Abstract

The safety ski binding has a toe iron, arranged before a front sole plate (21), and a heel iron which exerts a forwardly directed thrusting force onto the toe iron via the inserted ski boot. The toe iron has a sole holder (16) which supports the front part of the sole (14) of the ski boot (15) at the front, the side and the top and can be swivelled counter to a spring force directed essentially towards the front in each case about one of two essentially vertically axes (17) of rotation provided on both sides of the vertical longitudinal centre plane (11). Provided on the sole holder (16) at the region situated between the axes (17) of rotation is a stop (18) which faces downwards and towards the front and interacts with a sloping surface (19), which extends from the top to the bottom and the rear and is fixed to the housing, in such a way that, when the ski boot (15) is inserted, its sole (14) holds the sole holder (16) counter to the resilient prestress directed downwards at a height, at which the stop (18) is situated at least at a slight distance from the sloping surface (19). The ski boot (15) is mounted on the ski (22) so as to be resilient downwards, by which means, in the case of a forward fall, a counter-force to the sole holder restoring force is produced which is dependent on the slope of the sloping surface (19) and the resilient prestress of the sole holder (16) towards the bottom. <IMAGE>

Description

Die Erfindung betrifft einen vor einer vorderen Standplatte eines Skis angeordneten Vorderbacken einer Sicherheitsskibindung nach dem Obergegriff des Patentanspruchs 1 (wie zum Beispiel in FR-A-2 553 672 beschrieben).The invention relates to a front jaw of a safety ski binding arranged in front of a front base plate of a ski according to the preamble of claim 1 (as described for example in FR-A-2 553 672).

Bei einem seitenauslösbaren Vorderbacken einer Sicherheitsskibindung nach einem älteren Vorschlag (DE-A-37 20 440, Offenlegungstag 5.1.89) wird der höhenverschiebliche Sohlenhalter von unten durch einen doppelarmigen Hebel beaufschlagt, auf den über ein Stangen- und Keilgetriebe von der durch die Skistiefelsohle nach unten gedrückten Standplatte eine nach oben gerichtete Kraft auf den Sohlenhalter ausgeübt wird, um im Falle eines Vorwärtssturzes des Skifahrers die für die seitliche Auslösung des Vorderbackens erforderliche Seitenkraft herabzusetzen. Nachteilig an diesen bekannten Vorderbacken ist, daß zwischen der vertikal beweglich angeordneten Standplatte für den vorderen Teil der Sohle des Skistiefels und dem höhenverschieblichen Sohlenhalter ein Bewegungs- und Kraftübertragungsgetriebe angeordnet sein muß.In the case of a side-releasable toe piece of a safety ski binding according to an older proposal (DE-A-37 20 440, publication date 5.1.89), the height-adjustable sole holder is acted on from below by a double-armed lever, to which a rod and wedge transmission then moves from through the sole of the ski boot pressed down base plate an upward force is exerted on the sole holder in order to reduce the lateral force required for the lateral triggering of the toe piece in the event of a forward fall of the skier. A disadvantage of these known front jaws is that a movement and power transmission gear must be arranged between the vertically movable base plate for the front part of the sole of the ski boot and the height-adjustable sole holder.

Das Ziel der vorliegenden Erfindung besteht darin, einen Vorderbacken der eingangs genannten Gattung zu schaffen, bei dem im Falle einer Vorwärtsneigung und insbesondere Frontalsturzes des Skifahrers die Seitenauslösekraft in definierter Weise herabgesetzt wird, ohne daß zwischen der Standplatte und dem Sohlenhalter ein Kraftübertragungsgetriebe angeordnet sein muß.The aim of the present invention is to provide a front jaw of the type mentioned in which, in the event of a forward inclination and in particular a frontal fall of the skier, the lateral release force is reduced in a defined manner without a power transmission having to be arranged between the base plate and the sole holder.

Zur Lösung dieses Aufgabe sind die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 vorgesehen. Eine besonders bevorzugte Weiterbildung ist durch den Patentanspruch 2 gekennzeichnet.To achieve this object, the features of the characterizing part of claim 1 are provided. A particularly preferred further development is through claim 2 featured.

