RACING & STREET LEGAL HARNESSES
INTRODUCTION
INTRODUCTION
For over 60 years SCHROTH has been manufacturing racing, tuning (street legal), and specialty harnessbelts. Since 1960 SCHROTH has been conducting ongoing simulations and crash tests to increase performance and to perfect the quality and design of every restraint. The information learned from many of these tests has been used by major safety organizations and sanctioning bodies to further improve their safety standards. SCHROTH continues to be the technology leader in racing, aviation, and military harnesses. Examples of SCHROTH innovations include the development of the asm® safety system, the patented RFR™ rotary buckle (cam lock), and the patented HYBRID™ restraint. As a licensee to manufacture and distribute the HANS® device, SCHROTH continues activities to further develop the HANS® device through extensive HANS® testing.

COMPETITION HARNESSES
Hybrid Competition Restraints
Typical Formula (D-Ring) restraints display high upper torso trajectory during a crash. To reduce this trajectory, the crotch straps have to be routed backwards and to be worn extremely tight. Some drivers complain of reduced blood flow in their legs. In addition, this configuration is not as effective in rear impacts at keeping the buckle and the lap belt in the correct position. In particular in typical open-wheel race car seating positions the driver is not kept firmly in his seat but is likely to move up exceeding the roll over protection bar. The so called T-bar 6-point belt design provides a better restraining function since the anti-sub straps can be routed downward and slightly rearward from the chest/crotch tangential. This keeps the buckle in place and provides direct load transfer from the shoulder straps into the anti-sub straps. During a rear impact the anti-sub straps keep the buckle and lap belt in place and restrain the driver much better in the seat.
10
The disadvantage of a T-Bar style restraint is that some people complain that the anti-sub strap bracket rubs on the inside of their upper thigh. To increase comfort, the buckle is often not worn as low as it should be for best lap belt positioning. The design of the T-Bar also precludes the addition of a 7th point sub-strap.
The solution: the revolutionary SCHROTH Hybrid™ Restraint. The crotch straps are not routed through D-rings or attached to a T-Bar but are held directly by the specially developed lap belt latches.Thanks to the patented SCHROTH RFR™ rotary buckle the load tranfer from the shoulder belts through the buckle into the anti-sub straps and vice versa in case of a rear impact is achieved. This direct load transfer is important for optimal restraining performance.

COMPETITION HARNESSES
Profi Competition Restraints Double Shoulder Belts
The Profi series of harnesses are designed as professional level restraints with 4, 5, or 6 points. The defining characteristic of a Profi Harness is the anti-sub strap mounting method. The anti-sub straps mount to a latch that fits into the bottom of the Cam lock. In 6 point variants this latch is what is known as the “T-bar” as it resembles an upside-down “T”. In 5 point variants there is a single latch. Profi harnesses are available with either Pull Up or Pull Down adjusters on the lap belts. Most 2” Lap versions feature Flexi-Belt technology allowing the end user to change adjusting directions. 2” versions are available with sewn-in Bolt-in end fittings for installation in tight spaces. 3” lap versions have sewn-in end fittings. Profi Harnesses are our first recommendation for production based race cars and anything with an upright seating position.
12
These harnesses carry FIA homologations. SFI 16.1 homologation available on some belts by special request.
Pioneered in Formula 1, these shoulder belts offer the highest level of safety available. Features a 3” belt over the body, and a 2” belt over the HANS® device - effectively sandwiching the device between the two belts. Testing has shown that by mounting the Body Belt at a downward angle of 20º-30º and the upper 2” HANS® belt at a downward angle of 10º improves the performance of the HANS® by 50% over a standard installation. In addition, loads in rear end impacts and rollovers are reduced as the body is more effectively secured. Installation is more complicated with the Double Belt so be sure to consult SCHROTH or your dealer before purchasing. We offer a weld-on bracket to aid in the installation.

