[0034] The claimed subject matter is thus based on the astonishing perception that known systems can be further developed to overcome the disadvantages of known systems, by providing an improved assembly being able to provide an accessory, like an inner helmet element, for example a suspension system and / or outer helmet element, for example an anchor element and / or frame, having a small number of parts and being adapted to be assembled without any auxiliary means such as bolts or tools. Furthermore, the claimed subject matter allows a modular configuration of the helmet, in particular to combine different outer shells with different accessories and different numbers of accessories, like different suspension systems frames, anchor elements, outer helmet elements and / or straps, to adapt it in best way to the use purpose and / or to the needs of the user. This in particular reduces the necessity to hold on stock different complete helmet assemblies and thus saves costs. Instead, only a reduced number of outer shells and link elements have to be stored that can be combined with different accessories like suspension elements, frames, anchor elements and chinstrap elements. Also, a reduced number of different link part elements can be combined with each other to adapt it to different outer shells thus reducing the number of link part elements to be held on stock.

[0035] Additionally, the fact that the link element at least partly surrounds and / or grips at least one section of the outer shell allows the link element to fulfill a further function beside connecting the accessory, in particular the helmet suspension, to the outer shell. By the link element a protection function is further fulfilled. The surrounded and / or gripped section of the outer shell is covered. Thus, the section and elements located in this section are protected from outer influences and forces. Furthermore, a user is protected from the section of the outer shell, for example a lower edge of the outer shell. In particular in case the link element comprises a less rigid material than the outer shell, an impact of the section with the user, for example the head of the user, can be dampened, at least its effect and the risk of injuries, can be reduced.

[0036] A further advantage is, that the positioning of the accessory along the perimeter of the helmet and / or outer shell is variable along the extension of the link element.

[0037] Furthermore, the releasable fastening mechanism and / or the holding means, can provide multi-purpose functionalities. The holding means can provide the functionality to connect the accessory, like the helmet suspension, to the outer shell via the link element and additionally or in parallel directly to the outer shell. Also, the releasable fastening mechanism allows to act as an intermediate element to not only connect the accessory, in particular helmet suspension, to the link element but also to additionally connect the link element to the outer shell.

[0038] Further features and advantages of the claimed subj ect-matter will become apparent from the following description of preferred embodiments.

[0042] The link element 20, in particular the edge trim, may not be a part of the accessory, i.e., in this embodiment preferably the helmet suspension 30, and / or the outer shell 3. Furthermore, the link element 20, in particular the edge trim, is adapted to support the accessory, here optionally the helmet suspension 30, in order to couple the accessory, like the helmet suspension 30, to the outer shell 3. Therefore, it might be helpful that the link element 20 extends at least partly along the form of a section of the outer shell 3, the section preferably being an edge, in particular the lower edge 5, of the outer shell 3. According to various embodiments it may be advantageous that the link element 20 at least partly surrounds the lower edge 5 and thus optionally provides a protective function to the lower edge 5 or protects the user from a sharp edge of the lower edge 5. In a preferred embodiment the section, in particular the lower edge 5, has at least partly a substantially horizontal section.

[0043] Figures 2a to 2c show a first step of assembling the protective helmet assembly 1. Thereby, the edge trim 20 is mounted to the outer shell 3 of a protective helmet 2.

[0058] In a further step according to the embodiment of figure 3a to 3c, the accessory, like the helmet suspension 30, is mounted to the protective helmet assembly 1. Therefore, the attaching means 31 of the of the accessory, like the helmet suspension 30, are engaged with the holding means 23 of the edge trim 20, by sliding the first sliding structure 33 of the attaching means 31 into the first guiding structure 24 of the holding means 23. According to the embodiment of figure 3c, the step of sliding ends with an engagement of a part of the guiding structure with a recess 35 of the sliding structure 33. At the same time, a tab of the holding means 23 snaps into the hole 34 as shown in figure 3c.

[0059] In a further step according to figures 4a to 4c, the accessory element, like chinstrap 40, is mounted to the protective helmet assembly 1. Therefore, the linkage means 41 of the accessory element, like the chinstrap 40, are engaged with the holding means 23 and attaching means 31 by sliding the second sliding structure 43 of the linkage means 41 into the second guide structure, which is provided by the holding means 23 and attaching means 31.

[0060] According to the embodiment of figure 4c, the second sliding structure 43 of the linkage means 41 slides between the holding means 23, in particular a part of its guide structure 24, and the attaching means 31 in order to lock the assembly of the protective helmet assembly 1.

[0061] Disassembling the protective helmet assembly 1 follows the logic of figures 2a to 4c backwards. According to various embodiments, releasing the linkage means 41 of the accessory element, in particular in form of the chinstrap 40, may require actuating a second release part, which may correspond to the first release part 25 for releasing the attaching means 31 from the holding means 23. According to the embodiment of figure 4c, the linkage means and thus the accessory element, like the chinstrap 40, are released by pressing the tongue 44. This allows the linkage means 41 to slide off the holding means 23 and attaching means 31. In a second step, the first release part 25 is actuated in order to release the attaching means 31 from the holding means 23 and thus releases the accessory, in particular the helmet suspension 30.

