The shaft (4) consists of at least one front flap (5) and a rear flap (6). The flaps are secured to the shell by swivelling axes. Closure devices and adjustment devices are arranged on the individual parts or flaps of the skiboot. The shell cover (3) extends to an end of the front flap (5) opposite to the sole (25) and is encompassed in the region of the instep by a support surface (24) connected to the shaft (4). An instep cover (20) of the shell cover (3) pivots relative to a covering part (19) for the interior part of the foot which forms part of the shell cover, about an axis (21) perpendicular to a longitudinal direction (26) of the sole and approximately parallel to the sole (25).

Description

Ski boot with a shell and a multi-part shaft

The invention relates to a ski boot with a shell and a multi-part upper with a shell lower part which, on a side facing away from the sole, has a longitudinal slit extending from the area of a shoe tip into the heel area and with a slot located on the shell lower part from the area of the shoe tip up to the shaft above the longitudinal slot, in particular integrally connected to the lower shell part of the shell cover at least one front flap and a rear flap which form the shaft and are fastened to the shell via swivel axes and with locking devices and with adjusting devices between the individual parts or flaps of the ski shoe.

A wide variety of designs for ski shoes have already become known, some of which are provided with a front entry, a rear entry or also with a so-called central entry. These different types of entry should on the one hand make getting in and out of the ski shoe as comfortable as possible and, on the other hand, should enable a favorable transfer of forces between the foot and the ski when the ski shoe is closed.

Various embodiments of ski boots of this type, which can be opened in a large area to make it easier to get in and out of them, can be found in DE-OS 23 41 658, AT-PS 331 672 and DE-OS 34, among others 29 237 known. These known ski boots have in common that a shell cover around one in the area the shaft, which is arranged transversely to the longitudinal direction of the sole, can be pivoted relative to the sole, so that an area between a tailgate of a shaft and an instep area is exposed for easier insertion and removal. In some versions, the shell cover can be swiveled forward so that the entire footbed is accessible from above. Although it is easier to slip in and out by such a configuration of the ski shoes, the movement sequence with the ski shoe closed is unsatisfactory, particularly with regard to the pivoting of the shaft relative to the shell, and occurs especially with those ski shoes which the upper shell part can be pivoted up over the entire length, sealing problems in the transition area between the lower shell part and the pivotable shell cover.

Another embodiment of ski boots is known for example from DE-AS 21 28769, CH-PS 642520 and from DE-OS 3429891. In these known ski boots, the tailgate of the upper is designed in such a way that it can be pivoted forwards by a larger angle than the front flap. This pivoting makes it easier to get in through the larger free space in the heel area. In order to enable the tailgate to be pivoted to such a large extent, a corresponding arrangement of the pivot points is required, as a result of which the movement of the shaft during skiing cannot usually be optimally adapted to the movements of the lower leg relative to the foot.

The present invention has for its object to provide a ski boot of the type mentioned, which allows easy slipping in and out, and in the closed state allows a good fixation of the foot in the shoe even at different angular positions between the foot and the lower leg. In addition, it should be possible to adapt the shoe well to the transition area between instep and shin base. If necessary, it should also be possible to move the reference movements between the Steam the shell and the shaft. Furthermore, it should preferably also be possible to switch off this damping device when the shaft is closed.

This object of the invention is achieved in that the shell cover extends into the area of an end of the front flap of the shaft facing away from the sole and engages around a support surface connected to the shaft in the instep area and in that an instep cover of the shell cover relative to a forefoot cover the same can be pivoted about an axis running transversely to a longitudinal direction of the sole and approximately parallel to the sole.

The interaction of the instep cover of the shell cover with the support surface connected to the shaft advantageously achieves a relative relative movement of the instep cover and the support surface approximately perpendicular to the sole when the lower leg is pivoted forward, so that an exact movement over the entire forward movement is achieved Leadership of the instep remains intact. At the same time, this embodiment of the ski boot also ensures that when the upper or the ski boot is opened, the front flap can be pivoted forward independently of the instep cover and the movement of the back cover in the direction of the upper is released by pivoting the support surface away. This makes it possible for the instep cover to be pushed upwards by the foot when it slips out of the shoe, and as a result the foot can be moved as freely as possible between the instep and heel while pivoting the tailgate. A so-called "central entry" is achieved by pivoting the front and rear flaps in opposite directions and the possibility of deflecting the instep also in the direction of the front flap. Without additional mechanical means, such as cable pulls or the like, an adjustment device for heel adjustment and the instep cover can be brought into a desired position adapted to the anatomical shape of the foot when the shaft is closed, and the instep cover due to the support surface. It is surprising here that by such a solution the pivot axis for the shaft approximately can be arranged in the ankle area or in the area of the ankle axis, as a result of which the swivel area of the shaft can simply follow the natural movements of the lower leg relative to the foot. The adaptation of the instep cover to the different operating conditions, such as open front flap or closed front flap, is facilitated by the axis around which the instep cover is pivotably mounted and, above all, a targeted movement path is impressed on this part, which guides the foot between the heel without play and instinct favors.

According to a further embodiment, it is possible for the shell part and the shell cover to form separate components, as a result of which the design of the pivot axis can be more easily adapted to the respective load and the desired movement sequence.

However, it is also advantageous if the forefoot cover and the instep cover of the shell cover are formed in one piece, since this can simplify the effort for the manufacture of the instep cover according to the invention.

According to another embodiment, it is possible for a weakening line to be arranged between the forefoot cover and the instep cover, which is preferably formed by a cross-sectional weakening, which can save additional mechanical effort for the manufacture of the axle.

However, it is also possible for the cross-sectional weakening to be formed by a groove-shaped recess in the forefoot cover which runs transversely to the longitudinal direction of the sole, the groove bottom of which has a shorter length than a width of the forefoot cover, since the elasticity inherent in this, when using suitable materials, is simultaneous can be used for pivoting the parts to one another.

But it is also possible that a pivot arrangement is arranged between the forefoot cover and the instep cover, which one Axis forming pivot axis, whereby the resistance to forward pivoting of the front flap can be kept approximately the same over the entire pivoting range.

According to another embodiment variant, it is provided that the forefoot cover and the instep cover are pivotably mounted independently of one another on the pivot axis of the pivot arrangement, whereby it is possible to arrange the bearing point of the pivot axis of the pivot arrangement directly in the individual covers.

According to another embodiment, it is provided that the swivel arrangement is arranged between the instep cover and the lower shell part, as a result of which good anchoring can be achieved without stressing the forefoot cover.

It is advantageous if the weakening line or the axis is fixed in an optionally pre-adjustable position in the longitudinal direction of the sole relative to the lower shell part with the closure device closed, since this allows the movement of the instep cover in the region of the pivot axis or weakening line to follow exactly a predefined movement path and this can nevertheless absorb loads occurring in the longitudinal direction of the ski shoe.

However, it is also possible for the line of weakness or the axis to be arranged directly adjacent to one another in the direction of the shoe tip and, in particular, by a buckle arrangement, to be fixed relative to the lower shell part by the closure device, as a result of which a good seal between the forefoot cover and the Lower part of the shell, and at the same time a fixation of the line of weakness or the pivot axis in the longitudinal direction can take place. This additional support means that the instep cover does not have to transmit all the forces acting on it in the longitudinal direction of the sole and may therefore be of weaker construction.

According to a further embodiment, it is provided that the pivot axis forming the axis is mounted in the lower shell part, where is possible by good anchoring of the swivel axis and a relative movement of the instep cover relative to the lower shell part can ensue.

Furthermore, it is also possible that the closure device e.g. the buckle arrangement is arranged in the groove-shaped depression and the line of weakness is formed by the transition between the groove bottom and a groove flank facing the instep cover. The desired movement geometry can be achieved with simple means by using an edge of the molded part immediately adjacent to the closure device as a weakening line.

However, it is also possible for the shell cover to be connected to the lower shell part in the region of the toe of the shoe by means of a holding device, as a result of which the assembly of the shell cover is facilitated.

Also advantageous is an embodiment according to which the holding device is fixedly arranged in the sole longitudinal direction on the lower shell part, since such an embodiment allows the instep cover to be supported over the shell lid in the longitudinal direction of the sole.

According to another embodiment, it is provided that the shell cover can be pivoted in the area of the holding device about an axis running approximately parallel to the axis, whereby the removal of the inner shoe and additionally the slipping in and out of the shoe can be facilitated.

However, it is also advantageous if the instep cover is preferably guided between the axis and the heel area in a slide track which is arranged in the lower shell part, since the additional guidance of the instep cover in the slide track reduces the load on the weakening line and the desired movement sequence of the instep cover can be maintained even under heavy loads.

However, it is also possible for the backdrop track to be Longitudinal slots arranged richly from two side walls of the lower shell part are inclined, which are inclined towards the sole by a small angle of between 5 ° and 30 °, preferably 15 °, in the direction of the shoe tip. As a result, the end of the instep cover facing away from the line of weakness or axis can be moved in a direction corresponding to the desired sequence of movements when loaded by the instep or the shin attachment and, especially under load, cannot deflect laterally or in the undesired direction.

Furthermore, it is also possible for the slide tracks to be designed in the form of a circular arc and the center of which forms the axis, whereby tension in the instep cover and thus excessive stresses in the axis can be avoided.