Der Erfindungsgedanke ist demnach darin zu sehen, daß der mit dem Sohlenhalter in Eingriff befindlichen Sohlenspitze bei einer Vorwärtsneigung, insbesondere einem Frontalsturz des Skifahrers eine definierte Bewegung nach unten ermöglicht wird, bis eine auf den Sohlenhalter nach unten wirkende und durch eine Feder oder die Schuhsohle selbst erzeugte Kraft den Anschlag gegen die Schrägfläche drückt, wodurch eine entlastende Kraft auf den Sohlenhalter in dem Sinne ausgeübt wird, daß die Seitenauslösung mit einer geringeren Kraft bewerkstelligt werden kann. Je stärker die Bewegung der Sohlenspitze nach unten ist, d.h. ein je intensiverer Druck auf den vorderen Teil der Schuhsohle von oben nach unten ausgeübt wird, umso länger bzw. umso weiter kann sich der Anschlag auf der Schrägfläche verschieben, d.h. während eines umso größeren Schwenkwinkels des Sohlenhalters bei der Seitenauslösung bleibt die Erniedrigung der Seitenauslösekraft aufrecht erhalten. Erfindugsgemäß hat also die ab einer bestimmten Abwärtsbewegung der Sohle wirksam werdende Gegenkraft zur Sohlenhalterrückstellkraft einen konstanten Wert. Je stärker die Sohlenspitze nach unten gedrückt wird, umso länger bleibt diese Gegenkraft bei der Seitenauslösung aufrechterhalten.The idea of the invention is therefore to be seen in the fact that the sole tip engaged with the sole holder allows a defined downward movement in the event of a forward inclination, in particular a frontal fall of the skier, until one acting down on the sole holder and by a spring or the shoe sole itself generated force presses the stop against the inclined surface, whereby a relieving force is exerted on the sole holder in the sense that the side release can be accomplished with a lower force. The stronger the movement of the sole tip is down, i.e. the more intense pressure is exerted on the front part of the shoe sole from top to bottom, the longer or the further the stop on the inclined surface can shift, i.e. during an even greater pivoting angle of the sole holder during the side release, the lowering of the side release force is maintained. According to the invention, the counterforce to the sole holder restoring force which takes effect from a certain downward movement of the sole has a constant value. The harder the tip of the sole is pressed down, the longer this counterforce remains when the side is released.

Auf besonders bevorzugte Weise wird die Abwärtsbewegung der Skistiefelsohle bei einem Vorwärtssturz durch die Maßnahmen des Anspruchs 3 gewährleistet.In a particularly preferred manner, the downward movement of the ski boot sole is ensured in the event of a forward fall by the measures of claim 3.

Nach einer bevorzugten Ausführungsform ist die Schrägfläche eben und erstreckt sich quer zur Skilängsrichtung.According to a preferred embodiment, the inclined surface is flat and extends transversely to the longitudinal direction of the ski.

Der Winkel der Schrägfläche darf nicht so steil werden, daß der Vorsprung ohne eine seitliche Auslösebewegung auf der Schrägfläche abwärts rutscht. Bevorzugte Winkel sind durch Anspruch 5 definiert. Der Winkel ist abhängig von der zur Verfügung stehenden, nach unten auf den Sohlenhalter ausgeübten Kraft zu wählen.The angle of the inclined surface must not become so steep that the projection slides down on the inclined surface without a lateral release movement. Preferred angles are through Claim 5 defined. The angle is dependent on the available force exerted downwards on the sole holder.

Das Ausführungsbeispiel nach Anspruch 6 hat den Vorteil, daß bei einer Seitenauslösebewegung lediglich die eine Hälfte des Sohlenhalters beansprucht, die andere dagegen kraftlos wird. Durch das Ausführungsbeispiel nach Anspruch 7 wird verhindert daß die vom Fersenbacken über den Skistiefel auf den Vorderbacken wirkende Anschubkraft ein seitliches Auslösemoment auf den Sohlenhalter ausübt. Durch geringfügige Versetzung der Abstützstellen in seitlicher Richtung relativ zu den Kippachsen können allerdings definierte geringfügige Spreiz- bzw. Schließkräfte ausgeübt werden.The embodiment according to claim 6 has the advantage that with a side release movement only one half of the sole holder is claimed, the other, however, is without power. The embodiment according to claim 7 prevents the pushing force acting from the heel cheek over the ski boot on the front cheek exerting a lateral triggering moment on the sole holder. By slightly displacing the support points in the lateral direction relative to the tilt axes, however, defined slight spreading or closing forces can be exerted.

