Description

[0001] Helmet system and helmet shell for the helmet system

[0002] The present invention relates to a helmet system comprising a helmet shell and a helmet cover for covering ventilation openings of the helmet shell. The invention further relates to a helmet shell for the helmet system.

[0003] Helmets have different functional requirements depending on their intended use and the duration of their use. On hot days, for example, good ventilation is desirable. On rainy days, however, a helmet shell that is as closed as possible is preferred for adequate weather protection. In cycling, a closed helmet shell is preferred for the best possible aerodynamics. For longer uphill rides, however, a helmet shell with the best possible ventilation is desired.

[0004] Helmets that can be modified for different purposes are known in the prior art. For example, bicycle helmets with relatively large ventilation openings and additionally available closure inserts are known. The closure inserts can be positioned in the ventilation openings to improve the aerodynamics of the bicycle helmet. Furthermore, it is known to provide a helmet cover for a helmet with ventilation openings, which can be positioned on the helmet, and in particular over the ventilation openings, if necessary. Various magnetic and mechanical fastening mechanisms are known for attaching the helmet cover to the helmet or helmet shell.

[0005] WO 98 / 46095 A2 discloses a two-piece safety helmet comprising a well-ventilated, one-piece inner core and an outer shell with perforations. The core has continuous channels extending from the front to the back of the helmet, with continuous ribs on one side that are rounded to minimize contact between the ribs and the head.

[0006] From KR 2020180000533 U a helmet is known which has a heat sensor and is equipped with a display that shows the heat detected inside the helmet.

[0007] From CN 217906482 U a riding helmet is known which has a cover plate for covering an upper ventilation opening on the helmet.

[0008] The object of the present invention is to create an improved helmet system in which ventilation openings of a helmet shell can be opened and closed as quickly and easily as possible.

[0009] The above object is achieved by the patent claims. In particular, the above object is achieved by the helmet system according to claim 1, as well as the helmet shell and helmet cover according to the independent claims. Further advantages of the disclosed invention emerge from the dependent claims, the description, and the figures. Features described in connection with the helmet system also apply in connection with the helmet shell and the helmet cover, and vice versa, so that with regard to the disclosure, reference is and / or can always be made to the individual aspects.

[0010] According to a first aspect of the present invention, an improved helmet system is proposed. The helmet system comprises a helmet shell with protective ribs, helmet shell ventilation openings, and at least one bearing web formed on at least one protective rib and in at least one helmet shell ventilation opening. The helmet system also comprises a helmet cover for covering the helmet shell ventilation openings. Furthermore, the helmet system comprises a fastening unit for positively and / or non-positively fastening the helmet cover to the at least one bearing web.

[0011] Within the scope of the present development, it was recognized that the bearing webs according to the invention can be used not only to stabilize the helmet structure, but also as a specific bearing location for add-on components on the helmet shell. The proposed bearing webs are therefore designed to be so stable that, when the helmet cover is repeatedly attached to the helmet shell and repeatedly detached from the helmet shell, as little damage as possible occurs to the bearing webs and / or the helmet shell. Furthermore, the bearing webs have a fastening geometry that is suitable for non-destructive and / or low-wear fastening of the helmet cover. Particularly flat web sections, which could quickly wear out and / or break during fastening of the helmet cover to at least one bearing web, are avoided wherever possible.The bearing webs are preferably arranged in such a way that they span a helmet shell ventilation opening and preferably connect two opposing protective ribs.

[0012] A helmet shell can be understood as a basic structural body for a helmet, in particular for a protective helmet for protecting the head of a person wearing the helmet. In addition to a shell structure, the helmet shell can also have a holding mechanism installed on the shell structure, for example a holding strap, for holding the shell structure to a person's head. A helmet shell can be understood as a helmet such as a bicycle helmet, a skateboard helmet, a climbing helmet or a construction helmet. A bicycle helmet can be understood as a helmet that has been specifically developed for cyclists to protect the cyclist's head in the event of a fall or accident. A climbing helmet can be understood as a helmet that has been specifically designed for skateboarders and scooter riders to prevent injuries in the event of a fall or when performing tricks.A climbing helmet can be understood as a helmet designed for mountaineers and climbers to protect the wearer from falling rocks and other hazards encountered during mountaineering. A construction helmet can be understood as a work helmet and / or safety helmet worn by workers on construction sites and in other hazardous work environments to protect the head from injuries caused by falling objects or impacts. It is not common practice, particularly for mountaineering helmets, skateboard helmets, and construction helmets, to provide larger helmet shell ventilation openings in the home helmet. The proposed helmet system and the simple yet reliable attachment option for the helmet cover could change this.

