Time to bump this a bit.

There was a meeting between a group of engineers and the RTA on 19/07 to discuss the approval process, what was acceptable and also the dreaded VSCCS.

I had a quick chat to my engineer on Friday to discuss moving my approval process on again and it's fair to say he was pretty upbeat about what was discussed and agreed at the meeting.

Because I don't have more detail yet the summary of what they came up with seems to be something that is akin to where we were 2 1/2 years ago before the difficulties set in.

Because my chassis is a self build to my design things are slightly more complicated because I have had to have analysis done on the seatbelt anchor points and seat mounts ( modeled in FEA ).

It was an interesting exercise because whilst the seatbelt mounts would have passed a physical test they would have definitely deformed the mounting points on the tunnel by 8mm so not a fail but a major compromise of the safety if the test had been enforced.

FYI. The test indicates a pull of 1.3 Tonnes across the lap and sash for a defined period and in the interests of simplifying the test we applied 1.3T to each point individually so grossly exceeded the ADR, the deflection of the tunnel mounts was 8mm with a 1.3T pull.

We have done the same with the seat mounts and I expect to have the results in my inbox tomorrow. ( bastrad went to the snow for a week )
