Claims  |
|
|
What is claimed is:
1. An inflatable pillow adapted to be connected to a seat comprising
relatively large inflatable end sections and an intermediate section that
is generally trapezoidal in shape with a larger upper portion and a
smaller lower portion to accommodate free movement of the user's head
portion, which intermediate section is inflatable to a fraction of the
size of the end sections and adapted to receive a resting head between
said end sections, valve means secured to said pillow to control the air
flow to said pillow, the intermediate section defining passage means
interconnecting said end sections to permit simultaneous enlargement of
said end sections when air is introduced into said pillow through said
valve means, and adjustable strap means connected to said pillow for
securing the pillow to a seat to support the pillow in place while being
used.
2. A pillow as set forth in claim 1 in which the end sections are also
generally trapezoidal which has an upper portion that is smaller than its
lower portion whereby the pillow is generally rectangular in shape. |

FIELD OF THE INVENTION
This invention relates to an inflatable pillow that can be readily secured
to a back support to provide a cushion for a user's head regardless of its
resting position.
BACKGROUND OF THE INVENTION
The present invention relates to an inflatable pillow which in its
non-inflatable stage is a very compact item that can be readily stored in
a small area when not in use. There have been inflatable pillows used
prior to applicant's novel invention, but these pillows were not capable
of providing a fixed cushioned support regardless of the position of the
head of the user resting on the pillow. Prior pillows of this type in
addition to not providing a high degree of comfort for the user's head and
neck were not adapted to be connected to a support such as a back rest
which avoids the common problem of the pillow being displaced during
usage, thus resulting in discomfort to the user resulting from such
dislocation. Previously used pillows also did not provide for a continuous
fixed cushioned support for the user's neck portion as well as the head
resting portion when the head of the user moves from side to side. The
lack of firm positioning of the pillow during usage and the particular
cushioning features necessary to provide complete comfort during use
presented disadvantages which are overcome by the present invention.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a pillow that
provides an extremely comfortable head and neck rest for the users
regardless of the position in which the users find themselves during their
resting mode. The novel pillow provides full support for the user whether
the head is located in a frontal or in a side position. The cradle support
of the pillow permits free movement by the user but continues to provide a
complete cushion support when the user moves from side to side during
resting. To more fully accommodate the user, the end portions of the
pillow are inflated to several times that of the intermediate portion,
with the result that the head is firmly supported in a fixed cradled
position while resting on cushioned inflatable end and intermediate
sections.
In a preferred embodiment, the end sections of the pillow that are
approximately 4".times.8" are inflated to approximately a three inch
thickness and the intermediate section is inflated to approximately one
and one-quarter inches. The overall shape is essentially rectangular
having a width of approximately 15 inches and a height of about 8 inches.
These dimensions are merely exemplary and they can be varied as desired.
The intermediate portion is tapered to provide better support and is
generally trapezoidal in shape with the longer portion of approximately 8
inches in width being located at its upper section and tapered toward the
lower section which is approximately six inches in width. The inflatable
intermediate section provides a cushioned support for the neck while
permitting a full range of head movement.
As aforementioned, when not in use, the pillow takes a flat, generally
rectangular shape and thus can be stored in a very small space making it
very adaptable to carry for subsequent airplane, car or bus trips.
In one of the end sections, there is provided a simple flap valve mechanism
that includes a tubular portion and a valve closure secured thereto for
controlling the flow of air into and out of the pillow. The end sections
are interconnected by passageways formed in the intermediate section, with
the result that the end sections as well as the intermediate sections are
immediately inflated when air is introduced into the pillow. After being
inflated to the prescribed amount the valve is closed off to prevent air
from escaping. Thus, it can be seen inflation and deflation is quick and
easy.
The back portion of the intermediate section provides loops through which
extends a strap incorporating an adjustable buckle arrangement that
permits the pillow to be readily connected to most any size seat support.
When the pillow is to be affixed to a seat, the strap is merely wrapped
around the upper portion of the seat and tightened to retain the pillow in
position. When the pillow is no longer to be used the valve is opened with
the air escaping and the pillow compressed into a small area and stored.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of an inflatable pillow assemblage mounted on
a seat back;
FIG. 2 is a front view of the pillow; and
FIG. 3 is a rear view of the pillow, partially broken away to show the
buckle arrangement and the strap connection to the pillow.
DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to FIG. 1, there is shown a pillow 10 including inflatable end
sections 12, 14 and an intermediate section 16 strapped to the back of
seat 17. To inflate the pillow, a valve 18 including a tubular portion 20
and a sealing cap 22 connected to the tubular portion 20 is located in the
lower right-hand corner of the front of the pillow (see FIG. 2). The
inflatable sections 12 and 14 are connected by a passageway 24 so that
both end sections 12, 14 are immediately inflated when air is introduced
through the tube 20. It is noted that there are sealed portions 30 located
around the perimeter of the pillow as well as intermediate sealed portions
32 that function to control the air flow within the pillow and define the
various inflated and deflated areas.
As seen in FIG. 1, several of the sealed portions 32 define transversely
extending spaced inflatable sections 33 that provide support for the
user's neck when the pillow is in use. The upper portion of the
intermediate section 16 includes a generally flat portion 34 which is
defined by a generally rectangular seal 32. Located intermediate the
section 34 is a smaller rectangularly sealed area 35.
The pillow 10 is connected to the seat back 17 by a strap 40 which extends
through loops 42 formed in the panel section 34. The strap 42 is connected
by a buckle 44 and the length of the strap can be varied by changing the
overlapped portions of the strap through the buckle 46.
Thus, when the pillow is to be used it is inflated by introducing air
through the tube 20 to the inflated condition shown in FIG. 1 and then
wrapping the strap 40 around the seat back 27 to locate it in position.
It is intended to cover by the appended claims all such modifications and
embodiments that fall within the scope thereof.
