Description

Hard hat and method of using such

The invention relates to a protective helmet, in particular for motorcyclists, according to the preamble of claim 1. Furthermore, the invention relates to a method for using a protective helmet according to the independent claim. 9

In most countries, wearing a safety helmet is for motorcyclists

mandatory, as they are exposed to drivers of the passenger cars particularly high risks. In particular, a risk in a traffic accident to carry a particularly serious head injury is particularly high. A helmet wearer is to be understood in the following to mean a human person who has arranged a protective helmet in the intended manner on or around the wearer's head. Anatomical location herein refers to a healthy human. In order to be able to develop its protective function particularly efficiently, the protective helmet rests directly against a head of the helmet wearer or motorcyclist. However, this raises the problem that the hard hat from an injured helmet wearer by means of a first-aid is only particularly difficult to remove. In order to make it particularly easy to remove the protective helmet from a crashed helmet carrier, solutions are already known.

Thus, EP 1 854 368 A2 discloses a protective helmet, in particular for motorcyclists, with a helmet shell forming a head-receiving region, which has an opening facing a shoulder region of a helmet wearer. Furthermore, the protective helmet comprises a protection unit arranged within the head receiving region, which directly adjoins the helmet shell and on which at least one first fastening element is arranged. In addition, one is within the head receiving area

arranged cushion unit provided which bears directly against a head of the helmet wearer and to which at least a second fastening element is arranged, which in a plug connection direction releasably connected to the corresponding first

Fastener is connectable. Furthermore, the protective helmet has a removal unit, via which the first and the second fastening element can be detached from one another. When removing the padding unit from such a conventional protective helmet, while it is arranged around the head of the helmet wearer, a pressure is exerted, at least briefly, on the head of the helmet wearer, since the first and the second

Fastening element against the connector connection direction are to be solved from each other. Usually, the plug connection direction of the two fastening elements is oriented at least substantially perpendicularly or at least substantially radially relative to the head of the helmet wearer. Accordingly, there is a need to be able to remove the helmet from a crashed helmet wearer particularly easy or gentle, in particular to any injury, for example

Head injury and / or spinal injury, not aggravated by removing the helmet.

It is an object of the invention to provide a conventional protective helmet in such a way

develop further that this is particularly gently removable from a head of a helmet wearer. This object is achieved by a protective helmet with the features of claim 1. Furthermore, a method for using such a protective helmet is to be provided, by means of which the protective helmet is removed from the helmet wearer's head in a particularly gentle manner. This task will

According to the invention by a method for using a protective helmet with the

Characteristics of claim 9 solved.

Advantageous embodiments of the invention are the subject of the dependent

Claims and the description. Advantages and advantageous embodiments of the protective helmet according to the invention are to be regarded as advantages and advantageous embodiments of the method according to the invention for the use of the protective helmet and vice versa.

So in order to develop a conventional protective helmet so that it is particularly gently removed from the head of the helmet wearer, it is according to the invention

provided that the first and the second fastening element and consequently the protective unit and the cushion unit each at least partially by means of

Removal unit along a direction transverse to the connector direction oriented

Release direction of each other are solvable. This means that a medial movement, that is to say a movement directed toward an imaginary head or skull center, at least essentially, ideally completely eliminates the cushion unit. There may be a plurality of each of a first and a second fastener fastener pairs provided on the helmet to the upholstery unit and releasably connect the protection unit with each other. As a result, the upholstery unit and the protection unit are arranged relative to each other in a particularly stable position, so that it is ensured that the helmet shell performs no unwanted movements on the head of the helmet wearer and fits tight as desired.

In the case of an injured helmet wearer or motorcyclist, especially if this is not responsive, it is therefore possible for the first responder to remove the helmet from the head of the helmet wearer or remove, without the motorcyclist or

To expose the helmet wearer to a risk of further aggravating any head injury.

Is by means of the removal unit, the cushion unit at least partially - for example, only a padding element or more padding elements of the padding unit - detached from the protection unit and removed from the head receiving area of the helmet, the helmet shell, together with the remaining protection unit and a possibly existing remaining padding unit is particularly gentle or easy to remove from the head of the injured helmet wearer. It is considered to be particularly gentle and safe when the helmet is removed in a cranial direction from the head of the helmet wearer, which, due to a prior removal of the cushion unit - or at least one cushioning element - is executable using only a particularly small amount of force.

