Definitions

  • the invention relates to a shoe safety attachment heel ski, that is to say a device intended to maintain in a secure manner the back of a shoe on a ski while exerting pressure on the heel the shoe while pressing forward the entire shoe against a front fixing device, and by ensuring automatic from the back of the shoe if the skier falls forward. It also relates to a ski on which is fixed such a heel.
  • a heel which has become a brand image of the Applicant, is for example described in patents FR2765115 and EP0893146.
  • Such a heel is schematically represented in FIG. composed of a tubular cylindrical body 1 comprising at one end a grasping heel 2.
  • This body is articulated in rotation around a cam 3 formed in a cylindrical part forming part of a U-shaped stirrup whose two arms 4 are connected to a pivotally mounted plate 5.
  • This plate 5 is usually mounted on a base itself mounted on a relatively wide slide, fixed on the ski 6, so as to be able to adjust the longitudinal position of the binding.
  • Body 1 implements the trigger function, which releases the back of the shoe in case of significant effort as is the case in a fall of the skier to forward.
  • the body 1 generally comprises a spring helical, working in compression between a piston resting on the cam 3 and a stop located towards the end opposite the cam.
  • the shape of the cam 3 is such that under the effect of spring pressure, the shoe 7 once pavement is pressed forward against fixing before and towards down against the ski. Only a major effort can rock the body 1 around the cam 3 by pushing the piston and compressing the spring, which triggers the opening of the heel.
  • the advantage of such Applicant's heel comes from the fact that the trigger function is in the tubular body 1, thereby physically separated other main functions of the heel, such as the function of adjusting its longitudinal position on the ski.
  • the object of the present invention is to provide a simplified heel safety binding for ski boots retaining the benefits mentioned above of the Applicant's solution but not possessing not the disadvantages.
  • a first object of the invention consists in proposing a heel that physically differentiates the triggering function of other functions.
  • a second object of the invention is to propose a heel piece with a Small lateral footprint to eliminate the risk of hanging snow.
  • a third object of the invention is to propose a heel freeing up the space in front of the heel grip to optimize the positioning of the shoe.
  • a fourth object of the invention consists in proposing a heel simple, low weight and inexpensive.
  • a heel of safety binding for a ski boot comprising a tubular body having a trigger function and having at one of its ends a heel grip intended to hold the heel of a shoe on a ski, this tubular body being articulated in rotation around a cam formed in a cylindrical part, this cam being integral with two lateral arms connected to a base mounted longitudinally movable on a base intended to be fixed on a ski, the spacing of the two arms level of the base being lower than their spacing at their connection with the cam.
  • the arms can have a V shape in a projection on a transversal plane and their spacing at the level of their connection with the base may be substantially half of the maximum spacing of the arm at their link with the cam.
  • the arms may have a backward inclination, this backwards inclination of the arms, which can be of the order of 60 degrees compared to the floor plan.
  • the arms can be metallic and connected to the base by a connection riveted by at least two crossing pins transversely the base or using at least two through screws.
  • the axis of the cam and the first axis of attachment are substantially in the same vertical plane.
  • the arms and the base form a single piece of material synthetic and a metal insert at least partially surrounds the cam in order to strengthen the heel.
  • the front length of the part of the pedestal protruding from the heel grip is short, the height of the cam relative to the base is reduced to one height substantially close to the height of the heel of a shoe of ski.
  • the invention also relates to a ski equipped with such a binding heel security for ski boots.
  • the heel piece comprises a tubular body 1 similar to that of the prior art described in This body 1 is articulated around a cam 3, formed in a cylindrical piece, in order to position the heel grip 2 on the heel of a ski boot 7 in the closed position.
  • Two arms 4 are attached on the one hand to the lateral edges of the cam 3 and on the other hand to a base 8, itself mounted on a base 9 in a movable manner according to a longitudinal direction by means of a sliding link.
  • the longitudinal movement of the base 8 on the base 9 are made by means known from the prior art, not shown.
  • the base 9 is intended to be fixed on a ski.
  • the heel separates completely the trigger function, contained in the body 1, of the longitudinal adjustment function of the fastener, made by the connection between the base 8 and the base 9.
  • Trigger technology adapted to ski racing.
  • the space at the front of the heel grip 2 is fully released. It remains more than the base.
  • the thickness of the front of the binding and the length of the base are reduced. This allows a positioning of the sole of the shoe at the lowest, without being inconvenienced because the clutter is reduced, easier even when there is snow stuck under the shoe for example.
  • the height of the arms is reduced to a height substantially equal to that of the heel of the shoe.
  • the arms 4 have at their base, at their connection with the base 8, a spacing smaller than their spacing being at their level. connection with the cam, even up to substantially half of this maximum spacing. Thus, these arms no longer have the disadvantages to risk rubbing on the snow. As it appears in FIGS. 3 and 4, they have a V shape in a projection on a transverse plane, contrary to the usual forms in U. On the other hand, this form has for another benefit of allowing the use of narrow slides, which participates even more in the overall reduction of congestion lateral of the heel.
  • the arms 4 are metallic and fixed to the base 8 by a riveted connection by three solidarity axes transversely crossing the base 8.
  • the arms 4 can be fixed on the base 8 with three screws therethrough. They are further inclined to the rear. Indeed, their base is found significantly backward from their upper : the slope towards the back is of the order of 60 degrees compared to the base in this embodiment (see Figure 6).
  • This geometry allows a quasi-alignment in the same vertical plane of the cam 3 and the first fastening axis 11, which significantly reduces the cantilever the trigger mechanism with respect to the connection points 4 arms with the base 8.
  • the arms 4 form a single piece with the base 8 and the assembly is made of synthetic.
  • the articulation of the body 1 around the axis of articulation of the cam 3 is reinforced with at least one inserted metal part partially around the cam 3.
  • the heel according to the mode of execution also greatly facilitates the boot of the ski boot, which can be made directly pressing the heel on the heel gripper 2 in the open position, according to a technique commonly called "step in”.
  • step in the heel is first positioned on the heel grip 2 of the heel in the open position of the as shown in Figure 5. Pressure on the heel is allow the boot of the shoe to arrive at the closed position of the heel, as shown in Figure 6. During this phase the heel forms an arc represented in FIG. 5, thus remaining close to the arms 4 throughout the boot.
