    TECHNICAL FIELD OF THE INVENTION
    [001] The invention relates to internal connectors for a protective helmet, particularly for forestry engineers, comprising a support cage, a headband and a neckband that together form a subset of internal connectors that can be fixed on a helmet shell to support and retain the helmet on a user’s head. BACKGROUND OF THE INVENTION
    [002] A protective helmet with internal connectors of this type is known from document DE 8714490 U1. The protective helmet is comprised of a helmet shell and minimal internal connectors. The internal connectors comprise a textile cross strap through which the helmet is worn on the head and which ensures a shock absorbing distance between the head and the helmet shell. In its outer circumference, the helmet is provided with a profusion that covers the side and rear of the helmet and comprises four recesses to support the cross strap at the bottom edge.
    [003] From document DE 10 2004 004 044 B4, a protective helmet that is known comprises a support that serves as internal connectors to support the protective helmet on the head to be protected. Protection is maintained by the support. A head housing is releasably attached to the support or protection. The head wrap serves as the real protection of the skull. As it can be detached from the support or protection, it can be removed in the case of applications in which a situation of danger to the skull, for example, by falling objects, can be excluded. For the user, this means that they can only use the support including the attached protection so that the comfort of using it is enhanced by weight reduction only. In addition, head cooling will be improved. The only advantage here is that the additional safety equipment can be attached to the protection or support when the user is most in need of protection, in addition to skull protection in specific applications (for example, soil compaction work). The support is made of flexible material (leather, elastic plastic material, etc.) to fit the shape of the head. In addition, it is possible to adjust the support in the known way to make it fit in users with different head diameters. The head shell is designed to be cup-shaped so that it can cover the top of the head skull not covered by the shield when the head shell is coupled to the shield or support. Preferably, the head shell is directly coupled to the holder so that the forces acting on the protective helmet, in the event of an impact from objects, can be directly transmitted to the user from the head shell via the holder.
    [004] From document DE 698 11 738 T2, a protective helmet is known in which the internal connectors comprising a subset that contacts the head and including a support cage, a head band, and a neck band are mounted with the aid of a double-walled helmet casing. The headband is made of a flexible material that can readily adjust to the size and shape of the user's head.
    [005] From WO 2005/027671 A1, a safety helmet is known in which a shock absorber unit surrounding the remaining internal connectors is arranged in the helmet shell. Inside the helmet casing, there are protrusions to which the shock absorber unit and the internal connectors are screwable. In this known safety helmet, the shock absorber unit is designed so thick that it is possible to provide a recess on its outer side facing the inside of the helmet in which a transmitter / receiver having a connecting line leading to the outside can be accommodated.
    [006] All the known protective helmets mentioned above have in common that an external force acting on the helmet is essentially transmitted completely to the helmet wearer's head via the internal connectors, particularly via a support cage formed by a crossed strip. That is, the cross strap can only perform a shock absorption function to a certain degree, since it has the additional function of securely holding the helmet on the wearer's head. Consequently, there is also a need for internal connectors for a protective helmet with an improved shock absorption capacity. SUMMARY OF THE INVENTION
    [007] It is the aim of the invention to provide internal connectors of the type mentioned at the beginning and known from the first mentioned document thus designed to provide a protective helmet equipped with an improved shock absorption capacity, regardless of the type of helmet, ie , not just a helmet designed for use in the forest.
    [008] According to the invention, this objective is solved by the support cage being formed of a rigidly flexible elastic material and being provided respectively with a rigid support arm projecting obliquely downwards or backwards in the two areas of the temples as well as in an area at the back of the head for a three-point coupling of the inner connector subset to the helmet shell and to allow for a gap that extends continuously around the inner connector subset within the helmet shell.
    [009] In the internal connectors according to the invention, the support and shock absorption functions are combined in the support cage made of a rigidly flexible elastic material. In fulfilling the shock-absorbing function, the support cage is supported by the helmet shell as the free ends of the arms that project obliquely downward or back support the helmet shell in the support cage so that, in the in the event of an external pressure acting on the top helmet shell, the support arms are subjected to a tensile load by the helmet shell and attempt to form it towards the interior. A protective helmet equipped with the internal connectors according to the invention has a better shock absorption capacity so that less force is transmitted to the user's head.
    [010] The advantageous modalities of the internal connectors according to the invention are the subject of the sub-claims.
