## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is related to and claims priority benefits from U.S. Provisional Application Ser. No. 61/459,044, filed on Dec. 6, 2010, entitled “NECK SUPPORT.” The '044 application is hereby incorporated in its entirety by this reference.


FIELD OF THE INVENTION
The field of the invention relates to passenger seats. More specifically, it relates to passenger seats with enhanced neck and head support for the passenger.
BACKGROUND
In various modes of transportation, a passenger may be subjected to a passenger seat for various lengths of time. In airline travel, for example, it is not uncommon for a passenger to be seated in a passenger seat for multiple hours. During such time, it is beneficial to the passenger's overall health if the passenger's neck and head are properly supported.
Traditional passenger seats, with fixed orientation positions, cannot be adequately adjusted to provide each passenger with the head or neck support (or comfort level) that he or she requires. As a result, passengers typically bring personal items, such as pillows and blankets, on board to achieve such support. These items may be quite cumbersome, however, and typically intrude into the personal space of another passenger.
Thus, it may be desirable to provide passenger seats with easily adjustable structures to support each passenger's neck and/or head, while eliminating the need of personal items to achieve a similar result.
SUMMARY
Certain embodiments of the present invention include passenger seats comprising a seat back support and a neck support structure comprising a headrest coupled to the seat back support and at least one wing pivotally coupled to the headrest, wherein the at least one wing is configured to rotate downwardly from a stowed position to a first deployed position, and wherein the at least one wing is also configured to rotate laterally from the stowed position to a second deployed position.
In some embodiments, the neck support structure may comprise a first wing and a second wing.
In some embodiments, the at least one wing may be configured to rotate upwardly from a stowed position to a deployed position.
In some embodiments, a cover may be removably coupled to the at least one wing.

DETAILED DESCRIPTION
Embodiments of the invention provide passenger seats with an adjustable support structure for a passenger's neck or head. While the passenger seats are generally discussed for use with aircrafts, they are by no means so limited. Rather, embodiments of the passenger seats may be used in connection with any mode of transportation or otherwise as desired.
FIGS. 1-4 illustrate embodiments of a passenger seat 100. In these embodiments, the passenger seat 100 may comprise a seat back support 102 and a neck support structure 104. The passenger seat 100 may also comprise seat accessories, including but not limited to at least one cushion 106, at least one armrest 108, at least one passenger belt 110, and at least one leg 112. The passenger seat 100 may also exist within a passenger seat assembly 114 of one or more passenger seats 100. The passenger seat assembly 114 may also comprise seat accessories, including but not limited to the cushion 106, the armrest 108, the passenger belt 110, and the leg 112.
The seat back support 102 provides a foundation, form, and shape for the passenger seat 100 and provides support to a passenger's body. The seat back support 102 may have any suitable seat-like shape, such as the embodiments illustrated in FIG. 1. Throughout embodiments, the dimensions of the seat back support 102 may vary as needed. In some embodiments, the seat back support 102 may be linear. In some embodiments, the seat back support 102 may be curvilinear. The seat back support 102 may be formed of materials including but not limited to composite plastics, aluminum, stainless steel, other metallic materials, composite materials, or other similar materials. In some embodiments, the passenger belt 110 may be coupled to the seat back support 102. In some embodiments, the cushion 106 may be coupled to the seat back support 102. The cushion 106 may include any suitable cushion material that provides the desired amount of comfort and support to the passenger.
The neck support structure 104 is capable of providing support to a passenger's neck and head while the passenger utilizes the passenger seat 100. The neck support structure 104 may comprise a headrest 116 and at least one wing 118.
The headrest 116 provides support for the passenger's head and/or neck. The headrest 116 may be coupled to the seat back support 102 and may serve as a foundation for the wing 118. In some embodiments, the headrest 116 may be coupled to the seat back support 102 by a variety of mechanisms including but not limited to an adhesive, bolts, fasteners, screws, and other coupling mechanisms. In other embodiments, the headrest 116 and the seat back support 102 may be integrally formed so that the headrest 116 remains at a fixed position relative to the seat back support 102. In yet other embodiments, the headrest 116 may be pivotally coupled to the seat back support 102.
