D. THE HELMET
in autumn/winter you can reduce
the volume of incoming cold air, or
divert it, by covering the ventilation
channels with the flaps of the crown
liner. To do so, raise the middle
section of the crown liner slightly
and fold out the fabric flaps located
behind the front section.
Ventilation device 4 – interior air extraction
The C3 Pro is equipped with an
innovative air extraction system.
Fresh air flowing in through the
head vent is directed via the air
channels in the inner shell to the
back of the helmet. The reduced
pressure that prevails at the back
of the helmet ensures that the air
is constantly sucked out through
the air vents and special netting
material fitted to the neck pad,
thus guaranteeing a pleasant
climate inside the helmet.
Ventilation device 5 – minimum level of fresh air
The special shaping of the top of the
chin vent provides the helmet with
a guaranteed minimum ventilation
function that ensures a constant
supply of fresh air. The air entering
in this way is regulated so that the
rider barely notices it, but it provides
an effective supply of fresh air from
40
a speed as low as 30 kph (provided
the helmet is positioned fully in
the air flow when travelling). This
function counteracts any build-up of
mist on the visor and any excessive
concentration of CO
, even when the
2
helmet is fully closed.
15. ADDITIONAL SAFETY FEATURES
Anti-roll-off system (A.R.O.S.)
The anti-roll-off system specially developed by SCHUBERTH and
provided as a safety feature in every SCHUBERTH motorcycle hel-
met ensures that, when the chinstrap is fastened (see section
D.10. for operation of the chinstrap/fastener system) and correctly
adjusted
a) the helmet cannot pivot off the
head from behind,
b) the risk of contact between the chin
section of the helmet and the chin
or neck of the rider is minimised due
to the low angle of tilt and
c) the consequences of the helmet
hitting the rib cage as the result of
an accident are reduced.
