The ski with the general reference (1) is a set of elongated shapes, having a median vertical (P) plane of general symmetry, the front of which is raised to form the spatula (8).

The ski (1) is constituted by a main part that we will call body or base (2) on the upper surface (17) of which is fixed at least in the region of the pad (4) a complementary element (3) intended to receive the retaining clip (27a, 27b) of the user's boot.

The base (2) is the element in contact with the snow and has the shape of an elongate beam having on its lower surface a sliding sole (6) laterally bordered by lateral edges (7a, 7b) of metal.

The base (2) is an elongate beam whose front end is raised to form the spatula (8) of the ski. This base (2) has its own distribution of thickness, coastline, width and stiffness and can be of all types of structures, geometries and constitutions.

Thus, the elongate beam constituting the base (2) can be of all types of structures such as those known to date as, for example, of the sandwich type, of the box type, or even mixed and consisting of a set of elements. and components known per se.

The complementary element (3) is in the form of an elongated plate comprising two lateral edges (9a, 9b) extending between a front end (10) and a rear end (11).

The width (T1) of the complementary element (3), namely, the width (T1) measured between its lateral edges (9a, 9b) is less than or equal to the width (T2) of the base (2) to the place of measurement. According to a feature of the preferred embodiment of the invention, the complementary element (3) is such that at least one of its lateral edges (9a and / or 9b) comprises a hollow profile (12) so that said complementary element (3) comprises a front part (13) connected to a rear part (14) by a median part (16) comprising a zone of smaller width (15). It will be noted that the length (L1) of the complementary element (3) is less than the length (L2) of the base (2). By way of example, it will be noted that the length (L1) of the complementary element (3) can be between 30% and 70% of the length (L2) of the base (2). Thus the length (L1) of the complementary element may have, for example, a length of between 50 and 120 centimeters.

According to the preferred embodiment of the invention, it is the internal lateral edge (9a) which comprises the recessed profile (12) intended to cooperate with the internal damping abutment, the internal lateral edge being for a right ski arranged on the left side, and for a left ski on the right side.

As for the base (2), the complementary element (3) has its own configuration and structure. It has its own distribution of thickness, width and stiffness and can be of all types of constructions. Thus, said complementary element (3) can be a one-piece element made of a single material. However, it may be of a completely different design, such as, for example, that the front part (13) is different in its material and / or its design of the rear part (14), or as in the variant of FIG. 11.

According to the preferred embodiment of the invention, the lateral retention of the middle part (16) of the complementary element (3) is made by bearing on the lateral damping abutment (5). According to this embodiment, the lateral damping abutment (5) is constituted by a damping element (50) integral with a lateral retaining projection (18) fixed to the base (2). This lateral retaining projection (18) is disposed at the level of the recessed profile (12) of the complementary element (3). It is fixed to the base by any appropriate means such as screws or by gluing, welding or otherwise. In addition, it includes an outer wall substantially planar and an inner wall advantageously curved, covered with a layer of damping material, elastically deformable constituting the damping element (50) which, in cooperation with the projection, constitutes the internal damping abutment (5) . It is understood that the form of cooperation between the lateral damping abutment (5) and the recessed profile (12) which are of complementary shapes, also allows a longitudinal retention of the complementary element.

According to the embodiment shown in FIGS. 1 to 10, the front part (13) of the complementary element (3) consists of two front longitudinal arms (13a, 13b) extending from the central part (16) towards the before (10). Similarly, the rear portion (14) of the complementary element (3) is constituted by two rear longitudinal arms (14a, 14b) extending from the middle portion (16) rearward (11).

Thus, the front portion (13) comprises an inner front arm (13a) and an outer front arm (13b) which extends parallel to the outer front arm and separated from the latter by a front longitudinal space (19). Similarly, the rear portion (14) includes an inner rear arm (14a) and an outer rear arm (14b) that extends parallel to the outer rear arm and is separated therefrom by a rear longitudinal space (20).

The complementary element (3) is fixed to the base on its upper surface by means of fasteners, which can be of any kind, but which, according to the embodiment given by way of example, are constituted by fixing screws. Thus, according to the preferred embodiment, the front portion (13) and the rear portion of the complementary element (3) are each fixed by fastening means to the base, ensuring a locking relative lateral displacement between said element and the base, and a release of the relative longitudinal displacement. Furthermore, the central portion (16) of the complementary element (3) is fixed to the base by fastening means ensuring locking in longitudinal translation of the complementary element relative to the base and allowing a transverse displacement relative to said base.

