[0002] Visor mechanism for a protective helmet with a swiveling and sliding visor

[0003] The present invention relates to a visor mechanism for a protective helmet, such as is intended particularly for emergency services personnel, and as defined in the preamble of claim 1. The invention further relates to a protective helmet, such as is intended particularly for emergency services personnel, and to a method for moving a visor to cover a front area of ​​a protective helmet, particularly for emergency services personnel, between a visor-in-use position and a visor-out-of-use position.

[0004] Protective helmets, especially those used by the military, police, or other emergency services, primarily serve to protect the wearer from mechanical injuries. In addition to the standard outer shell for distributing impact forces, such helmets typically feature a visor that can be lowered to protect the face, covering the front of the helmet and shielding the wearer from blows to the face or thrown objects.

[0005] It is known from the prior art to offer such visors either integrated into a protective helmet from the outset or as a retrofittable device for protective helmets. It is advantageous to be able to move the visor between a visor-use position, in which the visor protects the helmet wearer in the front area of ​​the protective helmet, and a visor-non-use position, in which the visor is removed from the front area and regularly positioned upwards towards the upper front area, in order to allow emergency personnel to react flexibly to the operational conditions.

[0006] To selectively move the visor between the visor's operational and non-operational positions, it is known to provide an adjustment mechanism. Such a visor mechanism for performing the adjustment movement should, on the one hand, allow the visor to be reliably and quickly moved into the desired position, and on the other hand, prevent the helmet wearer from having to perform overly complex adjustment movements or even [SBT-01 / 25-PCT 2 19.02.2026].

[0007] Adjustments to the protective helmet may be necessary. In principle, the adjustment should be easy for the helmet wearer to perform, which is particularly important in operational situations.

[0008] The applicant has proposed a visor mechanism for a protective helmet in WO 2021 / 048281 Al, from which the present invention is based. The need for optimization lies in the fact that the known visor mechanism requires a relatively large area for the fixed mounting of the visor mechanism on the outer shell of the protective helmet, and thus the helmet is generally covered to a considerable extent. Therefore, it is desirable that the visor mechanism itself, as well as the adjustment of the visor, impair the functionality of the protective helmet with regard to the installation and operation of other external functional units, in particular a night vision device.

[0009] Furthermore, it is desirable that a visor mechanism that is as general as possible is provided universally for different protective helmets, be they types of protective helmets but especially also sizes of protective helmets, so that the overall manufacturing effort for protective helmets with corresponding visor mechanisms can be reduced.

[0010] Based on this prior art, the object of the invention is therefore to further develop and improve the visor mechanism for a protective helmet known from the prior art, as well as a method for repositioning a visor, so that the visor can be repositioned between positions as easily and reliably as possible, without this having to compromise other functional units of the protective helmet. In particular, the manufacturing effort for protective helmets with visor mechanisms should be kept as low as possible, even for different helmet sizes.

[0011] This problem is solved for a visor mechanism with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. With regard to a protective helmet, the problem is solved by a protective helmet with the features of claim 14. With regard to a method for positioning a visor with the features of the preamble of claim 15, SBT-01 / 25-PCT 3 19.02.2026

[0012] The problem is solved by the features of the characterizing part of claim 15. Advantageous embodiments of the visor mechanism, the protective helmet, and the method are the subject of the dependent claims and the following description.

[0013] The key finding here is that the adjustment movement of the visor is not simply performed in a single motion, which inevitably leads to a greater restriction of the visor's movement path during adjustment, but rather that the adjustment movement is divided into two distinct motion types. This approach achieves greater flexibility regarding the movement paths of the adjustable visor. The adjustment movement, ultimately divided into two motion types and thus fundamentally different movement paths, can then be designed to minimize or even completely avoid collisions with functional components of the protective helmet, which are often located on its outer shell.

[0014] On the other hand, the adjustment mechanism can be configured as efficiently as possible so that the helmet wearer can move the visor between the two positions with one hand without having to move their hand too far away from the helmet. By accepting the perceived disadvantage of a more complex adjustment mechanism, a greater range of motion is gained. An adjustment that can be performed with one hand can also be achieved.

