COMPONENT DESCRIPTION
Helmet Shell (Figure 2)
The lightweight composite
helmet shell protects the head
from impact. Chafing pads
prevent the earcups from
chafing against the side of the
shell. Cross straps control
earseal compression for
optimum fit and noise
reduction.
Energy-Absorbing Liner
and TPL (Figure 3)
The energy-absorbing liner
and the preformed TPL
replace the sling suspension
systems of earlier SPH
models.
The energy-absorbing liner is
molded from rigid polystyrene
and is designed to absorb and
reduce impact forces to the
head. It is attached to the
inside surface of the helmet
shell with hook-and-pile
fastener.
The TPL consists of molded
layers of plastic and a
removable, washable cloth
cover. The sides of the
cloth cover are made of pile
fastener that attaches the
TPL to the hook fastener on
the inside surface of the
energy-absorbing liner.
Preformed in three sizes
(small/regular, regular, and
extra-large), the TPL fits
most heads. However, if
necessary, the TPL can
be heat-softened and
custom-fitted to an individual
head shape.