It has proved to be advantageous if one of the fastening elements has a push button and the other of the fastening elements has a push-button receptacle which has a part of the extraction unit designed as a slot opening the push-button receptacle laterally. That means the first one

Fastening element may be formed as the push button, when the second fastening element is designed as the push button receptacle. Accordingly, the first fastener may be formed as the push button receptacle when the second fastener is formed as the push button. In any case, the push-button receptacle on the slot which is adapted to release the push button from the push-button receptacle when the cushion unit and the protection unit slide in the release direction of each other. The particularly gentle from the head of the injured helmet wearer removable hard hat is particularly easy or low effort to produce when the two corresponding fasteners form such a push-button-button connection, the slot is part of the removal unit. In addition, the removal unit is due to a special simple structure, in particular without moving parts, particularly susceptible to incorrect operation, wear and / or damage.

It has also been found to be advantageous that the release direction extends at least substantially parallel to a longitudinal axis of the head of the helmet wearer. The longitudinal axis of a human body, such as the helmet wearer, is a cut line formed by a frontal plane along with a perpendicularly intersecting sagittal plane of the body. In particular, the release direction, starting from the head of the helmet wearer in the direction of a torso, toward a foot of the helmet wearer, that is, caudally aligned. In other words, it is provided that although the upholstery unit starting from the head of the helmet wearer downwards, the protective helmet, however, starting from the head upwards, that is, cranial, is removed. In this way, when removing the helmet from an injured and / or unconscious helmet wearer ensures that this is removed by removing the helmet no injury or any injury is not aggravated. For when removing the helmet in the cranial direction, a spine of the helmet wearer can at least substantially stretched and / or remain in their current position.

So that a first responder can remove the upholstery unit from the protective helmet of the injured helmet wearer in a particularly simple manner, the removal unit can have a pulling element by means of which the upholstery unit can be withdrawn from the head receiving region in the release direction, ie, caudally. For the first responder, it is thus possible in a particularly simple manner to pull the padding unit out of the head receiving region of the protective helmet in a particularly easy manner via the tension element in the release direction. It is the first responder or the person who pulls the upholstery unit from the protective helmet or from the head receiving area, by means of

Pulling a particularly easy-to-grip handle for manipulating the padding unit or the or from the head receiving area to be removed padding provided.

It can further be provided that the removal unit has at least one recess extending parallel to the release direction in the protection unit. In particular, these depressions correspond in their dimensions at least substantially dimensions, such as a diameter, of the push button, so that it can slide in a withdrawal of the cushion unit from the head receiving portion in the recesses. Ideally, each first fastener or every second Attachment each associated with a recess in the protection unit.

In particular, this respective depression can be placed over the slot in the

Open the push-button receptacle, so that the push-button engages over the slot in the respective recess when it comes out of the push-button receptacle. The recess may be provided on parts or portions of the protection unit, which are particularly stable and / or resistant to deformation, for example, tearing, etc., are formed. This means that the recess allows the first responder to easily separate the padding unit from the guard unit without having to exert a force for destroying or breaking the particularly resistant sections. An end of the recess remote from the push-button receptacle can open into a lower edge of the protective unit, which can at the same time form a lower edge of the protective helmet so that the push-button sliding in the recess can slide out of the protective unit unhindered. In other words, the recess may extend through a Styrofoam portion of the protection unit to the first responder the

Remove the padding unit even further simplify.

In the event that the at least one push-button receptacle is arranged on the cushion unit, at least one such depression may be provided on the cushion unit in an analogous manner, but its end remote from the push-button receptacle is then rotated by 180 degrees, that is to say into an upper edge of the cushion

Upholstery unit or the upholstery element opens. By means of this at least one

Recess ensures that the upholstery unit or the upholstery element and the protection unit can easily slide off each other when pulling out the upholstery unit or the upholstery element, wherein the first or the second fastening element is not hindered by the particularly rigid protection unit.

Furthermore, the first fastening element can have a retaining element which completely penetrates the protective element and an attachment element which holds the fastening part on a side of the protective helmet facing away from the head of the helmet wearer. As a result, the first fastening element can be connected in a particularly simple manner and with little effort to a protective element main body of the protective unit. It can be provided, for example, that the elongate attachment portion a

Tooth structure has, which corresponds at least substantially with a staple structure of the holding element. For example, the attachment portion may be attached to or connected to the push-button receptacle of the first fastener such that the attachment portion extends through and beyond the protection member. When mounting the first fastener extends Accordingly, the attachment portion through the arranged on the side facing away from the head of the helmet wearer side support elements, so that by means of a

Interaction between the tooth structure and the staple structure of the

Fastening portion is locked against movement in the direction of the head of the helmet wearer out. In other words, the protective element base body is in each case arranged directly between the retaining element and the push button receptacle.

