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.