Vorteilhafte Anordnungen für die Erzeugung der nach vorn gerichteten Federkraft sind in den Ansprüchen 8 und 9 definiert.Advantageous arrangements for generating the forward spring force are defined in claims 8 and 9.

Die Vorspannung des Sohlenhalters nach unten parallel zu den Kippachsen kann durch die Maßnahmen der Ansprüche 10, 11 oder 12 verwirklicht werden.The prestressing of the sole holder downward parallel to the tilting axes can be achieved by the measures of claims 10, 11 or 12.

Bevorzugt ist die Anordnung der Schrägfläche nach Anspruch 13, weil auf diese Weise eine ohnehin unten und vorn am Sohlenhalter vorgesehene Kante als Anschlag zur Zusammenarbeit mit der gehäusefesten Schrägfläche verwendet werden kann.The arrangement of the inclined surface according to claim 13 is preferred, because in this way an edge which is provided at the bottom and front of the sole holder can be used as a stop for cooperation with the inclined surface fixed to the housing.

Eine entsprechende Schrägfläche mit Anschlag kann auch im oberen Bereich des erfindungsgemäßen Vorderbacken vorgesehen sein, wie das im Einzelnen im Anspruch 14 definiert ist. Die bauliche Ausbildung dieser zusätzlichen Schrägfläche und des zusätzlichen Anschlages können analog den Ansprüchen 4, 5 sein. Lediglich die für die Verschiebung des Sohlenhalters nach oben erforderliche Kraft wird nicht durch eine Feder, sondern durch die Stiefelsohlenspitze erzeugt. Auf diese Weise kann auch die bei einem Rückwärtssturz zwischen dem Sohlenhalter und der Sohlenspitze auftretende Reibungskraft weitgehend kompensiert werden.A corresponding inclined surface with a stop can also be provided in the upper region of the front jaw according to the invention, as defined in detail in claim 14. The construction of this additional inclined surface and the additional stop can be analogous to claims 4, 5. Only for the shift of the sole holder upward force is not generated by a spring, but by the tip of the boot sole. In this way, the frictional force occurring between the sole holder and the sole tip in the event of a backward fall can be largely compensated for.

Die Anschläge und Schrägflächen können auch im Sinne des Anspruchs 15 kinematisch vertauscht werden.The stops and inclined surfaces can also be exchanged kinematically within the meaning of claim 15.

Die Ausführungsform nach Anspruch 16 bringt den Vorteil mit sich, daß der Sohlenhalter auch durch die von hinten auf den Vorderbacken wirkende Anschubkraft mit einer nach unten gerichteten Kraftkomponente beaufschlagt wird, welche den Sohlenhalter gegen die Oberseite der Sohlenspitze drückt und zu der erfindungsgemäß auf den Sohlenhalter von oben wirkenden Vorspannkraft beiträgt.The embodiment according to claim 16 has the advantage that the sole holder is also acted upon by the pushing force acting from behind on the front jaws with a downward force component which presses the sole holder against the top of the sole tip and, according to the invention, on the sole holder from contributes pre-tensioning force.

Nach den Figuren 1 und 2 ist auf der Oberseite eines Ski 22 unter dem vorderen Bereich der Sohle 14 eines Skistiefels 15 eine sich quer über die Oberseite erstreckende längliche Standplatte 21 vorgesehen, die durch eine Federanordnung 31 in der Weise auf der Oberseite des Skis 22 befestigt ist, daß sie bei einer Vorwärtsneigung des Skifahrers aufgrund der stärkeren Druckausübung durch die Sohle 14 um ein von der von oben ausgeübten Druckkraft abhängiges Stück nach unten ausweichen kann.According to FIGS. 1 and 2, on the top of a ski 22 under the front region of the sole 14 of a ski boot 15 there is provided an elongated base plate 21 which extends across the top and is secured by a spring arrangement 31 on the top of the ski 22 is that if the skier leans forward due to the greater pressure exerted by the sole 14, it can move downward by a distance dependent on the pressure force exerted from above.