According to another embodiment, it is provided that the backdrop track is designed in the form of a circular arc and that its center is in the area of the holding device of the shell cover, so that the shell cover is not additionally stressed, particularly when it slides in and out of the ski boot.

However, an embodiment variant according to which the slide track has two circular-arc-shaped sections with different radii is also advantageous, since this allows the instep cover to move with the ski shoe closed with respect to the line of weakness or axis while opening the shaft or the ski shoe for slipping out or in, the further movement of the instep plate can take place with reference to the further articulation point, for example the shell cover.

According to another variant, it is also possible for a width of the slide track to be greater than a diameter or a width of guide elements guided therein, since this compensates for the movement in the case of different pivot radii of the instep plate by the difference in dimensions between the Guide organs and Ku¬ lissenbahnen can take place. According to another embodiment of the invention, it is provided that the front and rear flaps are mounted on the two side walls of the lower shell part, preferably for both common pivot axes, so that a movement of the shaft part corresponding to the movement of the lower leg with respect to the foot is carried Advantage is achievable.

It is advantageous if the front flap is approximately semi-cylindrical in shape and has a U-shaped cutout extending centrally from the lower front end towards the upper front end, since this results in a correspondingly high degree of mobility of the front flap relative to the front flap Shell or the shell lid is possible.

According to a further preferred embodiment, it is provided that a U-shaped cutout, in particular a tapering slot extending in the direction of the upper end, is arranged and ends at a distance below the upper end. This solution allows a greater free space for closing the shaft, so that it can be better adapted to the different anatomical course of the foot in the lower leg area immediately following the foot.

It is also advantageous if a base of the U-shaped cut-out forms the support surface, since when the ski boot is closed, the shaft part, that is to say the front flap, can also be used to support and guide the instep plate.

Furthermore, it is also possible for the front flap to support a support plate, the front edge of which faces the lower front end forms the support surface, as a result of which the front flap does not have to be formed so solidly and additional shin protection is provided by using a support plate.

However, it is also possible for the front flap to consist of two front flap parts, each of which is placed on one of the two in the the pivot axes arranged on the opposite side walls is mounted since this further facilitates the adaptation to different lower leg diameters.

It is advantageous here if the front flap parts are connected to one another via the support plate, since the necessary strength of the front flap can be achieved by using the support plate.

However, an embodiment is also possible in which the support plate is adjustable in the circumferential direction of the front flap or the front flap parts at least along a part of guide arrangements extending on both sides of the cutout and / or the slot relative to the front flap or the front flap parts, as a result of which in a stepless adjustment of the shaft width to different lower leg dimensions is possible in a certain area.

Furthermore, it is also possible that closure devices formed by buckle arrangements are provided between the front flap or the front flap parts and the tailgate and that a

The arrangement of the buckle supports the support surface, the support surface preferably being arranged on a support plate connected to the buckle arrangement, since as a result the position of the support plate can also be exactly adapted to the setting of the shaft defined by the buckle arrangement.

It is also advantageous if the buckle arrangement is anchored in the tailgate and preferably passes through it, since this ensures good anchoring and guidance of the buckle arrangement in the region of the tailgate.

It is also advantageous if the buckle arrangement has a catch band which is connected to the tailgate by means of an eccentric buckle with an actuating lever and a carrying strap and the locking strap is assigned a locking member which in turn is anchored in the tailgate via a carrying strap, because that makes one sensitive adjustment of the tension forces acting on the foot or the closing forces to adapt the shaft to the shape of the lower leg is possible.

According to a further embodiment variant, it is provided that the carrying strap for the locking member and the detent strap is in one piece, so that it can be found with a fastening point for the carrying strap, preferably in the region of the tailgate.

It is also possible, however, that holding members are assigned to the carrying strap in the region of the two side walls of the tailgate and that the holding members are preferably adjustable in the direction of the longitudinal axis of the sole, thereby achieving a central alignment of the buckle and thus a central tension of the shaft.

According to another embodiment variant, it is provided that the carrying strap penetrates the side wall of the tailgate in the area of the holding members and that the holding members are connected to an adjusting device which can be adjusted in the longitudinal direction of the sole, whereby a centering of the buckle arrangement is additionally possible.

However, it is also possible for the holding member to be provided with a locking member for the carrying strap, which creates the prerequisite that a part of the carrying strap extending into the interior of the ski boot can be used for further functions.

According to another embodiment it is provided that a support flap for the heel is arranged on the supporting band section running between the two holding members in the interior of the shaft, whereby the supporting band can not only be used for the buckle arrangement but also for heel support and with a suitable design when the buckle arrangement is released and thereby when the front and rear flaps are opened, the heel support is released, thereby achieving an even greater freedom for slipping in and out of the ski boot. Another further development provides that the buckle arrangement comprises an eccentric buckle with catch straps arranged at both ends and that separate locking members are assigned to them in the region of the tailgate, the eccentric buckle and / or the catch straps opposite the front flap are adjustably fastened in these, so that the eccentric buckle can always be locked in the middle.

It is advantageous here if the two locking members are arranged, in particular, sunk in the side walls of the tailgate, since jamming in the area of the locking members is avoided.

However, it is also possible for the front flap and the rear flap to be connected to the side walls of the lower shell part by separate pivot axes, whereby the opening width of the front and tail flap can be increased further in accordance with the arrangement of the two separate pivot axes .

It is also advantageous, however, if the tailgate is mounted on the front flap supported on the lower part of the shell by means of pivot axes, since in this embodiment a uniform pivot axis can be achieved in the closed state, for example in the region of the ankle pivot axis, whereas when the ski boot is opened, one compared to an arrangement of the front and rear flap on a common axis, a larger opening width and thus a more comfortable slipping in and out is made possible.

Another embodiment provides that the shaft is connected to an adjusting device for the template or template damping, which is arranged between the front flap and / or the tailgate and the lower shell part, and which has a damping device formed, for example, by a spring, whereby after a corresponding damping of the template is possible when the shaft is closed. Furthermore, it is advantageous if the front and / or tailgate is guided in a guide device of the adjusting device so as to be adjustable relative to the latter and that a releasable coupling device is arranged between the front and / or or the tailgate and the adjusting device. If required, the function of the damping device is switched off via the releasable coupling device, the movement of the front or tailgate when the ski boot is open is not impeded by this damping device, and this part can be pre-positioned in the closed state, while still in the open state the freedom of movement is given and it is thus easier to slip out and in.

According to another embodiment variant, it is provided that the setting device for adjusting the template and / or template damping of the shaft is arranged in the instep area between the lower shell part and the front flap, which simplifies operation with less stress on the the front flap is reached with the buckle arrangements connecting the tailgate.

Furthermore, it is also possible for a spring element as a damping device to be arranged in the overlap area of the front flap and the lower shell part, which spring element is located from an area of a side wall closest to the sole over the shell cover in the area of the opposite side wall in the area of the sole extends and is held in a holding device in the region of its ends facing the sole. The advantage of this solution lies in the fact that such a spring element has a very low construction and thus an optically advantageous shape of a ski boot can be achieved and at the same time the advantages of a damping device arranged in this way can be achieved with simple operation.

However, it is also advantageous if the holding device has a bore penetrating the lower shell part approximately parallel to the sole, into which legs of the spring element which run approximately parallel to the sole engage, and the holding device further unites between the bore and the shell cover comprises an abutment arranged on the shell lower part between the spring element and a toe and the spring element is fastened in a guide plate which forms a guide device with guide slots in the housing of the adjusting device, the guide slots of the housing on the The lower part of the front flap facing the shell is arranged and the locking pin of the coupling device penetrates the front flap and the eccentric lever is arranged on the side of the front flap facing away from the lower part of the shell, since this enables the spring element to be held securely and also to absorb large damping forces. In spite of this, the size and the number of openings in the area of the front flap are kept small, so that despite the various adjustment and adjustment options, the boot is tight.

However, it is also possible for the locking pin to be assigned a bore in the guide plate, as a result of which a simple connection can be established between the front flap and the lower shell part, which also enables the adjustment movements to be damped to be transmitted without play.

According to another development, it is provided that the abutment has a height which is greater than a distance between the mutually facing surfaces of the lower shell part and the shell cover and the abutment formed with a round or polygonal cross section is guided in a groove of the front flap facing the lower shell part is, wherein the groove is arranged on a connecting line between the toe and the tailgate, whereby the part required as an abutment for the spring element can also be used to limit the maximum adjustment path of the front flap relative to the lower shell part. As a result, it can be found with a smaller number of individual parts, so that the assembly costs are not disadvantageously changed when using such an adjustment device. It is furthermore advantageous if the abutment for the spring element is arranged on an actuator, for example an adjusting strip of an adjusting device, since the suspension characteristics can thus be easily adapted to different conditions, for example in the case of deep snow or hard slopes, when the template moves.

A lower overall height of the adjusting device is further achieved if the actuator is formed by an expansion-stiff but flexible adjustment strip, perpendicular to the surface of the lower shaft part, which in a longitudinal slot in the lower shell part in a opposite direction via a pin preferably formed by the abutment the shoe axis is arranged at an inclined plane, nevertheless high support forces can be absorbed by the abutment since it can be supported in a longitudinal slot in the lower shell part via the pin.

