Hmmm, my downloaded copy of the manual does not have a section 31, the only section it has that has anything to do with seatbelts is section 19 and it has no picture or mention of a reference point. Starting to think I have a dodgy download, will get another from the Vosa site.
The only diagram I have of the seat shows the headrest height at 753mm above the seat squab.
Thanks for the replies chaps.

Just downloaded a new copy, it is indeed 450 above reference point. There is no requirement for distance between upper fixings but there is for lower fixings which have to be between 350 and 500mm apart. My upper fixings will be about 75-100mm above the minimum so I should be fine. Happy days

Glad I am not the only one !!

I thought I was going off my trolley, Knowing I had read that section & then unable to find it again for another read

Probably reading an online version at the time, meethinks it best that I download a new copy as well

My memory was 50mm out .... That's about parr for the course with me .... My mental tape measure needs replacing

Hi, before you weld anything!
there is a dimension for width of the top mount from the centreline of the seat.
not sure if it only applies to a lap/diagonal belt or includes harnesses too
gonna have a quick scan of the regs now

Hi, section 31 page 2 no. 17
"A Lap/diagonal belt "effective upper anchorage" location must be at least 140mm from the longitudinal centre line of the seat (see note 14)."
knew id seen something somewhere.
I read it as only applying to normal seat belts and not harnesses but ive spaced mine accordingly as i may use some ordinary belts or harnesses.
so ive put in two top mounts per side and may put an extra one near the floor below the top mount so i can use an inertia real belt as i find harnesses a pain to use
anyway there it is
hope it helps
Ray

Hi Ray, that is for a "normal" seat belt with a diagonal strap that goes from (on driver's side) right shoulder to left hip, harnesses are not diagonal belts. I was quite surprised that there was not a requirement for spacing of upper mounts when there is one for lower mounts. I guess I will just do mine so they are comfortable. Thanks for your responses and for taking the time to look it up.

The main thing he will check Dave is the the upper mounts are not lower than your shoulders so that they do not go up from the mounts to pass over your shoulders. They need to be level or above your shoulders. The strength of the brackets and bolts, plus that when your belts are tight you can release the catch and comfortably remove your arms / shoulders from the belt without slackening them off, he will try this himself a few times. Stick with the industry standard 7/16 unf 8.8 grade bolts and nuts (should be marked on the bolt) just to be sure.

Maybe we'll get another first time pass.......

Regards...AndyH
