The DIN setting specifies the correct trigger values for the binding of ski shoes. This should prevent injuries while skiing. These injuries can happen if the binding releases the shoes either too early or too late. Both
can be very dangerous. That's why a compromise needs to be made.
The goal is to reduce the torque applied to the shin of the skier. By using empirical studies the standard DIN/ISO 11088:2006 was written.
The calculated value is directly adjusted at the front and back part of the binding. The value corresponds to the torque but only under perfect circumstances. The actual setting depends on the combination of binding and shoes and can differ from the calculated value.
Mz and My are the trigger values of the binding. Mz is the torque (in Nm) to trigger the binding during rotation of the ski shoes. My the trigger value for the front tilt. Mz is measured on the front part of the binding, My on the back part. But it is adjusted on the triggering scale using the DIN setting.
The weight of the unclothed skier is needed. The value must be given in kilogram (kg).Height
The height must be given in centimeter (cm). It is measured from head to toe – without helmet or shoes.Shoe sole length
The sole length must be given in millimeters (mm).Age
The age of the skier is needed in years.Driving type
Slow, careful to moderate ride in an easy terrain with a low slope. This category usually is for beginners.Advanced
All skiers that are neither Beginner nor Expert are Advanced skiers.Expert
High speed and aggressive skiing style in terrain with a medium to steep slope. The skier must weight at least 22 kg.
A correctly calculated DIN setting, that is perfectly adjusted at the binding is no guarantee. It is possible that the binding does not work as expected. It is more likely to happen with older bindings than with new ones. But even with new bindings you can't be completely sure. Additionally the combination of binding and shoe can lead to a change. For example if the sole of the shoe and the binding plate are rough the increased friction must be overcome during a rotation.
The binding should always be adjusted by a specialist with the ski shoe and used ski. The specialist measures the actual trigger values. With this value the binding is adjusted until the correct amount of torque is reached. A proper specialist should give you an document about his adjustments.
Finally there are a couple more adjustments to fit the binding perfectly for the ski shoe. Specialist are the best choice for these adjustments. If you think you can adjust the binding on your own, do so on your own risk.
Did you ever have this feeling that something is wrong with your binding? Maybe it was pure chaos at the ski rent on Saturday morning and you're not sure the guy behind the counter did everything right. To be sure you can calculate the DIN setting on your own and may complain about his adjustments.