According to a further embodiment, it is provided that the actuator is coupled to an adjustment drive of the adjustment device, whereby rapid adjustment of the actuator can be achieved.

It is furthermore advantageous if the adjustment drive is provided with a threaded spindle with two opposing threaded sections, which is mounted in the front flap and is coupled to an actuating element arranged outside the front flap, which from an actuating position projecting relative to the front flap into an abutting position on the front flap can be swiveled in this lowered rest position, if necessary, since a change in the damping characteristic or spring characteristic of the spring element can be achieved without manipulations on the front flap and in any position of the front flap relative to the lower shell part.

In addition, it is advantageous if the actuating member has different actuating positions with respect to the free flap, since this enables the actuating member to be locked in a simple manner, so that a preselected setting is also possible during the use of the ski boot, i.e. the skiing maintains its attitude.

But it is also possible that the actuating member forms the eccentric lever of the coupling device and the locking pin is slidably mounted on the threaded spindle in the longitudinal direction thereof and is provided with an annular groove facing the threaded sleeve, in which guide pin e.g. Engage thrust pins which are connected in motion with a push rod which is displaceable in the longitudinal direction inside the threaded sleeve and which is rotatably mounted on the eccentric lever with its other end, which makes it possible to change both the suspension and damping characteristics with a single common actuating member , as well as the locking and unlocking between the spring element and the front flap.

Another development provides that the spring element is connected to a coupling part in which the bore for the locking pin is arranged, the bore being through the threaded spindle! the adjustment device is penetrated. As a result, large forces can be transmitted from the locking pin to the spring element, and it can still be found with a low overall height.

Finally, it is also possible for the spring element to be U-shaped or C-shaped and for one leg to be connected to the guide plate and another leg or a base of the C-shaped spring element to the lower shell part, as a result of which a lower overall height can also be designed having spring elements can be used in conjunction with the adjusting device.

For a better understanding of the invention, it is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

In Fig. a ski boot 1 according to the invention is shown, the shell of which consists of a lower shell part 2 and a shell cover 3. A shaft 4 consists of a Frontkl appe 5 and a Heckkl appe 6. The Frontkl appe 5 is over in the side walls 7 of the

Shell lower part s 2 supported pivot axes 8 pivotally mounted. The tailgate 6 is connected via its own also in the side walls 7 of the lower shell part 2 pivoted axles 9 articulated to the lower shell part 2.

To close the shaft 4 or the lower shell part 2, locking devices are arranged. The closure devices consist of buckle arrangements 10, 11. Each buckle arrangement 10, 11 comprises an actuating lever 12 which can be pivoted about an axis 13. The actuating lever 12 of the buckle arrangement 10 is further coupled with a catch 14, which in turn interacts with a ratchet part 15 by means of drivers, for example an identical toothing. The ratchet part 15 is connected to cable assemblies 16, which are guided in brackets formed by receiving openings 17 on the front flap 5 and anchored in the tailgate 6. By adjusting the actuating lever 12 from the drawn in full lines from the front flap 5 to the projecting position into a position against the front flap 5, the cable pulls 16 are tensioned, so that the front flap 5 and the tailgate 6 are in a locked position locked together. An adjusting device 18 for the template is connected to the tailgate 6. As can also be seen from this illustration, the shell cover 3 consists of a forefoot cover 19 and an instep cover 20. The forefoot and instep cover 19, 20 are ver relative to one another about an axis 21 which runs approximately parallel to the swivel axes 8, 9 swiveling. To this end, the forefoot and instep cover 19, 20 are mounted in a swivel arrangement which has a swivel axis forming the axis 21. This can be supported in the lower shell part 2 or only connect the forefoot to the instep cover 19, 20. As indicated by dashed lines, the instep cover 20 extends into the area above the shin base at the foot so as to enable the foot to be firmly seated in the ski boot.

To prevent the instep cover 20 from exerting strong pressure against the instep cover 20 in the direction of a shoe tip 22, a base of a U-shaped element arranged in the front flap 5 is provided

Cutout 23 formed as a support surface 24.

Is the shaft 4 closed by the buckle arrangement 10 by a relative movement of the lower leg in the direction of the foot, i.e. e.g. When a skier kneels down and moves forward, the pressure of the instep of the wearer of the ski shoe on the instep cover 20 increases. The latter now tries to dodge in the direction of the tip 22 of the shoe. Excessive deformation of this instep cover 20 in the direction of the shoe tip 22 is now counteracted by the support surface 24 which overlaps the instep cover 20. The

The pivoting path of the instep cover 20 is designed such that it becomes larger as the template increases and the forward movement of the front flap 5 increases. With a corresponding design of the U-shaped cutout 23 in the region of the front flap 5, it can further be achieved that when the front flap 5 is pivoted forward with the buckle arrangement 10 opened, the base of the U-shaped cutout 23 extends into the region of the axis 21 can be pivoted at the front. The axis 21 runs parallel to a sole 25 and transversely to a longitudinal direction 26 of the sole, which is shown schematically by an axis extending from the tip of the shoe 22 into a heel region 27. As further indicated by dashed lines, the shell cover 3 extends along and above a longitudinal slot 28 of the shell lower part 2, which runs between a shoe tip 22 and the heel area 27.

In order to hold a leg 29 schematically indicated by thin lines free of pressure, an inner shoe 30 made of soft material, for example an open-cell PU foam with textile or leather lining on the inside or outside, is between the leg 29 and the shell and the shaft 4 arranged.

Another advantage of the illustrated ski boot 1 is that after opening the buckle arrangement 10, the front flap 5 of the shaft 4 can be moved forward about the pivot axes 8 in the direction of the front buckle arrangement 11 or the toe 22, depending on the arrangement the pivot axes 8, the support surface 24 allows the front flap 5 to pivot into the area between the axis 21 and the toe 22. This enables the instep cover 20 to move almost freely about the axis 21, so that when the leg 29 slips out of the ski shoe 1, the instep cover 20 can be pivoted away from the instep area in the direction of the shoe tip 22. As a result, the tension that is important in a ski boot between the instep area and the heel area can be removed, so that it is easier to slip in and out. In addition, the tailgate 6 can be pivoted rearward about the pivot axes 9, as is also indicated by schematic lines, which also releases the heel fixation and makes it even easier to slip in and out. The front flap 5 and the rear flap 6 can therefore be adjusted in the manner of a central lock in the opposite direction in the sole longitudinal direction 26, so that the greatest possible distance between the instep area and the heel area is achieved. In the case of leg 29 located in the ski boot, on the other hand, by closing the front and rear flaps 5 and 6 in opposite directions, the heel adjustment to the heel area and the instep cover 20 is made via the support surface 24 into the desired area which locks this foot area Position pivoted. A ski boot 1 designed in this way thus enables the slip area to be released centrally without complex cable pull mechanism between the individual parts of the front flap 5 and the rear flap 6, and a firm holding and fixing of the leg 29 in the ski boot 1.

Another embodiment variant of a ski boot 1 is shown in FIG. This also comprises a lower shell part 2, a shaft 4 formed from a front flap 5 and a rear flap 6 and an inner shoe 30 arranged in the interior of the lower shell part 2 or the shaft 4. The lower shell part 2 is again provided with a longitudinal slot 28, which is arranged extends from the toe 22 into the heel region 27. This longitudinal slot 28 is closed by a shell cover 3 which extends above the longitudinal slot 28. The shell cover 3 consists of a forefoot cover 19 which extends from the area of the toe 22 to an imaginary axis 21. An instep cover 20 connects from there. The axis 21 is formed by a weakening line running transversely to the longitudinal direction 26 of the sole and parallel to the sole 25. This line of weakness arises from the fact that a cross section of the shell cover 3 between the forefoot cover 19 and the instep cover 20 is reduced. For this purpose, the shell cover 3 is provided with a groove-shaped recess 31 in the forefoot cover 19. A groove bottom 32 of the recess 31 has a shorter length 33 than a width 34 of the forefoot cover 19 that is directly adjacent to it. In addition, a buckle arrangement 11 is provided in the region of this groove-shaped recess 31, with which the groove bottom 32 is in its position opposite the shell lower part 2 can be fixed. In the present case, a line of weakness 35 is formed through the transition region or the edge between the groove bottom 32 and a groove flank 36. Thus, the toe cover 20 can be pivoted about this line of weakness 35 in the longitudinal direction 26 of the sole. In order to ensure pivoting in the desired direction, the instep cover 20 is also connected to guide elements 37, which are guided in the side walls 7 of the lower shell part 2 and are guided in an adjustable manner approximately perpendicular to the sole 25. In connection with the design of the slide track 38 and in cooperation with the weakening line 35, the instep cover 20 can now be pivoted approximately in a circular path about the axis 21.

The movement of the instep cover 20 is limited by the support surface 24, which is arranged on a support plate 39, which in turn is attached to the front flap 5.

