Shoulder spacing belt wrapping, Other information, Installation checklist

The following formula is used to determine the spacing of the
shoulder belts at their attachment to the harnessbar or cage.
Formula: Y = Z - (X * 0.50)
X = Distance from Shoulder Points to attachment. Measure from the
highest shoulder point (on top of the HANS® if warn)
Z = Distance mid to mid of webbing at shoulder point
Y = Approximate distance between anchor points. (measured mid to
mid of webbing at anchor point)
The shoulder belts will cross over when anchor points are
located more than 450 mm (18”) behind the seat back rest.
We recommend a distance of 8” or less from the back of the
HANS to the harnessbar when possible.
SHOULDER SPACING
BELT WRAPPING
LV4, LV17 Lightweight Wrap
1) Place LV 4 with its thicker bar onto the bracket/latch.
2) Run strap end through slot at LV 4 and then from under-
neath through webbing slot at bracket/latch. Pull through
at least 200 mm (8”) of webbing. Fold strap end over the
wider bar of LV 4 and back through the gap bet-ween
bracket/latch bar and LV 4 bar.
3) Slide strap end further through the webbing slot at
bracket/latch and then fold the strap end through the slot
at LV 4.
4) Pull at the load taking strap and the bracket/latch to
make sure, the webbing is properly clamped by the wrap
hardware.
B40, B63 Integrated 3-Bar Adjuster Bolt-in Brackets
1) Webbing should wrap from the body facing side of bracket up
into slot 1
2) Pull through approx. 270 Mm (11”) and fold down through slot 3
temporarily leaving 50 mm (2”) of slack.
3) Fold back up from the body side through slot 1 and back down
through slot 2
4) Fold back through slot 3 and fi nally through slot 1
5) Pull the lap belt fi rmly to ensure the wrap is properly tight.
OTHER INFORMATION
High density padding is used around cage where head could
potentaily come in contact. Padding should be either SFI 45.1 or
FIA Type A. Flat surfaces should use SFI 45.2 Sheet Padding.
Zip ties are used around all rollbar padding to keep it in place
Headrest padding - if used - should meet SFI 45.2 standards.
(Very high density. Soft padding will allow the head to bounce
off the headrest increasing head and neck tensions.)
All webbing and hardware is in good condition. No signs of
damage, cuts, fading, elongation, etc. Must be within date spec
for competition use (SFI 2 years from manufacturing. FIA within
5 yrs). Schroth Rallye series belts do not have an expiration
date. We recommend changing them every 7-10 years or sooner
depending on the condition of the webbing.
