  • the restoring force that the spring opposes to the displacement of the jaw is lowered to the side where the knee is most fragile, or it is increased on the side where the knee is most resistant.
  • this restoring force increases for both direction of rotation, like EP 674 925, but it increases more side where the knee is strongest.
  • the retaining element is more efficient and safer insofar as it allows to move back momentarily, according to the variations of support of the shoe, the shoe release threshold, but where the release threshold is momentarily higher on the side where the skier's knee is more resistant.

Any suitable means of joining is suitable.
  • connection between the drawer element 38 and the transmission plate 36 is a push link, i.e. a link which allows the transmission of forces longitudinal in the longitudinal direction of sliding of the drawer 38. preferably, as illustrated, the link also allows pivoting angle of the transmission plate.

  • the pad 50 At rest, i.e. in the absence of forward movement of the plate transmission 36, the pad 50 is set back forward with respect to the foot 55 of the link from a distance at least equal to the maximum stroke of displacement of the tie rod when the wing 6 is opened. This is shown in the figure. 7.
  • a stop formed for example by the bottom 58 of the housing of the drawer element 38 limits the stroke of this element in a position where its stud 50 just comes into contact with the foot 55 of the link, while the wing 6 is in closed rest position. This is illustrated in Figure 8.
  • the wing return 6a causes the rearward intermediate piece and the head of the tie rod.
  • the link 51 also moves towards the rear.
  • the intermediate piece In the absence of intense support on the support plate 23, that is to say in the retracted position of the transmission plate 36, the intermediate piece is in stop against stop 54 of the head of the tie rod.

  • Any suitable means of locating retaining elements or skis or any coding means is suitable for the shoes to be associated with good restraints.
  • the retaining wing located on the inside of the ski where this intense support product, has an opening resistance force which is increased by compared to the other wing, due to the depression of the plate 23 and the advancement transmission plate 36 and drawer 38.
  • This is advantageous because the skier can use their skis more, while driving, by reducing the risk of untimely triggering of the ski which it requests the inner wing.
  • the skier lowers the hardness of the elements of restraint, i.e. decreases the stress threshold beyond which the restraint releases the shoe, knowing that in the driving phases, by its rear support, it temporarily increases the hardness of the inner wings of its retainers.

  • FIG. 13 illustrates another variant implementation of the invention.
  • the effect of the drawer element on the link (s) is neutralized in the case where the front of the shoe tends to urge the jaw upwards.
  • This configuration corresponds for example to a fall towards the rear of the skier.

This element is the same type as the drawer element 38 previous, and, like the previous element, it is intended to be pushed back to the front in case of variation in the support of the skier's shoe on a feeler. In being pushed forward, the drawer element 91 moves the rod 90, and places its front face substantially in the extension of the bearing face of the flat 86.