The support plate 39 can now be selected in accordance with the demands of the material stiffness, the thickness and the shape, since elastic properties such as are required, for example, in the pivotable front flap 5 are not required. Thus, this support plate 39 can be solid, especially in the area of the support surface 24, so that the instep cover 20 cannot deflect in the direction of the shoe tip 22 even under heavy loads. However, it is advantageous here if the support plate 39 is simultaneously used to distribute the clamping forces of the buckle arrangements 10 in the region of the shaft 4. In order to divide the clamping force of the buckle assemblies 10 into the desired areas, the support plate 39 can be provided with guide ribs 40, 41 for guiding carrying straps 43, 44 receiving the actuating lever 12 or a locking member 42, or a detent band 45 connected to the actuating lever 12 serve. Due to the rigid design of the support plate 39 and a corresponding design of the U-shaped cutout 23 and a tapered slot 47 extending in the direction of an upper front end 46, this support plate 39 can be made at any inclination relative to the lower leg take in adaptation to the shape of the lower leg.

3 to 5, which show different views of the same ski boot 1 as in FIG. 2, the adjustment of the shaft width in the region of the foot drawn in thin dash-dotted lines in all the figures can be seen better. In the instep area of the foot, two different anatomical options are purely schematic and in some cases strong for a better understanding of the proportions exaggerated with dash-dotted lines and dash! shown lines. A foot shape corresponding to the dash-dotted line corresponds to a position of the support plate 39 as shown in full lines. During the formation of a foot corresponding to the dashed line with a high instep and a relatively straight approach of the shin corresponds to the position of the support plate 39 shown with dashed lines. As can be seen further from this illustration in FIG. 3, both the support plate 39 has a compensating effect and also the instep cover 20, since this increases with a higher instep of the leg 29, for example by bending around the weakening line 35 instead of Position drawn in full lines which corresponds to a dash-dotted course of the leg 29 assumes the position indicated by dashed lines. The fixation of this line of weakness 35 in the direction of the toe 22 and the height-based guidance in

The lower shell part 2 along the slide track 38 makes it possible to adapt the position of the instep cover 20 to the instep course or the transition between instep and shin on the respective leg 29.

This adjustment is not least made easier by the fact that

Support plate 39, as can be seen better from FIGS. 4 and 5, is supported in the upper end of the V-shaped slot 47 via a pin 48 in the direction of the upper end 46. Furthermore, the support plate 39 is on guide pins 49.50 in the area on both sides of the U-shaped cutout and / or the V-shaped slot

47 extending guide assemblies 51 slidably mounted. As a comparison of the two representations in FIGS. 4 and 5 now shows, a cross section of the shaft 4 can be achieved by changing the U length of the front flap 5. For example, by tightening the sole closer to the sole 25

Buckle arrangement 10 has a cross-sectional width 52 in which the guide pins 49 and 50 are located approximately in the middle of the guide arrangements 51 to a cross-sectional width 53 as drawn in full lines in FIG. 5, the guide pins 49, 50 then being separated from one another distant end areas of the

Guide assemblies 51 are located. By using the guide - Pin 49, 50 and pin 48, which supports this support plate in the direction of the upper end 46 of front flap 5, can be adjusted according to a predeterminable spatial guideway. This prevents undesired tension or deformation of the front flap 5. The reduction of the cross-sectional width 52 to the cross-sectional width 53 is made possible by bringing the two flanks of the V-shaped slot 47 into a position parallel to one another, as can be seen from FIG. Due to the fixed cross-sectional width 52 in the area of the upper end 46, the deformation takes place only in the area closer to the transition area between the shin and instep, in which experience has shown that, for anatomical reasons, people have different or strongly changing foot cross sections. The advantage of this solution is that a smaller cross-sectional width 53 in the area of the buckle arrangement 10 closer to the support surface 24 almost does not increase the tension in the area of the buckle arrangement 10 closer to the upper front end 46. In the case of the ski shoes used hitherto, the lack of flexibility of the front flap 5 in the circumferential direction leads to an inexact adaptation of the ski shoe to the transition area between the instep and the shin attachment, which means that when the skier bends his knees, the shin strikes the upper front end 46 of the front flap 5 presses or higher surface pressures than desired occur there and this pressure is perceived as unpleasant or often leads to an overload of the skin surface (pressure points, blistering). In this respect, in addition to its support function with the support surface 24, this support plate 39 also has a function that transmits the clamping forces over a large area to the shin area, which is achieved by a correspondingly coordinated design of the support plate 39 and the front flap 5. Further advantages of this design result from the interaction of the support surface 24 with the instep cover 20 by the swiveling of the instep cover 20 about the axis 21 shown in FIG. 4 or the weakening line 35 in the edge region of the depression 31, namely, the lower leg of the leg 29 is pivoted forward about the ankle joint in the direction of an arrow 54, for example when the skier kneels, there is automatically a Load in the heel area 27, ie the heel has a tendency to lift off the sole 25, as a result of which the instep cover 20 is put under greater stress by the instep of the leg 29. Under load, the instep cover 20 now tries to deflect in the direction of the support plate 39, but is retained by the support plate 39 to an extent corresponding to the forward pivoting of the front flap 5 over the support surface 24. This prevents the leg 29 or the heel from lifting too far from the sole 25, or slipping out of the adjustment device 55, indicated by dashed lines, for holding or adapting the heel or in the region of the archilles tendon, and thereby the Lateral guidance of the leg 29 with respect to the ski boot 1 is lost. A loss of this fixation leads to the fact that the rotational movements of the leg 29, for example when swinging, can no longer be transmitted to the ski to the necessary extent, from which the guidance of the ski suffers. Due to the increased resistance which is opposed to deformation of this instep cover 20 via the support plate 39 and the support surface 24, the transmission of the rotational movement of the leg 29 to the ski is favored. It is also important here that the instep cover 20 is fixed in the longitudinal direction - arrow 57 - of the ski boot 1 via the forefoot cover 19 and a holding device 56.

As shown in FIGS. 2 to 4, this holding device 56 consists of a tab 58 formed on the lower shell part 2 and provided with a locking lug 59 at its end facing the heel area 27. This can also be integrally formed on the tab 58. A bracket 60 of the holding device 56 is supported on the tab 58 and prevents further slipping in the direction of the shoe tip 22. The locking lug 59 prevents the forefoot cover 19 from being pulled out or pulled from the lower shell part 2. However, this holding device 56 is flexible for pivoting perpendicular to the sole 25. When the buckle arrangements 11 are open, the forefoot cover 19 can be swung up with the instep cover 20 for better access and for easier slipping in and out. When slipping in and out, the full length of the slide track 38 in the lower shell part 2 can be used be when the guide member 37 which is connected to the instep cover 20 is adjusted in the upper region of the slide track 38. As a result of this mobility in the holding device 56, the entire articulation for utilizing the full adjustment path in the link path 38 through the weakening line 35 or in the region of the axis 21 does not have to be applied, but it can be done especially when the ski boot is opened when the buckle arrangements 11 are open Part of the pivoting movement of the shell cover 3 takes place via the holding device 56, as will be explained in more detail with reference to FIG. 9.

It can further be seen from the illustration in FIG. 4 that, in order to stiffen the forefoot cover 19 between the depressions 31 for the buckle arrangements 11, the raised areas can be reinforced by internal ribs 61.

The end of the instep cover 20 facing the upper end 46 is provided with V-shaped slots 62, so that if the front flap 5 is deformed when the cross-sectional width 52 or 53 is narrowed, it can adapt to different cross-sections without causing wrinkles or the application of punctual pressure forces in the area of the shin.

The arrangement of the front flap 5 and the rear flap 6 on pivot axes 63, 64 is also shown from the lower part of FIG. The pivot axis 63 is fastened in the side wall 7 and the pivot axis 64 in a side wall 65 of the lower shell part 2. The pivot axis 64 is formed by an outer retaining washer 66 and an inner anchoring washer 67. The retaining washer 66 is provided with a through hole and the anchoring washer 67 with an internal thread. A screw 68 is inserted into the through hole, which screw is screwed into the internal thread of the anchoring disk 67 and braces the retaining disk and the anchoring disk 67 against one another. Because the retaining washer 66 and the anchoring washer 67 abut against one another with their end faces, the screw 68 can be tightened as much as desired, but remains sufficient movement space for the pivoting of the front flap 5 and the rear flap 6 relative to the lower shell part 2.

The pivot axis 63 is formed opposite to the canting adjustment of the shaft 4 relative to the lower shell part 2 or the sole 25. This canting setting with which a shaft axis 69 can be adapted to the anatomical conditions of a leg 29 is achieved by changing a distance 70 between the pivot axis 63 and the upper end 46 in the region of the side wall 7. As a result, the shaft axis 69 can be pivoted by an angle either in the direction of the side wall 7 or in the direction of the side wall 65, as indicated by two-dot-dash lines in FIG. This enables the geometry of the ski shoe 1 to be easily adapted to 0 or X legs. A retaining washer 71 is provided with an elongated hole 72 in which the screw 68 is slidably guided. An anchoring washer 73, which is similar to the design of anchoring washer 67 with an internal thread, has a pin 74 projecting in the direction of the holding washer 71, on which a clamping plate 75 is provided with teeth 76 on its end facing the front flap 5 , is led.

The teeth 76 of the clamping plate 75 are assigned a guide slot 77 for the clamping plate 75 in the surface of the front flap 5 facing them, the surface of which is also provided with teeth 76.

