and front forks.
•
To change the height of the front castors - loosen the
wheel from the front fork and replace its axle in the
required position.

Always check and adjust the angle of the front fork

5.4.4 NETTI SEAT PLATE
The Netti Seat plate is an advanced seating platform
developed to give persons sitting long time, improved
comfort and reduction of seating problems.
•
The lowered surface under the sitting bone area allows
for reduced pressure under the sitting bones.
•
The sloping edge from the lower to higher seat plate area
provides a sliding limiter for the sitting bone, reducing
sliding.
•
The possibility for seat plate depth adjustment allows for
correct positioning of the pressure releasing lowered area
and ensures good support under the thighs.
•
The perforated surface allows for ventilation - reduced
moisture.
•
The dynamic solution allows for the seat plate to swing
up following the hip movement by body extension.
SEAT DEPTH ADJUSTMENTS
The seat depth can be adjusted in several positions and
in 3 different places:
• at the rear, by moving the chair back hinge - 2 positions.
•
at the middle of the seat plate - by pulling out the rear
part of the chair plate, extending the seat plate itself.
•
at the front by changing the position of the seat plate in
the seat frame.
In addition the leg support extension pieces can be
moved forward protruding at the front of the seat plate.
Adjustments are done to give the user a comfortable seating
position with proper lumbar support while the knee joint is
aligned with the leg support knee joint and to ensure that
the sitting bones are correctly placed on the seat plate.
By adjusting the seat depth, the chair balance and the
driving characteristics may change. A well balanced chair is
easy to drive without easily tipping backwards.
Please make a careful assessment
of how the seat depth adjustments
most favourable shall be made to
keep good balance in the wheelchair.
When seat depth adjustment is
required, the position of the seat plate
must also be adjusted to ensure good
lumbar support and still keep align-
ment of the leg support knee joint to
the user knee joint.
The seat plate depth is delivered as a
standard following the seat width as
shown in the table.