[0015] The proposed visor mechanism is for a protective helmet, which may in particular be a protective helmet for emergency personnel. The proposed visor mechanism includes a carrier for a visor to cover a front area of ​​the protective helmet. The front area of ​​the protective helmet is understood to be the open front area, which corresponds to the face area and, in particular, the eye area of ​​a wearer of the protective helmet. The carrier of the proposed visor mechanism can either be connected to a visor, for example, detachably, by inserting a visor into the carrier or otherwise receiving it within it, or the carrier can be provided without a visor and configured to receive a visor to be added and connected. Furthermore, it is conceivable that the carrier and the visor are formed as a single unit, i.e., the carrier is integrated into the visor. SBT-01 / 25-PCT 4 19.02.2026

[0016] is integrated and, for example, is a one-piece molding onto the visor.

[0017] For example, the support part could also be a thickening, provided with bores, which bores may also have sliding sleeves or the like, and via which bores or sliding sleeves the support part or in this case the sight itself is arranged to be movable.

[0018] The support element of the proposed visor mechanism is designed to be movable between a visor-in-use position and a visor-out-of-use position by means of an adjustment movement acting on the support element or on the visor. In particular, the adjustment movement can be performed manually by the helmet wearer, and especially with one hand.

[0019] The proposed sighting mechanism is characterized by the fact that the adjustment movement is divided into two different types of movement.

[0020] The visor's operating position is such that, when mounted on the helmet, the visor is positioned in the front area of ​​the helmet and, preferably, extends to an area below a front edge of the helmet. The visor's non-operating position is such that, when mounted on the helmet, the visor and / or the support element, preferably the entire visor mechanism, is positioned above the front area of ​​the helmet and, preferably, the visor and / or the support element, preferably the entire visor mechanism, is positioned entirely above a front edge of the helmet, and, preferably, the visor and / or the support element, preferably the entire visor mechanism, is positioned below a horizontal plane defined by the apex of the helmet. The visor or...The entire visor mechanism advantageously interferes with the helmet wearer as little as possible in the visor-not-used position and also protrudes as little as possible from the protective helmet to the outside.

[0021] The protective helmet proposed according to a further independent aspect of the invention is intended in particular for emergency services and is marked SBT-01 / 25-PCT 5 19.02.2026

[0022] by a proposed sighting mechanism as described above or below or in any one of claims 1 to 12.

[0023] The support element may be made of or consist of plastic. The support element may, in particular, have one or more guide bores by which it is slidably arranged along a sliding guide, such as one or two brackets. The support element may include a visor mounting unit for receiving and connecting to a visor, as well as a sliding section for guidance along the sliding guide or bracket(s).

[0024] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, a first type of movement of the two differing types of movement may include pivoting the support part or the visor about an axis of rotation. In particular, the corresponding adjustment movement according to this first type of movement may be a pivoting of the support part or the visor that essentially follows a circular path.

[0025] Furthermore, the proposed visor mechanism or protective helmet may be designed so that the axis of rotation, particularly when viewed in the visor's operational position, is located above the support structure and / or set back from it. Such an arrangement of the axis of rotation makes it possible to store the visor, especially in the non-operational position, in such a way that it minimally interferes with the use of the protective helmet without the visor.

[0026] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, it can be provided that a second type of movement of the two differing types of movement includes a displacement of the support part or the visor.

[0027] In particular, it may be provided that the carrier part or the visor can be moved along a sliding guide, especially in the form of one or two brackets. SBT-01 / 25-PCT 6 19.02.2026

[0028] Furthermore, the proposed visor mechanism or the proposed protective helmet may include provisions for shifting the second type of movement:

[0029] a shift upwards, particularly when viewed from the sight's operational position, and / or a shift downwards, particularly when viewed from the sight's non-operational position;

[0030] and / or

[0031] a displacement along a curved path, especially when viewed from the visor's operating position back towards the protective helmet.

[0032] Sliding the visor along a curved path is particularly advantageous, especially if the path of the visor mirrors the shape of the helmet's outer shell. This results in minimal bulk from the visor mechanism and allows for space-saving storage of the visor when not in use.

[0033] The terms "first type of movement" and "second type of movement," and consequently the examples given for them, should not necessarily be understood as a sequence or as meaning that the second type of movement could not exist without the first. Rather, the proposal envisions two distinct types of movement, which inevitably leads to a first and a second type of movement.

