Description

[0001] protective helmet

[0002] The invention relates to a protective helmet having the features of the preamble of claim 1.

[0003] Safety helmets used by the military, other security forces, firefighters, and other emergency services, as well as in factories and on construction sites, primarily serve to protect the wearer from mechanical injuries, such as those caused by splinters or falling objects. Such helmets typically also feature straps for securing the helmet to the wearer's head.

[0004] Specifically, both front and rear straps are typically provided, which are designed to secure the helmet by lashing. The front straps are attached to the forehead area of ​​the helmet and run essentially vertically downwards, where they are lashed around the wearer's chin. The rear straps are attached to the back of the wearer's head and run more horizontally than vertically. The rear straps are also lashed to the wearer's chin area and are connected to the front straps there. This principle has proven effective for securing the helmet.

[0005] A protective helmet with such a belt system is known from DE 10 2012 000 370 Al from the state of the art.

[0006] The disadvantage of this layout of the front and rear straps, however, is the difficulties that arise when optionally removable ear muffs are to be worn while the protective helmet is being worn. Such ear muffs comprise not only the carrying handle but also two oppositely arranged ear muffs that cover and enclose the ear and the immediately surrounding area. Even if the rear straps are attached very close to the rear end of the protective helmet, their layout towards the chin area, where they are lashed to secure the protective helmet, is such that they intersect with the ear muffs of any ear muffs that are being worn. In such a case, the only options are to either route the rear straps so that they rest on the ear muffs or to route them along one edge of the ear muffs.

[0007] However, both approaches have significant disadvantages. If the straps are routed along one edge of the earmuffs, there's a risk that a rear strap will slip over the earmuffs and thus no longer be secured. On the other hand, if the rear straps are routed over the earmuffs from the outset, they will no longer rest against the head over a significant distance, which can also compromise the secure fit of the helmet.

[0008] In the aforementioned prior art DE 10 2012 000 370 A1, the rear straps are guided over projections on the carrying basket. While this minimally influences the path of the rear straps, it is not sufficient to redirect the rear strap away from the ear area of ​​the head. Furthermore, these projections on the carrying basket are not movable in their position relative to the outer shell, and certainly not freely movable, particularly due to the fixed position of the carrying basket relative to the outer shell.

[0009] Based on this prior art, the object of the invention is therefore to provide a protective helmet which can be used optionally with ear muffs and which also offers a secure fastening option by means of front and rear straps.

[0010] This problem is solved for a protective helmet having the features of the preamble of claim 1 by the features of the characterising part of claim 1.

[0011] Essential to the invention is the finding that a deflection arrangement can be provided which can otherwise be moved relative to the protective helmet and which, by engaging with at least one rear strap, deflects the latter such that it runs at a distance from the ear area of ​​the protective helmet wearer. In this way, ear muffs can optionally be worn with the protective helmet without influencing or impairing the path of the rear strap through the ear muffs. The proposed protective helmet has an outer shell for distributing impact forces and a strap arrangement which has at least one front strap and at least one rear strap, each for lashing to the head of a wearer of the protective helmet. In other words, both the at least one front strap and the at least one rear strap are designed to be lashed, thereby securing the protective helmet to the wearer's head.The protective helmet preferably has two front straps, which are symmetrically attached and lashed with respect to a longitudinal axis of the protective helmet. The front straps can be lashed together using a front buckle of the protective helmet. However, the front straps can also each be lashed with a different structure, such as a chin guard. Likewise, the protective helmet preferably has two rear straps, which are symmetrically attached with respect to a longitudinal axis of the protective helmet. The rear straps are preferably lashed together using a rear buckle of the protective helmet. However, the rear straps can also each be lashed with a different structure.

[0012] According to the proposal, the front fastening points of the protective helmet, to which the at least one front strap is attached, are offset from the rear fastening points of the protective helmet, to which the at least one rear strap is attached, along a longitudinal direction of the protective helmet. The longitudinal direction of the protective helmet corresponds to a viewing direction of the wearer of the protective helmet. The at least one front strap and the at least one rear strap can each be attached directly to the outer shell. However, they can also be attached to other structures, such as head-supporting segments or other support devices of the protective helmet, which in turn are attached directly or indirectly to the outer shell.The fastening can also be variable, for example, in that the at least one front strap and / or the at least one rear strap are attached to a slider, which in turn can be moved along a guide rail. The offset of the fastening points along the longitudinal axis means that the rear fastening points are arranged behind the front fastening points in the longitudinal direction.

