reclining
back is

located

frame.
To
ad¬
just
the
seat
back,

position
the
seat

INTEGRATED
SEAT
BELT/SHOULDER
HARNESS
All
seat
positions
are
equipped
with
integrated
seat
belts/shoulder
harness
assemblies
(Refer
to
Figure
7-4).
The
design
incorporates
an
overhead
inertia reel
for
the shoulder
portion,
and
a
retractor
assembly
for
the
lap portion
of
the
belt.
This
design
allows
for
complete
freedom of
movement
of
the
upper
torso
area
while
providing
restraint
in
the
lap
belt
area.
In
the
event
of
a
sudden
deceleration,
reels
lock
up
to
provide positive
restraint
for
the
user.
In
the
front
seats,
the inertia
reels
are
located
on
the centerline
of
the
upper
cabin.
In
the
rear
seats,
the
inertia reels
are
located
outboard
of
each
passenger
in
the
upper
cabin.
To
use
the
integrated
seat
belt/shoulder
harness,
grasp
the
link
with
one
hand,
and,
in
a
single
motion,
extend
the
assembly
and
insert into the buckle.
Positive
locking
has
occurred
when
a|
distinctive
"snap"
sound is
heard.
Proper
locking
of
the
lap
belt
can
be
verified
by
ensuring
that
the
belts
are
allowed
to retract
into
the
retractors
and
the
lap
belt
is
snug
and low
on
the
waist
as
worn
normally during
flight.
No
more
than
one
additional
inch
of
belt should
be
able
to
be
pulled
out
of
the
retractor
once
the
lap
belt
is
in
place
on
the
occupant.
If
more
than
one
additional inch
of
belt
can
be
pulled
out
of
the
retractor,
the
occupant
is
too
small
for
the installed
restraint
system
and the
seat
should
not
be
occupied
until
the
occupant
is
properlyl
restrained.
Removal
is
accomplished
by
lifting
the
release mechanism
on
the buckle
or
by
pressing
the release
button
on
the buckle
and|
pulling
out
and
up
on
the
harness.
Spring
tension
on
the
inertia
reel
will
automatically
stow
the harness.
