Description

The invention relates to a ski with a connecting device for connecting a front and rear shoe body having ski binding with the ski, as indicated in claim 1.

From the prior art it is known to couple the two jaw members of a ski binding, which comprises a toe and a heel jaw distanced therefrom, with the ski body with the interposition of a binding support plate or a so-called binding plate. In this case, essentially four basic principles with regard to the coupling of the binding support plate to the ski are known. In particular, the load or force-transmitting coupling between the binding support plate and the ski body can be carried out starting from the central portion of the binding support plate or starting from the front and / or rear end of the binding support plate, as for example in the DE 21 34 810 A1 and the DE 21 35 450 A1 is disclosed.

In particular, it is known to support the opposite, distal ends or end portions of the binding support plate load-bearing on the ski and thereby provide coupling mechanisms by which the through or bending of the body is as little as possible affected to achieve a harmonic bending line and the ski below to stiffen the binding support plate as little as possible despite attachment of the ski binding or the binding support plate. For this purpose, combinations of joint connections or joint and guide connections are provided, which are formed on the opposite end portions of the binding support plate, as for example the publications US 5,129,668 A . DE 39 32 438 A1 . EP 1 051 225 A1 , or the CH 681205 A5 can be seen. Depending on the stability or flexural rigidity of the binding support plate, elastomeric inserts can also be provided in the sections between the distal support or joint connections relative to the ski, which are arranged between the binding support plate and the shock absorber side and thereby fulfill a damping function or an elastic deflection Keep the highly stressed binding support plate behind.

In addition to the aforementioned binding support plates with front side arranged Schikopplungsmechanismen, such as joints and linear guides, it is also known to connect a relatively rigid binding support plate in its central or central portion hinged to the ski and at least one distal end, in particular the rear support plate end over a Coupling rod to connect with the ski, so that a change in the inclination of the footprint of the support body relative to the ski body is effected as a function of the elastic deflection or bending of the ski body, as the EP 0 780 142 B1 can be seen. According to another embodiment, it has been proposed to rigidly couple the rear half of the binding support plate to the ski and to carry out the front half of the binding support plate as a free-standing bending support, as disclosed in FIGS. 7, 8 of said publication. However, the achievable with these constructions performance is only partially satisfactory.

According to the EP 0 780 143 B1 is provided to connect the front end of the binding plate firmly and height stable with the ski and to store the rear end of the binding support plate with respect to the Schioberseite height adjustable. In the longitudinal middle section of the binding support plate, a rigid support element is provided, which ensures a fixed minimum height between the binding support plate and the Schioberseite. With this construction, the rigidity of the ski is to be influenced under the action of a pressure force exerted by the user.

In the WO 2008/032349 A1 a bonding support plate is specified, which ensures a more even or far-reaching pressure distribution of the ski body relative to the ground. In this case, a rigid as possible binding support plate is provided, which is preferably formed of metal or of a carbon fiber composite material (CFRP). This highly rigid binding support plate is connected in its middle section either via a hinge connection or via a rigid connection with the ski body. At the opposite ends of the support plate each extension arms are provided, which extend in the direction of the ski tip or in the direction of the ski end and in each case via a joint connection and a combined rotational and translational connection, the binding support plate with the ski. By extending to the front and rear extension arms a wider force or pressure distribution is to be achieved starting from the binding support plate on the ski body. The disadvantage is that a highly rigid support plate made of metal or CFRP is required in order to withstand the position occurring during use of the ski force effects sufficiently stable position. Particularly in the case of elastic bends or bends of the binding support plate supported centrally or centrally on the bumper, there are significant performance losses with regard to controllability or with regard to the most direct or instantaneous maneuverability of the breech body.

The present invention has for its object to provide a ski with a connection device for the ski binding, wherein the ski body as possible unrestrained or free, elastic deformation should be made possible below the connecting device, and wherein the performance in terms of maneuverability or instantaneous initiation of Control forces from the user on the ski body should be as high as possible.

