Description

Die Erfindung betrifft einen Fersenhalter für Sicherheitsskibindungen mit einer auf einer skifesten Führungsschiene gegen die Kraft zumindest einer Schubfeder verschiebbar geführten, einen Lagerbock tragenden Grundplatte, an welchem Lagerbock ein Sohlenhalter schwenkbar angeordnet ist, der mittels einer an der einen Seite an einer Steuerfläche abgestützten, an der anderen Seite von einer Feder, die in einem schwenkbar gelagerten Federgehäuse angeordnet ist, beaufschlagten Sperrklinke in der Abfahrtsstellung gehalten ist.The invention relates to a heel holder for safety ski bindings with a base plate which is displaceably guided on a ski-fixed guide rail against the force of at least one thrust spring and which supports a bearing block, on which bearing block a sole holder is pivotably arranged, which is supported on one side on a control surface on which on the other side, a pawl which is acted upon by a spring which is arranged in a pivotably mounted spring housing is held in the downward position.

Ein Fersenhalter der eingangs genannten Art ist beispielsweise in dem technischen Handbuch TECH60 des Tyrolia-Freizeitgeräte Gesmb H & CO, Seite 28 ; erschienen 1979 beschrieben. Dieser Fersenhalter hat sich in der Praxis gut bewährt und ist für den Benützer komfortabel zu handhaben, weist jedoch den Nachteil auf, daß bei einer Auslösung des Vorderbackens, beispielsweise bei einem Drehsturz, der Sohlenhalter geschlossen bleibt, so daß der Skifahrer zum erneuten Anlegen der Bindung diesen mittels eines Auslösehebels von Hand aus öffnen muß.A heel holder of the type mentioned at the outset is, for example, in the technical manual TECH60 from Tyrolia-Freizeitgeräte Gesmb H & CO, page 28; appeared in 1979. This heel holder has proven itself in practice and is comfortable to use for the user, but has the disadvantage that when the toe is released, for example in the event of a lintel fall, the sole holder remains closed, so that the skier can put on the binding again this must be opened by hand using a release lever.

Die Erfindung hat sich daher die Aufgabe gestellt, einen Fersenhalter der eingangs gennanten Art weiterzuentwickeln, so daß er auch nach einer Auslösung des Vorderbackens einsteigbereit ist.The invention is therefore based on the object of further developing a heel holder of the type mentioned at the outset, so that it is ready for entry even after the toe piece has been triggered.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, daß am skifesten Widerlager der Schubfeder(n) zumindest ein Steuerteil befestigt oder angelenkt ist, welcher eine Ausparung der Grundplatte durchsetzt und weicher bei Entlasten der Schubfeder(n) ohre Fersenauslösung des Federgehäuse von seiner Abstützfläche an der Sperrklinke wegdrückend beaufschlagt.The object is achieved according to the invention in that at least one control part is attached or articulated to the ski-fixed abutment of the thrust spring (s), which passes through a recess in the base plate and softer when the thrust spring (s) is released without heel release of the spring housing from its support surface on the pawl pushing away.

Durch die erfindungsgemäßen Maßnahmen wird das gesetzte Ziel einwandfrei erreicht. Bei einer reinen Vorderbackenauslösung wird der Fersenhalter durch Entlastung der Schubfeder(n) in Richtung zur Skipitze hin verschoben, während der Steuerteil wirkfest verbleibt. Infolge dieser Relativbewegung zwischen dem Steuerteil und dem Fersenhalter mit seinem Federgehäuse wird letzteres von seiner Abstützfläche an der Sperrklinke weggedrückt. Die Sperrklinke kommt somit von der Steuerfläche des Lagerbockes frei, so daß der Sohlenhalter in die Offenstellung verschwenken kann ; der Fersenhalter ist einsteigbereit.With the measures according to the invention, the goal set is achieved perfectly. In the case of a pure toe release, the heel holder is moved towards the ski tip by relieving the thrust spring (s), while the control part remains effective. As a result of this relative movement between the control part and the heel holder with its spring housing, the latter is pressed away from its support surface on the pawl. The pawl is thus free from the control surface of the bearing block, so that the sole holder can pivot into the open position; the heel holder is ready to step on.

