Advanced technology anti-G suit

DETAILED DESCRIPTION Referring now to FIG.
1 of the drawings, there is shown a simplified perspective view of an anti-G suit pressure bladder 10 made according to the teachings of the present invention showing pressure bladder 10 without its outer covering.
Pressure bladder 10 is in three primary sections, an abdominal bladder section 12 and two mirror-image wraparound leg bladder sections 14.
An inflation or fill hose 16 is integrated into pressure bladder 10.
Fill hose 16 preferably includes a wire coil or coils along its length to prevent kinking or occlusion of the hose.
Pressure bladder 10 is made of polyurethane impregnated nylon or other impermeable or pressure containing materials.
Pressure bladder 10 is constructed by sealing together precut pieces of bladder material.
Sealing techniques may include radio-frequency (rf), ultrasonic, tape and glue, or a combination of these methods.
In use, abdominal bladder section 12 covers the abdominal area of an aircrew member leaving uncovered the buttocks.
Each leg bladder section 14 wraps around a leg of an aircrew member so that edges 18 and 20 overlap slightly.
Pressure bladder 10 is shaped so that the crotch area is uncovered.
FIG.
4 shows the slightly overlapping edges 18 and 20 when a leg bladder section 14 is wrapped around a leg of an aircrew member.
Pressure bladder 10 includes pouch areas 22 at the knee region of each leg bladder section 14.
Pouch areas 22 are made by sealing two vertical seams and one horizontal seam at each knee to pull the bladder material into a pouch-like shape at that point.
Pouch areas allow leg bladder sections 14 to bend at the knees.
Pressure bladder 10 also includes a pair of interior channels 24 connecting abdominal bladder section 12 and leg bladder sections 14.
Each channel 24 is filled with TRILOCK.
RTM.
, a noncompressible material available from a variety of sources that allows the free flow of air.
Channels 24 help preserve the free flow of pressurized air through pressure bladder 10 when an aircrew member is in a sitting position which would otherwise tend to make a constriction at the bend between abdominal bladder section 12 and leg bladder sections 14
