Technical Field

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

Background

In most countries, motorcycle drivers are forced to wear protective helmets because they face a particularly high risk compared to drivers of passenger cars. The risk of suffering particularly serious head injuries, especially in traffic accidents, is particularly high. In the following, a helmet wearer is understood to be a person who regularly wears a protective helmet on his head. The anatomical location specification relates to a healthy person. In order to be able to perform its protective function particularly effectively, the protective helmet rests directly on the head of the helmet wearer or motorcycle driver. However, this entails the problem that it is only very difficult for emergency personnel to remove the protective helmet from the helmet wearer in the event of an accident. Solutions are known for particularly simple removal of a protective helmet from an accident helmet wearer.

EP 1854368 a2 discloses a protective helmet, in particular for motorcyclists, comprising a helmet shell forming a head-receiving region, the helmet shell having an opening towards the shoulder region of the helmet wearer. The protective helmet furthermore comprises a protective unit arranged in the head receiving region, which protective unit directly adjoins the helmet shell and on which at least one first fastening element is arranged. Furthermore, a cushion unit is provided which is arranged in the head receiving region and which rests directly on the head of the helmet wearer and on which at least one second fastening element is provided, which can be detachably connected to the corresponding first fastening element in the plug-in direction. Furthermore, the protective helmet has a removal unit by means of which the first and second fixing elements can be separated from one another.

When removing the padding unit from such a conventional protective helmet, during which the protective helmet is positioned on the head of the helmet wearer, pressure is exerted on the head of the helmet wearer at least for a short time, since the first and second fixing elements should be separated from one another counter to the plugging direction. In general, the insertion direction of the two fastening elements is oriented at least substantially perpendicularly or at least substantially radially to the head of the helmet wearer. There is therefore a need for a protective helmet that can be removed particularly simply or gently from the helmet wearer in the event, in particular so as not to aggravate the possible injuries, such as head injuries and/or spinal injuries, that result from the removal of the protective helmet.

Disclosure of Invention

The object of the invention is to improve a conventional protective helmet in such a way that it can be removed particularly gently from the head of the helmet wearer. According to the invention, this object is achieved by a protective helmet having the features of patent claim 1. Furthermore, a method for using such a protective helmet should be provided, by means of which the protective helmet can be removed particularly gently from the head of the helmet wearer. According to the invention, this object is achieved by a method for using a protective helmet having the features of patent claim 9.

Advantageous embodiments of the invention are the subject matter of the dependent claims and the description. The advantages and advantageous embodiments of the protective helmet according to the invention are to be considered as advantages and advantageous embodiments of the method of using a protective helmet according to the invention and vice versa.

In order to further develop a conventional protective helmet such that it can be removed particularly gently from the head of the helmet wearer, it is provided according to the invention that the first and second fastening elements, and thus the protective unit and the cushion unit, can be separated from one another at least in part by means of the removal unit in a separation direction oriented transversely to the plugging direction. This means that at least substantially, ideally no movement of the cushion unit to the middle, i.e. to the imaginary head or skull centre point, takes place at all. A plurality of pairs of fixing elements having first and second fixing elements, respectively, may be provided on the protective helmet so as to detachably connect the pad unit and the protective unit to each other. The cushion unit and the protective unit are thus arranged in a particularly positionally stable manner relative to one another, so that it is ensured that the helmet shell does not undergo undesired movements on the head of the helmet wearer and can be fixed as desired.

Thus, when an accident occurs, particularly when it is unconscious, by a helmet wearer or motorcycle driver, the emergency personnel can therefore remove or remove the protective helmet from the helmet wearer's head without further exacerbating the danger of exposing the motorcycle driver or helmet wearer to possible head injury.

If the pad unit is at least partially separated from the protective unit by means of the removal unit, such as only one pad element or a plurality of pad elements of the pad unit, and removed from the head receiving region of the protective helmet, the helmet shell together with the protective unit remaining therein and possibly the remaining pad units can be removed particularly gently or simply from the head of the accident helmet wearer. It is considered particularly gentle and safe to remove the helmet in the cranial direction from the head of the helmet wearer, which is based on the fact that the previous removal of the padding unit or at least one of the padding elements takes place with only little effort.

It has proven to be advantageous if one of the fastening elements has a push button and the other fastening element has a push button receptacle with a portion of the removal unit which is designed as a slot which laterally opens the push button receptacle. This means that if the second fastening element is configured as a push button receptacle, the first fastening element can be configured as a push button. Accordingly, if the second fixing element is configured as a push button, the first fixing element can be configured as a push button receptacle. In any case, the button accommodation portion has a slot configured to release the button from the button accommodation portion when the cushion unit and the protection unit slide away from each other in the separation direction. If two fixing elements corresponding to one another form such a button-button receptacle connection and the slot is part of a removal unit, a protective helmet which can be removed particularly gently from the head of an injured helmet wearer can be produced particularly simply or effortlessly. Furthermore, the removal unit avoids incorrect operation, wear and/or damage on account of its particularly simple construction, in particular without moving parts.

