Description

Technical field

The present invention relates to a ski binding, in particular a touring binding.

State of the art

With regard to their function, ski bindings can be divided into slope bindings that only used for skiing and skiing on ski lifts, and touring bindings that in addition also for walking on skis, especially for ascending with the help of climbing skins attached to the skis can be used. While the former is just a reliable one Fixing the ski boot on the ski in a so-called downhill position to guarantee, the latter must also climb from the departure position can be brought into an ascent position in which the ski boot around a transverse axis is pivotally connected to the ski and in the heel area from the ski can be lifted off to move a joint movement between the ski boot and the Allow skiing.

On touring bindings, completely different, some of them have conflicting requirements. The ascent is as large as possible Freedom of movement between ski boots and skis is desirable to ensure an unhindered To enable walking or climbing. On the other hand, one is possible on departure rigid connection between ski and ski boot on the one hand and between ski boot and On the other hand, the foot / lower leg is desirable for optimal control and guidance of the skis.

In earlier years, the ski boots were mainly made of leather the relatively small stiffness of the shoe leather provides only limited support from Accessible foot / lower leg. On the one hand, this became part of the upgrade the flexibility of the ski boots themselves ensures the necessary mobility of the foot, on the other hand, touring bindings could be used which the Do not limit the flexibility of the upper and sole. For example, in AT 343 522 (Hausleithner) described a touring binding, which for a comfortable Ascending the flexibility of a flexible shoe sole supports it on the one hand pivotable on a first transverse axis in the area of the ski boot tip Ski is articulated and on the other hand in the ball area around a second transverse axis is additionally kinkable.

Since the advent of plastic ski boots, however, ski tourers have also been no longer ready for the much greater hold and the resulting better ski guidance to waive on the descent, which can be reached with plastic ski touring boots are. Today there are practically only plastic ski touring boots with a stiff sole and suitable ski bindings are available on the market for such ski boots. Such Tour binding, which in particular also all safety requirements modern slope bindings are described in WO 96/23559 (Fritschi). she has a shoe rack to which a toe and a heel are attached are, the shoe carrier in the area of the ski boot tip around a horizontal Transverse axis is pivotable with respect to the ski.

Because a swivel movement with a stiff shoe sole around a swivel axis in the area the tip of the ski boot is not that due to the anatomy of the human body corresponds to the given natural course of movement, different Efforts to develop touring bindings have been made Allow more ergonomic movement when climbing. In CH-659 397 (Flückiger) and in WO 87/01296 (Lafranconi) touring bindings are described, where the shoe rack is connected to the ski via a double-joint device is, the shoe carrier in each case at its front end about a first transverse axis is pivotally articulated at the front end of a plate-shaped intermediate piece, which in turn is pivotable at its rear end about a second transverse axis is attached to a ski-fixed base part. In EP 890 379 (Fritschi) one Tour binding described with a double joint device, the shoe rack in the bale area pivotable about a first transverse axis at the rear end of a Intermediate piece is articulated, which in turn at its front end by one second transverse axis is pivotally connected to a ski-fixed base part. All these Touring bindings based on double joints enable ergonomic Sequence of movements when getting on. However, they exhibit an elaborate process Construction on and are therefore comparatively heavy and expensive.

Presentation of the invention

The object of the invention is to provide a touring binding, which one Ergonomic sequence of movements when getting on enables and still one simple construction.

The solution to the problem is defined by the features of claim 1. According to the invention has a ski binding on a ski boot carrier, on which a Hold a ski boot in the area of the toe of trained toe pieces and one designed to hold the ski shoe in the area of the ski shoe heel Heel cheeks are attached, passing through the toe and heel cheeks a longitudinal direction of the ski boot carrier is defined. The ski boot carrier is regarding the ski by a first across the length of the ski and parallel to the top of the ski running pivot axis can be pivoted around. The first pivot axis is in The longitudinal direction of the ski shoe carrier is viewed in one of those for the tip of the ski shoe Set the intended longitudinal position back towards the heel cheek Arranged in a longitudinal position, in a longitudinal area provided for the forefoot, the ski boot carrier being pivotable about the first pivot axis A ski-fixed base part is articulated so that the position of the first pivot axis is fixed with respect to the ski. The ski boot carrier has a front carrier part which the front jaw is attached, and a rear support part to which the heel cheek is attached, the front support part and the rear Carrier part with respect to each other about a second, to the first pivot axis in Substantially parallel pivot axis are pivotable.