[0034] In an embodiment combining a pivoting and a sliding movement of the support part or the visor, it can advantageously be achieved that the visor can first be pivoted away from the protective helmet (both from the visor's operational position and from the visor's non-operational position) in order to achieve a collision-free sliding plane in which the visor can then be safely moved (to bring the visor towards the other position). SBT-01 / 25-PCT 7 19.02.2026

[0035] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, it can be provided that a component of the visor mechanism providing the adjustment movement, in particular a sliding guide leading to the displacement of the carrier part, is rotatable about an axis of rotation in order to realize the pivoting of the carrier part about the axis of rotation.

[0036] Preferably, the visor mechanism comprises a helmet attachment unit for connection to the protective helmet, preferably detachable, and a displacement section connected to the helmet attachment unit and, in particular, adjoining the helmet attachment unit at the top. The displacement guide is articulated to the displacement section, in particular by means of a plug-in axle providing the axis of rotation, and is thus rotatable relative to the displacement section. In a state of the visor mechanism mounted on the protective helmet, the displacement guide is rotatable, in particular, relative to the protective helmet, especially the outer shell of the protective helmet.In the sight-in-use position, the support element is arranged, in particular, at the top of the sliding guide and so close to the axis of rotation that when the support element pivots from the sight-in-use position, especially to a first intermediate position or vice versa, following a path that is essentially circular, the circular path has a comparatively small radius. In the sight-in-use position, however, the support element is arranged, in particular, at the bottom of the sliding guide and so far from the axis of rotation that when the support element pivots from the sight-in-use position, especially to a second intermediate position or vice versa, following a path that is essentially circular, the circular path has a comparatively large radius.

[0037] In particular, the radius of the circular path when pivoting from or into the visor's operating position is at least twice as large, preferably at least three times as large, as the radius of the circular path when pivoting from or into the visor's non-operating position. The support element is displaceable along the sliding guide, particularly from the first intermediate position to the second intermediate position and vice versa. The sliding guide is preferably rotatable for movement into a position spaced apart from the helmet attachment unit. SBT-01 / 25-PCT 8 19.02.2026

[0038] In a preferred embodiment of the proposed visor mechanism or protective helmet, the support element for the visor can be positioned below a component of the visor mechanism that provides the adjustment movement, in particular below a sliding guide that directs the movement of the support element, preferably in the form of a bracket or two brackets. In this way, the movement of the visor advantageously avoids any risk of collision with components located above the sliding guide or the bracket(s), such as external functional units, e.g., a night vision device. Advantageously, such external functional units can simply remain mounted on the protective helmet, or in this case, on the visor mechanism, the sliding guide, or the bracket(s), while the adjustment movement of the support element or the visor takes place.

[0039] According to a preferred embodiment of the proposed visor mechanism or protective helmet, contact surfaces in a contact area between the carrier part and a component of the visor mechanism that provides the adjustment movement, in particular a sliding guide that guides the movement of the carrier part, preferably in the form of one or two brackets, may form a material pairing designed for improved sliding, wherein the materials of the contact surfaces in the contact area are different. The materials may be matched to form a good sliding pair. For example, the carrier part or its sliding section, or at least the inner surfaces of corresponding guide bores, may be made of polycarbonate (PC), while the sliding guide, the brackets, or at least their outer surfaces may be made of polyoxymethylene (POM).This specific material pairing enables low-friction movement of the carrier component along the sliding guide, resulting in improved operability of the sighting mechanism. The use of sliding sleeves to provide improved guidance is also conceivable.

[0040] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, a top-mounted visor mechanism device carrier can be used for connecting external functional units, SBT-01 / 25-PCT 9 19.02.2026

[0041] in particular a night vision device. Preferably, the upper visor mechanism support can provide the connection above one of the components of the visor mechanism that provides the adjustment movement, in particular above a sliding guide that guides the movement of the support part, preferably in the form of a bracket or two brackets. This makes it particularly advantageous to be able to change the visor between the operational and non-operational positions without having to remove external functional units, such as a night vision device, from the helmet. In a state mounted on the helmet, the upper visor mechanism support is therefore not fixed in place, but rather movable, as it can be pivoted away from the helmet. The sliding guide or...The bracket(s) are preferably arranged to be rotatable relative to the protective helmet, in particular the outer shell of the protective helmet, as described above when mounted.

