Description

Technical Field

[0001] The present invention relates to a protective headgear comprising a curved headgear shell, a curved damping shell and a retaining ring. In addition, the present invention also relates to a method for producing such a protective headgear. Background Art

[0002] Protective headgear protects the wearer's head from mechanical, chemical, and / or thermal environmental influences. Such protective headgear typically comprises a curved headgear shell made of a rigid material, wherein the headgear shell encloses an area, which may be referred to as the interior of the protective headgear. Typically, a supporting structure holds an inner device having textile components, wherein the inner device is in contact with the wearer's head and wherein the supporting structure helps to position the protective headgear in the desired position on the wearer's head.

[0003] A known method is to install a curved damping shell between the curved helmet shell and the internal device. The damping shell rests on the helmet shell from the inside and absorbs the kinetic energy acting on the helmet shell from the outside.

[0004] One possibility for fixing the damping shell in the protective headgear is to connect the damping shell to the interior of the headgear shell, for example, by adhesive bonding or by fusing it with a foamed connecting material.

[0005] US 2010 / 0 043 126 A1 describes a protective helmet 1 having a main outer shell 2, an inner shell 13 and a supporting structure 11, both of which are arranged in the helmet shell 2, and a chin strap 12. The supporting structure 11 is fixed to the helmet shell 2 at four fixing points 16, 17, 18a, and 18b with a positive fit. The inner shell 13 is fixed to the supporting structure 11 by clamping.

[0006] DE 10 2010 050 678 B3 describes a protective headgear having a rigid outer shell 1, a headband 8 and a basket-like carrier 11 with a projection arrangement 12. The projection arrangement 12 comprises hollow projections 13 which point outwards and absorb kinetic energy during deformation. Summary of the Invention

[0007] The present invention is based on the object of providing a protective headgear, wherein the protective headgear comprises a headgear shell and a damping shell, and wherein the damping shell is held operationally securely in a desired position relative to the headgear shell without requiring a material-to-material connection between the damping shell and the headgear shell. Furthermore, the present invention is based on the object of providing a method for producing such a protective headgear.

[0008] This object is achieved by a protective helmet having the features of claim 1 and by a method having the features of claim 11. Advantageous embodiments are described in the dependent claims. Where relevant, advantageous embodiments of the protective helmet according to the invention are also advantages of the method according to the invention, and vice versa.

[0009] The terms "above," "below," "front," and "rear" are used subsequently. These terms refer to the common orientation when a wearer places protective headgear on their head and looks straight ahead.

[0010] Protective headgear according to the present invention comprises a curved headgear shell, a curved damping shell, a retaining ring, and at least one elastic element, optionally a plurality of elastic elements. The damping shell, retaining ring, and the or each elastic element are located within the curved headgear shell. The terms "interior" and "exterior" refer to the space enclosed by the curved headgear shell.

[0011] The retaining ring is fixedly connected to the headgear shell. Preferably, the retaining ring is a complete ring and fully surrounds the head of the wearer of the protective headgear.

[0012] The damping shell is adjacent to the headgear shell and is designed to absorb kinetic energy, in particular kinetic energy acting on the protective headgear from the outside.

[0013] The retaining ring has a circumferential retaining ring edge. The damping shell has a circumferential damping shell edge. The damping shell edge is planarly adjacent to the retaining ring edge. When the protective helmet is placed on the head of a wearer of the protective helmet, the retaining ring edge points upward, and the damping shell edge points downward.

[0014] At least one elastic element is located between the edge of the retaining ring and the edge of the damping shell. The elastic element is supported on the retaining ring, contacts the edge of the damping shell, and serves to move the damping shell away from the retaining ring and presses the headgear shell from the inside. Preferably, multiple elastic elements of the protective headgear have this characteristic.

[0015] The headgear shell protects the wearer of the protective headgear from mechanical and / or thermal and / or chemical environmental influences acting on the protective headgear from the outside. The damping shell is mounted internally to the headgear shell, is protected from environmental influences by the headgear shell, and absorbs kinetic energy acting on the protective headgear from the outside. The headgear shell can be made of a sufficiently strong material, while the damping shell can be made of an elastic and / or plastic material. Because the damping shell is located inside the headgear shell, it does not need to be able to withstand mechanical, thermal, and chemical environmental influences.

