Description

Die Erfindung betrifft einen Skischuh entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a ski boot according to the preamble of claim 1.

Ein Skischuh mit den Merkmalen gemäß dem Oberbegriff des Anspruches 1 ist durch die EP-A-0 053 340 bekannt. Bei diesem Skischuh führen von der Schalenzunge zwei Zugelemente über von den Schwenkgelenkachsen des Spoilers gebildete Umlenkstellen zu einem an der Rückseite des Spoilers vorgesehenen Rastverstellmechanismus. Über diese Zugelemente ist die Schalenzunge mit dem Spoiler derart gekoppelt, daß eine Schwenkbewegung des Spoilers zwangsläufig eine entsprechende Schwenkbewegung der Schalenzunge bewirkt. Mittels des Rastverstellmechanismus kann die Kraft, mit der die Schalenzunge bei geschlossenem Skischuh nach hinten gezogen wird, eingestellt werden.A ski boot with the features according to the preamble of claim 1 is known from EP-A-0 053 340. In this ski boot, two pulling elements lead from the shell tongue via deflection points formed by the pivot joint axes of the spoiler to a latching adjustment mechanism provided on the rear of the spoiler. The shell tongue is coupled to the spoiler via these tension elements in such a way that a pivoting movement of the spoiler inevitably brings about a corresponding pivoting movement of the shell tongue. The force with which the shell tongue is pulled backwards when the ski boot is closed can be adjusted using the locking mechanism.

Durch die DE-B-2 231 221 ist ferner ein Skischuh bekannt, bei dem die schwenkbare Schalenzunge einen Zentralverschluß trägt, mit dem zwei vom oberen Ristbereich schräg nach unten zum Fersenbereich verlaufende Zugbänder verbindbar sind. Zum Schließen des Skischuhes müssen hierbei Haken von Zuglaschen des Zentralverschlusses in Eingriff mit Schlitzen an den freien Enden der Zugbänder gebracht werden. In entsprechender Weise ist es beim Ausziehen des Skischuhes erforderlich, nach dem Öffnen des Zentralverschlusses zunächst die Haken der Zuglaschen des Zentralverschlusses aus den Schlitzen der Zugbänder auszuhaken.From DE-B-2 231 221 a ski boot is also known in which the swiveling shell tongue carries a central lock with which two drawstrings which run obliquely downward from the upper instep area to the heel area can be connected. To close the ski boot, hooks on the pull tabs of the central lock must be brought into engagement with slots on the free ends of the drawstrings. In a corresponding manner, when the ski boot is removed, it is necessary to first unhook the hooks of the pull tabs of the central lock from the slots in the drawstrings after opening the central lock.

Der Erfindung liegt die Aufgabe zugrunde, einen Skischuh entsprechend dem Oberbegriff des Anspruches dahin weiterzuentwickeln, daß - unter Gewährleistung eines bequemen rückwärtigen Einstieges und eines druckfreien, festen Sitzes der Ferse im Innenschuh sowie einer Ausdehnungsmöglichkeit für den Fuß besonders im Ristbereich - die praktische Handhabung des Skischuhes beim An- und Ausziehen weiter erleichtert wird.The invention has for its object to develop a ski boot according to the preamble of the claim that - while ensuring a comfortable rear entry and a pressure-free, firm seat of the heel in the inner shoe and an expansion option for the foot especially in the instep area - the practical handling of the ski shoe is further facilitated when putting on and taking off.

Diese Aufgabe wird erfindungsgemäß durch das kennzeichnende Merkmal des Anspruches 1 gelöst.This object is achieved by the characterizing feature of claim 1.

Durch die feste Verbindung des Zugelementes mit dem von der Schalenzunge getragenen Zentralverschluß entfällt bei dem erfindungsgemäßen Skischuh die Notwendigkeit eines Einhängens des Zugelementes in den Zentralverschluß beim Anziehen des Skischuhes und eines Lösens des Zugelementes vom Zentralverschluß beim Ausziehen des Skischuhes.Due to the fixed connection of the tension element with the central lock carried by the tongue of the ski boot according to the invention, there is no need to hook the tension element into the central lock when putting on the ski boot and to release the pulling element from the central lock when the ski boot is removed.

