SEAT BASE INSTALLATION
(Fixed/Bolt-on Interface method)
As positioning and methods of attachment for a fixed seat base may vary
according to the make and model of intended surrogate wheelchair, the
information detailed below should be used as general guidelines only.
Therefore, the
caddy
Seating System should only be installed by a suitably
qualified person.
Hexagon Keys 4 & 5mm, 10mm Spanner/Socket.
Power Drill with drill bit to suit the diameter of the mounting screws supplied
with seat unit.
Where a fixed Seat Board is already in place on the wheelchair, it is
suggested that this be removed and used as a template for drilling the
caddy
Seat Base Board. As the O/E Seat Board may be secured to the
wheelchair seat frame by either four or six screws it is recommended that
the
caddy
Seat Board be secured by the same number of screws.
Disconnect and remove any original seating upholstery from the surrogate
wheelbase (methods may vary according to make and model).
Initially it is recommended, that the
caddy
Seat Unit be temporarily placed on
the surrogate wheelchair for the installer to gain a better understanding of
where the
caddy
should best be finally positioned.
Disconnect and remove the O/E Seat Board and place this over the
caddy
Seat Base Board to mark the drilling positions for attaching to the wheelchair
frame. (Temporary removal of the individual Seat Depth Adjustment Panels may
be necessary prior to drilling)
Drill the appropriate number of holes required through the
caddy
Seat Base
Board, then replace the Seat Base Board onto the wheelchair to confirm correct
drilling alignment with the wheelchair frame.

Accessory ADJUSTABLE PELVIC SUPPORTS
and
KNEE ADDUCTORS
INSTALLATION and ADJUSTMENT
Whilst supplied with “Fixed” Straight style Pelvic Supports as standard,
alternative mounting brackets are also available (see the
caddy
prescription
form QMF100) for details and can be mounted to the Seat Panel as per the
“Fixed” style. These will enable each Support to be positioned inboard by
2.5cm or 5cm. Alternative brackets are available from RMS Sales.
When replacing Pelvic Support brackets on Seat Units with sufficient clearance
under the seat, the mounting screws can be accessed from the underside by
tilting or raising the Seat Base.
NOTE:
The brackets DO NOT have to
be removed where the Pads only, are
being replaced, as the Pad to bracket
retaining screws and nuts are easily
accessed with the Pad covers removed.
Remove both screws from each
mounting bracket and retain the
threaded Lock Plates.
The new brackets can be attached to
the upper surface of the Seat Base by
inserting the screws from the underside
of the Seat and screwing into the
threaded Lock Plates as Fig.27.
Where Knee Adductors are being installed for the first time, the method of
attachment may vary according to the amount of underside access available
to the Seat Base. For normal installation, i.e. Good access, the retaining
screws should be installed from the underside and screwed into the threaded
Lock- Plates supplied, ensuring the key ways locate correctly into the slots in
the brackets before fully tightening.
Alternatively, where only limited access is available, the bracket retaining
screws may be installed through the slots in the brackets, downwards into the
threaded Lock Plates on the underside of the Seat Panel.
The Pads can be attached to the new brackets using the screws supplied and set
to the required position before fully tightening.
Adjustment of the bracket positions can be made both forwards and backwards
as well as laterally, just by slackening the retaining screws and moving to the
required position via the slots provided in the Seat Base and the Pad mounting
brackets. Retighten all screws sufficient to prevent any movement.
IMPORTANT NOTE: Users of Supportive Seating and associated devices,
should be regularly checked in areas of contact, for redness of skin, abrasions
and pressure sores etc.