[0013] The proposed protective helmet is characterized in that the protective helmet has a deflection arrangement for resting against the head when at least one front strap is tightly fastened and at least one rear strap is tightly fastened, which deflection arrangement is freely movable relative to the outer shell and is configured to engage with the at least one rear strap in such a way that the at least one rear strap is deflected away from an ear region of the head.

[0014] Free mobility, here and in the following, means that the deflection assembly is essentially only loosely connected, directly or indirectly, to the outer shell, for example via an elastic band or rope. This must be distinguished from a connection via a part with only limited elasticity, such as an arm made of a hard plastic, which only allows limited bending and thus no free movement. Free mobility refers to the state in which the straps are not tightly fastened. If at least one front strap and at least one rear strap are each tightly fastened, the deflection assembly is no longer freely movable.

[0015] The deflection arrangement is particularly movable relative to the outer shell if it is connected to the outer shell only via the at least one rear strap and / or the at least one front strap. It can then be moved essentially freely, and its position is only fixed when both the at least one front strap and the at least one rear strap are securely fastened. The deflection arrangement itself or other structures of the protective helmet may be adjustable, and the position of the deflection arrangement when the aforementioned straps are securely fastened also depends on the corresponding settings.

[0016] The deflection of the at least one rear strap away from the ear region of the head means that, compared to the lashed state without a deflection arrangement, the at least one rear strap runs further away from the wearer's ear region in the lashed state with a deflection arrangement. This situation can also be described by the deflection arrangement being configured to engage with the at least one rear strap in such a way that the at least one rear strap runs at a distance from the ear region of the head. The ear region refers in particular to the area on the wearer's head covered by a hearing protection capsule of a capsule-type hearing protector.

[0017] The protective helmet can be a military helmet, a combat helmet, a police helmet, or a pilot's helmet. It can also be a firefighter's helmet, a forestry helmet, or a work safety helmet.

[0018] In principle, the deflection arrangement can only engage with the at least one rear strap. A preferred embodiment of the protective helmet is characterized in that the deflection arrangement is designed to engage with the at least one front strap in such a way that the at least one front strap is deflected away from the ear region of the head. Accordingly, this situation can be described by the deflection arrangement being designed to engage with the at least one front strap in such a way that the at least one front strap runs at a distance from the ear region of the head. In this way, the problems with the earmuffs described above for the rear strap can also be avoided for the at least one front strap. However, it is also possible for the deflection arrangement to engage with the at least one front strap without deflecting it.

[0019] In principle, the deflection arrangement can rest against any desired location on the wearer's head. In particular, the deflection arrangement can be designed to rest against a transversely central chin region of the head. However, a further preferred embodiment of the protective helmet is characterized in that the deflection arrangement has at least one rigid deflection device which rests essentially laterally against the head. In this case, the deflection arrangement can consist of a single deflection device. However, it is preferred that the deflection arrangement has or consists of two rigid deflection devices which rest against the head on opposite sides. In particular, the deflection devices can be arranged at a distance from one another. They are then correspondingly separate deflection devices. In this way, the chin region of the head can remain free, thereby improving wearing comfort.According to a preferred embodiment of the protective helmet, the deflection arrangement comprises a tubular channel. Preferably, the at least one deflection device comprises the tubular channel. Each of the at least one deflection device can also comprise a tubular channel. Furthermore, the at least one rear strap and, alternatively or additionally, the at least one front strap can be passed through the tubular channel. Such guidance through the channel ensures that the front strap or the rear strap is deflected according to the course of the channel.

[0020] In principle, the deflection arrangement and in particular the at least one deflection device can have any desired shape. According to a further preferred embodiment of the protective helmet, the deflection arrangement, preferably the at least one deflection device, is curved in an arc. In particular, the tubular channel can be curved in an arc.

