Description

Technical Field

[0001] The invention relates to a protective helmet having the features of the preamble of claim 1. Background Art

[0002] Protective helmets, which are used by the military, other security forces, fire brigades and other emergency services, and also in factories and construction sites, are primarily intended to protect the wearer from mechanical risks of injury, such as from debris or falling objects. Such protective helmets are also usually provided with straps for attaching the protective helmet to the wearer's head.

[0003] In particular, a front strap and a rear strap are usually provided, which are intended to secure the protective helmet by tightening. The front strap is attached to the front area of ​​the protective helmet and extends generally vertically downwards to be secured in the chin area of ​​the wearer. The rear strap is attached to the back of the wearer's head area and extends more horizontally than vertically. The rear strap is also secured in the chin area of ​​the wearer and is connected to the front strap. This principle has proven to be effective in securing protective helmets.

[0004] In the prior art, DE 10 2012 000 370 A1 discloses a protective helmet having such a belt system.

[0005] However, a disadvantage of this arrangement of front and rear straps is that it is difficult to provide the optional removable earmuffs when the protective helmet is worn. In addition to the support straps, such earmuffs also include two ear cups that are arranged opposite each other and cover and seal the ears and the area around them. Even if the rear straps are fixed very close to the rear end of the protective helmet, their path extending to the chin area for fixing to the protective helmet will intersect with the ear cups of the worn earmuffs. In this case, the only options are to guide the rear straps so that they rest against the ear cups, or to guide them along the edges of the ear cups.

[0006] However, both methods have significant disadvantages. When guided along the edge of the ear cups, there is a risk that the rear straps will slip over the ear cups and no longer be fixed. On the other hand, if the rear straps are guided over the ear cups from the beginning, they will be located at a considerable distance above the head, which will also affect the tight fit of the protective helmet.

[0007] In the above-mentioned prior art DE 10 2012 000 370 A1, the rear strap is guided by projections of the support frame. Although this has a slight influence on the path of the rear strap, this influence is not sufficient to deflect the rear strap away from the ear region of the head. Moreover, these projections of the support frame cannot move in their position relative to the housing, and certainly cannot move freely, especially due to the fixed position of the support frame relative to the housing. Summary of the invention

[0008] Based on this prior art, the object of the present invention is to provide a protective helmet which can optionally be used together with earmuffs and in this case also provides a secure fixation by means of the front and rear straps.

[0009] This object is achieved by a protective helmet having the features of the preamble of claim 1 and the characterizing features of claim 1 .

[0010] A key aspect of the present invention is the discovery that it is possible to provide a deflection device that is movable relative to the protective helmet and that engages with at least one rear strap to deflect it away from the ear region of the wearer of the protective helmet. In this way, the earmuffs can be selectively worn with the protective helmet without interfering with or obstructing the path of the rear strap through the earmuffs.

[0011] The proposed protective helmet has an outer shell for dispersing impact forces and a strap arrangement, which comprises at least one front strap and at least one rear strap, each for fixing to the head of the wearer of the protective helmet. In other words, the at least one front strap and the at least one rear strap are configured to be fixed so as to fix the protective helmet to the head of the wearer. The protective helmet preferably has two front straps, which are fastened symmetrically relative to the longitudinal axis of the protective helmet and are thereby fixed. The front straps can be fixed together by the front buckles of the protective helmet. However, the front straps can also be fixed to another structure, such as the chin part, respectively. The protective helmet also preferably has two rear straps, which are fixed symmetrically relative to the longitudinal axis of the protective helmet. The rear straps are preferably fixed to each other by the rear buckles of the protective helmet. However, the rear straps can also be fixed to another structure, respectively.

