Kimi in Monza 2007 went really far forward as well.mpbx3003 wrote:I'm really starting to think there was a failure of some sort with the HANS device. How many big straight-on crashes have there been in the past few years? Ralf at Indy, Kubica at Canada, just to name two. This is the only one I've seen where the drivers head goes forward violently. It might be that the initial spring hit jerked the yoke loose, but maybe Felipe had loose belts or some other improper use. I just hope this isn't the end of his career, though he'll probably be done for the season.
From what I can see because it happens so quickly, he hits the tyre barrier, the steering wheel turns hard right and he hits the left corner of it with the left side of his helmetzx9rc1 wrote:I think he hit the steering wheel too but like in Mikas crash it happened very quicklympbx3003 wrote:Did it?

I don't think you can really compare those two crashes, Massa's head doesn't look restrained at all. You can see the bottom edge on the back of Massa's helmet, but Kimi's head only goes far enough to see halfway down the back. That said, Kimi's head does go further than usual. Maybe Ferrari have some problem with the device.Ray wrote:Kimi in Monza 2007 went really far forward as well.
The car has gone across the grass some distance, so the tyres have picked up loads of debris so are only working at probably 30% of normal grip, the car would be light coming down off the kerb after the grass and also the run off area would compound the issue by being dirty, add in the fact the fronts were probably locked but the rears may have still had enough drive on full throttle to just plough the car straight on and overcome the brake force to some extent. Which is maybe why they were locked up all that distance. Hard on the brakes but no effective retardation as you would normally getRay wrote:I watched one video and you could see right at the time of impact the G meter on the right increased by .2! That's amazing. But I think the telemetry may be wrong on the brakes being applied, but how else can you explain the wheels being locked up from the grass to the tires? He had to be somewhat awake.

I think the NHRA do. But their version of the HANS device goes to the small of the back and is clipped in around the midsection as well. I know WoO strap the arms to the center buckle to keep drivers arms from flailing around as well.n smikle wrote:Which other motor sport do they strap the helmet to the car again?
Nascar or NHRA?
Looking at the video again at about 8 secs, I dont event think the car is touching the ground after it comes off the kerb until at least 70% across the trackRay wrote:Good pointzx9rc1 wrote:The car has gone across the grass some distance, so the tyres have picked up loads of debris so are only working at probably 30% of normal grip, the car would be light coming down off the kerb after the grass and also the run off area would compound the issue by being dirty, add in the fact the fronts were probably locked but the rears may have still had enough drive on full throttle to just plough the car straight on and overcome the brake force to some extent.

I agree with this, even before he hits the barrier his head is bobbing about all over the show, When you have Hans on its not that loose from when I have worn it, only in impact do the belts and straps stretch, they do loosen off but usually in qualifying you arent out long enough to need to readjust them. Your belts should be done up so tight it hurts to some extent and its difficult to breathe to start with. You can move your head side to side but not backwards and fowards that easily.mpbx3003 wrote:I don't think you can really compare those two crashes, Massa's head doesn't look restrained at all.

I've never worn HANS myself, so can you answer a question? How easily can you remove the tethers? I was thinking that maybe the spring, when it bounced around after hitting him, might have knocked one of them loose.zx9rc1 wrote:I agree with this, even before he hits the barrier his head is bobbing about all over the show, When you have Hans on its not that loose from when I have worn it, only in impact do the belts and straps stretch, they do loosen off but usually in qualifying you arent out long enough to need to readjust them.
