Hi all,

Quick question regarding seats....

Currently building a sylva j15, and was thrilled tonight when my new seat arrived and it fitted. It's a seat that I used in my Westfield and knew it was the right one for me, so as very happy when it fitted.......

Anyway, a quick read of section 15 of the iva manual, and the alarm bells started to ring...if you clearly do not have any room behind he seat, do you still need to worry about the edges facing rearwards.

Anyone have any issues with carbon / fibreglass seat going through iva?

section 12 (interior fittings) is the one you want to be reading
if you can't get at it with a 165mm sphere, then it can't be tested. if there's no room behind the seat, then should be just fine

I too am building a J5 but with GRP seats from an MK source as I have them currently fitted in my Westfield and I like them so much I fitted same in J15 (nothing exciting so far). I fitted them close to the floor as possible and had trouble with the steering wheel position/attitude being a bit high (so I lowered it). The handbrake cable fouled the passenger seat mountings (now runs under the floor). The passenger seat also fouls one if the seat belt anchorages (not solved that one yet). Hope you have better luck than me.

I am going to line the edges of my seat + seat belt ports with a plastic U channel.

The push on U trim or glued on rubber U trim will make it IVA compliant

There seems to be a rule that they can go in 300mm from the exterior of the car with a 100mm ball to get at stuff, and at my iva last week the tester said they treat the boot area/behind the seats as the exterior on cars without a roof.

Just buy some of that CBS stuff with the non setting glue in it, it can be removed with no damage or scratches and the glue isn't that sticky. Just put it on the bits contactable with a 100mm sphere.

I had the rear of my seats checked at the IVA (Manchester / Chadderton) Any part the sphere contacted from the outside. He described it as "what if a cyclist goes into the back / side of your car!". Then he used a diff sphere to check the edges the driver / passenger would be exposed too.

So I'm now Government approved to reverse into a cyclist.

Thanks for replies........I need to get the body work on, as I think when this is on, no part of the rear of the seat would be exposed.
