032147 B1

The invention relates to the field of sports, namely, ski bindings, and is intended for mounting ski boots with an axial mounting system for cross-country and other types of skis for all types of skiing, for sports, tourism, free skiing, telemark skiing, etc. .

Ski mounts are known according to US patent No. 4995632 (publ. 02.26.1991), comprising a body, a lock consisting of two parts (movable and fixed), a movable key, an axle, a shock absorber made of elastic material, a spring, a substrate.

The disadvantages of fastenings are the complexity of the design, high requirements for the accuracy of the manufacture of parts and the inconvenience of operation due to the need for great efforts on the governing body during forced opening.

Ski mounts are known according to the application of PCT AO 2012036561 (published on March 22, 2012), consisting of a body, a control key, a spring, a locking bracket with holes and a protrusion associated with the key, a bearing bracket, a lower plate and a shock absorber.

Ski mounts are also known according to the patent of the Russian Federation No. 2362603 (publ. 07.27.2009), containing a housing, a lock consisting of two parts - movable, in the form of a locking bracket with an axis and side vertical shelves, and fixed with vertical side shelves, a movable key, shock absorber made of elastic material, spring, lower curly plate.

The disadvantage of these fasteners is the complexity of the design, high weight, high requirements for strength characteristics and precision manufacturing of parts, the complex production technology of metal parts, the inconvenience of installation.

Ski mounts are known according to the patent of the Russian Federation No. 2382667 (publ. 02.27.2010), containing a cover, a transverse power element, a spring, a body on which a groove for hinging the ski boot is made, and a locking element is mated to the groove, which, by means of the the ability to rotate the control has the ability to move from the locked position, in which the boot is pivotally mounted in the mount, in the open position, ensuring the release of the boot.

The disadvantages of the fasteners is the presence of a cover for fixing the control element, which has an unreliable fastening, the complexity of the design of the locking mechanism, making high demands on the accuracy of manufacturing parts.

Ski mounts are known according to RF patent No. 2424841 (publ. 07.27.2011), comprising a housing, hook or engagement bracket installed in the housing with the possibility of longitudinal displacement and in the closed position made with the possibility of moving into the upwardly open inlet for the engaging element related to the sole and wherein the end of the engaging member opposite the engagement bracket is adapted to be connected via a connecting element to the drive element introduced from the upper side of the mount housing Ohm, first of all the drive lever.

The drawback of the fasteners is the design complexity, as well as insufficient reliability when there are sufficiently high loads when opening, closing and holding the boot axis, when the contact area of the trunnion section and the protrusion in the case may not be enough to absorb loads without deformation or destruction.

In addition, the disadvantage of all known ski bindings is that the control element (key or lever) is connected to the locking element and, when automatically locking, the elastic element, in addition to acting on the locking element, acts on the control element or on the mechanism connecting it to the locking element. As a result of this, additional loads on the elastic element arise, which lead to a decrease in the reliability of the automatic locking of the fastening and increased wear of the control element. Also, additional loads on the elastic element, leading to a decrease in the reliability of locking the fastening, can occur due to the impact on the control element of external factors (ice, dirt, casting defects, dents, cuts and other damage due to operation, etc.).

The technical result, to which the invention is directed, is to increase the reliability of the fastening by reducing the number of parts included in the fastening, by reducing the load during automatic locking on the locking element due to the lack of load on the locking element from the control element, and also due to the increased contact area the loaded surfaces of the control element and the housing, which are made in the form of at least one surface in the lower part of the control element, contact interacting with at least one surface facing it, made in the lower part of the front cavity of the mounting housing.

The technical result is achieved in a ski mount for securing a ski boot with an axis, comprising a body with an upward groove for the axis of the ski boot and open downward grooves made in the side walls, a locking element for securing the axis of the ski boot and a control element with a tabs on the side surfaces, configured to change its position. In this case, the control element is made with at least one protrusion in the lower part, and the casing with at least one surface on the lower part of the casing, facing at least one protrusion in the lower part of the control element.

The control element is fixed in the housing by means of protrusions on the side surfaces of the control element inserted into grooves in the side walls of the housing and pressed against the edges of these grooves due to at least one surface on the lower part of the housing pressed against at least one surface of the protrusion in the lower part of the control element .

In one embodiment, it is possible to execute at least one surface in the lower part of the control element in the form of the end surface of the stiffener.

