Definitions

  • the invention relates to an automatic heel unit for a ski binding, comprising a jaw for holding a ski boot in a heel region of the ski boot, a jaw carrier, on which the jaw is movably mounted, and an elastic element.
  • the automatic heel has a holding configuration in which the jaw is in a holding position and can interact with the heel region of the ski boot held in the ski binding in such a way that the ski boot is locked in a lowered position.
  • the automatic heel unit has a triggering configuration in which the jaw is in a release position and the heel area of the ski boot is released from the jaw.
  • the jaw is movable from its holding position to its release position and back in an adjustment relative to the jaw carrier, wherein the adjustment path has a first region in which the jaw is stretched by the elastic member with a force to its holding position.
  • Heel machines of ski bindings have the task of ensuring a reliable fixation of the heel area of the ski boot on the ski in a holding configuration. They also have the task of releasing the heel area of the ski boot in a release position, at least for an entry into the ski binding and for an exit from the ski binding.
  • the heel machines can also provide 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 keeps the heel area of the ski boot locked even in the event of bumps acting on the ski boot, the ski binding or the ski in the lowered position as long as the energy of the bumps does not exceed a predetermined value , However, if the energy of a shock exceeds this predetermined value, the heel machine releases the heel area of the ski boot. It is irrelevant whether the automatic heel is after the release of the ski boot in the release position or not.
  • the type of tasks to be performed by a heel automaton usually depends on what function the ski binding to which the heel machine belongs is intended to 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 Telemarkbindurigen 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 holding configuration.
  • cross-country and telemark bindings usually have to keep the ski only pivotable about an axis aligned in the ski direction axis.
  • touring ski bindings must have both a holding configuration and, in addition, an ascending climb configuration.
  • a climb configuration is the ski boot, as in cross-country skiing and telemark binding, is pivotable about an axis oriented in the direction of the ski and can be lifted off the ski in the heel area, whereby a joint movement between the ski boot and the ski is made possible for walking.
  • an automatic heel strap is additionally required, by means of which the ski boot can be lowered in its heel area towards the ski, and which can release the heel area of the ski boot for walking in the ascent configuration.
  • Touring ski bindings in turn are subdivided into three types.
  • the first type of touring ski bindings comprises a ski boot carrier to which the ski boot is held by binding jaws. In the ascending configuration, the ski boot carrier with the ski boot held therein can be pivoted relative to the ski. In the holding configuration, however, the ski boot carrier is in a substantially ski-parallel. Locked alignment, whereby the ski boot held on the ski boot is fixed accordingly.
  • a representative member of this type of touring ski bindings is, for example, in WO 96/23559 A1 (Fritschi AG Apparatebau).
  • the second type of touring ski bindings 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 firmly attached to the ski in a distance from the front automatic machine adapted to a ski boot sole length and locks the ski boot in the heel area in the holding configuration.
  • the heel of the ski boot is released from the heel counter, so that the ski boot can be lifted off the ski and swiveled around the storage on the front automat.
  • a representative member of this type of touring ski bindings is, for example, in EP 2 762 209 A2 (Marker Germany GmbH).
  • the third type of touring ski bindings like the first type, includes a ski boot carrier on which the ski boot is held in the ascent configuration.
  • a binding jaws is provided on the front of the ski boot carrier, while only one retaining element is provided on the rear of the ski boot carrier.
  • a rear binding jaw which can fix the heel of the ski boot in the holding configuration on the ski, is not arranged on the ski boot carrier, but directly on the ski. Therefore, the ski boot is at this third type of touring ski bindings in the ascent configuration by the front binding jaw and the holding member fixed to the ski boot carrier, while being held in the holding configuration by the front and the rear binding jaws with its sole substantially skiparallel aligned.
  • a representative member of this type of touring ski bindings is, for example, in CH 706 664 A1 (Frifschli AG - Swiss Bindings).
  • heel machines which have a holding configuration and a release configuration, are required for downhill ties and for touring ski bindings and possibly also for cross-country or telemark bindings.
  • a heel piece which belongs to the technical field mentioned above, is in the WO 96/23559 A1 (Fritschi AG Apparatebau).
  • This automatic heel comprises a jaw, which is in the holding configuration of the heel unit in a holding position and the sole of the ski boot in the heel area above and laterally reaches slightly forward to support the ski boot upwards and sideways. As a result, the ski boot is locked in a lowered position.
  • the heel area of the ski boot is released from the jaw.