[0012] According to the invention, the front fixing position of the protective helmet, where at least one front strap is fixed, is offset in the longitudinal direction of the protective helmet relative to the rear fixing position of the protective helmet, where at least one rear strap is fixed. The longitudinal direction of the protective helmet corresponds to the line of sight of the wearer of the protective helmet. At least one front strap and at least one rear strap can each be directly attached to the shell. However, they can also be attached to other structures, such as a head support segment or other supporting devices of the protective helmet, which are themselves directly or indirectly attached to the shell. The fixing can also be variable, for example, at least one front strap and / or at least one rear strap are attached to a slider, which in turn can be moved along a guide rail. The offset of the fixing position along the longitudinal axis means that the rear fixing position is located behind the front fixing position relative to the longitudinal direction.

[0013] The proposed protective helmet is characterized in that the protective helmet has a deflection device for resting against the head when the at least one front strap and the at least one rear strap are fixed, the deflection device being connected to the shell so as to be freely movable relative to the shell and being configured to engage with the at least one rear strap to deflect the at least one rear strap away from the ear area of ​​the head.

[0014] Here and below, freely movable means that the deflection device is in principle at most loosely connected to the housing directly or indirectly, for example, via elastic straps or cables. This should be distinguished from a connection via components that are only slightly elastic, such as arms made of hard plastic material, which only allow a limited degree of bending and are therefore not freely movable. Freely movable refers to the state when the straps are not fixed. When the at least one front strap and the at least one rear strap, respectively, are fixed, the deflection device is no longer freely movable.

[0015] In particular, if the deflector is connected to the outer shell only via at least one rear strap and / or at least one front strap, the deflector is movable relative to the outer shell. It can then be substantially freely movable, its position being fixed only when both the at least one front strap and the at least one rear strap are fixed. The deflector itself or other structures of the protective helmet are adjustable, the position of the deflector also depending on the corresponding setting when said straps are fixed.

[0016] The deflection of the at least one rear strap away from the ear region of the head means that, in the fixed state with the deflection device, the at least one rear strap extends away from the ear region of the wearer compared to the fixed state without the deflection device. This can also be described as the deflection device being configured to engage with the at least one rear strap so that the at least one rear strap extends at a distance away from the ear region of the head. In particular, the ear region refers to the area of ​​the wearer's head covered by the ear cup of the earmuff.

[0017] In particular, the protective helmet can be a military helmet, a combat helmet, a police helmet or a pilot's helmet. Likewise, the helmet can be a fire helmet, a forestry helmet or a work safety helmet.

[0018] In principle, the deflection device can only engage with the at least one rear strap. A preferred embodiment of the protective helmet is characterized in that the deflection device is configured to engage with the at least one front strap so as to deflect the at least one front strap away from the ear region of the head. Therefore, this situation can also be described as the deflection device being configured to engage with the at least one front strap so as to extend at a distance away from the ear region of the head. In this way, the above-mentioned problems with rear straps and earmuffs can also be avoided for the at least one front strap and earmuffs. However, the deflection device can also engage with the at least one front strap without deflecting it.

[0019] In principle, the deflection device can be placed at any position on the wearer's head. In particular, the deflection device can be configured to rest against a chin area laterally centered on the head. However, another preferred embodiment of the protective helmet is characterized in that the deflection device has at least one rigid deflection device, which rests essentially on one side of the head. The deflection device can consist of a single deflection device. However, preferably, the deflection device has or consists of two rigid deflection devices, which rest on opposite sides of the head. In particular, the deflection devices can be arranged at a distance from each other. These are respective independent deflection devices. In this way, the chin area of ​​the head can remain free, thereby increasing the comfort of the wearer.

[0020] According to a preferred embodiment of the protective helmet, the deflection device has a tubular channel. At least one deflection device preferably has a tubular channel. Each at least one deflection device may also have a tubular channel. In addition, at least one rear strap and / or at least one front strap may be guided through the tubular channel. This guidance through the channel ensures that the front strap or rear strap is deflected along the path of the channel.

[0021] In principle, the deflection device, in particular the at least one deflection device, can have any shape. According to another preferred embodiment of the protective helmet, the deflection device, preferably the at least one deflection device, is curved in an arc. In particular, the tubular channel can be curved in an arc.

