Abstract: A ski includes a base plate (2) and a raised, central platform (3). A front supplemental element (6a) is removably attached to a front end of the platform and has a pair of longitudinal arms (60, 61) extending forward along a top surface of the base plate. Similarly, a rear supplemental element (6b) is removably attached to the rear of the platform and has a pair of longitudinal arms (62, 63) which extend slidably along the top surface of the base plate. The supplemental elements are removably attached using a tongue (8a, 8b) and slot (9a, 9b) arrangement and a latch (10, 11, 100). A visual indicator (11, 12; 15, 16) indicates when the supplemental element is properly connected. The supplemental elements include a basic structure (600) with supplemental reinforcing elements (601) removably attached to the undersides of the longitudinal arms.

The bridge is prestressed in order to augment the pressure applied by the boot during skiing to forward and rearward portions of the base plate and to provide a dynamic means of recall for returning the base plate toward a home position.

Abstract: A snow sliding board (1) such as a ski, a snow board or a surf board has a vertical plane of general symmetry (P). A principal portion, called body or base, includes at least in the area of the sole a complementary, longitudinal element intended to receive the binding for retention of the user's boot The base (2) has the shape of an elongated beam, comprising a sliding sole, whose front extremity is raised in order to form a spatula, with the complementary longitudinal element having the shape of an elongated plate, limited laterally by a lateral left rim and a lateral right rim. The complementary element additionally includes a front portion connected to a rear portion by means of a middle portion. At least one of the lateral rims of the complementary element acts as lateral support, via at least its middle portion, on a lateral shock absorbing stop of deformable elastic material.

Abstract: A board for gliding that has an underfoot zone for receiving the foot or feet of the user that extends toward the front of the board by a tip zone and to the rear of the board by a heel zone. The board further including a lower assembly containing a protective layer and reinforcement. An intermediate core is located between the two assemblies. A plate is located in the underfoot zone that is displaceable in the direction of the lower assembly by foot pressure exerted by the user. A rigid arm is mounted in the board transverse to the core so that one end of the other end bears upon the underside of the plate. Forces exerted by the user on the upper surface of the board are transmitted to the lower surface of the board by the ends of the arm.

Abstract: A gliding board, including: an injected polyurethane foam core; lateral reinforcing elements, which form some or all of the edges of the board; at least one internal reinforcement, which is in the form of a solid layer; and two outer layers, of which the lower layer forms the gliding surface and the upper layer forms the protective layer. The internal reinforcement rests on recesses which are provided for this purpose in each of the lateral reinforcing elements. The internal reinforcement has notches on its side profiles so that, level with the notches, the injected core passes through it in order to at least partially occupy the volume defined between the internal reinforcement and at least one of the two outer layers.

Abstract: A ski construction such as a ski, monoski, or snow board includes a principal base support (2) which has a sliding sole (6) that is raised to form a tip (8) at its front end. An upper surface of the ski defines a housing or pocket (20) with a central contracted region defined by lateral projections (18a, 18b). One of a family of elongated complementary elements (3) with hollow profiles (12a, 12b) is frictionally received in the pocket. The complementary elements can have different lengths, thicknesses, stiffness, constructions, or material properties. By selecting among the family of complementary elements, a common principal support base can be configured to have a variety of skiing characteristics which complement the skiing abilities of a variety of skiers, skiing conditions, and the like.