Wird der Zentralverschluß geschlossen und das Zugelement dadurch angezogen, so verengt sich der Fersenraum, wobei zugleich über den Schalenhauptkörper ein in seiner Größe einstellbarer Druck auf die Ristpartie des Innenschuhes ausgeübt wird. Schwillt der Fuß bei der sportlichen Betätigung etwas an, so kann der Benutzer durch teilweises Entspannen des Zentralverschlusses dem Fuß mehr Spielraum geben.If the central lock is closed and the traction element is thereby attracted, the heel space narrows, and at the same time a pressure which is adjustable in size is exerted on the instep area of the inner shoe via the shell main body. If the foot swells slightly during sporting activities, the user can give the foot more leeway by partially relaxing the central lock.

Der in Fig. 1 dargestellte Skischuh besteht im wesentlichen aus einer Schale 1 aus steifem Kunststoff und einem Innenschuh 2 aus elastisch verformbarem Material.The ski boot shown in Fig. 1 consists essentially of a shell 1 made of rigid plastic and an inner boot 2 made of elastically deformable material.

Die Schale 1 enthält einen Schalenhauptkörper 3, eine im vorderen Bereich des Schalenhauptkörpers schwenkbar angelenkte Schalenzunge 4 und einen im Fersenbereich des Schalenhauptkörpers 3 schwenkbar angelenkten Spoiler 5.The shell 1 contains a shell main body 3, a shell tongue 4 pivotably articulated in the front region of the shell main body and a spoiler 5 pivotably articulated in the heel region of the shell main body 3.

Die Schalenzunge 4 trägt in ihrem mittleren Bereich einen Zentralverschluß 6, der mit zwei zum Fersenbereich des Schalenhauptkörpers 3 geführten Zugelementen zusammenwirkt, was anhand der Fig. 2 bis 4 noch im einzelnen erläutert wird. Im oberen Bereich von Schalenzunge 4 und Spoiler 5 ist noch ein Schaftverschluß 7 vorgesehen, von dem in Fig. 1 lediglich die Lasche erkennbar ist.The shell tongue 4 carries in its central region a central lock 6 which interacts with two tension elements guided to the heel region of the shell main body 3, which will be explained in more detail with reference to FIGS. 2 to 4. In the upper area of the tongue 4 and spoiler 5 there is also a shaft closure 7, of which only the tab can be seen in FIG. 1.

Der Spoiler 5 ist über zwei Schwenkgelenkachsen 8, 9 schwenkbeweglich am Schalenhauptkörper 3 gelagert. Diese Schwenkgelenkachsen 8 und 9 bilden zugleich die Umlenkstellen für das bzw. die Elemente, die den Zentralverschluß 6 mit dem Fersenbereich des Schalenhauptkörpers 3 verbinden.The spoiler 5 is pivotally mounted on the shell main body 3 via two swivel joint axes 8, 9. These swivel joint axes 8 and 9 also form the deflection points for the element or elements which connect the central closure 6 to the heel region of the shell main body 3.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel ist als Zugelement ein einziges durch stahldraht gebildetes Zugseil 10 vorgesehen, das vom Zentralverschluß 6 (in Fig. 2 nicht veranschaulicht) durch eine erste Öffnung 11 im Schalenhauptkörper 3 zu einer durch die Schwenkgelenkachse 9 gebildeten ersten Umlenkstelle im Schalenhauptkörper auf der einen (linken) Seite des Fersenbereiches geführt ist, von hier aus durch die genannte Öffnung 11 über die durch einen Schlitz 12 geteilte Ristpartie des Schalenhauptkörpers 3 und eine zweite Öffnung 13 im Schalenhauptkörper zu einer von der Schwenkgelenkachse 8 gebildeten zweiten Umlenkstelle im Schalenhauptkörper auf der anderen (rechten) Seite des Fersenbereiches geführt ist und das von hieraus durch die zweite Öffnung 13 zurück zum Zentralverschluß 6 läuft. Die beiden Enden des Zugseiles 10 sind fest mit dem Zentralverschluß 6 verbunden.In the embodiment shown in FIG. 2, a single pull cable 10 formed by steel wire is provided as the pulling element, which pulls from the central lock 6 (not illustrated in FIG. 2) through a first opening 11 in the shell main body 3 to a first deflection point formed by the swivel joint axis 9 Shell main body is guided on one (left) side of the heel area, from here through said opening 11 via the instep part of the shell main body 3 divided by a slot 12 and a second opening 13 in the shell main body to a second deflection point formed by the swivel joint axis 8 in the shell main body is guided on the other (right) side of the heel area and runs from here through the second opening 13 back to the central lock 6. The two ends of the pull rope 10 are fixed with the central lock 6 connected.

