SIMPSON PERFORMANCE PRODUCTS SAFETY BULLETIN

DECEMBER 2015

SFI 16.6 Certified seatbelts are the strongest restraints available to racers. Always a leader in implementing the best in safety practices, NASCAR now requires SFI 16.6 belts for Sprint Cup and Xfinity Series with the NASCAR Truck Series mandating SFI 16.6 for the 2017 season.

The SFI 16.6 specification adds additional safety standards to the SFI 16.5 standards. The biggest change required in SFI 16.6 versus SFI 16.5 is the addition of a mandatory Negative G belt, making all belts either 7 or 9 point configurations.

The Negative G belt is a center mounted sub-strap that acts to hold the camlock and lap belts in position on the pelvis bones during a roll over or negative G incident. The Negative G belt is mounted following the plane of the driver's chest straight to either the seat itself or the floor depending on your seat. By adding the Negative G in addition to the anti-submarine belts, an SFI 16.6 belt ensures the driver has optimal seat belt geometry in both a frontal accident and a rollover accident.

Additionally, SFI 16.6 adds an increased level of tensile strength testing of all individual components of the harness as well as testing of the mounting hardware, latching hardware and adjuster hardware for tensile strength. The tensile test requires that each individual belt component withstand a test load without failure or slippage. The amount of load applied is determined by the body location and type of individual belt but all components must be capable of sustaining the load for 5 seconds, twice without failure. A single shoulder belt and its mounting hardware is tested to 3,500 lbs. of load, a double shoulder belt requires that the 3" body belt withstand 3,500 lbs. of load and the 2" over (HNR) belt withstand 2,500 lbs. Lap belts and mounting hardware must be able to hold 3,000 lbs. For single sub-straps, each sub-strap is loaded to 3,000 lbs. while for a T-bar style sub-strap the required load is 4,500 lbs. with both sub-straps being tested at the same time. The Negative G belt is tested to 4,000 lbs. by itself whether it is standalone or part of a T-bar setup.



Seatbelts are your most important piece of safety equipment. Simpson Performance Products has a full line of SFI 16.6 seatbelts and can provide our customers with as many options as possible. We offer both 2" and 3" lap belt configurations. Numerous mounting brackets and hardware have been approved for SFI 16.6 to be used for shoulders, laps and sub-straps. Simpson manufactures custom sewn harnesses for professional drivers in our North Carolina facility.