The ski-proof base part can be a separate assembly part that is part of the assembly the ski binding firmly on the top of the ski or on one to carry the ski binding provided, firmly attached to the ski binding plate is mounted. The best ski Base part can also be an integral part of the ski or a binding plate be trained. Basically, however, the ski-proof base part is in the assembled state the binding with respect to the ski is immovable and essentially fixed to the Ski connected.

Fixing the position of the first pivot axis means that the Swivel axis during skiing, i.e. both during the ascent as well during the descent, with respect to the ski is fixed. Basically, it is not excluded that the swivel axis e.g. in the course of an adjustment of the bond for different shoe sizes, an adjustment of the binding position (i.e. the Position of the entire binding) with respect to the ski and / or the mounting of the binding can be optionally adjustable on the ski.

In the present context, further information is provided under no other explanation an axis or a swivel axis always a geometric axis or Understood the pivot axis, i.e. an axis in the mathematical sense. A (Geometric) swivel or rotation axis can actually be done by means of a mechanical pivot or rotation axis can be realized. But you can also use a shaft, a hinge, one or more journals, which with corresponding pivot bearings or other suitable swivel or swivel means can be realized. The ski boot carrier can in particular over a swivel joint with only a single (rotation) degree of freedom on the ski Base part to be articulated, this swivel joint being the first swivel axis Are defined.

In a swivel position of the ski boot carrier with the heel jaw lowered defined by the toe piece and the heel piece The longitudinal direction of the ski boot carrier is essentially parallel to the longitudinal direction of the ski. In one order the first pivot axis pivoted around the position such that the heel cheek is lifted away from the top of the ski, however Ski shoe carrier longitudinal direction inclined at an angle with respect to the longitudinal direction of the ski, which is subsequently referred to as the swivel angle of the ski boot carrier with respect to the Longitudinal ski direction is called.

The forefoot area is that in the longitudinal direction between the ball of the foot and referred to the tip of the foot. By the first pivot axis in The longitudinal direction of the ski shoe carrier is viewed in one of those for the tip of the ski shoe Set the intended longitudinal position back towards the heel cheek Longitudinal position is arranged in a longitudinal area provided for the forefoot, a much more ergonomic movement sequence is guaranteed than with Tour bindings of the type in which the ski boot carrier is around a swivel joint is pivotable, in the longitudinal area of the ski boot tip or even in front of it Longitudinal area is arranged.

In contrast to the well-known ski touring bindings, which are ergonomic Enable movement with the help of a double joint in that the first, swivel axis set back from the tip of the ski shoe by another Pivot axis around the ski is pivotable is according to the invention the position of the first pivot axis with respect to the ski essentially fixed immovably. This means that the ski boot carrier has a swivel joint only a single (rotational) degree of freedom is connected to the ski, whereby the first swivel axis is defined by this swivel joint. This will firstly, better and more stable guidance of the ski boot wearer both during the Ascent and descent achieved without the ergonomic Movement is impaired. The one defining the first pivot axis The swivel joint of a ski binding according to the invention can be designed similarly the swivel joint of a known ski touring bindings of the type in which the Ski boot carrier in the area of the ski boot tip around the swivel joint is pivotally connected to the ski.

In that the ski boot carrier has a front carrier part on which the Front jaws is attached, and a rear support part on which the Heel cheek is attached, the front support part and the rear support part with respect to each other about a second, to the first pivot axis substantially parallel pivot axis are pivotable, it ensures that even then when the pivoting movement of the front support part about the first Is blocked around a ski boot held by the binding in the Heel area together with the heel cheek further away from the top of the ski and can be swiveled at the front. This creates the possibility that first pivot axis around which the ski boot carrier with respect to the ski is pivotable, comparatively far from that intended for the tip of the ski boot Longitudinal position in the direction of the heel cheek to be offset.

The ski boot carrier of a ski binding according to the invention is preferably such formed and the first pivot axis is such with respect to the ski boot carrier arranged that the ski boot carrier with respect to the longitudinal direction of the ski boot carrier a front support section arranged in front of the longitudinal position of the first pivot axis and a rear carrier section arranged behind the longitudinal position of this pivot axis has, so that at least in one phase of an ascent step the front one Carrier section swung down towards the top of the ski and the rear Carrier section is pivoted up in the direction away from the top of the ski. Thereby becomes a particularly ergonomic movement when climbing with the Tour binding ensures that the natural movement in barefoot Go comes close.

