18.3 Ergonomic back shell & its setting
options
The "ergonomic back shell" back system con-
sists of an aluminium shell, Velcro cross-straps
and back padding.
Slack
is already integrated into the back shell
due to its shape. It cannot be adjusted.
However,
lumbar support
can be adjusted
individually using the Velcro cross-straps. For
this purpose, the back padding is removed
over the Velcro straps. The cross-straps can
now be tensioned according to the individual
requirements by releasing and refastening the
Velcro strap system.