[0022] The curvature of the deflection device, in particular 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 device, in particular the at least one deflection device, is curved concavely with respect to the ear region. In other words, the curvature surrounds the ear region. This ensures a deflection away from the ear region.

[0023] In principle, the orientation of the deflection device and of the at least one deflection device can also be arbitrary. Another preferred embodiment of the protective helmet is characterized in that the deflection device, preferably at least one deflection device, has an orientation in the longitudinal direction. The extension characteristics in the longitudinal direction are related to the state when the protective helmet is worn and the front and rear straps are fixed. This means that the orientation has at least one part in the longitudinal direction. Thus, an orientation at an angle of 45° to the longitudinal direction can be envisaged, so that the component of the orientation in the longitudinal direction is the same as the component in the vertical direction. However, the deflection device, preferably at least one deflection device, can also be oriented essentially in the longitudinal direction. This means that the orientation of the deflection device or at least one deflection device either corresponds completely to the longitudinal direction or is at least closer to the longitudinal direction than other directions, such as the transverse or vertical directions.

[0024] At least one rear strap can be arranged to be movable relative to the deflection device, for example to be loosely passed through the channel in an unsecured state. However, according to a preferred embodiment of the protective helmet, at least one rear strap is attached to the deflection device, preferably to at least one deflection device. A respective rear strap can also be attached to a respective deflection device.

[0025] Accordingly, at least one front strap can also be moved relative to the deflection device. According to another preferred embodiment of the protective helmet, at least one front strap is attached to the deflection device, preferably to at least one deflection device. A respective front strap can also be attached to a respective deflection device.

[0026] A preferred embodiment of the protective helmet is characterized in that at least one front strap is fixed to the deflection device, preferably to a front deflection fixing point on the at least one deflection device, offset with respect to the longitudinal direction relative to the rear deflection fixing point of at least one rear strap on the deflection device, in particular on the at least one deflection device. The front deflection fixing point is the point on the deflection device to which the at least one front strap is fixed. Correspondingly, the rear deflection fixing point is the point on the deflection device to which the at least one rear strap is fixed. In other words, with respect to the wearer's line of sight, the at least one front strap is then fixed further in front of the at least one rear strap. This means that a greater distance to the ear area can be maintained.

[0027] The protective helmet may be such that, apart from the at least one front strap and the at least one rear strap, it has no further fastening straps. However, another preferred embodiment of the protective helmet is characterized in that the strap arrangement has at least one chin strap for fastening to the chin area of ​​the wearer's head. Here, it is further preferred that the at least one chin strap is attached to the deflection device. Likewise, the at least one chin strap may be attached to the at least one deflection device. The chin strap may extend only from the wearer's chin to the deflection device, without being guided at all to the housing or close to the housing.

[0028] In principle, if there are two deflection devices, for example, they can be connected by a front strap. However, according to a preferred embodiment of the protective helmet, 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.

[0029] According to another preferred embodiment of the protective helmet, the chin deflection fixing point of the deflection device is arranged between the front deflection fixing point and the rear deflection fixing point. The chin deflection fixing point is the point on the deflection device to which at least one chin strap is fixed. Preferably, the chin deflection fixing point is arranged closer to the front deflection fixing point than the rear deflection fixing point. This allows the rear deflection fixing point to be moved further towards the back of the head. This in turn increases the distance between the rear strap and the ear area.

[0030] A preferred embodiment of the protective helmet is characterized in that at least one rear strap is deflected by a deflection device so that the at least one rear strap is guided past an ear cup of an earmuff arranged under the protective helmet. It is also preferred that at least one front strap is deflected by a deflection device so that the at least one front strap is guided past an ear cup of an earmuff arranged under the protective helmet.

[0031] According to a preferred embodiment of the protective helmet, the protective helmet has a supporting device for supporting the protective helmet on the head, the supporting device has a front supporting section and a rear supporting section spaced apart from the front supporting section in the longitudinal direction, at least one front strap is fixed to the front supporting section, and at least one rear strap is fixed to the rear supporting section.