Preferably, at least one protrusion at the bottom of the control is in the form of a stiffener.

Preferably, the control is formed with at least one stop in the form of a protrusion in the lower part.

Preferably, the control is in the form of a key or lever. Moreover, for the key of the control element, it is preferable to perform with a recess in the upper part for the tip of the ski stick.

In one embodiment, the mount comprises a spring, and the locking element has a protrusion in the front part, configured to interact with this spring. At the same time, a cavity is made in the housing for accommodating the spring with a protrusion for fixing it, and the locking element can be locked and / or in the open position by the spring and / or control element.

Preferably, the protrusion in the front of the locking element is configured to act on the stop in the form of a protrusion in the lower part of the control element.

Preferably, the mounting body contains an elastic element of elastic material (flexor) for interaction with the toe of the ski boot. In this case, the mounting housing is made with cavities on the inner side surfaces, and the elastic element is made with protrusions on the side surfaces, and is fixed in the housing due to the location of these protrusions in the specified cavities of the housing. For one embodiment, the protrusions are made in the side cavities of the housing, and the recesses are made on the protrusions of the elastic element, while the protrusions in the housing cavities are associated with the recesses on the protrusions of the elastic element.

In one embodiment, the mount contains a locking element that has a protrusion in the front part, configured to interact with an elastic element of elastic material (flexor), simultaneously designed to interact with the toe of the ski boot. In this case, the locking element may be in a closed and / or open position is fixed with a flexor and / or control element.

Preferably, the control is designed to be mounted in the housing from above. In this case, the mounting housing is made with the possibility of elastic deformation during installation of the control element.

Preferably, the housing is adapted to be secured to the ski with screws. In this case, it is preferable to perform a locking element with a through cutout or hole.

In one embodiment, the housing is made with a cavity in the lower part, in which, when the mount is mounted on the ski, a hook is made made on a bracket rigidly connected to the ski. It is preferable to make the bracket metal, and connect it to the ski using screws.

In another embodiment, the housing is made with lateral hooks with the possibility of mounting on a ski equipped with an additional device containing lateral protrusions or shelves intended for mounting.

In one embodiment, the locking element is made with side shelves with cutouts matching the axis of the ski boot. In this case, it is preferable to perform a locking element with inclined surfaces in the upper part of the side shelves.

It is preferable to make a case with inclined surfaces connecting with a groove for the axis of the ski boot, designed to guide the axis of the boot into the groove with automatic locking.

In one embodiment, the locking control element comprises at least two stops made in the form of protrusions in the lower part, the locking element being fixed when locked in the closed position by one of these protrusions, and the other protrusion is used to reverse the locking element during opening fastenings.

It is preferable to carry out a housing with a cavity and recesses in the rear part, with a plug placed in said cavity made with protrusions on the lower part fixed in said recesses of the rear part of the body.

It is preferable to perform protrusions on the side surfaces of the control element with beveled end surfaces or portions thereof.

When implementing the technical result, the load on the locking element, in the embodiment of the fastening with automatic locking using an elastic element (spring or flexor), is reduced due to the fact that the control element is not connected (rigidly or movably) to the locking element, but acts on the locking element the element only when the fastener is opened, thus reducing the load on the elastic element. This is achieved by the fact that the locking element has a protrusion in

- 2 032147 of the front part, on which, on the one hand, an elastic element acts, and on the opposite side, an emphasis in the form of a protrusion made in the lower part of the control element. Accordingly, when the locking element acts on the ski boot axis, the locking element moves, compressing the elastic element, and does not affect the control element, the protrusion of which is located on the opposite side of the protrusion of the locking element, and comes back, locking the ski boot axis with cutouts of the side flanges of the locking element moreover, the elastic element when locking elastically shifts only the locking element, while the control element remains stationary, which reduces the requirements for the magnitude of the force required for locking the axis of the boot with cutouts in the shelves of the locking element, and when the skier is forced to open the fastener by acting on the control element, the control element moves and acts on the protrusion of the locking element in the form of a stop made in its lower part, and overcoming the elastic resistance element, moves the locking element forward, freeing the axis of the ski boot.

