Low shearing at the back
The
LEVO
combi
is equipped with a new low shearing
mechanism (see picture 13) which eliminates the shearing
movements for most comfort as a user benefit in a sitting as
well as standing position. This shearing mechanism
counteracts to the shifting of the wheelchairs back towards
the upper body of the user. These shifting movements were
often considered as uncomfortable. Thanks to the low
shearing mechanism the
LEVO
combi
feels like tailor made
in each position. The most comfortable stand-up motion is
also realized by the fact that the distance between the
armrest and shoulders stays constantly the same.
The new unique low shearing mechanism is adjustable to the individual body
measurements using correlatively one of the three different positions to mount the
connecting piece (A).
As a standard the connecting piece is fixed to middle drill hole; this means the medium
adjustment and the compensation of 9 cm / 3.5”. Fixing the connecting piece on one of
the other holes the compensation will be of 8 cm / 3”, respectively 10 cm / 4”. Please
read the service instructions for more information about this subject. (Service
instruction section 8.7.)

Backrest assembly of the LEVO
combi
standard
backrest
The standard backrest consists of a fabric covering. Around the backrest tubes are four
strong broad straps with stitched on Velcro fastener mounted. The straps are hidden
under a cover which is fixed with a Velcro fastener to the seat plate. The cover is lightly
cushioned and is positioned over the front of the backrest. The back part is covered by
a strong fabric.
Adjustment of the backrest: The standard backrest can be individually adjusted.
Remove the back cover from the backrest to get access to the straps.
Span each of the four straps individually according the needs of the user to optimize
the support in the sitting position.
Put the back cover back in place.
The LEVO combi comes with the option 90° back angle directly linked with 90° leg
rest angle adjustment. In this case you must choose a suitable and stable backrest
system to be mounted. Again, this must be mounted in such a stable way, that it
cannot be moved or pivoted through weight or balance point shifting in any position
by its self.

V-Trak backrest system (option)
The
LEVO
combi
can be supplied optionally with the V-Trak backrest system, which
guarantees most comfortable sitting. The V-Trak system provides features for most
individual adjustment. The backrest consists of a comfortable padded adjustable back
shell and a fully adjustable mounting system. A backrest of 63 cm / 25 inches length is
known as a V-Trak standard. Further options are available such as a head support
for example.