[0016] The damping shell receives the kinetic energy that acts on the headgear from the outside, and protects the head of the wearer to a certain extent thus.In addition, the damping shell provides the pad between the headgear shell and the wearer's head.

[0017] According to the present invention, the retaining ring is fixedly connected to the helmet shell. This fixed connection is established at least when the protective headgear is in use / mounted. In one embodiment, it is possible to remove the retaining ring from the helmet shell outside of use, for example, to repair, replace, or clean the retaining ring. Due to the fixed connection, the retaining ring cannot move significantly relative to the helmet shell during use.

[0018] Generally, the damping shell should not change its position relative to the helmet shell, at least when the protective headgear is in use. In particular, neither the damping shell nor the helmet shell should slide back and forth on the wearer's head. Undesirable relative movements can also lead to associated wear and undesirable noises. It will be explained below how and in what manner the present invention contributes to preventing undesirable effects.

[0019] According to the present invention, the circumferential edge of the damping shell is adjacent to the circumferential edge of the retaining ring. The damping shell is located between the retaining ring edge and the helmet shell. Because the retaining ring is fixedly connected to the helmet shell, the retaining ring edge does not change its position relative to the helmet shell. This, of course, eliminates any relative movement that may be caused by tolerances. Therefore, the retaining ring edge limits any possible movement of the damping shell away from the helmet shell.

[0020] According to the present invention, at least one elastic element is supported on a retaining ring fixedly connected to the helmet shell. The elastic element contacts the edge of the damping shell and serves to move the damping shell away from the retaining ring and to press it from the inside toward the helmet shell. Preferably, the protective headgear includes a plurality of elastic elements designed in such a manner that they contact the edge of the damping shell at different points and act together on the damping shell and serve to jointly move it onto the helmet shell.

[0021] The elastic element eliminates the need to connect the damping shell to the retaining ring or the helmet shell. Using one or more elastic elements instead of a fixed connection simplifies finding a suitable material for the helmet shell, retaining ring, and damping shell. Since these three components of protective headgear have different tasks, they are usually made of different materials that are well-suited to the respective tasks.

[0022] According to the present invention, at least one elastic element contacts the edge of the damping shell and contributes to pressing the damping shell against the headgear shell. As a result, the damping shell contacts the edge of the damping shell at at least one connection point, optionally at a plurality of spaced-apart connection points. Planar contact with the damping shell along a longer line segment is not required. The present invention thus reduces the risk of the damping shell being compressed or stretched when the protective headgear is loaded, thereby causing wear or damage.

[0023] Because at least one elastic element presses the damping shell against the helmet shell from the inside, it is not necessary to manufacture the retaining ring precisely according to specifications and to fix it in a precisely defined position relative to the helmet shell. Instead, greater tolerances are possible during the manufacture and assembly of the retaining ring. The elastic element then compensates to a certain extent for inaccuracies in the manufacture and assembly of the protective headgear. In particular, the elastic element can expand to varying degrees and thus still press the damping shell against the helmet shell despite varying possible spacings. Despite these tolerances, the risk of the damping shell performing undesirable movements relative to the helmet shell is relatively low.

[0024] The present invention makes it possible for the damping shell to be mechanically connected neither to the helmet shell nor to the retaining ring. This design simplifies the installation of the helmet shell. Furthermore, in many cases, the present invention makes it easier to remove the damping shell from the protective headgear, for example for cleaning or replacement. In many cases, it is sufficient to compress the or each elastic element (which presses the damping shell against the helmet shell) and remove the damping shell from the helmet shell, since the damping shell is usually made of a flexible material. Furthermore, the design in which the damping shell is not connected to either the helmet shell or the retaining ring reduces the risk of wear on the damping shell. Such wear can occur in protective headgear according to the prior art, in particular at the connection points between the damping shell and the retaining ring, or in the region where the damping shell is materially connected to the helmet shell.