In the claimed technical solution, a decrease in the number of attachment parts is achieved by the fact that the upper surface of the ski acts as the lower flat cover of the attachment mechanism, replacing it. If the attachment is attached to a ski equipped with an additional device, the upper surface of the device performs the function of the lower flat cover of the mechanism. For this, guides for the locking element, cutouts in the side walls and special surfaces in the lower part of the housing for mounting a control element with a possibility of movement in a structurally predetermined range, cavities with protrusions made in the middle part of the mount housing for fixing the elastic shock absorber for on its lateral surfaces there are protrusions with recesses, a special cavity in the front of the mount housing to accommodate, direct and limit the displacement of the spring. As a result, after mounting the ski mount, the upper surface of the ski or the device for mounting the mount performs the function of the bottom mount cover, restricting the movement of the spring (if available in the design), the locking element and holding the flexor (if available in the design) within the design limits, and the control the element is movably held by cuts in the side walls of the housing for the protrusions on the side surfaces and surfaces made in the lower part of the mounting housing in contact with the surfaces, made at the bottom of the control element. Thus, the bottom cover (plate, substrate) in the fastener structure becomes redundant, thereby reducing the number of fastener parts.

Also, a reduction in the number of fastening parts in comparison with analogues and an increase in reliability is achieved by the absence of additional parts (axles, rods, intermediate elements) in the design for attachment to the housing and the locking element of the control element or the action of the control element on them. The control element (key or lever) is movably held by protrusions formed on its lateral surfaces, which engage with corresponding cutouts in the front cavity of the attachment housing and the lower surfaces of the ribs of the control element (key or lever), which interact with their corresponding surfaces in the lower part the front cavity of the mounting body, which may have a sufficiently large contact area to counter the compressive force of the elastic element (spring or flexor) or the force for holding the locking element in the open state and reducing wear when the control element moves under load from the elastic element and / or locking element. During installation, the control element (button or lever) elastically snaps into the cutouts in the walls of the front cavity of the housing. Moreover, the installation of the control element (button or lever) can be made both before installing the mounting housing on the ski or a special device, and later, depending on the applied design.

Also, the control element (key or lever) acts by the emphasis in the form of a protrusion made in the lower part of the control element directly on the protrusion made on the locking element. Thus, the design does not use parts for attaching the control element to the housing and the locking element (axles, brackets, rods, intermediate elements and others) or for transmitting interaction between them.

In the side walls of the cavity (17) there are grooves (19), which mesh with the side protrusions (18) located on the key (3) or lever (4). Curved or cylindrical surfaces (21) are located in the lower part of the cavity (17) of the housing (1), corresponding to the surfaces (39) on the lower stiffening ribs (20) of the key (3) or lever (4). The engagement of the side protrusions (18) of the key (3) or the lever (4) with the grooves (19) in the side walls of the cavity (17) of the housing (1) of the mount and (possibly) the interaction of the surfaces (21) in the lower part of the cavity (17) of the housing ( 1) fastening with the lower surfaces of the ribs (20) of the key (3) or lever (4) ensures that the key (3) or lever (4) is held with the possibility of changing position (rotation) in a structurally specified range. In the front part of the cavity (17) of the attachment housing (1), a cavity (23) can be formed to accommodate and guide the spring (8) acting on the protrusion (7) of the locking element (5), possibly with protrusions for holding the spring (8). Also, a hole (40) can be made in the lower part of the front cavity (17) of the housing (1) to fix the housing (1) on the ski (11) by means of a screw (10). In the middle part of the attachment body (1) there are cavities (37) with protrusions (41) for fixing the elastic element (6), allowing it to undergo elastic deformations when exposed to the surface of the toe of the boot of the skier.

