In particular, a standardized sole of an alpine or touring ski boot is provided, which is compatible with alpine or touring ski safety binding systems currently on the market and preferably has a device for further electronically controlled separation of ski boot and ski.

knee injury continue to make up a large proportion of the total casualty volume in skiing, which show statistics in different countries a share of between 30-35%. All ours today ski release bindings on the market are constructed with the aim of the injuries of the lower leg bone (tibia) to avoid. This goal has been largely achieved and at a Tibial fractures can be practically ruled out if properly adjusted. Investigations have clearly shown that there are typical situations in which the knee and especially the anterior cruciate ligament (VKB) can be heavily loaded without being on the ski binding Forces and moments occur that trigger them could bring. This explains the failure of today usual force or moment-controlled bonds in terms of avoiding knee injuries. This problem may be due to electronically controlled triggering systems be solved.

there the separation is triggered by a current or voltage pulse. The logic for triggering this current or Voltage pulse is integrated in a triggering electronics, which in turn is controlled by one or more external signals or is regulated. The sensors can be connected either via cable or via a radio link to be connected to the triggering electronics.

It is already known, ski bindings as so-called safety bindings in which an adjustable torque / adjustable Force between the ski boot and the binding device causes that a locking arrangement of the binding device is opened and then the ski boot is released from the binding device.