This object of the invention is achieved by a ski with a connecting device according to claim 1. An advantage of the design according to the invention is that thereby a ski is created with the highest possible performance, especially in terms of maneuverability, which also can meet high economic and aesthetic demands. Among other things, the plastic-formed or shaped, free-standing bending beam is integrated as harmoniously as possible in the overall structure in terms of its visual appearance. In addition, the corresponding connecting device is relatively inexpensive to produce, after a series production is possible in conjunction with injection-molded plastic parts, which are relatively inexpensive to produce compared to metallic components or CFRP parts that would require elaborate processing or manufacturing processes. In particular, the stated construction is comparatively rational to manufacture and attractive in terms of cost and visual appearance to a wide circle of potential users. A significant advantage of the embodiment according to the invention lies in the fact that the ski is stiffened as little as possible by the centrally or centrally mounted support body for the jaws of the ski binding, in particular a relatively free, harmonic bending characteristic of the ski body is ensured against the connecting device mounted thereon. This relatively free or unimpeded elastic deflection or bending of the ski body is not impaired by the specified coupling device.

A particular advantage of this coupling device is that it significantly increases the torsional rigidity of the cantilevered bending beam of the connecting device. In particular, the relatively high torsional rigidity of the ski body in the area of the bond mounting zone is utilized in order to significantly increase the torsional rigidity of the free-standing plastic bending beam. As a result, the control or torsional forces introduced by the user on the free-standing bending beam are reliably absorbed without any disadvantageous distortion of the bending beam about its longitudinal axis. Consequently, the most direct and delay-free and exact controllability of the ski is ensured. While the coupling device so largely prevents twisting of the plate-like support body and thereby raises the torsional stiffness, relative movements between the free-standing bending beam and the ski body in the vertical direction to Schioberseite and also allowed in Schilängsrichtung. An advantage of this coupling device is also that a precise and long-term wear-free, mechanical coupling is ensured by the arrangement of one of the joint connections of the connecting arm directly on a guide carriage. In addition, such a guide carriage can withstand relatively high torsional or torsional forces without long-term wear and tolerances occur.

A particular advantage of the design according to the invention lies in the fact that the bending beam formed from plastic is limited in relation to lifting or distancing movements relative to the top of the ski. In particular, the free-standing bending beam of the connecting device is limited by the limiting element with respect to distancing tendencies from the Schioberseite. Thus, while the bending beam and the ski body can approach each other in the course of the usual use or bending of the ski, a maximum distance distance between said components is limited. In addition, the free-standing bending beam can thereby reliably absorb the relatively high distortion forces against the bending beam occurring when the user backwards or forwards falls, without conditions or relative positions occurring which would impair the safety trigger values of a safety binding. Accordingly, in addition to the requirements for high performance, high cost-effectiveness and high aesthetic demands or design options, the specified device also meets high safety requirements in combination with mounted or supported hinges.

Also advantageous are the measures according to claim 2, since thereby the strength or bending stiffness of the free-carrying bending beam of the connecting device can be further increased, while nevertheless the most economical production possible. In particular, this can be used to build an automated and thus relatively cost-effective series production, the corresponding construction meeting both high economic and performance-oriented requirements.

An advantageous embodiment is also specified in claim 3. In particular, this provides a multiple, technical functionality of the bearing body, whereby the number of parts is reduced and the total cost of providing a corresponding ski can be reduced. In addition, the bearing body, which is substantially C-shaped in cross-section, thereby forms a type of cladding or spoiler element for the front longitudinal end of the support body, which cladding or spoiler element can cover or clad the mechanically or kinematically relevant components of the coupling device. As a result, aesthetic demands, but also requirements in terms of functional reliability and robustness of the coupling device in a simple manner taken into account.

Also advantageous are the measures according to claim 4, as a robust or long-term planned functioning coupling device is created, which can easily withstand high force, especially strong torsional or torsional forces in the course of the use of the ski.

Also advantageous are the measures according to claim 5, characterized in that the free-standing bending beam of the support body is elastically yielding supported and thus the bending stiffness can be selectively influenced or increased to the desired extent. Nevertheless, it is possible that the ski body can perform the corresponding deflection or elastic deformation in the area below the binding support plate as freely as possible, so that a harmonious or uniformly extending bending characteristic is achieved, which favors the achievable with the ski performance.

But there are also the measures according to claim 6 of advantage, as this is an almost punctual support or support surface is created, which on the one hand supports the cantilevered bending beam relative to the Schioberseite and thus counteracts a decrease thereof. On the other hand, as far as possible unhindered elastic deformation of the ski body is favored or maintained in the section underneath the free-standing bending support.