  • the jaw is movable from its holding position to its release position and back on an adjustment relative to a jaw carrier. Starting from the holding position of the baking leads, this adjustment first vertically upwards.
  • this automatic heel is not designed very compact.
  • its design requires a larger and more solid construction if it is to be able to absorb a large amount of energy in the event of a collision with the ski boot, the ski binding or the ski before a safety release occurs.
  • its construction requires an even larger and more massive construction if it is to be able to fulfill further tasks which, as mentioned above, require some types of ski binding.
  • ski binding systems For the description of ski binding systems, a (fictitious) ski is often used as the reference system, assuming that the binding is mounted on this ski. This habit is taken over in the present text.
  • 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 the (fictional) ski.
  • 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.
  • the object of the invention is to provide a the aforementioned technical field belonging heel machines, which is compactly constructed.
  • the solution of the problem is defined by the features of claim 1.
  • According to the invention is at each position of the baking in the first region of the adjustment of the elastic element generated to tension the baking to its holding position at an acute angle to an orientation of the adjustment at the respective position of the jaw aligned. It is irrelevant whether the first region of the adjustment assumes a contiguous portion of the adjustment, two or more separate sections of the adjustment or the entire adjustment.
  • the adjustment path is preferably linear. This means that the center of gravity of the jaw is moved relative to the jaw carrier when the jaw is moved within the first range of the displacement relative to the jaw carrier. Whether the first region of the adjustment path is straight or curved or has both rectilinear and curved sections is irrelevant. It is also irrelevant whether the course of the adjustment travel within the first range of the adjustment travel is considered as the course of the distance traveled by the center of gravity of the jaw relative to the jaw carrier or as the course of the path traveled by another reference point or reference region of the jaw relative to the jaw carrier. Regardless, the first portion of the adjustment path may be straight or curved.
  • the alignment of the adjustment path at a certain position of the jaw within the first range of the adjustment corresponds to a tangent which is applied to the adjustment path at the position of the jaw.
  • the position of the reference point or reference area considered for determining the course of the first range of the adjustment path in the first range of the adjustment path is to be regarded as the position of the jaw in the first range of the adjustment path.
  • the orientation of the adjustment path does not depend on whether the jaw retains its orientation relative to the jaw carrier during a movement along the first region of the adjustment path or changes due to a rotational movement relative to the jaw carrier.
  • the orientation of the first range of travel will depend on the position at which the shoe is in the first range of travel. Conversely, if the first range of travel is linear and straight, the alignment of the first range of travel at all possible positions of the jaw remains the same.
  • the force for tensioning the jaw to its holding position generated by the elastic element may change its orientation depending on the position of the jaw in the first range of the adjustment.
  • the force generated by the elastic element for the voltage of the baking to its holding position can also be independent of the position of the baking in the first region of the adjustment.
  • the force generated by the elastic element can be transmitted to the clamping of the baking to its holding position directly or indirectly on the jaws. In this case, the force ultimately acting on the jaws can be aligned in a same direction as the force generated by the elastic element. But the force generated by the elastic element can also be deflected so that the force ultimately acting on the jaws in a different direction than the force generated by the elastic element.
  • the jaw tensioning force generated by the elastic element is not aligned parallel to the orientation of the travel at that jaw position and always at an acute angle, i. oriented at an angle of more than 0 ° and less than 90 ° to the orientation of the adjustment path at this position.
  • the angle between the force and the orientation of the adjustment is the smallest angle between the direction in which the force acts and the given by the tangent and thus by a straight line alignment of the adjustment.
  • the solution according to the invention has the advantage that the elastic element generates its force at an acute angle to the orientation of the first region of the adjustment path. Accordingly, the elastic element can be aligned at an acute angle to the first region of the adjustment. As a result, the device with which the movement of the baking is made possible on the adjustment relative to the jaw carrier, best possible be separated from the elastic element. Therefore, this device can be constructed more compactly. In addition, if necessary, a larger elastic element can be used without the whole heel automat would have to be built significantly larger and more massive. If the automatic heel unit allows a safety release, therefore, if necessary, with a compact designed heel unit in case of a shock to the ski boot, the ski binding or The ski will receive more energy before a safety release occurs. Accordingly, it allows the skier a sportier driving style, as it is used for example in the freeride area.
  • the jaw is designed such that it can embrace the sole of the ski boot in the heel area above and laterally reaching somewhat forward.
