    [0001] TECHNICAL FIELD OF THE INVENTION The present invention relates to an attachment for cross-country skiing, telemark skiing or cross-country skiing with "Step in" automatic locking. State of the art Traditionally bindings ski touring, ski telemark or cross-country ski require unlocking manipulation to open the binding or preparation to allow the establishment of the shoe. In addition to opening the attachment, it is almost always necessary to perform a manual intervention directly with the hand or through a ski pole to lock the boot on the ski. In telemark, the most used materials are bindings according to the "standard 75", such as the fasteners described in US Patent 7,401,802 (Black Diamond Equipment). This type of attachment is characterized by a fixed front grip that maintains the shape called "duckbill" located at the front of the shoe and a cable tension system equipped with spring locking on the heel of the shoe. This shoe standard makes it difficult to walk on rock when climbing, does not allow the use of standard glacier crampons and limits the use of this type of shoe to only telemark ski. In addition the establishment of shoes in bindings is always very delicate. The skier is often forced to kneel to block the ski and be able to lock the tension system on the heel of the shoe. These operations are made more difficult in the presence of snow, because the skis are rarely equipped with stop ski, they slide easily making sometimes the locking operation tedious. Finally, the heaving in the event of a fall is practically impossible, and the use of these bindings thus presents a high risk of injury for the skiers. In the mid-2000s, a group of manufacturers defined a new standard, called "New Telemark Norm" or NTN, which sets a new ski / shoe interface standard. The new shoes, defined by this standard, can be used in telemark or downhill skiing, and can receive standard glacier crampons. The sole of the shoe is divided into two parts: the front sole specific to the standard NTN and the heel which is classic and distinct from the front sole. The specificity of the front sole comes from the projection which is located at the level of the plantar arch in the center of the shoe, at the rear end of the front sole. Thus the shoe can be secured to the ski by being held between the front portion of the front sole and the projection. This standard has made it possible to create bindings that combine the freedom of movement of the heel specific to telemark and which incorporate a safety device releasing the boot in case of fall of the skier. Responding to several issues of the Standard 75 standard, these bindings can also include ski stops and provide extra safety for skiers. The telemark bindings as described in EP 1 790 396 (Rottefella) are the fastening models corresponding to the NTN standard. These bindings always require a manual unlocking, a delicate implementation of the shoe and an intervention for the locking of it by hand, with the free foot or with a ski pole. These bindings are also characterized by a weight greater than the average fasteners available on the market.
    [0002] In addition to the development of these bindings, the shoe manufacturers have integrated the front and rear interfaces specific to Dynafit ® fasteners into certain models in their range. These Dynafit ® type interfaces are characterized by the presence of two hollow and conical inserts located on the front tip of the sole and an insert plate on the heel. NTN telemark boots, equipped with these interfaces, allow the skier to use them either on skis equipped with NTN telemark fixation or on skis equipped with Dynafit ® standard hiking bindings. Users really appreciate the versatility of this type of new generation of shoes. The invention described in the present patent application uses this shoe model. Based on this shoe concept standard NTN and equipped with Dynafit ® interface, a model of fixation appeared, associating the front part of the Dynafit ® fixation and the locking tension system on the heel of the clean shoe telemark bindings of "Standard 75". This system maintains the front of the shoe through the flanges (forks) of the binding Dynafit ®, while the tensioning of the shoe is provided by the classic heel strap system maintained by the cable assembly -report telemark bindings under "Standard 75". This system provides a functional and effective telemark, reasonable weight and effective hiking, but still requires a manual lock of the shoe and limits the safety of the skier because of difficult heaving.
    [0003] The problem that the present invention seeks to solve is to allow both an automatic locking of the shoe in the binding, the use of the setting in hiking mode without heaving, an easy release skier actuated and an automatic heaving in case fall, while using a fixation of a total mass as low as possible.
