 Poster: A snowHead
|
Alright, another question I'm putting out to you guys.
All ski bindings have DIN settings, but what I'm wondering (if you have already guessed from the title) Is how do the bindings know when to release you during a crash.
Is this some kind of ski hocus pocus.
Answers on the back of a small sealed envelope.
Cheers.

It's very clever like brake assist on a top end German car and can just sense when you're going to crash.....
the truth is somewhat more prosaic and basically relates to springs under tension (sorry)
Plenty of geek explanations along shortly

Well, the person's real but it's just a made up name, see?

It's the same magic used in thermos flasks. You put something in hot and it comes out hot. You put something in cold and it comes out cold. But how does it know?
It's basically a spring that is triggered by a certain force generated as a result of your weight and sole length (amongst other things).

The binding is a catch which is difficult to open because it is held in the closed position by a spring. Adjustment of the binding alters the force with which the spring holds the catch shut. When I fall, my weight acts against the spring to release the catch and thus my foot. The binding needs to have considerable resistance to opening because as I turn, the binding is subjected to some of the same forces as it experiences in a fall.

Perhaps DINs have characteristics in common with "Resublimated Thiotimoline".

Springs cams and leavers are all involved, I could tell you how it works in detail but the boredom would kill you

D G Orf, go on . . . and add the vector force mathematics to nail down the coffin lid

Masque, it would too

Go on D G Orf, you know you want to. Can we have an animated 3d rendering too?

Ok in simple terms
At some time in the past DIN (the German equivalent of British Standards) have established by some method the safe load that peoples legs can take without breaking in two
The bindings contain a spring which effectively holds a catch in place, the force applied by the spring can be increased or decreased (by turning a screw and altering the DIN setting) the setting needs to change because of the lever action of the ski boot on the bindings, obviosly different foot lengths will act as different length levers and as everyone knows the longer the lever the more force you can exert, however you also exert a different force depending on your weight, thus DIN charts have to take both weight and foot length into consideration.
On to this you then vary the settings according to experience and possibly age, it's generally thoght that more experienced younger skiers will be more energetic and thus wish their bindings to hold them under more extreme circumstances, less experienced skiers are more likely to fall over at lower speeds and thus have settings adjusted accordingly and so on.
Has everyone died of boredom now ?
Doin't say I didn't warn you earlier

D G Orf, Nope, not boring nor long enough to die from....

And love to help out and answer questions and of course, read each other's snow reports.

No one has mentioned elasticity yet.
Or racing settings where bindings are set to only release under forces that would turn mere mortals bones to jelly.
Or pre-releasing.
Come on, some of us are still awake...

and what about lateral pre-release
