Revolutionary or ridiculous?

The flat head screwdriver needed by paramedics unsettles me a little...

Is doing the strap up on a helmet a problem?

Posted: **Sat Jul 23, 2022 10:34 am**

There was one available years ago, late 70s / early 80s. It never caught on (pun intended)

Could save 3 seconds of your life every time,brother.

I like the idea of my helmet being one whole piece - less to go wrong - less bits to pick up if goes tits-up. You can't expect paramedics to know how to undo one of those. I was told that they don't know what the red straps are for pulling out cheek pads so how would they know how to remove one of these? It's solving a problem that doesn't exist.

If jaw holds it in, it's gonna get broken. Ouch

Its not the lack of strap which is supposed to be important, its the fact it 'opens' rather than gets pulled down onto your head.

I can see that being better for removal after an accident, but id have thought having a helmet with a split down the middle is worse?

Mate had a GPA strapless helmet back in 1986, bought in France after his helmet got nicked (it was attached to his Tenere). The shell was one piece but there were interlocking "C" shaped lowers hinged back and front. https://www.ducatiforum.co.uk/threads/g ... met.77133/

He was involved in a crash when a car turned right in front of him and his helmet came off. Coroner blamed the helmet style/fastening for his death.

Tony Carter, ex-traffic cop, subsequently an accident investigator and occasionally on Visordown, did some work around this and found the it's possible for correctly sized and strap done up helmets to come off in crashes.

It happened me. In the 70s I was wearing a proper fitting Premier helmet when I offed around 120. As soon as my head hit the ground my lid came off. I remember it so well because everything was suddenly louder. How fortunate I was to survive cannot be calculated.

The thought of anything snapping locked on my canister feels me full of claustrophobic nervousness and ever building panic! So its a no from me even if they were free!

That's the gimp suit out then?

I was chatting to various paramedics and ambulance techs yesterday and they all said it sounded much better than the current system, at least in terms of getting helmet off an injured rider.

I can understand that in theory,but I have to wonder if differing types of lid and their removal methods are widely known among paramedics?

DD ring buckle is probably most obvious, with seatbelt buttons next. But the variety of flip'front helmets won't help.

Didn’t Simoncelli’s helmet come off in his crash with Rossi? Mount failed iirc?

Don't know.

In ye olden days, some strap fixings were too far forward. A simple test was to put helmet on and comfortably tighten the strap.

Then thumb under strap, pull forward while pushing hard on the back of the helmet to compress the lining.

Some straps would go over the chin

I'll ask them in more detail the next time I can. I suspect it will vary massively depending on the prevalent type of incident they deal with. Sadly the ones in the Scottish Highlands will likely have more experience.

What Tony found (I know he talked with manufacturers) was that it's possible for skull bones to flex/move enough to increase that strap movement.

His interest was via an insurance injury claim.

Other end of the scale. In the Thames Valley, in the early 1990s, there were several fatals where helmets came of because they weren't done up.
