Description

The invention relates to a snowboard boot, in particular snowboard touring boot, according to claim 1.

In addition to skiing, snowboarding is another popular winter sport. Here, both feet of a snowboarder are attached via a binding on top of a sliding board, also called snowboard, which can slide downhill on a snow surface with its underside. There are known special snowboard boots, which are suitable for attachment to or in the binding and allow good power transmission for precise control of the snowboard and a good thermal insulation. Such snowboard boots are available either as relatively soft soft boots or as relatively stiff, designed as hard shell shoes, hard boots available.

Similar to ski touring, snowboarding off groomed slopes is becoming increasingly popular. Here mountains or slopes are climbed on foot in the ascent, before they are driven off in the downhill with the snowboard. For divisible snowboards, so-called splitboards are known, which are usually dismantled for the ascent in two ski-like parts and for the downhill again to a single snowboard composable. For the ascent, skins are glued to the undersides of both splitboard parts which, while allowing for sliding forward, especially uphill, prevent slipping back, especially downhill. Bindings for snowboards, especially splitboards, are known which have a climb mode and a downhill mode, with a left and right foot binding element each mounted on a ski-like part of the splitboard and the binding elements for downhill as stiffening fasteners serve the parts of the splitboard.

Snowboard boots are known from the prior art, the shaft, which rests on the lower leg of a snowboarder, is slightly inclined forward so that the snowboarder can take a optimized for the downhill posture, in which the knees are pushed in the direction of the toes forward can. In this way, a lower body position is enabled, which allows better power transfer to the edges of the snowboard in the downhill and precise control of the snowboard.

It is known ski boots, especially ski touring boots to perform switchable between a driving mode and a walking mode. In walking mode, the rear shell element of the hard plastic shell of the ski boot can be folded slightly backwards via a hinge and, in the driving mode, can be locked in a forwardly inclined driving position. As a result, the climb is facilitated when touring and still provided for the descent as stiff as possible ski boots.

For snowboard boots, especially snowboard soft boots, there is the disadvantage that the step length of a snowboarder is limited by the forwardly inclined shaft position of conventional snowboard boots. In the ascent, for example, with a previously described ski-like converted splitboard, especially in flat pieces, a snowboard tourers would like to push forward as fast as possible on a part of the splitboard with a binding element in a snowboard boot to accelerate forward. The snowboarder is limited in its stride length, even when wearing a soft boot, because of the snowboard boot that slopes forward. In addition, in the area of the calf, uncomfortable pressure points can arise due to pressure of the upper edge of the upper leg on the calf back, in particular in the case of a slightly larger step forward. In the prior art, no snowboard boot is known, which satisfactorily solves the problems mentioned when climbing with snowboard boots, in particular with a splitboard.

The present invention therefore has the object to provide a snowboard boot, which allows a greater step length in the climb, in particular without thereby disadvantages for the downhill properties, in particular with regard to the stiffness of the snowboard boot to bring. In addition, a more comfortable ascents, especially without strong pressure on the calf to be made possible without sacrificing stability and precision when driving off the snowboard.

This object is achieved by a snowboard boot, in particular snowboard touring boots, according to claim 1.

The object is achieved, in particular, by a snowboard boot, in particular a snowboard touring boot, which comprises a shaft section which at least partially encloses a lower leg of a wearer and a heel section which receives a heel of the wearer, wherein the shaft section is designed so flexibly at least in regions on the back in that the lower leg of the wearer is substantially free to move forwards and backwards within a predetermined angular range relative to the vertical.

A snowboard boot may in particular be understood to mean a soft boot that can be fastened in a snowboard binding, for example via ratchet straps, in particular is festschnallbar, and is stabilized in particular in the rear area by a high back of the binding. There are conceived for different types of binding snowboard boots invention, which can be particularly adapted to special splitboard bindings, which for example, particularly easy to run, optimized for easy conversion or can be suitable for the use of crampons, can be coordinated. Snowboard boots, especially snowboard touring boots, can be equipped with a rubble band and / or a tread sole and preferably be crampon resistant.

A snowboard boot can be designed with or without an inner shoe. For the purposes of the invention, only the outer shell of a snowboard boot could be understood as the snowboard boot, in which in particular an inner boot is accommodated. The term "snowboard boots" may also refer to a unit of an outer shell and an inner shoe under certain circumstances.

