Ventilation system 3 – head ventilation
(Proactive-Dynamic-Ventilation-System)
To provide ventilation to the surface of
the head, two air inlet fairings are fitted
on the upper side of the helmet shell. Air
entering these inlets is guided effectively
via channels to the top of the head. The
advanced cushion system inside the helmet
allows direct contact between incoming air
and the head, making the collection and
removal of heat from the interior through
the air outlet vents on the rear of the
helmet and in the embedded mesh fabric
in the neck area. Moving the ventilation
sliders to the rear position opens the
ventilation channels in the helmet; if they
are in the forward position, the ventilation
is closed. The level of ventilation varies
with the current speed and sitting position.
The maximum volume of air intake is
obtained by assuming a sports sitting
position.
Ventilation device 4 – interior air extraction
The SR1 is equipped with a constant air
extraction system. Air present in the
interior and entering via the ventilation
is guided via channels towards the rear
of the helmet. The reduced pressure
present to the rear of the helmet ensures
a constant suction of the air from the
inside through the air outlets under the
spoiler and in the special mesh material in
the neck cushion ensuring a comfortable
temperature inside the helmet.
