Backrest Panels are designed with pre-drilled holes to enable
Lateral Supports to be fitted at various heights, Fig.20.
When factory fitted, the Supports will be positioned as requested on the
original prescription. However, these positions may need to change due to
user growth, positioning needs or changes required in seasonal clothing.
Swing-away and Wrap-around styles, feature a positive locking method in
the forward position, which is released by depressing a Lock-Release button
on each device, Figs.21 & 22.
The curved Wrap-around style lateral pads are produced with tension
straps, connected and adjustable via a buckle.
To raise or lower the Lateral Support Mountings, it will be necessary to remove
both securing screws from each Mounting, these are located at the rear of the
Backrest Panel, Fig.20. Reposition the Mountings using the alternative fixing
points provided and using the original screws and special key-way nuts.
NOTE:
When tightening the securing screws, care should be taken to ensure the
key-way nuts are located correctly in the Mounting Bracket slots.
Fully tighten the securing screws
Width adjustment of the Lateral Supports with the user seated can easily be
carried out, by slackening the retaining screws, adjust as required and retighten
screws just sufficient to prevent any movement.

BACKREST INSTALLATION
(Standard Backrest)
The Standard

from the Positive Locking model, by
virtue of the shaped tongue on the
lower edge Fig.5, which is designed to
engage with the slot located at the rear of
the Seat Panel Fig.4.
Therefore, installation of the Backrest
Support Brackets and Upper Mounting Lock
- Pin Brackets, is the same as detailed on
the previous page and above covering the
Positive Locking model, also shown in
Fig.13.