The term "carrier" can be understood as meaning a snowboarder or snowboarder, in particular a snowboard tourer, who wears the snowboard boot according to the invention during ascent and / or downhill during a snowboard tour, in particular with the splitboard.

A heel section may be understood as the zone of the snowboard boot, in particular an outer shell and / or an inner boot of the snowboard boot, in which the heel of the wearer is in a tightened, in particular laced, state of the snowboard boot, that is to say in particular the lower rear region of the snowboard boot above the sole. The shaft portion may be understood to mean the zone of a snowboard boot, in particular the outer shell and / or the inner boot of a snowboard boot, which at least partially surrounds the lower leg of a wearer in a tightened, in particular laced, state of the snowboard boot, the shaft portion particularly in the front lateral region of the boot Shin can overlap with a tongue section. The shaft section can also laterally enclose the ankle of the wearer, wherein the shaft section preferably merges into the heel section in the area of the ankle. On the back of the snowboard boot, the heel section at its upper end in particular passes directly into the shaft section. The shaft portion extends in particular from the region in which the Achilles tendon of the wearer is located up to the upper edge of the snowboard boot in the region of the calf of the wearer. In particular, the shank portion comprises the part of the snowboard boot, which in a displacement of the knee of the wearer forward, ie in the direction of the toe, or to the rear, ie in the direction of the heel of the wearer, by a force on the lower leg or the Schien- or Fibula of the wearer performs a movement, in particular rotational or tilting movement, forward or backward relative to the preferably stationary heel section. In this case, the snowboard boot can be deformed, in particular partially compressed or stretched.

Single or multiple areas of the shaft portion may be formed on the back, so on the back of the snowboard boot, flexible. A flexibly formed region of the shaft section can be achieved for example by a suitable structural design, in particular by suitable shaping, in particular incisions, a reduced wall thickness of the shaft section or articulated elements, the use of soft, flexible, elastic or elastic construction materials or other constructive measures. The shaft and / or the heel portion may comprise reinforcing elements, for example made of leather, plastic or fiber-reinforced materials. In particular, the heel portion may comprise a heel cap sewn on, for example, which may also extend to parts of the shaft portion.

In particular, a substantially unimpeded movement refers to a movement that occurs without much effort compared to the internal friction or spring forces of the snowboard boot, for example by rubbing together or deformation of different layers of material, for example between the outer shell and an inner boot or within the shaft portion or inner boot Carrier is executable. Substantially unhindered can also mean unhindered, free or easy in the sense of without substantially noticeable counterforce or noticeable, in particular mechanical, blockage for the wearer. In particular, a wearer can easily move his lower leg, especially when ascending, within the predetermined angular range from the front to the rear, when the snowboard boot according to the invention, preferably at least one inner boot, is loosely or firmly laced.

The vertical may be understood to mean a perpendicular to the sole of the snowboard boot or to the surface of the snowboard in which, in particular, an imaginary center line of the wearer's lower leg would run if it is in a neutral upright position, without being forward or backward in the original or in the front To lean back reserve. A predetermined angular range is preferably to be understood as meaning a certain amount of an angle between a forward angular position and a rearward angular position in which the lower leg of the wearer is tightened Condition of the snowboard boot can be brought or moved between these back and forth. In particular, the highback of a snowboard binding is also correspondingly flexible, so that it does not block the movement of the lower leg over the predetermined angular range.

Such a snowboard boot according to the invention has the advantage that the stride length of the wearer, in particular during ascent or in a flat piece during a snowboard tour, can be extended compared to a conventional snowboard boot. In particular, by a rear-side flexible design of the shaft portion, the wearer can move the foot forward relative to the knee or the knee relative to the foot to the rear substantially unhindered and thereby perform a larger step, without the shaft portion blocking this movement. This can also be a particular unpleasant pressure on the calf or the lower leg of the wearer can be prevented if it performs a step forward or pushes a ski-like part of the splitboard with his foot forward.

