Triton seat - harness - mounting point question
Hi there.
I recently have installed my seats, and now I want to fabricate the upper harness mounts.
Do I need to raise the mounting points to clear the seat hole edge? Or should I make the hole bigger  ?? When I sit in the seats, the harness will
point upwards and it clears the seat.
 
Harness q
When a a small person (say my wife) sits in the seat, it will not clear the seat.
 
Harness q2
 
Harness q3
The mounting points are 450 mm above the reference point.
The reason for asking: AFAIK the mounting poins can be an easier construction when not raised.

I think the mounting points need to be higher than the holes in your seats.

I think the idea is that if you have a crash with the seatbelts at the height they are, as the mounting point is lower than the top of your shoulders,
they will crush your spine as you are thrown forwards!

Is there an optimum angle for mounting the harness? (I have TRW harnesses.)

No need to open up the holes matey, if you do you lose the rolled edge.
My Daughter has taken over production of the damn fine Triton race seats and her contact email is emmatrs@live.co.uk.

Slightly OT, but I have a bracing bar running diagonally across the roll bar (see pic). I am fitting some f/g seats with harness holes which are some
way above the current harness mounting points.
Instead of using the existing mounting points, would it be better to loop the harness straps over the diagonal bar? It means a) one side would be
lower than the other, and b) at least one of the straps would be angled downwards from the mounting point to the harness hole, but it would avoid the
problem mentioned above in the event of a crash, i.e. the strap crushing down on my shoulders.
Thoughts?

Isn't this what the 450 mm is for?

Please define 'some way'?
I would at least try to have all the mounting points at the same height.

I do not think that this is acceptable as I am sure somebody posted on here within the last week that this was one of the fail points during their SVA
