leg support and also easy handling of the leg
support for user and attendants.

horizontal angle.
• Scales on several adjustment features make it easy

The seat depth can be adjusted in several
locations and directions:
The chair-back hinge can be repositioned to
adjust seat depth backwards.
Extension pieces allow for increasing the seat
depth in the front.
Consider the wheelchair balance. See further
information to seat depth adjustment on the
next page and in wheelchair user manuals.
2. ADJUSTING THE
NETTI GRANDIS
LEG SUPPORT
TO THE USER
To achieve the best support and also the most easy
handling it is vital to do the proper and accurate rst
time seating adjustments.
INITIAL ADJUSTMENTS
Start with normal relaxed seating position.
The aim is to have the centre of the users knee joint
aligned with the centre of the leg support knee
rotation centre – while the user at the same time is
having good back support of his lower back – even
when the leg support angle is changed.
With this in mind start with:
SEAT DEPTH ADJUSTMENTS =
BALANCING THE CHAIR
It is vital to adjust the seat depth correct.
Adjustments to the seat depth change the
centre of gravity which eects the balance of
the wheelchair. Centre of gravity too far back
= the wheelchair tips easily backwards.
Centre of gravity too much forwards brings
too much weight to the front castors and it is
very heavy to drive and steer the wheelchair.
Proper adjusted seat provide stability and
good manoeuvrability of the wheelchair.
Correct seat depth:
Loosen the Velcro straps of the back support.
Check that the user is getting into the chair
rmly. Adjust the back support by pulling
the straps of the Velcro. The knees of the
user should align with the joint of the leg
support both in height and in depth –
with 2 nger widths distance between seat
of the users leg.

SEAT DEPTH ADJUSTMENTS
IN THE BACK:
By moving the back brackets followed by adjusting
the back cylinder head. When the chair is equipped
with a main wheel larger than 16” remove the main
wheels rst.
Back hinge adjustment:
• Remove the screws on each side which are holding
the back hinge.
• Pull the bracket on each side back or push it
forward to desired position before the screws are
xed again.
Recline cylinder head position:
• Remove the QR bolt holding the recline cylinder
head.
• Reposition it in the corresponding number hole as
the previously adjusted chair back bracket.
• This will also have inuence on the chair back
angle.
By choosing another hole you can change the angle
of the back support which means that the back angle
or hip angle will be more open or more closed.
SEAT DEPTH ADJUSTMENTS
IN THE FRONT:
are done by adjusting the extension pieces where the
leg supports are mounted. The extension pieces are
adjusted by removing the screws holding them and
pulling the extension pieces out to desired position.
The aim is to have the centre of the users
knee joint aligned with the center of the
leg support rotation centre – while the
user at the same time is having good
back support of his lower back –
also when the leg support angle is
changed.
Always do seat depth adjustment
both in front and back to balance the
chair.