[0013] The helmet cover is preferably designed as a one-piece and / or monolithic component. This allows the helmet cover to be used quickly and easily. Furthermore, the helmet cover can be manufactured quickly and easily. Furthermore, the helmet cover is less likely to be misplaced or lost, for example, compared to several separate closure inserts. The helmet system can be in a disassembled state, in which the helmet cover is removed from the helmet shell, and in an assembled state, in which the helmet cover is attached to the helmet shell.

[0014] Helmet shell ventilation openings can be understood as through-openings or holes in the helmet shell that serve to enable air circulation and airflow around the head of a helmet shell wearer. The helmet shell ventilation openings can be designed as elongated holes. The elongated holes can be longer than 5 cm, longer than 10 cm, or longer than 15 cm. The elongated holes can be wider than 1 cm or wider than 2 cm. The helmet shell ventilation openings are strategically placed to dissipate the heat and moisture that can accumulate under the helmet shell, thereby increasing wearer comfort. The helmet shell ventilation openings can therefore help keep the helmet wearer's head as cool as possible and reduce sweating. The number and size of the helmet shell ventilation openings can vary depending on the design and intended use of the helmet shell.The helmet shell can, for example, have one, two, three, four, five, six, seven or more protective ribs. The helmet cover can, for example, have two, three, four, five, six, seven, eight or more helmet shell ventilation openings. If the helmet shell has, for example, four protective ribs, five helmet shell ventilation openings can be formed between the protective ribs and a frame region or a side structure of the helmet shell. The helmet shell ventilation openings preferably have an elongated shape. The helmet shell ventilation openings and / or the protective ribs can each extend from a front region of the helmet shell across a middle region of the helmet shell into a rear region of the helmet shell. The front region of the helmet shell can be understood to be a region that is located in front of a center of the helmet shell in a longitudinal direction of the helmet shell.The front region of the helmet shell can also be understood as the region of the helmet shell that, when the helmet shell is worn on the head of a wearer or user, is positioned at least partially in the front of the head and / or in the forehead region of the user. The rear region of the helmet shell can also be understood as a region that is located behind a center of the helmet shell in a longitudinal direction of the helmet shell. The rear region of the helmet shell can also be understood as the region of the helmet shell that, when the helmet shell is worn on the head of the user, is positioned at least partially in the back of the head of the user.

[0015] The at least one bearing web can be understood as a structural component that is fastened in and / or on a helmet shell ventilation opening between two protective ribs and / or to the protective ribs. The at least one bearing web can be positioned transversely to a longitudinal direction of the protective ribs and / or transversely to a longitudinal direction of the helmet shell. The at least one bearing web and / or selected bearing webs can be positioned orthogonally or approximately orthogonally to a longitudinal direction of the protective ribs and / or orthogonally or approximately orthogonally to a longitudinal direction of the helmet shell. The at least one bearing web can be fastened between a protective rib and an edge region of the helmet shell or to this protective rib and the edge region. The helmet shell can have a plurality of bearing webs, which, as described above, can each be fastened between two protective ribs and / or to the protective ribs.The bearing webs or some of the bearing webs can each be fastened between a protective rib and an edge region of the helmet shell. Multiple bearing webs can be positioned in and / or on each helmet shell ventilation opening. Accordingly, multiple bearing webs can be fastened between the same protective ribs and / or on the same protective rib. The bearing webs can be positioned parallel to one another or approximately parallel to one another. In particular, bearing webs positioned in and / or on the same helmet shell ventilation opening can be positioned parallel or approximately parallel to one another. Furthermore, bearing webs positioned on the same side of a protective rib can be positioned parallel or approximately parallel to one another. If the helmet shell has multiple bearing webs, not every one of the bearing webs has to be used as a fastening base for the fastening unit and / or the helmet cover.This means that the helmet cover can be positively and / or non-positively attached to several bearing webs by means of the fastening unit, while at other bearing webs no physical contact is made with the helmet cover and / or the fastening unit.

