  • Heel units of this type are known in particular as part of ski touring bindings in which a ski touring boot is held on a front unit of the binding so that it can pivot about an axis of rotation running transversely to the longitudinal axis of the gliding board.
  • a heel unit of the type mentioned is arranged, which holds the ski touring boot in the downhill position so that it is fixed to the ski and releases the ski touring boot in the walking position so that it can lift off the gliding board while walking.
  • a climbing aid is used to compensate for changing gradients in the terrain when walking. Steep terrain can be compensated for by switching on the climbing aid and thus increasing the contact surface over the gliding board for a heel section of the ski touring boot.
  • one or two climbing aids are usually provided, so that in addition to an optionally provided, so-called zero position, in which no climbing aid is switched on and the heel section of the ski touring boot rests directly on the gliding board, the base or a brake pedal of the heel unit, one or two further, in particular different support heights can be set by the respective climbing aid being adjusted or switched on by the user.

  • the climbing aid 40 can include a recess 46 which is designed to engage with a ski pole tip.
  • the cutout 46 is designed as a through hole 46 .
  • Such a recess 46 can be provided at any point of the climbing aid 40 which a user of the heel unit 10 can reach with a ski pole tip, so that the user can insert the ski pole tip into the recess 46 and with his ski pole via the climbing aid mounted on the binding body 32 40, the binding body 32 can rotate to adjust between the first and second rotational position.
  • the binding body 32 is shown in the second rotational position.
  • the heel unit 10 is consequently in the walking position, regardless of the position of the climbing aid 40, since the coupling pins 18l, 18r do not point forwards in the direction of the gliding board shoe and therefore cannot engage therewith either.
  • FIGs 6 and 7 12 are perspective views of heel assembly 10 showing heel heel 40 in the second/inactive position ( figure 6 ) or pivoted about the climbing aid pivot axis S, in the first/active position ( figure 7 ) show.
  • the heel section of the gliding board shoe can rest on a base 24 provided on the base 12, in particular on the second base element 22, at a relatively low height h0 (cf. figures 4 and 9 ) are supported above the gliding board level E.
  • This setting i.e. the binding body 32 in the second rotational position and the climbing aid 40 in the second/inactive position, can be used in particular when walking on flat or only slightly steep terrain in order to give the user the best possible Provide neutral shoe position over the gliding board. In this so-called zero position, it is also possible to increase the stride length.
  • FIG 7 a plan view of the heel unit 10, in which the climbing aid 40 is shown in the active position, it can be seen that the heel section of the gliding board shoe can be supported during a walking movement on the second support section 44A, which is arranged on the second arm section 44 of the climbing aid 40 is.
  • figure 9 12 is a front view of heel unit 10 showing various heights h0, h1, and h2 of support on pedestal 24 of base 12, on first support portion 42A, and on second support portion 44A. It can be seen that in the present exemplary embodiment, depending on the slope of the terrain and the personal preference of the user, a relatively low support height h0 on the base 24 (cf. figure 6 ) and, in addition, a relatively high support height h2 can be set on the second support section 44A of the climbing aid 40 if the climbing aid 40, as in figure 9 shown, is pivoted about the climbing aid pivot axis S into its active position. The user can therefore bring the binding body 32 into the second rotational position for ascent with the heel unit 10 and then choose between two different support heights h0, h2.
  • the present invention offers the user the option of pivoting the climbing aid 40 from the inactive/second position into the active/first position even when the binding body 32 is in the first rotational position, i.e. the heel unit 10 is in the actual downhill position , in order to be able to ascend with the touring binding.
  • the first arm section 42 of the one-piece climbing aid 40 can cover the coupling pins 18l, 18r when the climbing aid 40 is in the active position, so that the heel unit 10, in particular the coupling pins 18l, 18r, can no longer engage with the gliding board shoe in order to hold it in place and the first support portion 42A of the first arm portion 42 supports the heel portion of the gliding board shoe at the height h1 above the plane E of the gliding board.
  • the support height h1 can in particular be greater than the support height h0 and less than the support height h2.
  • the user can thus choose between three different support heights h0, h1, h2 above the gliding board plane E for the heel section of his gliding board shoe, with a relatively low support height h0 and a relatively high support height h2 being set in the second rotational position of the binding body 32 and an average support height h1 between the relatively low support height h0 and the relatively high support height h2 can be set in the first rotational position of the binding body 32 without the binding body 32 having to be rotated for the ascent.
  • the support height h1 is greater than or equal to the second support height h2. This results in many different specific implementation options for the present invention, which is explicitly not limited to the first exemplary embodiment described above.