    [0004] Objects of the invention According to the invention, the problem is solved by a ski binding, in particular ski touring, telemark and / or cross-country ski binding, for fixing a ski boot comprising a sole front and a heel, said ski binding comprising: - a front retaining element, adapted to cooperate with the front sole of the boot, - a rear retaining element adapted to cooperate with a projection of the rear portion of the front sole and or with the boot sole of the boot, said rear retaining element being able to pivot, raising or lowering its rear part, in the vertical plane about an axis (which may be a material or virtual axis) horizontal orthogonal to the ski direction between a so-called high position (or "rest position") and a so-called low position (or "engaged position"), - a tensioning element which acts between the rear retaining element and the ski and / or the element of restraint ava nt, able to ensure the tensioning of the boot on the binding and to allow the heel to be freely lifted, said attachment being characterized in that it further comprises: - a tensioning rod placed under the stirrup of rear restraint and connected to the latter, so as to allow said rear retaining stirrup to pivot in the vertical plane about a horizontal axis orthogonal to the ski direction, - a fixed stop (also called "retraction stop") placed on the ski or the front retaining element, adapted to cooperate with the tensioner rod, so as to allow the rear retaining stirrup to move back, by stretching said tensioning element, when the heel of the shoe exerts on the rear retaining caliper being in the rest position a downwardly directed pressure. The front retainer element is advantageously a Dynafit® type fastening system, with a double locking lug on the boot. The front retainer includes a control member, such as a user operable latch, which transmits its movement to the flanges through a forward link. The retraction abutment cooperates with the tensioning rod and transforms during the engagement of the shoe in the rear retaining element the vertical force exerted by the heel of the boot on the rear retaining element in horizontal movement in the rear direction of said rear retaining member, which allows the engagement of said rear retaining member (preferably via a rear catch flange) or on the rear projection of the front flange or on the heel.
    [0005] According to one embodiment of this attachment, the rear portion of said rear retaining clip or said tensioning element is connected to the rear portion of said tensioning link. The tensioner link allows the retainer to pivot between a high position and a low position.
    [0006] The rear retaining clip may be connected to the front retaining member by a flexible connecting member. The latter may have, in its rear part, a guide which slides in the drawer of the rear retaining element. According to another embodiment which can be combined with the previous one, said tensioning link, when the engagement of the rear retaining element, abuts with its front end against said fixed stop. According to another embodiment which can be combined with one or more of the foregoing, when the rear retaining yoke is released from the recoil tension and when the protrusion of the rear part of the front sole or the heel of the boot is inserted in the rear retaining clip, the projection of the rear portion of the front sole or the heel of the boot is supported on a tongue of the link, and locks said link in the retracted position.
    [0007] According to yet another embodiment which can be combined with one or more of the foregoing, the rear retainer is designed such that upon placement of the boot in the rear retainer, after locking of the front retaining element on the front part of the front sole, when the user lowers the heel, the rear soleplate bears on the rear retaining stirrup or a component associated with the rear retaining stirrup, and imposes a retreat of the rear retaining stirrup under the effect of the rod, itself bearing on the fixed stop retraction, so that the retraction of the rear retaining stirrup allows the projection or the heel of the shoe to fit into the rear retainer. According to yet another embodiment that can be combined with one or more of the previous, the rear retaining element further comprises a retraction boss placed behind the fixed stop or integrated in the tensioning rod, able to release the tensioner rod resting on the fixed stop when the projection or heel of the shoe is inserted into the rear retaining clip. According to yet another embodiment which can be combined with one or more of the preceding, said tensioning element comprises two resilient return members (typically springs) disposed on either side of the rear retaining element, and preferably within the rear retaining yoke, and at least one knurled ring for adjusting the preload of the tensioning member, and said tensioning member preferably further comprising a plurality of cooperating rods and cables; with said springs for tensioning the retaining clip. Said rods may be disposed within said springs, typically parallel to the direction of attachment (i.e. parallel to the ski). The cables can be replaced by a hoop. According to yet another embodiment which can be combined with one or more of the foregoing, the attachment comprises a control member (typically a latch) operable by the user, said control member (latch) for holding the rear retaining bracket sufficiently retracted to prevent the projection or heel from being hooked by the rear retaining bracket, either by acting directly on the rear retaining bracket or by acting directly on the tiller. This is suitable for cross-country skiing and ski touring.
    [0008] According to yet another embodiment which can be combined with one or more of the above, said rear retaining clip comprises two lateral stops, disposed on either side of its rear part, so as to center the rear projection of the soleplate. before the boot on said rear retaining yoke, said lateral abutments being preferably arranged so as to be able to pivot each about a vertical axis under the effect of a torque generated by a lateral movement of the boot during the loosening. According to yet another embodiment which can be combined with one or more of the foregoing, the tensioner rod is connected to the tensioning member or the rear retaining bracket via an axis which lies in the plane said tensioning element allowing the rear retaining clip to slide parallel to the plane of said tensioning element.