[0016] The at least one bearing web and / or the bearing webs are preferably designed and positioned in such a way that the ventilation function of the helmet shell ventilation openings is not impaired or is impaired as little as possible.

[0017] Covering the helmet shell ventilation openings can be understood as completely covering or partially covering the helmet shell ventilation openings. Partially covering the helmet shell ventilation openings can be understood as reducing the cross-sectional area of ​​the helmet shell ventilation openings, for example by designing cover web ventilation openings in the helmet cover, each of which is smaller than the covered helmet shell ventilation openings and / or each has a smaller cross-sectional area than the helmet cover ventilation openings. Covering the helmet shell ventilation openings can be understood as completely closing the helmet shell ventilation openings and / or partially closing the helmet shell ventilation openings.At least partially covering and / or closing the helmet shell ventilation openings can lead to improved weather protection and / or improved aerodynamics of the helmet shell. Covering can therefore be understood as covering to improve aerodynamics and / or to improve weather protection. The fastening unit can be configured for non-destructively detachable fastening of the helmet cover to the at least one bearing web. According to a further embodiment, it is possible for the fastening unit in a helmet system to have at least one bearing web fastening hook that is configured to hook into at least one bearing web. By means of the bearing web fastening hook, the helmet cover can be fastened particularly quickly and easily to the helmet shell or to the at least one bearing web. The bearing web fastening hook can be understood as a fastening means for hooking onto the bearing web.The bearing web fastening hook can be hook-shaped, L-shaped, claw-shaped, and / or configured with a suitable recess, a recess, a stop, and / or an undercut to fulfill the desired hook function. This means that the bearing web fastening hook does not have to be projection-like or in the form of a conventional hook. The fastening unit can have several spaced-apart bearing web fastening hooks, for example, two, three, four, or more bearing web fastening hooks. The at least one bearing web fastening hook can be attached to and / or configured on a cover web as described above. A bearing web fastening hook can be configured on each of the different cover webs, for example, as an integral and / or monolithic component of the respective cover web.The at least one bearing web fastening hook can be configured or designed to hook into the at least one bearing web with some play. This means that if a bearing web fastening hook is hooked onto a bearing web, there can be bearing play and / or hook play between the bearing web fastening hook and the bearing web. The bearing play can exist in particular until the helmet cover has been finally fastened to the helmet shell by another fastening means. In this way, the helmet cover can be fastened to the helmet shell particularly quickly and easily. More precisely, the helmet cover can be brought into a first fastening position particularly quickly and easily in this way, after which the helmet cover can be brought into a second and / or final fastening position by an optional further movement.Hooking can therefore be understood as a loose hooking, for example, not a locking and / or snapping hooking. The bearing bar fastening hook is preferably designed on an underside of the helmet cover. In the assembled state, the underside is located on the helmet shell or at least partially faces the helmet shell. In the assembled state, an upper side of the helmet shell faces away or essentially away from the helmet shell.

[0018] Furthermore, in the helmet system described here, it is possible for the at least one bearing bar fastening hook to be designed as a monolithic and / or integral component of the helmet cover. This allows the helmet cover to be manufactured quickly and easily. Furthermore, the bearing bar fastening hook is thus securely attached to the helmet cover. The helmet cover can be designed, for example, as a monolithic plastic component, for example, as an injection-molded component.

[0019] The helmet cover can have spaced-apart cover bars for covering the helmet shell ventilation openings, wherein the at least one bearing bar fastening hook is configured on at least one cover bar. In this way, the helmet system is particularly compact in the assembled state. The cover bars can be connected to one another by a frame structure. Through-openings can be formed between the cover bars, which can be configured to complement the protective ribs. The helmet cover ventilation openings described above can be configured and / or formed in the cover bars. The cover bars, or at least some of the cover bars, can have a V-shaped cross-section, a trapezoidal cross-section, and / or a wedge-shaped underside. This allows the helmet cover to be positioned particularly quickly and easily on and at least partially in the helmet shell ventilation openings.The helmet shell ventilation openings or the protective ribs can have a correspondingly complementary shape. For example, the protective ribs can have at least one guide bevel for guiding the cover webs into the helmet shell guide openings. The helmet cover can, for example, have two, three, four, five, six, seven, or more bearing webs. The bearing webs, mounted on the helmet shell, can be spaced apart from one another and extend from the front region of the helmet shell to the rear region of the helmet shell. At least one bearing web fastening hook can be configured on each of different and spaced-apart cover webs. For example, a first bearing web fastening hook for a first bearing web can be configured on a first cover web, and a second bearing web fastening hook for a second bearing web can be configured on a second, separate cover web.In this way, an even distribution of forces can be created in the helmet cover and on the bearing bars when attaching the helmet cover to the helmet shell.