    [011] In an embodiment of the internal connectors according to the invention, the support cage is an integrated plastic molding. The shock-absorbing effect of the support cage can be more readily controlled in this way than in the case of the support cage comprised of a textile cross strip as in the prior art.
    [012] In an additional embodiment of the internal connectors according to the invention, the support cage is formed of a plastic material such as polyamide. In this way, the support cage has the required stiffness and is, however, sufficiently elastic for shock absorption.
    [013] In an additional embodiment of the internal connectors according to the invention, the support cage is formed by two pairs of mutually separated support strips that intersect in the center and blend into a single support strip that is peripherally closed at four points connection at its outer ends. In this way, the support cage retains holes large enough for ventilation of the head, but is supported in an area large enough in the head to provide a firm and still comfortable fit of the helmet to the head and to form a sufficiently stable support for the Support.
    [014] In an additional modality of the internal connectors according to the invention, the support arms protrude from the support cage at the connection points. In this way, the support cage forms a support for the support arms in the positions where it is most rigid.
    [015] In an additional embodiment of the internal connectors according to the invention, the support arms are formed integrated in the peripherally closed support strip. In this way, it is ensured that the force is transmitted to the support cage by the support arms along the entire circumference of the support cage, where stress peaks are avoided.
    [016] In an additional modality of the internal connectors according to the invention, the headband is formed integrated in the support cage. In this way, the headband contributes to the reinforcement of the support cage.
    [017] In an additional embodiment of the internal connectors according to the invention, the headband has two ends releasably connected to the free ends of the headband and two free ends releasably connectable to each other in the neck area. In this way, the neck band forms an integrated part of the internal connectors, but can be equipped with additional helmet accessories in the form of a clamping unit in a simple way. For this purpose, the two free ends of the neck strap need only be connected to the clamping unit.
    [018] In an additional embodiment of the internal connectors according to the invention, the neck band is formed from the same material as the support cage. In this way, the production of the internal connectors and the adjustment of their shock absorption capacity are facilitated.
    [019] In an additional modality of the internal connectors according to the invention, the neck band is respectively connected to the support cage between its connections to the head band and its free ends in order to be adjustable in height. In this way, the fit of a protective helmet equipped with the internal connectors according to the invention can be improved in a simple way.
    [020] In an additional embodiment of the internal connectors according to the invention, the support cage comprises two support arms projecting downwards in which the neck band is respectively fixable at a selectable height. As the selectable attachment of the neck strap is performed on support arms that are part of the support cage, the internal connectors remain a self-contained subset regardless of the height at which the neck strap is attached to the support arms.
    [021] In an additional embodiment of the internal connectors according to the invention, the support arms are formed integrated in the support cage. In this way, the stability of the internal connectors as a whole is improved, which, in turn, facilitates the determination of their shock absorption capacity.
    [022] In an additional embodiment of the internal connectors according to the invention, the headband is formed in an integrated manner in the peripherally closed support strip at a distance from the same via the connection strips. In this way, the headband can fulfill the function of supporting the internal connectors on the forehead regardless of the model of the support cage.
    [023] In an additional embodiment of the internal connectors according to the invention, the support arms are further reinforced by integrally formed ribs. In this way, the transmission of force via the support arms is improved.
    [024] In an additional modality of the internal connectors according to the invention, the support arms projecting downwards in the two areas of the temples comprise a device for fixing them in the helmet shell. In this way, the internal connectors according to the invention can be mounted on any helmet. The only precondition is that your helmet shell is provided with complementary fixing devices on the inside or that it comprises slits into which the support arm's projecting downward devices can engage so that the support arms can be subjected to a tensile load through the helmet shell.
    [025] In an additional embodiment of the internal connectors according to the invention, the fixation device is formed so that it can be placed in a positive connection with the helmet shell. It should not be a problem to supply the helmet shell of any type of protective helmet with slots suitable for this purpose as previously during production.
    [026] In an additional embodiment of the internal connectors according to the invention, the support arm projecting backwards in the area at the back of the head comprises a locking device for attachment to the helmet shell. In the simplest case, it is sufficient that the helmet shell has an associated slot in which the support arm projecting backwards can be locked by means of a locking device to be able to transmit a force via the mounting position.
