Engineering certificate for seats

This is what I thought Mudguard.....but I have heard a mixture of information... Even a recaro distributor said " technically they should be certified by an engineer" if they are non factory item. I particularly don't want the added cost but wonder what would happen if I had a bad accident and hurt someone...

Some good reading there Peter D, thanks ,,,I can see Mudguards point... About ADR rules... A little confusing. And can be interpreted many ways ... Obviously most engineers will say they have to be certified as it's money in their pocket. I guess a phone call to the RTA technical line is a sure way to be certain... Thanks again

That's right if its a straight bolt on affair ok but if its integrated into the vehicles safety system you'll need that piece of paper.

Any changes to seating require an engineers certificate regardless of whether airbags are involved or not.
I've fitted aftermarket seats to a half a dozen vehicles over the years and all have required certification. Recaro will probably already have certification/compliance for some models if they have supplied them for OEM use.
As you are probably aware the seat and frames on a Recaro are probably ten times stronger than a standard Toyota seat, had a friend have a big prang in his troopy with Recaro's fitted and the seats stayed intact but the Toyota mounts peeled out of the floor.