The adjustment of the shaft 4 in relation to the lower shell part 2 with an adjusting device 78 consisting of the aforementioned parts for the lateral inclination of the shaft 4 now takes place as follows:

The screw 68 is turned out of the anchoring disk 73 so far that the teeth 76 of the clamping plate 75 and the front flap 5 disengage. The front flap 5 can then be adjusted together with the holding disk 71 mounted in a recess 79 in the same in the direction of the lower shell part 2 or in the direction of the upper end 46. Is the desired angle that the anatomical If the conditions of the foot are best achieved, the desired position can be fixed by tightening the screw 68 and tightening the teeth 76 against each other. For simultaneous adjustment of the tailgate 6 together with the tailgate 5, a guide bore 80 is arranged in the tailgate 6, which is rotatably mounted on an annular shoulder 81 of the tailgate 5. As a result, when the front flap 5 is adjusted relative to the screw 68, the rear flap 6 is also taken along accordingly, so that canting between these two flaps is avoided.

Of course, the holding disk 66 can also be guided in a recess 79, so that parts protruding from the surface of the front flap 5 are avoided. Likewise, the tailgate 6 can also be guided in the front tailgate 5 in the region of the pivot axis 64, in that the tailgate 6 is provided with a guide web 82 which extends over a circular section and to which a circular opposite 83 of the tailgate 6 is assigned. In addition, a stop 84 is formed on the front flap 5, which is guided in a slot 85 in the tailgate 6. A maximum relative movement of the front flap 5 and the rear flap 6 with respect to one another is limited by this slot 85. The arrangement of the slot 85 and the stop 84 assigned to it can also be seen from FIG. 3.

4 also shows that the instep cover 20 can be provided with reinforcing ribs 86 which are adjacent to the weakening line 35, so that the swiveling of the instep cover 20 with respect to the forefoot cover 19 actually only in the area of the weakening line and not in the immediately adjacent areas.

Openings 87 are further provided in the tailgate 6, in which a carrying strap 43, which can be connected to an actuating lever 12 or a catch strap 45, penetrates the tailgate 6. As in the area of the support band 43 closer to the sole 25 is shown, this can be fixed by means of a fixing pin 88 against a relative movement relative to the rear door 6.

Of course, it is also possible for this fixing pin 88 not to be visible from the outside but to be attached to the inside of the tailgate 6, this fixing being particularly important when the carrying band 43 is as shown in FIG .12 is shown, runs through the rear door 6 and is connected in the region of the opposite side wall with a locking band or a locking element 42.

Various positions of the shaft 4 in relation to the lower shell part 2 are shown in FIGS. In this different position it is assumed that the setting device 18 for the template is set to its maximum range of movement, so that the entire pivoting path of the shaft 4 relative to the

The lower part of the shell can be used. It should be noted that the design of the ski boot in FIGS. 6 to 8 corresponds to that described in detail in FIGS. 2 to 5. Furthermore, the buckle arrangements 10 have been omitted and the front flap 5 has been partially torn open in order to better represent the different relative positions between the instep cover 20, the support plate 39 and the lower shell part 2. It is assumed that the buckle assemblies 10 are closed and tightened during these movements.

6 shows the shaft 4 in its rear end position, in which a lower leg 89 has only a small template compared to a foot 90. In this position, the guide member 37 is located in the area of the sliding track 38 closest to the sole 25, since the instep cover 20 is pushed back and held in this position via the support surface 24 of the support plate 39, so that the leg 29 and / or the transition area between the lower leg 89 and foot 90 is given. If the template of the lower leg 89 is now reinforced as shown in FIG. 7, the pressure of the lower leg 89 on the front flap 5 increases, as a result of which the shaft 4 swivels and the support plate 39 shifts in the direction of the toe 22. As a result, the instep cover 20 also has the possibility of giving in under the pressure in the instep area or in the transition area between the foot 90 and the lower leg 89.

The ski boot is shown in FIG. 7 when the leg 29 is stronger than in FIG. 7. The guide member 37 is located in the slide track 38 in a position remote from the sole 2. Due to the effect of the support surface 24, however, the instep cover 20 is only granted as much space as is absolutely necessary for the prevention of the lower leg 89 relative to the foot 90. Although the movement of the lower leg 89 can take place, at the same time the foot 90 cannot move forward in the instep area to such an extent that, for example, the heel 91 lifts off the sole 2, or from an adjusting device 55 for holding the heel 91 in the area of the Achilles tendon can dodge. The release of the movement of the instep cover 20 to the anatomically necessary extent by the support surface 24 shifting in accordance with the forward inclination of the lower leg 89 thus also allows the foot 90 to be properly clamped in the shell lower part 2 up to the extreme presentation, as shown in FIG In this situation as well, it is possible to transmit the rotational movement of the leg 29 to a ski connected to the ski shoe 1 without problems.

8 shows an extreme template position of the lower leg 89 of the leg 29. As can be seen, the support plate 39 and the instep cover 20 are shifted extremely forward, whereby, like the dash-dotted line that shows the leg 29 in the instep area, adequate support and stabilization of the instep cover 20 is also provided by the support surface 24 even in the extreme presentation is. The instep cover 20 is located in its uppermost position furthest from the sole 25 of the ski boot, as can be seen from the sliding track 38 and the guide member 37. Due to the spatially defined displacement of the instep cover 20 due to the guidance of the guide member 37 in the cooling track 38 in cooperation with the weakening line 35 with increasing presentation of the lower leg 69, the instep cover 20, as can be seen from a comparison of FIGS. 6 to 8, shift in the direction of the upper front end 46 of the front flap 5. This prevents the instep plate 20 from buckling inside the shoe, that is to say in the area of the support surface 24, which would produce an undesirable pressure point on the leg 29 or in the instep area.

9 shows the ski boot 1 according to FIGS. 2 to 8 in the open position. The buckle assemblies 10, of which both the carrying strap 43 and the detent strap 45 and the actuating lever 12 can be seen, are open and the front flap 5 and the rear flap 6 are at their maximum both in the direction of the shoe tip 22 and in the direction of the heel region 27 End position swings. The leg 29 is shown in a position in which it must pass the narrowest cross section between the instep cover 20 and the adjusting device 55 for heel adjustment. It proves to be advantageous that the central opening - the front flap 5 and the tailgate 6 can be pivoted about the same amount in the direction of the toe 22 and the heel area 27 - the support plate 39 the movement of the instep cover up to the Area of the weakening line 35 is released, so that the force exerted on the instep cover 20 via the instep of the foot adjusts the top of the slotted track 38 up to the stop of the guide member 37 the most distant from the shoe sole 25. The instep cover 20 is unlocked when the front flap 5 is opened by simultaneously pivoting the support plate 39 away, so that the support surface 24 is disengaged. Likewise, the adjusting device 55 is brought into its farthest position from the instep cover 20 by pivoting the tailgate 6 backward. As can be seen, in order to effect this release of the instep cover 20 and the release of the adjusting device 55, no additional mechanical parts, cable pulls or the like are required, but this release takes place imperatively through the arrangement and assignment of the individual parts of the ski shoe in the above-mentioned sensible manner and way. The arrangement of the pivot axes 63, 64 in the region of the ankle axis proves to be very advantageous, since the shaft 4 can be opened centrally from this area. On the other hand, it can be seen from the representations in FIGS. 6 to 8 that this matching of the position of the ankle axis with the pivot axes 63, 64 results in a movement of the shaft 4 which is most anatomically adapted to the movement of the lower leg 89 and thus the friction forces which occur and resistance in the shoe against the pivoting of the shaft 4 can be reduced. As further shown in this figure, the adjusting device 18 for fixing the template of the shaft 4 in its open position is also shown, for which purpose a locking lever 92 is pivoted into an open position. The function of this setting device will be explained in more detail below with reference to FIG. 10.

One advantage of this embodiment of the ski boot according to the invention is, however, that the assignment of the support surface 24 surrounds the instep cover 20 so that it can be made relatively flexible, soft and elastic in its area adjoining the weakening line 35 . The adjustment along the desired spatial adjustment path is nevertheless precisely defined by the line of weakness 35, the guide members 37 and the support surface 24. At the same time, the support surface 24, in cooperation with the instep cover 20, forms a tight seal between these parts over the entire range of motion when the shaft 4 is closed, so that no snow or the like can penetrate into the interior of the ski boot 1 in this area.

This resilience and elasticity has the further advantage that the instep cover 20, even when the guide members 37 are at the end of the slide track 38, has a certain resilience due to the inherent elasticity, especially when the leg 29 slips in and out.

In order to achieve a movement path corresponding to the different movement states of the rear cover 20, it is as for example deviating from the guide tracks 38 in FIGS. 2 to 8 in FIG. 9, it is shown that this guide track can be curved according to different radii, a section 93 being curved in a radius 94, the center of which forms the weakening line 35. A section 95 adjoining it is curved according to a radius 96, which corresponds to a distance between the guide track 38 and an axis 97 about which the forefoot cover 19 or the shell cover 3 can be pivoted. This axis 97 forms the holding device 56 for the shell cover 3 with respect to the lower shell part 2. As a result, when the support plate 39 swings forward a great deal and the clearance thus obtained between the support surface 24 and the instep cover 20, the instep cover 20 is first in the area of the weakening ¬ line 35 deformed to the maximum extent, as long as the guide member 37 moves in section 93, and then lifted around the axis 97 during the entire shell cover 3, the instep cover is guided in section 95.