Vor der Standplatte 21 ist auf dem Ski 22 ein Vorderbacken 23 angeordnet, der einen aus zwei Hälften 16a, 16b bestehenden Sohlenhalter 16 und ein am Ski 22 befestigtes Gehäuse 20 umfaßt. Die beiden Hälften 16a, 16b des Sohlenhalters 16 sind zur vertikalen Mittelängsebene 11 des Vorderbackens 23 symmetrisch ausgebildet, und zwar mit Ausnahme der Anlenkösen 16a′, 16a˝ bzw. 16b′, 16b˝, die höhenversetzt sind, um an ein un denselben, weiter unten beschriebenen Bolzen 28 angelenkt werden zu können.A front jaw 23 is arranged in front of the base plate 21 on the ski 22 and comprises a sole holder 16 consisting of two halves 16a, 16b and a housing 20 fastened to the ski 22. The two halves 16a, 16b of the sole holder 16 are formed symmetrically to the vertical central longitudinal plane 11 of the front jaw 23, with the exception of the articulation eyelets 16a ', 16a ′ and 16b', 16b sind, which are offset in height, to one and the same, further bolts 28 described below can be hinged.

Wie sich aus den Figuren 1 und 1a ergibt, weisen die Sohlenhalter-Hälften 16a, 16b vorn konkave Kippflächen 13 auf, die relativ schmal ausgebildet sind und sich vertikal von oben nach unten erstrecken. In diese Kippflächen greifen im wesentlichen komplementär dazu ausgebildete gehäusefeste Abstützflächen 12 ein. Die Kippflächen 13 werden durch eine Auslösefeder 26, die sich mit ihrer hinteren Seite an einem gehäusefesten Widerlager 20′ abstützt und mit ihrem anderen Ende über eine Federvorspannungseinstellschraube 32 und eine Zugstange 27 auf einen vertikal verlaufenden Bolzen 28 ein wirkt, an dem die beiden Sohlenhalter-Hälften 16a und 16b mittels der Anlenkösen 16a′, 16b′ bzw. 16a˝ bzw. 16b˝ in der Mitte zwischen den beiden Abstützflächen 12 angelenkt sind, nach vorn gegen die Abstützflächen 12 gedrückt.As can be seen from FIGS. 1 and 1a, the sole holder halves 16a, 16b have concave tilting surfaces 13 at the front, which are relatively narrow and extend vertically from top to bottom. These support surfaces 12 are essentially complementary to the housing-fixed support surfaces 12. The tilting surfaces 13 are by a release spring 26, which is supported with its rear side on a housing-fixed abutment 20 'and with its other end via a spring preload adjusting screw 32 and a pull rod 27 on a vertically extending bolt 28 acts on which the two sole holder halves 16a and 16b are articulated by means of the articulation eyelets 16a ', 16b' or 16a˝ or 16b˝ in the middle between the two support surfaces 12, pressed forward against the support surfaces 12.

Wirkt jetzt beispielsweise eine seitliche Kraft F (Fig.1) auf die Sohle 14 des Skistiefels 15, beispielsweise aufgrund eines Drehsturzes des Skifahrers, so schwenkt die rechte Hälfte 16a des Sohlenhalter 16 nach rechts aus, und zwar um die vertikale Kippachse 17 (Fig. 1, 1a). Die linke Hälfte 16b des Sohlenhalter 16 wird dabei kraftlos.If, for example, a lateral force F (FIG. 1) now acts on the sole 14 of the ski boot 15, for example due to a skid of the skier, the right half 16a of the sole holder 16 swings out to the right, specifically about the vertical tilt axis 17 (FIG. 1, 1a). The left half 16b of the sole holder 16 becomes weak.

Eine Vorspannungsfeder 24 erstreckt sich vertikal beispielsweise zwischen dem hinteren Endbereich der Zugstange 27 und der Bodenplatte 10 und spannt den Sohlenhalter 16 in einer weiter unten erläuterten Weise nach unten vor.A bias spring 24 extends vertically, for example, between the rear end portion of the tie rod 27 and the base plate 10 and biases the sole holder 16 downward in a manner explained below.

Erfindungsgemäß befindet sich unterhalb des vorderen Endes des Sohlenhalters 16 in der Mitte zwischen den beiden Kippachsen 17 eine von oben nach unten und hinten schrägverlaufende ebene Schrägfläche 19, die mit einem durch die untere vordere Kante des Sohlenhalters 16 gebildeten Anschlag 18 zusammenwirkt.According to the invention, below the front end of the sole holder 16, in the middle between the two tilt axes 17, there is a flat inclined surface 19 which slopes obliquely from top to bottom and rear and which cooperates with a stop 18 formed by the lower front edge of the sole holder 16.