In the middle part of the housing (1) there is a groove (27) for the axis (9) of the ski boot. The inclined surfaces (42) of the housing (1) are connected to the groove (27). Also in the middle part of the housing (1) there are cutouts (43) to accommodate the shelves (25) of the locking element (5). The dimensions of the cutouts (43) are made in such a way that the locking element (5) can make a working stroke and lock, or release the axis (9) of the ski boot. The tail part (2) of the housing (1) is a guide of complex shape with one or two longitudinal guides (38) depending on the compatible type of ski boot sole used, with holes (44) for screws (10) (holes can be made (44 ) an elongated shape to compensate for the difference in the linear dimensions of the ski (11) and the mounting body (1) during their deformation). Also, in the tail part (2) of the housing (1), it is possible to carry out a cavity (32) for one or more plugs (16) for hiding and protecting screws (10) as well as performing a decorative function. Also, in the lower part of the mounting body (1), a cavity (36) can be made for the hook (35) of the bracket (12) mounted on the ski (11) by means of screws (13). In the case of attaching the mounting housing (1) to the device (14) mounted on the ski (11) on the lower lower surfaces of the housing (1), longitudinal hooks (15) can be made, which engage in the cutouts (37) of the device (14) , as well as on the housing (1), locking and centering elements (protrusions and surfaces) (45; 46) can be made, interacting with the corresponding elements (protrusions and surfaces) (47; 48) on the fixture (14) for fixing the mounting case ( 1) relative to the device (14). In an embodiment of the housing (1) with a control element made in the form of a key (3) in the walls of the front cavity (17), cut-outs (49) can be made for the convenience of pressing the key (3).

The control element (movable key (3) or lever (4)) is a part, preferably made of plastic. On the side surfaces of the key (3) or lever (4), lateral protrusions (18) are made, which engage with grooves (19) in the side walls of the front cavity (17) of the mounting body (1). In the lower part of the key (3) or lever (4), stiffeners (20) are located, which may have a lower surface (39) corresponding to the surfaces (21) in the lower part of the cavity (17) of the housing (1). The ribs (20) are joined by a transverse stop (22), the end of which acts on the protrusion (7) of the movable locking bracket (5) for forcibly opening (opening) the fastening. On the upper surface of the key (3), a reinforced receiving recess (50) can be made for a pressing object (for example, the tip of a ski pole). In front of the lever (4), surfaces (51) can be made for interacting with the hand of the skier. To fix the control element (lever (4)) in the open position in the lower part of the lever (4) on the ribs (20) there may be protrusions (52), which are in elastic engagement with the corresponding protrusions (53) in the lower part of the front cavity (17 ) housing (1) mounts.

The locking element (5) is preferably made of metal by stamping (it is preferably subjected to heat treatment (for example, hardened) to obtain the desired strength properties and is coated with a protective coating). The locking element (5) is made as a single bracket with vertical side shelves (25) and made in them curly cutouts (26) to hold the axis (9) of the ski boot and inclined surfaces (54) in the upper part of the shelves (25) for the shift of the locking element (5) and overcoming the compression force of the spring (8) or the elastic element (6) when exposed to the axis (9) of the boot to trigger fastening with automatic closure. In the front part of the locking element (5), a protrusion (7) is made, which is located at a structurally predetermined angle (preferably 80 °), on which, on the one hand, the stop (22) made in the key (3) or lever acts (upon forced opening of the mount) (4), and from the outside - a spring (8), or an elastic element (6), or an additional stop (24) that hold the locking element (5) in a closed

- 6 032147 condition for holding the axis (9) of the ski boot. In the middle part of the locking element (5), an opening (28) can be made to accommodate the seat of the screw (10) in the variant of attaching the mount to the ski (11) using screws (10), having a size sufficient to move the locking element (5) at his working course. In the embodiment of the attachment, when attaching to the ski (11) to the accessory (14) by means of side hooks (15) or by attaching the head of the housing (1) with two screws (10), the hole (28) may be absent.

The elastic element (6) is preferably made of an elastic thermoplastic material or rubber. In the front part, on the side surfaces of the elastic element (6), protrusions (31) are made with recesses (30), with the help of which it is held in the cavities (37) of the housing (1). In the internal cavity of the elastic element (6), one or more ribs (55) can be made, which give the specified rigidity during deformation of the elastic element (6). On the outer surface of the elastic element (6) there are guide cutouts (56), which serve as guides for a given deformation during compression of the elastic element (6) with the toe of the ski boot. The surface (57) of the elastic element (6), designed to interact with the toe of the ski boot, may have a different shape depending on the type of boot used. Also, the elastic element (6) can act on the front protrusion (7) of the locking element (5) in the embodiment of the fastening with automatic locking.

The hook (35) is made in such a way that when the mount is installed, it enters the cavity (36) made in the mount housing (1).