The “ZIP Adjusters” have been integrated into the lap belt buckle attachments to optimize the position of the adjusters for optimal adjustment. The design of the new “ZIP Adjusters” allows for exceptional ease of adjustment (tightening) and release for faster and smoother driver changes. These adjusters are also found inline on the shoulder belts. SCHROTH has also added some nice touches to these harnesses that make life in a race car much easier. There are extra large, easy to see Yellow “hand loops” on the lap belts to make adjusting faster and easier. The loops on the shoulder belts aren’t yellow, but they are there and easy to use. Clearly marked release straps are sewn onto all adjusters so it is easy to see what needs to be pulled to get a driver out of the car. The Enduro Belt is only available in black, but it is available with HANS® specific 2”/3” shoulder belt combination as an option.

Formula cars require a different breed of restraint. Drivers are often sitting on the floor of the vehicle, and attachment points for the harnesses are sometimes the same for lap belt and anti-sub strap. Couple this with an extremely laid back driving position and your best bet is a Formula style restraint. Formula style restraints are characterized by the D-rings sewn on the lap belts through which the anti-sub straps are routed. They are then looped around the shoulder belt latches. Formula belts do not come with inline lap adjusters. Lap belt length is adjusted at the boltin point. For speciality Formula car applications we have one design with a limited pull-up adjuster on each side. These are the most popular choice for Formula 1, IRL, Formula Atlantic, Formula Nippon and many vintage racers.
Pioneered in Formula 1, these shoulder belts offer the highest level of safety available. Features a 3” belt over the body, and a 2” belt over the HANS® device - effectively sandwiching the device between the two belts. Testing has shown that by mounting the Body Belt at a downward angle of 20º-30º and the upper 2” HANS® belt at a downward angle of 10º improves the performance of the HANS® by 50% over a standard installation. In addition, loads in rear end impacts and rollovers are reduced as the body is more effectively secured. Installation is more complicated with the Double Belt so be sure to consult SCHROTH or your dealer before purchasing. We offer a weld-on bracket to aid in the installation.

COMPETITION HARNESSES Double Shoulder Bracket
Lap Belt End Fittings
B14 - For use with Schroth Eye Bolts
Although it is possible to mount the Double Shoulder belts to one single harnessbar, it is recommended to use this Double Shoulder Bracket to vertically separate the shoulder belt anchor points. Doing so allows optimum capturing of the HANS® Device as well as comfort for the driver. Must be welded to harness mount bar. This bracket may also be used to adjust the height of the harness mount for a standard harness where the harnessbar is too low or too high; made of unfinished steel. Once welded it will need paint. Please reference the SCHROTH Installation Instructions prior to welding. to be sure that you have placed the brackets in the correct location for the shoulder belts.

COMPETITION HARNESSES 2001
SCHROTH‘s entry in NASCAR begins at the annual Performance Racing Industry show when Penske driver Ryan Newman and Crew Chief Matt Borland stopped by the SCHROTH booth. They liked what they saw with SCHROTH’s new Hybrid™ anti-sub strap technology and introduced SCHROTH to NASCAR
2004
SCHROTH rides to the NEXTEL Cup Championship with Kurt Busch. Six of the “Race for the Chase” drivers were using SCHROTH.
2005
SCHROTH becomes one of the first harnessbelts to receive NASCAR certification under NASCAR’s new seat belt safety standards. Ryan becomes the first driver to run a SCHROTH belt in the “Cup Series” in September at the New Hampshire International Speedway - it turns out to be his first Cup Series win!
SCHROTH introduces 13 different Harnessbelts to NASCAR under the new SFI 16.5 belt standard. Ryan Newman breaks new ground again with SCHROTH by being the first to run our new “Double Shoulder Belt” restraint. NASCAR testing showed that the SCHROTH Double Shoulder Belt which “sandwiches” the HANS improves driver comfort and overall performance of the HANS®. By mid season 19 Cup Drivers are using SCHROTH belts including five “Race for the Chase” drivers.
2003
2006
2002
SCHROTH popularity grows as NASCAR drivers find that our HANS® specific 2”/3” shoulder belt rides better on the HANS® ; reduces problems with the tight belt openings between the seat backs and harnessbar; and eliminates the annoyance of any webbing hanging off the side of the HANS®.
SCHROTH continues its reign as the first choice for Harnessbelts for top NASCAR teams - landing in the champion’s cars in the NEXTEL Cup, Busch and Craftsman Truck series. Six of the ten Chase contenders used SCHROTH.
2007
SCHROTH introduces the 2” lap belt to NASCAR and proves that the superiority of 2” lap belts is profound enough for SFI 16.5 Homologation. 29 Cup Drivers choose SCHROTH Restraints. Eight Chase contenders use SCHROTH including Champion Jimmy Johnson.
COMPETITION HARNESSES 2008
Eight Chase contenders use SCHROTH including 3rd time Champion Jimmy Johnson. SCHROTH is the leading belt in the Cup Series with over 30 drivers running our belts. The 2” lap belt gains wide acceptance with nearly half of the SCHROTH drivers selecting this option.
2009
SCHROTH continues its domination in NASCAR with more drivers using SCHROTH in the top three series than any other belt - including nine of the Chase contenders.
The choice is yours.