Thus, the front portion (13) of the complementary element is fixed to the base by two fixing screws, a left front screw (21a) and a front right screw (21b), each of the screws passing through a corresponding oblong hole, extending longitudinally, respectively a left elongated hole (22a) and a right elongated hole (22b). Similarly, the rear portion (14) of the complementary element is fixed to the base by two fixing screws, a left rear screw (23a) and a front right screw (23b), each of the screws passing through a corresponding oblong hole. , extending longitudinally, respectively a left elongated hole (24a) and a right elongated hole (24b).

Furthermore, the central portion (16) of the complementary element (3) is fixed to the base, for example, by two screws (25a, 25b) each passing through a corresponding oblong hole (26a, 26b) extending transversely . The screws (25a, 25b) can be positioned in the middle of the corresponding oblong hole (26a, 26b) to allow lateral displacement on either side of the screws (25a, 25b) of the central portion (16). But these screws could be in contact with one end of the oblong holes (26a, 26b) to allow lateral movement only on one side, and more precisely on the side of the lateral support (5).

FIG. 6 is a view from above showing an alternative embodiment in which the complementary element (3 ') and, in particular, its median part (16), and more particularly its lateral recessed profile. (12) is supported laterally by its two lateral edges, on a lateral damping stop (5). Thus, the base (2) comprises two lateral damping stops, one on the inner side and one on the outer side. Of course, the ski could be such that the complementary element (3) is in lateral support on a damping stop on its outer side.

According to the embodiment illustrated in Figures 1 to 6 and 8 and 8a, the damping stop (5) is constituted by a damping element (50) integral with a lateral retaining projection (18) fixed to the base (2), but it could, of course, be otherwise. The damping stop (5) could thus be a one-piece piece made of a deformable elastic material, fixed to the base as shown in Figures 7 and 7a.

Note also that the lateral retaining projection (18) which, according to the embodiment described above, is an independent piece of the base on which it is fixed, could be an integral part of the base, as shown in FIGS. Figures 8 and 8a; protruding against which the damping element (50) would be fixed, for example, by gluing, welding or other.

FIG. 9 is a view similar to FIG. 3 illustrating an alternative embodiment in which the damping element (50) is bonded to the complementary element (3) while being, for example, glued to the lateral edge of the side recess profile (12) formed in the middle part, while the lateral retaining projection (18) is connected to or integral with the base (2).

According to the embodiments illustrated in FIGS. 1 to 9, the complementary element bears against the damping lateral abutment by at least its median part. Thus, the damping lateral stop is located at the middle portion (16) of the complementary element (3), to cooperate with the recessed profile (12) located therein, but the damping lateral projection could extend forward and / or towards the rear, to extend beyond the area of the recessed profile (12), and also to laterally retain by damping the lateral border (9a, 9b) of the front part (13) and / or of the lateral border (9a, 9b) of the rear part (14) of said complementary element (3).

FIG. 10 illustrates an example of such a variant in which the inner side of the ski (1) is such that the complementary element (3) is retained laterally by a lateral damping stop (5) which extends from the part a forward and a rearward-sloping central unit for laterally damping the side edge (9a) of the front part (13) and the side edge (9a) of the rear part (14) of said complementary part ( 3).

Figure 11 is a top view of an alternative embodiment of a complementary element. According to this variant, the inner front arm (13a) and the inner rear arm (14a) are with the middle part (16) made with a first material (M1), while the outer front arm (13b) and the outer rear arm (14b) are made of a second material (M2) different from the first material (M1). Said materials may, for example, be a filled polyamide, or a thermoplastic elastomer, or any other suitable material.

Figure 12 is a top view of a ski according to an alternative embodiment of the complementary element. According to this variant, the lateral damping abutment is not recessed by shape cooperation in a complementary element as in the previously described embodiments. In this variant, the complementary element (3) is a simple rectangular plate whose lateral edges are linear, at least its edge in contact with the damping lateral abutment, while the damping stop is also rectangular.

The damping lateral abutment (5) and / or its damping element (50) are of elastically deformable material, such as, for example, of viscoelastic material and, for example, of rubber, of rubber elastomer, of viscoelastic rubber, or any other equivalent or appropriate material. It is also true that the lateral damping abutment (5) and / or its damping element (50) may be constituted by a deformable elastic blade such as, for example, metal or made of composite material.

Of course, the invention is not limited to the embodiments described and shown by way of examples.