[0025] The present invention eliminates the need for a material-fused connection of the damping shell to the helmet shell or retaining ring. In particular, the need for gluing or securing the damping shell with foam is eliminated. Since no material-fused connection needs to be established, steps are eliminated in the production of the protective helmet according to the present invention compared to the production of protective helmets with material-fused connections. Furthermore, the raw material for the material-fused connection is eliminated. This results in a lighter protective helmet. Solvents for the material-fused connection are also eliminated. Furthermore, the need for heat-resistant raw materials for the material-fused connection is eliminated, which is particularly important when the protective helmet is to be worn in high ambient temperatures. Since the material-fused connection does not need to be loosened, it is easier to remove the damping shell from the protective helmet, for example, to clean it or to replace it with a new one.

[0026] According to the present invention, at least one elastic element is supported on the retaining ring and serves to move the damping shell away from the retaining ring and press it toward the headgear shell. In one embodiment, the elastic element continuously protrudes beyond the edge of the retaining ring. Preferably, the elastic element is located between the edge of the retaining ring and the edge of the damping shell. In another embodiment, the damping shell presses the elastic element into the retaining ring against the spring force, preferably so that the elastic element does not protrude beyond the edge of the retaining ring. In this embodiment, the elastic element also presses the damping shell toward the headgear shell.

[0027] In one embodiment, the retaining ring includes at least one projection that points toward the damping shell. The damping shell includes at least one corresponding recess for each projection. The or each projection of the retaining ring engages in a corresponding recess in the damping shell. Conversely, it is possible for the damping shell to have at least one projection and the retaining ring to have at least one corresponding recess. It is also possible for the damping shell and the retaining ring to each have a recess and a corresponding recess. This embodiment with projections and recesses limits the possible movement of the damping shell relative to the headgear shell in at least one direction and further reduces the risk of the damping shell performing undesirable movements relative to the headgear shell.

[0028] Preferably, the or at least one projection of the retaining ring is located between the headgear shell and the damping shell. Thus, the projection is well protected against mechanical damage.

[0029] In one embodiment, the damping shell has at least one projection. The projection points toward the headgear shell. The headgear shell has at least one corresponding stop element that points toward the damping shell. Alternatively, the headgear shell includes a projection that points toward the damping shell. The damping shell has a corresponding stop element that points toward the headgear shell. In both embodiments, the projection and the stop element together limit movement of the damping shell relative to the headgear shell in one direction, namely, when the projection abuts the stop element. This direction is preferably the viewing direction of a wearer of the protective headgear looking forward.

[0030] Preferably, the outer contour of the curved damping shell, which points toward the headgear shell, is completely or at least partially coordinated with the inner contour of the curved headgear shell, which points toward the damping shell. This design with two coordinated contours helps to hold the damping shell in a desired position relative to the headgear shell. As a result, any possible movement of the damping shell relative to the headgear shell is limited to tangential movements along the curved inner surface of the headgear shell, at least when the protective headgear is positioned on the wearer's head.

[0031] In one embodiment, the retaining ring edge extends in a plane. The retaining ring edge has a region that protrudes from the retaining ring plane, for example, a region that extends in a region plane, wherein the region plane is inclined relative to the retaining ring plane. This protruding region of the retaining ring edge is adjacent to a region of the damping shell edge. The contours of the retaining ring edge and the damping shell edge correspond to one another in at least two adjacent regions. This embodiment also limits the possible movement of the damping shell relative to the headgear shell in at least one direction. In this embodiment, this direction is the viewing direction of a wearer of the protective headgear looking forward.

[0032] In one design, the damping shell has an elongated projection that curves outward, that is, points toward the headgear shell. The headgear shell has a corresponding groove. The elongated projection of the damping shell engages in the groove of the headgear shell. This design limits the possible movement of the damping shell relative to the headgear shell in a direction perpendicular or oblique to the common longitudinal axis of the projection and groove. Preferably, the common longitudinal axis extends parallel to the viewing direction of the wearer of the protective headgear.

[0033] In one embodiment, the edge of the damping shell contacts the edge of the retaining ring along at least a portion of its expansion, and optionally along its entire expansion, i.e., along its entire periphery. In one embodiment, the edge of the damping shell is spaced apart from the edge of the retaining ring along at least a portion of its expansion. It is also possible that the edge of the damping shell is spaced apart from the edge of the retaining ring along its entire expansion, i.e., along its entire periphery. The spacing between the edge of the damping shell and the edge of the retaining ring can remain constant along the edge or vary spatially. The or each elastic element supported on the retaining ring bridges this spacing.

