2. H OW TO OPERATE TILT LOCK ADJUSTERS
TAKATA racing harnesses utilise “tilt lock adjusters” for quick adjustment of
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.
Make sure the adjusters are correctly positioned to avoid interference with the
seat or the wearer’s neck during normal use as well as during an accident. See
section of this manual titled “Initial Restraint Installation”.
Made to measure racing harnesses often do not have adjusters at lap belts
and/or anti-sub straps. If such a harness is used, make sure body tight length
is achieved during initial installation. If necessary re-adjust the strap lengths
at brackets.
Follow instructions in section “Wrap Installations”.
with an Head And Neck Support
Make sure the shoulder harness is properly positioned on your Head And Neck
Support if worn. Adjuster must be on lower tip of the Head And Neck Support
yoke.
Interference between an adjuster and the seat or the collar of a
Head And Neck Support during an accident may release webbing
through the adjuster or “dump” webbing into one edge of the
adjuster. As a result, webbing may be cut and fail. Severe injuries
or death may occur.

• Loosen the shoulder belts to allow for proper positioning of the lap belts and

seat track, it is recommended 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.
