  • the automatic heel unit further comprises a radial bearing, by means of which the heel holder is pivotably mounted on the base unit about a substantially vertically oriented, geometrical pivot axis relative to the base unit and thus can be pivoted away from its holding position, starting from its holding position along an adjustment path about the pivot axis
  • Radial bearing has a pin which is formed on a first of the two units of base unit and heel holder, and the radial bearing has a receptacle which is formed on a second of the two units of base unit and heel holder, wherein the pin is rotatably inserted into the receptacle, whereby the heel holder is pivotally mounted about the pivot axis relative to the base unit to the base unit.
  • the heel unit comprises a pretensioning device, by means of which the heel holder can be prestressed to its holding position in a first region of the adjustment path, wherein the pretensioning device comprises a push element with a positioning structure and an elastic element, wherein the push element bears against the push button by a force generated by the elastic element Pin is depressible, whereby the positioning structure is pressed against a counter-structure associated with the pin, when the heel holder is in the first region of the adjustment, to bias the heel holder in the first region of the adjustment to its holding position.
  • the pretensioning device comprises a push element with a positioning structure and an elastic element, wherein the push element bears against the push button by a force generated by the elastic element Pin is depressible, whereby the positioning structure is pressed against a counter-structure associated with the pin, when the heel holder is in the first region of the adjustment, to bias the heel holder in the first region of the adjustment to its holding position.
  • Heel machines of the technical field mentioned above are known. Their task is to ensure a reliable fixation of the heel area of the ski boot on the ski in a holding configuration.
  • some such heel machines also allow, starting from the holding configuration, a safety release in which the heel area of the ski boot is released. This may be, for example, a safety release in the forward direction or a lateral safety release.
  • the term "safety release” means that the automatic heel releases the heel area of the ski boot if the energy of a shock on the ski boot, the ski binding or the ski exceeds a predetermined value. It is irrelevant whether the heel unit is in the holding configuration or in another configuration after the ski boot is released. For bumps whose energy does not exceed this value, the heel unit remains in the hold configuration and continues to lock the heel area of the ski boot in a lowered position towards the ski.
  • ski binding to which the heel machine belongs should fulfill.
  • downhill ski bindings are only used for downhill skiing and downhill skiing at ski lifts.
  • touring ski bindings are also used for walking on skis, in particular for ascending with the help of climbing skins attached to the skis.
  • Cross-country skiing is used for cross-country skiing and telemark bindings for skiing with telemark technique.
  • downhill ski bindings have only to ensure a reliable fixation of the ski boot on the ski in a so-called stop position.
  • Some heel machines also have a so-called entry-level configuration or deployment configuration, in which they allow entry into the ski binding.
  • This function can also be taken over by a front-end automaton.
  • cross-country and Telemarkitatien usually have to hold the ski only pivotable about an axis aligned in the ski direction axis and to allow entry into the ski binding.
  • touring ski bindings such as downhill ski bindings must be reliable Ensure fixation of the ski boot on the ski in the holding position and allow entry into the ski binding. In addition, however, they must be able to keep the ski boot pivotable about an axis oriented in the direction of the ski for walking on skis or for ascent.
  • touring ski bindings have a walking position in which the ski boot is pivotable about an axis oriented in the direction of the ski and pivotable in the heel area of the ski, as in cross-country skiing and telemark binding, whereby a joint movement between the ski boot and the ski is made possible for walking.
  • the heel counter may be in different configurations in the walking position of a touring ski binding, depending on the construction and type of touring ski binding. For example, it may be in its holding configuration, in an entry-level configuration, in a trip configuration, or in a walking configuration.
  • an heel automat is additionally required with such a cross-country or telemark binding, by means of which the ski boot can be lowered in its heel area towards the ski, and which the heel area of the ski boot can walk can release in the walking position of cross-country or telemark binding.
  • Touring ski bindings are basically subdividable into two types.
  • One type comprises a ski boot carrier which can be pivoted relative to the ski and to which the ski boot is held by binding jaws.
  • a representative member of this type of touring ski bindings is, for example, in EP 0 754 079 B1 (Fritschi AG).
  • the second type relies on ski boots with stiff soles.
  • the ski boot is pivotally mounted in his toe area in a skim-mounted front automat.
