## Title
Portable head support device

## Abstract

The portable head support device of the present invention provides comfortable support for a user's head while the user is in a sitting potion. The pillow or cushion has a v-shape on the top where a user's chin can rest so that the head cannot fall forward or sideways but will stay in a comfortable and upright position. The pillow is held in place by hook and loop fasteners located on the pillow and, for instance, on straps extending from behind the user's back and over the shoulders or wraparound supports wrapped around standard seat belts. The head support can be used in child car seats to keep a child's head in a safe and stable position while they sleep.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to and the benefit of the filings of U.S. Provisional Patent Application Ser. No. 61/847,306, entitled “Head Support,” filed on Jul. 17, 2013, and U.S. Provisional Patent Application Ser. No. 61/874,236 entitled “Head Support,” filed on Sep. 5, 2013, and the specifications thereof are incorporated herein by reference.


FIELD OF THE INVENTION
The field of the present invention is portable head supports, and more particularly, head supports that support a user's head in an upright, ergonomically correct, comfortable position, preventing the user's head from falling forward or sideways while sleeping in an upright or sitting position.
BACKGROUND OF THE INVENTION
Head support devices are widely used by travelers, children in car seats, and other people that have to sleep with their torso in an upright position, such as while sitting. However, most head supports cannot effectively prevent the user's head from tilting forward or sideways, which naturally occurs while sleeping in an upright position, or avoid putting pressure on the carotid arteries, jugular veins, or the trachea. In addition, most known devices are held in place with the aid of a neck strap that puts forward pressure on the user's upper neck region causing discomfort and possibly injuring the vertebrae. In addition, some devices cannot remain in place unless the torso of the user is leaning forward on the device. One particular problem that has not been resolved thus far is that children riding in car seats tend to fall asleep in very uncomfortable positions, e.g. with their head hanging forward, sideways, or lolling to and fro. There are no head supports in the prior art that effectively prevent this problem.
For instance, U.S. Pat. No. 5,611,601 to Cowgur discloses a rest pillow for facilitating rest for a person in a sitting position comprising an inflated flexible substantially rectangular compartment, and a strap secured to the sides of the compartment for securing the compartment to the waist of the person using it.
U.S. Pat. No. 5,645,319 to Parks, Jr., discloses an inflatable pillow on which passengers on commercial carriers may lean forward to rest their head, the pillow substantially occupying the space in front of such passengers.
U.S. Pat. No. 6,394,554 to Hingle discloses a “7”-shaped seat belt pillow which includes a neck-supporting pillow member adapted to be placed behind the head or neck while sitting in a vehicle's seat along with a secondary body pillow which is angled to approximate the angle of a buckled shoulder restraining strap and adapted to be strapped to the seat belt so it can be hugged by the user.
U.S. Pat. No. 6,625,829 to Zell discloses a chin support pillow for supporting a person's head in an upright position while sitting including a flexible member that extends around the back of the person's neck.
U.S. Pat. No. 6,860,563 to Semsch, et al, discloses a device for avoiding or limiting the tilting of the head forwards and/or to the side of a passenger sitting in a seat which has a backrest, having one or more cushion-like elements designed to completely surround the side and front sections of the neck and/or of the head of the passenger and connecting around the back of the backrest or headrest.
U.S. Pat. No. 6,973,691 to Cordova discloses a portable elongated support pillow that is crescent shaped at the top and is propped between the chin and lap of a user. There are sling style pockets to accommodate a user's arms or a strap.
Nothing in the prior art provides the unique benefits afforded by the present invention.
BRIEF SUMMARY OF THE INVENTION
Embodiments of the present invention solve the above-described problems by providing a cushion like device, or pillow, that has a v-shape on the top where a user's chin can rest with the top sides of the cushion extending upward on each side of the user's chin and jaw area to gently hold the user's head in a comfortable and upright position. This cushion can be held in place by hook and loop fasteners such as Velcro® located on the back of the cushion and on, for instance, one or more straps extending over the user's shoulders. Thus, when the cushion is temporarily fastened to the straps, the head support is held in place such that the user's chin rests on the top of the cushion and the user's head can be held in an upright position. The straps can be held in place behind the user's back, for instance they may be attached to an object or connected to each other, so long as they are secure enough to hold the cushion in place once the user rests his or her chin on the cushion.
When the user is a small child, the cushion may be held in place by attaching it to one or more seat belts, such as the two over-the-shoulder straps that are used in most child car seats. In this embodiment, two wraparound supports are wrapped around the seat belts in a way that the cushion can be attached to the wraparound supports so that the child's chin rests comfortably on the cushion. The wraparound supports have a v-shape on the bottom side so that when they are in the closed configuration and strapped around shoulder seat belts, the child seat buckle is easily accessible. Therefore, the head support device of the present invention, particularly when adapted to use in a car seat, is safer than anything in the prior art because the cushion can be easily detached from the shoulder seat belts and the buckle and be opened quickly in order to free a child from his or her car seat in an emergency.
Further, the wraparound supports can be used in other embodiments of the present invention, not just child car seats. The wraparound supports can be wrapped around any strap or belt-like object to secure the head support cushion in a position to support a sleeping person's head.
Another embodiment of the invention is one where the cushion can be thicker on the top than on the bottom. In this embodiment, the top of the cushion can be as thick as 4 inches. The fastening means is always on the thinner, bottom, portion of the cushion. Therefore, the cushion can only be installed one way, with the thick end under the chin of the user. This provides an additional safety feature because it is impossible for the cushion to accidentally press against a user's throat and cause a choking hazard (especially when the user is a child) because of the cushion's thickness.
In the preferred embodiment, the wraparound supports are made of fabric. When in the open configuration, the wraparound supports have an inside, an outside, a top side, and a bottom side. The inside comprised a center portion that is thicker than the side portions and has a surface that is composed of a grip-like fabric. The material that makes the center portion thicker can be a filling of resilient material. The opposing side portions contain opposing hook and loop fastening strips, like Velcro®. The bottom side has an approximately centered upside down v-shape.
The wraparound supports can then be moved to the closed configuration by joining the opposing side portions containing opposing hook and loop fastening strips together around the child's car seat shoulder seat belt. The thickness of the center of the wraparound support, and the fact that the center is covered in a grip-like fabric, prevents the wraparound supports from moving up or down on the seat belts. However, the wraparound supports can intentionally be installed higher or lower on the seat belts depending on the size of the child. Thus, the device of the present invention can be adjusted as the child grows.
Also, there is one strip of a hook and loop type fastener, like Velcro®, on a side portion of the outside of each wraparound support so that when it is in the closed configuration and wrapped around the shoulder seat belts, the strip of hook and loop fastener is facing away from the child. The hook and loop fastening strips of the two wraparound supports line up with the hook and loop fastening strips that are located on the back of the cushion so that the cushion can be temporarily, but securely, attached to the wraparound supports.
While a hook and loop type fastener, such as Velcro®, is the preferred means for detachably fastening the cushion to the wraparound supports or straps and for keeping the wraparound supports in the closed configuration, any type of fastening device can be used, for instance, buttons, zippers, stitching, tape, and the like, can be used as a fastening means in the present invention.
In another embodiment of the present invention, the cushion can be contained in a removable and washable cover. The cushion cover can be installed around the cushion and sealed with a zipper. The cushion cover can then periodically be removed and washed for the purpose of keeping it sanitary.
