Definitions

  • the present invention relates to the field of the practice of winter sports. It relates more particularly to a boot for skiing and a ski binding, particularly a rear ski binding. The invention relates particularly to downhill skiing and ski touring.
  • an alpine ski boot sole is necessarily rigid, not only to ensure good transfer of forces between the boot and the ski, but also because the sole serves as a reference for the connection to the binding.
  • the heel 10 of an alpine ski boot has an overhang 12.
  • the top 14 of this overhang and the outer surface of the sole which forms the underside 16 of the overhang are the functional zones which cooperate with the rear binding of the skis, which forms a jaw which encloses the top and the bottom of the overhang.
  • the height between this overhang and the outer surface of the sole is the standard dimension according to which the rear bindings of the skis are standardized. Consequently, it is not possible to provide for including cushioning in the heel of the shoe.
  • the wear that the sole and its heel may exhibit may become detrimental to the operation of the binding by inducing a harmful play.
  • alpine ski boots must be smooth and slippery to ensure proper operation of the safety of the binding and not to hinder the relative movements of the boot with respect to the ski, in the event of the safety boot.
  • these shoes exhibit poor grip on slippery or frozen ground, which is frequently encountered in winter conditions.
  • one of the standards mainly used, called “Low tech” has a binding in two independent parts, one for the front of the boot and the other for the rear ( fig. 2b ).
  • the rear part of the binding has two rods 20, movable transversely with respect to the ski, that is to say perpendicular to the longitudinal axis of the ski and parallel to the main plane of the ski.
  • These rods 20 can come to take place in housings 22 which a metal part 24, visible on the figure 2a , inserted and fixed in the heel of the shoe.
  • This metal part has ramps 26 with which the rods cooperate during the engagement of the boot in the binding, to separate them and allow their introduction into the housings 22.
  • the ramps 26 descend almost to the level of the outer surface of the sole 16.
  • the boot is then suspended on the rods 20 , the heel 10 not being in direct contact with the surface of the ski.
  • This system is particularly advantageous, because it makes it possible to have an adherent or worn sole, without prejudice to the operation of the binding.
  • this metal part 24 arranged vertically on the heel and essential for the operation of the connection system with the binding limits to a few millimeters (less than 10mm), the sole height that can be used for a damping layer.
  • the lateral rigidity of the binding is relatively poor, due to the small distance (20mm) between the rods, imposed by the standard.
  • the object of the present invention is to propose a new rear binding standard, with a new boot and a new binding, making it possible at least partially to overcome the aforementioned drawbacks, both in the field of alpine skiing and ski touring.
  • the invention relates to a ski binding and an assembly of a ski binding and a boot, as defined in the claims.
  • FIG. 3 there is shown a boot for skiing, described here by way of illustration.
  • This comprises a sole 30 intended to be in contact with the ground during walking phases, and a rod 32 covering the foot, drawn schematically.
  • the rod 32 generally includes tightening loops.
  • the rod 32 can be associated with a collar, mounted articulated on the rod, which maintains the lower leg of the skier.
  • Certain boots, particularly those intended for ski touring, offer a "Walk" position and a "Ski” position, in which, respectively, the articulation between the rod and the collar is free (or minimally constrained), or blocked.
  • the boot comprises an attachment interface 34 located at the heel, intended to cooperate with the rear part of a ski binding.
  • the grip interface 34 defines a first reference surface 36, said to be lower, located on the side of the sole and parallel to the latter.
  • the attachment interface 34 will be described in detail later.
  • the sole 30 comprises at least at the level of the heel of the shoe, a layer made of a damping material, capable of performing a cushioning function when the heel is placed, in the walking phases.
  • a damping material capable of performing a cushioning function when the heel is placed, in the walking phases.
  • This type of material natural (rubber, etc.) or synthetic (polyurethane, EVA, etc.) is well known in the field of footwear, in particular for sports, and does not need to be described further.
  • the sole 30 is multilayer, and a strong and adherent outer layer, advantageous for walking phases, forms the outer part of the sole and is intended to be in contact with the ground.
  • the surface of the sole intended to be in contact with the ground defines a second reference surface 38, said to be external.
  • the layer of damping material can form up to 100% of the thickness of the sole at the level of the heel. This layer can also occupy only a limited volume of the heel, for example by not occupying the entire surface of the latter, since the other materials which form the sole do not prevent the layer of damping material from d 'to be efficient.
  • the layer of damping material is located at least between the lower reference surface 36 and the outer reference surface 38.

  • the attachment interface 34 comprises a projecting element 40 intended to cooperate with the binding.
  • the protruding element 40 is arranged transversely, that is to say perpendicularly, relative to the axis of the foot of the shoe.
  • This projecting element 40 comprises two flanges situated in planes parallel to the external reference surface formed by the sole. These two edges respectively define a first plane called lower and which forms the lower reference surface, located on the side of the sole, and a second plane, called upper.
  • the projecting element 40 protrudes from the surface formed by the rear of the heel, by at least 5mm. It is this projection of at least 5mm which defines the two edges. As can be seen better at the figure 12 , the edges of the lower and upper planes may have slightly different lengths, depending on the configuration of the shoe. It will be noted that the smallest of the flanges protrudes by at least 5mm with respect to the rear part of the boot situated in its plane. The protruding dimension is taken in the sagittal plane of the shoe.
