Harness Strap mounting points
Hi,
Sorry to ask a (probably) silly question but my SVA book isnt here yet and Im eager!
Im planning to mount the top 2 straps of my 4 point harnesses not on the top chassis rail behind the seat, but on the bottom rail, down inside the
boot. Any ideas if this will be SVA ok? Assuming they arent rubbing on any sharp bits, of course.
Just I cant seem to find any pics of anyone else doing it!
Cheers,
Stu

Go to Hellfire's website, he has a 2005 SVA manual you can download.
Sure thing like that won't have changed much!

Thats only the draft manual AFAIK. Only includes the stuff that has changed/been updated. You may need to refer to that actual manual.
WRT your question, i see no reason why you cant do it. Most production cars with harnesses fitted attach them on the floor behind the seats...

It will depend on whether the upper pivot point of the belt will be the seat or your shoulders.
If it is the seat then you will need documentary evidence that the seat is strong enough.
If it is your shoulders then do you really want your spine acting as a shock absorber in a collision.
Ideally the top monts should be as high as possible.

The upper point must also be at the minimum height stated in the manual

The locost i have failed SVA on the top harness mounts not being high enough, according to the info i got the top mount has to be 450mm above the
front top edge of the distance piece(136mmX53mm) they place on your seat during the test, so would have to be roughly 500mm above the top of the seat
base.

AFAIK the harness can pass over a pivot point (same height or higher than the seat slots) and then go down to the mounting point

my concern would be having the mounting point and the harness really close to the road and therefore likely to get covered in lots of crud & crap.
Can't be good for the harness & how do you know if its fraying / deteriorating if you can't see it?

That could be said about mainstream production vehicles though!
The only way to be sure is to examine them frequently as should be done in an annual MOT!
The only likely places for them to fray is where they pass over the upper mount point and as they are not being constantly extended and shortened it
is unlikely. Also you should be able to see if this takes place.

I was worrying if the mounting point is the bottom of the chassis that road debris could hit and fray the harness.
