ABSTRACT:
A device for detecting the forces acting onto a ski binding or a shoe held in such a binding comprising at least one feeler emitting electrical signals in dependency from the occurring forces and an evaluating circuit processing the signals. In order to be able to calculate the state of fatigue of the skier and, if necessary, the condition of the binding, it is provided that an integrator circuit constructed as a counter is connected after the evaluating circuit, which integrator circuit is connected to an indicating device and which can be reset merely by means of a manually operable switching device. The counter can thereby count either signals of the evaluating circuit corresponding with predetermined impacts, or digital signals corresponding with impacts having an energy content, or signals which correspond with those impacts, the rising and dropping speed of which exceed a limit value.
