Rollover Bar & SVA
Discussion
My rollover bar sits just behind my head.
Do I need to cover any of it?
The bar is round and does not have any sharp edges so I think its OK, but I only need to jerk my head to sustain some damage. Ive seen a few cars with a padded head rest on the bars,is this just for comfort or a requirement?
Thanks

There isn’t any SVA requirement, but if you’re concerned about damage to the roll bar – I’d suggest you wear a padded flying helmet

Best let us know which station it was too, never heard of such a requirement myself.

edited to say: just read your profile so I guess it was Soton, the rumours must be true then: that they don't like kit cars at Soton SVA station.

Yes, I've heard horror stories about Southampton too! Have a look on your fail sheet and see what section it has failed on. Was it Section 15 "General Design and Construction" by any chance? This is a very vague section which seems to give the testers quite wide-ranging powers to fail a car on anything they don't particularly like but can't find a reason to fail elsewhere in the test. That said, it would - as the previous poster said, be like getting hit with a baseball bat. They don't have any sharp edges but you still wouldn't like to hit one hard with your head! The rally boys tend to pad their roll cages with foam pipe lagging insulation from DIY shops secured with tie-wraps. It's cheap, easy to do and it works well.

Yep, section 15. I did say about the pipe lagging - but no.
It is perishable, so I cant use it.
This was not flagged up on the day of test and passed that section, but was flagged up on the fail sheet the next day.
... but it's your head... I guess you need the roll bar fitted for your seat belt mountings, but if not could you just remove it for the SVA and then refit it with suitable padding afterwards?
Also, does this mean your head is level with or higher than the rollbar? In which case I'd want to get a taller one anyway.
Just ignore me if it's a cross brace rather than the top of the roll bar!

I've got quite a high loop on mine as I'm 6'3". It is the Diagonal, so only the drivers side has this problem.
I might have a chat to VOSA about the pipe lagging. I accept that it might well not be the best stuff to use from an energy absorption point of view but when you look at the other SVA areas that deal with energy absorption (e.g. dashboards etc) they talk about covering with a mateiral of hardness LESS THAN 50 (Shore "A") scale. They then go on to say that this is something that yields to thumb pressure (like a pencil eraser). That being the case, I think they might be going a bit OTT if they're moaning about it on the roll cage. If you had a sheet of the same material under the vinyl on your dash, they wouldn't give it a second thought!