[0042] According to a preferred embodiment of the proposed visor mechanism or protective helmet, a spring arrangement can be provided to exert a spring force acting on the support element, preferably indirectly, and thus on the visor, preferably indirectly, preferably pointing towards an outer shell of the protective helmet. This advantageously ensures secure positioning of the visor in the corresponding end positions, i.e., in the visor-in-use position and in the visor-out-of-use position, by forcing the visor towards the front area or towards the outer shell. This prevents the visor from shifting during use or in the out-of-use position. The position of the visor is thus stabilized, which is particularly important when the protective helmet is used in dynamic environments, as is often the case with emergency services.The spring arrangement helps to ensure that the visor rests securely against the outer shell of the protective helmet when not in use, which improves aerodynamics and minimizes the risk of damage or unintentional adjustment of the visor. Preferably, the spring force serves to counteract the pivoting of the support element around the axis of rotation in a visor displacement direction (in particular upwards away from the protective helmet or forwards away from the front area) and to assist the pivoting of the SBT-01 / 25-PCT 10 19.02.2026.

[0043] The support element rotates around the axis of rotation in the opposite direction of visor displacement (in particular downwards towards the helmet or back towards the front area). The spring assembly can, in particular, include a torsion spring. The spring force can act against the outward rotational movement according to the first type of movement, i.e., against a pivoting upwards away from the helmet or forwards away from the front area.

[0044] According to a preferred embodiment of the proposed visor mechanism or protective helmet, the support part can be provided, in particular via a visor mounting unit, for a preferably detachable connection with a visor, especially for a positive-locking and / or force-locking connection of the visor. Furthermore, the visor mounting unit can preferably be designed for detachable connection with different visors of varying widths. Alternatively or additionally, a visor for the protection of the helmet wearer can be detachably connected to the support part, in particular by being clamped into a visor mounting unit. The proposed visor mechanism thus enables a standardized component concept, since the same visor mechanism can be used to mount different types and, above all, widths of visors, for example, for different helmet types and, most importantly, helmet sizes.

[0045] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, the support element can be positioned to move between the visor-in-use and visor-out-of-use positions by direct actuation of the support element or the visor itself. In particular, actuation or manual manipulation of either the support element or the visor itself can adjust the visor. Such direct actuation of the visor thus constitutes a manual intervention by the wearer of the protective helmet. Preferably, the visor is adjustable by direct actuation of the visor. For this purpose, the helmet wearer must, for example, first pivot the visor to move it, and then pivot it back again (which SBT-01 / 25-PCT 11 19.02.2026).

[0046] The return to the starting position can also be done automatically or with the assistance of the spring arrangement).

[0047] According to a preferred embodiment of the proposed protective helmet, the visor mechanism can be mounted on the outside of the outer shell of the protective helmet, preferably being connected, in particular via a helmet attachment unit, to a front device carrier (shroud) of the protective helmet, preferably detachably.

[0048] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, it can be provided that in the visor-in-use position and / or in the visor-out-of-use position, only one of the two types of movement is possible, while the other is blocked. In particular, only the pivoting of the support part or the visor is possible, while the sliding movement, preferably via a positive locking of the movable part of the visor mechanism with the protective helmet, is blocked. In other words, sliding the support part or the visor is then only possible if the support part or the visor is pivoted at least slightly forward or upward from the visor-in-use position and / or the visor-out-of-use position, in particular into the first intermediate position or the second intermediate position.Greater safety is achieved in maintaining the two intended end positions in the form of the sight-in-use position and the sight-out-of-use position.

[0049] According to a preferred embodiment of the proposed visor mechanism or the proposed protective helmet, the sliding guide can be arranged substantially centrally with respect to a longitudinal section through the protective helmet, in particular that two brackets each have a substantially equal lateral distance to a longitudinal section running longitudinally and centrally through the protective helmet. The axis of rotation about which the sliding guide is preferably rotatable is preferably aligned orthogonally to the longitudinal section. SBT-01 / 25-PCT 12 19.02.2026

[0050] Preferably, the visor mechanism is provided separately and can therefore be mounted on a protective helmet. In particular, it may be possible to retrofit the visor mechanism to a protective helmet that was not originally designed for such mounting. However, it is also possible that the visor mechanism is an integral and original component of a protective helmet.

[0051] The method proposed according to a further independent aspect of the invention for moving a visor covering a front area of ​​a protective helmet, particularly for emergency personnel, between a visor-use position and a visor-non-use position is particularly applicable to a protective helmet as described above, below, or in claim 13. The proposed method is characterized in that a support element for the visor is moved between the visor-use position and the visor-non-use position by means of an adjustment movement which is divided into two different types of movement.

