1. OUTER SHELL: Designed to dispense energy in
an impact and protect from debris penetration.
The shell is made of an ultra-light weave of carbon
fiber. It’s hand-formed in a two-piece mold, then
trimmed by a computer-controlled machine.
2. NOMEX LINING: Designed to transfer heat away
from a driver’s head, while absorbing sweat. The
thin fireproof layer is made of Nomex and rayon
and covers the inside of the entire helmet.
3. HELMET REMOVAL SYSTEM: A small airbag
that can be inflated through a valve by safety
crews allows the helmet to be lifted from the driver
without neck strain. It was mandated by INDYCAR
4. AERODYNAMIC PLATE: A small piece of outer
shell attached to divert air into a gap beneath it to
create downforce to stabilize the helmet. Air flow
across the top of the helmet is directed into the
engine air intake, located behind the driver’s head.
5. AERO WICKERS: Thin strips of rubber attached to
each side and at the back of the helmet to prevent
the driver’s head from being “buffeted” by 200
mph air resistance. It also prevents air backdraft
from trying to lift off the helmet. The shape is
adjusted for each track.
6. INNER LINER: Made of a single molded piece
of high-tech, lightweight bead foam, this is the
helmet’s skeleton and the primary protective layer
in an impact. It spreads both interior and exterior
impact forces across a large area to protect
7. FIT PAD: Foam that surrounds the sides
and back of the head, glued to the inner
liner. Thickness adapted to head size.
8. EARPIECE: Allows the driver to
hear in-car radio communication
from the spotter and pits and
protects the driver’s ears from
engine noise. Also included is
the INDYCAR Earpiece Sensor
System, which measures
the forces a driver’s head
experiences in an impact.
9. NECK PAD: A strip of plush, opencell
foam attached to the inner
liner at the base of the helmet.
Like the fit pad, it is custom-made to ensure a tight fit around the neck. It also helps
repel flames from the head and face.
10. CHIN STRAP: Kevlar strap secures the helmet
to the driver’s head. It is replaced after minor
11. LID BALANCE: A part of the outer shell, it is a
crucial aerodynamic aid to stop the driver’s head
from being blown back at speed.
12. FRONTAL LINER: Extension of the main foam
bead lining to protect the face in impacts.
A microphone is imbedded into the foam in
front of the driver’s mouth for in-car radio
communication. Also houses the tube connected
to the drink bottle installed in the front of the car.
13. VISOR: Able to repel fire for at least 45 seconds,
the Lexan face shield is specially coated on the
inside to prevent fogging. On the outside, three to
five transparent, thin plastic "tear offs" allow the
driver to periodically refresh his/her view.
14. VISOR STRIP: A reinforcement panel made of
carbon fiber and Zylon that runs across the top
of the visor and the portion of the helmet exterior
above the visor, helping protect the driver's head
from debris impacts.