Die Anordnung der Schrägfläche 19 ist derart, daß bei eingestelltem Skistiefel 15 (Fig. 2) und normaler Haltung des Skifahrers ohne übermäßige Vorlage der Anschlag 18 keine Kraft von oben auf die Schrägfläche 19 ausübt und insbesondere einen geringen Abstand von der Schrägfläche 19 aufweist.The arrangement of the inclined surface 19 is such that when the ski boot 15 (FIG. 2) is set and the skier is in a normal posture without excessive presentation of the stop 18, no force is exerted on the inclined surface 19 from above and in particular is at a small distance from the inclined surface 19.

Gerät der Skifahrer nunmehr in Vorlage z.B. bei einem Frontalsturz, so erhöht sich die vom vorderen Teil der Sohle 14 auf die Standplatte 21 nach unten ausgeübt Kraft, so daß diese gegen die Kraft der Federanordnung 31 nach unten verschoben wird. Weiter kann die Schuhsohle bei der Abwärtsbewegung auch noch etwas um die Vorderkante 33 der Standplatte 21 nach unten kippen. Bei dieser Abwärtsbewegung des vorderen Teils der Sohle 14 bewegt sich auch die mit dem Sohlenhalter 16 in Eingriff stehende obere Fläche der Sohle 14 nach unten, so daß der Sohlenhalter 16 nunmehr unter der Einwirkung der Kraft einer ihn nach unten vorspannenden Vorspannungsfeder 24 entlang der Abstützflächen 12 relativ zum Gehäuse 20 nach unten rutschen kann, bis der Anschlag 18 an der Schrägflächen 19 zur Anlage kommt. Aufgrund geeigneter Stärke der Vorspannungsfeder 24 und Neigung der Schrägfläche 19 kann die Bewegung des Sohlenhalters 16 nach unten sich von jetzt ab nicht weiter fortsetzen, und zwar selbst dann nicht, wenn die obere Fläche der Sohle 14 noch nicht wieder in Eingriff mit der sie von oben beaufschlagenden unteren Fläche des Sohlenhalters 16 steht.If the skier now uses the template, for example in the event of a head-on fall, the force exerted on the base plate 21 from the front part of the sole 14 increases downward, so that the latter is displaced downward against the force of the spring arrangement 31. The sole of the shoe can also move downwards also tilt it down a bit around the front edge 33 of the base plate 21. During this downward movement of the front part of the sole 14, the upper surface of the sole 14, which engages with the sole holder 16, also moves downward, so that the sole holder 16 now under the action of the force of a prestressing spring 24 which prestresses it downward along the support surfaces 12 can slide down relative to the housing 20 until the stop 18 comes to bear on the inclined surfaces 19. Due to the appropriate strength of the bias spring 24 and inclination of the inclined surface 19, the movement of the sole holder 16 downwards cannot continue from now on, even if the upper surface of the sole 14 is not yet in engagement with it from above acts on the lower surface of the sole holder 16.

Aufgrund der Schräge der Schrägfläche 19 wird nunmehr durch die Vorspannung 24 eine nach hinten gerichtete Kraftkomponente auf die Mitte des Sohlenhalters 16 bzw. auf die untere Anlenköse 16b˝ der Sohlenhalter-Hälfte 16b ausgeübt, welche der von der Auslösefeder 26 nach vorn ausgeübten Kraft entgegengesetzt ist, also der Kraft der Auslösefeder 26 entgegenwirkt.Due to the incline of the inclined surface 19, a backward force component is now exerted on the center of the sole holder 16 or on the lower articulation eye 16b S of the sole holder half 16b by the bias 24, which is opposite to the force exerted by the release spring 26 to the front counteracts the force of the release spring 26.

Wird nun in einem solchen Falle die Schuhsohle 14 außerdem z.B. aufgrund eines kombinierten Frontal-Drehsturzes in seitlicher Richtung belastet, so ist die Kraft für die seitliche Ausschwenkung der betreffenden Hälfte 16a oder 16b des Sohlenhalters 16 entsprechend herabgesetzt. Die durch die zusätzliche Belastung erhöhte Reibung zwischen der Standplatte 21 und der Schuhsohle 14 kann so zumindest weitgehend durch eine Herabsetzung der Seitenauslösekraft kompensiert werden.In such a case, if the shoe sole 14 is also e.g. due to a combined frontal camber in the lateral direction, the force for the lateral pivoting of the relevant half 16a or 16b of the sole holder 16 is reduced accordingly. The increased friction between the base plate 21 and the shoe sole 14 due to the additional load can thus be at least largely compensated for by a reduction in the lateral release force.