In an advantageous development of the invention, the shaft section has at least one, preferably V-shaped, recess on the back side of the shaft upper edge, which extends in particular towards the heel section, for example up to the upper end of the heel section. The incision is in particular designed as a recess in the back of the snowboard boot, preferably in its upper, in particular the outer shell of the snowboard boot. In particular, the incision is designed as a slot between a first and a second lateral shaft section, wherein the incision preferably tapers from the upper edge of the shaft downward, that is to say in the direction of the heel section. A lateral shaft section can be understood in each case as the upper, in particular rear, region of the shaft section on the inside and the outside of the snowboard boot. The incision need not necessarily represent a free interruption in the circumferential direction of the shaft portion, but may also be executed only in one or more layers of the shaft portion, for example, by partially recessing individual particular stiffening layers in the preferably layered structure of the shaft portion. The incision can also be closed or clad again by inserting a preferably extensible material between the lateral shaft sections. In particular, the load-bearing, stiff upper material of the snowboard boot could be cut from the upper edge of the shaft, wherein subsequently a thin, preferably elastic textile material could be sewn into the incision, in particular to prevent the penetration of snow into the snowboard boot from behind. The incision may extend over the entire height of the shaft portion, or only over part of it. The incision can be V-shaped, U-shaped, rectangular or in any other form. Preferably, only the outer shell of the snowboard boot is cut, while the inner boot shaft of an inner boot is not cut. Such an incised snowboard boot is simple and inexpensive to produce and also has the advantage that the shaft portion is flexible on the back due to its shape and the lower leg of the wearer is movable backwards.

In an advantageous development of the invention, the shaft section encloses the inner shoe upper of an inner shoe at least partially and the inner shoe shaft is substantially unhindered relative to the vertical within a predetermined angular range, in particular relative to the shaft portion, forward and backward. Preferably, the inner boot is designed as known from the prior art, while the shaft portion of the snowboard boot, according to the invention is flexible. In this way, with a movement of the lower leg of the wearer from front to back or vice versa, a relative movement between the inner boot shaft and the outer shaft portion of the Snowboardstiefels would arise, which depends in particular on how tightly the inner boot encloses the lower leg and the inner boot laced is, if this is separately laced. Such an embodiment has the advantage that the thermally insulating, stabilizing and comfortable for the wear comfort properties of the liner remain intact, while the desired mobility of the snowboard boot is achieved in particular to the rear by a flexible design of the outer shaft portion.

In an advantageous development of the invention, two lateral shaft sections separated from one another by the incision, in particular by the inner shoe shaft, are pushed apart laterally when the lower leg is in a rear angular position. A first and a second lateral shaft portion are not necessarily formed symmetrically to each other, but preferably the incision is centered, so along the median plane of the snowboard boot executed. By tilting the lower leg or the inner shoe back to the rear of the first and the second lateral shaft portion are pushed apart or spread apart, with a V-shaped incision, the spread is greater, the deeper the incision is. In particular, is about the depth and shape of the incision, ie in particular the length of the incision starting from the upper edge of the shaft, the maximum rear angular position at least partially predetermined. In this advantageous embodiment, the shaft portion is flexible in the lateral directions, whereby the desired mobility of the lower leg and the inner shoe is achieved to the rear.

In an advantageous development of the invention, a fixing device, preferably comprising a belt, is attached to the shaft section in order to fix the shaft section, preferably in that the fixing device holds the lateral shaft sections together. In particular, a fixing device, preferably comprising a belt, is attached to the shaft portion to fix the inner shoe shaft in a forward angular position. With the aid of a fixing device, the snowboard boot can be transferred from a walking mode or a climbing mode to a driving mode or downhill mode, in particular by the fixing device being open in the walking mode and being closed in the driving mode. In the driving mode, the shaft portion is fixed, so that the snowboard boot does not allow, or only a very limited, movement of the lower leg from front to back. In walking mode, however, the shaft portion is not, or only partially, fixed, so that the snowboard boot allows movement of the lower leg from front to back, or vice versa. In the case of an existing innerboot, the innerboot shaft can be fixed by the fixing device in a front angular position, wherein a maximum front angular position can be predetermined by the tongue portion of the Snowboardstiefels and in particular corresponds to the angular position of the lower leg in the driving mode. The fixing device may comprise a closure mechanism, which is based, for example, on a rotation, a latching, a displacement or an insertion of a closure element, and in particular a molded part, preferably made of plastic. For example, the fixing device may comprise a hook-and-loop fastener, a ratchet, a zipper or a lacing system. In particular, the degree of fixation can be adjusted continuously. Preferably, the fixing device in the upper region of the shaft portion, ie in the region, in particular just below, the upper edge of the shaft, is arranged.