The first pivot axis is advantageous - in the longitudinal direction of the ski boot carrier considered - by a distance between 3 and 7 cm, preferably by a distance of about 5 cm from the longitudinal position intended for the tip of the ski shoe in the direction arranged set back to the heel cheek. Most ski touring boots with sizes that are typically used for adults the first swivel axis then in one for an ergonomic movement optimal longitudinal area below the forefoot.

According to an advantageous variant of the invention, both the front carrier part are around the first pivot axis can be swiveled around on the ski-fixed base part as well as the rear part Carrier part pivotable about the second pivot axis on the ski-fixed base part articulated, the two pivot axes at different locations on Sic-resistant base part are arranged. In this variant of the invention, in addition to the position first pivot axis also the position of the second pivot axis with respect to the ski fixed. In addition, the front and rear carrier parts are not directly around a single one Swivel axis hinged together. Rather, they are indirect about the ski fixed Base part connected to each other and indirectly pivotable with respect to each other, being both around the first pivot axis and around the second pivot axis are each indirectly pivotable with respect to each other.

According to another advantageous variant of the invention, the rear carrier part is around the first pivot axis pivoted to the ski-fixed base part, and the front Carrier part is pivotable about the second pivot axis on the rear carrier part hinged. The second swivel axis can be positioned in relation to the longitudinal direction of the ski or be arranged behind the first pivot axis. By the rear support part is attached directly to the base of the ski, especially during the ascent a particularly stable guidance of the rear carrier part by means of the binding guaranteed.

According to a further advantageous embodiment of the invention, the front one Carrier part pivotable about the first pivot axis on the ski-fixed base part articulated while and the rear support part around the second pivot axis is pivotally hinged to the front support part. The second can again Swivel axis in relation to the longitudinal direction of the ski in front of or behind the first Be pivot axis arranged. By placing the front support part directly on the ski Base part is articulated, especially during the ascent by means of the binding ensures particularly stable guidance of the front support part.

According to a particularly preferred embodiment of the invention, the ski binding is formed such that the first pivot axis and the second pivot axis coincide. In this case, both the rear support part and the front are Support part can be swiveled around a common swivel axis on the ski-fixed base part articulated, the position of which is fixed with respect to the ski. In addition, the two carrier parts also hinged to one another about the same pivot axis and with respect to one another pivotable to each other. By the first (geometric) pivot axis, around which around the ski boot carrier is hinged to the ski with the second (geometric) Swivel axis coincides, around which the rear support part on the front Carrier part is articulated, the swivel joint mechanism comprising the two swivel axes be constructed particularly simply. For example, just one only (mechanical) pivot axis can be provided, around which on the one hand the front carrier part swivels on the ski-fixed base part and on the other hand the rear part Carrier part are pivotally connected to the front carrier part.

A ski binding according to the invention is preferably further designed such that that the swiveling range of the front carrier part with respect to the ski onto one Maximum value between 30 and 60 degrees, preferably to a maximum value of is limited to about 45 degrees. This means that the front support part is only in one between a first and a second critical angle Swivel range with respect to the ski is pivotable. As the first limit angle (or as the zero position of the swivel angle of the front carrier part with respect to the ski) hereinafter referred to as the angle of a starting position of the ski binding corresponds in which the sole of the ski boot is essentially parallel to the top of the ski is arranged. The front carrier part is from this first critical angle at most up to the second, corresponding to the maximum value of the swivel range Limit angle pivotable with respect to the ski. In the opposite direction it is Swiveling movement of the front support part up to the first, the zero position corresponding limit angle limited. A continuation of the swivel movement over the limit angle is blocked, the blocking either by a appropriate training of the front support part or the toe or can be effected by separate attachment means, which with appropriate Counteracting means work together. It can first stop and Counter-stop means can be provided, which the pivoting movement of the front Carrier part with respect to the ski in the sense of lowering the heel cheek in Limit direction to the top of the ski, and / or second stop and Counter stop means, which the pivoting movement of the front support part regarding the ski in the sense of lifting the heel cheek from the top of the ski limit away.