In addition, it should be noted that, as shown, for example, in the illustration in FIG. 6, an angle 98 between a perpendicular to the sole 25 99 and a central axis 100 of the slide track 38 is a small angle, for example preferably between 5 ° and 35 °, in particular 15 ° includes. This angle 98 is achieved with the shaft in the rear end position, with the buckle arrangements 10 closed, in which case the guide member 37 mostly abuts the end region of the sliding track 38 closest to the sole 25.

10 shows the setting device 101 for setting the template of the shaft 4, of which only the tailgate 6 can be seen, on a larger scale. This adjusting device 101 is intended to hold the leg 29 in the heel area 27, so that the leg is clamped between the heel area 27 and the instep. This clamping is intended to ensure that rotational movements of the leg 29 are transmitted exactly to the ski boot 1, so that these movements can be transmitted on a ski 102 connected to the ski boot 1. In the approach Richly the Achilles tendon a support tab 103 is arranged just above the heel, which is mounted to adapt to the different inclinations on an approximately parallel to the sole 25 of the ski shoe and transverse to the sole longitudinal axis of rotation 104. The axis of rotation 104 is fastened in a housing part 105 of the setting device 101 for the template. The housing part 105 is mounted so as to be adjustable in a guide 106 in the direction of a double arrow 107. The guide 106 is arranged in a bearing body 108. The bearing body 108 can be rotated about an axis 109 which is arranged in the tailgate 6. Furthermore, a fixing device 110 is provided on the bearing body 108, which has a screw bolt which can be adjusted perpendicularly to the guide 106 via an adjusting wheel and with which the housing part 105 can be fixed in its position with respect to the bearing body 108. The housing part 105 has a guide plate 111 which, together with guide slots 112 in a housing 113 of the adjusting device 101, form a guide device. The housing 113 is articulated in the lower shell part 2 via an axis 115 via a damping device 114. In order to fix the housing part 105 and the housing 113 in a certain relative position to one another in which the tailgate 6 is in its rear end position - as shown for example in FIG. 6 - a releasable coupling device 116 is arranged. This consists of an eccentric lever 117, a locking pin 118 and a compression spring 119, which in the present case is designed as a spiral spring. The eccentric lever 117 is rotatably mounted on a pivot axis 120 passing through the locking pin 118. By pivoting the eccentric lever 117 from the position drawn in full lines, in which the locking pin 118 engages in a bore 121 of the guide plate 111, into the swiveled up position drawn with dashed lines, the locking pin 118 is - as also indicated with dashed lines - from the hole 121 pulled out. This has the effect that the housing part 105 with the guide plate 111 connected to it in motion is freely displaceable along the guide slot 112, bypassing the damping device 114. The tailgate 6 can thus be in any position relative to the lower shell part 2 be pivoted. If, on the other hand, the locking pin 118 is snapped into the guide plate 111, the housing 113 and the housing part 105 form a rigid unit, the position of which is fixed by a stop 123 arranged on a threaded rod 122, which can be formed by an adjustable nut. In the present case, the threaded rod 122 is provided with a bearing eyelet molded onto it or screwed onto it, which is supported on the axis 115. Due to the effect of the damping device 114 formed by the threaded rod 122, the stops 123 and 124 and a compression spring 125, the housing 113 is in full

Lines drawn at rest. If the shaft 4 is now moved forward in the direction of an arrow 126 when the shaft is closed, i.e. that the lower leg 89 moves in the direction of the shoe tip 22 when the person kneels, this forward movement is delayed or dampened by the compression spring 125. Depending on the suspension characteristic of this compression spring 125, which can be formed by a spiral spring, the resistance to be overcome is smaller or greater. In addition, the damping characteristics of the compression spring 125 can be increased by the stop 124, that is to say the turning of the screw nut in the direction of the stop 123, or reduced in the case of an adjustment in the opposite direction. At the same time, the adjustment of the stop 24 can also be used to determine the setting for the template limitation opposite the stop 123. This results from the longitudinal dimension of the compressed compression spring 125 and the position of the stop 124.

It is of course possible within the scope of the invention to replace the compression spring 125 by any other damping device, for example a gas spring, elastic materials such as plastics or rubber by leaf spring assemblies or the like or, for example, also by torsion bars.

Likewise, the fixing device 110 of the setting device 101 can also be designed in accordance with all the possibilities available in the known prior art. Among other things, it is also possible Lich that tooth segments 127 are arranged on the housing part 105 in the region of the guide 106, as indicated schematically. A gear wheel 128 can be assigned to these tooth segments, which, as indicated schematically by dashed lines, can be connected, for example, to a stepping motor or any other motor 129. As a result, the adjustment of the support tab 103 of the heel adjustment can be carried out, for example, via push buttons or remote control.

The advantage of the adjusting device 18, above all of the coupling device 116 integrated in this, is that after unlocking the coupling device 116 a very large relative movement between the lower shell part 2 and the tailgate 6 is possible, as a result of which the and shown in FIG described wide opening positions can be achieved.

The combination of the setting device 18 and the setting device 101 shown in FIG. 10 merely represents a preferred further development of the present invention. Of course, it is also possible to omit the setting device 101 and to remove the housing part 105 without interposing the guide 106 and fixing device. direction 110 to connect with the tailgate 6.

Another embodiment of an adjusting device 101 for heel adjustment is shown in FIG. To adapt the support tab 103 to the leg 29, a drive shaft 130 is mounted in the lower shell part 2 of the ski boot 1. An eccentric cam 131 is arranged on this drive shaft 130 and connected to it in a rotationally fixed manner. The support bracket 103 is articulated to the cam 131 via an axis 132. The cam 131 can be pivoted via an actuating lever 133 connected in a rotationally fixed manner to the drive shaft 130, so that it can be adjusted in this area between the positions drawn in full lines and the dashed lines in order to adapt to the respective course of the leg 29. Such a setting device 101 can of course also be used together with the setting device 18 for document damping. Another advantage of this adjusting device 101 is that the drive parts, in particular the cams 131, are accommodated below the tailgate 6 and thus protected from damage from the outside, and the tailgate 6 does not have to be slotted to arrange them, so that there is a risk of moisture entering or the like. is also lower. In the illustrated embodiment, the support tab 103 is also shown lying directly against the leg 29.

Another embodiment variant of an adjusting device 134 and a buckle arrangement 135 is shown in FIGS. 12 and 13. Thus, the adjusting device 134 for positioning a support strap 103 for heel adjustment consists of a buckle arrangement 135 connected to the support strap 103, which is connected to a carrying strap 137 via a rivet 136. This support band 137 is connected to a holding member 139, for example, by screws 138. Depending on the position of this holding member 139 in the longitudinal direction 26 of the sole, the support tab 103 is spaced more or less from the tailgate 6 and can thus be adapted to different anatomical conditions of the leg 29 in the area of the Achilles tendon or in the heel area 27. As indicated schematically, a plurality of bores 140 can be provided in the holding member 139 in order to assume various intermediate positions. This setting can also be made in that the holding member 139 is provided with a toothing 141, which cooperates with a toothing 142 which is arranged in a recess 143 in the tailgate 6. The holding member 139 can be fixed via a tensioning screw 144 when the teeth 141 and 142 are in engagement. In order to enable the tightening screw 144 to be rotated from the outside, the nut provided on the inside is anchored in the tailgate 6 in a rotationally fixed manner. By using the toothing 141, 142 and the relative adjustment between the holding member 139 and the tailgate 6 that is possible as a result, a sensitive adjustment of the support bracket 103 is possible.

However, as shown in the lower part of FIG. 12, this support bracket 103 can also be used to adjust a carrying strap 145 if, for example, the adjustment of the support bracket 103 is carried out via the Screw 138 and the holes 140 takes place. It is thus possible to center an eccentric buckle 146 arranged in the central region of the support plate 39 on a longitudinal axis of the shoe center, so that the tailgate 6 and the front flap 5 are closed essentially centrally. However, in order, for example, to be able to use the holding member 139 to position the support tab 103 and still be able to align the eccentric buckle 146 with a shoe axis or longitudinal axis of the shaft center, it is possible to connect the holding member 139 to a locking element T47, which is used to fix one with the eccentric buckle 146 detent band 45 is used. This version is shown as a variant in the upper half of FIG. Of course, it is possible to provide the eccentric buckle 146 instead of the carrying strap 145 in both end areas with a detent strap 45 and also to arrange such a locking member 147 in the area of both holding members 139. As a result, a completely flexible adjustment of the eccentric buckle 146 can be achieved.

This centric pulling action, which is exerted on the support plate 39 in the direction of an arrow 148, is therefore important since

Tilting of the support plate 39 with respect to the front flap 5, which consists of two front flap parts 149, 150 in FIG. 13, is avoided. The connecting link between the two front flap parts 149 and 150 is formed exclusively by the support plate 39, so that the front flap parts 149, 150 could be deformed differently in the event of an eccentric pull through the buckle arrangement 135. However, the same advantage of the central pull has a particularly advantageous effect when the support plate 39 is used in conjunction with the configuration of the front flap 5 as described in FIGS. 2 to 9, since the pin 48 and the guide pin 49 and 50 cannot constrain and tilt in the guide assemblies 51. However, this also more precisely defines the function of the support surface 24 and its position relative to the instep cover 20 or the weakening line 35.

