Ouch! This is why we all need HANS

[rallycross]

Saw this clip today shows how much impact the body can get from even a fairly low speed bump

Something looks off in that clip, almost as if his belts werent tight enough.

Either that or they stretched a whole lot/ something broke

That Simpson Hybrid harness doesn’t look like it has been properly put on, nor do the straps look to have been correctly adjusted.

I don't understand - drivers notes are that the overturned cone caused the crash, but it it looks to me like he'd already braked late and gone too wide on the corner - he was going through the cones regardless?

[JeremyH5]

Braked late, missed the left entry apex by the width of the track, ripped front wing off on right hand kerb and cones, understeered to the point of impact. And hadn’t correctly adjusted the HANS device he bought at great expense.

Yes, he was clearly going to crash regardless. The cone under the wing might have contributed slightly to the impact speed through diminishing braking effort, but I think it’s marginal.

Taking to the escape road would’ve been the far better option.

Belts seem not tight to me.

To be fair on that lad it is amazing how far the body moves and extends in a shunt like that. Many moons ago I did a single venue stage rally at Oulton Park in my MG midget. I smacked head on into a tyre stack placed in the middle of Cascades going round the circuit in the wrong direction, dhead. The car was fairly well battered, me and the navigator were OK but a bit winded. I didn’t think anything of it until we popped up on a very early Havoc crash video. In the video you can clearly see my navigators head actually hits the dashboard in front of him. Which is bloody amazing given we were both well strapped in with harnesses. No HANS in those days .
We tried it static and strapped in and you really wouldn’t believe it was possible to headbutt the dash. Didn’t knock any sense into him mind you.

Something definitely off there. I've had a crash similar to that with a normal HANS and nearly twice the speed and not even remotely the same level of head movement. People who use the Simpson version are always telling me they are superior so I'm assuming that one wasn't fitted properly.

By the looks of it hes only got 4 point harnesses, so likely hes slid down in the belts which is why the belt looked to be loose.
coupled with a Hans that hasnt been set up properly

Hadnt noticed that, but looks to be the case from the video

Incredible anyone would run without a crutch strap in a single seater

Graham is a front runner competing in the British Sprint Championship. As an MSA governed event a minimum 5-point FIA approved harness is required for racing cars.

Should the thread title be amended to "Ouch! This is why we all need to learn how to use HANS"?

As well he may be but it still looks like he went flat out on cold tyres.

He essentially understeers into the cones. 0:32 in the video.

Hopefully he’s mended okay, looks very painful after intial adrenaline wears off.

[ecsrobin]

Just watched it,can’t believe he didn’t cut the corner and go straight on. Was very obvious he was never making that.

About 20 years ago friend had an off there in Dallara F3 , not using chicane and we did 43 sec laps , flat the whole way baring the chicane . He hit that tyre wall as such speed the car broke into 2 and the monocoque flew over me onto the inside of the track ..... he retired after that

I can tell you’re not familiar with sprints and hills climbing.

Timing is done from a standing start and normally over no more than 1 to 1.5 laps of a circuit. Tyre warming or any spinning of wheels before the start line is not allowed.

Most cars will run high downforce and super soft tyres so they get up to temperature within a short distance.

No I am not familiar but always happy to be educated.

Both my son and I both do Speed Events, and both use simpsons, the positioning on the shoulders is virtually the same as the HANS, and so is the positioning of the belts.

it is essential that whichever FHR is used it is positioned correctly so it sits down onto the shoulders, with harness over the top pulling downwards, and both the forward and side straps correctly adjusted.

We are only in a Caterham, but what we have found is that with the Belts & FHR correctly adjusted you can't move your body upwards or forwards and whilst you can turn your head you should have minimal forward & backwards head movement, and minimal side to side movement.

The difference between a standard FHR & the Simpson Hybrid is side impact protection, but as always regardless of type of FHR or any belts they only work if fitted & adjusted correctly. We probably have the strap lengths more towards the minimum recommended movement for side tethers is 1/4", and between 1/2" and 2" for forward movement.

I know after seeing this video we will be double checking what length the Simpson to Helmet straps are adjusted to before this weekends event.
