Helmet fastenings: Double D-ring Vs Seat-belt type

Whats your preference?

I've never had anything but the seat-belt type fastening on my crash helmets, but the new lid I bought today comes with the double d-ring. And as I stood in the shop fumbling with these arcane bits of metal I couldn't help thinking why anyone would prefer this method to the speed and convenience of the seat-belt ones. D-rings just seem to be an unnecessary pain in the arse; I even had to get the shop bloke to show me how you do it after my initial attempts failed. And to add insult to injury when I finally got it done it proved even more fiddly to undo again.

Obviously after a bit of practice it won't be a problem (hopefully) but it does seem strange that this method of fastening is still chosen by manufacturers over the speedy 'clunk-click-iness' of the seat belts.

Do the d-rings have inherent advantages over the seat-belts? Is one method more secure than the other? Or does one of the Directors of Arai own a D-ring factory on the sly, and is just protecting his investment?... Hmmmm

I'll have seatbelt type always fank you.Double-D is much cheaper.

I have a 'seatbelt' type as well on my Shark.I like it very much, my mate has a Haydon Shoei with a D ring, not sure about them.....

Double D has some advantages...every time you fasten it you make sure it is tight. The fastening mechanism does not wear like a seatbelt type could.It is fiddly to start with, but soon gets very easy. Double D every time for me if I had a choice.

Mine's got D-rings and it's a piece of piss apart from when the ends of my fingers are numb after riding in cold temperatures - even then I've got so used to it that it isn't a problem.I think they're better in that the seatbelt ones have more bits to break/give way. D-rings are simple and work well.

I always go for double d-ring.I can use them with my gloves on and the strap is adjusted properly everytime I put the helmet on.Also I never actually undo the strap fully when I take the lid off, so it is less fiddly than a seatbelt type would be.It's just what I'm used to, personal preference.

My first lid was the "seatbelt" type and I hated the "double D" type but since then I've had 2 "double D" fastening lids and prefer it to the "seatbelt" type. just can't make my mind up

The correct answer is, seatbelt is best.

Double D all the time for me. feels more secure.Don't like the idea of "seatbelt" fastener types, just think that if you spill then there is a chance it would get pressed against the leathers and open itself.

Good answer, but wrong.

I can't agree with Mr Soap, so I am now a convert to the new DD following.

Double D every time.Piece of piss once ya get used to it, less chance of breaking and perfect tightness every time..

where' the quotes? links? proof? etc

I've always worn Bell or Arai so have become very used to D rings, but I do remember some reports of early seat-belt fasteners coming adrift in accidents. Flip side is they are much easier for non-biker good samaritans to undo in an emergency.

I don't mind either. It certainly doesn't dictate my choice of crash helmet. The seat belt clips are more fiddly to adjust, but easier to do up, is all.

ahh yes.. that makes sense about being perfectly tightened every time, never thought about it much with my old belt type lids, never re-checked the tightness since the original setting of them when bought... suppose in hindsight I should have every now and again bit of an out of sight, out of mind sorta thing.....on another note, I just read the instructions for the new helmet and there is absolutely no information as to how you avoid knotting your beard into the D-rings along with the strap.... guess it going to be trial and error then..ooo ouch yipe ouch..

I think that Victor Kiam had advice on that one! Ab

The double d ring type dont work loose like the seat belt type do which is why only double d type helmets are the only ones allowed for most classes of racing.

Seatbelt ones can come undone unintentionally, double D ones can't. Seatbelt type ones are totally unnecessary technology, a "solution" to a non-existent problem which is just a gimmick and not as good as the simpler thing it replaced. This evidence suggests that they were invented by Honda.

Double D all the time.Had a seatbelt type once and it kept getting caught on either beard, neckwarmer and skin.Bloody hated the thing.Never could get the right tightness on it either.

38DD yes please but seriously my old helmet had double d fastening and my new shoei has seat-belt type and i prefered the double D as as mentioned before you tighten it every time you put it on.:smoke:

I like the "seatbelt" type.If a lid aint got one i wont buy it

christ, i agree with you twice in one night i knew i was feeling ill

I think you get used to whichever type you happen to be using.Personally I find the seatbelt ones easier to fasten but very difficult to adjust, but Double D are easier to open with cold fingers and easier to adjust to a comfortable tight fit. But I wouldn't shun any particular lid because of a fastening style.