COMPETITION HARNESSES
Latch Link Harnesses Why Latch Link? For the past 60 years, SCHROTH has been pushing at the forefront of technology in the Motorsport Safety business. We have stood behind our Cam Lock systems for every application. Our Cam Lock has withstood the sand and heat of the deserts of Iraq in several military applications. Regular exposure to mud and water however are better handled by the classic Latch Link type connection system – one much less affected by the elements. Drawing on the ties made in NASCAR’s Sprint Cup, SCHROTH partnered with Kasey Kahne’s USAC and Outlaw operations to come up with the highest quality Latch Link Harness using the best of SCHROTH’s Technology. Better yet our Latch Link belts are made in the USA – not imported from the far east. Our Latch Link belts use the same unique Polyester webbing and lightweight hardened steel adjusters used in all of our Cam Lock harnessbelts. Polyester is the ideal webbing material for situations where the webbing may frequently get wet and/or muddy. Polyester retains its strength and elasticity in situations that Nylon webbing virtually fails. See
SCHROTH’s LatchLink Harnesses are made in the USA and have many features that distinguish them from other belts.
COMPETITION HARNESSES
End Fitting Options page 43 for more information about SCHROTH’s unique Polyester webbing. Another benefit of the Latch Link harness is a lower price. Not everyone is running on a Formula 1 budget but that does not mean that you shouldn’t buy the best safety equipment you can afford. Our SFI 16.1 homologation harnesses are available in nearly every possible configuration. Three styles of shoulder belt are offered, the standard 3” shoulders, a 3” V-Strap shoulder, and the venerable 2”/3” HANS® specific shoulder designed to maximize the efficiency of your HANS®, Hybrid, or Defender head and neck restraint. You can also choose where you want your Lap adjusters, or if you want them at all. Right hand lap? Pull Up? No Problem. No adjusters? Sure thing. The harnesses all ship open ended. If you need boltin or snap-in end fittings for any of the points, you need to specify that when ordering. The V-Strap shoulder is an exception - its bolt-in bracket is sewn in. The flexibility of the Latch Link belts, combined with the affordable price make these belts the perfect choice for a grassroots racer who is concerned about safety.

