statistically sampled for manufacturing purposes.
[0009] Similarly, yet still another feature of the present
disclosure is wherein the optimized dimension set is customized to
a particular user, by adjusting from a predetermined set of values
based upon statistical or sampled data using software.

comprising, in combination, a sling-seat assembly integrated with a
support apparatus for a bottom cushion, which cushion is disposed
about a planar axis which defines a chevron-like pattern in the
shape of a ray originating at a back portion of the bottom cushion
where it joins with a back upper portion of the seating
apparatus.
[0011] According to yet a still further feature there is provided a
sling-seat element for supporting the ischial tuberosities of a
user, which comprises, in combination; a first elongated lower
extension member, defined by an acute angle extending between it
and a second elongated lower extension member, forming a
chevron-like shape, an upper extension member emerging from the

BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The present invention will be more clearly understood by
reference to this specification in view of the accompanying
drawings, in which:
[0013] FIG. 1 is a schematic of a prior art seating construction in
cross-section;
[0014] FIG. 2 is an embodiment of an enhanced fundiform seating
product according to embodiment of the present disclosure;
[0015] FIG. 3 is a detailed aspect of an exploded view according to
teachings of embodiments of the present disclosure;
[0016] FIG. 4 shows detailed aspects of the sling-seat element, as
shown in FIG. 2 and FIG. 3.
DETAILED DESCRIPTION
[0017] The present inventor offers for consideration an effort to
mitigate a leading global symptom or disability driving disease
state--back pain. This is a long-term set of issues that most
developed and developing countries have been compelled to deal with
as individuals are incented to move from upright posture to a
work-based sitting rhoutine , for at least part--if not most--of
their working days.
[0018] For example, 80 percent of adults in the United Kingdom
spend greater than 350 hours per year in cars and one-third
diagnosed with back pain have attributed sitting in cars or at work
as a cause of their malaise.
[0019] For the United Kingdom, this contributes to massive totals
of compromised man-hours, in the case the example itself
ostensively amounts to an excess of 5 billion of work lost, in
pounds sterling.
[0020] Fortunately, a mitigating process-set and various different
types of apparatus are available from Nubax Limited
(www.Nubax.co.uk and www.Nubax.com) the ProBax.TM. seating
technology provides a combination of features ranging from
significant improvements to comfort level, to increased blood flow
through the body, resulting in improved alertness and performance.
Likewise, according to the teachings of the present invention a
user experiences an enhanced driving position allowing drivers to
maintain a correct natural curvature of the spinal process for
longer which maintains a head position closer to the normal
positioning of a conventional head restraint. The resulting
improved spatial awareness allows user to perceive improved vehicle
handling, among other things.
[0021] The ProBaX.TM. brand of seating technology has been
incorporated into leading lines of cars, including the 2006 Lotus
MV Elise.RTM. and Exige.RTM. models. Marked postural position
improvements in occupants of the ProBaX.TM. brand of seating
technology have been noted. Medical professionals have validated
both the spinal maintenance aspects and the increased blood full
obtained with the teachings of the present disclosure.
[0022] Likewise, among those skilled in the aviation fields, the
benefits of reduced muscle fatigue have ostensively resulted in a
high degree of demand for the objects of the instant teachings.
This is particularly interesting in that the instant system has
been extensively tested with people of various shapes or sizes, and
provided substantial relief to them.
[0023] Turning now to FIG. 1 an example of the prior art seating is
shown. Those in the industry have pointed out a strong need for
cockpit space and economic efficiencies with involved materials.
Conventional seat 101 is shown in this view of the prior art.
[0024] During the 1950's faced with analogous seating challenges,
the United States Air Force concluded that correct seating posture,
unlike that illustrated in FIG. 1 would have a strong likelihood of
improving alertness, based upon the improved blood flow.
[0025] A user seated in the prior art seat 101 of FIG. 1 slumps
into an uncomfortable posture and the user's head has nothing to
prevent, inhibit or otherwise back and forth improvement, in
attempts to achieve a helpful seating position. The same is true of
user's body, which is pushed into abutting contact with upper
portion 103 of conventional seat 101, or even worse, uncomfortably
shifted into a challenged posture wedged between lower portion of
conventional seat 105 and upper portion 103.
[0026] Referring now to FIG. 2, the ProBax.TM. brand of seating
technology is manifested in the schematic and exemplary seat 102,
which illustrates the working of the processes and products of the
present disclosure. It is noted that any user disposed upon seat
102 has a different set of angles relative to both the back
support/upper portion of seat 107 and lower portion of seat 104.
This is due to the unique configuration of the instant disclosure
and to the fact that the less foam and no pre-existing lumbar
mechanism work to make the user dis-aligned as in FIG. 1.
[0027] Extensive work has been done relative to trials on the blood
flow or drivers in the seat of FIG. 2 versus the conventional
seating designs shown in FIG. 1. Conclusions by medical and
cadiovascular thought leaders consistently pointed to a
singnificant imporvement in lowert limb blood flow for the
occupants of seats embodying the teachings of the present
disclosure.
[0028] What has been established is that by creating a zone 109 for
landing the ischial tuberosities 109 increased blood flow results
and response times are enhanced, alertness levels raised and marked
reductions in levels of muscle fatigue noted. There is likewise a
substantial reduction in deep vein thrombosis-like events.
[0029] The blood testing regimen was conducted by application of
Bernouilli's Equation to specific measurements of blood pressure
and velocity through the femoral vein in the leg, enabling a
calculation of an individual's blood flow form one seat to another.
Measurements using the seat of FIG. 2, as embodied for examples in
prototypes of the 2006 Lotus brand of MV Elise.RTM. automobiles
demonstrated an imporvement of up to thirty percent over the seats
shown in FIG. 1.
[0030] Referring also to FIG. 3 and to FIG. 4, embodiments of the
present disclosure are shown as incorporated into seats for
automobiles and airplanes. As a user is situated on lower portion
of seat 104, the location of the extension members 115 and 117 will
urge a user's ischial tuberosities to be aligned, when combined
with upper extension member 113, such that a desired lordotic
posture (see FIG. 2) is maintained. This allows a user's upper
torso and neck to be positioned in a better alignment realtive to
the back support/upper portion of the seat 107, an once aligned on
lower portion 104, by way of extension members 115 and 117, it
feels more comfortable and maintains better posture while engaged
in dynmaic activity, such a driving a racing car, or flying in a
plane.
[0031] FIG. 4 shows a detailed view of the fundiform/sling element
111, which is dimensionally varied relative to the weight of a user
to achieve optimal landing of the ischial tuberosities of the user.
Referring also to the illustrative schematic of FIG. 2, one can
view a typical user sitting on fundiform/sling element 111 having
an overall length of at least about 950 millimeters (mm), with a
width of at least about 75 mm and a widest point of approximately
295 mm. For an average user this means that at least about 370 mm
is an extension length for upper extension portion 113.
[0032] Angle theta is at least about 20 degrees, or from 21 to 25
degrees in an average seat, and may vary from approximately one to
thirty degrees based upon variations in weight and size of the
user.
[0033] Likewise, the extension members 115 and 117 (or chevrons)
are typically three to four inches in width (at least about 1
inches to 30 being possible) and the depth of these elements of
between 1/4 of an inch and 10 inches, with 3/4 of an inch to 1 inch
being average.
[0034] While the present invention has been illustrated and
described by means of a specific embodiment, it is to be understood
that numerous changes and modifications can be made therein without
departing from the scope of the invention as defined in the
accompanying claims.