    [0009] According to yet another embodiment which can be combined with one or more of the foregoing, the front retainer comprises three components, namely a specific element (latch), a slider and a pivoting member; the slider can move fore and aft to release or lock said pivoting member. When the attachment is in telemark mode, the user can rotate the element forward, a protuberance of said member bears on said slide and slides backward, releasing said pivoting member to allow the skier to lift easily the shoe to practice ski touring. The user can switch to "ski touring" mode without taking off.

    [0012] Figure 14 shows a side view of the fastener according to the same variant as that of Figure 13, with the shoe in "telemark" position. Figure 15 shows a detail of the device shown in Figures 1 to 3 which it illustrates the operation.
    [0013] Figure 16 shows a detail of the device shown in Figures 12, 13 and 14 which it illustrates the operation. Detailed Description In this description, the terms "forward", "rear", "front", "behind", "forward" and "backward" refer to the direction of skiing in normal use. As illustrated in FIGS. 1 and 2, the binding 1 according to the invention comprises a front retaining element 2, a rear retaining element 3 and a heel piece 4. These three elements are fixed on the ski, typically by screws 17, directly or via a mounting plate. The main function of the heel 4 (visible in particular in Figure 9) is to allow the positioning of the heel of the shoe on a bearing surface 41 at a specific height; the heel is fixed on the ski by means of a support 40; it can understand in known manner a wedge 43 (called "high wedge").
    [0014] The front retainer 2 is known as such; it may advantageously be a front retainer known from the so-called "Dynafit ®" fastener comprising two conical lugs 20a, 20b which each cooperate with a hollow and conical insert 23 located on the right and left side of the front part of the front sole 11 of the shoe 5. The front retainer 2 in the "open" position (disengaged) is actuated by advancing the tip of the front sole of the shoe 5, via the connecting rod before 21, as will be described below. Said pins 20a, 20b are each mounted on a flange 24, which is actuated by the front link 21; in the engagement position of the front retention element 2, these flanges 24 bring the lugs 20a, 20b laterally to the front portion 14 of the front soleplate 11, so as to allow the lugs 20a, 20b to fit into said Hollow inserts 23. Thus, the front retaining element 2 makes it possible to retain the boot 5 in a position that allows, when the rear sole 13 of the boot 5 is not held in a low position and can be lifted, the easy tilting the front portion 14 of its front sole 11 around a horizontal axis, orthogonal to the long direction of the ski; this axis passes through the lugs 9a, 9b.
    [0015] Any other type of front retainer 2 which allows easy tilting of the front portion 14 of the front sole 11 about a horizontal axis, orthogonal to the long direction of the ski can be used in the context of the present invention. Preferably, this front retention element 2 is designed so as to allow the disengagement of the front portion 14 of the front sole 11 of the boot 5 by a control element (typically a latch) 26 actuated by the skier by hand or with pressure from the tip of the stick.
    [0016] In the example of the Dynafit ® type front retainer, to disengage the boot from the front retainer 2, the front retainer 2 can be actuated by a control member (here a latch). which actuates a link before 21; said control member (latch) 26 can be operated by the skier by hand or exerting a substantially vertical pressure with the tip of his stick; to easily accommodate this tip of the stick the latch 26 may have a hollow area 22. This manual or stick actuation causes the opening of the front retainer 2 which releases the front sole 11 of the shoe 5. This is in the rear retention element 3 that resides the present invention. It comprises a rear retaining stretcher 7 connected to a link rod 6 called a tensioning link, said rear retaining stirrup 7 being in its rear part integral with a rear attachment strap 8 adapted to hook to the rear projection 46 of the soleplate. 11. The rear retaining element 3 further comprises a tensioning element 35 which typically comprises at least one spring 31 (or another elastic return member) and one or more transmission elements, for example a system comprising rods 32. and at least one cable 33 (visible in FIG. 3). The rear retaining clip 7 can switch between a high position called "rest position", illustrated in FIGS. 4 and 5, and a low position called "locked position". 