A closeup of the SFI 16.5 2” and 3” pull down lap belts. “Zip” adjuster shown in front.
What is different with our SFI 16.5 Latch Link Harness compared to our SFI 16.1 Harness? First, the SFI 16.5 standard allows for 2” lap belts where SFI 16.1 only allows 3” lap belts. Most sanctioning bodies that recognize SFI 16.5, now also allow 2” lap belts. Read up on the advantages of 2” lap belts on page 42. We have the complete line of SFI 16.5 configurations in both 2” laps and 3” laps. The testing requirements for SFI 16.5 belts are much more involved than for SFI 16.1. First, the webbing test load is increased by 1,500 pounds over SFI 16.1 requirement. Regardless of whether the webbing is 2” or 3” the strength and elongation rates must meet the same test. SFI 16.5 also includes an additional test for abrasion of the webbing not included in the 16.1 test. The
30
body block load is also increased. The adjusters in our 2” SFI 16.5 lap belts incorporate our latest “Zip” series of adjusters (see page 45). The Zip adjuster is the smoothest and easiest adjuster on the market, allowing you to get your lap belt tighter than you ever thought possible. We offer all combinations of adjuster locations with Pull-Up or Pull-Down on either or both sides - or if you choose, no adjusters at all.
NOTE: The lap belts and shoulder belts come only with the 3 bar bracket for wrap mounting. You must order the additional hardware for either bolt-in or snap-in installations. See page 27 for mounting hardware options. Sub-straps come with bolt-in brackets.

Pioneered in Formula 1, these shoulder belts offer the highest level of safety available. Features a 3” belt over the body, and a 2” belt over the HANS® device - effectively sandwiching the device between the two belts. Testing has shown that by mounting the Body Belt at a downward angle of 20º-30º and the upper 2” HANS® belt at a downward angle of 10º improves the performance of the HANS® by 50% over a standard installation. In addition, loads in rear end impacts and rollovers are reduced as the body is more effectively secured. Installation is more complicated with the Double Belt so be sure to consult SCHROTH or your dealer before purchasing. We offer a weld-on bracket to aid in the installation.

SCHROTH’s QuickFit asm® harness is the PERFECT harness for Drivers School, Autocross, or just bombing around the countryside. Try it on a long trip we promise you won’t get nearly as tired. The QuickFit harness offers all of the proven benefits of the SCHROTH Rallye series belts with the added benefit of easy installation and removal between events. QuickFit uses all available factory female recepticles with factory original buckles. Since we use the factory receptacles with our belt, we can take advantage of several safety systems active in the car. Each QuickFit belt is specific to a make and model of car and the belt must never be sold or transferred to another vehicle of a different make or model. QuickFit does not, in any way, effect the operation of your factory seat belt.- unlike all other “Street Legal” belts on the market today

QuickFit Pro
SCHROTH’s revolutionary Quick Fit Pro is the world’s first 4 point harness that is designed to be used with a HANS® Device in your stock seats! Now the safety and peace of mind that come from driving with a HANS® device is available to the Driver’s School and Open track day participant. By changing the geometry and adding a central Camlock, SCHROTH has designed a 4 point belt that adequately captures the HANS® device in an impact and allows it to function as it was intended. These harnesses are designed to be used in stock seats that have passed a seat back strength test. Now you don’t have to spend big money on a Rollcage, seats & harnesses just to benefit from the safety of a HANS® Device. You can also add an anti-sub strap to a QuickFit Pro if your seat has a provision for an anti-sub strap in the seat bottom. This will give you even greater anti-submarining protection in an impact.