[0020] Furthermore, it is possible for the proposed helmet cover to have spaced-apart cover bars for covering the helmet shell ventilation openings, wherein at least one cover bar ventilation opening is configured in at least one cover bar, and the at least one bearing bar fastening hook is configured in a ventilation opening edge region that defines the at least one cover bar ventilation opening. In this way, the at least one bearing bar fastening hook can be designed to be particularly space-saving. The ventilation opening edge region can form a structural section of the helmet cover, which is designed to be comparatively stable. The at least one cover bar fastening hook can therefore be designed to be particularly stable and correspondingly durable in this region and / or as part of this region, without unnecessarily negatively affecting the shape and / or weight of the helmet cover.The at least one cover bar fastening hook can be configured in pairs or in pairs in the ventilation opening edge region, particularly on opposite side walls of the ventilation opening edge region. The at least one cover bar fastening hook can be configured at least partially as a recess and / or depression in the ventilation opening edge region or in an associated side wall.

[0021] Furthermore, with the proposed helmet system, it is possible for the helmet shell to have a helmet rim and for the fastening unit to have a helmet rim fastening means, wherein the helmet rim fastening means is designed for the positive and / or non-positive fastening of the helmet cover to the helmet rim. In this way, the helmet cover can be fastened to the helmet shell particularly quickly and easily. The helmet rim fastening means can be designed in addition to the at least one bearing web fastening hook. Thus, a user of the helmet system can, for example, first fasten or fix the helmet cover to the associated at least one bearing web using the at least one bearing web fastening hook and then additionally fasten the helmet cover to the helmet rim using the helmet rim fastening means.For particularly stable attachment, the helmet rim can have an undercut and / or a tapered outer helmet edge with an acute cross-sectional angle, whereby the helmet rim fastening means can be designed for positive and / or force-fitting attachment of the helmet cover to the undercut and / or to the pointed outer helmet edge. The helmet rim can be understood as a helmet rim section on a front and / or rear side of the helmet shell. In the helmet system described here, the helmet rim fastening means can be designed as a monolithic and / or integral component of the helmet cover. This also allows the helmet cover to be manufactured particularly quickly and easily. Furthermore, the helmet rim fastening means is thus firmly attached to the helmet cover or as a correspondingly stable part of the helmet cover.

[0022] Furthermore, with the proposed helmet system, it is possible for the helmet rim fastening means to have a locking lip or to be designed as a locking lip. Using the locking lip, the helmet cover can be quickly and easily attached to the helmet shell or additionally secured. The locking lip can create a relatively large-area snap connection and / or locking connection with the helmet rim. This allows the helmet rim fastening means to be used with particularly low wear and a correspondingly long service life. Such a locking lip is also particularly easy to manufacture. The locking lip can be understood as a folded-over edge region of the helmet cover. The locking lip can also be understood as an edge region of the helmet cover that has a lip shape, curved wall and / or undercut complementary to the helmet rim.The locking lip and / or the associated part of the helmet rim fastening means can be designed to be flexible and / or elastically deformable such that the locking lip and / or the helmet rim fastening means can be elastically deformed during attachment to the helmet rim. The locking lip or at least a part of the locking lip can be designed as an integral and / or monolithic component of the helmet shell.