[0062] Figures 5a to 5d show schematic drawings of a second embodiment of a protective helmet assembly 1' realizing an alternative assembling of an, optionally at least one plastic material comprising and or of at least one plastic material consisting, edge trim 20' to an outer shell 3' of the protective helmet 2'. The elements of the protective helmet assembly 1' corresponding to the elements of the protective helmet assembly 1 have the same reference numbers but with one apostrophe.

[0063] As shown in figures 5a to 5c the assembly of the edge trim 20', having a first trim part 21' and a second trim part 22' is mainly identical to the assembling of the edge trim 20 to the outer shell 3 of the protective helmet assembly 1. The edge trim 20' is mounted to a lower edge 5' of the outer shell 3', wherein the lower edge 5' comprises a first edge section 7' and a second edge section 9' similar to the edge sections 7 and 9 of protective helmet 2. Also, the edge trim 20' comprises two link element parts, namely the first trim part 21', which is to be mounted to the first edge section 7', and the second trim part 22', which is to be mounted to the second edge section 9'.

[0064] Contrary to the edge trim 20 the edge trim 20' is mounted to the outer shell 3' of the protective helmet assembly 1' by means of a sliding connection instead of a snapping connection. As shown in the figures 5a to 5d the outer shell 3' comprises slots 51'. In Figure 5d a detailed view of a section of the inner side of the outer shell 3' after the edge trim 20', in particular the first trim part 21', has been connected to the outer shell 3' is depicted. A part of the holding means 23' has been inserted into the slot 51'. The inserted part of the holding means 23' comprises barbs 53' that ensure that the holding means 23' cannot move out of the slot 51'. Thus, a harpoon connection is realized.

[0065] Thus, also the mounting connection between the outer shell 3' and the edge trim 20' does not require any tools, screws, bolts or other aids for mounting. In addition, the edge trim 20' provides four holding means 23' corresponding to four slots 51' formed in the outer shell 3' in order to support the mounting of accessories to the outer shell 3'.

[0066] With the help of Figures 6a to 6w it is now described how a user can configure the protective helmet 2' to meet the personal wishes, specific requirements and needs. To provide the specific required functionalities external functional parts in form of outer helmet elements can be assembled to the outer shell 3' without any further influence on the integrity of the outer shell 3' for example without any fixation means having to pass through the outer shell 3'.

[0067] To allow such an adaptation of the protective helmet 2' to the needed functions respective anchor elements and interconnection elements as described below are attached at least indirectly to the edge trim 20'. The attachment is realized by respective holding means of the link element in form of the edge trim 20' and respective attaching means of the outer helmet elements in form of the anchor elements.

[0068] According to Figure 6a, a first anchor element 55a' in form of a shroud holder is connected via a first holding means 59a' in form of a snap edge of the edge trim 20' and a first attaching means 61a' in form of a snap hook of the anchor element 55a' to the edge trim 20'. Such a snapping allows an attachment without the need of any further tooling and without any influence on the integrity of either the outer shell 3' or the edge trim 20'.

[0069] In Figure 6b the protective helmet assembly 1' is shown in the configuration after the shroud holder 55a' has been attached to the edge trim 20'.

[0070] In Figures 6c and 6d it is shown that two first interconnection elements 57a' in form of front strands are connected to the first anchor element 55a', here the shroud holder. This attachment is also realized by a snap connection but can be realized by any other connection, in particular not needing any further tooling. For example, the first anchor element 55a' and the first interconnection element 57a' might be knotted together in case the first interconnection element 57a' provides a sufficient flexibility. Optionally the strand might comprise a textile material to be knotted with the shroud holder 55a' or might comprise a metal material to be snapped onto the shroud holder 55a'.

[0071] According to figures 6e and 6f second anchor elements 55b' can be connected to the edge trim 20' similar to the first anchor element 55a', in particular without the need of a further tooling. For example, the second anchor elements 55b' might represent adapter holders for respective accessories as explained later. To ensure that the anchor elements 55b' are and stay in contact with the outer shell 3' the anchor elements 55a' and 55b' are connected by the first interconnection elements 57a'. In this way not only a form fit but also a force fit of the anchor elements 55a' and 55b' with the outer shell 3' is ensured. In particular a tilting of the anchor elements 55a' and 55b' around the edge trim, for example due to the weight of an accessory connected to the anchor element, can be avoided.

