HANS ANCHORS
EXPLANATION
COLLAR
STYLE POST ANCHORS:
For 2011, the Snell foundation has announced a helmet standard
(SAH2010) that allows helmet makers to permanently bond a
nutwasher inside their helmets. This makes attaching a HANS Device
helmet anchor easier as you simply screw the anchor into the
helmet. As you know from past anchors, the point of the post
anchor and the tethers of the HANS Click Quick anchors should
point rearward after installation. Older helmets with a moveable
nutwasher inside the helmet can orient the anchor by rotating this
inner nutwasher. As this is not possible with the SAH2010 fixed
nutwashers, HANS has designed a collar system that can be rotated
from outside the helmet. These anchors ship with a small wrench
designed to facilitate this feature.
The
old-style post anchors will be phased out and replaced with the
Collar Style Post-Anchor (see pictures below).

QUICK
CLICK ANCHOR: The Quick Click anchor attaches
directly to the helmet and is fully compatible with sliding
tethers.

What
is the difference between an SA2010 Rating and SAH2010 rating?
The
new Snell SA2010 rated helmets are being phased in.
What is new is the addition of the SAH2010 rating. This rating is
an addendum to the SA2010 rating. When you look inside your new
helmet, you will see one or the other. A SAH2010 helmet can be
used anywhere a SA2010 helmet is allowed. What exactly is the
SAH2010 rating?

The extra "H" indicates FHR (frontal head restraint)
capability. The Snell SAH10 rating applies to helmets that are
supplied with built-in Hans Device connection points - two sets of
M6 threads where the device anchors are typically installed.
Due to an FIA homologation, many new helmets are manufactured with
such terminals pre-installed. The Snell Foundation verifies
the location of the mounting points and tests the submitted
helmet's pre-installed fittings for strength.
All
SAH2010 helmets will have a pre-installed HANS Device Mounting
Point (M6 threaded hole for the anchor to mount into when it
leaves the factory). Note that the entire device anchors are
NOT pre-installed. Only the M6 threaded nut washer between
the liner and shell is installed into the helmet. The
customer is responsible for installing the outer portion of the
anchor (screwing the outer anchor part into the helmet).

The
M6 mounting points that the anchors attach to are built into the
SAH2010 rated helmet.
The customer can screw in their anchor to the already installed M6
threaded hole.
SA2010
helmets may or may not be pre-drilled with holes for a head and
neck restraint. They do NOT have a pre-installed
mounting point (M6 threaded hole). The customer is
responsible for installing both the M6 mounting point between the
liner and shell and the top part of the anchor that screws into
the M6 nut washer.
To
make it easy, think of the SA2010 and SAH2010 as equal, and both
will pass the same technical inspection. The difference is
the SAH2010 has the pre-installed mounting points and is ready
to accept your head & neck restraint's anchors.
Changes
in 2010 Snell Helmet Ratings
Racing
safety standards have come a long way.
However, helmet technology will take another step forward
as manufacturers begin to offer a new generation of helmets
designed to meet the new Snell Foundation 2010 certification
standard. This new
standard, which incorporates a radical shift in the way that
helmets are tested and constructed, will result in helmets that
are both much lighter and much safer than ever before.
In order to understand what this new standard will mean to
you, here is a brief overview of changes you can expect to see.
The
biggest change in the new helmet safety standard is they are going
to adopt variable head-form sizes.
In prior Snell standards, they tested the helmets using a
standard sized “dummy” head with a standard circumference to
mimic the size, shape and weight of a human head.
The new 2010 standard is going to require a number of
variable head forms that will better approximate the cubic mass
and circumference relationship of various head sizes.
Everyone obviously does not have the same head size, so
Snell is requiring the manufacturers to create six different head
forms to test.
Every
helmet size will be a little more unique.
Manufacturers are going to have to change construction
somewhat between sizes in a given model and this is requiring them
to look at new, advanced shell construction methods to give them
as light a weight shell as possible that’s also as strong as
possible. For
each helmet tested, it is dropped twice and there are different
criteria for the first and second drops depending on head form
size.
Since the helmets will be properly sized to the actual head
geometry of the racer, it’s going to be a better helmet because
it’s not going to shift or move during an impact.

With advances in head and neck restraint systems (HNR), the
new Snell standard will have a component that will test for
compatibility of the helmet shell with the HNR.
The attachment anchor points (where the device attaches to
the helmet) will require proper reinforcement in those areas to
withstand lateral shear force that they may see in an impact.
Manufacturers will most likely view the helmets and HNR as
part of an overall driver safety system.
Snell introduces new helmet
ratings every five years. When the
SA2005 standard was introduced, most racing organizations started
phasing out the use of SA95 helmets. We anticipate that
SA2005 helmets will be accepted with most racing organizations
through 2015 (check with your racing organization's rules to
confirm). For
those interested in getting one of the new SA2010 & SAH2010 rated helmets, availability from manufacturers
began in October 2010 and will be be phased in throughout 2011.