[0052] According to a preferred embodiment of the proposed method, the two differing types of movement may include pivoting the support part about an axis of rotation and / or displacing the support part. Preferably, the following may also apply:

[0053] The axis of rotation, particularly when viewed in the sight-use position, is located above the support part and / or set back from the support part;

[0054] and / or

[0055] the shift occurs upwards, particularly when viewed from the sight's operational position, and / or the shift occurs downwards, particularly when viewed from the sight's non-operational position;

[0056] and / or

[0057] The shift occurs along a curved path, particularly when viewed from the visor's operating position, pointing back towards the helmet. SBT-01 / 25-PCT 13 19.02.2026

[0058] According to a preferred embodiment of the proposed method, one of the two differing types of movement, in particular the pivoting of the support part about the axis of rotation, is carried out in a visor displacement direction against a spring force exerted by a spring arrangement, preferably in the direction of an outer shell of the protective helmet. In particular, this one of the two differing types of movement, in particular the pivoting of the support part about the axis of rotation, is carried out in the other, opposite visor displacement direction by the spring force exerted by the spring arrangement, preferably in the direction of the outer shell of the protective helmet.

[0059] In a preferred embodiment of the proposed method, it can be provided that the support element is first pivoted and then slid to move it from the visor-used position to the visor-not-used position. Preferably, in a first step, the support element is moved from the visor-used position to the second intermediate position by pivoting, in which the support element, particularly the first intermediate position, is slidable. The sliding guide is, in particular, rotated to a position spaced away from the helmet attachment unit. Preferably, it is further provided that in a second step the support element is slid from the second intermediate position to the first intermediate position and then, in a third step, pivoted from the first intermediate position to the visor-not-used position.

[0060] In particular, it is further preferably provided that first a pivoting movement of the carrier part and then a sliding movement of the carrier part is carried out in order to move the carrier part from the sight-non-use position to the sight-use position.

[0061] Preferably, in a first step, the support element is moved from the visor-in-use position to the first intermediate position by pivoting or pivoting it, in which the support element is slidable, particularly into a second intermediate position. The sliding guide is specifically designed to be positioned at a distance from the helmet attachment unit. SBT-01 / 25-PCT 14 19.02.2026

[0062] rotated. Preferably, it is further provided that the carrier part is moved from the first intermediate position to the second intermediate position in a second step and then pivoted from the second intermediate position to the sight-use position in a third step.

[0063] Features described previously or subsequently solely in connection with the proposed visor mechanism or protective helmet can also be transferred to the proposed method, where technically feasible and, if necessary, adapted with regard to the execution of a process step, and thus constitute an independent embodiment of the proposed method. Likewise, features described previously or subsequently solely in connection with the proposed method can also be transferred to the proposed visor mechanism or protective helmet, where technically feasible and, if necessary, adapted with regard to a specific device feature, and thus constitute an independent embodiment. The described features can also be transferred across categories of claims where technically feasible, thereby avoiding unnecessary repetition.

[0064] Further advantageous and preferred embodiments will become apparent from the following description with reference to the figures. The figures, which merely depict exemplary embodiments, show:

[0065] Figure 1 shows a proposed protective helmet with a proposed visor mechanism, in a visor-in-use position, in a perspective view from the front and top;

[0066] Figure 2 shows the protective helmet from Fig. 1 in a side view, still in the visor non-use position;

[0067] Figure 3 shows the protective helmet from Fig. 2 in a side view, now with the visor slightly tilted upwards, starting from the previous visor non-use position; SBT-01 / 25-PCT 15 19.02.2026

[0068] Figure 4 shows the protective helmet from Fig. 3 in a side view, now with the visor shifted downwards, starting from the previous position of Fig. 3;

[0069] Figure 5 shows the protective helmet from Fig. 4, in a cutaway partial view;

[0070] Figure 6 shows the protective helmet from Fig. 4 in a side view, now with the visor swung back again and thus now in the visor-in-use position;

[0071] Figure 7 shows the proposed protective helmet and visor mechanism from the preceding figures in a separate representation, in a perspective view from behind;

[0072] Figure 8 shows a proposed visor mechanism, not mounted on a protective helmet, in a perspective view.