  • This has the advantage that the jaw can prevent the heel area of the ski boot in the holding configuration of the heel unit from moving freely upwards or laterally, thereby locking the heel area of the ski boot in the lowered position in a simple manner. It is irrelevant whether the baking is made in one piece or several pieces.
  • the jaw can also grip the rear end of the ski boot sole in the heel area of the ski boot only at the top or only laterally to the front. It is also irrelevant whether the jaw is made in one piece or several pieces.
  • the jaw may also comprise one or more elements which may engage in one or more recesses in the heel region of the ski boot.
  • This can also be achieved that the heel area of the ski boot can be locked in the holding configuration of the heel unit in a simple manner in the lowered position. To achieve this advantage, it is irrelevant whether the jaw is made in one piece or in several pieces.
  • the baking on a shell shape has the advantage that the jaw in a simple manner, the sole of the ski boot in the heel area above and laterally reaching slightly forward to prevent the heel area of the ski boot at a free movement upwards or in the lateral direction and thereby the heel area of the ski boot in the lowered position. It is irrelevant whether the baking is made in one piece or several pieces.
  • the heel unit allows a safety release.
  • This has the advantage of increasing safety for the skier.
  • the automatic heel unit enables a safety release in the forward direction.
  • the automatic heel unit allows lateral safety release.
  • the automatic heel unit allows both a safety release in the forward direction and a lateral safety release.
  • the jaw in the first region of the adjustment is preferably biased by the elastic member with a force to its holding position.
  • This has the advantage, irrespective of the type of safety release, that an optimally controlled safety release can be made possible by constructing the automatic heel so that the jaw must first be moved against the force generated by the prestressed elastic element along the first range of the displacement until it comes to a safety release.
  • the bias of the elastic element is adjustable. This makes it possible to adjust the energy that can be absorbed by the heel counter in the event of a collision with the ski boot, the ski binding or the ski, before a safety release is triggered. In a variant of this, however, the bias of the elastic element is not adjustable. This makes the heel automat easier to construct.
  • the jaw in the first region of the adjustment is not biased by the elastic element with a force towards its holding position.
  • the force generated by the elastic element for tensioning the jaw to its holding position at an angle in an area of 20 ° to 70 °, preferably in a range of 40 ° to 70 °, especially preferably aligned in a range of 50 ° to 70 ° to align the adjustment at the respective position of the jaw.
  • the automatic heel comprises a guide device, by which the jaw along the displacement relative to the jaw carrier from its holding position to its release position and is movably mounted back.
  • a guide device by which the jaw along the displacement relative to the jaw carrier from its holding position to its release position and is movably mounted back.
  • the heel machine may not include such a guide means.
  • this can have the advantage that the heel piece can be built more easily.
  • the guide device is preferably a forced control of the baking.
  • the jaw is stably movably mounted along the adjustment path relative to the jaw carrier. Accordingly, the ride comfort and safety for the skier can be increased.
  • this makes it possible that the force generated by the elastic element, which acts directly or indirectly and possibly deflected on the jaws, even at an angle of more than 0 ° to align the adjustment at the respective position of the jaw aligned on the jaws can act because the jaw is held securely by the positive control on the adjustment.
  • This has the advantage that the construction of the Heel counter can be simplified.
  • this has the advantage that the force generated by the elastic element can be transmitted understood on the jaws.
  • the area of the elastic member which transmits the force generated by the elastic member for baking lays back a shorter distance than the jaw when the jaw is moved along the first range of the displacement.
  • This is particularly advantageous when the jaw is biased in the first region of the adjustment to its holding position and is in the holding position in the first region of the adjustment.
  • the jaw can already be stretched optimally back to the holding position with a slight movement away from its holding position, because the elastic element already generates a large force at the beginning of the movement in order to tension the jaws towards its holding position. This increases ride comfort and safety for the skier. In particular, this can also be optimized at most by the automatic heel safety release enabled.
  • the guide device is not a forced control of the baking.
  • the jaw is advantageously mounted by the guide means along the displacement relative to the jaw carrier from its holding position to its release position and displaced back. This has the advantage that in a simple way a forced control of the baking can be achieved. It does not matter whether the jaw in addition to a translational movement also performs a rotational movement or not.
  • the jaw is pivotally supported by the guide device along the adjustment path relative to the jaw carrier from its holding position to its release position and back about a pivot axis.
  • the jaw is differently supported by the guide means along the displacement relative to the jaw carrier from its holding position to its release position and movable back.

This has the advantage that the force of the elastic element can be optimally transferred to the jaws. If the automatic heel unit therefore enables a safety release, the effective range also increases the reliability of the safety release.