2” Lap Belts
RFR™
DOT-FMVSS 209
Patented actuator (recessed lever). All standard racing harnesses come with this type RFR™ rotary buckle.
A 2” Lap belt shown on a replica of a human pelvis
A 3” Lap belt shown on the same pelvis
To explain why 2” webbing is more effective than 3” webbing, one needs to look at the shape of the human body. The Iliac Crest is the part of the pelvic bone that sticks out above the hips. 2” webbing fits entirely within that crest (see the red belt in the image above), where 3” webbing (blue belt in the image above) rides over the tips of the crest. The 3” webbing has less surface area by percentage than the 2” webbing which will cause more bruising on impact as “hot-spots” of force develop where the belt is making contact with the pelvic bone. Since the 2” webbing rides inside the crest it can be worn as much as 1” to 2” tighter and at the same time is more comfortable.
by using a different weave and/or thickness on 2” webbing compared to 3” webbing.
Since the 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 or elongation of the 2” webbing. All webbing (2” or 3”) must meet the same load tests and elongation standards. This is accomplished
42
2” lap belts have an additional advantage in that the adjusters are much easier to use, while being lighter and less obtrusive. There is much less likelihood of cording the webbing or getting the adjuster caught in the seat openings.
The patented SCHROTH RFR™ rotary (cam lock) buckle operates with a carbon fiber reinforced gear system. Since it operates grease free it is insensitive to dust and other environmental influences. RFR™ the abbreviation for Regressive Force Release, means the release force is reduced during release operation rather than increasing as seen with all other rotary buckle products. Therefore the RFR™ buckle meets the stringent FIA required release forces without the need of an extended lever. The patented actuator with the recessed lever helps to avoid the risk of accidental release. The durable RFR™ rotary buckle is approximately 30 percent lighter than other products, yet it is still one of the strongest in the market. For FIA and ECE-R 16.04 (street legal) approved racing harnesses (FE models for Rally driving) it is available as a push button type buckle.
SCHROTH street legal harness belts are unique in their ability to be installed to factory provided mounting points along with the factory provided seat belts. SCHROTH harness belts meet all certification requirements by the German TÜV, ECE-R 16.04 and US-DOT FMVSS 209 for use on public roads. Each belt comes with complete installation and operating instructions. If your vehicle is listed in the included Vehicle Reference List the installation has been tested and appoved with the stock seat or the listed aftermarket seats. SCHROTH QuickFit harnessbelts have the make and model of the applicable car printed on the tail strap label. Unlike most other aftermarket harness belts, most SCHROTH street legal harness belts have a unique disconnect feature between the front part of the harness and the rear tail strap. When you are not using the SCHROTH street legal harness belts, they can be stored out of the way allowing complete access for all passengers and full use of all factory seat belts.

NYLON®
With asm ®
The patented SCHROTH asm® system offers an unique safety advantage for 4-point harnesses. asm® is the acronym for anti submarining. The risk to submarine (sliding underneath the lap belt), a well known phenomenon during frontal impacts, is significantly reduced by the asm® safety system. The energy converter is located in the inboard shoulder belt. Therefore make sure you purchase left and/or right harnesses. Severe injuries or death are possible using 4-point harnesses without the SCHROTH asm® safety system or an anti-sub strap. SCHROTH harnesses designed for use on public roads (FE push button models) or those likely to be used as 4-points come with the asm® safety system. The performance of the SCHROTH asm® safety system has also been positively tested in conjunction with airbags.

Current Head And Neck Supports (HANS®) provide further reduction of head deceleration and neck bending. The asm® system on all SCHROTH Rallye and QuickFit belts - excluding the new QuickFit Pro - is not compatible the with HANS®. Only belts having a center RFR Cam lock can be used with HANS®. We recommend that only non asm® belts be used in competition harnessbelts. Racing harnesses without asm® must be worn with an anti-sub strap!

Figure 2: A points to the woven in mono filaments, responsible for the “memory effect”. B points to the round edges for additional comfort.
Webbing that makes the difference! The webbing we use is especially designed and manufactured for SCHROTH. Each lot manufactured must pass our 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.
Unique to SCHROTH is the “memory effect” we have designed into our 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).
Polyester also has a better force/elongation ratio so a well designed webbing can convert more energy during an accident.
8,000 Pound Webbing SCHROTH’s experience in NASCAR has yielded another technological breakthrough, a webbing with 8,000 pound tensile strength that retains the elongation and deceleration properties that our previous webbing delivered. All SFI 16.5 homologated restraints feature this new webbing, as well as any belt with “Zip” adjusters.

