Abstract: The boot comprises a cuff (4) articulated to a shell (1) and a leaf (6) for retaining the cuff which counteract its rearward tilting but give way when the force tending to tilt the cuff exceeds a specific value. These leaf consist of a part (6) which works in compression and gives way by buckling. Such a boot is intended to prevent tearing of the anterior cruciate ligament of the knee.

Abstract: The boot has a cuff (4) articulated to a shell (1) and means for retaining the cuff which counteract the rearward tilting of the cuff but give way when the force tilting the cuff exceeds a specific value. These means consist essentially of a ramp (12) which is integral with the shell or the other component of the boot and against which a bearing element (8) integral with the cuff bears. The ramp and the bearing element can push one another against the action of a spring (9). An escape position allows the cuff to tilt. Such a boot is intended to prevent tearing of the anterior cruciate ligament of the knee.

Abstract: The present invention relates to a ski boot comprising a first component, consisting essentially of a sole and an upper which encloses the foot and the malleolar region, and a second component consisting of a cuff which is articulated with respect to the upper so as to allow the cuff to move from front to rear and vice versa, and means for retaining the cuff which counteract the rearward tilting of the cuff but give way when the force tending to tilt the cuff exceeds a specific value. The retaining means are bistable. They consist of a stop (11) integral with one component of the boot and an elastically deformable part (6), for example a convex leaf, which is integral with the other component of the boot and is intended to be deformed by the stop.

Abstract: A shoe/binding assembly for a gliding board allowing the user's foot to be secured temporarily to said board at a plurality of contact points which, on the binding, consist of attachment means intended to interact with complementary attachment means which are located on the shoe at the front and rear of the sole, wherein at least one of the contact points has a plurality of positions for locking of the attachment means of the shoe by those of the binding, intended to prohibit any movement of the shoe upward and to make it possible to change automatically from one locking position to the next in the downward direction of the shoe, under the effect of the user's weight.

Abstract: A binding (1) retains a ski boot (5) on a ski (3) in a releasable manner. A jaw (4, 4a, 4b) is disposed symmetrically with respect to a longitudinal-vertical plane of symmetry (P). The jaw (4, 4a, 4b) is resiliently biases against a housing by a compression spring (12) acting on a pulling member (9) which is pivotally attached to the jaw by a pin (10). The jaw (4) includes rollers (14a, 14b, 15a, 15b) which help to retain the toe of the ski boot (5) on the ski (3). Two pivot axes (XX', YY') are defined by projections (7a, 7b) that are received in grooves (8a, 8b). The projections (7a, 7b) are defined by the housing (2) and the grooves (8a, 8b) are on a mating surface of the jaw (4, 4a, 4b), or vice versa. The pivot axes (XX', YY') are not symmetric with respect to the plane of symmetry (P). One of the axes is displaced a further distance (d) from the symmetry plane (P) than the other such that they operate on the compression springs with different effective lever arms (D1, D2).

Abstract: A ski, or board for sliding on snow, having a platform for receiving and elevating the bindings of the boot including lateral edge protrusions which serve as feet for supporting this platform.

Abstract: A pair of skis, of the type incorporating a shell, comprising, for each ski, at least one lateral reinforcing edge. The point of maximum height of the lateral reinforcing edge of the inner edge is offset forwardly or rearwardly with respect to a transverse line plane corresponding to all points of maximum height of the ski.

Abstract: 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.

Abstract: This invention relates to a board for sliding over snow, such as a ski, snow surf or the like, provided with at least one vibration damper (9, 10) made of visco-elastic material (3) and plate or other stress element (4). At least one of these dampers (2, 5) has a complex section, for example an upturned U, so that it partially follows different planes (7, 8, 9) of the zone of the structure (1) on which it is added.

Abstract: 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.

Abstract: Process for the manufacture of a complex moulded structure, constituted by a foam core (16) made from plastic and on its periphery by two, respectively upper (11, 12) and lower (6, 8, 9), half-shells, includes the following steps:depositing in a mould (1, 2) a first element (6, 7, 8, 9) intended to form the lower half-shell,depositing on this first element (6, 8, 9) a deformable tubular element (13, 14, 17);depositing on top of this deformable tubular element (14) a second element (11, 12) intended to form the upper half-shell,closing the mould,injecting into the deformable tubular element (13, 14, 17) reactants intended to react in order to form a foam which expands in situ until pressing the element (11, 12) against the walls (3, 4, 10) of the mould,cooling the contents of the mould,and finally opening the mould in order to withdraw the complex moulded structure thus obtained, characterized in that at least the upper portion of the deformable tubular element (14) is rigid.