  • the power transmission from the elastic element to the jaws takes place indirectly via at least one intermediate element.
  • this intermediate element may be a piston, by which at each position of the jaw in the first region of the adjustment, the force generated by the elastic element for tensioning the baking to its holding position directly or indirectly to the effective range of the baking and thus on the jaws is transmitted.
  • the intermediate element is an intermediate element other than a piston or that another intermediate element is provided in addition to the piston.
  • This other or further intermediate element may for example be a pawl, ie a lever pivotably mounted about an axis.
  • Such a pawl for example, mounted pivotably about an axis on the jaw carrier and between the effective range of the jaw and the elastic member or the possibly existing piston be arranged, which generated by the pawl at each position of the jaw in the first region of the adjustment of the elastic element Force is transferred to the voltage of the baking to its holding position on the effective range of the baking and thus on the jaws.

In this case, the ratio or reduction can be adjusted depending on the position of the baking within the first range of the adjustment. This allows a modification of the course of the force acting on the jaws in comparison to the course of the force generated by the elastic element.

  • ski binding with the heel is not a touring ski binding, but a different kind of ski binding.
  • a ski comprises a ski binding with an inventive heel counter.
  • FIG. 1 shows an oblique view of an inventive heel unit 1 in the holding configuration.
  • a line running horizontally from front to back in the longitudinal direction through the automatic heel unit 1 runs in the figure from bottom left to top right. This line runs parallel to the ski longitudinal direction of a ski, not shown here, on which the automatic heel unit 1 can be mounted.
  • In the figure at the bottom left corresponds to the heel machine 1 front.
  • the automatic heel unit 1 comprises a jaw 2 for holding a ski boot, not shown here, in the heel region of the ski boot, a back support 3, a base element 4 and an opening lever 5.
  • the base element 4 can be mounted on a ski by being bolted to the ski, for example.
  • the jaw carrier 3 is arranged, while the jaws 2 is mounted on the jaw carrier 3 and can be moved by a movement of the opening lever 5 from a holding position to a release position and back on a displacement relative to the jaw carrier 3.
  • the jaw 2 is in the holding position. In this holding position, the jaw 2 can lock the heel area of a ski boot held in the ski binding in a lowered position.
  • FIG. 2 shows an oblique view of a vertically oriented, running in the longitudinal direction section through the heel unit 1 in the holding configuration.
  • the jaw 2 is mounted on the jaw carrier 3 with a lower rod 10 oriented horizontally in the transverse direction and an upper rod 11 aligned horizontally in the transverse direction.
  • the lower rod 10 is aligned horizontally in Skiquerides and passes through a vertically aligned slot 12 in the jaw carrier 3 (see FIG. 3 ).
  • This elongated hole 12 forms a vertically oriented positive guide for the lower rod 10.
  • This notch 13 forms a vertical positive guidance for the upper rod 11.
  • the notch 13 limits movement of the upper bar 11 only downwards.
  • the limitation of the movement of the lower rod 10 upwardly through the slot 12, however, requires that the jaw 2 can only be raised just so far up until the upper rod 11 is just lifted out of the notch 13 and along one to the upper rear edge the groove 13 subsequent groove 14 can be moved backwards down.
  • the automatic heel unit 1 is shown in the holding configuration and thus the jaws 2 in its holding position.
  • the lower bar 10 of the jaw 2 is at the lower end of the slot 12 and the upper bar 11 of the jaw 2 at the lower end of the notch 13.
  • the jaw 2 is lifted upwards , In this case, the jaw 2 is due to the leadership of the lower and upper bars 10, 11 first moved without rotational movement upwards. Only when the lower rod 10 is moved to the upper end of the slot 12, the upper rod 11 is lifted over the rear upper edge of the notch 13. Only then can the baking 2 are tilted with its upper portion to the rear in its release position by the upper bar 11 of the groove 14 is moved along backwards down.
  • a block 15 with a trapezoidal cross-section about the longitudinal axis of the lower rod 10 is rotatably mounted on the lower rod 10.
  • This block 15 has a forwardly facing surface whose normal is aligned horizontally facing forward. With this surface, the block 15 is supported against a front inner wall of the jaw carrier 3, so that the block 15 can not rotate freely about the lower rod 10.
  • the block 15 has a rearwardly facing surface, the normal is tilted with respect to a horizontal by 30 ° upwards.