Preferably, the fixing device is designed as a belt extending in the circumferential direction of the shaft portion, in particular transversely to the incision, from the side of the first lateral shaft portion to the second lateral shaft portion and in the tensioned state holds together or compresses the lateral shaft portions, so that pressing apart the lateral Shank portions is prevented, whereby a movement of the lower leg or the inner shoe shaft is blocked to the rear. The belt may be fastened to a lateral shaft section, or it may be designed to encircle the shaft section circumferentially with itself. A fixing device has the advantage that the carrier can choose between a walking mode and a driving mode of the snowboard boot, in particular by opening or loosening or closing or fixing the fixing device. As a result, the snowboard boot on the one hand optimal downhill properties with fixed shaft portion and on the other hand optimal ascent properties in a non-fixed or flexible shaft portion.

In an advantageous embodiment of this development, the fixing device has an eyelet into which a belt fastened to the shaft portion, in particular a hook-and-loop fastener belt, can be threaded. In particular, the snowboard boot may comprise at least one hook-and-loop fastener belt which is designed as a powerstrap and, as an alternative or in addition to a lacing on the front side of the snowboard boot, binds or braces two lateral shaft sections, in particular in overlap with a tongue section. A hook-and-loop fastener belt threaded through the eyelet of the fixing device could in this way simultaneously fix the front and the rear of the snowboard boot. Optionally, if the hook-and-loop fastener strap is not threaded into the eyelet, only the front portion of the snowboard boot could be fixed while the shaft portion is back flexible and in particular the fixator is loosened. A fixing device of this embodiment is sturdy and easy to operate and allows variable adjustment of the snowboard boot with respect to the mobility of the lower leg forward and backward.

In an advantageous embodiment of the invention, a movement limiting device is mounted on the shaft portion, which is designed to define a maximum rear angular position, preferably adjustable. A movement limiting device can be understood as a kind of stop element which only allows a certain amount of movement of the lower leg or of the inner shoe shaft to the rear and blocks a further movement beyond that. In this way, the movement limiting device defines a maximum rear angular position, which can be adjustable. Preferably, the limiting movement device is designed as a, in particular length-adjustable, belt loop, preferably made of a belt or strip material, whose one end is attached to the first lateral shaft portion and the second end to the second lateral shaft portion. In particular, the movement limiting device is designed to be uniform with the fixing device. For example, a belt of the fixing device can also serve to limit the movement. For example, a predetermined movement of the lower leg or of the inner shoe shaft towards the rear can be admitted by way of a hook-and-loop fastener belt, in particular a power strap, threaded into an eyelet of the fixing device but not tightened tightly. A movement limiting device has the advantage that the snowboard boot exerts a resistance force on the lower leg of the wearer when the latter inclines too much backwards. Thus, the support during touring, especially after a long step forward for the wearer is facilitated, so that it can initiate the next step with the least possible effort.

In an advantageous development of the present invention, a rearwardly movable support strip extends back along the shaft section, in particular at least up to a shaft upper edge. Preferably, the support strip is attached to the upper end of the heel portion. In particular, the support strip is made in one piece with a heel cap, wherein it forms a preferably a tongue or tongue-like extension of the heel counter in the direction of the upper edge of the shaft. Preferably, the support strip is made of a stiffer material than the flexibly formed portion of the shaft portion. For example, the support strip, in particular just as the heel counter, made of leather, but may also contain reinforcing or resilient plastic, metal or fiber-reinforced elements. In particular, the support strip may act as a previously described movement limiting device, in particular in cooperation with a described movement limiting device, preferably a belt loop. In particular, the support strip can be made so wide that it completely or partially covers an incision in the shaft portion and in particular can prevent or at least make it more difficult for snow to penetrate into the incision. The support strip is in particular in the transition region between the heel section and the shaft portion movable back and forth, in particular hinged, attached to the outside of the snowboard boot and adapted to the mobility of the shaft portion, in particular to the predetermined angular range. In addition, a support strip has the advantage that it can increase the rigidity, in particular torsional rigidity, of the shaft portion, in particular in the driving mode.