A ski binding according to the invention preferably further comprises attachment means on front support part and ski-fixed counter-stop means, which are designed and are arranged such that they relate to the pivoting movement of the front carrier part the ski in the sense of lowering the heel cheek towards the top of the ski limit out, the stop means with respect to the front support part and / or the counter-stop means are optionally adjustable with respect to the ski. Through the The adjustability of the attachment means and / or the counter-attachment means becomes Possibility to selectively set the first limit angle. That it becomes the option of optionally pre-setting the swivel position of the front Carrier part created with respect to the ski in a starting position in which the Ski boot sole is arranged essentially parallel to the top of the ski. There one A change in the pivoting position of the front support part usually at the same time Change the height of a front jaw attached or molded to the front jaw Sole hold-down causes, is about the adjustability of the stop and / or Counter-sling a simple adjustment option for adjusting the binding created on different thicknesses of ski boots.

Furthermore, a ski binding according to the invention is preferably designed such that even if the front support part with respect to the ski is in its Swiveling movement is blocked, the ski boot heel of a ski boot with stiffer The sole of the shoe together with the heel cheek further away from the top of the ski can be pivoted up, the ski boot tip still through the Toe is held. For this purpose can be in the top of the front Sole hold-down device a rounded recess can be formed for the Image of the front part of the ski boot that encompasses the toes (sometimes also as Called shoe cap) is provided. The front support part can also be used with a Retention section for the sole tip of the ski boot to which the Pushes the tip of the sole of the ski boot to move the ski boot forward prevent. This sole tip restraint, which also serves as a support can serve for the front sole hold-down, is preferably from an upper Area near the sole retainer downwards, towards the top of the ski in Trained backwards towards the heel cheek so that the ski boot sole at its tip with increasing heel lift relative to the front support part through the restraint towards the heel cheek is pushed back.

According to a further advantageous aspect of the invention, the heel shoe is of this type Slidably arranged in the longitudinal direction of the shoe on the rear carrier part that it against the force of at least one spring is displaceable to, in the case of a Pivoting of the rear carrier part with respect to the front carrier part second pivot axis around an adjustment of the distance between the Toe (or the tip of the sole of a ski boot held by this) and to ensure heel cheeks on a stiff ski boot sole. This will ensures that even if the front support part with respect to the ski is blocked and the ski boot heel of a ski boot with a rigid shoe sole together the heel cheek further pivoted in the direction away from the top of the ski the ski boot continuously between the heel cheek and the toe cheek is held.

A ski binding according to the invention is preferably further designed such that in the first phase of an ascent step, the entire ski boot carrier from one essentially parallel to the top of the ski only about the first pivot axis is pivoted around, while at the same time the rear support part with respect to the front carrier part remains essentially unswiveled, whereupon in a second phase of the ascent step, only the rear carrier part around the second pivot axis is pivoted with respect to the front carrier part, while the front support part is essentially not pivoted with respect to the ski remains.

From the following detailed description and the entirety of the claims there are further advantageous embodiments and combinations of features of the Invention.

Ways of Carrying Out the Invention

The one shown in Fig. 1 in its entirety and in Figures 2-5 in partial views Ski binding according to the invention is a ski touring binding. It has one to hold of a ski shoe in the area of the ski shoe toe 50 which has an elongated ski boot carrier 10 with a for holding the ski boot in Area of the heel shoe 80 is connected. The Ski boot carrier 10 is formed in two parts and comprises a front carrier part 20, the one across the longitudinal direction of the ski (and across the longitudinal direction of the ski boot) and Pivot axis 1 running parallel to the upper side 90 of the ski can be pivoted on one Base part 3 of the binding is articulated by means of screws 8, 9 on the Ski top 90 is attached. The ski boot carrier 10 further includes a rear one Carrier part 40 which is pivotable about the same pivot axis 1 on the front Carrier part 20 (and thus also on the ski-fixed base part 3) is articulated. At the back Support part 40 of the heel jaw 80 is attached and on the front support part 20 Front jaws 50, the front support part 20 itself being an integral part of the Toe is 50.

The rear region of the front carrier part 20 is covered by a spring housing 22 formed in which a compression spring (not shown) is received such that it extends essentially in the longitudinal direction of the front carrier part 20, towards the front slightly rising, located midway between the two long sides of the binding. The Compression spring serves as a release spring for the safety jaw Front jaws 50. The compression spring is supported on the inside of the rear Spring housing rear wall, which also the rear (rear) Longitudinal end of the front support member 20 forms. The compression spring presses from the front on a pressure piece, which with two pin-shaped projections 24, 26 (hereinafter as Push pins 26, 26) is provided through openings in the front wall of the spring housing 22 protrude forward out of the spring housing 22.

