached to an outer helmet shell.
The present invention has been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claimed invention. Further, the boundaries of these functional building blocks have been arbitrarily defined for convenience of description. Alternate boundaries could be defined as long as the certain significant functions are appropriately performed. Similarly, flow diagram blocks may also have been arbitrarily defined herein to illustrate certain significant functionality. To the extent used, the flow diagram block boundaries and sequence could have been defined otherwise and still perform the certain significant functionality. Such alternate definitions of both functional building blocks and flow diagram blocks and sequences are thus within the scope and spirit of the claimed invention.
