NETTI DYNAMIC FREE MOVEMENT BACK
SUPPORT CYLINDER – ACTIVATED
The dynamic back solution of Netti Dynamic System
is activated by pulling the recline handle.
The back support cylinder should be assessed.
It can be replaced by another cylinder (more /
less Newton) if needed; either because of new or
changed user needs, or if the weight of the user has
changed.
Please contact your local dealer for advice on which
new cylinder to choose. At the end of this manual
the change of gas cylinder is described.
ASSESSMENT OF DYNAMIC BACK SUPPORT GAS
CYLINDER FORCES, SUITING USER STRENGTH
AND MOVEMENT PATTERNS
An assessment of the user is needed to find the right
power of the cylinder.
Correct solution:
The back cylinder gives full support on a full, open
kinetic chain movement during the user’s extension
pattern. When the user starts to relax, the cylinder
move the back support to its original position.
OPTION 2:
NETTI DYNAMIC FREE MOVEMENT
BACK SUPPORT CYLINDER
allows the back support
to move backwards to full recline, giving full support
during extension movement. When the user starts
to relax the cylinder move the back support to its
original position.
The strength of the full free cylinder has to
be fitted individually according to body
weight. A cylinder that is too strong will not
allow the back support to move. A cylinder
that is too weak will not be strong enough to
lift the back support to its original position.
Standard cylinder forces are: 600, 800, 1000
and 1200 N.
NETTI DYNAMIC FREE MOVEMENT BACK
SUPPORT CYLINDER – LOCKING
The free cylinder is lockable in any reclined angle
– when the recline handle on the back is in neutral
position. This may be necessary / required, when
the chair is used as seat in a car or driven on rough
ground where a sudden spastic extension may make
the chair unstable. Or when the user needs to lay
back for a rest.
If you recline the chair back on a wheelchair
with free cylinder, locking it in reclined
position, it is only the Netti Dynamic Leg
supports, seat plate and head support that
will respond to spastic movements.
If you lock the free cylinder, it is important
that the user is correct positioned and not
sliding forward, to prevent skin damage and
damage on the leg support.
