Iva Seatbelt Upper Anchorage

[Guest mcramsay]

what part is classed as the upper anchorage? In the photo below would it be where the top mounting physically bolts to the chassis? Or where the belt runs through? Ignore the belt running through the plastic handle of the headrest, iva def won't like that! Currently I am around 20mm lower than the 450mm measurement for the upper seatbelt anchorage position.

 

Only way I can think of getting around it is to bolt the seat solidly to the floor without the runners, which will give around another 30mm drop

Top mount , I think would be the one by your shoulder ??

Yep as it stands the effective anchorage point is the clip on the seat. f the seat is from an OE application, it might well pass IVA

Knowing VOSA I reckon they would take where the seatbelt changes direction

coming out of the movable triangle.

Otherwise you could have a mount a foot long & the belt coming out under your arm!!

So I spoke to the manufacturer today. And my car is a prototype and has had a redesign of the seatbelt mounts so the mount position was something they over looked, but they are going to have my car back once I have finished building and put a mount point further up on the roll bar so I am well clear of the 450mm minimum measurement. I think they plan on drilling a hole through the roll bar and then sleeve it to keep the strength. Can't really see another way around it, I've dropped the seal as low as it will go and I'm still under!

I had the same belts when I went for IVA and the "the triangle" part I mounted halfway up the roll bar so it was above shoulder level. Passed ok. May have to check IVA manual?

The actual bests are iva proof, it's the mountings on the chassis that are causing the issue

Bear in mind it's 450mm + 53mm of the block on the seat so at least 503mm + any seat pad angle