TECHNOLOGY
Hybrid™ Restraints
Engineering in Action! Typical Formula (D-Ring) restraints display high upper torso trajectory during a crash. To reduce this trajectory, the crotch straps have to be routed backwards and to be worn extremely tight. Some drivers complain of reduced blood flow in their legs. In addition, this configuration is not as effective in rear impacts at keeping the buckle and the lap belt in the correct position. In particular in typical open-wheel race car seating positions the driver is not kept firmly in his seat but is likely to move up exceeding the roll over protection bar. The so called T-bar 6-point belt design provides a better restraining function since the anti-sub straps can be routed downward and slightly rearward from the chest/crotch tangential. This keeps the buckle in place and provides direct load transfer from the shoulder straps into the anti-sub straps. During a rear impact the anti-sub straps keep the buckle and lap belt in place and restrain the driver much better in the seat. The disadvantage of a T-Bar style restraint is that some people complain that the anti-sub strap bracket rubs on the inside of their upper thigh. To increase comfort, the buckle is often not worn as

Flexi Belt™
low as it should be for best lap belt positioning. The design of the T-Bar also precludes the addition of a 7th point sub-strap.
Flexi-Belt™ - one harness, many variations!
The solution: the revolutionary SCHROTH Hybrid™ Restraint.
Length adjusters in lap belts come as “pull-ups“ or “pull-downs“. In addition they often have to be positioned differently to achieve optimal operation. SCHROTH has developed the solution which covers your different needs with just one lap belt model: the “Flexi-Belt™”.
The crotch straps are not routed through D-rings or attached to a T-Bar but are held directly by the specially developed lap belt latches.Thanks to the patented SCHROTH RFR™ rotary buckle the load tranfer from the shoulder belts through the buckle into the anti-sub straps and vice versa in case of a rear impact is achieved. This direct load transfer is important for optimal restraining performance.
The lap belt latches and brackets supplied with the harness can be assembled 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 optimize the adjuster position depending on your car, your seat and seating position. Even exchanging mounting hardware is possible (e.g. a bolt-in bracket for a snap-on bracket). “Flexi-Belt™“ is only available with 50 mm (2”) lap belts, SCHROTH “-II” models.

HANS Specific Shoulderbelts
“Zip” Adjusters
SCHROTH designed and developed the 2”/3” HANS® Specific shoulder belt configuration in 2002 when the HANS® was becoming the dominate head and neck restraint (“HNR”) in motorsports. It solved racers concerns about webbing hanging off the yolk of the HANS® and/ or getting caught up in the seat openings. The concept of the 2”/3” HANS® specific restraint is quite simple; SCHROTH designed a belt which fits cleanly and completely onto the surface of the HANS® without any extra webbing to hang off the side or running up the collar. The fitment of the 2” webbing on the HANS® allows for secure and optimal routing of the restraint. In the last few years new SFI 38.1 HNRs such as the Defender and Safety Solutions Hybrid and R3 devices have been released. These devices work similar to the HANS®, in that the shoulder belts of the restraint passes over the top of the device as the device sits on the shoulder. They also all share about a 2” width at this point. The HANS® Specific shoulderbelt design fits perfectly on the HANS® device.
Gone are the days of fighting to get the harness tight enough, or struggling to release yourself in the heat of competition. Our new 2” ZIP adjusters are the easiest and smoothest adjusters available anywhere. These adjusters are used exclusively in conjunction with SCHROTH’s 8,000lb webbing. The design virtually eliminates any “microslip” through the adjuster in an impact. ZIP adjusters are used on our Profi Enduro belts and all of our SFI 16.5 Cam Lock and Latch Link belts with 2” lap belts. The integrated “Zip” Adjusters give the industry’s easiest adjustment and release. Perfect for endurance racing.
Our 2”/3” design with the 2” webbing passing over the top of the HNR device is available on ALL of our 5-point and 6-point models, Profi, Hybrid, and Formula restraints. The 2”/3” HANS® Specific restraints are used in Formula 1, NASCAR, Porsche Cup Cars, WRC, IRL, WTCC, and virtually all other racing series. If you use, or are planning on using a HANS® or one of the other compatible HNRs, we recommend you select shoulder belts of this type. Look for the symbol throughout the catalog to pinpoint this shoulder belt option. Most sanctioning organizations require you to run an HNR when using the 2”/3” shoulder belt option.