Also advantageous are the measures according to claim 7, since thereby the achievable with this ski performance is relatively high. In particular, performance-oriented aspects are thereby taken better into account after the ski body can build up a relatively uniform or harmonious bending line. As a result, optimum grip against the ground can be built up and a well-controlled cornering behavior can be achieved. This is achieved, inter alia, by the rear end of the supporting body which is held free in relation to the ski in the longitudinal direction of the ski.

Furthermore, the measures according to claim 8 are advantageous because a highly stable, yet lightweight connection of the rear end portion of the support body is created with the ski. Nevertheless, a possible tension-free, in the longitudinal direction free-sliding coupling between said elements is guaranteed.

In the measures according to claim 9 it is advantageous that the supporting body or the free-standing bending beam of the connecting device fulfills a multiple functionality, so that additional components are unnecessary and thus the production costs can be kept as low as possible. In addition, thereby the overall weight of the corresponding embodiment can be kept relatively low. Nevertheless, a ski binding in a simple manner to the respective shoe sizes can be customized by the appropriate design. In addition, a free-sliding holder of at least one jaw body of the ski binding against the support body can be efficiently implemented.

Of advantage is also a dimensioning according to claim 10, as a certain damping or Abfederungsfunktion is created by the connecting device or its supporting body. In particular, when driving on the ski acting blows transmitted in a damped form to the user, whereby the user comfort can be increased.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. Furthermore, may also represent individual features or combinations of features from the illustrated and described different embodiments for themselves, inventive or inventive solutions.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all sub-areas begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

In the Fig. 1, 2 An exemplary embodiment of a ski 1 according to the invention is illustrated with a connecting device 3 arranged on its upper side 2 for a ski binding (not shown). Such a ski binding comprises a front jaw body, not shown, for releasable coupling with the toe portion of a sports shoe and a distance therefrom, the rear shoe body for releasably releasable coupling with the heel portion of the sports shoe of a user. In particular, any known from the prior art ski binding can be attached to the connecting device 3, in particular form-fitting pushed and fixed to the respective desired relative position. As a result, the individual shoe sizes of the respective user can be met. This ski binding preferably fulfills the function of a so-called safety ski binding which releases the sports shoe of the user when predefined trigger values or force threshold values occur.

The connecting device 3 on the upper side 2 of the ski 1 in this case comprises a substantially plate-like or rail-like support body 4 for the two jaw members of the ski binding. In particular, the support body 4 is formed in its front or Schispitzenseitigen end portion 5 for holding the front jaw body and in its rear end portion 6 for holding the rear jaw body. The plate-like support body 4 of the connecting device 3 in this case has a length between 40 to 70 cm, preferably of about 55 cm. In contrast, the length of the ski 1 is a multiple of the length of the support body 4, typically between 140 cm to 190 cm.

The connecting device 3 between the ski binding and the ski 1 is designed as a so-called central or middle-fixed binding plate. This means that the support body 4 of the connecting device 3 in its longitudinal center section 7 has a fastening zone 8 for rigid connection with the ski 1. The fastening zone 8 has a longitudinal extent of up to 10 cm in relation to the longitudinal direction of the ski. In the illustrated embodiment, the support body 4 is screwed rigidly or fixedly to the ski 1 via a plurality of fastening means 9, in particular screws. A paired arrangement of at least two screws, beispielsgemäß of four screws, is expedient. Typically, this attachment zone 8 is located approximately in the longitudinal center of the support body 4 and the connecting device 3, as this especially from Fig. 2 is apparent. In this attachment zone 8 in the region of the longitudinal middle section 7 of the support body 4, a coupling which is as rigid as possible or unyielding in relation to all spatial directions, in particular a screw connection, is constructed between the support body 4 and the ski 1.

At least the front end portion 5 of the support body 4 forms with respect to the central attachment zone 8 of the supporting body 4 a free-standing bending beam 10, as best of Fig. 3b is apparent. In particular, the support body 4, starting from its central attachment zone 8, in which it rests directly on the upper side 2 of the ski 1, at least in the direction of the front end portion 5 is cantilevered, that is spaced from the top 2 of the ski 1. According to the illustrated embodiment, only the front end portion 5 of the support body 4 is designed free-standing or static self-supporting and thus does not rely on at least in its foremost end portion on the top 2 of the ski 1 from. The support body 4 is therefore at least in its front part, in particular at least in the front third of its longitudinal extent, a cantilevered bending beam 10. The one-sided clamping or mounting is based on the central or longitudinally central attachment zone 8. The front, free-standing end portion 5 of the support body 4 may be between 20% to 50%, preferably between 30% to 40% of the length of the support body 4.