[0023] Furthermore, it is possible for the fastening unit of the proposed helmet system to have at least one bearing web locking means configured to establish a locking connection with the at least one bearing web. The bearing web locking means allows the helmet cover to be particularly easily and securely fastened to the helmet shell. The at least one bearing web locking means can be configured in addition to or as an alternative to the at least one bearing web fastening hook and in addition to or as an alternative to the helmet rim fastening means. For example, the helmet cover can have a plurality of spaced-apart bearing web fastening hooks in the front region of the helmet cover and a plurality of spaced-apart bearing web locking means in the rear region of the helmet cover. A bearing web locking means can be understood to mean a locking means for establishing a locking connection, a snap connection, and / or a clip connection with at least one of the bearing webs.For this purpose, the at least one bearing web can have a circular or cuboid-shaped cross-section. It is advantageous if the bearing webs are not too delicately designed. The at least one bearing web locking means can have an undercut to establish the locking connection. The at least one bearing web locking means can be designed to be elastically deformable to establish the locking connection.

[0024] In the helmet system described here, the bearing bar locking device can be configured as a monolithic and / or integral component of the helmet cover. This allows the helmet cover to be manufactured particularly quickly and easily. Furthermore, the bearing bar locking device can be designed to be rigidly attached to the helmet cover or as a correspondingly stable part of the helmet cover.

[0025] Furthermore, a helmet system is proposed in which the helmet cover has the above-described front region and the above-described rear region and - wherein the at least one bearing web fastening hook is designed in the front region and the helmet rim fastening means is designed in the rear region and / or

[0026] - wherein the at least one bearing web fastening hook is designed in the rear region and the helmet rim fastening means is designed in the front region and / or

[0027] - wherein the at least one bearing web fastening hook is configured in the front region and the at least one bearing web locking means is configured in the rear region and / or

[0028] - wherein the at least one bearing web fastening hook is configured in the front region and the at least one bearing web locking means is configured in the rear region.

[0029] In simple terms, the fastening unit can have at least one bearing bar fastening hook in the front or rear area and a locking device in the other area. This allows the helmet cover to be attached to the helmet shell particularly quickly, easily, and yet securely.

[0030] The helmet system can further comprise a plurality of bearing webs, wherein a bearing web configured for hooking the at least one bearing web fastening hook and / or for providing the latching connection with the at least one bearing web latching means has a higher strength than a bearing web that is not configured for hooking the at least one bearing web fastening hook and / or for providing the latching connection with the at least one bearing web latching means. This means that the bearing webs can be designed with different strengths, for example by using different materials for the bearing web latching means and / or by using different geometries of materials for the bearing web latching means. In this way, it is possible, for example, to configure only the bearing webs to which the helmet cover or the fastening unit is to be attached later with the desired strength and / or geometry.This can, for example, prevent the helmet shell from becoming unnecessarily heavy. The robust manufacturing of selected bearing bars can also improve the longevity of the helmet system.

[0031] Furthermore, the proposed helmet system can have a plurality of bearing webs, wherein a bearing web that is configured for hooking the at least one bearing web fastening hook and / or for providing the latching connection with the at least one bearing web latching means has a different visual design than a bearing web that is not configured for hooking the at least one bearing web fastening hook and / or for providing the latching connection with the at least one bearing web latching means. This can simplify use of the helmet system for the user. The different visual appearance allows the user to see at a glance to which bearing web or webs the helmet cover is to be attached, thus gaining a better feel for the most intuitive attachment process possible. The different visual appearance can be understood, for example, as different colors and / or different shapes of the bearing webs.For example, the at least one bearing web to which the fastening unit is to be fastened can have a different color and / or a different shape than at least one further bearing web to which the fastening unit is not to be fastened.

[0032] A further aspect of the invention relates to a helmet shell for a helmet system as described above. The helmet shell has protective ribs, helmet shell ventilation openings, and at least one bearing web formed on at least one protective rib and in at least one helmet shell ventilation opening, wherein the at least one bearing web is configured for attaching a helmet cover. The helmet shell thus offers the same advantages as have been described in detail with reference to the helmet system. The helmet shell can, even considered on its own and / or claimed on its own, have all of the functional features and / or embodiments of the helmet shell described above. In particular, the helmet shell can have bearing webs designed to be sufficiently stable and appropriately dimensioned specifically for attaching the helmet cover.

[0033] Furthermore, one aspect of the present invention relates to a helmet cover for a helmet system as described above, according to one of the preceding claims, which is configured to cover the helmet shell ventilation openings and has a fastening unit for positively and / or non-positively fastening the helmet cover to the at least one bearing web. Thus, the helmet cover also provides the advantages described above. The helmet cover, even considered on its own and / or claimed on its own, can have all of the above-described functional features and / or embodiments of the helmet cover.In particular, the fastening unit can be designed as an integral and / or monolithic component of the helmet cover, which can have at least one bearing web fastening hook, which can have at least one helmet rim fastening means, which can have at least one bearing web locking means, which can have cover webs and / or which can have cover web ventilation openings.