In Fig.13 it is further shown that to adjust the movement of the Instep cover 20 at the different swivel positions of the shaft 4, the slide track 38 can have a greater width 151 than a width or a diameter 152 of the guide member 37 which can be displaced in this slide track 38. As a result, the position of the instep cover 20 can adapt to the different radii of movement , namely depending on whether the instep cover 20 pivots about the weakening line 35 or about the holding device 56 of the shell cover 3, as well as adapting to a straight course of the sliding track 38.

FIG. 14 shows a preferred embodiment of an adjusting device 153 in connection with the use of a support plate 39, with which an adjustment to different courses of the shinbone can take place. Above all, this adjusting device 153 enables the use of the instep cover 20 in cooperation with the support surface 24 of the support plate 39 and thus the same movement mechanism as this, using the preceding figures in conjunction with the weakening line 35 or the axis 21 ¬ was written. Between the instep cover 20 and the support plate 39, a wedge cushion 155 can be adjusted approximately parallel to the support plate 39 in a guide slot 154 via an adjusting device 153 formed by a screw 156 and an actuating wheel 157. For this purpose, the screw 156 is motionally connected to the wedge cushion 155. If the screw 156 is now moved in the direction of the sole 25 by turning the fixed actuating wheel 157, the pressure point or the course of the instep cover 20 is shifted in the direction of the sole 25 and at the same time a distance 158 to the lower shell part 2 or also reduced to the tailgate 6 arranged above, whereby a concave transition region 159 between the lower leg 89 and the foot can also be compensated.

At this point it should be expressly pointed out that the anatomical course of the foot and individual parts of the ski shoe in the various exemplary embodiments shown in this application have been shown purely schematically and in many cases exaggerated in the proportions and sizes by the function and mode of action of the individual adjusting devices or the movement sequence of the individual shoe parts when the foot is moving can be more clearly illustrated.

Furthermore, the individual setting devices 18, 55, 101, 134 and 153 can be interchanged in any manner and used in any combination in a ski boot 1. In addition, the design of these adjusting devices 18, 55, 101, 134 and 153 can form an independent and independent invention without the inventive formation of the instep cover 20 in cooperation with the support surface 24 or the shell cover 3. However, it should be noted that the combination of the adjusting devices described with the instep cover 20 formed in the manner described above, using a weakening line 35 and / or an axis 21, brings a multitude of further advantages which relate to their use in connection with whose features according to the invention appear particularly preferred.

FIGS. 15 to 17 show, on a larger scale and schematically, a possible embodiment of the one in FIG. buckle assembly 10 shown. A support frame 160 of the buckle arrangement 10 is fastened to the front flap 5 with rivets 161, as indicated schematically. However, it is also possible to arrange this support frame on the support plate 39. In the support frame, a detent band 162 is guided, which runs between the base plate connected to the front flap 5 and the ratchet part 15. This is articulated via a push rod 163 to the actuating lever 12, which in turn is rotatably mounted on the support frame 160 via an axis 13. Furthermore, the catch 14 can be pivoted about an axis 164 on the support frame 160. The catch can also be adjusted with a slot 165 along a bolt 166. The catch 14 is held in the position shown in full lines in FIGS. 16 and 17 by means of a compression spring 167. To unlock it, it can be pivoted up against the action of the compression spring 167, as shown in FIG. 15, whereby when the actuating lever 12 is pivoted into the position shown in FIG shown position also the ratchet part 15 is lifted off the detent band 162 and thus teeth 168 and 169 of the ratchet part 15 and the detent band 162 disengage. Thus, in the position shown in FIG. 15, the detent band 15 can be pushed back and forth as desired. After releasing the catch 14 and swiveling the actuating lever 12 forward as shown in FIG. 16, the teeth 168 and 169 of the catch band 162 and the ratchet part 15 and the catch 14 engage. Through several successive movements of the actuating lever 12 from the position shown in FIG. 16 to the position shown in FIG. 17, the detent band 162 can be displaced in the direction of an arrow 170, the actuating lever 12 being pivoted back out of the position shown in FIG. 17 in the position shown in FIG. 16, the detent band 162 is held in its position by the detent 14.

This makes it possible with simple means to provide a large adjustment path for the detent band 162, but this detent band 162 can also be formed, for example, by any other arrangement such as, for example, toothed racks or the like. It is also possible, in various positions, as indicated schematically in FIG. 16, to hook in cable pulls 171, which like cable pull 16 in FIG. For example, connect the front flap 5 and the tailgate 6 together. However, any transmission element can be used between this ratchet arrangement and the parts that can be moved relative to one another, such as front flap 5 and tailgate 6. It is also possible to have two such buckle arrangements 10, 135 parallel to one another in the manner shown in FIG. The arrangement shown is to be provided, the one buckle arrangement being used for tightening in the area of the buckle arrangement closer to the upper front end 46 of the front flap 5 in FIG. 2 and the second buckle arrangement being used for tightening at the level of the buckle arrangement 10 arranged below in FIG Can be found. The advantage of the buckle arrangement 10 as shown in FIGS. 1 and 15 to 17 as a possible exemplary embodiment is that the force can be applied from top to bottom, that is to say in a very favorable direction, and thus high forces without Torsion of the body, such as with buckles in the area of the tailgate 6 or in the area of the side walls is required can be applied.

Of course, the buckle arrangement 10 as shown in FIGS. 1 and 15 to 17 can also form the subject of an independent invention, since the advantages achieved thereby with regard to a central pull when closing the shaft 4 in connection with that in the direction of the sole directional actuation offer significant advantages over the currently known buckle arrangements, which are arranged transversely to the shaft direction or in the region of the tailgate 6. Of course, it is also possible to use such buckle arrangements with actuation in the longitudinal direction 26 of the sole in the area of the shell cover 3 or the forefoot cover 19.

Furthermore, it is also possible in connection with the features according to the invention which arise from the interaction of the support surface 24 with the rivet cover 20 and the weakening line 35 or the axis 21, any type of adjusting devices for the documents, for example to be used in the area of the front flap 5.

The canting setting is also the same, i.e. the setting of the side inclination of the shaft with respect to the shell can be selected as desired. As variants for such setting devices, reference is made to the AT-PSen 378897, 370954, 370956, the EP-OS 171 384, the EP-Patent to el fertil 85890152 and 85890153 and the DE-OS 2807348.

18 and 19 show the ski boot 1, which consists of the lower shell part 2 with the sole 25, the side walls 7 and the shell cover 3 formed in one piece with the side walls 7, as well as the one which can be pivoted about a pivot axis 8 relative to the lower shell part 2

Shaft 4 with a front flap 5 and a tailgate 6 is made.

The front flap 5 and the tailgate 6 can be brought into a fixed position relative to one another via buckle arrangements 11. In order to limit the forward movement or the relative movement between the shaft 4 and the lower shell part 2 or in an unintended walking position prevents and in a driving position damped by a damping device 114, an adjusting device 18 for the template is arranged between the front flap 5 and the lower shell part 2. This consists of a coupling device 116, of which an eccentric lever 117 of the locking pin 118 and a spring element 172 forming the damping device 114 is shown.

As can be seen from the drawing, the spring element 172 is arranged in that region of the lower shell part which is covered by the front flap 5. The spring element 172 consists of an approximately U-shaped bracket, each of which has legs 173 at its two ends which face away from one another in the region of the side walls 7 and which engage in bores 174 in the lower shell part 2 which form part of the holding device 175. This holding device 175 also includes abutments 176, for example molded or fastened to the lower shell part 2, which is arranged between the spring element 172 or the toe 22. If the eccentric lever 117 is moved into a walking position, the locking pin 118 is moved so far away from the lower shell part 2 that the locking pin 118 is located above the spring element 172. In this position, the front flap 5 or the shaft 4 can be moved freely about the pivot axis 8. In order to prevent the front flap 5 from moving forwards or backwards over the overlap region with the lower shell part 2, the abutment 176 or the pin has a height 177 which is greater than a distance 178 between the mutually facing ones turned surfaces of the lower shell part 2 and the front flap 5, as can be seen better from Fig. 19.

The pin of the abutment 176 engages in a groove 179 of the front flap 5, which is arranged on the side facing the lower shell part 2. The range of movement or adjustment of the front flap 5 relative to the lower shell part 2 is limited by a counter bearing 180 of the groove 179.

Is the eccentric lever 117 in its dashed lines indicated position, that is, pivoted into the driving position, the locking pin 118 approaches the lower shell part 2 in such a way that when the shaft 4 moves, it engages in the bore 121 of the guide plate 111 which is connected to the spring element 172. For this purpose, it is under a prestress directed against the guide plate 111, which can be applied by means of a spring element.

If the locking pin 118 is engaged in the bore 121, the front flap 5 is connected in motion to the lower shell part 2 via the spring element 172 and the front flap 5 is thereby damped in its movements relative to the lower shell part 2. If a counter bearing 180 is arranged on the side of the spring element 172 facing the tailgate 6, then the movements from a defined central position in the direction of the tailgate 6 can also be damped accordingly. Depending on the distance between the locking pin 118 and the counter bearing 180, the damping effect can be stronger or weaker.

20 and 21 show another embodiment of an adjusting device 18 designed according to the invention for the template or template damping, in which the damping behavior of a spring element 172 can be changed by an adjusting device 181.