It is particularly advantageous if the cushion unit in each case at least one

Upholstery element for a left cheek and for a right cheek comprises. In other words, the padding unit may comprise a plurality of padding elements, one on the left cheek of the helmet wearer and another on the right cheek of the helmet

Helmet carrier rests. Furthermore, further upholstery elements of the upholstery unit can be provided, which rest against further regions of the head of the helmet wearer in order to allow the helmet wearer a particularly comfortable wearing feeling when the protective helmet is attached. In particular, the left cheek pad member and the right cheek pad member may be connected to each other, for example via an arcuate cam member, so that the pad members are particularly easily positionable in the head receiving portion.

The protective helmet can be designed as a flip-up helmet. This means that the helmet shell can be formed by a front and a pivotally connected, rear shell element. Such a flip-up helmet is considered particularly comfortable because, for example, a chin guard can be opened, so that a face of the

Helmet carrier is released without having to remove the flip-up helmet completely from the head. In order not to hinder a folding function of the protective helmet, the protective unit and the padding unit can each be segmented, that is, each have a plurality of protective or upholstery elements.

Furthermore, the invention relates to a method for using a protective helmet, in particular for motorcyclists, with a head shell forming a helmet shell, which has a shoulder region of a helmet wearer facing opening; with a protection unit arranged within the head receiving region, which directly adjoins the helmet shell and on which at least one first fastening element is arranged; and with a cushion unit arranged within the head receiving region, which rests directly on a head of the helmet wearer and on which at least one second fastening element is arranged. In the method, the first and the corresponding second fastening element in a Plug connection direction releasably connected to each other and in an emergency over a

Removal unit detached from each other. In order to remove the protective helmet from the head of the helmet wearer in a particularly gentle manner, it is provided according to the invention that the first and the second fastening element and consequently the protective unit and the upholstery unit are detached from one another by means of the removal unit along a release direction oriented transversely to the connector direction.

The elements described in connection with this method and / or

Features correspond in shape and function respectively to the elements and / or features described in connection with the protective helmet, so that a renewed description of these elements / features is omitted herein.

An emergency in connection with the method or in connection with the protective helmet is a situation in which the helmet wearer is unable to consciously determine whether the protective helmet should be removed from his head. This is especially the case when the shirt wearer is a crashed motorcyclist who is unconscious after having been involved in a traffic accident. A first responder who provides first aid to the injured motorcyclist is now faced with the task of removing the protective helmet from the motorcyclist's head in order to carry out further measures in the context of first aid. For this purpose, the protective unit and the padding unit are at least partially detached from each other by these along the release direction, which runs parallel to a longitudinal axis of the motorcyclist and a shoulder region of the motorcyclist faces, are detached from each other. In other words, the first responder can pull the padding unit or parts of the padding unit, for example one or more upholstery elements, out of the head-receiving area of the protective helmet, so that subsequently the rest of the protective helmet, which is bounded by the outer helmet shell, upwards means in cranial direction, can be removed from the head of the injured motorcyclist. In this way, it is particularly advantageous to ensure that the first responder to remove the helmet from the head of the motorcyclist, the head of the rider does not have to move excessively, whereby a risk of hurting the rider is thereby particularly low.

A protective helmet according to the invention and a method according to the invention in each case lead to an inhibition threshold for first responders to help an accident victim sink. Because the first responders do not have to worry about injuring the motorcyclist when removing the helmet or even further to any existing injury worsen. Therefore, the protective helmet and the method presented herein are particularly suitable for further promoting first aid measures in road traffic, whereby the consequences of an accident can be alleviated.

Further features of the invention will become apparent from the claims, the figures and the description of the figures. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures are not only in the respectively indicated combination, but also in others

Combinations or used alone.

The invention will now be explained in more detail with reference to a preferred embodiment and with reference to the drawings. It shows:

Fig. 7 in a perspective view of the applied to a head of a helmet wearer helmet looking towards a chin of the helmet wearer.

