Description

HEADREST

Field of the Invention The present invention relates to the field of vehicular accessories. More particularly, the invention relates to a headrest for use in vehicles by sleeping travelers.

Background of the Invention

Today, vehicle travel by air, sea, and/or by land, form part of almost everybody's daily life. Whether the travel is by airplane, car, bus, train, or boat, most vehicles require that the traveler be seated during the whole journey.

During travel while seated in the vehicle, a traveler may fall asleep. This is frequently the case during long trips, although it may also occur during short trips. Despite most seats having a headrest on which the traveler places the head, frequently the head drops to a side or forward due to the motion of the vehicle and/or the traveler being in a non- reclining position. Dropping of the head frequently causes the traveler to wake up. It may also cause the traveler to experience neck discomfort, and in some instances, even a sore neck. Numerous devices are known in the art which attempt to solve the problem of the head tossing around and/or to make vehicle travel more comfortable for the sleeping traveler, a few of which are described below.

US Patent No. 6122784 "TRAVEL HEADREST" relates to "A travel headrest, having first and second head cushions each having a top portion, a bottom portion and opposite sides and being elongate from the top portion to the bottom portion. The second head cushion portion includes an intermediate portion between its top and bottom portions and a flexible connecting portion interconnects the first head cushion and the intermediate portion, the top and bottom portions of the second head cushion projecting upwardly and downwardly, respectively, from the intermediate portion and from the connecting portion. The cushions may be stuffed or inflatable." US Patent No. 6648416 "HEADREST" relates to "In one embodiment, the headrest includes a support member having a center portion and an end portion which is integrally formed and which extends angularly from the center portion. A wing member is coupled to the end portion by a hinge mechanism that has sufficient friction to maintain any of a plurality of positions under a load of a human head leaning against said wing member, yet yields when a greater load is applied."

US Patent No. 6033023 "HEADREST" relates to "A portable, compact, flexible and inflatable headrest for securing to one or two vehicle seats having a separately inflatable headrest section contoured for optimal head support and a separately inflatable base for inserting in the space between adjoining seats of a passenger vehicle or in the space between the top of a vehicle seat provided with an extendible seat head rest and the bottom of the extended seat head rest to optimize rest comfort for a passenger using the headrest."

Plate fastener One object of the present invention is to fix head 40 to seat 36, without further adjustment. The way the present invention achieve the object is a detachable connection between pillow 10 and head support 16. The detachable connection is obtained when these components are already fixed in their location, i.e., pillow 10 is attached to seat 36, and head support 16 is attached to head 40. The detachability is illustrated in Figs. 1 and 2. Thus, the connection between pillow 10 and head support 16 is carried via a connector comprising components 12 and 14, which makes adjusting the vertical position adjustment unnecessary. A preferable connector is a Velcro fastener (hook and loop).

JP9168450 discloses a passenger pillow in which "Belts 6A, 6B for fastening the forehead of the user are provided on the front face of the pillow 1.", i.e., are not detachable from the pillow, in contrast to the present invention. As such, the device disclosed in this publication doesn't allow securing a pillow to a seat, wearing a head support on a user's head, and leaning the head on the pillow with no further adjusting the location of the head support with reference to the pillow. Thus, from a technical point of view, while the present invention allows a passenger to place the pillow in any height of the seat, and the head support in a desired height (preferable at the forehead) with no dependency to the user's height, the passenger's pillow of JP9168450 requires adjusting the device to a desired height.

US6047425 discloses a velvet-type fastener web which also is absent the above mentioned component. The foregoing description and illustrations of the embodiments of the invention has been presented for the purposes of illustration. It is not intended to be exhaustive or to limit the invention to the above description in any form.

Any term that has been defined above and used in the claims, should to be interpreted according to this definition.

The reference numbers in the claims are not a part of the claims, but rather used for facilitating the reading thereof. These reference numbers should not be interpreted as limiting the claims in any form.