Between the two pressure pins is on the front of the spring housing Elongated support member 28 is formed, which supports the front sole holder 52. The The upper side of the support part 28 is viewed in the form of an arc in the longitudinal direction of the carrier trained that they are in a starting position of the ski binding as shown in the figures 1 to 3 and in which the ski boot sole is essentially horizontal (i.e. parallel to the top of the ski 90) from the spring housing 22 to at the front horizontally (i.e. parallel to the ski boot sole), then increasingly rising and finally vertical (i.e. perpendicular to the ski boot sole). The Top of the support member 28 for the sole holder also serves as a support surface for the sole of the ski in the area of the toe, the foremost being at right angles to Section of the ski boot running as a retention part for the toe of the sole Ski boots are used, to which the sole tip in the foremost possible position of the Ski boots knock in the binding. The arcuate shape of the as a support surface for the sole tip serving top of the support member 28 also causes - if the front carrier part 20 is blocked with respect to the pivot axis 1 and the shoe heel of a ski boot with a stiff sole - the Ski boot sole at its tip with increasing heel lift the front support member 20 from the front sole holder 52 and the restraint is pushed back towards the heel cheek 80.

The front sole holder 52 is laterally about a central pivot axis 54 can be swung out on the foremost, projecting essentially vertically upwards Batch of the support member 28 stored. It has two protruding downwards and backwards lateral support arms 56 which extend rearward on the front faces support the push pins 24. This ensures that when the Ski shoe tip exerts excessive lateral forces on the front sole holder 52, this swings out laterally against the spring force of the release spring and thereby releases the ski boot.

The upper part of the sole holder 52, which essentially extends from the support part 28 extends parallel to the sole of the ski boot to hold down the Ski boot sole. In the top of this hold-down section of the front sole holder 52 is a rounded recess 58 which is designed to receive the Front part of the ski boot encompassing the toes (sometimes also as a shoe cap designated) is provided. This recess 58 ensures that the Ski boot tip of a ski boot with a stiff sole even through the Front jaw 50 is held when the front support member 20 with respect to the Swivel axis 1 is blocked and the ski boot heel together with the heel cheek 80 is pivoted further up in the direction of the top 90 of the ski.

Approximately in the longitudinal center of the spring housing 22 are two on the top rib-shaped flanges 30, 31 formed with a continuous transverse bore are provided, in which a mechanical joint axis 2 is received in such a way that the front support part 20 is pivotable about this hinge axis 2. This mechanical hinge axis 2 defines the geometric pivot axis 1 about which around the ski boot carrier 10 is hinged to the ski-fixed base part 3.

The hinge axis 2 is supported by two laterally projecting support walls 4, 5 of the ski base part 3 of the binding worn, for this purpose in the two Support walls 4, 5 each have a transverse bore in which the axis 2 is included. The two support walls 4, 5 essentially extend in FIG Ski longitudinal direction and protrude at right angles to the top 90 of the ski. They are below via a plate-shaped web section 6 running parallel to the top of the ski connected to each other, which rests directly on the ski top 90 and by means of Screws 8, 9 is firmly fixed on the same. In a cross section across The longitudinal direction of the ski has this from the plate-shaped web section 6 and the two Support walls 4, 5 formed ski-fixed base part 3 an essentially U-shaped Shape.

The entire underside of the front carrier part 20 is in a longitudinal area in front of the Swivel axis 1 formed such that it rises to the front. The slope is dimensioned such that the front carrier part 20 of one in FIGS shown starting position of the ski binding in which the ski boot sole in Is arranged substantially parallel to the top of the ski 90 to a maximum Swivel angle of approximately 45 degrees in the sense of swiveling the Heel cheek 80 away from ski top 90 (i.e. in the sense of lowering the front sole holder 52 to the top of the ski) around the pivot axis can be pivoted until the underside of the front section of the front Carrier part 20 on the ski top 90 or on the plate-shaped web portion 6 of the ski fixed base part 3 and thereby pivots the front Carrier part 20 blocked around the pivot axis 1. In this swivel position it is front support member 20 shown in Figures 4 and 5.

