Definitions

  • the present invention relates to a safety binding of a boot on a ski, and more particularly to a safety binding comprising in particular lateral jaws intended to hold the boot in the service position on a ski.
  • the aim of the present invention therefore consists in providing a safety binding which overcomes the aforementioned drawbacks of known safety bindings with front stop and heel piece, by creating the conditions such that the binding is capable of completely neutralizing the additional torque due to parasitic friction and that the effects of jamming due to the twisting of the shoe in the front stop are eliminated.
  • object of the invention which comprises two lateral jaws mounted movable under the action of an elastic member in a plane parallel to that of the ski, between a closed service position in which these jaws cooperate with the sole of the shoe and an open position in which the latter is released, and which is characterized by the fact that it comprises a heel piece having a sole-clamping element mounted movable under the action of the same elastic member in a longitudinal plane perpendicular to the plane of the ski, between a service position in which said element maintains the rear end of the sole of the boot on the ski and an open position in which the latter is released , the whole arranged so that the opening, respectively the closing, of the lateral jaws or of the sole-clamping element causes the opening, respectively the closing, of the element soleplate or side jaws.
  • this invention also relates to a ski boot intended to be fixed on a ski by means of the safety binding defined above, and which is characterized in that it comprises a sole having imprints cooperating in service position with the side jaws of the binding.
  • This binding fixed for example by screwing on the upper surface of a ski S, comprises two parts mechanically connected to each other, on the one hand a front device 1 for retaining the ski boot C in torsion and comprising in particular two lateral jaws 2, and on the other hand a rear device 3 for longitudinal retention (for front and rear falls) or heel piece, which in particular comprises a housing 4, in which is mounted an elastic member 5, and a lever actuation 6 also serving as a means of tightening the heel T of the boot C in the service position on the ski.
  • the two devices respectively front 1 and rear 3 are mechanically coupled, so that the elastic member 5 of energy accumulation actuates these two devices and that the opening, respectively closing, of one of the devices causes the opening, respectively closing, of the other device, and vice versa.
  • the front device 1 comprises two arms 7 carrying the jaws 2 and mounted pivoting each around a vertical pivot 8 so as to be able to move parallel to the surface of the ski S between a position closed service ( Figures 1 and 2), the jaws 2 by clamping in this position the side edges of the middle portion of the ski boot C, and an open position ( Figure 3) in which said boot is released.
  • the aforementioned displacement is caused by the action of the elastic member 5 of the heel piece 3 to which the arms 7 are connected by means of a rod 9 sliding longitudinally.
  • This rod 9 is connected to the arms 7 carrying the lateral jaws 2 by means of two pairs of rods 10, 11.

  • the rear or heel device 3 comprises a housing 4 fixed to the ski S in the walls of which is fixed a pin 22 on which the actuation lever 6 is pivotally mounted.
  • the heel piece 3 also comprises a spring case mounted pivoting about two transverse axes 23 fixed in the walls of the case 4, the spring case being formed of two parts 21, 24 sliding one inside the other so to act as a piston to compress the elastic member 5, here a helical spring, the force of the latter being adjustable by means of an adjustment screw 25 accessible from the rear of the heel piece 3.

  • the safety attachment also comprises a base plate 31 and a lateral guide element 32.
  • the base plate 31 is fixed, for example by screwing, to the upper surface of the ski S and is intended to serve as a housing for the mobile mechanical elements of the binding, in particular the arms 7 carrying the jaws, the actuating rod 9 and the two sets of articulation rods 10, 11, and to receive on its upper face the sole of the ski boot.
  • This base plate 31 has the particularity of presenting at its front end a deformable portion 31 'in cantilever and subjected to an elastic action tending to keep this portion parallel to the surface of the ski S.
  • l 'elastic action is exerted by two small helical springs 33, the space between the upper surface of the ski and the deformable portion 31' being further filled with a plastic foam 34, preferably with flexible closed cells, in order to avoid ice formation or the presence of snow or other materials in this space.

  • the lateral guide element 32 is formed by a transverse blade pivotally mounted on the base plate 31 by means of a screw 35 passing through its center, the ends of the blade being bent substantially vertically so as to form fins. centering.
  • the elastic member 5 exerts its force on the transverse axes 20 and 26, and consequently on the rod 19 by means of the rods 17 on the one hand and on lever 6 on the other hand.

  • the spring 5 is in its compressed position, while the axis 18 of the bent rods 17 is located in front of the fixed axes 27 of pivoting of these rods so that the rod 9 is also moved forward and thus causes the opening of the jaws 2 allowing the complete release of the shoe.
  • the complete release of the shoe C is further clearly facilitated by the feature described above of the base plate 31 which has at its front end an elastically deformable portion 31 '.
  • this portion 31 ′ can be deformed by crushing both longitudinally forward and transversely from one side or the other downward, thus providing the front of the shoe with a favorable sliding slope, friction and jamming between the sole and the base plate are very greatly reduced and the release of the shoe facilitated.

  • the binding according to the invention therefore allows a very significant reduction in the sum of the stresses undergone by the skier's leg during falls known as “combined front or rear with torsion by the fact that the different components of the opening forces torsion and falls in before for example, share the work of triggering a single retaining mechanism and no longer two as is the case with a classic binding with front stop and heel.
  • the forward fall forces causing the opening of the heel also lead to the opening of the jaws of the torsion restraint system, thereby reducing the torsional torque accordingly.
  • the binding according to the invention has the advantage, commercially, and also with a view to its use on rental skis, that the binding mechanism comprising three clamping zones, namely two lateral zones and one rear, allows the boot on the same binding installed on a ski of shoes of different sizes. Only the distance between the heel and the lateral jaws must be standardized and correspond to that between the heel and the lateral cleats of the sole of the shoes.