The mount can be mounted on a ski (11) in pre-drilled holes (59) according to a geometrically defined pattern corresponding to the mounting holes of the mount, to prevent moisture penetration and loosening the screws, the holes can be pre-filled with an adhesive (sealing) compound. With screws (13), a bracket (12) is attached to the ski (11). A housing (1) is mounted on a fixed bracket (12) with an elastic element (6) pre-installed in it (if it is provided for by the structure), a locking bracket (5) and possibly a spring (8), so that the hook (35) of the bracket ( 12) enters the cavity (36) of the attachment case (1) and then the case is fixed to the ski (11) with screws (10) through the holes (40, 44) in the front cavity (17) and the tail part (2) of the case (1). Then, a control element (button (3) or lever (4)) is installed (elastically latched) into the grooves (19) in the front cavity (17) of the housing (1). Moreover, the installation can occur both by simultaneous and sequential introduction of the protrusions (18) made on the control element (2; 3) into the grooves (19) of the walls of the housing (1) during its elastic deformation, then into the cavity (32) in the back of the housing (1), the decorative plug (16) is elastically latched, if this is provided by the design. If there is no screw (10) and hole (40) in the front cavity (17), the control element (button (3) or lever (4)) can be installed in advance.

When mounting the ski mount using the screws (10) without the supporting bracket (12), the mount is mounted on the ski using the screws (10) into the pre-drilled holes (59) in the ski (11) according to the geometry defined in the geometrical dimensions corresponding to the mounting holes of the mount, to prevent the penetration of moisture and loosen the screws (10), the holes (59) can be filled with an adhesive (sealing) composition. With screws (10), the fastening body (1) is attached to the ski with the locking element (5) pre-installed in it and if their presence is provided for by the structure, the elastic element (6) and the spring (8). Then, a control element (button (3) or lever (4)) is installed (elastically latched) into the grooves (19) of the front cavity (17) of the housing (1) and, possibly, a decorative cap (16) is elastically latched into the cavity (32) of the rear part of the housing . If the presence of a screw (10) in the front cavity (17) is not provided, then the control element (button (3) or lever (4)) can be installed in advance.

Mounting works as follows.

To close the mounting option containing a control element made in the form of a key (3) and an elastic element (spring (8) or flexor (6)), the ski boot axis (9) when a skier applies force (pressure with his toe down) enters between inclined surfaces (54) shelves (25) of the locking element (5) and the inclined surfaces (42) made in the housing (1) of the mount, and moves the locking element (5), overcoming the resistance of the elastic element (spring (8) or flexor (6)) . As soon as the axis (9) is in the groove (27), the locking element (5) returns under the action of the elastic element (spring (8) or flexor (6)) to the protrusion (7) and locks the axis (9) of the boot into the groove (27) ) by the surfaces of curly cuts (26). Thus, the axis (9) of the boot is held at negative vertical loads by the locking element (5), and with positive vertical and alternating signs in the vertical plane, by the locking element (5) and the mounting body (1). Moreover, in the embodiment of the fastening with the bracket (12), the loads from the housing (1) and the locking element (5) are transferred to the bracket (12). The surface of the figured cutouts (26), facing the groove (27), can have an angle of inclination to the horizontal plane, choosing the gap between the axis (9) of the boot and the groove (27). Thus, the connection in the closed state can be without a gap. In the closed state, the locking element (5) is affected by the compression force of the elastic element (spring (8) or flexor (6)), which prevents the fastener from being opened. In this case, when the fastening for the circuit is automatically activated, the load from the protrusion (7) of the locking element (5) is not transferred to the key (3) or lever (4), i.e. they remain stationary and do not create additional resistance to the spring (8) or flexor (6).

The closure of the mounting option containing the control element, made in the form of a lever (4), and the elastic element (spring (8) or flexor (6)) can be performed in two ways. The first closure method is similar to the version with the key (3) (automatic locking). And the second method is carried out by influencing the skier on the lever (4) with his hand behind the surface (51) by turning it up, which opens the mount, and when the lever (4) is turned, its emphasis (22) moves the locking element (5) and, accordingly, the protrusion (7) ) compresses the elastic element (spring (8) or flexor (6)). In this case, the lever (4) is fixed in the open position by a latch or by the friction forces of the protrusion (7) of the locking element (5) and the protrusion (22) of the lever (4). The groove (27) is released due to the shift of the locking element (5) and the axis (9) of the boot can be freely installed in the groove (27). Then the lever (4) returns with the skier’s hand to its original position, and the spring force (8) or flexor (6) returns the locking element (5) to its original position and the axis (9) is closed in the groove (27) by the surfaces of the figured cutouts (26) ) shelves (25) of the locking element (5). Thus, a controlled locking of the fasteners and the possibility of fixing in the open state are achieved, which is necessary when used as children's fasteners as additional safety measures.