Fig. 1 zeigt in vollausgezogenen Linien den Skischuh im geöffneten Zustand von Zentralverschluß 6 und Zentralverschluß 7. Der Spoiler 5 läßt sich dabei gewünschtenfalls noch weiter nach hinten abschwenken. Ebenso läßt sich der Innenschuh 2 weitgehend öffnen, was im einzelnen an Hand der Fig. 7 und 8 erläutert wird. Die Schalenzunge 4 ist bei geöffnetem Zentralverschluß 6 um einen begrenzten Winkel gegenüber dem Schalenhauptkörper 3 nach oben schwerkbar (durch diese Schwenkbewegung kann die Schalenzunge 4 im Bereich des Zentralverschlusses 6 beispielsweise um ein Maß von 2 bis 6 cm angehoben werden. In dieser Lage kann der Benutzer bequem von hinten in den Skischuh einsteigen, der dann mittels des Schaftverschlusses 7 und des Zentralverschlusses 6 geschlossen wird. Dabei lassen sich die Schaftweite mittels des Schaftverschlusses 7 und die Fersenweite mittels des Zentralverschlusses 6 unabhängig voneinander einstellen.Fig. 1 shows in solid lines the ski boot in the open state of central lock 6 and central lock 7. The spoiler 5 can be swung further back if desired. Likewise, the inner shoe 2 can be largely opened, which is explained in detail with reference to FIGS. 7 and 8. When the central lock 6 is open, the shell tongue 4 can be raised upward by a limited angle with respect to the shell main body 3 (this pivoting movement allows the shell tongue 4 to be raised, for example, by a measure of 2 to 6 cm in the region of the central lock 6. In this position, the user can Comfortably step into the ski boot from behind, which is then closed by means of the shaft lock 7 and the central lock 6. The shaft width can be adjusted independently of one another by means of the central lock 6 and the shaft lock 7 and the heel width.

Wird der Zentralverschluß 6 geschlossen und das Zugseil 10 dadurch angezogen, so verengt sich der Fersenraum, wobei zugleich über den Schalenhauptkörper 3 ein in seiner Größe einstellbarer Druck auf die Ristpartie des Innenschuhes 2 ausgeübt wird. Da sich der Schlitz 12 im Schalenhauptkörper 3 beim Anziehen des Zugseiles 10 etwas verengt, erfährt der Innenschuh 2 im Bereich des Vorderfußes auch eine erwünschte seitliche Abstützung. Schwillt der Fuß des Benutzers bei der sportlichen Betätigung etwas an, so kann der Benutzer durch teilweises Entspannen des Zentralverschlusses 6 den auf den Fersenbereich und die Ristpartie ausgeübten Druck verringern und dem Fuß mehr Spielraum geben, nachdem durch teilweises Entspannen des Zugteiles 10 sich auch der Schalenhauptkörper 3 im Bereich des Schlitzes 12 mehr öffnet. Anhand der Fig. 7 und 8 wird noch erläutert, wie durch die Gestaltung des Innenschuhes 2 eine gute Anpassung des Innenschuhes an unterschiedliche Bedingungen gewährleistet ist.If the central lock 6 is closed and the traction cable 10 is thereby tightened, the heel space narrows, and at the same time an adjustable pressure is exerted on the instep area of the inner shoe 2 via the shell main body 3. Since the slot 12 in the shell main body 3 narrows somewhat when the traction cable 10 is tightened, the inner shoe 2 also experiences a desired lateral support in the region of the forefoot. If the foot of the user swells somewhat during the sporting activity, the user can reduce the pressure exerted on the heel area and the instep area by partially relaxing the central lock 6 and give the foot more leeway after the tensioning part 10 has also relaxed the main shell body 3 opens more in the area of the slot 12. With reference to FIGS. 7 and 8 it will be explained how the design of the inner shoe 2 ensures a good adaptation of the inner shoe to different conditions.

