  • the connection plates 33, 34 can be used to mount the heel holder 1 with the contact plate 32 on a ski under the Grip the base structure 2 so that through-openings in the connecting plates 33, 34 are aligned with through-openings in the base structure 2.
  • the base structure 2 and the support frame 32 can then be connected to the ski by means of the screws 35 in such a way that they can no longer be moved relative to one another.

  • the adjusting screw 80 includes a screw head 80c supported by a support member 80e, having an engagement structure 80d for a tool, and a screw shank having a threaded portion 80a with a free end 80b.
  • a nut 81 screwed onto the threaded portion 80a is also disposed in the cage 64 and has a shape that prevents the nut 81 in the cage 64 from rotating.
  • the nut 81 is pressed by the push-on spring 21 against an end face of the cage 64 facing the screw head 80c, so that turning the adjusting screw 80 in the nut 81 causes a linear movement of the first housing part 3 relative to the base structure 2, for example to attach the ski binding adapt to different ski boot sizes.
  • the length of the evasive movement of the heel holder 1 in the case of a ski flex and the force required for this are defined by the start-up spring 21 .
  • the adjusting screw 80 can have an extension at its end remote from the screw head 80c, which engages in the starter spring 21 .
  • the lengthening helps in that the push-on spring 21 is evenly compressed under pressure and does not, for example, buckle.
  • a free end 80d of the extension can be connected to a securing element 82 which, like the nut 81, cannot twist relative to the separate functional element 6 and also the base structure 2 and preferably also cannot tilt.
  • the free end 80d that is, a cross section of the free end 80d, has a non-round shape; in the exemplary embodiment, the cross section is square.
  • the securing element 82 can be, for example, a clip with an opening which can receive the free end 80d of the adjustment screw 80 at least in a relative position of the opening to the free end 80d, but which has a cross section which is different than the cross-section of the free end 80d. This advantageously prevents the free end 80d of the adjusting screw 80 received in the opening from being able to rotate unintentionally in the opening. On the other hand, turning the adjusting screw 80 and the free end 80d the set screw 80 within the opening of the fuse element using the tool.
  • the securing element 82 can be formed from an elastically deformable sheet metal, such as a spring sheet metal.
  • the free end 80d of the adjustment screw 80 can then overcome resistance of the opening of the fuse element, for example elastically deforming the opening or areas at the periphery of the opening.
  • the relaxation of these elastic deformations can produce a perceptible sound so that the user can get positive confirmation that the adjustment screw 80 has rotated in the locking element 82 .
  • the path of the adjusting screw 80 per revolution and partial revolution is known via the thread pitch, the length of the adjustment of the heel holder housing 3, 4 on the base structure 2 can be deduced from the number of audible clicks. This means that it can be specified for the user, for example, that adjusting the binding by half a shoe size requires turning the adjustment screw 80 by a defined number x audible clicks.
  • the figure 2 shows in two views (a), (b) a section through the assembled heel holder 1 of FIG figure 1 along the central longitudinal axis of the binding, mounted on a ski, not shown.

  • the upper side of the shoulder on the connecting element 63 facing the counter-shoulder in the opening 43 are spaced apart by a distance a, which is also important when the heel holder 1 is released laterally, since it determines the length of a movement of the second housing part 4 relative to the first housing part 3 along the Axis of rotation A limited.
