Ski binding

The SNS profile cross-country ski binding has a metal axle that clicks into the binding.

As a ski binding (in Austria ski binding ) the part is of a ski denotes that the ski boot connects to the ski. Depending on the ski, there are a wide variety of ski bindings, which are mainly characterized by different ways of attaching the boot to the ski. In Nordic skiing ( e.g. cross-country skiing ) and telemarking , the shoe is only attached to the ski with the tip of the shoe, while the heel remains free; in alpine skiing , on the other hand, both toe and heel are connected to the ski.

In addition to the connection between boot and ski, the ski binding ensures correct power transmission from the foot to the ski, especially with alpine skis, which is important for sensitive control of the ski. The ski binding is also essential for the safety of the athlete, which is why an alpine ski binding is often referred to as a safety binding . A safety binding connects the boot with the ski until a certain limit of the force is exceeded. When the load is higher, the binding releases and the ski separates from the boot. If the trigger value is correctly set according to the athlete's ability and the maximum stress level, injuries from bulky skis on the feet can be avoided in the event of a fall (see also: skiing accident ).

The NNN binding does not have a middle bar, but two side bars.
The SNS pilot binding uses a second metal axis in the shoe for a tension spring (white) for stabilization.

For cross-country skis , three binding systems that are incompatible with one another are available in German-speaking countries : SNS (Salomon Nordic System) Profil, SNS Pilot and NNN (New Nordic System). While with the SNS Profil and NNN the shoe is kept moveable on the binding with a metal axis, with the SNS Pilot a second metal axis in the shoe and an associated metal rail ensure increased lateral stability (especially in the skating style).

With carving skis , a plate (damping plate, heightening plate) is often mounted between the ski and the binding. Newer ski constructions, especially the cap construction, allow ski manufacturers to integrate the binding system directly into the ski. For sports retailers this makes assembly easier, but integrated binding systems also have disadvantages for consumers, since used bindings can no longer be mounted on newly purchased skis.

For touring skis there is a special combination of safety and Nordic binding, the touring binding . It only fixes the tip of the shoe for the ascent, while the heel remains free. The heel can be fixed for the descent. Many modern touring bindings, especially the so-called freeride models, meet the requirements for safety bindings suitable for slopes.

So-called vario ski bindings allow the heel and front automatics to be moved quickly in order to either quickly adapt the binding to another ski boot or to move the ski boot on the ski, e.g. B. to achieve a different center of gravity.

Ski bindings, ski boots and the procedure for correctly setting a safety binding are standardized in accordance with various international standards (e.g. ISO 11088 ).

In skiing, false triggering is the automatic opening of the binding in a situation in which this is not desired. Incorrect triggering can be caused on the one hand by a too soft setting of the binding, but also, if the setting is correct, by repeated hits on the ski. If strong impacts on the ski are repeated in a very short time, the binding cannot fully recalibrate, so that the next impact causes the binding to snap open, which is a false release.