Consequently, the underside 11 of the support body 4 is positioned at least in the front end portion 5 of the support body 4 in a vertical distance 12 to the top 2 of the ski 1. By this distance 12 results in a gap-like space 13 between the bottom 11 of the support body 4 and the top 2 of the ski 1. This space 13 is preferably through formed on the Schioberseite, trough-like surface recess 14 formed. This means that a thickness 15 of the ski 1 in its longitudinal section with the greatest distance 12 to the underside of the supporting body 4 is comparatively smaller than a thickness 16 of the ski 1 within the fastening zone 8 or in the vicinity of the fastening means 9 vertical height of the free space 13, in particular the distance 12, be kept sufficiently large to ensure a sufficient relative movement between the free-standing bending beam 10 and the Schioberseite. In addition, the supporting body 4 can thus remain approximately constant over long sections with respect to its thickness progression in the longitudinal direction and can thus be made sufficiently stable. Of course, it is also possible to taper the support body 4 at least in the direction of its front longitudinal end 19 toward stepwise or continuously, in order to achieve a sufficient vertical distance 12 in the region of the front longitudinal end 19, which is a relative adjustment, in particular a load-related approach between allows the front end portion 5 and the Schioberseite. Such an approach takes place in the course of the load or pressurization of the support body 4 during use of ski 1. These typical loads result in an elastic deformation of the support body 4, in particular of its protruding from the central attachment zone 8, front and / or rear end portion 5, 6.

Preferably, at least the front end portion 5 of the support body 4 is executed at least in sections as a free-standing bending beam 10 with respect to the top 2 of the ski 1. Alternatively or in combination, however, it is also possible to carry out the rear end portion 6 of the supporting body 4 as a free-standing bending beam, that is, at least within sub-sections with respect to the top 2 of the ski 1 to distance, so that a gap-like space, in particular a vertical range of motion between the rear end portion 6 and the Schioberseite is given.

Due to the distance 12, a reduction in the distance 12 is possible in the forces or loads occurring in use in the vertical direction on the upper side 17 of the front end portion 5 in the use. In particular, the front end section 5 embodied as a free-standing bending support 10 can resiliently spring in the direction of the ski side and thereby cushion or dampen sudden loads, such as may occur during use of the ski 1.

This resilient and resilient, cantilever executed bending beam 10 of the support body 4 is formed from plastic, in particular molded from plastic. Thereby, a maximum travel of up to 10 mm, preferably of about 5 mm between the bottom 11 and the Schioberseite possible without the elasticity of the bending beam 10 is permanently impaired or the yield strength of the plastic is exceeded. According to an advantageous embodiment, it is provided that the bending beam 10 or the major part of the rail or plate-like support body 4 is formed of glass fiber reinforced, molded plastic. According to an advantageous embodiment, it is provided to form the support body 4, in particular the at least one free-standing bending beam 10 of the connecting device 3 made of glass fiber reinforced polyamide, in particular PA6 with a glass fiber content of up to 45%. It is expedient to use as plastic for the support body 4, in particular for the at least one free-standing bending beam 10, molded PA6-GF30 or PA6-GF40 in order to achieve a favorable strength but also elasticity of the supporting body 4 in the region of the free-standing bending beam 10. It is expedient if the plastic used has an E-modulus between 6,000 and 14,000 MPa, preferably about 10,000 MPa.

The elasticity or flexural stiffness of the cantilevered bending beam 10 is suitably dimensioned such that at a force between 200 N and 350 N on the front longitudinal end 19 of the support body 4 and on the schispitzenseitige end of the front end portion 5, wherein the force perpendicular to the top 17 is aligned, a relative position between 1 mm and 3 mm, in particular of about 2 mm, occurs in the direction of the Schioberseite. The elasticity or flexural rigidity of the cantilevered bending beam 10 of the support body 4 may also be dimensioned according to a favorable design such that at a force application according to the above manner between 500 N and 800 N, a relative position between 3 mm and 5 mm, in particular of about 4 mm, towards the Schioberseite occurs. The corresponding elasticity or flexural strength values can be provided by the support body 4 or by its free-standing bending support 10, preferably including the support effect of an elastically yielding support body 36 explained below.

