how do you actaully work out the radius of a corner. example, 19mm radius edge on the lower edge of a dashboard.

could somebody draw me a picture on ms paint or something to show how to measure the 19mm?

cheers

Easy peasy ....

Just double the radius to get the diameter - 19mm radius = 38mm dia.
Imagine a slit 40mm dia tube slipped over the lower edge and you're safe from Mr SVA's probing clipboard.

ah, nice one! dead easy! cheers fella!

Thats exactly how I passed. Went to the DIY shop, bought some 40mm plastic pipe. Spilt it along it's length, and hot glued it to the bottom of the dash. Doesn't look pretty, but tends to fall of quite quickly!!!!

A bit like kneecaps that hit an unprotected dash lower edge in an accident!

I'm not suggesting we should expect our sevens to be as safe as a modern production car, but the SVA requirements haven't just been plucked out of thin air for amusement They're based on the fact the people involved in accidents in the 60s-80s ended up with some horrific injuries which could have been entirely prevented with good engineering.

We've all changed things after the test which make our cars less safe, I'm just asking people to think carefully about why the requirement is there before making post-SVA modifications. For example, with full harnesses having projections on the dash is not much of a concern. However, your legs are no better restrained in an accident and so it is highly likely your knees will contact the dash. Sharp edge of metal or smooth radius - take your pick

I saw a program once about bad car design- they talked about the Ford Flambee or whatever it was where the fuel tank was basically the rear bumper....

They also showed a car where the glove compartment was very flexible thin metal with sharp edges. In an accident the glove compartment would flex, unlock itself and open all in the time it took for an unrestrained body to fly forwards and decapitate itself on the sharp metal edge