  • the jaw carrier 3 has in its rear region a recess with a circular cross-section. A longitudinal axis of this recess is seen from the rear to the front by 30 ° down.
  • a piston 16 is movably mounted, which rests with its front side on the rearwardly facing surface of the block 15.
  • a spring 17 is inserted as an elastic element. This spring 17 is supported with its front end against the piston 16. With its rear end, the spring 17 is supported against a threaded sleeve 18, which is screwed with its thread in the recess in the jaw carrier 3.
  • the bias of the spring 17 can be adjusted by the threaded sleeve 18 is screwed more or less far into the recess in the jaw carrier 3. Due to the bias of the spring 17 and the vertical positive guidance of the jaw 2 on the jaw carrier 3 of the jaws 2 is thereby pressed down.
  • the force with which the jaw 2 is pressed down is half as large as that generated by the spring 17 Force.
  • the piston 16 has a forwardly directed active surface, which is oriented perpendicular to the force generated by the spring 17. Since the force generated by the spring 17 is directed downwards by 30 ° with respect to a horizontal, the effective area of the piston 16 is also directed downward by 30 ° relative to a horizontal.
  • the area of the rearwardly facing surface of the block 15, on which the active surface of the piston 16 at least at a position of the baking 2 acts on the first region of the adjustment an effective range of the jaw 2, in which the force generated by the spring 17 for tension of the jaw 2 is physically transferred to its holding position on the jaws 2.
  • FIG. 3 shows an oblique view of a vertically oriented, running in the ski longitudinal section through the heel unit 1 in the release configuration in which the jaw 2 is in its release position.
  • the jaw 2 is moved along the adjustment from its holding position to its release position.
  • the jaw 2 is first moved upwards. This can be done, for example, by the heel area of a heel machine 1 held in the ski boot or by a movement of the obliquely back upwards facing free end of the opening lever 5 down.
  • the lower rod 10 is moved with the block 15 upwards, whereby the piston 16 is pressed against the bias of the spring 17 obliquely back up.
  • the jaw 2 Only when the jaw 2 is moved sufficiently far up, the jaw 2 can be tilted as already described with its upper portion to the rear by the upper bar 11 of the groove 14 is moved along back to the bottom. In this case, the lower rod 10 is moved together with the block 15 again slightly downwards. In this movement sequence, the jaw 2 is thus first moved upward along a vertically oriented first area of the adjustment path against the force generated by the spring 17. However, as soon as the upper rod 11 is moved upwardly beyond the notch 13, the jaw 2 is moved downwardly along a second portion of the adjustment path along the groove 14. In this case, the lower rod 10 is moved together with the block 15 again slightly downwards, so that the piston 16 is again moved slightly obliquely forward down and the tension of the spring 17 is slightly reduced.
  • the jaw 2 In order to adjust the heel unit 1 from the release configuration back into the holding configuration, the jaw 2 is first tilted forward with its upper portion. As soon as the upper rod 11 is above the notch 13, the jaw 2 is automatically lowered vertically downwards to its holding position due to the tension of the spring 17. In order to tilt the jaw 2 as required first to tilt forward, for example, the rearward facing free end of the opening lever 5 can be moved back up. But there is also the possibility that this is done with a downward force on the front end of the jaw 2. For example, with the heel of the ski boot arranged at the front lower end of the jaw 2 entry element 19 are pressed down. Also, thereby, the jaws 2 is tilted forward until it can be automatically lowered by the tension of the spring 17 vertically down to its holding position.
  • the heel area of the ski boot is already encompassed with the touchdown on the entry element 19 from the top of the jaw 2 and a little bit forward to the side, thereby also the Heel area of the ski boot lowered together with the jaw 2 to the ski out until the jaw 2 is in its holding position and the ski boot is locked in the lowered position.
  • the automatic heel unit 1 Due to the course of the adjustment, the automatic heel unit 1 enables a safety release in the forward direction: As already mentioned, the jaw 2 in its holding position can lock the heel area of a ski boot held in the ski binding in the lowered position. This allows the ski boot to be attached to the ski for a descent. Now, when the skier falls forward, an upward force acts on the heel area of the ski boot. If this force is greater than the force with which the jaw 2 is biased to its holding position, the heel portion of the ski boot will push the jaws 2 upwardly along the first portion of the adjustment path. The energy absorbed by the automatic heel unit 1 corresponds to the distance traveled upwards by the jaw 2 multiplied by the downward force acting on the jaws 2.
  • the entire energy of the fall is absorbed by the heel unit 1 and there is no safety release.
