Two oral inflator valve assemblies are attached to the inflatable cell. Each oral inflator valve
assembly consists of an oral inflation valve mounted in an oral inflation tube, which in turn is
RF bonded to the inflatable cell. Both oral inflators are secured against the cell with a Velcro™
retaining strap. Each oral inflator accesses a separate chamber.
The oral inflator located on the front left lobe of the inflatable cell inflates/deflates the front
chamber. This inflator is used in the event that the rear inflatable chamber becomes damaged
or if the other chamber fails to inflate. When the inflatable cell is stored (packed), this inflator
valve is locked in the open position for use as back-up in an emergency.
The oral inflator located on the rear right lobe of the inflatable cell inflates/deflates the rear
inflatable chamber. This inflator provides an alternate means of inflation in the unlikely event
that the manual or automatic inflation device malfunctions. When the inflatable cell is stored
(packed), this inflator valve is locked in the closed position to prevent venting during inflation.
Both inflators also provide a means of "topping up" the cell to compensate for normal leakage
or under-inflation due to excessively cold temperatures. As well, these oral inflators provide a
means for cell deflation.
2.8 PROTECTIVE CONTAINER
The protective container is constructed of flame retardant aramid Nomex
®
cloth, sage green in
color. It is attached directly to the survival vest with a speed lacing loop system. The container
houses the inflatable cell, providing a compact, flame resistant protective enclosure.
The un-inflated cell is attached directly to the inside of the protective container with a speed
lacing loop system. The cell is neatly folded and packed within the container, which in turn is
secured in the closed position with a system of slide fasteners, and a Velcro™ tab. The tail
ends of the slide fastener tapes are protected by 'tucking' the tails into the lower openings of
the secured container to prevent premature opening.
The container’s slide fastener closure is closed with separate sliders, which are stowed and
secured with a lanyard inside the pockets located on the inside of the survival vest.
The inflation handle lanyard passes through the upper reinforced opening at the rear left of the
container and Velcro™ attaches the beaded inflation handle to the underside of the protective
container. The anchor straps for the lobes of the inflatable cell pass through the lower
reinforced openings in the protective container.
Inflation of the life preserver, forces the fasteners around the periphery of the container to
separate, allowing the cell to reach its fully inflated shape.
