This rule is effective
immediately. If your car does not comply you will
not pass tech and will not be allowed on the track.
This rule only applies to
vehicles with aftermarket installed safety restraint
systems.
If you have the OEM 3 point seat belts installed these
are perfectly acceptable for use in a DE event.
Harness Systems: If the participant chooses to install a
5 or 6 point driving harness, several changes to the
automobile must be made to create a safe occupant
restraint system. Harnesses must include an
antisubmarine strap and be mounted in an approved manner
consistent the manufacturer’s instructions. The Harness
system must be used in conjunction with a seat which has
the supplied routing holes for the shoulder and
anti-submarine belts. All pieces of the restraint system
must be installed in accordance with the manufacturer’s
instructions.
This means that a seat is required to have the proper
routing holes for the harness as supplied by the seat
manufacturer for the shoulder and anti-submarine straps.
The shoulder straps should be mounted at 90 degrees to
the axis of your spine or at most 40 degrees down from
horizontal. Because the addition of the harness system
means that the occupants are fastened upright in the
vehicle, a properly padded roll bar or roll cage is
strongly encouraged to complete the SYSTEM. The use of
one without the other may result in an unsafe
environment and is not a COMPLETE SYSTEM.
Due to UV degradation and wear the harness webbing must
be replaced every five years.
In general 4 point restraint systems that do not
incorporate antisubmarine technology are not allowed.
The exception to this rule is if the vehicles owner can
produce documentation proving certification by the
manufacturer that the 4 point system incorporates
antisubmarine technology then this system will be
allowed provided it is installed in compliance with the
manufacturers instructions
PCA Harness Standard Amendment effective 3/2008:
In addition to the standard SFI and/ or FIA approved
five and/or six point system, the standard will allow a
four point system that meets the following requirements:
1. Meet the Federal Motor Vehicle Safety Standard 209
2. Attaches to the factory seat belt mounting points
3. Each belt is designed to work in a specific vehicle
and that vehicle tag must be attached to the belt system
An example of a system that meets the above criteria is
the Schroth Quick Fit system.