9 This tilting is guided by a link 6 called "tensioning rod" positioned under the rear retaining clip 7. The rear part of the rear retaining clip 7 is connected movably at the rear end of the tension rod 6. The front end 74 of the tensioning rod 6 can be engaged in a fixed stop 16, fixed on the ski. When the skier lowers the heel 12 of his shoe 5, this downward vertical movement engages the front end 74 of the tensioner rod 6 in the abutment 16 and causes the rear retaining stirrup 7 to recoil. This recoil motion tensioning the tensioning element 35; it allows the engagement of the rear protrusion 46 of the front sole 11 by the rear hook strap 8 of the rear retaining bracket 7. In addition to the front retaining element 2 and the rear retaining element 3, Figure 3 shows the various components that form the tensioning element 35: the rods 35 and the cable 33, as will be explained below.35 The tensioning rod 6 can be equipped with an elastic return member ( typically a spring) which presses it downwards. We now give a precise description of the operation of the fastener 1 according to the invention, and in particular of its rear retention element 3, with particular reference to FIGS. 6 to 9 In the rest position of the fastener 1, the element of retainer before 1 is in the open position (for example, in a Dynafit ® type front retaining element 1, the flanges 24 are open), and the tensioning rod 6 and the rear retaining clip 7 are in the raised position (raised position ): the rest position is the position in which the attachment 1 is ready to be paved. Figure 6 shows more particularly the rest position for the rear retention element 3 according to the invention. When the user has engaged the front retainer 2 (i.e., in the example of the Dynafit ® retainer described above: locked the flanges 24 from the front to the using the lugs 20a, 20b which cooperate with the hollow inserts 23 of the shoe 5), it suffices to lower the heel 12 to lock the shoe 5 in the rear retaining member 3 according to the invention. When the skier lowers the heel 12 of his shoe 5, the rear sole 13 of the shoe 5 is supported on an interface piece (not shown in the figures) or directly on the rear retaining clip 7 and imposes de facto the tensioning rod 6 to bear on the fixed stop (also called retraction stop) 16 (see Figure 7). Under the vertical force imposed by the shoe, the link 6, bearing on the retraction abutment 16, exerts a horizontal force on the rear retaining stirrup 7 directed rearwardly and imposes a recoil motion of the latter . This backward movement of the rear retaining stirrup 7 actuates the tensioning element 35 of the rear retaining element 3. (This forward and backward movement of the rear retaining stirrup 7 may be noted in the figures in Figures 6 to 10 by the extent of the space symbolized by the arrow E). More precisely, this recoil movement puts the internal springs 31 of the binding in tension. The recoil movement of the rear retaining yoke 7 continues until the projection 46 of the rear portion of the front soleplate is inserted into the rear hanger 8 (Figure 8). When the rear retaining bar 7 arrives in the retracted position, allowing the boot 5 to fit (in an advantageous embodiment of the rear retaining member 3 this allows the projection 46 to be engaged by the flange 8), a suitable protrusion boss-type 10 located on the ski or an element 76 of the attachment, such as on the retraction abutment 16, retracts the tensioner rod 6 by exerting a force directed upwards on the front portion of the tensioning rod 6. This retraction of the rod 6, which is typically around a horizontal axis 19, releases the retaining clip 7 of the recoil tension. The retaining stirrup 7, under the effect of the tension of the tensioning element 35, returns to the rest position and puts the shoe 5 into tension. In this situation the shoe 5 is locked on the ski binding 1, and the skier can indulge in telemark, knowing that the rear sole 13 of the shoe 5 remains fixed in the rear retaining clip 7 and can be raised by tilting it upwards; this movement will be more effective with a telemark ski boot whose shell, especially on the front, is sufficiently flexible.
    [0017] In one embodiment, the fixed stop 16 is fixed on the ski. In another embodiment it is integral with the front retention element 2. To remove, the skier will simply release the portion of the front sole 11 of the shoe 5 held by the front retainer 2, typically by exerting vertical pressure with its stick on the latch 26. In the case of the Dynafit ® type front retaining element 2, described above, when the skier actuates the control element 26 (in the example, when the skier presses the latch 26), the flanges 24 deviate on both sides of the front sole 11, thus releasing the front portion 14 of the front sole 11 by disengaging the lugs 20a, 20b, releasing the front tip of the shoe. The shoe 5 is no longer maintained, it is sufficient for the skier to advance slightly his shoe to clear the heel or projection 46 and remove his shoe 5 from the attachment 1. When the projection 46 of the rear portion 15 of the sole before 11 fits into the rear socket, it bears on the tongue 36 of the link 6 and blocks it in the retracted position.
