CHAIR SYSTEMS AND METHOD
BACKGROUND OF THE INVENTION
[0001] The following includes information that may be useful in
understanding the
present disclosure. It is not an admission that any of the information
provided herein is prior
art nor material to the presently described or claimed inventions, nor that
any publication or
document that is specifically or implicitly referenced is prior art.
1. FIELD OF THE INVENTION
[0002] The present invention relates generally to the field of chairs and
more specifically
relates to a portable chair system.
2. DESCRIPTION OF RELATED ART
[0003] Travelling has become a very common part of life, whether it is for
work, visiting
friends or family or for a vacation. People often travel for long periods
during which time
they are seated in a chair and are generally sedentary. In particular,
traveling on airplanes
requires a passenger to be seated in a cramped position for many hours.
Travelling in trains,
buses and the like can also see a passenger seated for long periods of time in
awkward and
uncomfortable positions. A suitable solution is desired.
[0004] U.S. Pat. No. 7,954,900 to Totada R. Shantha et al. relates to a leg
supporting
device for use behind a head rest for air and vehicular travel. The described
leg supporting
device for use behind a head rest for air and vehicular travel includes a leg
supporting device
for use behind a head rest for air and vehicular travel having a head rest
support portion that

fits over a head rest of a forwardly positioned seat and supports a back flap
portion that hangs
down behind the forwardly positioned seat. A pair of adjustment straps
adjustably attach to
the back flap portion and supports a foot support portion. A user slips one or
both of their feet
into the foot support portion and then adjusts the adjustment straps to
support their feet at a
desired height and position. The foot support portion handles to carry it. In
use, the leg
supporting device can be folded and placed within the foot support portion and
carried using
the handles until needed. One embodiment includes pockets for holding drinks,
computer,