[0021] The curvature of the deflection arrangement, and in particular of the at least one deflection device, can in principle be arbitrary. However, a preferred embodiment of the protective helmet is characterized in that the deflection arrangement, and in particular the at least one deflection device, is concavely curved relative to the ear area. In other words, the curvature extends around the ear area. This ensures deflection away from the ear area.

[0022] In principle, the orientation of the deflection arrangement and the at least one deflection device can be arbitrary. A further preferred embodiment of the protective helmet is characterized in that the deflection arrangement and preferably the at least one deflection device have an orientation in the longitudinal direction. The feature of extension in the longitudinal direction relates to the state of the protective helmet when worn and with the front and rear straps tightly fastened. It means that the orientation has at least a component in the longitudinal direction. An orientation at an angle of 45° to the longitudinal direction would therefore be conceivable, so that the orientation has a component in the longitudinal direction which is the same size as the component in a vertical direction. However, it is also possible for the deflection arrangement and preferably the at least one deflection device to be oriented essentially in the longitudinal direction.This means that the deflection arrangement or the at least one deflection device has an orientation that either corresponds exactly to the longitudinal direction or at least comes closer to it than to another direction such as a transverse or vertical direction.

[0023] The at least one rear strap may be arranged so as to be movable relative to the deflection arrangement, for example, with a loose passage through the channel when not lashed down. However, according to a preferred embodiment of the protective helmet, the at least one rear strap is attached to the deflection arrangement and preferably to the at least one deflection device. It may also be the case that a respective rear strap is attached to a respective deflection device.

[0024] Accordingly, the at least one front strap can also be arranged so as to be movable relative to the deflection arrangement. According to a further preferred embodiment of the protective helmet, the at least one front strap is attached to the deflection arrangement, preferably to the at least one deflection device. Likewise, a respective front strap can be attached to a respective deflection device.

[0025] A preferred embodiment of the protective helmet is characterized in that a front deflection attachment point of the at least one front strap on the deflection arrangement, preferably on the at least one deflection device, is offset in the longitudinal direction from a rear deflection attachment point of the at least one rear strap on the deflection arrangement, in particular on the at least one deflection device. The front deflection attachment point is a point on the deflection arrangement to which at least one front strap is attached. Accordingly, the rear deflection attachment point is a point on the deflection arrangement to which at least one rear strap is attached. In other words, the at least one front strap is attached further forward - relative to the wearer's line of sight - than the at least one rear strap. This means that more distance can be maintained from the ear area.It is possible for the protective helmet to have no further fastening straps besides the at least one front strap and the at least one rear strap. However, a further preferred embodiment of the protective helmet is characterized in that the strap arrangement has at least one chin strap for fastening to a chin region of the wearer's head. Here, it is further preferred that the at least one chin strap is fastened to the deflection arrangement. Likewise, the at least one chin strap can be fastened to the at least one deflection device. It is possible for the chin strap to only run from the wearer's chin to the deflection arrangement and not to be led to the outer shell or near the outer shell at all.

[0026] In principle, in the case of two deflection devices, these can be connected, for example, by the front straps. However, according to a preferred embodiment of the protective helmet, the at least one chin strap connects the two deflection devices. In particular, the at least one chin strap can be arranged at a distance from the outer shell.

[0027] According to a further preferred embodiment of the protective helmet, a chin deflection attachment point of the deflection arrangement is arranged between the front deflection attachment point and the rear deflection attachment point. The chin deflection attachment point is a location on the deflection arrangement to which the at least one chin strap is attached. It is preferred that the chin deflection attachment point is arranged closer to the front deflection attachment point than to the rear deflection attachment point. This allows the rear deflection attachment point to be displaced further toward the back of the head. This, in turn, allows the distance of the rear strap from the ear area to be increased.

[0028] A preferred embodiment of the protective helmet is characterized in that the at least one rear strap is deflected by the deflection arrangement such that the at least one rear strap is guided past a hearing protection capsule of a pair of ear muffs arranged beneath the protective helmet. It is also preferred that the at least one front strap is deflected by the deflection arrangement such that the at least one front strap is guided past a hearing protection capsule of a pair of ear muffs arranged beneath the protective helmet.