    [027] In an additional embodiment of the internal connectors according to the invention, a device for fixing a chin strap is formed in the support cage. The internal connectors according to the invention enable the chin strap to be directly attached to the support cage due to its inherent rigidity and design. BRIEF DESCRIPTION OF THE DRAWINGS

    [038] According to the illustration in FIGs. 1 to 3 and 7, a subset of internal connectors designated 40 in their entirety comprises a support cage 42, a head band 44, and a neck band 46. The neck band 46 can, according to the representation in FIG. 7, be equipped with a clamping unit designated as 48 as a whole. FIGs. 3 to 5 show a helmet shell 36 prepared for the installation of the internal connector subset 40.
    [039] Three support arms 54, 55 and 56 formed as spacers, support arm 55 not being visible in FIG. 7, serve as devices for a three-point coupling of the internal connectors or the subset of internal connectors 40 to the helmet shell 36. Under the dimensions of the helmet shell 36, the support arms 54, 55 and 56 are dimensioned and arranged so that a gap 60 to accommodate ear protection capsules 35a, 35b and support brackets 37a, 37b of an ear protection 34 shown in FIG. 6 and other helmet accessories, such as the neck strap clamping unit 48 according to FIG. 7 is present between the subset of internal connectors 40 and the helmet shell 36.
    [040] Next, the helmet shell 36, the subset of internal connectors 40 according to the invention, its connection to the helmet shell 36, and then the clamping unit 48 will be described in detail and in that order.
    [041] The helmet shell 36 of a helmet 30 will be described in detail with respect to the drawings, particularly FIGs. 3 to 6, 8 and 9. Helmet shell 36 is not part of the invention. It is just an example of how and where the internal connectors according to the invention can be positioned on an arbitrary helmet selected as an example.
    [042] The helmet shell 36 is formed as an integrated plastic molding. A suitable plastic material for the helmet shell 36 is, for example, ABS. In FIG. 3, the helmet shell 36 equipped with the subset of internal connectors 40 is shown in a longitudinal section view. FIG. 4 shows the helmet shell 36 according to FIG. 3 without the subset of internal connectors 40 in a bottom view. FIG. 5 shows a perspective illustration of the helmet shell according to FIG. 4 in an inclined view from below. On the inner surface of the helmet shell 36, reinforcing ribs extending obliquely 62 are integrally formed in the front and in the central section of the helmet. Transverse to the reinforcement ribs 62 and in the center, a reinforcement rib 64 extending in the longitudinal direction of the protective helmet 30 is formed. The reinforcement ribs 62 and 64 can be seen better in FIGs. 3 and 4. In the central area, the reinforcement ribs 62, 64 follow a slightly recessed area comprising six groups of ventilation holes 52. In the recessed area, a ventilation slide 50 engaging two front guide slots 66 with buttons retainer 68 projecting downward and inward and into two rear guide slits 72 with two retaining buttons 70 is displaceable on the outer surface of helmet shell 36. Ventilation slide 50 has matching ventilation holes located above the ventilation holes 52 in the ventilation position and being moved in the closed position so that the ventilation holes 52 are closed by the ventilation slide 50. The bottom edge of the helmet 30 is laterally directed downwards in the temple area and in the area of the part from behind the head as seen in FIG. 5. The clearance 60 between the subset of internal connectors 40 and the helmet casing 36 mentioned above is thus increased towards the bottom of that area. This facilitates the installation of support devices inside the helmet shell 36 and the accommodation of the ear protection capsules 35a, 35b in the gap 60.
    [043] In the temple area mentioned above, three stem-like profusions 74a or 74b, in which the subset of internal connectors 40 including the support arms 54 or 55 can be mounted in a positive and releasable manner, are integrally formed or otherwise form, supported on each side of the interior of the helmet shell 36. The stem protrusions 74a, 74b can be seen in a side view in FIG. 5, in a plan view in FIG. 4 (on the right side), and in a sectional view in FIG. 8. Stem protrusions 74a, 74b are respectively square domes or hollow profile parts in cross-sectional view, the base section of which is integrally formed inside helmet shell 36. In the area opposite the base section, stem protrusions 74a, 74b are arranged so that they can be freely placed in front of the inner surface of the helmet shell 36. The connection of the stem protrusions 74a and 74b to the interior of the helmet shell 36 and its connection to the helmet shell in the area adjacent to the connection point in a respectively triangular joint is reinforced by additional ribs formed integrally between the stem protrusions 74a, 74b and the helmet shell 36 so that they are substantially rigidly connected to the helmet shell 36. If a force transverse to its longitudinal direction and trying bend the stem protrusions is applied to them, the stem protrusions 74a, 74b try to deform the helmet casing 3 6 accordingly. The purpose of this project is discussed in more detail below together with the description of the installation of the subset of internal connectors 40 in the helmet shell 36.
