Abstract

A device for modifying, dynamically, the pressure distribution of a ski, such as an alpine ski, along its sliding surface. The ski is equipped with front and rear binding elements and support elements for the front and rear ends of the sole of the boot. The device includes a sensor element in contact with the sole of the boot, and additionally, mobile along a vertical direction, a flexion device to generate a flexional moment on at least one front or rear end of the ski, and a connection device between the sensor element and the flexion device to transmit, to the flexion device, at least one part of the vertical thrust of the boot sensed by the sensor element.