[0034] In a preferred embodiment, the damping shell is not mechanically connected to the helmet shell, in particular not mechanically connected thereto by material fusion. Preferably, the damping shell is also not mechanically connected to the retaining ring. In another embodiment, the damping shell is mechanically connected to the retaining ring at at least one connection point, i.e., preferably releasably connected.

[0035] The retaining ring preferably encompasses the entire head of the wearer of the protective headgear. Preferably, there is a spacing between the retaining ring and the wearer's head, wherein this spacing is dependent on the size and shape of the head. In particular, due to this spacing, the same protective headgear according to the invention, or a plurality of structurally identical protective headgear according to the invention, can be worn by wearers with different head sizes. Furthermore, the same wearer can wear the same protective headgear, optionally with or without a head covering. There is no need to adapt the retaining ring to the shape of the head.

[0036] According to the present invention, the protective headgear includes a retaining ring that is fixedly connected to the helmet shell. Preferably, the protective headgear also includes a support ring, which is also located in the area surrounded by the curved helmet shell. This support ring surrounds the head of the wearer of the protective headgear. The support ring rests at least partially against the wearer's head. A padding or other textile covering may be arranged between the support ring and the wearer's head. Preferably, the textile covering can be removed from the protective headgear and cleaned separately from the rest of the protective headgear.

[0037] There is a distance between the retaining ring and the carrier ring. This distance is generally related to the size and / or shape of the wearer's head. The carrier ring can be made of a flexible material to adapt to the wearer's head shape. Preferably, the length of the carrier ring can be varied, thereby also varying the head width provided by the protective headgear.

[0038] On the one hand, this design provides a retaining ring that helps to hold the damping shell in the desired position relative to the headgear shell and the headgear shell in the desired position relative to the head. Furthermore, the retaining ring can help to hold optional internal equipment. On the other hand, this design provides a supporting ring that helps to keep the protective headgear securely positioned on the wearer's head and allows it to be adapted to the size and shape of the wearer's head.

[0039] A preferred method for manufacturing protective headgear according to the present invention comprises the following steps:

[0040] - providing a helmet shell, a retaining ring, a damping shell and the or each elastic element. These components can be made at different locations and from a material that is well suited to the respective component;

[0041] The or each elastic element is fastened to the retaining ring so that it is supported on the retaining ring and projects beyond an edge of the retaining ring at least in the relaxed state;

[0042] The damping shell is inserted into the interior of the helmet shell. It is possible, but not necessary due to the invention, for the damping shell to be fixed to the helmet shell;

[0043] - The retaining ring is then installed in the headgear shell. After installation, the or each elastic element, which protrudes beyond the edge of the retaining ring, presses the already inserted damping shell against the headgear shell. Optionally, the retaining ring is temporarily held in this position by a human or automated handling device until the retaining ring is fixed to the headgear shell.

[0044] The retaining ring is fixedly connected to the helmet shell. After the fixed connection, the or each elastic element on the retaining ring presses the damping shell toward the helmet shell.

[0045] The manufacturing method is simplified by inserting the damping shell from the inside into the helmet shell and, if necessary, moving the damping shell so that it assumes the desired position relative to the helmet shell. If the inner contour of the helmet shell and the outer contour of the damping shell are coordinated, the damping shell can be inserted into the helmet shell relatively easily, so that no hollow spaces are formed between the helmet shell and the damping shell. The damping shell is preferably inserted into the helmet shell before the retaining ring and the optional supporting ring and the optional internal device are connected to the helmet shell. As a result, neither the retaining ring nor the supporting ring nor the internal device impairs the insertion and correct positioning of the damping shell into the helmet shell.

[0046] By the reverse sequence, the protective headgear can be disassembled again, for example in order to inspect or repair it or to replace damaged components. The invention simplifies the removal of the retaining ring or the supporting ring without having to loosen the connection to the damping shell.