When mounting in the version with a lever (4) having an additional stop (24), turning the lever (4) from the open to the closed position, the skier closes the mount, and when the lever (4) is turned, its additional stop (24) puts pressure on the stop ( 7) the locking element (5), shifting it and fixing the axis (9) in the groove (27) by the surfaces of the figured cutouts (26) of the shelves (25). In this case, the lever (4) is fixed in the closed position by a latch or by friction.

To open the mounting option containing a control element made in the form of a key (3) or a lever (4) and an elastic element (spring (8) or flexor (6)), the skier acts on the key (3), for example, with a ski pole or with his hand or acts on the lever (4) by hand. At the same time, the key (3) or the lever (4) rotates relative to the axis formed by the grooves (19) in the front cavity (17) of the mount body (1) and the surface (21) in the lower part of the front cavity (17) of the mount body (1), interacting with the grooves (19) by the protrusions (18) on the lateral surfaces of the control element (key (3) or lever (4)) and the lower surfaces (39) of the ribs (20) with the lower surface (21) of the front cavity (17) of the attachment body ( 1) and act as a stop in the form of a protrusion (22) on the protrusion (7) of the locking element (5), overcoming the resistance of the elastic element (spring (8) or flexor (6)). As a result, the locking element (5) moves, freeing the axis (9) of the ski boot, located in the groove (27), from locking curly cutouts (26). Moreover, in the embodiment of the control element in the form of a key (3), it is necessary to keep the key (3) pressed until the axis (9) is removed from the groove (27), and in the embodiment of the control element in the form of a lever (4), it is fixed without application of force by the skier as a result of the action of friction forces or special latches.

When performing fastening without an elastic element (7; 8) in the version with mechanical locking, with a lever (4) having an additional stop (24), to open the skier acts on the lever (4) by hand, and when the lever (4) is turned, the stop ( 22) puts pressure on the protrusion (7) of the locking element (5), shifting it and accordingly releasing the axis (9) from the groove (27). In this case, the lever (4) can be fixed in the open position by a latch or by friction.

During movement, the shoe rotates together with the axis (9) in the groove (27), compressing the elastic element (6), which exerts the necessary back pressure on the toe of the shoe with the surface (57) (when using the design scheme with the action of the elastic element (6) on the surface ski boot toe). The loads from the ski boot are transferred to the ski (11) through the axis (9) in the nose of the ski boot, fixed in the groove (27) of the housing (1) by the surfaces of the figured cutouts (26) of the locking element

- 8 032147 that (5) and the sole of the ski boot, interacting with the tail part (2) of the housing (1) of the ski mount. In the embodiment of fastening with fastening on the ski (11) with a bracket (12) and screws (10), the loads are transferred to the ski (11) through the bracket (12), the locking element (5), the body (1) of the mount and the screws (10; 13). In the embodiment of the fastening with fastening to the ski (11) only by the screws (10), the loads are transferred to the ski (11) through the locking element (5), the fastening body (1) and the screws (10). In the embodiment of the fastening with fastening by means of side hooks (15) to a special device (14) mounted on the ski (11) with an additional device (14), the loads are transmitted through the locking element (5) and the fastening case (1). Also, longitudinal cutouts made on the sole of the ski boot are engaged with the corresponding guides (protrusions) (38) in the tail part (2) of the housing (1) and as a result, the housing (1) takes up vertical and lateral loads from the sole of the ski boot with the horizontal location of the boot and transfers them to the ski (11) or device (14).

Thus, a technical result is achieved. Since the key (3) or lever (4) only accepts loads during the opening of the fastening, they can be made of less durable plastic without reinforcing fillers, which also simplifies the production technology and increases the tooling life. Due to the reduction of efforts on the elastic element (6; 8), increased reliability of locking the fastening is achieved if there is ice, snow or dirt in the fastening, which makes it possible to use fasteners on unprepared tracks, under adverse conditions and expands the scope of their application. The possibility of using the lever (4) as a control element creates the possibility of additional control and operational safety, which allows the use of the mount for children and adolescents, expanding the scope of application of the mount.
