7. Each time the harness is worn, check to insure all
latches are secure. “SEAT” the harness, by pulling
up on the helmet tethers before attaching the
quick release to the helmet. This will take out
unwanted slack in the system.
Minor adjustments may be necessary to
properly tension the harness each time
the system is worn.
Some of the factors that can
influence the harness fit are:
1) Driving suit fit – a loose fitting
driving suit will allow the harness
to better fit the occupant. It will also
allow the fire suit to increase it’s effectiveness
in a fire by providing air gaps.
2) The seat and seat belt tension can also
change the routing distance and thus
require harness adjustment.
SAFETY SYSTEM
A Safety Solutions head and neck restraint, Huchens Device, is only one part of a good safety system for any
race car. It is very important to make sure all of your safety equipment is in top shape and interacts well with
the other components of your safety system.
A Hutchens Device has been shown to be most effective in a system with properly mounted seat belts and a
6-point sub-belt system. The 6-point has been shown to better control the occupant’s pelvis earlier in the event.
By securing the pelvis earlier in the event, the upper torso and head loads will be reduced.
A rib support seat with shoulders and a quality head rest has also shown to be beneficial to the effectiveness of
the harness system. The seat should be securely mounted and have a ramp-up to the front of the seat to help
reduce the occupant motion in a frontal or angular frontal impact. The rib support seat will help slow down the
upper torso and cause the body to curl around it. This motion will increase tension on the vertical straps of the
harness.
A quality headrest and nets will help the occupant stay inside of the safety system and will help guide the head
during the event. Contact with the steering wheel in a stock car is very likely. For this reason, a wheel with thin
or relieved spokes and a column that can stroke can help control the head motion in an impact. This is the same
principal that is used in your passenger car.
Head and neck restraint devices are most effective in angular frontal and frontal crashes. They become less
effective in side and rear impacts. The occupant needs to rely on the other parts of the safety system in these
types of impacts. The seat and headrest is the main restraint in side and rearward impacts.
As with any restraint system, replace after severe use, or after 3 years of use.
