 Poster: A snowHead
|
Hi,
I'm starting to get worried about bindings breaking or coming off of the ski. I'm not particularly worried when in normal skiing position but when one leans back to where all of the body weight is hinged on the binding/mount. I'm not particularly heavy (75-77kg) but it's been a growing worry as I lean more and more on my skis (either to sit on the back of the ski or to bend it so that it performs a small jump when the tension is released).
Is this a very unlikely scenario or should I avoid putting such stresses on the bindings?

@s5s, they can break or come off. But it's not something I'd worry about, provided they're properly set up and your weight is in range.
Why are you sitting back? Why are you trying to make it jump? Have you never watched a WC downhiller in slow motion? Can you imagine the stresses?

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

The stresses are immense I'm sure but a large component of the force I put on them is upwards, not sideways if you see what I mean. So while one skis, the stress on the binding is lateral, meaning you're forcing it to move perpendicular to the length of the ski. When you lean back, you create a moment about the heel and there is a large upward force at the front of the binding which is why I was worried the binding bolts might give up.
As to why - just having fun.

@s5s, no the stresses are immense in all directions. Admittedly on heavy duty bindings, but still. Properly mounted bindings should not detach (although it does happen). Plastic ones can break (I have such as they are lightweight and have broken a set, first time in 48 years skiing).
Really not something to worry about.

Yes, bindings can break, I had one shatter on me 1/3 the way down a heavily mogulled itinery.
However
Someone could ski into you.
A ski could fall off a lift & hit you
Etc

You see where it's going?
Don't worry,
If poo poo happens, at least you were having fun at the ti.time.

Try telemarking- the bindings break all the time, my Cobras at least 4 times, Targas at least once- which is why they sell a lot of spares!
Alpine- very very very unlikely- but possible.

Thinking further about load paths in doing what you are @s5s, there's no real tension on the front binding fixings at all. The tips are just not secured in any way so the front binding isn't particularly loaded.
The load path is effectively putting a fulcrum at the rear end of the ski, then flexing the tail to rear binding portion of the ski only. Leaving your centre of mass high and moving it rearward just moves you past the fulcrum, loading the rear of the ski with kinetic energy, which comes back out in the "pop" when you bring your mass forward again.
The front bindings aren't really doing much in the way of load, just stopping the ski falling oft your boot.

I had the base plates underneath the back bindings break - independently the day after each other whilst out skiing.
I swore then I would try and get new ski's every 3 or 4 years as much for the binding as the skis and/or get spend a bit more on a higher grade/quality binding when buying new skis.
Although to be fair the one's that broke probably weren't that old but they were second hand when I got them and I'd done a fair bit of skiing with them. Another factor my have been the kids were quite young and like to do a lot of jumps.
TBH despite the experience it's not something I think about when skiing. As someone else said there are lot of things could go wrong - but thankfully rarely do.

As people above have said, it can happen but it is very rare.
Sitting on the back of your skis isn't great for your ACL's and i would be prepared to bet that your ACL's will snap before your bindings do.
The demographic that you will see ripping bindings most are park and extreme big mountain skiers with the Din's cranked to 18, Hucking big cliff's and going off big kickers.

Only ever seen one binding actually break, and that broke at the rear, not the front. Plastic Tyrolia, broke in the mogul field down to Happy Valley from Schindler in St.Anton.
Why would you be leaning back? That doesn't sound good!