The headrest 116 may have any suitable cross-sectional shape including but not limited to circular, rectilinear, trapezoidal, other similar polygonal shape, or any irregular shape. In some embodiments, it may be suitable for the length and width of the cross-sectional shape of the headrest 116 to have differing dimensions. The depth of the headrest 116 may also vary throughout embodiments. The headrest 116 may be formed from a variety of materials, including but not limited to composite plastics, aluminum, stainless steel, other metallic materials, composite materials, or other similar materials. In some embodiments, a cushion 120 may be coupled to the headrest 116. The cushion 120 may include any suitable cushion material that provides the desired amount of comfort and support to the passenger.
The wing 118 is pivotally coupled to the headrest 116 so as to provide support for the passenger's head and/or neck. In some embodiments, the wing 118 may be coupled to the headrest 116 by a variety of mechanisms, including but not limited to hinges, fasteners, rods, and other pivotally coupling mechanisms. In some embodiments, the wing 118 may be pivotally coupled to the headrest 116 via a friction hinge, which relies on a constant friction force within the hinge to hold a position until an excessive torque is applied to overcome the hinge resistance torque and move the wing 118 to another position within its range of motion. As a result, the wing 118 may only be adjusted by direct, intentional force or manipulation by the passenger. In some embodiments, the friction force between the wing 118 and the headrest 116 will likewise prevent unintentional adjustment of the wing 118. In other embodiments, the wing 118 may be secured into place after adjustment by a variety of manners, including but not limited to a locking mechanism.
The position of the wing 118 may vary between a stowed position and a deployed position. In a stowed position, as illustrated in FIG. 2, the wing 118 is positioned approximately flush with a surface 122 of the headrest 116 or a surface 123 of the seat back support 102. In a deployed position, the wing 118 may be rotated some distance away from the surface 122 or the surface 123 to any suitable deployed position, ranging from a stowed position (as shown in FIG. 2) to a fully deployed position. In some embodiments, the wing 118 may rotate up to 90 degrees or less away from the surface 122 or the surface 123. In other embodiments, the wing 118 may rotate beyond 90 degrees.
In some embodiments, as illustrated in FIG. 3, the wing 118 may be coupled to the headrest 116 in a manner such that the wing 118 may rotate downwardly from a stowed position to a deployed position. In some embodiments, the wing 118 may be coupled to the headrest 116 in a manner such that the wing 118 may rotate upwardly from a stowed position to a deployed position. In some embodiments, as illustrated in FIG. 4, the wing 118 may be coupled to the headrest 116 in a manner such that the wing 118 may rotate laterally from a stowed position to a deployed position. In some embodiments, the wing 118 may be coupled to the headrest 116 in a manner such that the wing 118 may rotate downwardly or laterally from a stowed position to a deployed position. In some embodiments, the wing 118 may be coupled to the headrest 116 in a manner such that the wing 118 may rotate upwardly or laterally from a stowed position to a deployed position.
In some embodiments, the neck support structure 104 may comprise more than one wing 118. For example, in the embodiments illustrated in FIGS. 1 and FIGS. 2-4, the neck support structures 104 comprise two wings 118. In other embodiments, the neck support structure 104 may comprise three or more wings 118. In some embodiments, the wings 118 may be independent from one another, such that either wing 118 may operate independently of the other wing 118. In some embodiments, the wings 118 may be integrally formed, or otherwise connected to one another such that either wing 118 cannot rotate independently of the other wing 118 in at least one direction.