[0047] In one embodiment, at least the damping shell, retaining ring, and the or each elastic element of the protective headgear according to the present invention are produced by at least one 3D printer. Optionally, different components of the protective headgear are also produced by different 3D printers at different locations. In one embodiment, the headgear shell is also produced by a 3D printer, and in another embodiment, by other manufacturing methods. Preferably, these components are assembled to form the protective headgear according to the present invention.

[0048] One aspect of the present invention relates to a 3D printer designed to produce the just-mentioned components of the protective headgear according to the invention. In a further development, an arrangement with a plurality of 3D printers can jointly produce the just-mentioned components.

[0049] In another aspect, the present invention relates to a computer program that can be executed on a computer. If the computer program is executed on a computer, the computer controls at least one 3D printer. The controlled 3D printer produces the components of the protective headgear according to the present invention as just listed. Alternatively, the computer controls multiple 3D printers for different components. It is also possible for different computer programs to control respective computers, and for each controlled computer to produce at least one component of the protective headgear according to the present invention.

[0066] The present invention relates to a protective headgear used by firefighters, police, rescue teams and other operational personnel in order to better protect the head from mechanical, thermal and chemical impacts.

[0067] Like many other protective headgear, this embodiment of the protective headgear comprises a curved headgear shell made of a hard material, a curved damping shell, a load-bearing structure, and internal equipment. The internal equipment rests on the head of the person who wears the protective headgear. This person is hereinafter referred to as the "wearer." The load-bearing structure connects the internal equipment to the headgear shell and is internally fixed to the headgear shell. The internal equipment is omitted in the accompanying drawings.

[0068] The terms "front", "back", "left", "right", "above" and "below" used subsequently refer to the common orientation when a wearer wears protective headgear and looks forward. In some of the figures, the viewing direction BR of a wearer looking straight ahead is drawn.

[0069] The damping shell rests internally against the helmet shell, absorbs kinetic energy acting on the protective helmet from the outside, and provides cushioning for the protective helmet. The damping shell should be located within the helmet shell without significant play. The present invention demonstrates a way to achieve this without requiring a cohesive connection between helmet shell and damping shell, in particular without adhesive or hook-and-loop fasteners.

[0070] Figure 1 、 Figure 2 and Figure 3 The protective headgear 100 is shown from different viewing directions and comprises the following components:

[0071] - a curved helmet shell 2 made of a hard material,

[0072] - a curved damping shell 1 which is inserted into the interior of the helmet shell 2,

[0073] - pivotable face shield 4,

[0074] - a front retaining ring part 3, which is releasably connected to the helmet shell 2 from the inside,

[0075] - a further visor in the form of sunglasses 26 which are arranged between the front retaining ring part 3 and the helmet shell 2,

[0076] - a left screw connection 16.1 and a right screw connection 16.r for releasably connecting the front retaining ring part 3 to a respective functional plate on the outside of the helmet shell 2, wherein the two screw connections 16.1 and 16.r additionally hold the visor 4 pivotably on the helmet shell 2,

[0077] - a left screw connection 5.1 and a right screw connection 5.r, which hold the further visor 26 on the front retaining ring part 3,

[0078] - a front support ring part 6 , which rests on the wearer's forehead and is releasably connected to the front retaining ring part 3 ,

[0079] - a two-part rear support ring part 7 with a left rear part 7.1 and a right rear part 7.r, which rests on the back of the wearer's head,

[0080] - a central rear support ring part 10 in the form of a back-of-the-head support, which likewise rests on the back of the wearer's head and is connected to the two parts 7.1, 7.r of the rear support ring part 7 by means of a respective latching connection,

[0081] - a left retaining arm 8.1 and a right retaining arm 8.r on the front retaining ring part 3,

[0082] - a left retaining arm 9.1 on the left part 7.1 of the rear support ring part 7,

[0083] - right retaining arm 9.r on the right part 7.r of the rear support ring part 7,

[0084] - a latching connection between the two left-hand retaining arms 8.1, 9.1, and

[0085] - A latching connection between the two right-hand holding arms 8.r, 9.r.

[0086] The symbols .l and .r indicate the left or right component.

[0087] The protective headgear 100 additionally comprises an inner device having a textile component that comes into contact with the wearer's scalp. The inner device is omitted in the drawings.