[0073] Fig. 1 shows a perspective view of a proposed protective helmet 80 with a proposed visor mechanism 1 mounted on the front and, in principle, detachably. The visor mechanism 1 is designed for attachment to a protective helmet 80 for emergency personnel. It can also be retrofitted to such a protective helmet 80. The visor mechanism 1 comprises a visor 2, which is also detachably mounted to the visor mechanism 1 by being connected to the support part 10 of the visor mechanism 1. The visor mechanism 1 is shown more clearly as a separate component in Fig. 8, while Fig. 7 shows both the visor mechanism 1 and, separately, the protective helmet 80.

[0074] Fig. 1 shows the protective helmet 80 with the visor mechanism 1 in the visor-not-in-use position. The visor 2 is accordingly positioned above the field of vision or above the front area 94 of the protective helmet 80. Fig. 2 shows the protective helmet 80 in the same visor-not-in-use position, but from a side view, and supplemented in the illustration of Fig. 2 by the dashed central horizontal plane 90 through the protective helmet 80 and the transverse plane 92. In the visor-not-in-use position, the visor 2 is generally located close to the protective helmet 80 or its outer shell 82.

[0075] The visor 2 does not protect a helmet wearer in this position. The support part 10 is arranged above the central horizontal plane 90, but still below the apex 86 of the protective helmet 80, and in front of the transverse plane 92, whereby the entire visor mechanism 1, and therefore also the support part 10, as well as the visor 2, are arranged in all positions in front of the transverse plane 92, i.e. in a front area 84 of the protective helmet 80, as can be seen from the further figures 3 to 6.

[0076] From the visor-inactive position shown in Figs. 1 and 2, the support part 10 and, correspondingly, the visor 2 can be easily moved manually, using only one hand of the helmet wearer, into the intended visor-inactive position, in which the helmet wearer is protected by the visor 2. This visor-inactive position is shown in Fig. 6. Figs. 3 and 4 represent intermediate steps, a first intermediate position, and a second intermediate position, respectively, when moving the support part 10 and the visor 2 into the visor-inactive position. Fig. 5 shows the protective helmet 80 with visor mechanism 1 in a sectional view, in the same situation or position as in Fig. 4. Fig. 7 shows, for illustrative purposes, the visor mechanism 1 detached from the protective helmet 80, while Fig. 8 shows the visor mechanism 1 in isolation.Therefore, all the aforementioned figures will be referred to collectively below, and only to a single figure will certain individual aspects be explicitly referenced.

[0077] The support part 10, and thus the visor 2, can be moved between the visor's operating position and the visor's non-operating position by means of an adjustment movement acting directly on the support part 10 or directly on the visor 2. The helmet wearer can simply grasp the visor 2, for example in the visor's non-operating position as shown in Fig. 1 or Fig. 2, for example on its underside, and then perform the adjustment movement single-handedly. The key feature here is that the adjustment movement is then divided into two different types of movement: the first type of movement is a pivoting movement about the axis of rotation 32, and the second type of movement 40 is a downward movement or, conversely, a movement back upward. SBT-01 / 25-PCT 17 19.02.2026

[0078] Starting from the visor's non-use position, i.e., from Fig. 1 or Fig. 2, the helmet wearer pivots the support part 10 or the visor 2 upwards away from the outer shell 82, as indicated by the dashed arrow 34, which is intended to represent the upward pivoting movement that takes place to move the visor mechanism 1 into the first intermediate position according to Fig.

[0079] to move 3.

[0080] In the first intermediate position according to Fig. 3, the support part 10 or the visor 2 is then further removed from the protective helmet 80 or its outer shell 82, so that a different displacement plane for a subsequent movement of the support part 10 or the visor 2 has now been reached, compared to the previous position according to Fig. 1 or Fig. 2. Now, in the first intermediate position according to Fig. 3, the helmet wearer can move the support part 10 or the visor 2 downwards, as indicated by the dashed arrow 42, which is intended to represent the downward displacement movement that takes place in order to move the protective helmet 80 or the visor mechanism 1 into the second intermediate position according to Fig. 4 (and thus also according to Fig. 6).