In a longitudinal area behind the pivot axis 1 is the underside of the front Carrier part 20 is formed sinking to the rear in such a way that it is shown in the figures 1 to 3 shown starting position of the ski binding with parallel to the top of the ski arranged ski boot sole at the rear on the ski top 90 or on the plate-shaped web portion 6 of the ski-fixed base part 3 rests. This will make the Pivotal movement of the front support member 20 in the sense of lowering the Heel cheek 80 towards ski top 90 (i.e. in the sense of lifting the front sole holder 52 from the ski top 90 away) limited. So overall the front bracket 20 within a pivoting range of approximately 45 degrees between the pivot position shown in FIGS. 1 to 3 and that in FIGS. 4 and 5 shown pivot position about the pivot axis 1 pivotable.

On the same axis 2 carried by the ski-fixed base part 3, on which the front part 20 of the ski boot carrier 10 is articulated, its rear part 40 is also hinged. For the purpose of articulation on the hinge axis 2 are on the front of each Side of the rear support part 40 each two leaf or rib-shaped flange parts 41, 42, 43, 44 are formed, which protrude from the rear carrier part 40 and forward each include one of the two support walls 4, 5 of the ski-fixed base part 3 laterally. In all four flange portions 41, 42, 43, 44 of the rear support part 40 are aligned holes are formed in which the mechanical Hinge axis 2 is added to the rear support member 40 by the same Geometric pivot axis 1 pivotable on the front support member 20 (and thus also to be attached to the ski-fixed base part 3), around which the front part too Carrier part 20 is pivotally articulated on the ski-fixed base part 3.

Immediately behind the pivot axis 1 is approximately in the bale area in the Binding inserted ski boot on the top of the rear support part 40 a laterally swiveling pivot plate 46 is arranged, the top of which up little protrudes from the top of the remaining areas of the rear support member 40 and which serves as the actual shoe pad in the front area of the ski binding. This Swivel plate 46 supports the lateral pivoting out of the front sole holder 52 to 50 in the event of a safety release of the toe piece To release the ski boot tip.

In its rear area, the rear carrier part 40 is an elongated hollow profile 48 formed, which is in the initial position shown in Figures 1 to 3 Ski binding extends essentially parallel to the longitudinal direction of the ski. At this Hollow profile 48 is the heel jaw 80 with respect to the rear support part 40 in Carrier longitudinally arranged displaceably. Via an inside the hollow profile 80 arranged tension spring (not shown) is the heel shoe 80 with a locking part (not shown) connected, which is also inside the hollow profile 48, in front of the Longitudinal position of the heel shoe 80 is arranged and in the longitudinal direction of the carrier with respect the rear support part 40 adjustable and in a variety of longitudinal positions is optionally lockable. In the course of setting the ski binding for a certain The length of the ski boot becomes the desired longitudinal position of the heel shoe 80 the rear support part 40 by appropriate adjustment and locking of the Locking part fixed with respect to the rear support member 40. After locking the Locking part of the heel jaw 80 is only against the force of the tension spring along the hollow profile 48 of the rear support member 40 slidable to the rear In the event of pivoting of the rear support part 40 with respect to the front Carrier part 20 around the pivot axis 1 around an adjustment of the distance between the toe 50 (or the tip of the sole of a ski boot held by this) and the heel cheek 80 to ensure a stiff ski boot sole.

The heel shoe 80 has an operable by means of an actuating lever 82 Automatic heel unit 84 on which a rear sole holder 86 for holding the Ski boot sole is attached in the heel area. Furthermore, that in FIGS to 5 shown ski binding one behind the heel cheek on the top of the ski attached locking device 92, by means of which to the rear over the Heel jaws 80 protruding end piece 49 of the hollow profile 48 of the rear Carrier part 40 can optionally be locked and unlocked. When unlocked End piece 49 is the ski binding in its ascent position, in which the Ski boot carrier 10 is pivotable about the pivot axis 1 around the skier to allow ascent with the bond. In the down position of the binding is the end piece 49 locked so that the entire ski boot carrier 10 is fixed and is pivotally connected to the ski. Overall, the automatic heel unit is 84 and the locking device 92 is configured similarly to the corresponding binding components the binding described in WO 96/23559 (Fritschi).

In the foremost area of the ski binding there is also an at least partially made of one Rubber-elastic material made cover element 15 arranged. This covers the foremost area of the ski binding between the ski-fixed base part 3, the Front jaws 50 and the top of the ski 90 in a sealing function from the Prevent snow from entering this binding area.

