Abstract
The invention relates to a boot-retaining unit of a ski binding or snowboard binding, having a boot-retaining element which is retained compliantly by virtue of a spring mechanism, and having a hydraulic impact damper which is arranged parallel to the spring mechanism and is in the form of a piston/cylinder unit. According to the invention, the impact damper contains a hydraulic medium of high viscosity in the rest state and has virtually no tendency to flow, and accordingly, cannot escape at the impact-damper seals even in the course of long rest periods. The cylinder of the impact damper is preferably provided with an external thread and is provided as an adjustment screw for the purpose of changing the spring stressing.
Claims8
A boot-retaining apparatus comprising:
- boot-retaining means for holding a boot to a ski binding or snowboard binding;
- spring means for placing a spring bias on said boot-retaining means;
- hydraulic impact damper means for absorbing dynamic force peaks, and being in an operative relationship with said spring means, said hydraulic impact damper means containing a hydraulic medium having a high viscosity and resistive to leakage in the rest state, and a low viscosity and allowing flow when subjected to a load for damping impact forces applied to said damping means.