  • the automatic heel unit is also fixedly mounted in a distance from the front automatic machine on the ski adapted to a ski boot sole length and, in the downhill position of the binding, holds the ski boot in the heel area in a lowered position.
  • Suitable for this type of binding ski boots typically have two lateral recesses for pivotal mounting in the front vending machine in the toe box. Next, they have in the heel area to the rear open recesses into which holding means of the heel unit can intervene.
  • ski longitudinal direction means along the orientation of the longitudinal axis of the ski.
  • skiparallel means aligned for an elongate object along the longitudinal axis of the ski.
  • ski-parallel means aligned parallel to the sliding surface of the ski.
  • ski direction means a direction transverse to the ski longitudinal direction, which, however, need not be oriented exactly at right angles to the longitudinal axis of the ski. Their orientation may also be slightly different from a right angle.
  • ski center means a center of the ski in the ski direction
  • ski manifest does not mean that it can move in relation to the ski.
  • ski refers to the reference system of (fictitious) skis.
  • front, “rear”, “top”, “bottom” and “side” refer to “front”, “rear”, “top”, “bottom” and “side” of the ski.
  • horizontal and vertical refer to the ski, with “horizontal” lying in a ski-parallel plane and “vertical” oriented perpendicular to this plane.
  • a touring ski binding of the above introduced second type is in the EP 0 199 098 A2 (Barthel) and is sold under the name Dynafit.
  • a front-end machine This system has two clamping parts, each with a pin aligned in the direction of the ski, which engage in recesses in the toe area of the ski boot when entering the touring ski binding from the sides. As a result, the pins form a pivot bearing of the ski boot, on which the ski boot can be pivoted relative to the ski about an axis oriented horizontally in the ski direction.
  • a separate from the front automatic heel machine this system has a base member for attachment to a ski and a heel holder for holding the ski boot in the heel area of the ski boot.
  • the heel holder is mounted on a base element arranged on the vertically oriented pin and thereby mounted about a vertically oriented, geometric pivot axis relative to the base member pivotally mounted on the base member.
  • the heel holder In the holding configuration of the heel unit, the heel holder is in a holding position. In this holding position, two pins arranged on the heel holder are oriented forwards towards the front automatic machine, whereby they engage in recesses in the heel of the ski boot and thereby can lock the ski boot in a lowered position towards the ski.
  • the heel of the ski boot is lowered from above onto the pins of the heel holder. Since the recesses in the heel of the ski boot downwards are largely open, thereby the recesses are guided over the pins, whereupon the pins engage in locking recesses in the recesses for locking.
  • both pins can be pressed apart against a spring force, allowing them to slide out of the detent recesses and the recesses and release the heel of the ski boot upwards.
  • both pins are each arranged on a lever, wherein the levers are each mounted in a horizontal plane pivotally mounted on the heel holder. Both levers are biased by a spring force, so that the two pins are pressed towards each other.
  • the heel unit In addition to the safety release in the forward direction, the heel unit also enables lateral safety release.
  • the heel holder can be pivoted about a vertically oriented, geometric pivot axis against a spring force on both sides until the two pins are pivoted away to the side and the heel area of the ski boot is released to the appropriate page.
  • the pin of the base member on its rear side on a flat surface, which is aligned with its normal vector horizontally backwards. A mounted in the heel holder and biased forward with a spring piston is pressed in the holding position against this surface of the pin.
  • An heel automat according to EP 0 199 098 A2 can also be brought into a climbing position by the heel holder by the skier as in a lateral safety release is rotated about the pivot axis until the two pins are pivoted to the side of the trajectory of the heel of the ski boot.
  • the heel holder has a plurality of rotational positions in which the pins are pivoted out of the path of movement of the heel. These individual rotational positions are each predetermined by a spring catch for locking the heel holder. When the heel holder is in one of these rotational positions, the trajectory of the heel of the ski boot is free and the ski boot can be lowered down to the ski.
  • a support arranged on the heel holder is pivoted at a certain distance from the ski into the path of movement of the heel of the ski boot. Any such support prevents the ski boot from being at a different distance from the ski on lowering to the ski. Accordingly, different climbing aids can be adjusted by positioning the heel holder in the different rotational positions.
