Ski or snowboard with a means for influencing its geometry

Ski or snowboard in the form of a board-type gliding device, with a multi-layered gliding board body at least comprising

• at least one strength-imparting top belt,
• at least one strength-imparting bottom belt,
• at least one core disposed in between,
• at least one top layer forming the top face of the gliding board body
• and at least one running surface facing forming the bottom face of the gliding board body,
• and, by reference to the width of the gliding board body, at least one slot is provided in its middle portion disposed in the depth direction extending from the top face of the gliding board body in the direction towards the running surface facing and in its longitudinal direction extending essentially parallel with the longitudinal direction with a view to causing a cross-sectional weakening and reducing the stiffness of the gliding board body transversely to its longitudinal direction
• and having at least one geometry-influencing means in order to produce a cross-sectional shape or contour of the gliding board body which is variable as a function of load and/or can be manually varied,
• wherein the geometry-influencing means comprises a plate-type force-transmitting element which extends across more than 50% of the length of the gliding board body and is supported within its longitudinal extension in at least part-portions on the top face of the gliding board body so as to transmit load, and the plate-type force-transmitting element is disposed so that it overlaps the at least one slot in the longitudinal direction and bridges it transversely to the longitudinal direction of the slot.
