Abstract: A board for gliding for downhill skiing, having, at least in its underfoot zone: a lower gliding surface composed of a sole plate bordered by metal edges; a topsheet substantially parallel to the lower gliding surface, on either side of the center longitudinal plane of the board; lateral reinforcement elements located in line with at least one part of the bead of the metal edges; lateral faces extending between the top part of the lateral reinforcement elements and the topsheet, said lateral faces having recesses located below the plane of the topsheet and opening out in the latter; wherein these recesses form a hollowed zone connected to the reinforcement elements, and wherein the lower part of the recesses has a slope that is inclined longitudinally relative to the lower gliding surface and the topsheet.

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.

Abstract: A raising platform (6) is intended for mounting on the upper surface (3) of a board (1) for gliding over snow in order to receive and to raise the bindings securing a user's boot to a board (1) for gliding over snow. The raising platform (6) is divided into two longitudinal parts (9, 10) that are each placed directly on the upper surface (3) of the board (1) for gliding over snow and that are connected together by at least one bridge (11).

Abstract: A board for gliding for downhill skiing, of “shell” type construction having, at lest in an underfoot zone a lower gliding surface composed of a sole plate bordered by metal edges and a topsheet substantially parallel to the lower gliding surface, on either side of the center longitudinal plane of the board. The underfoot zone further includes lateral faces extending between the metal edges and the topsheet, the lateral faces having recesses located below the plane of the topsheet and opening out in the latter. The base of the recess forms a slope that is inclined longitudinally relative to the lower gliding surface and the topsheet.

Abstract: A raising platform for a binding for a board for gliding over snow, including a planar central zone capable of receiving the front stop and the heel piece of the binding, and two lateral portions of which the lower edge is intended for interacting with the board for gliding, wherein the lower edge of the lateral portions has, in a longitudinal plane, a certain gradient relative to the plane of the central zone.

Abstract: Alpine ski comprising a front area known as the tip area (2), a rear area known as the tail area (4), and an intermediate area known as the mid-section (3) designed to receive a stop (12) and a heelpiece (13) comprising the binding of the boot of a skier. In this ski, the rigidity, namely the resistance to flexing in the lengthwise direction of the ski, of the center part of the mid-section (3) is less than the rigidity in the two end parts of the mid-section (3), namely the parts that connect with the front (2) and rear (4) areas.