[0081] In the second intermediate position according to Fig. 4 (or also according to Fig. 5), the support part 10 and the visor 2 are then moved further downwards, so that space has now been gained for the subsequent movement of the support part 10 or the visor 2, so that the helmet wearer can pivot the support part 10 or the visor 2 back from the second intermediate position according to Fig. 4, namely in the direction of the front area 94, as indicated by the dashed arrow 36, which is intended to represent this pivoting movement back, which takes place in order to put the protective helmet 80 or the visor mechanism 1 into the state according to Fig. 6 and thus into the visor operating position.

[0082] It is advantageously provided that the two movement types 30 and 40 are mutually exclusive in the end positions, meaning that only one of the two movement types can be carried out and the other is blocked. Thus, the support part 10, and therefore the sight 2, cannot be moved back upwards in the sight-use position, as shown in Fig. 6, so that the second movement type 40 is not possible. This can be achieved, for example, by the support part 10 or a part SBT-01 / 25-PCT 18 19.02.2026

[0083] This or the visor 2 itself is blocked by parts of the protective helmet 80, or the visor mechanism 1 is configured such that, for example, the sliding guide 16, which generally provides the possibility of sliding movement (i.e., the second type of movement 40), or the support part 10, is blocked by elements of the visor mechanism 1 or of the protective helmet 80, for example, its front device carrier 88 ("shroud"). In the visor's non-use position (Fig. 1, Fig. 2), sliding is also not possible, i.e., no second type of movement 40, but only pivoting according to the first type of movement 30, since here a kind of wedging and thus a blocking of the support part 10 occurs on the helmet connection unit 22 of the visor mechanism 1, which helmet connection unit 22 serves for the connection with the front device carrier 88. As a result, only pivoting of the support part 10 is always possible.Movement of the visor 2 is possible, while displacement, preferably via a positive locking mechanism of the support part 10 with stationary elements of the visor mechanism 1 or with the protective helmet 80, is blocked. In other words, displacement of the support part 10 or the visor 2 is only possible if the support part 10 and the visor 2 are pivoted forward or upward, at least slightly, from the visor's operating position or the visor's non-operating position, respectively. This provides greater safety in maintaining the two intended end positions, namely the visor's operating position and the visor's non-operating position, as the visor 2 cannot be accidentally moved from these positions.

[0084] The axis of rotation 32, which is provided by the plug-in axle 20 received in the receptacle 21, is arranged above the support part 10 and / or set back from the support part 10. The pivoting movement thus takes place about an axis of rotation 32, which is arranged above the support part 10.

[0085] Adjoining the helmet attachment unit 22 at the top, the visor mechanism 1 has a displacement section 24, which ensures that the receptacle 21 for the stub axis 20, and thus ultimately the rotation axis 32 and therefore the center of the pivoting movement of the first type of movement 30, is offset upwards and, furthermore, to the rearwards due to the displacement section 24's general alignment with the outer shell 82. SBT-01 / 25-PCT 19 19.02.2026

[0086] The sliding guide 16 is articulated to the displacement section 24 by means of the pivot axis 20. The pivot axis 20, or rotation axis 32, is located above the front device carrier 88 in the central area of ​​the protective helmet 80 and allows the sliding guide 16 to rotate relative to the displacement section 24 and – when the visor mechanism 1 is mounted on the protective helmet – allows the sliding guide 16 to rotate relative to the outer shell 82 of the protective helmet 80, in order to pivot the support part 10 about the rotation axis 32. This allows the visor 2, for example, to be lifted from the outer shell 82 or pivoted away from the front area 94.

[0087] The second type of movement 40 can be an upward movement, particularly when viewed from the visor's operating position, as well as a downward movement in the opposite direction (transition from Fig. 3 to Fig. 4). Specifically, the support element 10 is moved from the first intermediate position to the second intermediate position or vice versa. This movement occurs along a path curved back towards the protective helmet 80. This curved path is provided by two brackets 17, which form the sliding guide 16. The support element 10 slides along these two brackets 17 together with the visor 2. The brackets 17 can be rotated together about the axis of rotation 32, which enables the described pivoting movement of the support element 10 about the axis of rotation 32.

[0088] The carrier part 10 has a visor receiving unit 12 into which the visor 2 is inserted and held, and a sliding section 14 designed to guide the carrier part 10 and the visor 2 along the two brackets 17. The carrier part 10 is positioned such that the visor 2 is located below the component of the visor mechanism 1 that provides the adjustment movement, i.e., below the sliding guide 16 that guides the movement of the carrier part 10, and thus below the two brackets 17. In the contact area between the carrier part 10 and the brackets 17, the contact surfaces feature a material pairing designed for improved sliding, with the materials of the contact surfaces being different. Specifically, the brackets 17 are made of POM, while the carrier part 10 is made of PC.The visor 2 therefore moves below the two brackets 17, so that when the visor 2 is adjusted there is no collision with other parts above SBT-01 / 25-PCT 20 19.02.2026.