[0034] Further measures will become apparent from the following description of various exemplary embodiments, which are schematically illustrated in the figures. All features and / or advantages arising from the claims, the description, or the figures, including structural details and spatial arrangements, may be significant both individually and in various combinations.

[0042] Elements with the same function and mode of operation are provided with the same reference symbols in the figures.

[0043] Fig. 1 shows a helmet system 10 with a helmet shell 11 and a helmet cover 15. The helmet shell 11 is designed in the form of a bicycle helmet. The helmet cover 15 is designed in the form of an aero helmet cover to improve the aerodynamics of the helmet shell 11. The helmet shell 11 has four protective ribs 12 which extend next to one another and spaced from one another in a longitudinal direction 28 of the helmet shell 11 from a front region 23 of the helmet shell 11 into a rear region 24 of the helmet shell 15. Helmet shell ventilation openings 13 are formed between the protective ribs 12 and, like the protective ribs 12, extend next to one another and spaced from one another from the front region 23 of the helmet shell 11 into the rear region 24 of the helmet shell 15. Two helmet shell ventilation openings 13 are each formed between a protective rib 12 and a side structure 25 of the helmet shell 11.

[0044] The helmet shell 11 shown has several bearing webs 14 which are attached to the protective ribs

[0045] 12 and in various helmet shell ventilation openings 13 are positioned and designed accordingly. More precisely, three bearing webs 14 are designed in a left helmet shell ventilation opening 13 and in a right helmet shell ventilation opening 13, whereby these helmet shell ventilation openings

[0046] 13 are each formed between a protective rib 12 and the side structure 25. In two further helmet shell ventilation openings 13, each extending between two protective ribs 12, four bearing webs 14 are each formed and attached in pairs to the respective protective ribs 12.

[0047] The helmet cover 15 shown in Fig. 1 is configured to partially cover the helmet shell ventilation openings 13. For this purpose, the helmet cover 15 has five cover webs 18 that extend next to one another and at a distance from one another. The cover webs 18 are designed to complement the helmet shell ventilation openings 13. More precisely, an outer contour of the cover webs 18 is designed to be complementary or partially complementary to an inner contour of the helmet shell ventilation openings 13, so that the cover webs 18 can be positioned in a correspondingly form-fitting manner in or on the helmet shell ventilation openings 13. A cover web ventilation opening 26 is formed in each of the three middle cover webs 18. This means that the three middle cover bars 18 each define a cover bar ventilation opening 26. The cover bar ventilation openings 26 are positioned in the front area 23 of the helmet shell 11 in the assembled state.

[0048] The helmet cover 15 shown in Fig. 1 has a fastening unit 16, by means of which the helmet cover 15 can be fastened to the helmet shell 11. The fastening unit 16 is designed, among other things, for the frictional fastening of the helmet cover 15 to selected support webs 14. In the illustrated embodiment, the fastening unit 16 has three support web fastening hooks 17 (shown in detail in Fig. 3) and a helmet rim fastening means 21. The support web fastening hooks 17 are configured for hooking into selected support webs 14 and are designed as a monolithic component of the helmet cover 15. The support web fastening hooks 17 are designed in a projection-like manner on three different and spaced-apart cover webs 18. The helmet rim fastening means 21 is for the positive and non-positive fastening of the helmet cover 15 to the helmet rim 19 and in particular to an undercut 20 ora pointed edge of the helmet rim 19. The helmet rim fastening means 21 is in the form of a locking lip and is designed as a monolithic component of the helmet cover 15. By means of the locking lip, a non-destructively releasable locking or snap connection can be established between the helmet rim 19 and the helmet rim fastening means 21.

[0049] Fig. 2 shows the helmet system 10 shown in Fig. 1 in an assembled state, in which the three bearing web fastening hooks 17 are hooked into or onto three associated bearing webs 14 and a snap-in connection is established between the helmet rim 19 and the helmet rim fastening means 21 (not shown in detail in Fig. 2 for better clarity). Fig. 3 shows the helmet cover 15 shown in Fig. 1 with a view of an underside of the helmet cover 15. This allows the three bearing web fastening hooks 17 of this embodiment to be seen in detail. In addition, the lip-shaped helmet rim fastening means 21 can be seen, by means of which the snap-in connection between the helmet rim 19 and the helmet rim fastening means 21 can be established.