I agree with the voice of reason. I own both types, I prefer the DD type cos they don't work loose. I have to ajust my Roof lid every time I put it on, which is a bit of a pain, (its the seatbelt type) but it's not that much bother in the grand scheme of things. You need to consider the other aspects of lid ownership, (such as the awful visor swap arrangement of the Arai for example).

..eeeep... ...t'was an Arai I bought today... you got me worried now...

Either/OrDouble D's are wank in winter though, if you ride then. Complete pain in the arris to undo with cold fingers

To my way of thinking, that is a pro for D-Rings. In my last off, with a closed head injury, it would have been much worse if a layman had removed my helmet.HTH

DD all the way for simply secure reasons. i dont like the idea that a seat belt might break in the mechanism or summat. if a button comes off a DD its still secure largely. at least long enuff for you to notice.

I have used both types but I much prefer DD type. If buying a new helmet I would only get it if it had DD fastenings. I dont feel safe and secure wearing a lid with the seatbelt fastening, i get too paranoid about it coming off cause I can never seem to get it tight enough.DD fastening are easy once you get used to em

Always had the seat belt version TA...my new ROOF has this also...Tried the double D thingy, wot a pickle I got into...really I ask you...fumbling all over the place...nearly fell over trying

Anything which contains the phrase 'Double-D' has to be a good thing

Much prefer the security of a double D, even if it's only perceived.

Got both at present (Vemar and Arai)I think they're as secure as each other, but I prefer the DD arrangement because it's simpler and gives a snug fit every time.The Seatbelt arrangement on the Vemar is a bugger to adjust and leaves far too much unused belt flapping around. Also I'm never sure if it's "clicked" into place properly.

I've had both types, and currently have a seatbelt type. I prefer the DD, as the seatbelt is quite bulky, and catches on my jacket fastening around the neck, which can be a bit of a pain. In the wrong circumstances, it can press against the throat a bit, which isn't comfortable.

Don't think this is true, is it? Anyone care to confirm? No shortage of Gold ACU rated lids with SB type fastenings

First helmet SHOEI RXR had a seat beltSecond lid SHOEI Interceptor had a Double D.I must admit I was a bit annoyed having gone from the bottom of the SHOEI range to near the top only to find an 'inferior' mechanism. However....The Seat belt is not easier to do than the Double D and the Double D is always properly adjusted and less likely to come undone.There is always a risk of the spring going in the seat belt style (as did on my wife's NOVAK) or it not being properly clicked in which occasionally occured on the first SHOEI.There are probably less quality checks required for the DD

Seat belt fastenings are for fat, lazy, ignorant, and clumsy people.

To answer Dodgy's questionRace regs require DD - I got this from SHOEI's FAQ.Why is Shoei using different chin strap locks?Our helmets are either equipped with our One-Touch-Buckle or the Double-D-Ring.Neither of them is safer than the other. For our comfort oriented models we prefer the One-Touch-Buckle. Once you have adjusted this kind of chin strap lock you can open and close it very easily. Our sport orientated models come with the Double-D-Ring. The reason is simply that Grand Prix Racers are forced to wear that system during the races and these helmet models have their origin on the racetrack.

i have 2 lids, one has the double D and one has the sb type. I prefer the lid with the SB, but i always wear the lid with the Double D, it feels more secure, i can fasten it snugly & secure, the SB type lid never seems to be tight enough, and doesnt feel secure, which is a shame cos its a nice lid..Id go for Double D every time with a lid now

Sorry, but this is simply wrong. ACU regs just say the helmet has to be Gold Approved and if the FIM had other requirements the ACU would cascade them down as it has with chainguards, undertrays, etc.As I said before my AGV is Gold Approved and it is a Seatbelt type.

I refer to my earlier post

Never found this a problem myself. Takes a while to get used to the horrible 'oh shit I've broken it' noise but once your past that the visors are a piece of piss to change, even when wearing the helmet.As to the original question I prefer double D for the reason that its tightened properly each time.

Like I said I got this from SHOEI's website.http://www.shoei-europe.com/en/faq.php#hNot saying they are right or wrong, but I would have thought it's more likely to be correct?A quick search of google revealed quite a few international clubs and race rules do not allow them..