In an advantageous development of this embodiment, the support strip, in particular by the fixing device, preferably by an essentially transverse to the support strip belt, at least partially fitting to the shaft portion fixed. By a fixation, in particular a pressing, of the support strip to the shaft portion, the rigidity of the shaft portion is increased, in particular to the rear. In addition, the torsional rigidity of the shaft portion is increased. In this way, the snowboard boot is stabilized or stiffened overall in a drive mode.

In advantageous developments of the two previous embodiments, the support strip at least partially conceals the incision. In particular, the support strip overlaps at least partially with the lateral shaft sections. By sufficient width and / or tailored to the incision shape of the support strip can cover the incision, especially in the driving mode and prevent penetration of snow. By overlapping with the lateral shaft sections, the best possible tightness and high rigidity of the snowboard boot can be achieved.

In advantageous developments of the three previous embodiments, the shank portion, in particular the lateral shank portions, is flattened on the back, so that the support strip in a front angular position rests at least partially flat against the shank portion. By a flattening of the shaft portion on the back creates a widened bearing surface or contact surface for the support strip. In this way, a particularly good adhesion between the support strip and the shaft portion, in particular the lateral shaft portions possible. As a result, in particular the tightness against penetrating snow and the rigidity, in particular torsional rigidity, of the shaft section are improved.

In an advantageous development of the present invention, the angular range between a front angular position and a rear angular position is between 15 ° and 30 °, in particular between 20 ° and 25 °, preferably approximately 23 °. As a front angular position, a maximum front angular position can be understood, which is achieved, for example, when the snowboard boot, especially when the fixing device is closed, in the driving mode. As a rear angular position can be understood in particular a maximum rear angular position, which is achieved, for example, in the walking mode, in particular when the fixing device is open, understood. This predetermined angular range allows a power-saving and comfortable climb and at the same time a precise controllable downhill for a wearer of the snowboard boot, because both a sufficient movement of the lower leg backwards in the climb, as well as a sufficient Slope forward of the lower leg is ensured for an optimal departure position.

In an advantageous embodiment of the present invention, the angular range between the vertical and a rear angular position between 10 ° and 20 °, preferably in about 15 °. By a maximum angle of the lower leg to the vertical of about 15 ° to the rear, the step length can be increased in the rise and faster walking is possible.

In an advantageous embodiment of the invention, the angular range between the vertical and a front angular position between 0 ° and 8 °, preferably in about 6 °. With a front angular position of about 6 °, the lower leg of the wearer is in an optimal downhill position.

Embodiments of the invention are explained below with reference to the drawings. Hereby show:

1a a schematic side view of an embodiment of a snowboard boot according to the invention with a sketched lower leg in a front angular position;

1b the embodiment of a snowboard boot according to the invention 1a with a sketched lower leg in a rear angular position;

2 a schematic representation of an embodiment of a snowboard boot according to the invention in a perspective rear view;

3a a schematic representation of an embodiment of a snowboard boot according to the invention with closed fixing device in a side view;

3b the embodiment of a snowboard boot according to the invention 3a with opened fixing device in a side view;

3c the embodiment of a snowboard boot according to the invention 3a or 3b in a side view of the inside of the snowboard boot.

In the following part of the description of the invention, the same reference numerals are used for the same and like elements.

1a and 1b show an embodiment of a snowboard boot according to the invention 1 , especially snowboard touring boots, in schematic side views. The lower leg 2 a carrier of snowboard boot 1 , ie in particular a snowboard touring ski, is indicated by dashed lines. The snowboard boot 1 includes a sole 19 , a heel section 11 and a shaft portion adjoining above 10 holding the inner shoe shank 15 of the liner 14 encloses and is about at least one lacing system 23 laced. The liner 14 is inside the outer shell 22 added. The heel section 11 takes the heel of the wearer of the snowboard boot 1 on while the shaft section 10 the lower leg 2 the carrier at least partially encloses. The vertical V is perpendicular to the plane 3 in which, for example, the surface of a snowboard runs, on which the snowboard boot 1 could be attached via a binding (not shown). In the present case, the sole lies 19 with her sole surface in the plane 3 , When the lower leg 2 of the carrier is parallel to the vertical V, the carrier is in a neutral upright position. The front angular position W1 is defined in the present case by an angle of 8 ° with respect to the vertical V, but could generally be determined by an angle between 0 ° and 8 °, preferably approximately 6 °. The rear angular position W2 is defined in the present case by an angle of 15 ° with respect to the vertical V, but could generally be determined by an angle between 10 ° and 20 °, but is preferably approximately 15 °.