Bei dem Ausführungsbeispiel gemäß Fig. 3 ist ein einziges Zugseil 10' vom (nicht dargestellten) Zentralverschluß 6 durch eine erste Öffnung 11' im Schalenhauptkörper 3' zu einer durch die Schwenkgelenkachse 9' gebildeten ersten Umlenkstelle im Schalenhauptkörper 3' auf der einen (linken) Seite des Fersenbereiches geführt. Von hier aus läuft das Zugseil 10' über die Ristpartie des Innenschuhes 2 zu einer von der Schwenkgelenkachse 8' gebildeten zweiten Umlenkstelle im Schalenhauptkörper auf der anderen (rechten) Seite des Fersenbereiches und von hier aus durch eine zweite Öffnung 13' zurück zum Zentralverschluß. Bei diesem Ausführungsbeispiel wirkt somit der von einem Teil des gespannten Zugseiles 10' ausgeübte Druck unmittelbar auf den Innenschuh 2. Im übrigen entspricht die Funktion der des bereits anhand der Fig. 1 und 2 erläuterten Ausführungsbeispieles.In the exemplary embodiment according to FIG. 3, a single pull cable 10 'is from the (not shown) central lock 6 through a first opening 11' in the shell main body 3 'to a first deflection point in the shell main body 3' formed by the swivel joint axis 9 'on the one (left) Side of the heel area. From here, the pull rope 10 'runs over the instep area of the inner shoe 2 to a second deflection point formed by the swivel joint axis 8' in the shell main body on the other (right) side of the heel area and from here through a second opening 13 'back to the central lock. In this exemplary embodiment, the pressure exerted by part of the tensioned traction cable 10 'thus acts directly on the inner shoe 2. Otherwise, the function corresponds to that of the exemplary embodiment already explained with reference to FIGS. 1 and 2.

Bei der Variante gemäß Fig. 4 führt ein erstes Zugseil 10a vom Zentralverschluß durch eine erste Öffnung 11 des Schalenhauptkörpers 3 zur Schwenkgelenkachse 9 und von hier aus durch die Öffnung 11 zurück zum Zentralverschluß. Ein zweites Zugseil 10b läuft vom Zentralverschluß durch die zweite Öffnung 13 zur Schwenkgelenkachse 8 und von hieraus durch die Öffnung 13 zurück zum Zentralverschluß. Die Funktion entspricht dem Ausführungsbeispiel gemäß den Fig. 1 und 2.In the variant according to FIG. 4, a first traction cable 10a leads from the central lock through a first opening 11 of the shell main body 3 to the swivel joint axis 9 and from here through the opening 11 back to the central lock. A second pull rope 10b runs from the central lock through the second opening 13 to the swivel joint axis 8 and from there through the opening 13 back to the central lock. The function corresponds to the exemplary embodiment according to FIGS. 1 and 2.

Bei allen drei Varianten gemäß den Fig. 2, 3 und 4 werden die im Schalenhauptkörper 3 bzw 3' vorgesehenen Öffnungen 11, 13 bzw. 11', 13', durch die die Zugseile 10, 10' bzw. 10a, 10b durchgeführt sind, durch die Schalenzunge 4 nach außen abgedeckt.In all three variants according to FIGS. 2, 3 and 4, the openings 11, 13 or 11 ', 13' provided in the shell main body 3 or 3 'through which the traction cables 10, 10' or 10a, 10b are passed, covered by the tongue 4 to the outside.

Die Fig. 5 und 6 veranschaulichen die schwenkgelenkige Anlenkung der Schalenzunge 4 am Schalenhauptkörper 3. Da die Schalenzunge 4 nur um einen begrenzten Winkel (von beispielsweise 10 bis 25°) gegenüber dem Schalenhauptkörper 3 schwenkbar sein soll, ist die Schwenkstelle 14 als einfaches Biegegelenk ausgebildet. Zu diesem Zweck ist die Schalenzunge 4 im vorderen Bereich mit einem Schlitz 4a versehen, in den ein flacher Vorsprung 3a des Schalenhauptkörpers 3 eingreift. Ein weiterer Vorsprung 3b des Schalenhauptkörpers 3 stützt die Schalenzunge 4 auf der Unterseite ab.5 and 6 illustrate the pivotable articulation of the shell tongue 4 on the shell main body 3. Since the shell tongue 4 should only be pivotable by a limited angle (for example 10 to 25 °) relative to the shell main body 3, the pivot point 14 is designed as a simple bending joint . For this purpose, the shell tongue 4 is provided in the front area with a slot 4a, into which a flat projection 3a of the shell main body 3 engages. Another projection 3b of the shell main body 3 supports the shell tongue 4 on the underside.

Der zwischen den Vorsprüngen 3a und 3b befindliche Teil 4b der Schalenzunge 4 ist mit einem Durchbruch 4c versehen, in den eine noppenartige Verdickung 3c des Vorsprunges 3a eingreift.The part 4b of the shell tongue 4 located between the projections 3a and 3b is provided with an opening 4c into which a nub-like thickening 3c of the projection 3a engages.