[0032] Another preferred embodiment of the protective helmet is characterized in that the protective helmet has earmuffs with two ear cups and a support strap, and that the support strap is passed under the outer shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Further advantages and preferred embodiments will be apparent from the following description in conjunction with the accompanying drawings. In the drawings, only exemplary embodiments are shown:

[0034] Figure 1 is a schematic diagram on the left of a first exemplary embodiment of the proposed protective helmet,

[0035] Figure 2 yes Figure 1 The right schematic diagram of the proposed protective helmet is shown in

[0036] Figure 3 is a schematic diagram on the left of a second exemplary embodiment of the proposed protective helmet,

[0037] Figure 4 yes Figure 3 The right schematic diagram of the proposed protective helmet is shown in FIG. DETAILED DESCRIPTION

[0038] Figure 1 and Figure 2 The protective helmet of the first exemplary embodiment shown in FIG. 1 is a military helmet for soldiers. Figure 1 is displayed from the left and Figure 2 Attached to the outer shell 1 are two front straps 2 and two rear straps 3 of a strap arrangement 18. In particular, they are attached at a front fastening location 4 or a rear fastening location 5. The protective helmet is visually substantially symmetrical with respect to the longitudinal direction 6 of the protective helmet. The front straps 2 and the rear straps 3 are each fastened together at a buckle.

[0039] The protective helmet has a total of two deflection devices 7, each formed as a deflection arc and arranged approximately opposite each other. The two deflection devices 7 together form a deflection device 8. The rear belt 3 is guided through a channel that is also curved in an arc shape and that the corresponding deflection device 7 has.

[0040] The fixing of the front strap 2 and the rear strap 3 means that the deflection device 7 rests against one side of the wearer's head. It can be seen that the deflection device 7 is free to move relative to the housing 1 without fixing the straps.

[0041] In addition to the protective helmet, the wearer of the protective helmet also wears earmuffs with a left ear cup 9 and a right ear cup 9. A microphone 17 is attached to the left ear cup 9. The ear cups 9 each cover an ear region 10 of the head of the wearer of the protective helmet. The concave curvature relative to the ear region 10 means that the rear band 3 is guided around the ear region 10. Neither the rear band 3 nor the front band 3 touches the ear cup 9. Without the arc curvature of the channel of the deflection device 7, the rear band 3 would have brushed the ear cup 9.

[0042] Figure 3 and 4 The protective helmet of the second exemplary embodiment shown in is also a military helmet for soldiers. Like the protective helmet of the first exemplary embodiment, the protective helmet of the second exemplary embodiment has an outer shell 1, a front strap 2 attached to a front fixing location 4, and a rear strap 3 attached to a rear fixing location 5. However, the rear fixing location 5 is not on the outer shell 1, but on a corresponding rear support section of the support device 11.

[0043] The protective helmet of the second exemplary embodiment also has deflection devices 7 arranged opposite one another, which form a deflection arrangement 8. These deflection devices 7 are rigid, curved in an arc, but without channels.

[0044] Furthermore, in the state in which the front band 2 and the rear band 3 are fixed, the deflection device 7 has an orientation 12 which corresponds substantially to the longitudinal direction 6. Here, the respective front band 2 and the respective rear band 3 are fixed to the deflection device 7. It can be seen that the front deflection fixing point 13 of the front band 2 is offset with respect to the rear deflection fixing point 14 of the rear band 3 with respect to the longitudinal direction 6. In this way, the rear band 3 can be deflected to a sufficient extent to avoid the ear region 10 and thus also the ear cup 9 of the earmuff. When the rear band 3 and the front band 2 are not fixed, the deflection device 7 is connected to the housing 1 only via these bands and can therefore move freely.

[0045] Furthermore, the protective helmet of the second exemplary embodiment has a chin strap 15 which is fastened to a chin deflection fastening point 16 of the deflection device 7 and in this way connects the deflection device 7. Together with the front strap 2 and the rear strap 3, the chin strap 15 forms a strap arrangement 18.