In some embodiments, two or more wings 118 may be connected by a connecting member 128. For example, in the embodiments illustrated in FIGS. 1 and FIGS. 2-4, the two wings 118 are connected by the connecting member 128 such that the first wing 118a cannot rotate downwardly independent of the second wing 118b. In some embodiments, either wing 118 may be pivotally coupled to the connecting member 128 in a manner such that either wing 118 may rotate independently of the other wing 118 in at least one lateral direction. The wing 118 may be coupled to the connecting member 128 by a variety of mechanisms, including but not limited to hinges, fasteners, rods, and other pivotally coupling mechanisms. In some embodiments, the wing 118 may be pivotally coupled to the connecting member 128 via a friction hinge, which relies on a constant friction force within the hinge to hold a position until an excessive torque is applied to overcome the hinge resistance torque and move the wing 118 to another position within its range of motion. As a result, the wing 118 may only be adjusted by direct, intentional force or manipulation by the passenger. In some embodiments, the friction force between the wing 118 and the connecting member 128 will likewise prevent unintentional adjustment of the wing 118. In other embodiments, the wing 118 may be secured into place after adjustment by a variety of manners, including but not limited to a locking mechanism.
The shape of the wing 118 may vary throughout embodiments. Moreover, in embodiments in which more than one wing 118 exist, the shape of each wing 118 may also vary within the embodiments. The wing 118 may have any suitable cross-sectional shape including but not limited to circular, rectilinear, trapezoidal, other similar polygonal shape, or any irregular shape. In some embodiments, it may be suitable for the length and width of the cross-sectional shape of the wing 118 to have differing dimensions. The wing 118 may be formed from a variety of materials, including but not limited to composite plastics, aluminum, stainless steel, other metallic materials, composite materials, or other similar materials. In some embodiments, the wing 118 may be formed from a variety of flexible materials, which may allow the shape of at least a portion of the wing 118 to be manipulated by the passenger. Such materials may include but are not limited to wire, aluminum, other malleable metallic materials, composite materials, plastics, or other similar flexible materials. In some embodiments, a cushion 124 may be coupled to the wing 118. The cushion 124 may include any suitable cushion material that provides the desired amount of comfort and support to the passenger.
In some embodiments, a cover 126 may be removably coupled to the wing 118. The cover 126 may be formed from a variety of materials, including but not limited to any number of fabrics, composite plastics, composite materials, or other similar materials. The cover 126 may provide for repeated, hygienic use of the wing 118. For example, the cover 126 may be coupled to the wing 118 for use by a first passenger. After completion of use of the wing 118 by the first passenger, the cover 126 may be removed and replaced with a new, clean cover 126 for use by a second passenger. The cover 126 may be removably coupled to the wing 118 by a number of mechanisms including but not limited to an elastic mechanism, an adhesive, a compression mechanism, and other similar mechanisms.
In use, a passenger may utilize the neck support structure 104 to support the passenger's head or neck. For example, in the deployed position illustrated in FIG. 3, the wings 118 provide direct support to a passenger who wishes to tilt or lean his or her head or neck. The passenger may sit in the passenger seat 100, downwardly rotate the wings 118 to the illustrated deployed position, then tilt his or her head or neck to the right or left and find it supported by either wing 118. Such support may eliminate the need for a personal pillow. Similarly, in the alternative deployed position illustrated in FIG. 4, the wings 118 provide direct support to a passenger who wishes to tilt or lean his or her head or neck to the right of left. The passenger may sit in the passenger seat 100, laterally rotate the wings 118 to the illustrated deployed position, then tilt his or her head or neck to the right or left and find it supported by either wing 118. Notably, the wings 118 of the embodiments illustrated in FIG. 4 are connected via the connecting member 128, such that each wing 118 may rotate laterally independent of the other wing 118.
In some embodiments, the passenger may adjust the wing 118 and neck support structure 104 by physically grasping the wing 118 and manually rotating the wing 118 some distance away from the surface 122 or the surface 123. In other embodiments, the neck support structure 104 may be electronically equipped such that the passenger may rotate the wing 118 some distance away from the surface 122 or the surface 123 via an automated control mechanism.
The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention.
