Anyone see a reason our cage won't pass tech? (Page 2 of 2)

Here's a bunch more words.

NASA:

3.6.2.5 Shoulder Harness
The shoulder harness shall be a two-strap over-the-shoulder
type. (“H” type configuration is permitted.) In the downwards
direction, the shoulder straps must be directed towards the rear
and must be installed in such a way that they do not make an
angle of more than 45 degrees to the horizontal from the upper
rim of the backrest, although it is recommended that this angle
should not exceed 10 degrees. The maximum angles in relation
to the centerline of the seat are 20 degrees divergent or
convergent. (See diagram 253-42) Anchorage points creating a
higher angle to the horizontal must not be used unless the seat
meets the requirements of the FIA standard. A safety harness
must not be installed on a seat having no head restraint or
having a backrest with integrated head restraint (no opening
between backrest and head restraint) (If the seat does not
provide lateral restraint, the mounting point on the vehicle
structure shall be a minimum of 20 inches behind the seat back
when measured along the belt.)

Rally America:
H. Shoulder Harness
1. The shoulder harness shall be a two strap over the shoulder type.
There shall be a single release common to the lap belt and shoulder
harness. Only completely separate straps are permitted. “Y-type”
shoulder straps are not allowed; “H-type” configuration is allowed.
The separate straps shall be individually attached to the structural
points of support. The shoulder harness angle to the point of support
shall be between horizontal and 10° below horizontal and
perpendicular to the rear of the seat. The belts shall also be kept as
short as practical. At the mounting point, the distance from the
center of one belt to the center of the other shall be 7" or less, closer
is better.

SCCA:
The shoulder harness shall be the over the shoulder type. There
shall be a single release common to the seat belt and shoulder
harness. When mounting belts and harnesses it is recommended
that they be kept as short as reasonably possible to minimize
stretch when loaded in an accident.
The shoulder harness shall be mounted behind the driver and
supported above a line drawn downward from the shoulder point
at an angle of 20 degrees with the horizontal. The seat itself, or
anything added only to the seat shall not be considered a suitable
guide. Guides must be a part of the roll cage or a part of the car
structure.
Only separate shoulder straps are permitted. (“Y” type shoulder
straps are not allowed.) “H” type configuration is allowed.

FIA:
ARTICLE 6 : SAFETY BELTS
6.1 Belts
Wearing of two shoulder straps and one lap strap ; anchorage
points on the shell: two for the lap strap, two or possibly one
symmetrical about the seat for the shoulder straps.
These belts must be homologated by the FIA and comply with FIA
standard n°8853/98 or 8854/98.
Furthermore, the belts used in circuit competitions must be
equipped with turnbuckle release systems.
On the other hand, it is recommended that for competitions which
include public road sections, the belts be equipped with push
button release systems.
The ASNs may homologate mounting points on the safety cage
when this cage is being homologated, on condition that they are
tested.
6.2 Installation
It is prohibited for the seat belts to be anchored to the seats or
their supports.
- A safety harness may be installed on the anchorage points of the
series car.
The recommended geometrical locations of the anchorage points
are shown in Drawing n° 253-61.

In the downwards direction, the shoulder straps must be directed
towards the rear and must be installed in such a way that they do
not make an angle of more than 45° to the horizontal from the
upper rim of the backrest, although it is recommended that this
angle should not exceed 10°.
The maximum angles in relation to the centre-line of the seat are
20° divergent or convergent.
If possible, the anchorage point originally mounted by the car
manufacturer on the C-pillar should be used.

Anchorage points creating a higher angle to the horizontal must
not be used unless the seat meets the requirements of the FIA
standard.
In that case, the shoulder straps of 4-point safety harnesses may
be installed on the rear seat lap strap anchorage points originally
mounted by the car manufacturer.