Auch ist es erfindungsgemäß von Vorteil, wenn der Steuerteil am skifesten Widerlager im Bereich eines spitzen Winkels von der Skiebene weg hochschwenkbar ist und von einer Rückholfeder, welche vorzugsweise eine Schenkelfeder ist, in seiner Ruhelage gehalten ist. Auf diese Weise wird die zwischen dem Federgehäuse und dem Steuerteil auftretende Reibung wirkungsvoll vermindert.It is also advantageous according to the invention if the control part on the ski-fixed abutment can be swung up in the region of an acute angle away from the ski plane and is held in its rest position by a return spring, which is preferably a leg spring. In this way, the friction occurring between the spring housing and the control part is effectively reduced.

Ein weiteres Merkmal der Erfindung besteht darin, daß jeder Steuerteil eine Steuernase aufweist, welche bei geschlossenem Fersenhalter, sowohl in entspannter als auch in vorgespannter Lage der Schubfeder(n) in je einer Rastvertiefung des Federgehäuses zum Liegen kommt, welche Rastvertiefungen in Skilängsrichtung hintereinander angeordnet sind und zwischen welchen Rastvertiefungen eine in Richtung zur Skioberseite weisende Steuernocke vorgesehen ist. Die eine Rastvertiefung gewährleistet ein ungehindertes Schließen des Fersenhalters auch ohne eingesetzten Skischuh, die zweite dient zur Aufnahme des Steuerteiles bei in die Bindung eingesetztem Skischuh. Die zwischen diesen Rastvertiefungen angeordnete Steuernocke wird bei einer reinen Auslösung des Vorderbacknes von der Steuernase des Steuerteiles beaufschlagt, wodurch das Federgehäuse angehoben wird und von seiner Abstützfläche an der Sperrklinke freikommt.Another feature of the invention is that each control part has a control lug, which comes to rest when the heel holder is closed, both in the relaxed and in the pretensioned position of the thrust spring (s) in one detent depression of the spring housing, which detent depressions are arranged one behind the other in the longitudinal direction of the ski and between which locking recesses a control cam pointing in the direction of the top of the ski is provided. One locking recess ensures an unimpeded closing of the heel holder even without a ski boot inserted, the second serves to hold the control part when the ski boot is inserted into the binding. The control cam arranged between these locking recesses is acted upon by the control lug of the control part when the front jaw is triggered only, whereby the spring housing is raised and is released from its support surface on the pawl.

Eine besonders vorteilhafte Ausgestaltung der Erfindung ist dann gegeben, wenn das skifeste Widerlager, wie an sich bekannt, von einer Gabel gebildet ist, die in an sich bekannter Weise einerends einen Steg zur Abstützung der Schubfeder(n) aufweist und anderends mit einer zum Ver- bzw. Entrasten mit der Führungsschiene vorgesehenen Raste versehen ist, und daß der bzw. die Steuerteil(e) an den Schenkeln der Gabel befestigt bzw. angelenkt ist bzw. sind. Auf diese Weise ist eine Anordung des Steuerteiles an vielen bekannten auch am Markt befindlichen Fersenhaltern mit geringstem baulichen Aufwand gewährleistet.A particularly advantageous embodiment of the invention is given when the ski-fixed abutment, as is known per se, is formed by a fork which, in a manner known per se, has a web on one end for supporting the thrust spring (s) and on the other hand with a or unlocking is provided with the guide rail provided, and that the control part (s) is or are attached to the legs of the fork. In this way, an arrangement of the control part on many known heel holders, which are also on the market, is ensured with the least constructional effort.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung werden nun anhand der Zeichnung, die zwei Ausführungsbeispiele darstellt, näher beschrieben. Es zeigen : die Fig. 1 bis 4 ein erstes Ausführungsbeispiel eines erfindungsgemäßen Fersenhalters, Fig. 1 den erfindungsgemäßen Fersenhalter in Seitenansicht im Schnitt in geschlossener Lage ohne eingesetzten Skischuh, Fig. 2 den Rastmechanismus des Fersenhalters in vergrößertem Maßstab ebenfalls in Seitenansicht im Schnitt in einer Lage ohne eingesetzten Skischuh, die Fig. 3 den Rastmechanismus ähnlich zu Fig. 2 jedoch in seiner Lage mit eingesetztem Skischuh, Fig. 4 eine Lage des Rastmechanismus während einer Sicherheitsauslösung des (nicht dargestellten) Vorderbackens und Fig. 5 ein zweites Ausführungsbeispiel in einer ähnlichen Darstellung wie Fig. 2.Further features, advantages and details of the invention will now be described with reference to the drawing, which shows two exemplary embodiments. 1 to 4 show a first exemplary embodiment of a heel holder according to the invention, FIG. 1 shows the heel holder according to the invention in a side view in section in the closed position without a ski boot inserted, FIG. 2 shows the locking mechanism of the heel holder in an enlarged scale also in a side view in section in one Position without inserted ski boot, FIG. 3 shows the locking mechanism similar to FIG. 2 but in its position with inserted ski boot, FIG. 4 shows a position of the locking mechanism during a safety release of the toe (not shown) and FIG. 5 shows a second embodiment in a similar way Representation as in FIG. 2.