    [044] At the rear end, the helmet shell 36 is provided with a recess 76 on the lower edge in the center behind which the clamping unit 48 of the neck band 46 is located and thus accessible for manual operation to tighten or release the neck band 46 when helmet 30 is fully assembled.
    [045] To lock the support arm 56 in the helmet housing 36, said housing is provided with a slot 78 in the back area of the head in which the correspondingly formed free end of the support arm 56 (FIG. 2) can engage reliably as seen in FIGs. 7 and 8. When the support arm 56 is engaged, the protrusions 56a, 56b formed on the support arm 56 are located outside of the helmet shell 36 and abut its outer surface so that a tensile load is applied to the support arm 56 when a force acts on the helmet shell 36 above.
    [046] The internal connectors for the protective helmet 30 are described in detail below with respect to the drawings, particularly to FIGs. 1 to 3 and 7. The subset of internal connectors 40 is generally part of a protective helmet that comes into contact with the head and is comprised of the support cage 42, the head band 44 and the neck band 46 equipped with the clamping unit 48. Sub-assembly 40 is mountable to the helmet shell 36 shown in FIGs. 4 and 5 to support and retain helmet 30 on a user's head.
    [047] FIG. 1 shows the subset of internal connectors 40 of the protective helmet 30 in a perspective illustration and an angled view from below. FIG. 2 shows the subset of internal connectors according to FIG. 1 in an inclined top view. FIG. 3 shows a longitudinal sectional view of the subset of internal connectors 40 according to FIG. 1 inserted in the helmet shell 36 of the protective helmet 30 also shown in a longitudinal section view. FIG. 7 shows the subset of internal connectors 40 of the protective helmet 30, two ends of the neck band 46 being releasably connected by the clamping unit 48 in the neck area.
    [048] The support cage 42 is formed of a rigidly flexible elastic material, preferably a plastic material such as polyamide. The support cage 42 is supplied with a rigid support arm 54, 55 or 56 respectively projecting obliquely downwards or backwards in the two areas of the temples, as well as in an area of the back of the head for a three-point coupling in the connectors internal to the helmet shell 36 and to enable the gap 60 to extend continuously around the internal connectors of the helmet shell 36 to accommodate the ear protection capsules 35a, 35b of the ear protection 32 and other helmet accessories. In the embodiment described here, the support cage 42 is produced as an integrated plastic molding. The support cage 42 is formed by two pairs of mutually separated support strips 142, 144 which, according to the representation in FIG. 2, intersect at the center and blend into a single peripherally closed support strip 148 at two lower ends at four connection points 146a, 146b, 146c, 146d. In FIG. 1, the support strip 142, 144 is covered by a cross-shaped piece of padding material 149.
    [049] Support arms 54, 55, 56 protrude from support cage 42 at connection points 146a, 146b, 146c. If the support strips 142 and 144 are assumed to extend in a curve, preferably substantially in a circular arc between the connection points 146a, 146b or 146c, 146d, the support arms 54, 55 or 56 project, respectively , downwards or backwards from the support cage 142 substantially at a tangent to the associated arcs, as can be seen in FIGS. 8 or 2. In the embodiment described here, the support arms 54, 55, 56 are integrally formed in the peripherally closed support strip 148. The headband 44 is integrally formed in the support cage 42 as shown in FIG. 2. The neck strap 46 has two front ends releasably connected to the free rear ends of head band 44, for example, by a plug connection not shown in detail in the figures. The neck strap 46 has, according to the representation in FIGs. 1 to 3, two free ends that can be releasably connected to each other in the neck area, that is, with the aid of the clamping unit 48 as shown in FIG. 7. The neck band 46 can be made of the same material as the support cage 42. The neck band 46 is respectively connected to the support cage 42 between its connections with the head band 44 and its free ends in order to be adjustable. in height, as can be seen, for example, in FIGs. 1 and 2. For this purpose, the support cage 42 comprises two support arms 47a, 47b projecting downwards to which the neck band 46 can be fixed at a selectable height. The neck band 46 has three holes 51 arranged one above the other on each side, which can be engaged with resilient screws projecting from each support arm 47a, 47b, as shown in FIGS. 1 and 2.
