This application is a continuation of U.S. patent application Ser. No. 11/569,996 filed Nov. 29, 2007, which is a National Phase of PCT Patent Application No. PCT/IL2005/000582 having International filing date of Jun. 2, 2005, which claims the benefit of priority of U.S. Provisional Patent Application No. 60/575,806 filed on Jun. 2, 2004. The contents of the above applications are all incorporated herein by reference.
BACKGROUND OF THE INVENTIONCurrently in airplanes and trains, because of space limitation, the back of seats cannot lie down, other than in premium classes of travel. Passengers therefore have to sit vertically or almost vertically for a long time, or even sleep in the vertical or near-vertical sitting position. In the vertical sitting position, the waist, spine and neck can easily get tired because they have to support the whole weight of the upper body and head. During sleep, there is lack of support, the position of the body is unstable, resulting in muscle pain, strain and paralysis.
Many prior art inventions, such as those found in the references cited below, offer methods and devices to remove some of the load caused by a long stay in an upright position.
The state of the art in the field is believed to be represented by the following U.S. Pat. Nos. 6,266,825, 6,007,156, 4,996,978, 4,834,457, 4,788,969, 3,827,716, 3,612,605, 3,531,158, 3,524,679, 3,191,599, 3,099,486, 3,063,752, 3,004,794, 2,851,033, 2,667,917, 2,667,913, 2,255,464, 1,722,205 and 284,024.
None of these inventions has yet materialized into a functional solution to the problem, possibly because the solution offered is either partial or inconvenient to use. For example, in U.S. Pat. No. 6,007,156 to G. H. Chang for “Vertical Rest Helping Method and Apparatus”, there is described a device that fixes the passenger in a predetermined position, which is not necessarily the subjective optimal position as determined by the user, and without the simple ability to change posture from time to time, or to leave and return to the seat when desired, to subjectively adjust the sitting position for user comfort, or reach the user's pockets or clothing. Furthermore, the solution proposed may impair passenger safety by fixing the passenger to his seat and reducing his evacuation speed in dangerous situations.
There therefore exists a need to provide a device and method for assisting passengers to sleep in an upright position, but which overcomes at least some of the disadvantages of prior art devices and methods.
The disclosures of each of the publications mentioned in this section and in other sections of the specification are hereby incorporated by reference, each in its entirety.
SUMMARY OF THE INVENTIONThe object of this invention is to provide a novel vest which allows passengers to sleep while sitting, but without fixing them rigidly to their seat.
In accordance with a first aspect, the present invention provides a light and portable vest which enables the user to sleep comfortably in an upright position in his seat.

In accordance with another aspect, the vest of the present invention is such that it can be readily adjusted in preparation for sleeping.
In accordance with another aspect, the vest of the present invention allows the passenger to choose his own preferred posture of sitting or sleeping and to change it from time to time.
In accordance with another aspect, the vest of the present invention allows the passenger reach his pockets, clothes and to generally move in his seat freely.
In accordance with another aspect, the vest of the present invention is also a life jacket, allowing the passenger to be prepared for dangerous situations and to evacuate his seat quickly.
There is therefore provided, in accordance with a first preferred embodiment of the present invention, apparatus for use by a subject, comprising:
-
- (i) a vest worn by the subject, the vest having a first VELCRO surface on its rear side, and attachments for attaching the vest to the upper body of the subject, and
- (ii) a seat having a back rest having a second VELCRO surface associated with its front surface, wherein the first and the second VELCRO surfaces interlock when the subject sits in the seat.
In this apparatus, the attachments are preferably such that the vest fits closely to the upper body of the subject.
In accordance with another preferred embodiment of the present invention, the vest is preferably constructed of material having rigidity, such that the vest provides support to the upper body of the subject.
Furthermore, the attachments of the vest preferably comprise straps easily connected by the subject.
In accordance with still another preferred embodiment of the present invention, the second VELCRO surface associated with the front surface of the backrest of the seat is preferably part of the front surface. Alternatively and preferably, the second VELCRO surface associated with the front surface of the backrest of the seat is part of an add-on element attachable to the backrest of the seat.
There is further provided in accordance with more preferred embodiments of the present invention, apparatus as described above, and also comprising a neck collar constructed of soft material. The neck collar may preferably be attached to the seat add-on.
In accordance with a further preferred embodiment of the present invention, the vest preferably comprises buoyancy elements such that it is also operative as a life vest.
Any of the above embodiments of the present invention are such that the subject is able to attach and detach himself from the seat without any handling of the vest or seat.
There is also provided in accordance with a further preferred embodiment of the present invention, a method of assisting a sedentary subject to sleep, comprising the steps of:
-
- (i) providing a vest having a first VELCRO surface on its rear side, and attachments for attaching the vest to the upper body of the subject,
- (ii) providing a seat having a back rest having a second VELCRO surface associated with its front surface,
- (iii) fitting the vest closely onto the upper body of the subject, such that the vest provides support to the upper body of a sedentary subject, and
- (iv) seating the subject in the seat such that the first and the second VELCRO surfaces interlock, such that the vest stabilizes the upper body of the subject against vertical and horizontal forces.
According to this method, the subject is able to attach and detach himself from the seat without a need to handle the vest or the seat. The method also preferably enables the subject to adjust his seating position to determine a most comfortable position without a need to handle the vest or the seat.
The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawings in which:

The vest of the present invention is intended to operate correctly by using it in conjunction with a seat add-on fixed to the seat, which attaches the vest to the seat in a readily adjustable and readily detachable manner, and yet supplies support to the whole back area of the vest
Reference is now made to
The preferred embodiments of the vest and seat add-on have been shown in the previous drawings and described as using a VELCRO material. The invention is also thuswise claimed. It is to be understood, though, that VELCRO is used as an example of any such similar material, having complemental parts which adhere to each when pressed together, and which are adapted for use as closure fastening components and which can be readily detached when needed, and especially separable fasteners of the hook and loop type. Alternative materials fulfilling these requirements can also be equally well used in the vest and seat add-on of the present invention.

The passenger then dons the vest and uses the straps 3 and 5 to best adjust it to his body, for snugness of fit and for comfort. At this stage, while sitting down, the passenger puts his back on the seat at the height that best distributes the load on the various parts of the body. Several attempts may be needed to determine the optimum position, but since the attachment and detachment of the vest to the seat add-on is performed so simply, this is not an arduous task. Once the optimum position has been attained, the passenger no longer has to maintain the muscle tonus in his back to hold his back straight, since the vest does so for him.
One of the advantages of this solution is that the customer can do all the adjustments himself very easily. Another advantage is that he can leave his seat at any moment during the flight and then come back and enjoy the same support from the seat. The ease with which adjustments are achieved also enables him to improve his position during the flight if, at some stage, he feels the need to do so.
