Slide board for use on snow

A slide board for use on snow, the slide board having in proximity to one of its front and/or rear ends a point of maximum width located beyond a front and/or rear contact line, beyond which a board upturn is defined, the slide board comprising:

• a core extending over the greater part of the board;
• an outer protective layer;
• and
• a first mechanical reinforcement layer disposed between the core and the outer protective layer, the first reinforcement layer extending beyond the front and/or rear contact line along and inclusive of a longitudinal axis, the first reinforcement layer having an extreme longitudinal point located at an intermediate level between the contact line and an extreme point of the board upturn, the first reinforcement layer having an overall cross-section, measured in a plane perpendicular to the longitudinal axis of the board, which increases proximate to the front and/or rear contact line and then, in a zone defined between the contact line and the point of maximum width, decreases moving towards the extreme point of the board upturn;
• and
• a second reinforcement layer covering the first reinforcement layer, the second reinforcement layer extending longitudinally to the extreme point of said board upturn;
• wherein the extreme longitudinal point of the first reinforcement layer forms a thickness step, and the second reinforcement layer follows the thickness step formed by the first reinforcement layer.

• a third mechanical reinforcement layer disposed between the core and the outer protective layer, the third reinforcement layer extending longitudinally and having an extreme point located short of the extreme longitudinal point of the first reinforcement layer.