    [050] The headband 44 is integrally formed on the peripherally closed support strip 148 via the connecting strips 150 at a distance from the peripherally closed support strip 148. The support arms 54, 55, 56 and the support arms support 47a, 47b are further reinforced by integrally formed ribs 152 or 154.
    [051] The support arms 54, 55 projecting downward in the two areas of the temples comprise a device for fixing inside the helmet shell 36. The device for fixing three through holes 156 or 158 in each of the support arms 54, 55, which can be placed in a positive coupling with the stem protrusions 74a or 74b in the helmet shell 36. The support arm 56 of the support cage 42 projecting backwards in the back area of the head comprises the protrusions 56a , 56b which, as already explained above, form a locking device for releasably securing the subset of internal connectors 40 to the helmet housing 36.
    [052] According to FIG. 2, finally, a device 88a, 88b for mounting a chin strap (not shown) is formed in the support cage 42. The chin strap fixing device 88a, 88b comprises two pivot pins 90a, 90b formed integrally on the strap peripherally closed support 148 of the support cage 42 adjacent to the support arms 54, 55 projecting downwards in the two areas of the temples or, as shown, in an intermediate piece 89a, 89b attachable to the peripherally closed support strip 148.
    [053] In helmets of industrial and forestry engineers, the chin strap is attached to the helmet shell (not shown) or to the support cage 42. In mountaineer helmets, the chin strap is only attached to the helmet shell.
    [054] The mutual connection of the helmet shell 36 and the inner connector subset 40 already partially described above will be discussed in summary and supplemented here with reference to FIGs. 2, 3 and 7. FIG. 2 shows the subset of internal connectors 40 in a perspective illustration and an angled top view. FIG. 3 shows a longitudinal sectional view of the subset of internal connectors 40 inserted in the helmet shell 36 of the protective helmet 30 also shown in a longitudinal sectional view, the clamping unit 48 in the neck band 46 not shown.
    [055] FIG. 8 shows a sectional view of the protective helmet 30 along line VIII-VIII in FIG. 3, the clamping unit 48 is also shown. In FIG. 2, the support arms 55 and 56 formed as spacers can be seen. The second support arm 55 projecting downwards is not visible in FIG. 2. The support arm 55 can be seen in an internal view in FIG. 3. In FIG. 8, the support arms 54 and 55 are shown in a cross-sectional view. For a three-point coupling of the inner connector subset 40 to the helmet shell 36, the rearward-looking support arm 56 is inserted into slot 78 in the helmet shell until protrusions 56a, 56b are locked outside the shell. helmet. The subset of inner connectors 40 is then moved further inward towards the inner surface of helmet shell 36, the support arms 54 and 55 are slid over the stem protrusions 74a or 74b. In the process, through holes 156 and 158 in the support arms 54 and 55 positively accommodate the stem protrusions 74a or 74b, as can be seen in FIG. 8. If the support arms 54, 55 touch the inside of the helmet at the joint between the helmet shell 36 and the stem protrusions 74a, 74b, the connectors 136a and 136b (FIG. 4 and 5) are fitted to the protrusions rod type 74a or 74b to thereby hold support arms 54 and 55 in position. The subset of internal connectors 40 and the helmet shell 36 are now fixedly connected to each other at three points. As soon as the protective helmet 30 is placed on the head and secured to the head with the aid of the clamping unit 48, in addition, a chin strap (not shown) can be attached under the chin, if required. The through holes 156, 158 in the support arms 54, 55 receive, respectively, rod protrusions 74a or 74b in a length at least equal to the internal width of the through holes 156, 158. If a load is applied to the helmet 30 from above , a force is exerted on the support arms 54, 55, 56, and a tensile load is applied to the support arms by the helmet shell 36 supported by the ends of the support arms. A moment trying to deform helmet shell 36 towards the inside at each of the three points on the bottom edge is generated by this force acting on the support arms 54, 55, 56. In this way, helmet shell 36 transforms part of the energy deformation acting on it and thus reduces the effect of force on the person wearing the helmet. The momentum transmission from the support arms 54, 55, 56 to the helmet shell 36 is further enhanced by the support arms being further reinforced by integrally formed ribs 152.
