Seat belts IVA markings

Recommended Posts

I'm looking at getting some Willans 4x4 harnesses, the Willans site says  Harness approved to ECE Regulation No. 16 and the Demon Tweeks site says E approved.

The IVA manual says belts must be  BS3254 Part 1 1988 or FIA approved.

So does ECE and E2 supersede the British Standard?

Thanks

Ian

E2 simply means the origin of manufacture is France. 

Note though that what you have written is only part of the wording in the IVA manual.  The full paragarph is this (note the important bit in bold and underlined)

 

Each seat belt must bear the appropriate approval marks or have the equivalent characteristics to that of a belt approved for the same category of vehicle to ensure the belt meets the required approval standards. (see Notes 1 and 4

 

The belt does not have to be certified to BS3254, it can be certified to a different standard providing its construction is equivalent. Those Willans belts were standard fitment on Westfield factory cars for many years.

Hiya Guys

Thread resurrection lol So just to make sure & prevent me from making a purchase blunder, as long as a harness is FIA approved, it dosent have to be E marked (ECE)?

For example, would this one be okay:

Or is there any harnesses which you guys would recomend

Nothing wrong with OMP belts so far as I am aware, but beware; most 4 point harnesses (and the advert you have linked to would appear to be one) are configured to fit in a stripped out saloon, so they have long shoulder straps. You need short shoulder straps if they are going in a Westfield. If you look in the catalogues of the likes of Demon Tweeks etc., you will find that they also list harnesses specifically for Westfields, Caterhams etc. These will have short shoulder straps as they will be fixed to the chassis just behind your shoulder, not to the floor or rear bulkhead where the rear seat used to be (ie in a saloon).

Just to add, Luke Algar at Playskool Motorsport used to do a 4 point harness in 3" webbing at very reasonable cost. Don't know if he still does them, but worth asking.

Also note, on a Westfield, the normal way of fastening the harnesses In is with clip in shoulder straps, but bolt in lap straps, not clip in like those. There is very little room in the Westfield chassis either side of the seat for the harness mounts and bolt ins fit as they are very tight to the sides of the cockpit, where as those are much bulkier.

i believe you’re right on FIA homologation being acceptable, but be careful as whilst it may be acceptable in terms of replacing e marking, not all full harnesses have fittings that are particularly friendly, when it comes to other IVA requirements like edge radii, I honestly don’t know if they’re checked or not, but the buckles and adjusters on some have relatively sharp edges, which might just be a problem.

There have also been cases of “fake” harnesses being reported to the MSA and trading standards, (though thankfully, Westfield versions are probably specialised enough to escape the attentions of those particular predators), but none the less, I’d only buy from or recommend buying from, a trusted source/supplier.

Cheers Dave, been looking at the Schroth Westfield II ASM 4 point harness & have heard good things about Schroth.  Would this harness be okay for IVA.

I think pretty much any harness is OK for IVA - as the manual states (from memory) that they have to be "equivalent" to certain BS or FIA marked harnesses/belts.

The only thing to maybe watch out for is if they think any of the buckles might endanger the public by leaping out at them and poking them in the eye with a dangerous sharp edge or whatever!

EDIT: I have the Schroths you describe by the way and they are superb - but I did use a borrowed set or WF std buckle types for IVA prior to getting the Schroths

As I said previously watch race harnesses adjusters and buckles don’t get caught in the edge radii checks. I honestly don’t know the answer to that one. In fact, I’d suggest contacting your IVA centre to check. (You often end up speaking to your actual tester, and end up with extra brownie points before your test even begins!)

Ive got the Schroths too, after being recommended them by @Stuart Faulkner - Shows & Events Coordinator They are superb, but I IVA’d with a set of borrowed standard Westfield harnesses.

As Dave, I IVA’ed with a set of 4 point buckle harness to be sure I was ok.

I later sold them & it only ended up costing me £20 or £30 for piece of mind, you do still need to fit top hats to the rear fixings though.

- my other fear with the harnesses I’d intended to fit post IVA, was that they were 3” straps, which are a bit tight to get through Sport Turbo seats, and that the tester might raise objections, as the seat scrunches them up somewhat.
