comes with a standard olive drab walnut flour finish and
black rubber edge beading. Two adjustable hanger tabs at the
front of the shell facilitate attachment to the headset and
allow for fitting adjustments. A snap on the back of the
helmet shell permits the attachment to the adjustable rear
attachment tab on the modified CVC liner.
The modified CVC liner affords optimal fit, comfort, and
stability. It consists of energy-absorbing foam pads
enclosed in aramid mesh fabric. The energy-absorbing pads
feature a more ventilated surface than earlier-style pads,
thus making the helmet more comfortable for extended wear.
An aramid simplex front brow pad cover enhances comfort at
the upper forehead area. The liner offers the following
Adjustable front liner hanger tabs. These prevent shell
rotation and a fitting adjustments after the liner has been
installed within the helmet shell.
Adjustment Strap. This feature allows for adjustment of head
width and earcup height and prevents the earcups from moving
out of the circumoral region when the chinstrap is secured,
a key improvement in maintaining sound attenuation.
Adjustable Tab. This facilitates attachments of the CVC
liner to the snap on the rear of the helmet shell and
prevents forward rotation of the helmet.
strap with hook-and-pile-closure. This redesigned, one
handed strap affords a snug fit in the nape area with
increased shear strength due to the loop back design.
to the CVC liner via snap fasteners, is constructed of woven
aramid webbing with an adjustment buckle.
rotatable earcups are designed for a secure fit and optimum
sound attenuation. The earcups can be adjusted vertically
via the adjustment straps on the CVC liner. A tension spring
adjusts pressure of the earcups to the crewmemberís head. A
raised ring on each padded, non-hardening, polyurethane
earseal further enhances the fit and sound attenuation with
minimal pressure to the head.
The DH-132S/DH-132AS is equipped with an MK-1697/G
communications kit (or other optional kits) which includes a
microphone (dynamic or noise canceling electret), two
earphones (one installed in each earcup), a cordset with a
lower AP-107XL plug, and a radio-intercom switch.
A retainer strap is attached to the rear of the helmet shell
to secure the Sun, Wind, Dust, Goggle strap to the helmet.
ACCESSORIES / OPTIONS:
An optional Active Hearing Protection (AHP) talk through
system is available for use with the DH-132S/DH-132AS. This
battery-operated system allows the crewmember to have noise
attenuation plus the ability to hear conversations clearly;
it also helps protect the crewmemberís hearing by
suppressing noise levels above 85 decibels. The AHP system
consists of an outside communications module on the left
earcup (as worn) and a rotary switch on the right earcup.
Alternatively, the AHP feature is available from Gentex in a
self sustained plug-in module which is worn on the body with
a clothing clip.
(ANR): ANR is available as an option for increased
attenuation at the lower frequencies 31.5 through 1000
Conversational Communications Unit: The DH-132S/DH-132AS
will accept a modified Conversational Communications Unit
(Model 6011) which is designed to provide two-way
communications for the user when they are disconnected from
the vehicle communications system but while wearing the
helmet and a chemical defense mask with integrated
The MK-1697/G headset-microphone can be modified by
installing a transformer and diode capacitor network in the
left earcup to permit the use of a high performance electret
microphone with superior noise canceling characteristics and
improved EMI performance.
A protective faceshield designed for use with the
DH-132S/DH-132AS helmet and provides limited ballistic and
impact protection in the eye, face, and jaw regions. The
faceshield attaches to the front of the helmet and may be
stowed on top of the helmet when not in use.
The visor housing kit consists of a U.S. Army helicopter
pilot type protective visor housing and a single
polycarbonate visor. The visor housing attaches to the front
of the helmet shell and contains a knob for raising or
lowering the visor. A clear, neutral or laser visor lens may
The DH-132S/DH-132AS ballistic helmet shell assembly limits
the acceleration of a test headform to less than 75gs when
subjected to two identical impacts from an 18 inch drop
using a hemispherical anvil, (ANSI-Z90.1 test method used).
The DH-132S has a non-ballistic fiberglass shell. The
DH-132AS helmet shell has an aramid shell with a V50
ballistic rating of not less than 1400 feet per second when
tested in accordance with MIL-STD-662. Higher resistance
shells are available on special order.
The DH-132S and DH-132AS with the improved inner liner and
shell adjustment straps reduces the number of sizes required
to fit the majority of users. Available in three sizes
(small, medium, large, and X-large). The medium and large
fits 90 percent of the users with minimal adjustment. The
helmet shells are available in 2 sizes. The result is an
almost universal size system except for the special case in
either end of the population range.
