Hi there. can anyone help advise on IVA position with regard to full harness seat belts. I have bought some seats off ebay which have harness slots. as i am led to believe when you are in the seat with the straps fitted the belt is not supposed to stress the seat but hold the body across the shoulders. when i am sat in the seat the slots are higher than my shoulders and the harness would be tight on the seat. I have gone through the IVA but cant find a specific note on this unless there is a newer version out.

thanks
simon
