Definitions

  • the present invention relates to a heel unit of a gliding board binding comprising a base portion for mounting the heel unit on a gliding board, two juxtaposed pin portions whose ends project in a forward direction, wherein at least one abutment zone is arranged on the pin portions which contacts in a state of use of the heel unit is with a heel portion of a Gleitbrettschuhs or with a pin portions holding pin bearing of the heel unit.
  • Heel units are known as part of a gliding board binding for mounting on a gliding board, especially a ski, splitboard or snowshoe.

  • the scenery is shaped so that the pin sections are istspreitzt from each other, ie must move laterally away from each other to leave the recess of the ski boot. This spreading movement opposes the elastic force of the U-shaped yoke and the resilience of the stiffening bearing that holds the yoke. This results in a force acting on a further contact zone of the pin portions which extend at inner peripheral portions of the ends of the pins.

It can thereby be achieved that the forces acting on the respective pin portion when using the heel unit from the sliding board shoe or from the pin bearing are introduced into the pin portion over a larger surface area, namely beyond the substantially flat surface of the contact zone, and thus the Surface-related force is reduced to or from the pin portion.