    [0018] In an embodiment illustrated in FIGS. 5 to 9, a retracting boss 10 is provided under the tensioning rod 6, which strengthens the tension of the tensioning element 35 of the rear retaining element 3. According to a particular embodiment embodiment, the tensioning springs 31 of the tensioning element 35 are integrated in the rear retaining clip 7.
    [0019] In one embodiment, the rear retaining element 3 is pivotable, raising or lowering its rear portion, in the vertical plane about a horizontal axis orthogonal to the ski direction between a high position and a low position. . This axis can be a hardware axis and / or a virtual axis. A virtual axis may be represented by a flexible material, in this case a flexible connecting element 30. Such a flexible connecting element may exhibit during its operation a generalized and / or localized deformation, for example by means of one or more grooves 75 (see Figures 3 and 4), and / or it can be fixed at its front end by an axis 37. In an embodiment illustrated in Figures 3 and 4, the dimensions of the element of flexible connection 30 are chosen so as to ensure that the rear retaining stirrup 7 is in a position such that the tensioning rod 6 is placed downstream of the fixed abutment 16. In one embodiment illustrated in FIG. 1 of ski according to the invention comprises a control element 45 which can be actuated by the user, said control element 45 making it possible to impose on the rear retaining clip 3 a position sufficiently far back to prevent the 46 or the heel 12 to be hooked by the rear retaining clip 7, either by acting directly on the rear retaining clip 7 or by acting directly on the tensioning rod 6. Said control element 45 may be a latch . This makes it possible to pivot the rear sole 13 of the shoe 5 freely upwards; the shoe 5 being held only by the front retention element 2. This pivoting movement is symbolized by the double arrow in Figure 10. This position is suitable for cross-country skiing or ski touring. The control element or latch 45 can advantageously be arranged between the rear retaining element 3 and the heel piece 4.
    [0020] As mentioned above and illustrated in FIG. 11, the retraction boss 10, which is optional, can be located either on the ski or on the base 76 which includes the retraction abutment 16, as shown on FIG. Figure 11a (as well as in Figures 5, 6, 7, 8 and 9), or it can be integrated in the tensioner rod 6, as shown in Figure 11b. In the latter case it may be a protrusion directed downwards which cooperates with the surface of the base 76, or any other equivalent system. FIGS. 12 to 14 and 16 illustrate five variants of the invention that can be implemented separately or, as in the embodiment shown in FIG. 12, together: In a first variant, the flexible connecting element 30 integrates a guide 29 which slides in the drawer of the rear retaining clip 7. The guide 29 stiffens the lateral resistance: it can be made of plastic. In particular, this variant has the advantage of ensuring better lateral stability of the boot 5 during the heaving, when the front part of the boot is no longer held by the front retention element 2.
    [0021] In a second variant whose operation is illustrated in FIG. 14, in the tensioning element 35, the cables are replaced by a hoop 77; this makes it possible to control the point of inflection of the shoe.
    [0022] In a third variant illustrated in FIG. 16, in the front retention element 2, the flanges 24a, 24b have a bearing surface 78a, 78b for the front part 15 of the front soleplate 11.
    [0023] In a fourth variant whose operation is illustrated in FIGS. 13 and 14, the cooperation between three components of the front retention element 2, namely the "hiking mode" control latch 49, the slider 47 and the pivot assembly Hike 50 allows the user to switch from "ski touring" mode (figure 13) to "telemark" mode (figure 14) and vice versa without taking off. This fourth variant represents an innovative modification of the front retention element 2; it offers a new feature which will be explained below in connection with FIG. 16. The hiking mode control latch 49 is dissociated from the front link 21 'but still provides the locking function of the front link 21' for the tour mode but it now makes it possible to slide the slide 47 from front to back to release or block the hitch pivot assembly 50 The hitch pivot assembly 50 which was blocked by the hiker slide 47, can now pivot about the axes (82), see Figure 16f. When the attachment is in telemark mode, the user can rotate the member 49 forward, a protuberance of the workpiece bears on the slider 47 and slides backward, thereby releasing the pivot assembly 50. This free set allows the skier to easily lift the shoe for hiking as described in Figure 13. The user (skier) can switch to "ski touring" mode without taking off. Furthermore it is noted that in Figure 12 the plate 27 was made in two parts 27,27a. In this sub-variant, the main body 27 is placed on a shim (for example plastic) 27a which incorporates guides in the middle part to ensure the maintenance of the slide 47 during sliding. This sub-variant makes it possible to limit the cost of machining.