[0072] To ensure the force fit of the anchor elements to the outer shell 3' the second anchor elements 55b' are connected to each other. As shown in Figures 6g to 6k this connection is realized by a third anchor element 55c' comprising at least one rear base and second interconnection elements 57b' in form of rear strands. After positioning the third anchor element 55c', here the rear base, on the surface of the outer shell 3' as shown in figures 6g and 6h, respectively, the third anchor element 55c' is connected to the second anchor elements 55b' in form of the adapter holders as shown in figures 6i and 6j, respectively. In contrast to the first and second anchor elements 55a' and 55b' that are directly connected to the edge trim 20', the third anchor element 55c' is indirectly connected to the edge trim via the second anchor elements 55b', here in form of the adapter holders.

[0073] For the connection of the second anchor elements 55b' and the third anchor element 55c', respective second interconnection elements 57b', optionally in form of rear strands, are connected to both the second and third anchor elements 55b', 55c'.

[0074] As shown in figure 6k by the anchor elements 55a', 55b', 55c' and the interconnection elements 57a' and 57b' a frame is provided that is connected in form and force fit manner to the outer shell 3', in particular via the edge trim 20'.

[0075] As apparent for the skilled person from the above description the frame has a modular configuration. By exchanging the respective anchor elements and / or interconnection elements shown in the figures by other anchor elements and / or interconnection elements having different lengths, forms, strengths and / or other geometrical dimensions, the frame can be adapted to respective different outer shells having for example different sizes, forms and / or surface structures.

[0076] To avoid an unintended disassembling of the frame under normal use conditions, in particular a disconnection of the anchor elements 55a', 55b', 55c' and the interconnection elements 57a', 57b' it is preferred that the connection of these elements is secured by a further connection, for example a screw connection 63'. By such a further connection the frame is locked / blocked. Alternatively, or additionally, at least one of the anchor elements and / or the interconnection elements might comprise at least one tensioning mechanism to adjust the connection force of the anchor elements and interconnection elements to each other and / or the outer shell 3'. As shown in figures 6k and 6j the screw connection 63' can be integrated in the third anchor element 55c', in particular the rear base and simultaneously can provide a tension means in which by the screw connection the width of the rear base and thus the distance between the second interconnection elements 57b' can be adapted. One end of the screw connection 63' may include knurling thereof to facilitate tightening / loosening of the screw connection 63' by hand, without the need for a tool. Alternatively, the screw connection 63' may include, for example, a slotted head, Phillips head, or torx head that facilitates tightening / loosening with a driver tool (the driver tool may be, for example, incorporated into one or more of the outer helmet elements such as the cover element 65' as described below).

[0077] In particular to avoid an unintentional disconnection of the anchor elements 55a', 55b', 55c' and of the interconnection elements 57a', 57b' from each other at least one of said anchor elements and / or of said interconnection elements might be covered by a cover element.

[0078] In this embodiment the rear base 55c' is covered by a cover element 65' in form of a rear base cover. The rear base cover 65' is snapped and / or attached on the rear base 55c'. Although not shown, the cover element 65' (or another accessory component) may include an integrated driver (e.g., slotted head driver, Phillips head driver, torx head driver, etc.) that facilitates tightening / loosening of the screw connection 63'. In particular in this way no further tool not comprised by the helmet assembly is necessary for assembly / disassembly.

[0079] The before described frame formed by the outer helmet elements 55a', 55b', 55c', 57a', 57b', 65' allows the connection of ample functional elements and / or accessories to the protective helmet assembly 1'.

[0080] For example, according to figures 6n to 6q alternatively and / or additionally an accessory, in particular also forming an outer helmet element, like a shroud 67' can be connected to the first anchor element 55a' in form of the shroud holder. To secure the connection between the shroud 67' and the shroud holder 55a' a screw via a screw lock 69' is used. One end of the screw lock 69' may include knurling thereof to facilitate tightening / loosening of the screw connection 69' by hand, without the need for a tool. Alternatively, the screw lock 69' may include, for example, a slotted head, Phillips head, or torx head that facilitates tightening / loosening with a driver tool (as previously mentioned, the driver tool may be incorporated into one or more of the outer helmet elements, for example, the cover element 65').

[0081] As shown in figures 6r to 6s it is possible that to the frame and / or the second anchor element 55b', in particular the adapter holder, an accessory in form of a side and / or ear protection element 71' can be connected.

[0082] According to figures 6t to 6w alternatively or additionally a further accessory in form of at least one, optional a plurality of rail adapters 73' to provide a normalized interface for further accessories of functional component can be connected to the second anchor element 55b'. The rail adapters 73' can be clipped onto the adapter holder 55b' wherein the clip connection can be secured by at least one screw lock 75'.

[0083] It is important to note that none of the outer helmet elements 55a', 55b', 55c', 57a', 57b' needs a connection that would make an interference with the integrity of the outer shell 3' necessary, for example drilling hole or openings into the outer shell 3'. Also, the screw locks 69' and 75' do not make any integrity change of the outer shell 3' necessary. The screw locks are in particular provided between outer helmet elements being indirectly connected to the outer shell 3' via the edge trim 20' and / or the frame connected to the outer shell 3' in a form and force fit manner.