[0029] According to a preferred embodiment of the protective helmet, it is provided that the protective helmet has a support arrangement for supporting the protective helmet on the head, that the support arrangement has a front support segment and a rear support segment spaced apart from the front support segment in the longitudinal direction, that the at least one front strap is fastened to the front support segment and the at least one rear strap is fastened to the rear support segment.

[0030] A further preferred embodiment of the protective helmet is characterized in that the protective helmet has a capsule hearing protector with two ear protectors and a carrying handle and that the carrying handle is passed under the outer shell.

[0031] Further advantageous and preferred embodiments will become apparent from the following description with reference to the figures. The drawing, which merely shows exemplary embodiments, shows

[0032] Fig. 1 is a schematic side view from the left of a first embodiment of the proposed protective helmet.

[0033] Fig. 2 is a schematic side view from the right of the proposed protective helmet of Fig. 1, and

[0034] Fig. 2 is a schematic side view from the left of a second embodiment of the proposed protective helmet and

[0035] Fig. 4 is a schematic right side view of the proposed protective helmet of Fig. 3.

[0036] The protective helmet of the first embodiment shown in Fig. 1 and Fig. 2 is a military helmet for army soldiers, which is shown from the left side in Fig. 1 and from the right side in Fig. 2. Two front straps 2 and two rear straps 3 of the strap arrangement 18 are attached to the outer shell 1. Specifically, these are attached to front fastening points 4 and rear fastening points 5, respectively. The protective helmet is essentially symmetrical with respect to a longitudinal direction 6 of the protective helmet. Both the front straps 2 and the rear straps 3 are lashed together at a respective belt buckle.

[0037] The protective helmet has a total of two deflection devices 7, each shaped as a deflection arch and arranged essentially opposite one another. The two deflection devices 7 together form the deflection arrangement 8. The rear straps 3 are guided through the channel, which is also curved in an arc, which the respective deflection device 7 has.

[0038] Because the front straps 2 and the rear straps 3 are tightly lashed, the deflection devices 7 rest laterally against the wearer's head. It can be seen that without the straps being tightly lashed, the deflection devices 7 are freely movable relative to the outer shell 1.

[0039] In addition to the protective helmet, the wearer of the protective helmet also wears earmuffs with a left earmuff 9 and a right earmuff 9. A microphone 17 is attached to the left earmuff 9. The earmuffs 9 each cover an ear area 10 of the head of the wearer of the protective helmet. The concave curvature relative to the ear area 10 causes the rear straps 3 to be guided around the ear area 10. Neither the rear straps 3 nor the front straps 2 touch the earmuffs 9. Without the curved curvature of the channel of the deflection device 7, the rear straps 3 would touch the earmuffs 9.

[0040] The protective helmet of the second embodiment shown in Figs. 3 and 4 is also a military helmet for army soldiers. Like the protective helmet of the first embodiment, the protective helmet of this second embodiment has an outer shell 1, front straps 2 attached to front attachment points 4, and rear straps 3 attached to rear attachment points 5. However, the rear attachment points 5 are not located on the outer shell 1, but rather on the respective rear support segment of a support arrangement 11. The protective helmet of the second embodiment also has oppositely arranged deflection devices 7, which form the deflection arrangement 8. These deflection devices 7 are rigid and curved in an arc, but do not have a channel.

[0041] Furthermore, the deflection devices 7, in the state with the front straps 2 and rear straps 3 lashed down, have an orientation 12 that essentially corresponds to the longitudinal direction 6. Both a front strap 2 and a rear strap 3 are fastened to the deflection devices 7. It can be seen that the front deflection attachment points 13 of the front straps 2 are offset from the rear deflection attachment points 14 of the rear straps 3 with respect to the longitudinal direction 6. In this way, the rear straps 3 can be deflected to such an extent that they avoid the ear area 10 and thus also the ear muffs 9 of the ear muffs. When the rear straps 3 and the front straps 2 are not lashed down, the deflection devices 7 are only connected to the outer shell 1 via these and are therefore freely movable.

[0042] In addition, the protective helmet of the second embodiment has chin straps 15, which are attached to chin deflection attachment points 16 of the deflection devices 7 and which thus connect the deflection devices 7. Together with the front straps 2 and the rear straps 3, the chin straps 15 form the strap assembly 18.