In order to ascend with the ski binding shown in FIGS. 1 to 5, it becomes first brought into its ascent position by means of the locking device 92 the end piece 49 of the rear carrier part 40 is unlocked. The ski binding is located then in their initial position shown in Figures 1 to 3, in which the Ski boot carrier 10 and the sole of a ski boot used in the ski binding are arranged substantially horizontally (i.e. parallel to the upper side 90 of the ski).

Starting from this starting position, the skier then lifts in a first Phase of an ascent step on the shoe heel. In the first phase of Ascent step, the entire ski boot carrier 10 together with the front and the Heel jaws 50, 80 are pivoted about pivot axis 1. The in Skischuhträgerlängsrichtung arranged in front of the longitudinal position of the pivot axis 1 Batch of the ski boot carrier 10 towards the top 90 of the ski downwards pivoted and arranged behind the longitudinal position of the pivot axis 1 Carrier section swung up in the direction away from the top 90 of the ski. Due to the stiff ski boot sole remains the rear in the first phase of the ascent step Carrier part 40 is essentially not pivoted with respect to the front carrier part 20.

If the skier takes a comparatively long ascent and the ski boot with respect to the ski pivoted through a larger angle than the maximum Swivel angle of approximately 45 degrees around which the front support part 20 by Pivot axis 1 is pivotable with respect to the ski, is the first phase of the Ascent step with reaching the binding position shown in Fig. 4 finished in which the underside of the front portion of the front support member 20 the ski top 90 or to the plate-shaped web portion 6 of the ski-fixed base part 3 abuts. From now on, in the course of a continuation of the swiveling movement of the Ski boots in the same direction in a second phase of the ascent step only the rear support part 40 around the pivot axis 1 with respect to the front support member 20 pivoted while in this second phase of Ascent step of the front support part 20 with respect to the ski essentially remains undeflected (i.e. blocked). In the second phase of the ascent step the sole tip (and thus the entire ski boot) through the front sole holder 52 and the arcuate shape of the top of the support member 28 of the front Sole holder 52 pushed back from the front sole holder 52, and the toe cap (i.e. the foremost part of the ski boot above the Shoe sole) is received in the recess 58, which is in the top of the Hold-down portion of the front sole holder 52 is formed. At the same time the heel jaws 80 against the force of the tension spring along the hollow profile 48 of the rear carrier part 40 moved backwards. This will make the longitudinal position of the Heel cheek 80 with respect to the rear support member 40 at the distance between the Sole tip and the heel of the ski boot adjusted, making an adjustment this longitudinal position on the one hand due to the away from the front sole holder 52 rear shifting of the ski boot sole and on the other hand due to the Pivoting of the rear support part 40 with respect to the front support part 20 is required.

The second phase of the ascent step can go as far as one shown in FIG Binding position are continued, in which the rear support part 40 by approximately 90 degrees away from the ski. If desired, the second phase of the ascent step continued and the ski boot inserted in the binding together with the rear support part 40 and the heel cheek 80 even further in the be pivoted in the same direction away from the starting position.

As soon as the skier pulls the ski in the course of an ascent step begins, the ski boot carrier 10 is swung out with respect to the ski Position pivoted back towards the starting position until the in the Figures 1 to 3 shown starting position is reached. Doing the above described movements of the first and possibly the second phase of a Ascent step in reverse order and movement or swivel direction executed.

Usually with ski touring bindings, this is hardly the case long strides that the shoe related more than about 45 degrees the ski has to be swiveled. In this case, the second described above Ascent phase not completed. The pivoting movement of the binding is then canceled during the first phase of the ascent step and returned in the opposite direction to the starting position of the binding. In this Fall remains the rear support member 40 with respect to the front support member 20 during the whole ascent step is not pivoted, and the heel jaw 80 remains with respect to the rear carrier part 40 substantially not shifted.

With a ski binding according to another embodiment, not shown in the figures the invention is at the back of a stop on the underside of the front support member attached, which in the starting position of the ski binding with parallel to Ski shoe sole arranged on the ski top rests on the ski top and thereby the Pivotal movement of the front support part limited. The stop is by means of a Adjusting screw with respect to the front support part optionally adjustable such that the Swivel angle of the front carrier part, which with the starting position of the binding on the top of the ski corresponds to the stop can. Since the swivel angle also changes the height of the front sole holder, can adjust the binding for different ski boot sole thicknesses in this way become.