The connecting device 3 further comprises at least one mechanical coupling device 18 at at least one longitudinal end, in particular at the front longitudinal end 19 of the support body 4. This mechanical coupling device 18 is designed such that a load-related change of the distance 12 between the cantilevered bending beam 10 and the Schioberseite allows or is admitted, however, a twisting of the free-carrying bending beam 10 about its longitudinal axis or about the longitudinal axis Schilängsachse is prevented as possible. In particular, the coupling device 18 serves to inhibit or prevent elastic twisting of the cantilevered bending beam 10 or of the front end section 5 of the supporting body 4 as a result of acting torsional forces. Such a coupling device 18 is preferably provided on each freely projecting end of the support body 4. This means that, even if the rear end portion 6 of the support body 4 is made free-running, and the rear longitudinal end 20 is associated with such a coupling device. In the illustrated embodiment, the rear end portion 6 of the support body 4 is located with its bottom 11 substantially gap-free on the Schioberseite, so that no free-standing end portion is present, as is made Fig. 3a is apparent. Accordingly, according to the embodiment shown in the rear end portion 6 of the supporting body 4, no mechanical coupling device is provided relative to the ski body.

In the Fig. 4, 5 is the at least one longitudinal end 19, 20 of the support body 4 formed, mechanical coupling device 18 is shown enlarged.

This coupling device 18 comprises a longitudinally section, in particular with respect to a vertical section running parallel to the ski longitudinal direction, a substantially C-shaped bearing body 21. A lower leg 22 of this substantially C-shaped bearing body 21 forms a bearing point 23 for a mechanical connecting arm 24th to the support body 4, in particular to the front longitudinal end 19 of. In particular, the coupling device 18 comprises a connecting arm 24, which has in its first end portion a first articulated connection 25 with respect to the cantilever bending beam 10, and in its second end portion has a second articulated connection 26 with respect to the ski 1. The two articulated joints 25, 26 form transverse to the ski longitudinal direction and substantially parallel to the tread 27 of the Schi 1 - Fig. 3a, b - Running pivot axes 28, 29 off. Preferably, these pivot axes 28, 29 are formed by bolt connections. Alternatively, it is also possible, at least one hinge connection 25, 26 or at least one pivot axis 28, 29 form by a so-called material or film hinge, in particular a material taper in the transition section between connecting arm 24 and bearing body 21 and between connecting arm 24 and bending beam 10 provide.

The bearing body 21 is rigidly connected to the ski 1, in particular fixed immovably on at least one screw-like fastener 30 on the Schioberseite. The leg 22 of the C-shaped bearing body 21 forms a subcomponent of the second articulated joint 26, as best of all Fig. 5 is apparent. The first or upper joint connection 25 of the connecting arm 24 is preferably formed on a guide carriage 31, which is slidingly or translatorily adjustable in the longitudinal direction of the ski. Preferably, this guide carriage 31 is carried out on the support body 4, in particular on its front longitudinal end 19, as shown in the Fig. 4, 5 is apparent. It is useful if this guide carriage 31 has a sliding plate 32 which is slidably guided in a guide groove 33 on the cantilever bending beam 10 with respect to the Schilängsrichtung. This slide plate 32 of the guide carriage 31 is coupled via the first articulated connection 25 with the connecting arm 24 or articulated. By this mechanical coupling comprising the connecting arm 24 with the two articulated joints 25, 26 and the guide slide 31 slidable in Schilängsrichtung Distanzungs- and approaching movements between the bending beam 10 and the Schioberseite allowed twisting or lateral deviating movements of the cantilever beam 10, however, inhibited or inhibited. It is expedient here to guide the sliding plate 32 in the guide groove 33 in such a way that the sliding plate 32 is mounted free of play or approximately free of play transversely to the longitudinal axis of the support body 4.

Instead of the assignment of the guide carriage 31 to the support body 4 and the bending beam 10, it is also possible to assign a corresponding, translational longitudinal compensation to the bearing body 21, in particular to guide the guide carriage on the bearing body 21 and provide a purely rotational articulated connection 25 directly on the bending beam 10.

