Hi all, kid way through a custom car build and I could do with some help regarding the correct (read IVA) way of mounting my 4 point harnesses.

The car is mid-engined, with a transaxle behind the engine. As a result, there is not a great deal of room between the back of the seats and the engine (or firewall, when it's built).

I designed the seat belts to loop over a horizontal bar running between the rool hoop uprights, and then for the harnesses to be mounted to the chassis close to the floor/ back of the seat. See the pictures.

My concern is that if I mount the belts beneath the horizontal bar that they loop over, they are very close to the motor. I can fab up a belt cover, but there is the alternator (not shown) on the passenger side that would probably be very close.

Other than this, I can mount the belts slightly forward of the horizontal bar, closer to the seat, see other pic. Would this be IVA ok?

Also, would you mount the eyelets for clip-on harnesses in direct tension or in sheer? I.e. To the side of the chassis rail or the top?

Many thanks

Steve

I was told it was acceptable to put the belt over the rail - Its the only way i could get the angle required to the rear of the seat with the engine where it is....

Any thoughts on whether the eyelets should be in sheer or in direct strain?

thanks guys,

I Thought IVA stated that the rear mounting point had to be 10 degrees below the eyelets on the seat?

I think i'll mount the belts to the top of the tube; just not sure which tube now!