Während der Seitenauslösebewegung des Sohlenhalters 16 rutscht der Anschlag 18 auf der Schrägfläche 19 so lange nach unten, bis der Sohlenhalter 16 wieder von oben mit der oberen Fläche der Stiefelsohle 14 in Eingriff kommt. Von diesem Moment an steht wieder die volle Seitenauslösekraft zur Verfügung, so daß der Kulminationspunkt der Seitenauslösebewegung jetzt schon überschritten sein sollte.During the side release movement of the sole holder 16, the stop 18 slides on the inclined surface 19 for so long down until the sole holder 16 again engages the upper surface of the boot sole 14 from above. From this moment on, the full page release force is available again, so that the culmination point of the page release movement should already be exceeded.

Die im wesentlichen konstante Gegenkraft zur Auslösekraft, die durch das Zusammenwirken des Anschlags 18 mit der Schrägfläche 19 erzeugt wird, ist also umso länger wirksam, je weiter sich die Sohlenspitze nach unten bewegt hat.The essentially constant counterforce to the triggering force, which is generated by the interaction of the stop 18 with the inclined surface 19, is therefore effective the longer the sole tip has moved downward.

Auch am oberen vorderen Ende des Sohlenhalters 16 kann in der Mitte zwischen den Kippachsen 17 ein Anschlag 18′ vorgesehen sein, der mit einer oberen gehäusefesten Schrägfläche 19′ in analoger Weise zusammenarbeitet.Also at the upper front end of the sole holder 16, a stop 18 'can be provided in the middle between the tilt axes 17', which cooperates with an upper housing-fixed inclined surface 19 'in an analogous manner.

Wenn der Skifahrer aus der Position nach Fig. 2 in Rücklage gerät, drückt die Spitze der Sohle 14 des Skistiefels 15 den Sohlenhalter gegen die Kraft der Vorspannungsfeder 24 nach oben, bis der Anschlag 18′ an der Schrägfläche 19′ zur Anlage kommt. Von diesem Augenblick an wird die seitliche Auslösekraft entsprechend herabgesetzt, wobei die Stärke der Herabsetzung von der Schräge der Schrägfläche 19′ und der von der Sohlenspitze auf den Sohlenhalter 16 nach oben ausgeübten Kraft abhängt.When the skier from the position of Fig. 2 is in reserve, the tip of the sole 14 of the ski boot 15 presses the sole holder against the force of the bias spring 24 upwards until the stop 18 'on the inclined surface 19' comes to rest. From this moment on the lateral release force is reduced accordingly, the strength of the reduction depends on the slope of the inclined surface 19 'and the force exerted by the sole tip on the sole holder 16 upwards.

Am Sohlenhalter 16 sind in Ausrichtung mit den Kippachsen 17 befindliche vordere Abstützrollen 29 und am hinteren Ende der schräg auswärts verlaufenden Sohlenhalter-Hälften 16a, 16b seitliche Abstützrollen 34 für den Rand der Sohle 14 vorgesehen. Die durch die vorderen Rollen 29 geschaffenen Abstützstellen 25 befinden sich in Ausrichtung mit den Kippachsen 17, damit durch die vom nicht dargestellten Fersenbacken herrührende Anschubkraft A keinen Einfluß auf das seitliche Auslösenverhalten des Vorderbacken 16 hat.Front support rollers 29, which are in alignment with the tilting axes 17, are provided on the sole holder 16 and lateral support rollers 34 for the edge of the sole 14 are provided at the rear end of the obliquely outwardly extending sole holder halves 16a, 16b. The support points 25 created by the front rollers 29 are in alignment with the tilt axes 17, so that the pushing force A originating from the heel jaws, not shown, has no influence on the lateral triggering behavior of the front jaw 16.

In den Figuren 3 und 4 bezeichnen gleiche Bezugszahlen entsprechende Bauteile wie in den Figuren 1, 1a und 2.In FIGS. 3 and 4, the same reference numbers designate corresponding components as in FIGS. 1, 1a and 2.