The shaft section 10 is back, so on the back of the snowboard boot 1 , at least partially formed so flexible that the lower leg 2 the carrier or the inner shoe shaft 15 of the liner 14 within a predetermined angular range, namely between the maximum front angular position W1 and the maximum rearward angular position W2, is substantially free to move from front to rear. The angle range in particular includes angles between 15 ° and 30 °, in particular between 20 ° and 25 °, preferably of approximately 23 °. The flexibility of the shaft section 10 For example, by a suitable structural design, in particular by suitable shaping, in particular an incision 13 , a partially reduced wall thickness of the shaft portion 10 or articulated elements, the use of soft, flexible, elastic or elastic materials or other constructive measures can be achieved. The shaft section 10 is not necessarily about its complete back height, so from the top of the heel section 11 up to the upper edge of the shaft 103 flexible, but could also only one area, preferably an area starting from the upper edge of the shaft 103 down, be flexible. As a result, the point shown here as the point of intersection of the three dash-dot lines, in particular the turning or tilting point, would become that of the lower leg 2 or the Liner shaft 15 relative to the shaft portion 10 is movable towards the rear, opposite the 1a and 1b move further upwards. The lower leg 2 could then be moved less far to the rear. The shaft section 10 can be provided, for example, with sewn-on or glued-on reinforcing elements which comprise, for example, textile materials, leather, plastic or fiber-reinforced materials, in particular carbon fibers, and in particular are water-repellent or waterproof.

In 1a is the lower leg 2 shown in a forwardly inclined position, which could also be referred to as a template position of the wearer. It is an imaginary center line of the lower leg 2 parallel to the dash-dot line, which marks the front angular position W1. The support strip 18 is here at the back of the shaft section 10 on, thus runs parallel to this substantially. The support strip 18 and the back of the shaft portion 10 are here with the inner shoe shank 15 and the lower leg enclosed by it 2 aligned in the front angular position W1.

In 1b is the lower leg 2 shown in a reclined position, which could also be referred to as a back position of the wearer. It is an imaginary center line of the lower leg 2 parallel to the dash-dot line, which marks the rear angular position W2. The support strip 18 is in the transition area between the heel section 11 and the shaft portion 10 at the shaft portion 10 movably fastened so that it moves, the movement of the lower leg 2 and the inner shoe shaft 15 following, back and forward again, move, in particular, can fold. The mobility to the front and back of the support strip 18 is indicated by a double arrow. The support strip 18 can, for example, by the use of stiffer materials than for the back of the shaft portion 10 or by appropriate reinforcing elements, be stiffened. This allows the support strip 18 as a movement limiting device 17 for the lower leg 2 or the inner shoe shaft 15 Act by the support strip 18 defines a maximum rear angular position W2, in which the wearer the lower leg 2 without significant effort, but not beyond. In particular, the support strip could 18 be resilient, so that with increasing movement of the lower leg 2 towards the rear, the resistance, in particular a spring restoring force increases.

In the 1a and 1b is an embodiment of the snowboard boot according to the invention 1 shown, in which the lower leg 2 relative to the back of the shaft portion 10 , in particular relative to the outer shell 22 , moves while the shaft section 10 even the movement essentially does not follow. However, embodiments are also conceivable in which the rear side of the shaft section 10 is designed so flexible that it is with the lower leg 2 or the inner shoe shaft 15 moved to the rear or front, for example by the use of stretchable, in particular elastic, materials on the back of the shaft portion 10 ,