Auf diese Weise ist ohne Verwendung eines Scharnieres ein Biegegelenk geschaffen, das eine begrenzte Schwenkbewegung der Schalenzunge 4 gegenüber dem Schalenhauptkörper gestattet.In this way, a flexible joint is created without using a hinge, which allows a limited pivoting movement of the shell tongue 4 relative to the shell main body.

Anhand der Fig. 7 und 8 sei nun der Innenschuh 2 näher erläutert.The inner shoe 2 will now be explained in more detail with reference to FIGS. 7 and 8.

Er enthält einen Schaft 22, der mit zwei seitlichen Schlitzen 23 versehen ist, die vom oberen Rand des Schaftes 22 ausgehen und an der Stelle 23a unterhalb der Ferse enden. Der von diesen zwei seitlichen Schlitzen 23 begrenzte mittlere und obere Bereich 24a des von oben bis unten durchgehenden hinteren Schaftteiles 24 ist gegenüber dem die Ferse umschließenden unteren Bereich 24b des hinteren Schaftteiles 24 nach hinten schwenkbar, wie in Fig. 7 mit gestrichelten Linien angedeutet.It contains a shaft 22 which is provided with two lateral slots 23 which extend from the upper edge of the shaft 22 and end at point 23a below the heel. The middle and upper region 24a of the rear shaft part 24 which runs from top to bottom and is delimited by these two lateral slots 23 can be pivoted rearwards relative to the lower region 24b of the rear shaft part 24 which surrounds the heel, as indicated in FIG. 7 by dashed lines.

Um diese Schwenkbewegung des hinteren Schaftteiles 24 gegenüber dem vorderen Schaftteil 25 zu erleichtern, schließt sich an das abgerundete untere Ende (Stelle 23a) der zwei seitlichen Schlitze 23 je ein flexibel gestalteter Zwickel 26 an. Außerdem ist die Übergangszone 27 zwischen dem unteren Bereich 24b und dem mittleren sowie oberen Bereich 24a des hinteren Schaftteiles 24 flexibel gestaltet. Diese Übergangszone 27 bildet damit gewissermaßen eine Schwenkgelenkstelle, um die der hintere Schaftteil 24 zum Einstieg in den Innenschuh nach hinten geschwenkt werden kann.In order to facilitate this pivoting movement of the rear shaft part 24 with respect to the front shaft part 25, a flexibly designed gusset 26 connects to the rounded lower end (position 23a) of the two lateral slots 23. In addition, the transition zone 27 between the lower region 24b and the middle and upper region 24a of the rear shaft part 24 is designed to be flexible. This transition zone 27 thus forms, as it were, a swivel joint around which the rear one Shaft part 24 can be pivoted backwards to get into the liner.

Die Ristpartie 28 des Innenschuhes 2 ist in vertikaler Richtung begrenzt beweglich gestaltet. Zu diesem Zweck ist im Bereich der Ristpartie 28 wenigstens eine Dehnungszone 29 vorgesehen, die vom Schaft 22 ausgeht und sich - der Schuhkontur folgend - in einem Bogen bis in den vorderen Bereich 30 des Schuhes erstreckt.The instep section 28 of the inner shoe 2 is designed to be movable to a limited extent in the vertical direction. For this purpose, at least one stretch zone 29 is provided in the area of the instep 28, which extends from the shaft 22 and - following the shoe contour - extends in an arc into the front area 30 of the shoe.

Bei dem in Fig. 7 dargestellten Ausführungsbeispiel ist zu beiden Seiten der Ristpartie 28 des Innenschuhes 2 je eine Dehnungszone 29 vorgesehen. Sie wird bei dem Ausführungsbeispiel gemäß Fig. 7 durch einen Schlitz gebildet, der sich in der durch eine gestrichelte Linie 29a angedeuteten Weise öffnen kann, so daß die Ristpartie 28 sich in die durch die gestrichelte Linie 28a veranschaulichte Form nach oben wölben kann. Dadurch wird einerseits der rückwärtige Einstieg in den Innenschuh 2 wesentlich erleichtert, und zum andern kann sich dadurch die Ristpartie 28 einem bei der sportlichen Betätigung anschwellenden Vorderfuß ideal anpassen.In the embodiment shown in FIG. 7, an expansion zone 29 is provided on each side of the instep area 28 of the inner shoe 2. In the exemplary embodiment according to FIG. 7, it is formed by a slot which can open in the manner indicated by a dashed line 29a, so that the instep portion 28 can bulge upwards into the shape illustrated by the dashed line 28a. On the one hand, this considerably facilitates the rear entry into the inner shoe 2, and on the other hand, the instep area 28 can adapt itself ideally to a forefoot swelling during sporting activities.

