Definitions

  • the invention relates to a safety binding heel for a ski boot, that is to say a device for securely holding the back of a boot on a ski by exerting pressure on the heel of the shoe while pressing forward the entire boot against a front attachment device, and ensuring an automatic release of the back of the shoe in case of skier's fall forward. It also relates to a ski on which is fixed such a heel.
  • FIG. 1 A heel, which has become a brand image of the Applicant, is for example described in patents FR2765115 and EP0893146.
  • a heel is schematically represented in FIG. 1. It consists of a tubular cylindrical body 1 comprising at one end a heel catch 2. This body is articulated in rotation around a cam 3 formed in a cylindrical part forming part of a a U-shaped stirrup whose two arms 4 are connected to a pivotally mounted plate 5.
  • This plate 5 is generally mounted on a base itself mounted on a relatively wide slide, fixed on the ski 6, so as to adjust the longitudinal position of the fastener.
  • the body 1 uses the trigger function, which allows to release the back of the shoe in case of significant effort as is the case in a skier's fall forward.
  • the body 1 generally comprises a helical spring, working in compression between a piston bearing 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 the binding before and down against the ski. Only a major effort to tilt 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 a heel of the Applicant comes from the fact that the trigger function is located in the tubular body 1, thereby physically separated from the other main functions of the heel, as the function of adjusting its longitudinal position on the ski.
  • this type of trigger can trigger the attachment to very high forces, particularly suitable for ski racing, unlike the conventional mechanisms mentioned above.
  • US-A-4,863,186 also discloses a safety attachment heel where the spacing of the two arms at the level of the embrace is equal to their spacing at their connection with the cam.
  • the object of the present invention is to provide a simplified heel safety fixing ski boot retaining the above mentioned advantages of the Applicant's solution but does not have the disadvantages.
  • a first object of the invention is to provide a heel that physically differentiates the trigger function of other functions.
  • a second object of the invention is to provide a heel with a small side space to eliminate the risk of hanging snow.
  • a third object of the invention is to provide a heel release maximizing the space in front of the heel gripper to optimize the positioning of the shoe.
  • a fourth object of the invention is to provide a simple heel, low weight and inexpensive.
  • a ski boot safety attachment heel comprising a tubular body having a release function and having at one of its ends a heel gripper for holding the heel of a boot of ski on a ski, this tubular body being articulated in rotation about a cam formed in a cylindrical piece, this cam being secured to two lateral arms connected to a base mounted longitudinally movable on a base intended to be fixed on a ski, distance between the two arms level of the base being less than their spacing at their connection with the cam.
  • the arms may have a V shape in a projection on a transverse plane and their spacing at their connection with the base may be substantially half of the maximum spacing of the arms at their connection with the cam.
  • the arms may have a tilt backwards, this inclination towards the rear of the arms may be of the order of 60 degrees relative to the plane of the base.
  • the arms may be metallic and connected to the base by a connection riveted by at least two fastening pins transversely crossing the base or with the aid of 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 synthetic material and a metal insert at least partially surrounds the cam so as to strengthen the heel.
  • the front length of the part of the base protruding from the heel grip is short, the height of the cam relative to the base is reduced to a height substantially close to the height of the heel of a ski boot.
  • the invention also relates to a ski equipped with such a heel of safety fastening for ski boots.
  • the heel according to one embodiment comprises a tubular body 1 similar to that of the prior art described with reference to Figure 1.
  • This body 1 is articulated around a cam 3, formed in a cylindrical piece, in order to position the heel gripper 2 on the heel of a ski boot 7 in the closed position.
  • Two arms 4 are fixed 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 movably in a longitudinal direction by means of a connection to slides 10.
  • the holding and 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, the longitudinal adjustment function of the fastener, made by the connection between the base 8 and the base 9. In addition, it uses the trigger technology adapted to the ski racing.
  • the space at the front of the heel grip 2 is fully released. There remains only the base. The thickness of the front of the binding and the length of the base are thus reduced. This allows positioning of the sole of the shoe to the lowest, without inconvenience because the size 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 gap smaller than their spacing being at their connection with the cam, even up to substantially half of this maximum gap. Thus, these arms no longer have the disadvantages of risking 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 U-shaped shapes. On the other hand, this shape has the other advantage of allowing the use of narrow slides. , which contributes all the more to the overall reduction of the lateral clutter of the heel.
  • the arms 4 are metallic and fixed to the base 8 by a connection riveted by three securing pins transversely crossing the base 8.
  • the arms 4 can be fixed on the base 8 by means of three through screws . They are further inclined to the rear. Indeed, their base is retracted significantly from their upper part: the slope to the rear is of the order of 60 degrees relative 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 overhang of the release mechanism relative to the connection points of the arms 4 with the base 8
  • the arms 4 form a single piece with the base 8 and the assembly is made of synthetic material.
  • the articulation of the body 1 around the axis of articulation of the cam 3 is reinforced by means of a metal part inserted at least partially around the cam 3.
  • the heel according to the embodiment also greatly facilitates the boot of the ski boot, which can be achieved directly by 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 as shown in Figure 5.
  • a pressure on the heel will allow the boot of the shoe to arrive at the position closed in the heel, as shown in Figure 6.
  • the heel makes a circular arc shown in Figure 5, remaining close to the arms 4 throughout the boot.
