Method and means for facilitating rest for a person in a sitting position

The rest pillow comprises an inflated flexible substantially rectangular compartment having top, bottom, front and rear portions and opposite side portions. An inflation port is located in the compartment to selectively inflate or deflate the compartment. A strap is secured by its ends to the sides of the compartment for securing the compartment to the waist of the person using it. A plurality of baffles extend from the front interior of the compartment to the rearward portion thereof to prevent the compartment from becoming substantially distorted when the person using the pillow rests his or her head on the top portion thereof. The method of the rest pillow comprises placing an inflated substantially rectangular flexible compartment on the lap of a sitting person, causing the person to lean forward to rest the person's head and arms on the top of the compartment to bind the compartment between the head and arms, and the lap of the person, and to provide resting support for the person's head and arms.

BACKGROUND OF THE INVENTION 
Resting and sleeping while in a sitting position on an airplane, 
automobile, or the like, is difficult for many and impossible for some. 
This is principally because there is no adequate means for supporting a 
person's head and shoulders in a stable position while the person is 
sleeping. 
It is therefore a principal object of this invention to provide a method 
and means for facilitating rest and sleep for a person in a sitting 
position primarily within a traveling vehicle. 
A further object of this invention is to provide a method for facilitating 
rest for a person in a sitting position which can be easily and quickly 
implemented. 
A still further object of this invention is to provide a means for 
facilitating rest for a person in a sitting position which is compact and 
easily stored when not in use. 
A still further object of this invention is to provide a means for 
facilitating rest for a person in a sitting position which is safe and 
which easily accommodates the space requirements surrounding the seat in 
most vehicles. 
These and other objects will be apparent to those skilled in the art. 
SUMMARY OF THE INVENTION 
The rest pillow of this invention comprises an inflated flexible 
substantially rectangular compartment having top, bottom, front and rear 
portions and opposite side portions. An inflation port is located in the 
compartment to selectively inflate or deflate the compartment. 
A strap means is secured by its ends to the sides of the compartment for 
securing the compartment to the waist of the person using it. A plurality 
of baffles extend from the front interior of the compartment to the 
rearward portion thereof to prevent the compartment from becoming 
substantially distorted when the person using the device rests his or her 
head on the top portion thereof. 
The method of this invention comprises placing an inflated substantially 
rectangular flexible compartment on the lap of a sitting person, causing 
the person to lean forward to rest the person's head and arms on the top 
of the compartment to bind the compartment between the head and arms, and 
the lap of the person, and to provide resting support for the person's 
head and arms.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
The rest pillow 10 comprises an inflatable compartment 12 having a top 14, 
a bottom 16, front portion 18, rear portion 20, and side portions 22. The 
compartment is substantially rectangular in shape. An inflation port or 
valve 24 is located in the top 14 of the compartment. The compartment 
normally can be inflated by the person using the device who can blow air 
into the compartment through valve 24 in the same way that a balloon would 
be inflated. 
Three baffle sheets 26 having forward ends 28, and rearward ends 30, with 
side edges 32 extend between the front portion 18 and the rear portion 20 
of compartment 12. The baffle sheets are located within the interior of 
the compartment and are secured by their forward and rearward ends 28 
which are secured in any convenient fashion to the interior surfaces of 
the front portion 18 and rear portion 20, respectively, of the compartment 
12. The side edges 32 of the baffle sheets are not secured to the interior 
sides 22 of the compartment so that when the device is inflated and 
deflated, air may move past the baffle sheets and between the edges 32 and 
the interior surface of compartment sides 22. 
A length-adjustable strap 34 having ends 36 is secured in any convenient 
fashion to the center portions of sides 22 of compartment 12. When in use, 
the strap 34 is extended around the waist of the person using the device 
as will be described hereafter. 
With reference to FIG. 1, a vehicle seat 38 supports a person 40 who is 
sitting in the seat. The numerals 42, 44, 46 and 48 designate the head, 
arms, lap and waist, respectively, of the person utilizing the rest pillow 
10. The numeral 50 (FIG. 5) designates a horizontal plane passing through 
the underarms of the user. The forward upper edge 52 (FIGS. 1 and 5) 
defining the intersection between top portion 14 and front portion 18 
dwells generally in plane 50. The vertical height of pillow 10 (FIGS. 1 
and 5) spans the distance between the person's lap 54 and plane 50, and is 
determined by the degree of inflation of the pillow. The pillow is 
preferably so inflated so that the person on whose lap the pillow is 
resting can lean forwardly to rest the head (and arms if desired) on the 
top 14 of the compartment substantially at the level of plane 50. The top 
14 has no preformed indentations for the arms or head of the user (FIG. 
2). The top 14 may not be completely planer at all conditions of inflation 
for all sizes of persons. Nevertheless, it is preferred that the ultimate 
support height of the positions of top 14 upon which the head is resting 
be at the highest point of top 14 at the level of plane 50. 
The compartment 12 is comprised of a flexible plastic material as are 
baffle sheets 26. This permits the compartment, when deflated, to be 
folded into a compact size for storage or transportation. 
To use the rest pillow 10, the compartment is unfolded from its storage 
condition, and the user merely opens the valve 24 and blows air within the 
compartment to inflate it to the position shown in the drawings. The air 
pressure within the compartment should normally not exceed the ambient air 
pressure surrounding the compartment so that the compartment will be 
pliable and flexible for added comfort to the user. 
The person using the rest pillow will place the pillow on his or her lap. 
The vertical height of the pillow preferably should span the vertical 
distance between the person's lap 54 and a horizontal plane 50 passing 
through the underarms of the user. If desired, the strap 34 can be 
extended around the waist of the person in a taut condition so to further 
insure the stability of the compartment on the lap. 
The person using the device can then lean forward as shown in FIG. 1 so 
that the head and/or arms are substantially supported on the top 14 of the 
compartment or plane 50. The weight of the person's head and/or arms tends 
to bind the inflated compartment 12 between the person's head and lap. 
The depth of the compartment 12 measured between the front portion 18 and 
the rear portion 20 normally should be no greater than the breadth of the 
person's lap. 
As is clear from the forgoing description, the rest pillow will easily 
enable the person using it to rest or sleep while in a sitting position. 
The comfort of the rest pillow will facilitate resting or sleeping. 
When it is desired to store the rest pillow after being so used, the port 
24 is opened so that the air within the compartment can escape. The belt 
34 is detached from the waist of the user, and the device is folded into a 
compact condition. 
From the foregoing, it is seen that this device and method will achieve at 
least all of its stated objectives.
