NETTI DYNAMIC FREE MOVEMENT BACK
SUPPORT CYLINDER – ACTIVATED
The dynamic back solution of Netti Dynamic System
is activated by pulling the recline handle.
See page 34 for detailed illustrations.
The back support cylinder can be considered
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. In chapter
6.20 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.

ASSESSMENT AND CHOICE OF
NETTI DYNAMIC BACK SUPPORT
GAS CYLINDER
The chair back position is defined by the chair
back cylinder.
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.
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 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 damage on the
leg support.
Warning: the leg support might break if it is
not correct adjusted; meaning that the user
leg extension reaches the end of the leg
support dynamic area, or if the user has slid
forward.