It is particularly expedient to form at least one limiting element 34, which is used to suppress, limit or inhibit stress-related lift-off tendencies or lift-off movements of the bending beam 10 relative to the ski 1 is formed. In particular, at least one limiting element 34 is provided, which causes a limitation of the maximum distance 12 between the underside 11 of the bending beam 10 and the Schioberseite. In functional terms, this limiting element 34 avoids a stress-related elastic bending or distancing of the front longitudinal end 19 over a substantially rectilinear extent of the front end portion 5 of time. Thus, a load-related, arcuate bending or raising of the cantilevered beam 10 is suppressed, limited or inhibited to a sufficient extent. Excessive stress or fracture-endangering loads of the free-standing bending beam 10 are thereby avoided. In addition, thereby relative states can be suppressed or avoided, which would unduly change the security function of a security bond arranged thereon. This limiting element 34 is of importance, inter alia, in connection with the tearing forces on the front, cantilevered bending carrier 10 which occur in the event of backward falls of the user.

It is particularly expedient if the substantially longitudinal C-shaped bearing body 21 with its upper leg 35 forms the at least one delimiting element 34 with respect to a vertical longitudinal section running parallel to the longitudinal direction of the ski. In particular, the leg 35 is a kind of stopper element which inhibits, inhibits, or limits a lift-off movement of the bending beam 10 relative to the skiver side, as best shown in FIG Fig. 5 can be seen.

According to an expedient embodiment, it is provided to support the elastically yielding, cantilevered bending beam 10 resiliently yielding. In this case, at least one elastically resilient supporting body 36 is provided between the top 2 of the ski 1 and the bottom 11 of the bending beam 10. This elastically yielding support body 36 supports the free-standing bending beam 10 with respect to the ski side elastically yielding. According to an advantageous embodiment, the support body 36 is formed by an elastomeric foam element 37. This supporting body 36 exerts on the underside 11 of the bending beam 10, a support or counterforce, which opposes increased load resistance reduction of the distance 12.

According to an advantageous embodiment, it is provided that the elastically yielding supporting body 36 has a bearing length 38 of less than 5 cm relative to the upper side 2 of the ski 1 and / or a longitudinal support length 39 of less than 5 cm relative to the bending beam 10 has. How best Fig. 4 it can be seen, it may be expedient to provide a pair of elastically resilient supporting bodies 36.

How best from a synopsis of Fig. 2 and 4 it can be seen, the front and / or rear end portion 5, 6 of the supporting body 4 may have a substantially hat rail or C-shaped cross-sectional contour. As a result, the front and / or the rear end section 5, 6 of the support body 4 forms a longitudinal guide 40, 41 for the front and / or rear jaw body of a ski binding. In particular, this makes it possible to use the support body 4 for direct reception or for load-bearing retention of the back body of a ski binding. Via these longitudinal guides 40, 41 is then in a simple manner an individual adjustment of the distance between the jaw members, that is an adaptation to the respective shoe size, and / or allows an individual change of the shoe foot center with respect to the Schilängsrichtung in a simple manner ,

How best Fig. 3a it can be seen, the rear end portion 6 of the support body 4 may be supported with its underside 11 almost over the entire surface or over the entire longitudinal extent on the Schioberseite. In the execution according to Fig. 3a Thus, the rear end portion 6 is fixed such that relative movements between the rear end portion 6 and the ski 1 are permitted as a result of bends or bends of the ski body. This so-called free-running holder is accomplished by means of a relative displacements allowing coupling. In particular, the rear end portion 6 of the support body 4 is supported by a fastening device 42 relative to the Schioberseite load-transferring, but supported in the longitudinal direction free-lance and secured by means of the fastening device 42 against lifting from the Schioberseite. Conveniently, a bracket, bracket or clamp-like fastening element 43 is provided, which surrounds or passes through the support body 4 at its rear end portion 6 and is rigidly bolted to the ski 1. In particular, the fastening device 42 is designed such that relative movements between the fastening device 42 and between Fastening element 43 and the support body 4 are permitted in the longitudinal direction of the ski when the ski body is subjected to a sag or bending. In contrast, the fastening device 42 prevents relative movements between the support body 4 or its rear end portion 6 and the ski 1 in all directions transverse to the ski longitudinal axis.

The stiffness of the support body 4 made of plastic is in any case dimensioned such that the support body 4 with respect to deflections has a significantly lower flexural rigidity, as the ski 1 within its longitudinal section to the support body 4 congruent. That is, the ski 1 per se within the binding mounting zone provides a much higher resistance to elastic deflection than the support body 4 arranged or fastened in the binding mounting region on the ski side.