Bei dem in Fig. 8 in einem Querschnitt durch den Vorderfuß dargestellen weiteren Ausführungsbeispiel sind die beiden Dehnungszonen 29', die die Ristpartie 28' seitlich begrenzen, als Balg ausgebildet, wobei im Bereich dieser Dehnungszone 29' die Schaumstoffpolsterung des Innenschuhes weggelassen oder in der Wandstärke so weit verringert ist, daß die Dehnungszonen 29' eine gute Flexibilität besitzen. Beim Einstieg in den Innenschuh sowie bei Anschwellen des Fußes bei der Benutzung kann sich die Ristpartie 28' nach außen verformen, wie durch die gestrichelte Linie 28'a angedeutet ist.In the further exemplary embodiment shown in a cross section through the forefoot in FIG. 8, the two expansion zones 29 ', which laterally delimit the instep area 28', are designed as bellows, the foam padding of the inner shoe being omitted in the area of this expansion zone 29 'or in terms of the wall thickness is so far reduced that the expansion zones 29 'have good flexibility. When entering the inner shoe and when the foot swells during use, the instep area 28 'can deform outwards, as indicated by the dashed line 28'a.

Im Unterschied zu den dargestellten Ausführungsbeispielen kann auch nur eine einzige Dehnungszone 29 bzw. 29' vorgesehen werden, die dann zweckmäßig in der Längsmitte der Ristpartie 28 bzw. 28' angeordnet wird.In contrast to the exemplary embodiments shown, only a single stretch zone 29 or 29 'can also be provided, which is then expediently arranged in the longitudinal center of the instep part 28 or 28'.

Die Dehnungszone 29 bzw. 29' erhält zweckmäßig eine Bogenlänge von 8 bis 25 cm, vorzugsweise von 14 bis 20 cm.The expansion zone 29 or 29 'expediently has an arc length of 8 to 25 cm, preferably 14 to 20 cm.

Der Abstand der beiden Dehnungszonen 29 bzw. 29' beträgt - über den Umfang der Ristpartie 28 bzw. 28' gemessen - zweckmäßig 5 bis 16 cm, vorzugsweise 8 bis 12 cm.The distance between the two expansion zones 29 and 29 ', measured over the circumference of the instep area 28 and 28', is expediently 5 to 16 cm, preferably 8 to 12 cm.

Die zwei seitlichen Schlitze 23 im Schaft 22 enden zweckmäßig 6 bis 14 cm, vorzugsweise 8 bis 11 cm, oberhalb der Sohle des Innenschuhes 2.The two lateral slots 23 in the shaft 22 expediently end 6 to 14 cm, preferably 8 to 11 cm, above the sole of the inner shoe 2.

Der in den Fig. 7 und 8 dargestellte Innenschuh 2 eignet sich besonders zur Verwendung in dem Skischuh gemäß den Fig. 1 bis 6, da die Gestaltung des hinteren Schaftteiles 24 und der in vertikaler Richtung beweglichen Ristpartie 28 einerseits den rückwärtigen Einstieg in den Skischuh erleichtern und andererseits über den Zentralverschluß 6 und die Zugseile 10,10' bzw. 10a, 10b eine ideale Anpassung der Ristpartie des Innenschuhes an den Fuß des Benutzers (unter Gewährleistung eines gleichbleibend guten Fersensitzes) ermöglichen. Es sei jedoch hervorgehoben, daß grundsätzlich auch traditionell ausgebildete Innenschuhe (entweder mit einer Zunge in der Ristpartie oder mit einer durchgehend geformten Ristpartie) bei dem erfindungsgemäßen Skischuh verwendet werden können.The inner boot 2 shown in FIGS. 7 and 8 is particularly suitable for use in the ski boot according to FIGS. 1 to 6, since the design of the rear shaft part 24 and the instep part 28 movable in the vertical direction on the one hand facilitate the rear entry into the ski boot and on the other hand, via the central lock 6 and the pull cables 10, 10 'and 10a, 10b, an ideal adaptation of the instep area of the inner shoe to the user's foot (while ensuring a consistently good heel fit) is made possible. However, it should be emphasized that traditionally designed inner boots (either with a tongue in the instep area or with a continuously shaped instep area) can also be used in the ski boot according to the invention.
