17.4 Ergo Back backrest bar
The back system "Ergo Back backrest bracket"
normally consists of a backrest bracket (with or
without lumbar curvature) and an adjustable
backrest upholstery including customised back
padding. The adjustment possibilities of the
adjustable backrest upholstery
are de-
scribed in chapter 17.2.

ding removed (viewed from the rear)
If the Ergo Back backrest bracket is fitted with
a
back shell
instead of the adjustable backrest
upholstery, the adjustment possibilities de-
scribed in chapter 17.3 apply.

18 Seat 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.
The seat system usually consists of either
sprung Body Contour seat cover or a belt sys-
tem.
With a seating system from
Body Contour
seat cover
, there is no adjustment option. The
Body Contour seat cover has a springing effect
and when seating, automatically forms a slack.
Figure 29: Body Contour seat cover
The
belt system
can be subsequently adjust-
ed. Using the fleece hook-and-loop straps, the
slack in the seating surface can be changed so
that it suits your seat cushion system. In doing
so, the seat cover should not have too much
slack to avoid touching the frame cross tubes.