Wie aus Fig. 1 ersichtlich ist, ist auf der Oberseite eines Skis 1 eine Führungsschiene 2 mittels (nicht dargestellter) Schrauben befestigt. Auf der Führungsschiene 2 ist eine Grundplatte 3 des Fersenhalters in der Längsrichtung des Skis 1 verschiebbar geführt und in an sich bekannter Weise zur Anpassung der Bindung an unterschiedlich lange Skischuhe in der jeweils gewünschten Lage verrastbar. In einer Aussparung 3a der Grundplatte 3 ist eine Schubfeder 5 angeordnet, deren eines Ende an einem Stützteil 3b der Grundplatte 3 und deren anderes Ende an einem Quersteg einer als skifestes Widerlager 6 dienenden Gabel abgestützt ist, die mittels zweier Anzeigezapfen 6a den Rand der Ausparung 3a übergreift. Der Fersenhalter ist somit gegen die Kraft der Schubfeder 5 auf der Führungsschiene 2 verschiebbar geführt. Die Anzeigezapfen 6a dienen im Zusammenhang mit einer an der Grundplatte 3 befindlichen Skala bei in die Bindung eingesetztem Skischuh zum Ablesen des Anpreßdruckes der Fersenhalters gegen den (nicht dargestellten) Vorderbacken. Das Widerlager 6 weist zwei seitlich der Schubfeder 5 und parallel zur Längsachse des Skis 1 verlaufende Schenkel 6b auf, die in dem dem Quersteg des Widerlagers 6 abgewandten Ende der Aussparung 3a der Grundplatte 3 zu einer Rastzunge zusammenlaufend gestaltet sind, welche in bekannter und daher nicht dargestellter Weise zum Verrasten der Fersenhalters an der Führungsschiene 2 vorgesehen ist. Zumindest einer der beiden Schenkel 6b des Widerlagers 6 trägt einen Steuerteil 10, der die Aussparung 3a der Grundplatte 3 von unten her durchsetzt und auf dessen Gestalt und Wirkungsweise noch eingegangen wird.As can be seen from FIG. 1, a guide rail 2 is fastened to the top of a ski 1 by means of screws (not shown). On the guide rail 2, a base plate 3 of the heel holder is displaceably guided in the longitudinal direction of the ski 1 and, in a manner known per se, can be locked in the desired position in order to adapt the binding to ski boots of different lengths. A thrust spring 5 is arranged in a recess 3a of the base plate 3, one end of which is connected to a support part 3b the base plate 3 and the other end thereof is supported on a crossbar of a fork serving as a ski abutment 6, which overlaps the edge of the recess 3a by means of two indicator pins 6a. The heel holder is thus guided against the force of the thrust spring 5 on the guide rail 2. The indicator pins 6a are used in connection with a scale located on the base plate 3 when the ski boot is inserted into the binding for reading the contact pressure of the heel holder against the toe (not shown). The abutment 6 has two legs 6b extending to the side of the thrust spring 5 and parallel to the longitudinal axis of the ski 1, which are designed in the end of the cutout 3a of the base plate 3 facing away from the transverse web of the abutment 6 to form a locking tongue, which are known and therefore not shown way is provided for locking the heel holder on the guide rail 2. At least one of the two legs 6b of the abutment 6 carries a control part 10, which passes through the cutout 3a of the base plate 3 from below and the shape and mode of operation of which will still be discussed.