    [056] In the embodiment described above, the support arms 54, 55 are mounted on the helmet housing 36 in a different way than the support arm 56, but this is not necessarily required. The support arms 54, 55 can also be coupled to the helmet shell in the same way as the support arm 56. It is only required that the support arms 54, 55 comprise the same fixation device of the support arm 56 that allows the establishment of a positive engagement of the support arms 54, 55 on the helmet. In that case, the fixing devices for the support arms 54, 55 would also be locking devices to be inserted, for example, into slots in the helmet housing 36 to hold the support arms 54, 55 as well as the support arm 56 in the helmet casing by means of a plug-in connection.
    [057] Next, the ear protection 34 including its support device 80 will be described briefly with reference to FIG. 6. FIG. 6 shows the protective helmet 30, the ear protection 34 shown when articulated over the ears. The ear protection 34 comprises the two ear protection capsules 35a, 35b which are respectively pivotally supported on the fork support bracket 37a, 37b. Helmet shell 36 is provided with fixed ear protection support points 80a, 80b inside it as shown in FIG. 4. The support brackets 37a, 37b supplied with the ear protection capsules 35a or 35b are pivotally supported at the support points 80a, 80b. The ear protection support points 80a, 80b and the support support 37a, 37b are arranged and formed so that the support supports 37a, 37b are articulated between two positions in the clearance 60, and the operating position shown in FIG . 6 in which the earmuffs 35a, 35b cover the ears, and a resting position (not shown) in which the earmuffs 35a, 35b are accommodated in the gap 60 in the helmet housing 35 behind the ears.
    [058] A face shield (not shown) comprises a viewfinder comprising two retaining arms for accommodation of which two connectors 136a, 136b are provided shown in FIG. 5 or 4. A face protection support point 84a or 84b is respectively integrally formed on connectors 136a, 136b as a support device for face protection. The connectors 136a, 136b are fitted to the stem protrusions 74a or 74b, with the face protection support points 84a, 84b resting inside the helmet shell 36 in the temple area.
    [059] Next, the clamping unit 48 already briefly mentioned above will be described in more detail with reference to FIGs. 7 to 9. The clamping unit 48 is, together with the ear protection 34, an additional helmet accessory which, like the ear protection 34, is always positioned within the perimeter of the helmet shell 36 so that the helmet 30 do not have any projecting parts in the area of the clamping unit 48. FIG. 7 shows a side view of the inner connector subset 40 of the protective helmet 30 in which the two ends of the neck strap 46 are releasably connected by the clamping unit 48 in the neck area, the clamping unit 48 is shown in the state pressed in FIG. 7. FIG. 8 shows a cross-sectional view of the protective helmet 30 seen in the rearward direction. FIG. 9 shows a partially broken representation of the protective helmet 30 seen in the forward direction.
    [060] The clamping unit 48 comprises a support 168 in which the free ends of the neck band 46 are inserted on both sides. Support 168 has angled buttons that can be engaged with angled holes 176 of neck band 46. In this way, the length of neck band 46 can be adjusted roughly depending on the size of the head. The adjustment is carried out properly so that the protective helmet 30 can be conveniently placed when the clamping unit is not operated. The tightening of the neck strap 46 after the helmet 30 is fitted will then take place with the aid of the tightening unit 48 as explained below.
    [061] The operation of the clamping unit 148 is carried out by means of a locking tab 174 which, according to FIG. 7, is connected to the support 168 by a joint 173. Between the support 168 and the support housing 172 is located a transfer lever 160, of which only the lower end of a support fork 170 is seen in FIG. 7 which is mounted on the rear face of the support housing 172. The upper end of the support 168 is hingedly connected to the upper end of the transfer lever 169. The support housing 172 is hingedly connected to the lower end of the transfer lever 169 by the support fork 170, these two hinged connections are not shown in detail in FIG. 7. The locking tab 174 is provided inside with a cam supported on the rear face of the transfer lever 169 which is not visible in the drawings. When the locking tab 174 is moved to the closed position shown in FIG. 7 by the action of the meat, the lower end of the support 168 is pivoted backwards. With this articulated movement, the neck band 46 is tightened. In the process, the clamping unit 48 is supported by the support housing 172 at the back of the head in the neck area.
    [062] If the locking tab 174 is pivoted counterclockwise and thus opened, the clamping unit 48 is opened. In this way, the lower edge of the support 168 can be moved towards the support housing 172 so that the neck band 46 is released, and the protective helmet 30 can be put on or taken off. If protective helmet 30 is fitted, locking tab 174 only has to be folded down to secure helmet 30 on the head. This can be conveniently done with one hand and even with a glove. The support housing 172 is covered by a piece of padding material 180 on the front face.