Fig. 1 and Fig. 2 each show a schematic representation of a along a

Sectionally cut protective helmet 1, wherein the sectional plane in Fig. 1 a

Sagittal and in Fig. 2 is a frontal plane of a human body. The protective helmet 1 has a helmet shell 2 which forms or surrounds a head receiving region 3. In other words, the helmet shell 2 is adapted to a head 4 (see FIG. 6) of a helmet carrier 5 (for reasons of clarity only shown in FIG. 6). to absorb or at least substantially completely cover up. For this purpose, the protective helmet 1 has a shoulder area 6 (see FIG. 6) facing the opening 7, via which the protective helmet 1 can be plugged or placed on the head 4 of the helmet carrier 5.

In order for the protective helmet 1 to be able to deploy its intended protective effect in a particularly efficient manner, the head receiving region 3 is at least substantially completely lined by a protective unit 8. Such a protection unit is already well known in the prior art and will only be described roughly herein. The protection unit 8 is usually made of a plastic and adapted to reduce in a collision of the protective helmet 1, in particular in a traffic accident, an externally acting on the helmet 1 force in which the protection unit 8 under a defined deformation of itself receives the force , This ensures that a head injury of the helmet wearer 5 is particularly mild or ideally completely avoided.

It is further necessary that the protective helmet 1 rests particularly close to the head 4 of the helmet carrier 5. In order to design a wearing comfort as advantageous as possible, a padding unit 9 is also provided within the head receiving portion 3, which rests directly on the head 4 of the helmet wearer 5 with attached protective helmet 1. This means that between the helmet shell 2 and the cushion unit 9, the protection unit 8 is arranged. In particular, the protection unit 8 in the interior of the helmet shell 2, that is in the head receiving area 3, force, form and / or cohesively secured to an inner side of the helmet shell 2.

In a helmet designed as a flip-up helmet 1 whose helmet shell is formed by a front and a pivotally connected thereto, for example via a hinge, rear shell element. Therefore, the protection unit 8 can be subdivided or segmented so that the protection unit 8 is composed of a plurality of protective elements 10 (see FIG. 3). In an analogous manner, the cushion unit 9 can be replaced by several

Padding elements 1 1 (see Fig. 4) to be assembled. In particular, a right padding element 1 1 for a right cheek of the helmet wearer 5 and a left

Padding element 1 1 may be provided for a left cheek of the helmet wearer. In addition, further, not described in detail herein padding elements 11 may be present in the protective helmet 1, which, for example, adjacent to an occiput of the helmet carrier 5. Separating points, by means of which the cushion unit 9 in the individual

Padding elements 1 1 is segmented, in particular may be such that one of Opening 7 facing padding element 1 1 or more of the opening 7 facing padding elements 11 can be removed from the head receiving portion 3 of the protective helmet 1, wherein other padding elements 11, for example, provided for the back of the head cushion elements 11 may remain in the head receiving portion 3. In other words, the cushion unit 9 can be partially removed from the protective helmet 1.

In order to allow the helmet wearer 5 a view of the protective helmet 1 that is as unhindered as possible, a sighting area 12 is provided which, with the protective helmet 1 attached, is arranged at least substantially at the level of a center face of the helmet wearer 5. Furthermore, in the region of a chin 13 (see FIG. 6) of the helmet wearer 5, a chin protection region 14 is provided, which protects the chin 13 against injury in the event of an impact.

In order to ensure that the padding unit 9 does not fall out of the head receiving area 3 of the protective helmet 1, it can be held securely in position in the head receiving area 3. In this case, at least one first fastening element 15 and at least one second fastening element 16 are provided in the protective helmet 1, which correspond with each other, so that the two fastening elements 15, 16 are connectable to each other. To connect the two fastening elements 15, 16 with each other, they are to be aligned with each other or to each other, that the first and the second

Fastener 15, 16 along a common plug connection direction 17 can be moved relative to each other until the two fasteners 15,

16 engage each other, whereby a plug connection is realized. If the padding unit 9 is inserted into the head receiving area 3, but not yet connected to the protection unit 8 by means of the fastening elements 15, 16, a free volume of the head receiving area 3 in this state is lower compared to a free volume when the plug connection is realized.

