Definitions

  • the invention relates to a method for the involuntary release of a ski boot held on a ski from the ski in the event of danger, in which the forces acting on the leg of the skier are measured continuously over time and in which the connection between the ski and the ski boot is released when that occurs the time integral formed from the measured forces, which represents a measure of the stress on the leg, reaches a trigger value which is above the static holding force of the ski binding.
  • the trigger value specified by the product of KraftxZeit is continuously compared with the time integral of at least one force acting on the leg, the time integral being continuously reduced to zero in accordance with a set time constant of the integration element becomes.
  • the safety ski binding is triggered when high forces act on the skier's leg for a short time or lower, but still dangerous, forces in the long term.
  • the value of each time integral formed is deleted when it falls below a certain minimum value of the stress. After each deletion of the integral, there is a reintegration when stress occurs, until the trigger value is reached or the stress has dropped below its certain minimum value.
  • the object of the invention is therefore to provide a method of the initially indicated type in which the power pulses on the skier's leg a g ewirk previously be taken into account when releasing the ski boot from the ski.
  • this object is achieved in that after force pulses which have not led to the triggering, the integral value is formed under the static triggering force and subtracted from the integral value above the static triggering force.
  • the integral value is reset in each case by subtracting the integral formed below the static triggering force. The leg is thus given a certain recovery time after a load. If new stresses occur during this recovery time, the trigger value is reached more quickly because the integral value that has not yet been completely reset is reintegrated.

Abstract

Par ce procede de declenchement d'une fixation de securite pour ski, les forces agissant sur la jambe du skieur, qui provoquent en cas de danger la separation entre le soulier et le ski, sont integrees dans le temps de facon continue. Lorsque l'integrale dans le temps de la force atteint une valeur seuil representee par le produit de la force par le temps, cette valeur seuil etant fixee au-dessus de la valeur seuil correspondante a l'integration de la force de retenue de la fixation, il y a separation entre le ski et le soulier. Pour eviter une addition d'impulsions, l'impulsion, qui n'a pas provoque le declenchement est annulee.

Claims (1)

  1. Procédé pour le déchaussage automatique d'un soulier de ski maintenu sur le ski dans lequel les forces agissant sur la jambe du skieur sont mesurées en continu et dans lequel la liaison entre le ski et le soulier de ski est interrompue lorsque l'intégrale du temps formée à partir des forces mesurées, qui constitue une mesure pour les sollicitations de la jambe, atteint une valeur de déchaussage se situant au-dessus de la force de retenue statique de la fixation de ski, caractérisé en ce que, après les impulsions de forces n'ayant pas conduit au déchaussage, la valeur de l'intégrale est formée au-dessous de la force statique de déchaussage et déduite de la valeur de l'intégrale au-dessus de la force statique de déchaussage.
