Inner oscillating shell (fig. 5 - B/C), consisting of low density
polypropylene foam (PPE) to provide gradual absorption, was
designed to rotate inside the helmet, working in conjunction
with the Main inner shell. This system enables multi-
directional sliding that also dissipates the energy associated
with rotational acceleration, so as to improve protection in
case of rotational impact.
LEAS – Limited Extension Anti Shock
The Diamond Helmet is also equipped with foam protections
(fig. 6). One of these is located at the bottom of the chin-
rest, and the other at the back at the base of the neck. This
advanced protection system represents an important advance
in the containment of the front and back neck flexion and in
impact dissipation in the event of a fall. This system can work
in conjunction with modern neck braces.
