A system for analysis of the performance in use of a sliding board includes a database storing baseline performance; a sensor sensitive to the deformations of said sliding board; and a monitoring body. The monitoring body determines the performance in use based on measurements from the sensor; and compares the performance in use with the baseline performance. The sensor is secured to the sliding board and has at least one piezoelectric element secured to the sliding board and configured to generate electric energy during the deformations of the sliding board; and an electronic processing circuit, powered exclusively by the electric energy generated by the at least one piezoelectric element.

System for analysis of the performance in use of a sliding board

A system for analysis of use of a sliding board comprising at least one piezoelectric element configured to be secured to the sliding board and generate electric energy during deformations of the sliding board; and an electronic processing circuit configured for estimating at least one parameter of use of the sliding board and configured to be connected to the sliding board. The electronic processing circuit is powered by the electric energy generated by the at least one piezoelectric element.

Analysis system and associated sliding board

The present invention relates to a gliding board for cross-country skiing, intended to receive a shoe fastener (F) including an upper face, a lower face and side ridges, characterized in that at least one of the side ridges of the board is provided with a series of notches () whereof each rim () defines, on the one hand, a transverse stop face () making it possible to stop the board in the backwards direction, and on the other hand, a longitudinal connecting face () between the notches () allowing forward gliding.

Gliding board

Braking device for a touring ski comprising a brake () and a blocking device able to occupy a blocking configuration in which the brake () is immobilized by the blocking device in the position of non-braking and a non-blocking configuration in which the brake is able to brake the ski in a braking position, characterized in that the blocking device is mounted with the ability to move in sliding with respect to the brake () so as to occupy the blocking configuration or non-blocking configuration.

Braking device for alpine touring ski

A snow gliding board, integrating a structure element incorporated in a raised end of said gliding board, said element having a plurality of hollowed through openings between its upper and lower surfaces, distributed across its surface, wherein said element comprises in said raised end at least one region free of through openings, separating two areas having through openings, the width of said region being greater than the shortest distance between two through openings in the areas separated by said region.

A ski which when it is flat on a horizontal plane, and loaded at its waist in such a way that the edges touch said horizontal plane at the waist, has a side cut extending between the front and rear contact lines; when it is pivoted around its longitudinal axis and tilted by a non-zero angle &#x3b1; relative to said horizontal plane, and loaded at its waist in such a way that one of the edges touches said plane at the waist, has a side cut extending between two end contact points, front and rear respectively wherein for a tilt (&#x3b1;) equal to 35&#xb0;, the ratio of the distance (D&#x3b1;) separating the front end contact point and the front contact line, related to the distance (D) separating the mid-point () of the shoe and the front contact line, is more than 12%.

Alpine ski

An arrangement for the disengagement of a boot-attachment element on a sliding board comprising at least one receiving element () for receiving a boot-attachment element on a sliding board, the arrangement comprising an automatic disengagement device for releasing the boot from the at least one attachment element, the disengagement device comprising a strip () and/or several articulated link rods () forming a mechanical disengagement device and a lock () making it possible to lock or activate the mechanical disengagement device, the mechanical disengagement device being connected to at least one receiving element () for receiving a boot-attachment element on a sliding board in order to allow its movement beyond a certain force sustained by the receiving element () when the mechanical disengagement device is active.

Boot-attachment device on a ski with safety interface

A gliding board has a raised platform which is intended to accommodate the toe piece and the heel piece of a safety binding on its upper part and which rests on the board via its central part. The platform has its front and rear ends overhanging relative to the upper surface of the board and not resting on the board. The platform has a torsional stiffness such that the maximum angular deformation of a free end under the effect of a twisting moment of four newton-meters exerted at four hundred and sixty millimeters from an engagement zone is less than one and a half degrees.