Auf der Grundplatte 3 ist ein Lagerbock 7 befestigt, an dem ein Sohlenhalter 8 um eine Achse 9 schwenkbar gelagert ist. Der Sohlenhalter 8 trägt auf einer weiteren, parallel zur erstgennanten verlaufenden Achse 11 eine ebenfalls verschwenkbare Sperrklinke 12, welche in der Abfahrtsstellung des Fersenhalters mittels einer Rastnase 12a eine Raste 17a einer am Lagerbock 7 ausgebildeten Steuerfläche 17 untergreift. Weiters ist auf der Schwenkachse 9 des Sohlenhalters 8 ein, in Draufsicht betrachtet, etwa U-förmiges Federgehäuse 13 gelagert, welcher in seinen beiden Seitenwangen Längsschlitze 13a aufweist, die eine Führung für einen Sperrteil 14 bilden. Der Sperrteil 14 ist von dem einen Ende einer Auslösefeder 15 beaufschlagt, deren anderes Ende an einem Federwiderlager 16 abgestützt ist, das mittels einer drehbar im Federgehäuse 13 gelagerten Schraube 28 in der Achsrichtung der Auslösefeder 15 verstellbar ist. Die Sperrklinke 12 bildet für den Sperrteil 14 eine Raste 12b, in welche dieser durch die Auslösefeder 15 gedrückt wird. Im Anschluß an die Raste 12b ist an der Sperrklinke 12 eine Ausnehmung 12c vorgesehen, .die als Freistellung dient, und in welche bei Betätigen eines Auslösehebels 18 der Sperrteil 14 einrastet.On the base plate 3, a bearing block 7 is attached, on which a sole holder 8 is pivotally mounted about an axis 9. The sole holder 8 carries on a further, parallel to the first-mentioned axis 11 also a pivotable pawl 12, which engages under the catch 17a of a control surface 17 formed on the bearing block 7 in the down position of the heel holder by means of a detent 12a. Furthermore, viewed in plan view, an approximately U-shaped spring housing 13 is mounted on the pivot axis 9 of the sole holder 8 and has longitudinal slots 13 a in its two side cheeks, which form a guide for a locking part 14. The locking part 14 is acted upon by one end of a release spring 15, the other end of which is supported on a spring abutment 16 which is adjustable in the axial direction of the release spring 15 by means of a screw 28 rotatably mounted in the spring housing 13. The pawl 12 forms a catch 12b for the locking part 14, into which it is pressed by the release spring 15. Following the detent 12b, a recess 12c is provided on the pawl 12, which serves as an exemption and into which the locking part 14 engages when a release lever 18 is actuated.

Der Auslösehebel 18 übergreift seitlich den Sohlenhalter 8 und ist an der am Sohlenhalter 8 angeordneten Achse 11 schwenkbar gelagert, an welcher Achse 11 auch die Sperrklinke 12 angelenkt ist. Ein Bolzen 19 ist parallel zur Achse 11 verlaufend am Auslösehebel 18 befestigt, durchsetzt sowohl den Sohlenhalter 8 als auch die Seitenwände des Federgehäuses 13 und ist in diesen beiden Bauteilen jeweils in Langlöchern 8b, 13b gleitbeweglich geführt. Hiebei sind die beiden am Sohlenhalter 8 vorgesehenen Langlöcher 8b konzentrisch zur Schwenkachse 11 angeordnet, die beiden am Federgehäuse 13 ausgebildeten Langlöcher 13b sind etwa im rechten Winkel zur Längsertreckung der Langlöcher 8b des Sohlenhalters 8 angeordnet. Bei einem Hochschwenken des Auslösehebels 18 gleitet der Bolzen 19 in den Langlöchern 8b des Sohlenhalters 8 nach oben und verschwenkt unter gleichzeitigem Gleiten in den Langlöchern 13b des Federgehäuses 13 in Richtung zur Skispitze, dieses um die Achse 9 ebenfalls nach oben. Dadurch kommt der Sperrteil 14 außer Eingriff von der Raste 12b der Sperrklinke 12, wodurch die Sperrklinke 12 frei verschwenken kann und ihre Rastnase 12a von der Raste 17a der Steuerfläche 17 des Lagerbockes 7 freikommt, der Sohlenhalter 8 verschwenkt, unterstützt von einer an der Achse 9 angeordneten Öffnungsfeder 20, in die Offenstellung.The release lever 18 laterally overlaps the sole holder 8 and is pivotally mounted on the axis 11 arranged on the sole holder 8, on which axis 11 the pawl 12 is also articulated. A bolt 19 is mounted parallel to the axis 11 on the release lever 18, passes through both the sole holder 8 and the side walls of the spring housing 13 and is slidably guided in each of these two components in elongated holes 8b, 13b. The two elongated holes 8b provided on the sole holder 8 are arranged concentrically to the pivot axis 11, the two elongated holes 13b formed on the spring housing 13 are arranged approximately at right angles to the longitudinal extension of the elongated holes 8b of the sole holder 8. When the release lever 18 is pivoted upward, the bolt 19 slides upward in the elongated holes 8b of the sole holder 8 and pivots while simultaneously sliding in the elongated holes 13b of the spring housing 13 in the direction of the ski tip, this also around the axis 9 upwards. As a result, the locking part 14 disengages from the catch 12b of the pawl 12, whereby the pawl 12 can pivot freely and its catch 12a is released from the catch 17a of the control surface 17 of the bearing block 7, the sole holder 8 swivels, supported by one on the axis 9 arranged opening spring 20, in the open position.