Im Unterschied zu dem Ausführungsbeispiel nach den Figuren 1 und 2 wird bei der Anordnung nach den Figuren 3 und 4 die den Sohlenhalter 16 nach unten drückende Kraft durch einen schrägen Abfall der Achse und damit der Kraftrichtung der Auslösefeder 26 bzw. der Zugstange 27 nach vorn und unten erzielt. Auf diese Weise besitzt die von der Auslösefeder 26 ausgeübte Kraft auch eine in Richtung der Kippachsen nach unten verlaufende Komponente, welche einen Teil der Vorspannkraft für den Sohlenhalter 16 nach unten erzeugt.In contrast to the exemplary embodiment according to FIGS. 1 and 2, in the arrangement according to FIGS. 3 and 4, the force pressing the sole holder 16 downward is caused by an oblique drop in the axis and thus the direction of force of the release spring 26 or the pull rod 27 to the front and scored below. In this way, the force exerted by the release spring 26 also has a component which runs downwards in the direction of the tilting axes and which generates part of the prestressing force for the sole holder 16 downwards.

Außerdem sind die Kippachsen 17 beim Ausführungsbeispiel nach den Fig. 3, 4 etwas gegenüber der Vertikalen in der Weise gekippt, daß sie von oben nach unten und etwas nach vorn verlaufen. Auf diese Weise erzeugt auch die vom Fersenbacken herrührende Anschubkraft A einen Teil der nach unten zur Schrägfläche 19 hinwirkenden Vorspannkraft.In addition, the tilt axes 17 in the embodiment according to FIGS. 3, 4 are tilted somewhat with respect to the vertical in such a way that they run from top to bottom and somewhat to the front. In this way, the pushing force A originating from the heel cheek also generates part of the prestressing force acting downwards towards the inclined surface 19.

In Figur 3 ist der Fall dargestellt, daß durch eine Vorlage des Skifahrers der Sohlenhalter 16 schon etwas nach unten gerutscht ist, wodurch der Anschlag 18 bereits mit der Schrägfläche 19 in Eingriff gekommen und die Seitenauslösekraft entsprechen herabgesetzt ist.In Figure 3, the case is shown that the sole holder 16 has already slipped somewhat by a presentation of the skier, whereby the stop 18 has already come into engagement with the inclined surface 19 and the side release force is reduced accordingly.

Im oberen Bereich des Vorderbackens 23 sind gegenüber dem Ausführungsbeispiel nach den Figuren 1 und 2 die Schrägfläche 19′ und der Anschlag 18′ in dem Sinne kinematisch vertauscht, daß letzterer gehäusefest und die Schrägfläche 19′ im oberen Bereich des Sohlenhalters 16 vorgesehen ist.In the upper region of the front jaw 23, the inclined surface 19 'and the stop 18' are reversed kinematically compared to the embodiment of Figures 1 and 2 in the sense that the latter is fixed to the housing and the inclined surface 19 'is provided in the upper region of the sole holder 16.

Bei der Ausführungsform nach Figur 5 ist am unteren Ende des Sohlenhalters bzw. an einer oder beiden seiner Hälften 16a, 16b ein Trittanschlag 30 vorgesehen, der mit der Unterseite der Spitze der Sohle 14 im Eingriff steht. Beim Abwärtsbewegen der Sohle 14 im Falle eines Frontalsturzes wird somit auch von der Sohle 14 selbst über den Trittanschlag 30 eine nach unten gerichtete Kraft auf den Sohlenhalter 16 ausgeübt, welche über die Schrägfläche 19 zu einer weiteren Herabsetzung der Seitenauslösekraft führt.In the embodiment according to FIG. 5, at the lower end of the sole holder or on one or both of its halves 16a, 16b, a step stop 30 is provided which engages with the underside of the tip of the sole 14. When the sole 14 is moved down in the event of a frontal fall, the sole 14 itself also exerts a downward force on the sole holder 16 via the step stop 30, which force leads to a further reduction in the lateral release force via the inclined surface 19.

Zur Schaffung einer gewünschten Reibungskompensation stehen also verschiedene Parameter und bauliche Mittel zur Verfügung, nämlich die Kraft der Auslösefeder 26 selbst, die Kraft einer besonderen Hilfsfeder 24, die Schuhdruckkraft nach oben oder unten, die Anschubkraft sowie Anschläge und Schrägflächen in unterschiedlicher Anordnung und Ausbildung.Various parameters and structural means are available to create a desired friction compensation, namely the force of the release spring 26 itself, the force of a special auxiliary spring 24, the shoe pressure force up or down, the pushing force as well as stops and inclined surfaces in different arrangements and designs.