    [0024] Note that the embodiment of Figure 12 does not show the presence of the retraction boss 10, but it is expected that the latter can be added.
    [0025] In a fifth variant, the front link (noted here 21 ') and its latch (denoted here 26') are integral.
    [0026] Figure 15 illustrates otherwise the embodiment of Figures 1, 2 and 3. Figure 15a shows the attachment in the open position, waiting for the shoe. The flanges 24a, 24b are open and the front link 21 is in the up position. FIG. 15b shows the fastening in the "shoe in front" position; it's the telemark position. The front link 21 has tilted down; the latch 26 has followed the tilting of the front link 21 (these two parts being connected by a pivot and a position locking system) caused by the engagement of the tip of the shoe. Figure 15c shows the attachment in "hiking" position. The latch 26 has been tilted by the skier by hand (typically by pressing the tip of the stick on a hollow area 22 of the latch 26) and bears on at least one bearing protrusion 48 (here: two protuberance of support 48a, 48b). The binding is blocked and the skier can not take off in this position. Figure 16 illustrates otherwise the embodiment of Figures 12, 13 and 14. Figure 16a shows the front retainer 2 of the attachment in the open position, waiting for the shoe. This figure incorporates the embodiment in which the front link 21 'and its latch 26' are integral (called in the description which follows "part 21 '+ 26'"). Figure 16b shows the attachment in the "telemark" position. The part 21 '+ 26' has tilted downwards with the bearing surfaces 78a, 78b of the flanges 24a, 24b. Room 49 did not move; it is independent of the room 21 '+ 26'. In this condiguration of the fixation the skier can take off. Figure 16c shows the attachment in the "Hiking" position. The piece 49 was tilted by the skier, typically by a downward vertical pressure exerted before the pint of his stick. The binding is blocked and the skier can not take off.
    [0027] Figure 16d shows in more detail the movement of the part 49 and the slide 49: the lowering of the part 49 causes the retraction of the slide 47 in the direction of the arrow. A bearing surface 80 of the front link 26 'locks the part 21' + 26 '. When the slider 47 has slid backwards the piece 49 is free to pivot upwards. The pivot point for the "telemark" mode is close to the point of clamping of the shoe, and the shoe can rotate by greatly limiting the tesnsion springs: When the skier raises his heel the shoe pivots and performs a bow movement of circle. The rear retainer 3 also pivots around a pivot point and thus performs a circular arc movement. In telemark mode (part 49 locked on the ski) this pivot point is away from the front retainer 2.; this gap causes a strong tension of the tensioning element 35 and bends the shoe. The two circular arcs described by the movements of these two elements are remote, the tensioning element 35 compensates for the difference and thus increases the tension. In "if hiking" mode (part 49 unlocked) the pivot point of the rear retaining element 3 is very close to the front retaining element 2 because the part 49 pivots with the rear retaining element 3 (see FIG. Figure 13). The tension on the shoe is lower, the skier can easily lift his heel for ski touring. This variant of the front fastening element 2 thus allows easy passage of the "telemark" mode in "hiking" mode and vice versa without disassembly of the shoe, with the aid of a simple action by the tip of the stick on the Element 49.
    [0028] FIGS. 16e and 16f show more clearly the structure and the action of the slide 47 and the "pivot pivot assembly" piece 49. FIG. 16e shows the piece 49 in blocked mode, FIG. 16f shows the released piece 49 after the slider 47 has released it; in this example, the slide cooperates for this purpose with a notch 81 arranged in the piece 49. The latter can pivot about an axis 82.
    [0029] In Figures 1 to 10, 11b, 12 to 14 and 16 appear screws 17 for fixing the various elements on the ski, but the ski 28 is shown only in Figure 11a. The shoe 5 has been described here as comprising a front sole 11 and a rear sole 13, these two parts being separated by the projection 46. In the context of the present invention, the projection 46 can also be made in the form of a channel or any other hollow formed in the sole of the shoe, in which case the projection 46 is said, in the context of the description, belong to the front sole 11 which it represents the edge of the rear portion 15; the rear sole 13 is in this case represented by the portion of the sole which extends from the projection 46 to the rear end of the sole (called the heel 12). In another embodiment not illustrated by figures, it is the heel 12 which is engaged by the rear fastening element 7. The binding according to the invention has many advantages. It can be engaged and disengaged without the skier needing to bend down. In addition it is versatile, robust, reliable, lightweight.