  • the energy of the stem is greater than this force multiplied by the length of the first range of travel, the jaw 2 is moved to the upper end of the first range of travel and tilted rearwardly along the second range of travel. As a result, the heel area of the ski boot is released by the automatic heel unit 1, so that it comes to a safety release.
  • the energy that can be absorbed in a fall from the heel unit, 1, until it comes to a safety release can be adjusted by the bias of the spring 17 by means of the threaded sleeve 18.
  • the force with which the jaw 2 is pressed down is only half as strong as the force generated by the spring 17, because the spring 17 is inclined at an angle of 60 ° to the vertical and the effective surface of the piston 16 perpendicular to Alignment of the spring 17 is aligned.
  • the inclination of the spring 17 and the piston 16 has the advantage that the force with which the jaw 2 is pressed down, can be increased because of the inclination the spring 17 and the piston 16, a larger and more than twice as strong spring 17 can be used as if the spring 17 would be vertically aligned and would press from above vertically against the block 15 and the lower rod 10.
  • the safety release enabled by the automatic heel unit 1 can be set more strongly so that the automatic heel unit 1 can absorb a greater amount of energy until a safety release occurs.
  • the inclination of the spring 17 and the piston 16 also has the advantages that the threaded sleeve 18 for setting the safety release optimally accessible is and that the area below the spring 17 of the jaw carrier 3 is available for other functions of the heel unit 1. As described below, this area below the spring 17 in the automatic heel unit 1 offers space for the mechanics of two further functions of the automatic heel unit 1.
  • the jaw carrier 3 When heel machine 1, which in the FIGS. 1 to 3 is shown, the jaw carrier 3 is slidably mounted in the longitudinal direction of the ski on the base member 4 and can be compared to the base member 4 as in the FIG. 4 be moved shown in a rear position. In this rear position, the heel unit 1 is in a climbing configuration, in which the heel area of the ski boot is released from the jaw 2, so that the ski boot with his heel area can be lifted off the ski and lowered back to the ski without the ski boot from the ski boot Baking 2 is locked.
  • the mechanism that allows the jaw carrier 3 to move relative to the base member 4 between the ascent configuration and the holding configuration is located below the spring 17.
  • the automatic heel unit 1 has such an ascent configuration, it is advantageously used in touring ski bindings of the aforementioned second or third type or in telemark or cross-country ski bindings, in which for descents a holding configuration is desired, in which the heel area of the ski boot is locked in a lowered position.
  • the invention is not limited to the automatic heel unit 1 described above.
  • the heel machine it is not necessary for the heel machine to include a base member as described above.
  • the jaw carrier is mounted directly on any existing base element.
  • the jaw carrier for example, as in the WO 96/23559 A1 (Fritschi AG Apparatebau) described be arranged on the sole support, which is pivotable in its front region about a horizontally oriented in the transverse direction axis. In this case, since the heel piece can be pivoted away from the ski together with the sole support in the ascent configuration of the toe binding, it is not necessary for the heel piece to have an ascent configuration itself.
  • an heel automat according to the invention can also be used for other ski bindings such as, for example, downhill bindings.
  • the heel box is not required to have an ascent configuration.
  • the jaw carrier is biased forward relative to the base member.
  • the heel machine can also be designed to be easily displaceable relative to the base element in order to be able to adapt a distance between the front automatic machine and the heel counter to a size of a ski boot to be held.
  • the jaw carrier is fixedly mounted on the base member, wherein the jaw carrier and the base member may also be integrally formed as an element.
  • the invention may otherwise be carried out deviating from the heel machine 1 described above.
  • another elastic element than the spring 17 can be used.
  • the spring is oriented at a different angle than at an angle of 60 ° to the orientation of the first portion of the adjustment.
  • the first region of the adjustment path can be oriented differently than vertically.
  • the first region of the adjustment can also be curved.
  • the adjustment path has no second area. In this case, the first range of the adjustment can also extend over the entire adjustment path.
  • the effective area of the piston may be oriented or curved differently than described above.
  • the block 15 and the effective range of the baking can be shaped differently.
  • a pawl is arranged, which is pivotally mounted on the jaw carrier and transmits the force generated by the elastic element from the piston to the jaws.
  • the automatic heel unit does not comprise a piston, but that the elastic element acts directly on the effective range of the jaw or on the possibly present pawl.
  • the storage of the baking on the back support can be performed differently.
  • the jaw may be supported on the jaw.
