SCHROTH FHR specific 6-point Flexi harness - the benchmark for professional racing harnesses as used by top OEM's and race teams world-wide, cosniting of user-friendly pull-up or pull-down adjustment with multiple options for installation makes this the ideal harness for specifying your custom harness without the custom cost.
Technology
Flexi Belt
One Harness, many variations!
Length adjusters in lap belts come as "pull-ups" or "pull-downs". In addition they often have to be positioned differently to acheive optimal operation. Schroth has developed the soloution which covers your different needs with just one lap belt model: the "Flexi Belt". The lap belt latches and brackets supplied with the harness can be assemblerd to the lap belt with a two-bar sliding bracket allowing you to change the configuration. With this you decide on Pull-up or Pull-down versions and if applicable, different for the left and right lap belt portion. You may also vary the lengths to optimise the adjuster position depending on your car, your seat and seating position.
- 2" (50mm) FHR Specifc Shoulder Belt
- 2" (50mm) Flexi Lap Belt
To explain why 50 mm (2") webbing is more effective that 75 mm (3") webbing, one needs to look at the shape of the human body. The Iliac Crest (IC) is the part of the pelvic bone that sticks out above the hips. 50 mm (2“) webbing fits entirely within the recession created by the Iliac Crest, where 75 mm (3“) webbing rides over the top of the Iliac Crest. The 75 mm (3“) webbing has less contact area by percentage than the 50 mm (2“) webbing which will cause more bruising during an impact where the belt is making contact with the pelvic bone. Since the 50 mm (2“) webbing rides inside the Iliac Crest it can be worn as much as 25 mm (1“) to 40 mm (1.5“) tighter and at the same time is more comfortable. Since the 50 mm (2“) webbing fits well within the Iliac Crest of the pelvis, it is less likely to slide up above the crest and cause submarining a condition where the body slides down below the lap belt possibly causing internal organ damage.
Research shows that the faster the pelvis is captured, the lower the resultant loads on the chest, head and neck. There is no difference in the strength of the 50 mm (2“) webbing. All webbing: 50 mm (2“) or 75 mm (3“) must meet the same homolgation test loads.
An additional benifit of the 50 mm (2“) lap belts, the required force to properly and tightly adjust the belts in the cars is much easier than with 75 mm (3“) belts.
FHR Specific Harness
The concept of the FHR specifc restraint is quite simple, Schroth designed a belt which fits cleanly and completely onto the surfaceof the FHR without any extra webbing to hang off the side of the FHR. The fitment of the 2" webbiong on the FHR allows for secure and optimal routing of the restraint. With the intorduction of the FIA 8853-2016 standard for restraint systems, a full 2" shoulder belt version may now be used as well the 2"/3" shoulder belt combination.
Aluminium Rotary Buckle
Newly designed compact aluminum rotary buckle features a quicker, more positive "click" and ergonomic release lever.
Webbing
Webbing that makes the difference! The webbing Schroth Racing use is especially designed and manufactured for SCHROTH. Each lot manufactured must pass their stringent quality control procedures.
SCHROTH only uses Polyester material. Polyester has advantages over Polyamide (NYLON®) webbing.
Advantages, such as lesser degradation under light (see figure 1) and a resistance against acids like battery acid. In addition Polyester does not absorb moisture so the performance of SCHROTH harnesses do not change whatever the climate may be. Polyester also has a better force/elongation ratio so a well designed webbing can dissipate more energy during an accident. Unique to SCHROTH is the "memory effect“ Schroth have designed into their webbing. Special mono filaments laterally woven in, perform like small leaf springs and keep the webbing flat. This results in better load spreading over the full width of the SCHROTH webbing. An additional advantage of the SCHROTH webbing: The special weaving technology forms round edges for additional comfort (see figure 2).
