No. 15/068,385 claims benefit to provisional patent application No. 62/300,406, entitled “Headrest for Head and Neck”, filed Feb. 26, 2016, the contents of each of which are incorporated by reference in their entirety for all purposes.


FIELD OF THE INVENTION
Embodiments of the present disclosure are related to headrests for the head and neck, and improvements thereof.
BACKGROUND OF THE INVENTION
There are over 300 million business travelers worldwide who fly several times a year. According to the United States Department of Transportation, since 2010, there are over 600 billion domestic airline passengers every year, and over 150 billion international airline passengers every year (Bureau of Transportation Statistics T-100 Market data, Passengers www.transtats.bts.gov/ 17 Feb. 2016). Traveling can take up a large portion of a person's day. Travelers may choose to rest or sleep during traveling, but seating in commercial vehicles may not allow for restful sleep or comfort. Seats found in a vehicle, such as an airplane, automobile, bus, or train, can be uncomfortable for a passenger, as vehicle seats offer limited support for a user's head and neck.
SUMMARY OF THE INVENTION
Traditional pillows are often cumbersome during travel (e.g. during commercial airline travel, traditional pillows may be too large to fit in a carry-on luggage compromising space for other luggage). Existing travel pillows are often bulky, taking up much of a traveler's limited carry-on luggage space or size allowance. With limitations imposed on the size or number of items a person may carry, a traveler may have to make a decision whether or not to sacrifice personal comfort, because a bulky travel pillow occupies too much of the limited size allowance. Certain travel pillows are volumetrically inefficient and occupies too much of the limited space in a luggage-piece.
Existing travel pillows are supposed to support the head and neck. However, many of the existing travel pillows do not properly fit within a head and neck region and do not provide support because of the improper fit. Improper fit leads to lacking full support of the neck. In certain cases, travel pillows may shift while a user is sleeping. The shift results in a travel pillow in an incorrect position, causing strain to a user's neck.
Furthermore, existing travel pillows also fail to support the lateral alignment of the neck because they fail to provide adequate structural support. Most pillows have beaded inners, or foam that compress during use, thus failing to provide the structural rigidity needed to keep the upper neck vertebrae (C1-C17) aligned.
Other existing travel pillows are inflatable. Inflatable travel pillows, however, are uncomfortable, as they are constructed of unbreathable material and fail to provide consistent support, comfort of use, breathability and consistent support. Because inflatable travel pillows require an air-tight bladder, they cause discomfort due to a lack of ventilation that non-deflatable solutions may provide. Furthermore, the air-tight bladder may be punctured, creating an inconsistent and uncomfortable use if deflated.
Accordingly, certain embodiments of the present invention relate to a supporting apparatus for the neck, head, and shoulders, providing consistent and comfortable support. Certain embodiments of the invention comprise a C-shaped form, intended to interface with a user's shoulders, neck, and head. In certain embodiments, the apparatus interfaces with the occiput region of the head, providing equal spacing between the left shoulder structure and the head and the right shoulder structure and the head. In doing so, the supporting apparatus minimizes lateral neck flexion to provide the structural rigidity needed to keep the upper neck vertebrae in alignment. In certain embodiments, the shape of an apparatus supports the head and the cervical vertebrae C1-C7. Certain embodiments have protruding features and recessed areas that are intended to support the skull, including the occipital bone, and supporting the shoulder blades of a user. In certain embodiments, protruding features are found on an upper portion and a lower portion of an apparatus.
In certain embodiments, the ergonomic symmetrical shape, such as the location of the protruding features, help to support the occiput of the head and the shoulder of a user. In certain embodiments, an upper portion and a lower portion are symmetrical about a horizontal plane. In certain embodiments, a left side and a right side are symmetrical about a vertical plane. While traditional travel pillows may have a top/bottom orientation for proper function, in certain embodiments, the symmetry found in an apparatus allows a user to more easily use the apparatus, without having to correctly orient the apparatus prior to use.
Certain embodiments of the invention comprise a foam core having a semi-rigid characteristic to support the occipital bone of the skull and the shoulder. Certain embodiments have a C-shaped form, where the vertex or center region of the C-shaped form supports the back of the neck. An opening at the center region of an embodiment of the apparatus provides airflow to the back of the neck. A shell piece attaches to an opening of an embodiment of the apparatus, and a bezel piece further attaches to a shell piece in certain embodiments. In certain embodiments, a shell piece or a shell piece and a bezel give an apparatus torsional rigidity. In certain embodiments, a shell piece, or shell piece and bezel act as a support frame giving an apparatus rigidity. In certain embodiments, structural integrity provided by a frame provides the apparatus rigidity, while a flexible core provides comfort.
Certain embodiments of the invention relate to a supporting apparatus having a size smaller than many devices intended for supporting the neck, head, and shoulders. Certain embodiments have a size that is approximately 80% smaller than traditional travel pillows. A smaller size allows certain embodiments to occupy a smaller volume, allowing greater portability. Certain embodiments have protruding features allowing a smaller size but providing the same or greater support and thus better neck alignment than larger travel pillows.
Certain embodiments are an improvement upon traditional travel pillows. Unlike traditional travel pillows certain embodiments of the invention have a smaller profile, providing the benefit of supporting the head and neck while occupying a smaller volume. Furthermore, certain embodiments of the invention have a C-shaped form that simultaneously supports the back of one's head, such as the occiput, and the base of the neck. In addition, in certain embodiments, the overall form of the apparatus is sold as a single piece unit, requiring less set-up as compared to other multi-piece travel pillows. Furthermore, certain embodiments are sold as a single piece unit, requiring less set up compared to traditional travel pillows that require inflating, molding or shaping, bending, or strapping.
Certain embodiments have a housing comprising a material to maximize a traveler's comfort. Materials that are breathable, moisture wicking, soft, flexible, etc. are used in certain embodiments to increase a traveler's comfort when using certain embodiments of the present invention. In yet another embodiment, the present invention has an opening at a center region to improve air-flow to the neck. Certain embodiments have features that promote the comfort of a user. In certain embodiments, an apparatus can be heated and/or cooled for the comfort of a user. In certain embodiments, an apparatus includes a heating element, for example, a heating coil attached to a battery. In certain embodiments, a heating element, for example, heats a portion of an apparatus, such as a core piece, or a housing, as to provide comfort for a user. In certain embodiments, a heating element or a cooling element are integrated with an apparatus. Certain embodiments of an apparatus incorporate one or more magnets. It will be appreciated that magnets are incorporated in order to increase blood flow, for example, to the head to relieve pressure and reduce tension. Certain embodiments of an apparatus incorporate a vibrating feature. It will be appreciated that vibrating features, such as a vibrating motor, are incorporated in order to provide a massaging effect such as to relieve pressure and reduce tension. It will be appreciated that a battery and switch are used with a heating element, cooling element, or vibrating feature. Certain embodiments use a rechargeable battery.
Certain embodiments of an apparatus are foldable as to become a more compact form. Certain embodiments that are foldable are able to fold along a vertical plane. Folding, in certain embodiments, is accomplished with hinges located on a shell piece. Folding, in certain embodiments, is accomplished with hinges located on a bezel. In certain embodiments, hinges located on a shell piece and a bezel allow folding an apparatus such that the lateral supports are brought together. In certain embodiments of an apparatus that are foldable, a core piece has a recess that allows folding of an apparatus.