[0050] Fig. 4 shows a helmet cover 15 according to a second embodiment. In the embodiment shown in Fig. 4, a cover web ventilation opening 26 is formed in each of three cover webs 18, wherein the bearing web fastening hooks 17 are each formed in a ventilation opening edge region 27 that defines the respective cover web ventilation opening 26. More precisely, two bearing web fastening hooks 17 are arranged opposite one another or next to one another in the respective ventilation opening edge region 27. The bearing web fastening hooks 17 each have a recess or notch in the ventilation opening edge region 27. In addition, the bearing web fastening hooks 17 each have a guide projection 31, which is designed in a projection-like manner on the respective ventilation opening edge region 27 and on the respective recess.The guide projection 31 enables a user of the helmet system 10 to more easily attach the bearing web fastening hooks 17 to the bearing webs 14 or to more easily guide the bearing webs 14 into the bearing web fastening hooks 17.

[0051] Fig. 5 shows a helmet cover 15 according to a third embodiment. In this helmet cover 15, the fastening unit 16 has three bearing web locking means 22 on three different cover webs 18. In other words, the fastening unit 16 has the bearing web locking means 22 instead of the bearing web fastening hooks 17 shown in Fig. 3. The bearing web locking means 22 are configured to establish a locking connection with the respective bearing webs 14. Furthermore, the bearing web locking means 22 are designed as a monolithic component of the helmet cover 15. The bearing web locking means 22 shown have a V-shaped and / or tapered locking receptacle into which the bearing webs 14 can be inserted in an end section of the respective bearing web locking means until the locking connection is established.

[0052] Fig. 6 shows a helmet cover 15 according to a fourth embodiment. This helmet cover 15 has the three bearing web fastening hooks 17 shown in Fig. 3 and additionally three bearing web locking means 22, which are designed in place of the locking lip. The bearing web locking means 22 each have a locking hook to establish the desired locking connection with the respective bearing webs 14.

[0053] The invention disclosed here allows for further design principles in addition to the embodiments shown. This means that the invention should not be considered limited to the embodiments explained with reference to the figures.

[0054] As can be seen from Figures 3, 4 and 6, it can be advantageous for a quick yet secure attachment of the helmet cover 15 to the helmet shell 11 if at least one bearing web attachment hook 17 is configured in the front region 23 and at least one helmet rim attachment means 21 is configured in the rear region 24. In a similar way, it can be advantageous if at least one bearing web attachment hook 17 is configured in the rear region 24 and the helmet rim attachment means 21 is configured in the front region 23. Furthermore, it can be correspondingly advantageous if at least one bearing web attachment hook 17 is configured in the front region 23 and at least one bearing web locking means 22 is configured in the rear region 24.Furthermore, it may be advantageous if at least one bearing web fastening hook 17 is designed in the front region 23 and at least one bearing web locking means 22 is designed in the rear region 24.

[0055] Furthermore, a bearing web 14 that is configured for hooking the at least one bearing web fastening hook 17 and / or for providing the locking connection with the at least one bearing web locking means 22 can have a higher strength than a bearing web 14 that is not configured for hooking the at least one bearing web fastening hook 17 and / or for providing the locking connection with the at least one bearing web locking means 22. In addition, a bearing web 14 that is configured for hooking the at least one bearing web fastening hook 17 and / or for providing the locking connection with the at least one bearing web locking means 22 can have a different visual appearance than a bearing web 14 that is not configured for hooking the at least one bearing web fastening hook 17 and / or for providing the locking connection with the at least one bearing web locking means 22.

[0056] Furthermore, it is possible for the helmet system 10 to be configured not only as a bicycle helmet system, but also, for example, as a mountain helmet system, a skateboard helmet system, and / or a construction helmet system. In this case, the helmet cover 15 may, for example, not be used, or not only used, to improve the aerodynamics of the helmet shell 11, but rather specifically for improved weather protection of the helmet shell 11, and may be modified accordingly.
