Wearing your Racing Harness safe

1. General Instructions

To help reduce the risk of serious injury in an accident:

·     Never use the harness belt system for persons which weigh less than 40 kg (88 lbs.) or those who are less than 150 cm (4‘11“) tall, regardless of age.

·     Never strap more than one person in place with each harness belt.

·     Never use the lap belt portion of the harness belt without the shoulder belts and the anti-submarining strap (if a 5- or 6 point belt is installed).

·     All straps must permanently run through the slots of the bucket seat – as shown in the figure below.

·     Always make sure that no strap is twisted when worn.

·     Always wear the lap belt portion of the harness system low and tight across the pelvis.

·     Pressure of shoulder belts on your shoulder and chest must be equal.

·     Never wear the belts over heavy clothing as it can interfere with proper positioning and adjustment of the belts, reducing the overall effectiveness of the system.

·     Never wear the belts over rigid or breakable objects in or on your clothing, such as eye glasses, pens, jewellery, keys etc. as these may cause injury.

·     Never allow straps to rub against sharp objects.

·     Never allow the belts to be damaged by becoming caught in door or seat hardware.

2. How to operate tilt lock adjusters

SCHROTH racing harnesses utilise “tilt lock adjusters” for quick adjusting the harness belt.

To lengthen a strap, tilt (lift) the adjuster up to 90 degree relative to the strap and pull in direction as indicated. To tighten a strap, pull at the protruding strap end as indicated.
If tilt lock adjusters are equipped with a release strap, simply loosen the harness belt by pulling on the strap to lift the adjuster.

3.  How to engage your Racing Harness

3.1 Profi  5- and 6-point models

·     Loosen the shoulder belts to allow for proper positioning of the lap belts and rotary buckle.

·     Engage lap belt and tighten securely. If the race car is equipped with a sliding seat track, it is recommend that the seat be slid rearwards by one or two detents. After tightening the lap belt, slide the seat forward again into the correct seating position.  This will optimally tighten the lap belt.

·     Make sure the rotary buckle is well centered to your body.

·     Engage now the anti sub strap in the downward pointing slot if it is not the fix point at the buckle. Make sure the T-bar ends of the anti-sub strap II point away from your body.
