Abstract: A ski sport apparatus having a ski with a middle section and two outer sections. An interface device connected to the ski, with a binding region for accommodating a ski binding is arranged in the middle section. The ski sport apparatus has at least two force introduction regions distanced to one another in the longitudinal direction, for introducing forces from the interface device into the ski. The ski in the longitudinal direction has several regions of lower or higher flexibility alternating in the longitudinal direction. The middle section of the ski has a region with a higher flexibility. A frontmost and/or a rearmost force introduction region is allocated to a region with a lower flexibility of the ski and in the longitudinal direction is arranged further to the front or further to the rear than the binding region. The ski has good curve dynamics, has a good ski guiding and excels with an incomparable running smoothness.

Abstract: A ski binding assembly plate which can be fixed or can be adjusted in forward inclination and height wherein the pressure on the front guide part of the ski is increased. Because the ski binding assembly plate is fastened on the ski with a two-point support and arrest system, the ski obtains a free bending moment, by which means the ski is dynamic and runs very smoothly. A wedge function and a force transmission system prevent the ski from being propelled back by the counter pressure in the region of the ski binding. With a damping system, vibrations and knocks are absorbed. The plate may be equipped with any brand of ski binding. It fits each type or brand of ski. The individual adjusting possibility of this plate permits the adaptation, which suits each ski, each skiing style and each technical level of the skier.