[0089] This can be achieved with external functional units, such as a night vision device. Such a night vision device can be attached to a top-mounted sight mechanism support 18. This allows any mounted night vision device to be easily pivoted along with the two brackets 17, and the sight 2, along with its support part 10, can then be moved below the night vision device, which has been pivoted upwards by the brackets 17.

[0090] As can be seen in particular from Fig. 4 and Fig. 5, and partly also from Fig. 7 and Fig. 8, the visor mechanism 1 is detachably mounted on the protective helmet 80 by the helmet attachment unit 22 of the visor mechanism 1 being received in the front device carrier 88 (shroud) of the protective helmet 80.

[0091] The visor mechanism 1 further comprises a spring assembly 26, specifically in the form of a torsion spring. The spring assembly 26 exerts a spring force on the brackets 17 and thus on the support part 10 and on the visor 2, which spring force is directed towards the outer shell 82 of the protective helmet 80. The spring force acts against the pivoting of the support part 10 about the axis of rotation 32 upwards or forwards from the front area 94 and thus, conversely, supports the pivoting of the support part 10 and the visor 2 about the axis of rotation 32 in the other, opposite direction of visor displacement. Thus, the spring arrangement 26 pushes the brackets 17 and the visor 2 back to resting against the protective helmet 80 or into the intended position of the visor's use position in the front area 94. The visor 2 is therefore either pushed by the spring arrangement 26 in its non-use visor position towards the outer shell 82, or...in its visor position facing the helmet wearer. This supports the stable maintenance of the respective end positions, i.e., the visor position in use and the visor position out of use, and prevents unwanted swiveling or rattling of the visor 2. The spring assembly 26 guides the brackets, and thus the visor 2, towards the outer shell 82 of the protective helmet 80 in every position.

[0092] Finally, the sighting mechanism 1 also has a locking unit 28, which comprises a movable part 29a and a stationary part 29b. In the sighting position, this allows for two bores: one in the movable part 29a of the locking unit 28, which is integrated into the carrier part 10, and the other in the fixed part 29b.

[0093] The bore in the stationary part 29b must be aligned. A locking pin or similar component can be inserted through the aligned bores. This pin can be attached, for example, to the support part with a certain degree of play, in close proximity to the movable part 29a of the locking unit 28. This secures the movable part of the sight mechanism 1, and thus, for example, the support part 10 and the sight 2, against unwanted movement or pivoting in the sight-in-the-off position. This ensures a secure and stable positioning of the sight 2 during use.

[0094] The proposed visor mechanism 1 advantageously allows a combination of pivoting and sliding mechanisms for adjusting the visor 2 on the protective helmet 80. The mechanism enables flexible adjustment of the visor 2 to various positions without requiring the removal of any external functional units. It is also particularly advantageous that the visor mounting unit 12 of the carrier part 10 is designed to accommodate and connect visors 2 of different widths. According to the common parts concept, this allows the same visor mechanism 1 to be manufactured in large quantities but used for different protective helmets 80 – of different types or widths, i.e., helmet sizes – since only a specific adjustment of the visors 2, which needs to be added to the (same) visor mechanism 1, is required.The central connection of a universal visor mechanism 1 thus enables a largely identical parts concept across different helmet shell sizes.

[0095] Advantageously, the central connection of the visor mechanism 1 leaves other connections or, for example, additional device carriers in the side helmet area free or does not need to be attached separately. This frees up installation space for other external functional units or...

[0096] Equipment components can be used (e.g., adding a mandible).

[0097] Advantageously, the visor 2 is guided and mounted at the minimum possible distance to the outer shell 82 and / or to additional functional components (e.g., the shroud 88) via its adjustment range, thus achieving optimal freedom of use and movement. Furthermore, the visor function remains intact even when attached. SBT-01 / 25-PCT 22 19.02.2026

[0098] Further external functional units or equipment components (especially night vision devices) are fully adaptable and adjustable. SBT-01 / 25-PCT 23 19.02.2026
