2. Attach the wooden “yoke” to the back of the chair.
This can be placed on the “inside” or the “outside” of
the chair back depending on the depth of the seat
needed. Place the
(2
) hex bolts
through the pre-drilled
holes. Place a nylon washer between the wood and the
knob. Secure with small knobs.
Tighten securely
.
3. Attach the Insert to the chair.
A.
Place the lower carriage bolts through the slots in
the back of the chair. Place the upper carriage bolt
through the hole in the top of the yoke.
Note:
The
washer-nut / nut-washer combination should be on
the “inside” of the chair. Secure by placing the
“flower” knobs (see illustration) on the ends of the
carriage bolts.
Tighten all knobs securely.
B.
The Insert is adjusted vertically by loosening the 1
st
nut on the top bolt to allow the bolt to slide in the
insert slot. Loosening the lower pair of “flower”
knobs allows the bolts to slide in the chair slots.
Note: The insert should be positioned so that
the top of the “butterfly” straps are even with
the shoulders.
Re-tighten the nut and knobs
securely
once the appropriate height is obtained.
C.
The seat depth (of the Adjustable Positioning
Chair) can be reduced by up to 3” (with the 4”
bolts) or 5” (with the 6” bolts) by changing the
position of the 2
nd
nut in relation to the 1
st
nut.
Note:
The greater the distance between the two
(2)
nuts, the greater the seat depth reduction.
D.
When attaching the Winged Back Insert to the
Bolster chair use the 4” bolts and place the insert
close to the back of the chair.
4. The Butterfly Kit
comes attached but may need to be reconfigured for a custom fit. Place the top
strap through the one of the top two paired vertical slots, and the bottom strap through the bottom
two vertical slots in the insert.
Note: The insert should be positioned on the chair so that the top
of the butterfly straps are even with the shoulders and the buckle is below the collarbone.
Adjust the length of the top straps to position the chest piece at the desired location on the chest (see
below). Provide a “snug” fit by pulling on the lower set of straps only.
Care should be taken not to position the harness higher than the notch felt at the
top of the sternum (breast bone) as strangulation could occur.