2 shows an embodiment of the snowboard boot according to the invention 1 in a perspective rear view. The shaft section 10 has a V-shaped cut on the back, extending from the upper edge of the shaft 103 starting in the direction of the heel section 11 rejuvenated. The incision 13 separates a first lateral shaft section 101 from a second lateral shaft portion 102 that are on the outside or inside of the snowboard boot 1 are located. The lateral shaft sections 101 . 102 limit the incision 13 and run at its lower end, especially in the region of the upper end of the heel section 11 together and are preferably connected there. The incision 13 may have any shape, for example, U-shaped or rectangular and does not necessarily have to taper steadily downwards. The incision 13 could also be asymmetrical to a midplane of the snowboard boot 1 be designed or with an arbitrary about the height of the shaft portion 10 be formed changing width. There can be several cuts 13 at the back of the shaft section 10 be provided, but preferably only a single incision 13 , The incision 13 is in the stiff upper of the shaft portion 10 , especially in the outer shell 22 of the snowboard boot 1 , executed during the inner shoe shank 15 of the liner 14 not cut back according to the invention. The incision 13 is not necessarily designed to be open at the back, but could also, for example, by the use or sewing of an elastic material, be closed or clad, so that, for example, no snow through the incision 13 in the snowboard boots 1 can get. It would be conceivable both the inner shoe shank 15 as well as the shaft section 10 cut on the back, these cuts should not necessarily be the same or mutually corresponding. Preferably, as in FIG 2 shown, only the shaft portion 10 the outer shell 22 of the snowboard boot 1 an incision 13 on.

The snowboard boot 1 has a heel cap on the back 21 on, which is made for example of leather or plastic and over the heel section 11 extends or on this sewn or glued on. The heel cap 21 But it can also affect parts of the shaft section 10 expand. The heel cap 21 Tapered at its upper end, especially at an upper end of the heel section 11 , to a tab-like extension in the form of a strip, the support strip 18 forms. The support strip 18 can be made in one or more parts and is here in one piece with the heel counter 21 executed. The support strip 18 is on the back of the snowboard boot 1 movable on the heel section 11 and / or the shaft portion 10 attached, for example, sewn, glued or welded. The support strip 18 extends back along the shaft portion 10 up to the area of the upper edge of the shaft 103 , for example, to just below the upper edge of the shaft 100 , flush with the upper edge of the shaft 103 finally or over the upper edge of the shaft 103 protruding upward. The support strip 18 but could also be shorter, or completely missing.

When the lower leg 2 a carrier (not shown here) or the inner shoe shaft 15 moved backward, the first and second lateral shaft portions 101 . 102 laterally, ie in the direction of an outside or inside of the snowboard boot 1 , pressed apart or spread apart. The support strip 18 can be used as a movement limiting device 17 which defines a maximum rearward angular position W2, up to that of the innerboot shaft 15 through the incision 13 can be tilted backwards relative to the vertical V, as in 1b shown. Especially when running the snowboard boot 1 as a softboot, it can because of the incomplete rigidity of the outer shell 22 or the tongue section 12 , in particular by use of bending, stretchable and dustable materials, also to a deformation or tilting of the shaft portion 10 and / or the tongue section 12 come across the situation, this example in 1a ingest if the lower leg 2 or the inner shoe shaft 15 in a forward angular position W1.

The support strip 18 when it is moved forward or folded in a forward angular position W1, it conceals the incision 13 at least partially. This can help to prevent snow from entering the snowboard boot 1 prevented or restricted. The support strip 18 can be designed as a flat strip or as a, preferably about its longitudinal axis curved strip of different, in particular variable width. The support strip 18 could broaden upwards, and in particular to a form of incision 13 be coordinated. The lateral shaft sections 101 . 102 form on the back side a first shaft section rear surface 104 or a second shaft portion rear surface 105 out, which are flattened to the rear, leaving the support strip 18 in a front angular position W1 at least partially flat on the shaft portion 10 , in particular simultaneously the first and the second shaft portion rear surface 104 . 105 is applied. As a result, the stiffness, in particular torsional stiffness, of the snowboard boot 1 increased and this against the entry of snow through the incision 13 sealed. The support strip 18 is about a fixing device 16 (not shown here) on the shaft portion 10 attached fixable.

For the sake of clarity is in the 1a and 1b only the attachment loop 162 a fixing device 16 shown while in 2 in addition the belt 163 and the eyelet 161 are shown in dashed lines. A fixing device 16 and / or a movement limiting device 17 can in the embodiments of 1a . 1b and 2 but be provided.

