A device used to mount bindings on a ski has a plate made of viscoelastic material, one of whose faces is joined with the upper surface of the ski and the other of whose faces is joined with a rigid plate on which the bindings can be mounted. The plate of viscoelastic material is not attached in a potion of its surface to the upper surface of the ski and/or the lower surface of the rigid plate. Plates may be provided which have in a central area at least one predeformation oriented in a direction opposite the ski.

Device for mounting a boot on a downhill ski

A ski has a filling core, for example, polyurethane foam, a shell forming an upper face and lateral faces of the ski and a lower face including longitudinal metal edges and a central sliding sole. The ski has two longitudinal reinforcement elements which extend at least in the central part of the ski and are arranged on either side of the core. The two longitudinal reinforcement elements contact the core and at least part of the internal surface of the lateral faces of the ski. Each reinforcement element includes a lower face which extends mainly over a width of a corresponding edge to provide support, and extends over at least a part of a height of the ski.

Shaped ski of non-rectangular cross section

A ski includes longitudinal reinforcement elements that are supported on edges of the ski and that form the lateral sides of the ski. The reinforcement elements also serve to support and fix the sides of a shell of the ski. In one zone of the ski, the height of the reinforcement elements may be substantially equal to the height of the ski, while in at least one other zone of the ski, the height of the reinforcement elements is smaller than the height of the ski. The shell includes a central portion and peripheral wings. In at least one zone of the ski, the central portion of the shell is spaced above the peripheral wings, the central portion being connected to the peripheral wings by a lateral side portion.

Ski comprising narrow sides and an upper shell

A plate, of the type including at least one plate of viscoelastic material fastened onto the upper face of the ski, in its central zone, and on the other face of which a constraining plate made of rigid material is bonded. According to the invention, the capacity of the constraining plate for deformation decreases from its front and rear ends toward its middle.

Plate for mounting a boot binding on an alpine ski

This ski comprises longitudinal reinforcing elements, each bearing on one edge, and forming the sides of the ski, at least one of them extending over a part of the height of this ski, and a shell forming the upper face and a part of at least one of the lateral walls of the ski, and the longitudinal borders of which rest and are fixed on the upper face of the sides, the respective heights of a side and of the shell on at least one of the lateral parts of the ski varying in the same proportions over the length of the ski.

Ski including sides and an upper shell

A device to mount a release binding on a ski has a pair of blocks which are independent of one another. The blocks are mounted on the upper surface of a ski and the bindings are mounted on the pair of blocks. A connector connects the pair of blocks. The connector is inextensible and is mounted on the pair of blocks such that when the ski is flexed the connector prohibits the spreading of the pair of blocks while permitting the pair of blocks to approach toward one another.

Device for mounting a release binding on a ski

A snow surfboard having symmetric construction, but endowed with asymmetric characteristics, a vibration absorption device, composed of at least one vibration absorption element (7, 8), inside or outside of surface (9) of the surfboard, having a relatively small mass, positioned asymmetrically so as to cause vibrations to be absorbed predominantly on the back side (4).

Snow surfboard having asymmetric characteristics

A ski with a non-rectangular cross section has a filling core, for example made of polyurethane foam, a shell forming the upper face and at least a part of the lateral faces of the ski, a lower face equipped with longitudinal metal edges and with a central sliding sole. The ski includes two longitudinal reinforcement elements which extend at least in the binding mounting area of the ski and are arranged on either side of the core, each reinforcement element has a lower face which extends to a great extent over the width of an edge so as to afford it an effective support, and extends over at least a part of the height of the ski, the reinforcement elements not being covered laterally by the shell and thus forming the narrow sides of the ski, at least in the binding mounting area of the ski.

Downhill skis include a plate, positioned at a distance from the top surface of each ski, for holding the bindings. The plate is immovable in lateral directions of the ski. The plate is permitted to be displaced longitudinally with respect to the ski against the action of at least one elastic support at an end of the plate. The elastic support can include a visco-elastic material.

Accessory device for skis, permitting installation of a set of boot

The tapered tip of the ski is extend by an added deflector which has a dissymmetric downstream approximately horizontal part.

Downhill ski with elongated tip

A cross-country ski extending along a longitudinal centerline has a forwardly pointed and tapered shovel, a rearwardly tapered tail, and an intermediate portion extending therebetween and defining a central binding-attachment location. The shovel is at its widest of a relatively great width and the tail is at its widest of a relatively small width substantially smaller than the great width of the shovel. The intermediate portion is comprised of a front intermediate portion flaring smoothly forward from the binding location where it is of the small width to the shovel where it is of the great width and a rear intermediate portion of a constant width equal to the small width and extending between the front portion and the tail.

Skating-type cross-country ski

A projecting nose from the grooved body is engaged in a stirrup to retain the boot on the ridge of a cross-country ski to which the stirrup is pivotally connected by an axis transverse to the ridge. An outer stirrup can be swung relative to the inner stirrup to cause a rod to rise in arcuate windows of the inner stirrup and thereby lift the nose of the boot and clamp it against the fixed crosspiece of the inner stirrup. A detent plate pivotal on an outer stirrup can releasably latch the outer stirrup relative to the inner stirrup.

Binding for cross-country skis

A cross country ski assembly in which the ski has a trapezoidal ridge over at least the greater part of its length over which the longitudinal groove in the sole of a ski-boot casing can fit. The ski-boot casing is articulated to the ski directly or indirectly via a pivot axis located below the upper surface of the ridge.