Der am Schenkel 6b des Widerlagers 6 befestigte Steuerteil 10 weist eine Steuernase 10a auf, die in der geschlossenen Lage des Sohlenhalters 8 und bei nicht eingesetztem Skischuh in einer Rastvertiefung 13c der zugehörigen Seitenwand des Federgehäuses 13 zum Liegen kommt. Diese Rastvertiefung 13c ist an der unteren Kante dieser Seitenwand ausgebildet (siehe Fig. 2). Während des Einsteigens in den Fersenhalter mittels eines Skischuhes verschiebt dieser den Fersenhalter gegen die Kraft der Schubfeder 5 auf der skifesten Führungsschiene 2 in Richtung zum Skiende, wobei nach erfolgtem Niederschwenden des Sohlenhalters 8 der dem Ski 1 gegenüber ortsfest verbleibende Steuerteil 10 mit seiner Steuernase 10a in einer weiteren, ebenfalls an der unteren Kante der Seitenwand des Federgehäuses 13 ausgebildeten Rastvertiefung 13d zum Liegen kommt.The control part 10 fastened to the leg 6b of the abutment 6 has a control lug 10a which comes to rest in the closed position of the sole holder 8 and when the ski boot is not inserted in a recess 13c in the associated side wall of the spring housing 13. This locking recess 13c is formed on the lower edge of this side wall (see FIG. 2). While getting into the heel holder by means of a ski boot, the latter moves the heel holder against the force of the thrust spring 5 on the ski-fixed guide rail 2 in the direction of the end of the ski, after the sole holder 8 has been turned down, the control part 10 which remains stationary with respect to the ski 1 with its control nose 10a in a further, also on the lower edge of the side wall of the spring housing 13 formed recess 13d comes to rest.

Erfolgt nun bei einem Sturz des Skifahrers, beispielsweise bei einem Drehsturz, ein Auslösen des (nicht dargestellten) Vorderbackens, so wird der Fersenhalter durch die sich entspannende Schubfeder 5 auf der Führungsschiene 3 in Richtung zum Vorderbacken verschoben. Hiebei beaufschlagt die Steuernase 10a des Steuerstückes 10 eine zwischen den beiden Rastvertiefungen 13c, 13d ausgebildete Steuernocke 13e des Federgehäuses 13 und drückt das Federgehäuse 13 nach oben u. zw. um jenes Ausmaß, das erforderlich ist, um den im Federgehäuse 13 gelagerten Sperrteil 14 aus der Raste 12b der Sperrklinke 12 zu heben (siehe Fig. 4). Die Sperrklinke 12 ist nun nicht mehr von der Auslösefeder 15 beaufschlagt. Der Öffnungsvorgang des Sohlenhalters 8 erfolgt von der Öffnungsfeder 20 unterstützt in der schon beschriebenen, auch beim willkürlichen Öffnen stattfindenden Weise. Der Fersenhalter ist einsteigbereit, das erneute Einsteigen in die Bindung erfolgt auf an sich bekannte Weise entweder durch Schließen des Auslösehebels 18 und anschließendes Niederschwenken des Sohlenhalters 8 mit dem Skischuh oder dadurch, daß zuerst der Sohlenhalter 8 und anschließend der Auslösehebel 18 verschwenkt wird.If the toe piece (not shown) is triggered when the skier falls, for example in the event of a turning fall, the heel holder is displaced in the direction of the toe piece by the relaxing thrust spring 5 on the guide rail 3. Hiebei acts on the control lug 10a of the control piece 10 between the two locking recesses 13c, 13d formed control cam 13e of the spring housing 13 and presses the spring housing 13 upwards and. between the extent that is required to lift the locking part 14, which is mounted in the spring housing 13, out of the catch 12b of the pawl 12 (see FIG. 4). The pawl 12 is no longer acted upon by the release spring 15. The opening process of the sole holder 8 is supported by the opening spring 20 in the manner already described, which also takes place during the arbitrary opening. The heel holder is ready for boarding, the re-entry into the binding is carried out in a manner known per se either by closing the release lever 18 and then swiveling the sole holder 8 down with the ski boot, or by first pivoting the sole holder 8 and then the release lever 18.