There is further provided a removal unit 18, via which the first

Fastener 15 and the second fastener 16 are detachable from each other. In particular, if the helmet wearer can no longer decide freely whether the protective helmet 1 is to be removed from the head 4, for example because the helmet wearer 5 is an accidental, unconscious motorcyclist, it is advantageous that the first and the second fastening element 15 , 16 and consequently the protective unit 8 and the padding unit 9 are detachable from each other by means of the removal unit 18 along a direction of release 19 oriented transversely to the plug-in direction 17. It is particularly preferred that the release direction 19 and a longitudinal axis 20 of the helmet support 5 and the head 4 of the helmet support 5 to each other at a particularly low angle. In particular, the release direction 19 may be arranged at least substantially parallel to the longitudinal axis 20. In this way, it is possible for an outsider, for example a first responder, rescue personnel, etc., in a particularly simple manner, the padding unit 9 or at least one padding element 11 or a plurality of padding elements 11 at least substantially along the longitudinal axis 20 from the head receiving area 3 to remove the protective helmet 1. If the padding unit 9 is at least partially removed from the head receiving region 3 of the protective helmet 1, it is then possible in a particularly simple manner to detach a remainder of the protective helmet 1, cranially, from the head 4 along the longitudinal axis 20, that is to say above. In this way, it is ensured that the protective helmet 1 can be removed particularly gently from the head 4 of the helmet wearer 5 without further injuring the helmet wearer 5 or further aggravating any possible injury to the helmet wearer 5.

FIG. 2 furthermore shows that the protective helmet 1 can have a multiplicity of first fastening elements 15 and a multiplicity of second fastening elements 16, wherein a first fastening element 15 in each case corresponds to a second fastening element 15

Fastener 16 is assigned or vice versa and the associated fasteners 15, 16 each with each other form a connector pair. Furthermore, it is schematically illustrated in FIG. 2 that the removal unit 18 can have at least one pulling element 21, via which the first responder or the rescuer particularly easily grips the upholstery unit 9 or the upholstery elements 1 1 to be removed from the head receiving area 3 of the protective helmet 1 can. For example, the tension element may be formed as a loop, which may be connected directly to the cushion unit 9 or directly to the cushion elements 11 to be removed from the head receiving area 3 in a force, shape and / or material fit, for example sewn. It is to be understood that the pulling element 21 or the loop or loops can be integrated in an aesthetically pleasing manner into a design or a shape of the protective helmet 1.

In each case in a side view, Fig. 3 shows a protective element 10 and Fig. 4 is a cushion member 1 1. In the present example, the first fastening element 15 on a push-button receptacle 22, while the second fastening element 16 a

Push button 23 has. In particular, the first fastening element 15 may be formed as the push button receptacle 22, while the second fastening element 16 may be formed as the push button 23. To the connector by means of the first To realize fastener 15 and the second fastener 16, the push button 23 is pressed into the push-button receptacle 22 so that the

Fasteners 15, 16 are held fixed to each other position. Since the first fastening element 15 is fixedly connected to the protective element 10 and the second fastening element 16 is firmly connected to the padding element 1 1, that is

Upholstered element 1 1 and the protective element 10 as a result held mutually fixed position as soon as the connector is realized. The protective element 10 and the upholstery element 1 1 can be arranged in a particularly positionally secure manner to one another by, as already described, in each case a multiplicity of first fastening element 15 of the second fastening element 16 being used.

In order to avoid when removing the pad member 11, that this moves in the medial direction, that is towards an imaginary center of the head 4, it is provided that the pad member 1 1 at a removal via the removal unit 18 via a slot 24th the removal unit 18 from the

Push button receptacle 22 can disengage. This ensures that when using the removal unit 18 when removing the padding element 1 1 only very little, ideally no pressure is exerted on the head 4.

To ensure in the same way that the second fastener 16 and the push button 23, after it is disengaged via the slot 24 from the push-button receptacle 22, is particularly resistant at least substantially along the longitudinal axis 20 of the head receiving portion 3 can be removed, the

Removal unit 18 to the release direction 19 parallel depressions 25 which are formed in the protection unit 8. A respective recess 25 opens via the slot 24 in a respective push-button receptacle 22. Here, the respective recess 25 penetrate a particularly resistant plastic portion of the protection unit 8 and the protective element 10 to ensure that the push button 23 is particularly simple and non-destructive from the push-button receptacle 22 and

As a result, from the pressure button receptacle 22 surrounding, resistant plastic portion of the protection unit 8 can slide out.