In the figures 3a to 3c is an embodiment of the snowboard boot according to the invention 1 with a fixed support strip 18 shown in side views. In 3a and 3b is the outside of the snowboard boot 1 with the first shaft portion 101 shown while in 3c the inside of the snowboard boot 1 with the second shaft portion 102 is shown. In the upper part of the shaft section 10 is a fixing device 16 on the shaft section 10 appropriate. By the fixing device 16 is the shaft section 10 , in particular the inner shoe shank 15 or the lower leg 2 can be fixed in a front angular position W1. With a closed fixing device 16 The snowboard boot is in a driving mode while it is at an open fixing device 16 is located in a walking mode in which the lower leg 2 the carrier relative to the vertical 2 within a predetermined angular range, in particular between the front angular position W1 and the rear angular position W2, is substantially unhindered forward and backward movable.

The fixing device 16 is here with a belt 163 , For example, made of a solid or elastic material, which is connected via a fastening loop 162 displaceable on the shaft section 10 is attached. At one end of the belt 163 is an eyelet 161 fastened while the other end of it's strap 163 on the opposite lateral shaft portion 102 attached, in particular sewn, is. The belt 163 runs essentially transversely to the support strip 18 , seen from behind over the support strip 18 wherein the strap may be threaded through a guide loop. The belt 163 is behind the support strip 18 passed, so that when tightening or tensioning the belt 163 the support strip 18 in a front Angular position W1 is pulled, causing it on the shaft section 10 is applied. Here is the fixing device 16 via a Velcro strap, especially designed as a power strap 20 by the eyelet 161 threaded through and redirected to it, closed or opened. The Velcro strap 20 The runs on the front of the snowboard boot 1 across the tongue section 12 , It would also be conceivable, the belt 163 via a on a lateral shaft portion 101 . 102 fixed deflection as a separate Velcro strap perform. In this way, on the one hand, the tongue section 12 in the front area of the snowboard boot separately from the shaft portion 10 in the back of the snowboard boot 1 fixable. The fixing device 16 could also be considered a the shank section 10 be formed in the circumferential direction looping belt which forms a ring closure with itself. The fixing device 16 can also be implemented differently, in particular with a closure mechanism, which is based for example on a rotation, a snap, a displacement or insertion of a closure elements, and could in particular comprise a molded part, preferably made of plastic. For example, the fixing device 16 instead of a Velcro, a ratchet, a zipper or a lacing system include.

In 3a is the fixing device 16 closed or the belt 163 tightly dressed. As a result, the first and the second lateral shaft section become 101 . 102 held together or pressed together so that the incision 13 is narrowed, or at least can not be widened by the lateral shaft sections 101 . 102 by a movement of the lower leg 2 or the inner shoe shaft 15 be pushed backwards. In this way, the fixing device 16 a movement of the lower leg 2 block backwards. The snowboard boot 1 is in drive mode or departure mode.

In 3b is the fixing device 16 open. The support strip 18 is in a rear angular position W2. The snowboard boot 1 is in walking mode or ascent mode. The fixing device 16 Can also be used as a movement limiting device 17 act, the rear angular position W2, in particular from a wearer of the snowboard boot 1 adjustable while walking. The belt 163 Although it could be loosely fixed, but not tight, and thus on the back of the shaft section 10 a loop, in particular a belt loop form.

In 3c is the fixing device 16 closed, however, is the belt 163 not taut and forms a belt loop on the back, in which the support strip 18 is introduced from below. For a firm fixation of the ends of the belt 163 The size of the loop is set and defines a maximum rear angular position W2, up to that of the lower leg 2 or the inner shoe shaft 15 can move to the rear before the belt 163 , possibly also in cooperation with the support strip 18 , another movement blocked to the rear. About the Velcro strap 20 is the size of the belt loop and thus the maximum rear angular position W2 infinitely adjustable. The fixing device 16 may also be used in conjunction with other devices as a movement limiting device 17 interact. But it can also be a separate movement limiting device 17 be provided in particular alone by the support strip 18 blocking in a rear angular position W2 could be realized. Preferably, the fixing device 16 but uniform with the movement limiting device 17 executed. Here the belt takes over 163 both the function of the movement limitation and the fixation of the shaft portion 10 ,

The snowboard boot according to the invention 1 made possible by a rear flexible trained shank portion 10 a greater stride in the ascent and a more comfortable ascent without an uncomfortable strong pressure on the lower leg 2 of the carrier. By a fixing device 16 and a support strip 18 the stiffness of the snowboard boot1 is preserved for the downhill.

It should be noted at this point that all parts described above taken alone and in any combination, in particular the details shown in the drawings are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