Eine Abwandlung der Ausgestaltung des Steuerteils 10 nach den Fig. 1 bis 4 zeigt der Steuerteil 10' nach Fig. 5. Dabei ist der Steuerteil 10' an einer am Schenkel 6b des Widerlagers 6 gelagerten Achse 10'b von der Skiebene weg in einem durch einen nicht dargestellten Anschlag begrenzten Bereich schwenkbar angelenkt und von einer Schenkelfeder 21 in seiner in dieser Figur dargestellten Lage gehalten. In der Abfahrsstellung des Fersenhalters greift, wie die Fig. 5 zeigt, der Steuerteil 10' mit seiner Steuernase 10'a in die hintere Rastvertiefung 13c des Federgehäuses 13 ein. Diese Lage entspricht jener der Fig. 2 des ersten Ausführungsbeispiels, in welcher der Fersenhalter ohne eingesetzten Skischuh dargestellt ist. Diese Ausgestaltung ist bezüglich Reibung günstiger als die des ersten Ausführungsbeispiels, weil durch die schwenkbare Lagerung des Steuerteils 10' die zwischen dem Federgehäuse 13 und dem Steuerteil 10' auftretende Reibung vermindert wird (Rollreibung anstatt Gleitreibung).The control part shows a modification of the design of the control part 10 according to FIGS. 1 to 4 10 'according to FIG. 5. The control part 10' is pivotably articulated on an axis 10'b mounted on the leg 6b of the abutment 6 away from the ski plane in a region limited by a stop, not shown, and by a leg spring 21 in it Figure shown location held. In the downward position of the heel holder, as shown in FIG. 5, the control part 10 'engages with its control lug 10'a in the rear latching recess 13c of the spring housing 13. This position corresponds to that of FIG. 2 of the first exemplary embodiment, in which the heel holder is shown without a ski boot inserted. This embodiment is more favorable in terms of friction than that of the first exemplary embodiment, because the pivotable mounting of the control part 10 'reduces the friction occurring between the spring housing 13 and the control part 10' (rolling friction instead of sliding friction).

Die Funktion dieses Ausführungsbeispiels entspricht im wesentlichen der des ersten Ausführungsbeispiels nach den Fig. 1-4 mit dem Unterschied, daß das nach oben Drücken des Federgehäuses 13 durch den gegen die Kraft der Aufstellfeder 21 in Gegenuhrzeigersinn verschwenkten Steuerteil 10' erfolgt.The function of this embodiment corresponds essentially to that of the first embodiment according to FIGS. 1-4 with the difference that the spring housing 13 is pressed upward by the control part 10 'pivoted counterclockwise against the force of the setting spring 21.

Die Erfindung ist auf die dargestellten Ausführungsbeispiele nicht eingeschränkt. So kann eine Vielzahl von Fersenbindungen, deren Kraftpaket eine Steuerfläche beaufschlagt und von dieser weg drückbar ist, mit geringem Aufwand mit dem erfindungsgemäßen Steuerteil versehen werden. Auch ist es selbstverständlich, zwei anstelle von einer einzigen Schubfeder vorzusehen.The invention is not restricted to the exemplary embodiments shown. A large number of heel bindings, the power pack of which acts on a control surface and can be pressed away from it, can be provided with the control part according to the invention with little effort. It is also a matter of course to provide two shear springs instead of one.