The spring element 172 used in this exemplary embodiment is that which has already been shown in FIG. 18 and has been described in more detail. The same reference numerals are therefore used for the same parts. The spring element 172 is arranged in that area which is covered by the front flap 5. It consists of an approximately U-shaped bracket, each of which has legs 173 at its two ends facing away from one another in the region of the side walls 7, which are suspended in the lower shell part 2. In order to prevent the front flap 5 from pivoting too far towards the rear flap 6, a slot guide shown in FIG. 19 can be provided in the front flap 5, where in which the pin engaging in the groove 179 can be independent of the abutment 176. In this context, it is of course also possible to provide a corresponding groove in the lower shell part 2 and to mount a pin engaging in this groove in the front flap 5. If this pin is adjustably arranged in the front flap 5 in a longitudinal slot, it is possible to prevent the maximum end positions of the front flap. If two independently adjustable pins are provided, the front and rear end positions of the front flap can be set independently of one another. This can also be achieved, for example, by the housing 113 being adjustable relative to the front flap 5. This adjusting device comprises a threaded spindle running parallel to the sole 25 with opposing threads, with a traveling nut 183 being arranged on each of the threaded sections 182 and being connected in motion with an adjusting strip 184. A pin 185 forming the abutment 176 is provided on the adjusting strip 184, against which the spring element 172 is supported. The adjustment strip 184 is guided in a recess or a groove 186 in the lower shell part 2. As a result, the pin 185 forms a fixed abutment against deformation of the spring element 172 under the action of the locking pin 118.

The structure of the coupling device 116 can be seen better from FIG. This comprises an eccentric lever 117, which is arranged on the surface facing away from the lower shell part 2 and which has a

Pivot axis 120 is motionally connected to the locking pin 118. The pivot axis 120 is mounted eccentrically on the eccentric lever 117, so that when the eccentric lever 117 is drawn in full lines, the locking pin 118 passes through the front flap 5 and the two-part housing 113 of the coupling device 116 arranged on the side facing the lower shell part into a guide plate 111 is sufficient, which is adjustably guided in guide slots 112 of the second part of the housing 113 arranged on the side of the front flap 5 facing the lower shell part 2. The guide plate 111 is provided with a bore 121 into which the locking pin 118 engages and thus establishes a movement connection between the front flap 5 and the guide plate 111 with the spring element 172. The locking pin 118 is supported in the housing 113 by a compression spring 119, which presses the locking pin 118 relative to the housing 113 in the direction of the lower shell part 2. If the eccentric lever 117 is pivoted into the position drawn in full lines and the locking pin 118 is not in a position covering the bore 121, pivoting of the front flap 5 or of the shaft 4 and a relative displacement between the Front flap 5 and the guide plate 111 automatic locking of the locking pin 118 in the bore 121 can be achieved.

By turning or pivoting the eccentric lever 117 into the position shown in dashed lines in FIG. 20, the locking pin 118 is raised against the action of the compression spring 119 and pulled out of the bore 121. As a result, the free relative mobility between the front flap 5 and the lower shell part 2 is achieved.

22 and 23 show another embodiment of an adjusting device 18 between a front flap 5 and a lower shell part 2. An approximately C-shaped metal bracket is again provided as the spring element 172, the legs 173 of which engage in bores 174 of the lower shell part 2. The pin 185 forming the abutment 176 is arranged on adjusting strips 184 which run between the lower shell part 2 and the front flap 5 and each with a traveling nut 183 which are mounted on two threaded sections 182 and 187 with opposite threads, for example a right-hand and a left-hand thread connected. The two threaded sections 182 and 187 are arranged on a threaded sleeve 188, which is provided with recesses 189 for coupling to the eccentric lever 117 and between the eccentric lever 117 and the threaded section 187 penetrate the lower shaft part 2 and its opposite end in a likewise in Lower shaft part 2 arranged bearing 190 is supported.

Longitudinal slots 191 are arranged in the threaded sleeve 188, through which a guide pin 193 arranged in a push rod 192 projects, which engages in a groove 194 of the locking pin 118. The guide pin 193 is prestressed in the direction of the threaded section 187 via a compression spring 119. Depending on the position of the eccentric lever 117, the push rod 192 can now assume a different relative position with respect to the threaded sleeve 188 and accordingly the locking pin 118 engages in the bore 121 of a coupling part 195 which is connected in motion to the spring element 172. If, on the other hand, the eccentric lever 117 is pivoted downward against the lower shell part 2 in the illustration shown in FIG. 22, the locking pin 118 moves completely out of the bore 121. This makes the front flap 5 of that

The spring element 172 is uncoupled and can be pivoted unhindered relative to the lower shell part 2.

On the other hand, this uncoupled position is already shown in full lines in FIG. 23, in which case the locking pin 118 has already emerged from the bore 121 of the coupling part 195. Free movement of the shaft 4 or the front flap 5 with respect to the lower shell part 2 is now achieved.

Of course, it is also possible to manufacture the coupling device 116 with the push rod 192 while omitting the threaded sleeve 188 and to provide no or another known adjusting device 181 for changing the damping characteristics. Furthermore, it is also possible to provide any other type of adjustment device for the damping properties.

It is also advantageously possible to use as spring elements 172 such as are described in our parallel patent applications A 1960/87 and A 1961/87, the legs deforming there either with the housing 113 or the

Guide plate 111 must be brought into motion and thus form the abutments via which the front flap 5 is supported on the lower shell part 2 when the coupling device 116 is in engagement. The subject matter of the two older own patent applications A 1960/87 and A 1961/87 is thus made the disclosure content of the present application.

24 shows a spring element 172 which is formed by a U-shaped elastic spring clip 196. This is inserted into a recess 197 of the shell 2 and is supported with its leg 198 on an end wall 199 of the recess 197 facing the tip of the shoe, only the half of the outer side of the ankle shown from the ski shoe 1. Between the leg 198 and another leg 200 of the U-shaped spring bracket 196, a stop 201 is arranged at a distance 202 from a leg 203 of the U-shaped spring element 172, which runs in the direction of the front flap 5 and with the guide plate 111, for example of the coupling device 116 shown in FIG. 21 is connected to movement. The housing 113 thereof is motionally connected to the front flap 5, as is schematically indicated in a simplified manner. The eccentric lever 117 and the locking pin 118 are also shown. With regard to the functioning of the coupling device, reference is made to the explanations relating thereto in FIG. 21. The front flap 5 of the ski boot 1 is supported on the leg 200 via the guide plate 111. By changing the distance 202 of the stop 201 from the leg 203, when a supporting force 204 of the same size acts on the leg 200, different spring paths result due to different bending lengths of the leg 200. These effect a different damping characteristic, since in the setting shown in full lines, due to the spring characteristic of the leg 200 acting as a bending rod, a larger damping path 205 is achieved compared to a damping path when the stop 201 is set, as shown in broken lines. The damping behavior in the setting shown in full lines is therefore softer and harder in the setting shown in dashed lines. This means that when the supporting force acts on the lower leg an equally high one covers a longer distance until the supporting force is completely diverted into the lower shell part 2. As a result, the transmission of force between the foot of the user and the ski boot 1 or the ski attached to it takes place more slowly in the setting shown in full lines, as is required, for example, when driving in deep snow in order to prevent abrupt power transmission between the foot and the ski shoe or the ski of the ski "dives away" or digs in deep snow, which in many cases leads to the fall of the user of the ski shoe. On hard slopes, on the other hand, it is desirable that the forces required to control the skis are implemented as immediately as possible in order to avoid an undesired slipping when swinging, especially on hard slopes in steep terrain. By changing the distance 202, the spring characteristic of the spring element 172 can therefore be varied within a wide range in a simple manner. Of course, it is also possible for the end wall 199 of the recess 197 to be provided with a cross-sectional shape which is adapted to the cross-sectional shape of the spring clip 196, so that the spring element 172 is prevented from jumping out of the recess 197 when the shoe 1 is in use can. However, this can also be achieved, as indicated schematically, by holders 206 fastened to the lower shell part 2.

In order to adjust the stop 201, it can be motionally connected to a traveling nut 183, which is adjustably mounted on a threaded spindle 207. It is both possible to arrange the stop 201 on its own threaded spindle 207. However, it is also possible to provide only a single threaded spindle 207, which is equipped with counter-rotating threads, so that when the same is rotated, the stop 201 shown, as well as a further stop 201 associated with the inner ankle side of the ski boot 1, which is arranged mirror-symmetrically with respect to the axis of symmetry ¬ orderly traveling nut 183 can be placed apart or together in opposite directions.

Of course, it is also possible with this embodiment support the spring elements 172 by stops firmly connected to the lower shell part 2 in the curved transition area between the legs 19800. Likewise, it is also possible, as shown, to form the stops 201 on their side facing the curved end regions of the spring element 172 with a curvature corresponding to the spring element 172, as a result of which the adjustment path of the stops is optimal can be exploited. The embodiments described above according to FIGS. 18 to 24 form their own independent solution idea according to the invention independently of the other features in the further exemplary embodiments. Likewise, the design of the spring elements 172 can be varied in many ways, and instead of the bow-shaped or U-shaped spring elements shown, C-shaped spring elements or thick springs, torsion springs or the like can also be used. successfully used.