[0088] The outer contour of the damping shell 1 is adapted to the inner contour of the helmet shell 2 .

[0089] The support ring components 6, 7, and 10 form a circumferential support ring that completely surrounds the wearer's head and can be adapted to the wearer's head shape. The retaining ring components 3 and 11 are fixedly attached internally to the helmet shell 2. In one embodiment, a gap exists between the retaining ring component 3 and the support ring component 6. Optionally, a rigid intermediate component 27 bridges this gap. In another embodiment, the support ring component 6 is attached directly to the retaining ring component 3, that is, without the intermediate component 27.

[0090] The support rings 6, 7, 10 should be positioned securely on the wearer's head so that the protective headgear 100 does not slip off the head, and should not press too hard against the wearer's head. Therefore, the wearer can manually change the length of the support rings 6, 7, 10 and thus the head width of the protective headgear 100, i.e., by means of a hand wheel 15 located at the rear of the protective headgear 100. Rotating the hand wheel 15 causes the two parts 7.1 and 7.r to move synchronously away from each other or towards each other.

[0091] exist Figure 4 and Figure 5 In the embodiment, the supporting ring members 6, 7 and 10 and the supports therefor are omitted. Figure 5The additional visor 26 is omitted. The central rear retaining ring component 11 is clearly visible. The rear retaining ring component 11 is arranged between the rear support rings 7 and 10 and the helmet shell 2 and is releasably connected to the helmet shell 2. Its outer contour is adapted to the inner contour of the helmet shell 2. The rear retaining ring component 11 is preferably inherently elastic and, due to its inherent elasticity, presses against the helmet shell 2 from the inside. The rear retaining ring component 11 includes two through-holes 12.1, 12.r, through which two screws 24.1, 24.r are inserted. The screws 24.1, 24.r engage two screw threads 25.1, 25.r within the helmet shell 2 and secure the rear retaining ring component 11 to the helmet shell 2 from the inside. The preferably elastic, preferably centrally arranged, projection 14 presses against the damping shell 1 from below, thereby pressing the damping shell 1 upwards against the helmet shell 2. Within the meaning of the claims, the projection belongs to the spring element.

[0092] exist Figure 6 In the perspective view, the additional visor 26 and the additional damping shell 1 are omitted. Two lateral projections 13.1, 13.r can be seen above the rear retaining ring part 11. The projections 13.1, 13.r rest against the helmet shell 2 from the inside and are located between the helmet shell 2 and the damping shell 1. The damping shell 1 has a downwardly pointing edge. A considerable portion of the front area of ​​this edge is located above the front retaining ring part 3, and the rear area of ​​this edge is located on the projection 14. The two projections 13.1, 13.r grip the damping shell 1 from the outside. As a result, the damping shell 1 is held in its position relative to the helmet shell 2 without the need for a material-fused connection. In particular, adhesive connections and hook-and-loop connections are not required.

[0093] Figure 7 The front retaining ring part 3 is shown in a side view from the left, which has a semi-elliptical shape when viewed from above. The front retaining ring edge K.3 can be seen, which points upward and has an obliquely raised front part K.3v. The front retaining ring edge K.3 is perpendicular to the Figure 7 The front part K.3v protrudes from this plane. In the embodiment, the front part K.3v extends in another plane that is located obliquely on the plane of the front retaining ring edge K.3. The other plane is also perpendicular to Figure 7 Attached plane.

[0094] Figure 8 and Figure 9 In stereoscopic view from two different viewing directions, once from the front ( Figure 8 ) and once from the rear ( Figure 9) shows the rear retaining ring part 11. The upward-pointing rear retaining ring edge K.11, which belongs to the rear retaining ring part 11, can be seen. The front retaining ring edge K.3 and the rear retaining ring edge K.11 together form a circumferential retaining ring edge. In typical use of the protective helmet 100, the circumferential retaining ring edges K.3, K.11 point upward.

