Trans Tibial Supports (Stump supports)
They attach and detach to the wheelchair in exactly the same way as
the standard footrests.
To raise or lower the support pad: -
Slacken the clamp screw and raise or lower the support pad to the
desired position. Tighten the clamp screw securely.
The use of the support may affect the stability of the
wheelchair.
8.4 Backrest options
Backrest extension
The extension is fitted onto bobbins that replace the existing
upper backrest retaining screws.
To fit the extension: -
Unscrew the bolts that secure the current backrest
canvas, replace these with the bobbins and screw in place. The
backrest extension contains two machined slots, for attachment
onto the two bobbins. See photo to the right. Place slots on
support tubes over the bobbins and push down firmly.
To remove the extension: -
Partially fold the wheelchair, lift the support tubes on the extension upwards
and remove from the backrest.
Tension adjustable backrest
The existing backrest can be replaced with a tension
adjustable backrest. The tension can be adjusted by
adjusting the length of the straps to increase or decrease the
amount of free play in the backrest. Release the free end of
the strap from the Velcro and pull back through the buckle to
increase the backrest free play or pull more of the strap
through the buckle. To tighten the strap and reduce the
backrest free play, ensure when adjusting that the straps are
fed back through the buckles and secure – attach free end to
Velcro. It is recommended that a comfort strut be used with a
tension adjustable backrest to maximise benefit.