It may additionally be provided that the respective recess 25 opens into a lower edge 26 of the protective element 10 with an end remote from the push-button receptacle 22. Therefore, after a disengagement of the push button 23 from the

Push button receptacle 22 in the release direction 19 of the push button 23 through the slot 24 out of the push-button receptacle 22 and enter into the respective recess 25. at a further sliding of the pad member 11 on the protective element 10 engages accordingly the push button 23 in the respective recess 25, and slides within the recess 25 escape the edge 26 until the push button 23 the

Leaves protective element 10 completely. Thus, it is ensured that upon removal of the pad member 11 from the head receiving portion 3 neither upon release of the connector nor during a movement of the pad member 1 1 from the

Head receiving portion 3 out medial moving the pad member 11 takes place. As a result, the head 4 of the helmet wearer 5 during an entire release and

Removal process of the cushion member 11 is not subjected to a particularly high pressure.

Fig. 5 shows in a plan view a first fastening element 15, wherein the

Push button receptacle 22 and the slot 24 are particularly easy to recognize. In order to be able to anchor the first fastening element 15 in a particularly stable position to the protective element 10 or to the protective unit 8, the first fastening element 15 or the push-button receptacle 22 can be surrounded by an annular disk element 27, via which the first fastening element 15 or the push-button receptacle 22 a protective element main body 28 (see Fig. 3) is supported. Furthermore, it can be seen in FIG. 5 that the annular disk element 27 has an opening which is arranged congruently to and / or on a recess 25, so that the pushbutton 23 arranged in the push-button receptacle 22 protrudes out of the push-button receptacle 22 and thus into the recess Indent recess 25 can. In other words, a respective recess 25 communicates via a respective slot 24 with a respective one

Push-button receptacle 22.

FIG. 6 shows a sectional view of the first fastening element 15, which has a fastening portion 29 and a retaining element 30. In the present example, the fastening portion 29 extends from the annular disk element 27 of the first fastening element 15 through the protective element 10 or the

Protective element base body 28 completely through and is held on a head 4 of the helmet wearer 5 side facing away from the protective element 10 by means of the holding member 30. For this purpose, the attachment portion 29 may have a tooth structure, which corresponds to a clip structure of the holding member 30, wherein the clip structure and / or the tooth structure are each formed so that a respective movement of the annular disc member 27 and the holding member 30 away from the protective element 10 is blocked. The protective element main body 28 and the holding element 30 may be integrally formed with each other, so that at least part of the protective unit 8, for example, the. By the protective element base body 28 and the holding member 30 Protective element 10 is formed. In any case, the protective element base body 28 is arranged between the annular disk element 27 and the retaining element 30, while the annular disk element 27 and the retaining element 30 each directly or directly adjoin the protective element base body 28.

Fig. 7 shows a perspective view of the applied to the head 4 of the helmet wearer 5 protective helmet 1 facing the chin 13 of the helmet wearer 5. On the basis of this illustration is particularly easy to see how by means of an outside person, such as the first responder, the protective helmet 1 is very gently remove from the head 4 of the helmet carrier 5. Beforehand, the first fastening element 15 and the corresponding second fastening element 16 in FIG

Plug connection direction 17 releasably connected to each other, after which the helmet carrier 5 the protective helmet 1 applies, whereby the head 4 and at least partially a neck 31 of the helmet support 5 are surrounded by the protective helmet 1.

If the helmet wearer 5 suffers an accident and thereby loses his consciousness, then there is an emergency in which the first responder or rescue personnel removes the protective helmet 1 from the head 4 of the helmet carrier 5 in order to provide vital functions of the helmet wearer 5

control and in particular restore. In order to remove the helmet 1 in a cranial direction from the head 4, without a tensile force and / or

Exert pressure on the head 4, become the first and the second

Fastener 15, 16 along the transverse direction of the connector 17 oriented release direction 19 detached from each other. As a result, the protection unit 8 and the cushion unit 9, in each case at least partially, are detached from one another in the release direction 19 by means of the removal unit 18. In other words, it is possible for the first responder to remove the upholstery element 1 1 to be removed from the head receiving region 3 or the upholstery elements 1 1 to be removed from the head receiving region 3 by means of a respective tension element 21 in a particularly simple manner parallel to a longitudinal axis 20 of FIG

Helmet carrier 5, that is, caudal to remove from the rest of the protective helmet 1. In this case, in particular, a medial movement of the padding elements 11 to be removed or of the padding element 11 to be removed remains so that no further pressure is exerted on the head or skull 4 of the helmet wearer 5. Since the padding elements 11 to be removed from the head receiving region 3 support a particularly tight fit of the protective helmet 1 on the head 4, the remainder of the protective helmet 1 can be removed from the head 4 in a particularly simple manner after removal of the corresponding padding elements 11. In summary, the invention shows how a particularly simple and gentle Helmentnahme can be realized after an accident.
