TRAVELER 4all Ergo & 4you Ergo usage instructions
20
Extreme settings such as drive wheels
mounted far to the front are only permitted for
experienced wheelchair users who are able
to actively shift their weight forwards during
operation.
To minimise the risk of tipping backwards,
we recommend using anti-tipping supports,
even with anti-tipping settings.
19 Back system
Avoid falling into the seating and backrest
upholstery/back shell as it significantly in-
creases the risk of an adjustment, falling down
or defects.
19.1 Backrest angle
19.1.1 Adjustment possibilities with an
adjustable backrest
If equipped with an adjustable and foldable
backrest, the backrest angle can be flexibly
adjusted without using tools and the backrest
can be completely folded away. The angle of
the backrest can be fixed in 7 positions in 5°
steps.
Observe that the centre of gravity is shift-
ed further to the rear by the enlargement of the
angle between the backrest and the seat sys-
tem and thus, the tipping point of the product is
reached much sooner.
19.1.2 Instructions for sitting posture with
an adjustable backrest
For a good sitting posture, we recommend
positioning the backrest vertical to the ground,
where possible.
With low backrests with adaptable belt cover
due to a disability, it may be advantageous to
slightly tilt the backrest forwards and to slacken
the top belt of the backrest upholstery so that
the slack in the upper area is greater in order
to achieve good sitting stability under certain
circumstances (see Chapter 19.2).
The adjustment possibility of the backrest an-
gle supports active sitting and ensures for flex-
ibility of the wheelchair user. An example in the
following:
if the angle of the seat has been changed
(see Chapter 18.2), the angle of the
backrest can be respectively readjusted.
When driving on slopes and when trans-
porting baggage (e.g. backpacks) on the
backrest, the centre of gravity shifts more
to the rear and the risk of tipping increas-
es. Then this can be counteracted by a re-
spective angle adjustment of the backrest
to the front.
For comfortable seating, the backrest can
be locked in a position to the rear so that
the backrest is tilted slightly back.
19.1.3 Adjusting the backrest angle or
folding down the backrest with an
adjustable backrest
To
adjust the backrest
, relieve it (otherwise
there is a risk of tipping) and then loosen the
locking pins that engage in the locking holes of
the side sections on the left and right. For this
purpose, grasp under the seat cover and in the
middle, pull the cord to the front that is linked
to the locking pin.