[0095] Figure 10 and Figure 11 A first embodiment of the damping shell 1 is shown in two perspective views. Figure 12 and Figure 13 A second embodiment of the damping shell 1 is shown in two perspective views. The damping shell edge K.1 can be seen, ie once from the left ( Figure 11 ), from the inside ( Figure 12 ), and once from the left and from the side ( Figure 13 ) The damping shell edge can be seen. In typical use of protective headgear 100, the damping shell edge K.1 points downward. When the damping shell 1, the front retaining ring part 3, and the rear retaining ring part 11 are arranged inside the helmet shell 7, the downward-pointing damping shell edge K.1 of the damping shell 1 rests on the upward-pointing front retaining ring edge K.3 and the upward-pointing rear retaining ring edge K.11. Furthermore, the following elements of the damping shell 1 can be seen:

[0096] - two lateral recesses 17.1, 17.r on the downwardly pointing damping shell edge K.1, into which two lateral projections 13.1, 13.r on the rear retaining ring part 11 engage,

[0097] a centrally arranged recess 18 on the damping shell edge K. 1 , into which the centrally arranged elastic projection 14 on the rear retaining ring part 11 engages,

[0098] - a front edge region 19 of the damping shell edge K.1, which lies on the front retaining ring edge K.3,

[0099] - an obliquely raised section 19 . v of the front edge region 19 , wherein the section 19 . v lies on the obliquely raised region K. 3 v of the front retaining ring edge K. 3 ,

[0100] - an elongated projection 28 arranged in the middle, and

[0101] - Two serrated edges 20.l, 20.r.

[0102] The headgear shell 2 comprises a centrally arranged groove 29 , into which an elongated projection 28 engages.

[0103] according to Figure 12 and Figure 13 The second embodiment additionally comprises:

[0104] - a centrally located protrusion 21.v at the front, and

[0105] - Rear centrally located projection 21.h.

[0106] In one embodiment, during normal use, a gap exists between the two serrated edges 20.1, 20.r and the two corresponding serrated areas 23.1, 23.r of the front retaining ring edge K.3. Under higher loads, the front edge area 19 moves in the direction of the front retaining ring edge K.3. Only under very high mechanical loads on the protective helmet 100 do the two serrated edges 20.1, 20.r temporarily rest on the serrated areas 23.1, 23.r, thereby dissipating forces. In another embodiment, the two serrated edges 20.1, 20.r permanently rest on the serrated areas 23.1, 23.r.

[0107] Figure 14 and Figure 15 The design of the helmet shell 2 is shown from the inside, which is adapted to the second design of the damping shell 1 ( Figure 12 and Figure 13 ), and can also be compared with the first design ( Figure 10 and Figure 11 ) are used together. Two centrally arranged protrusions 22.v and 22.h can be seen. In this design, the central protrusion 21.v above the damping shell 1 engages in the space between the two protrusions 22.v and 22.h inside the headgear shell 2. The two protrusions 22.v and 22.h each form a stop element for the protrusion 21.v. The stop elements 22.v and 22.h, in conjunction with the protrusion 21.v, limit possible movement of the damping shell 1 relative to the headgear shell 2 in the viewing direction BR and opposite thereto.

[0108] In another embodiment, the projection 21.v of the damping shell 1 rests against the rear projection 22.h of the helmet shell 2. The projection 22.v is a latching connection for the visor 7.

[0109] The upper rear projection 21.h of the damping shell 1 engages in an outwardly directed and centrally arranged groove 29 in the rear region of the helmet shell 2. The projection 21.h thus prevents a movement of the damping shell 1 relative to the helmet shell 2 perpendicularly or obliquely to the viewing direction BR.

[0110] In an alternative design, the helmet shell 2 is matched to the first design of the damping shell 1 ( Figure 10 and Figure 11). Preferably, the helmet shell 2 does not have two Figure 14 and Figure 15 The protrusions 22.v, 22.h are shown in FIG.

[0111] The two serrated areas 20.1, 20.r of the damping shell edge K.1 can be moved in the viewing direction BR up to the serrated areas 23.1, 23.r of the front retaining ring edge K.3 of the front retaining ring part 3. The serrated areas 23.1, 23.r thus form two stop elements that limit the movement of the damping shell 1 relative to the helmet shell 2 in the viewing direction BR. The damping shell 1 only reaches the two stop elements 23.1, 23.r under very high loads.
