ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to the field of cervical support devices which are designed to support a wearer's neck. The present invention also relates to the field of devices which support a user's neck while the user is riding and/or resting in a vehicle.
2. Description of the Prior Art
There are many devices in the prior art which attempt to address the problem of supporting a user's neck while the user is riding and/or resting and/or sleeping in a vehicle. The following twelve patents are the closest prior art of which the inventor is aware:
1. U.S. Pat. No. 3,574,397 issued to Jan Norriss on Apr. 13, 1997 for “Orthopedic Pillow” (hereafter the “Jan Norriss Patent”);

The Norris Patent discloses an orthopedic pillow. adapted for use with a seat in an automobile to allow the driver or passenger a comfortable head and neck support. Specifically, members 21 and 22 shown in FIG. 8 are slightly angular to maintain a natural neck and spinal alignment during use.
The Price Patent is a device for supporting the head and neck. It is used among other places, for supporting the head and neck during travel. Specifically, an object of the invention as set forth in Column 1 beginning on Line 48 is to have a device with a surface having a generally concave shape with respect to a vertical axis of curvature corresponding approximately to the central vertebral axis of the neck; the concave shape is fashioned so that it has symmetrical left and fight halves, opposing areas of which are designed to exert gentle pressure in the vicinity of the mastoid processes of the head, a region near the base of the head, and located at the sides thereof almost at the rear.”
The Kantor Patent is a head and neck support cushion. It is intended to be worn against a seat. It is also to be used against the shoulder blades and the lower portion of the neck. The device is horseshoe shaped and is primarily designed to support the neck but it does not go to the lower portion of the back.
The Fiore Patent is a cervical support pillow. Referring to Column 1 beginning on Line 35, the patent states that it “provides a flexible resilient pillow to support the cervical area of one using the pillow . . . ” It is adapted to receive the back of the head of the user and to fit over the shoulders of the user. Referring to FIG. 14, what is illustrated is how the device could be used when a person is seated in a chair while wearing the pillow in its wraparound arrangement by leaning back to apply pressure on the cervical spine area. However, this does not talk about the support going back to the thoracic portion of the spine.
The Pujals, Jr. Patent discloses a cervical/occipital support. This is a semi-rigid neck brace which provides posterior and lateral support. The device really functions more as a brace rather than as a pillow.
The Liu Patent discloses a protective pillow which comprises two symmetrical side panels connected by a back panel which define a receiving space therein for the comfortable support of the head of a user. The back panel has a surface which fits the back of the head. The side panels have bottom ends which terminate into hooks by which the pillow can be fastened or attached to the user's shoulders.
The Festa Patent is a therapeutic cervical pillow. The device comprises a concave pillow member having a back portion having an arcuate surface and a pair of laterally opposing arcuate side portions extending from the back portion. The arcuate side portions the back portion arcuate surface define a concavity for accepting the neck of a person for supporting the cervical spine when in a seated position. However, it does not go to the thoracic portion of the spine.
The Connolly Patent is a cervical neck support for children. The cervical neck support is a rectangular configuration and is constructed of semi-rigid foam. It is designed to essentially support the neck of the child as illustrated in the pictures.
The Fidge Patent is a support device that extends upwardly from the user's shoulder to at least a portion of the user's ears. The support includes means for varying the size and shape of the cushion with an air bladder so that dimensions can be varied during use by the individual user and configured for use by many individuals. The device is selectively positionable adjacent a person's head, neck and shoulders such that it provides a comfortable support for the person's head and neck. However, it does not extend to the thoracic portion of the spine.
The Holste Patent is a head and neck support. This is a pillow to support an individual's head and neck while seated. It is generally donut-shaped and is probably something that is probably purchased at airports.
The Seppo Patent is a design patent which is a lumbar support.
The Cothren Patent is a design patent and is a sleep support device.
While most of the prior art patents deal with supporting a user's neck while the user is riding or resting in a vehicle, none of these patents address the issue of firmly supporting the user's neck while the user is asleep in a vehicle such as an airplane and wherein certain conditions as will be discussed below occur which result in neck pain. There is a significant need for a device which supports the user's neck in a manner that the user can comfortably sleep without experiencing any neck pain upon awakening.
SUMMARY OF THE INVENTION
The present invention relates to the concept of supporting the neck during the time a passenger is asleep while riding in a transportation vehicle such as an airplane, train or car.
When an individual is asleep in the seat of a vehicle, the muscles of the entire body, in general, and the spine in particular, are in full relaxation and his/her neck and head are left without support. Frequently, as people fall asleep during a ride, their head tends to lean to one side or the other, thereby creating strain of the ligaments of the neck which result in neck pain and stiffness in the neck, often associated with headaches.
The present invention is designed to provide an apparatus to support the curve of the posterior aspect of the upper and lower portion of the neck and upper thoracic portion of the spine and behind the ears to provide support to these areas so that the head and neck will remain in a supported position while the individual is asleep. The device also provides a residing area for the skull supporting the weight of the head posteriorly. The invention holds the spine in the ideal position during sleep. The device does not support the head and neck of a passenger when awake and holding his