Furthermore, it has proven to be advantageous if the separation direction extends at least substantially parallel to the longitudinal axis of the head of the helmet wearer. The longitudinal axis of the body of a person, such as a helmet wearer, is the section line, which is formed by the coronal plane of the body and the sagittal plane of the body, which intersects it perpendicularly. In particular, the separation direction is oriented from the head of the helmet wearer via the torso toward the feet of the helmet wearer, i.e. in the direction of the feet. In other words, it is provided that the cushion unit is removed from the helmet wearer's head downwards, whereas the protective helmet is removed from the head upwards, i.e. in the direction of the skull bone. In this way, it is ensured that when the protective helmet is removed from an injured and/or unconscious helmet wearer, the protective helmet is not damaged or the damage that may be present is further aggravated by the removal thereof. Since the spine of the helmet wearer can be at least substantially stretched and/or held in its current position when the protective helmet is removed in the direction of the cranium.

In order to enable the emergency personnel to remove the pad unit from the protective helmet of the helmet wearer in the event of an accident in a particularly simple manner, the removal unit can have a pulling element by means of which the pad unit can be pulled out of the head receiving region in the separating direction, i.e. towards the foot. The emergency personnel can thus pull the pad unit out of the head receiving region of the protective helmet in a separating direction by means of the pulling element in a particularly simple manner. A particularly easy-to-grasp handle is provided for emergency personnel or personnel pulling the padding unit out of the protective helmet or its head receiving area by means of the pulling element for operating the padding unit or the one or more padding elements to be removed from the head receiving area.

Furthermore, it can be provided that the removal unit has at least one recess in the protective unit, which recess extends parallel to the separating direction. In particular, the dimensions of these recesses correspond at least substantially to the dimensions, such as the diameter, of the push button, so that the push button can slide in the recesses when the cushion unit is pulled out of the head receiving area. It is desirable to provide a recess in the protective unit for each first fixing element or each second fixing element. In particular, the corresponding recess can open into the button receiver via the slot, so that the button, when it emerges from the button receiver, enters the corresponding recess via the slot. The recess may be provided on a particularly stable and/or deformation-resistant, e.g. tear-off or the like, part or section of the protection unit. This means that the recess allows emergency personnel to be able to separate the cushion unit from the protective unit particularly simply without having to apply a force to break or tear a particularly robust section. The end of the recess facing away from the button accommodation can open into the lower edge of the protective unit, which at the same time can form the lower edge of the protective helmet, so that the button sliding in the recess can slide out of the protective unit without hindrance. In other words, the recess may extend through the polystyrene portion of the protection unit, thereby further simplifying removal of the pad unit for emergency personnel.

In the case of the at least one button accommodation provided on the cushion unit, at least one such recess can be provided on the cushion unit in a similar manner, but with its end turned 180 degrees away from the button accommodation, i.e. opening into the upper edge of the cushion unit or cushion element. By means of the at least one recess, it is ensured that the cushion unit or the cushion element and the protective unit can be slid off from one another particularly simply when the cushion unit or the cushion element is pulled out, wherein the first or second fastening element is not obstructed by the particularly hard protective unit.

Furthermore, the first fixing element can have an elongated fixing portion which passes completely through the protective unit and a retaining element which retains the fixing portion on the side of the protective helmet facing away from the head of the helmet wearer. The first fastening element can thereby be connected to the protective element base of the protective unit in a particularly simple and easy manner. For example, it can be provided that the elongated fastening portion has a tooth structure which at least substantially corresponds to the clamping structure of the holding element. For example, the fastening portion can be fastened to the button receptacle of the first fastening element or connected thereto, so that the fastening portion extends through the protective element and out. When the first fixing element is mounted, the fixing portion extends correspondingly through the retaining element arranged on the side facing away from the head of the helmet wearer, so that a movement of the fixing portion in the direction of the head of the helmet wearer is prevented by the interaction between the tooth structure and the clamping structure. In other words, the protective element base is respectively arranged directly between the holding element and the button receptacle.

It is particularly advantageous if the padding unit comprises at least one padding element for the left and right cheek of the helmet wearer, respectively. In other words, the padding unit can have a plurality of padding elements, one of which rests on the left cheek of the helmet wearer and the other rests on the right cheek of the helmet wearer. In addition, further padding elements of the padding unit can be provided, which rest against further regions of the head of the helmet wearer in order to achieve a particularly comfortable wearing sensation for the helmet wearer when wearing the protective helmet. In particular, the cushion element for the left cheek and the cushion element for the right cheek can be connected to one another, for example, by means of an arched cam element, so that the cushion element can be positioned particularly easily in the head receiving region.

The protective helmet may be configured as a reversible helmet. This means that the helmet shell may comprise a front shell element and a rear shell element pivotably connected thereto. Such a reversible helmet is considered particularly comfortable because, for example, the chin guard can be flipped up to release the helmet wearer's face without having to completely remove the reversible helmet from the head. In order not to impede the turning function of the protective helmet, the protective unit and the padding unit may each be segmented, i.e. have a plurality of protective or padding elements, respectively.

The invention also relates to a method of use of a protective helmet, in particular for motorcyclists, comprising a helmet shell forming a head-receiving zone, the helmet shell having an opening facing the shoulder area of the helmet wearer; a protective unit arranged in the head receiving area, directly adjoining the helmet shell and provided with at least one first fastening element; and a pad unit arranged in the head receiving area, which directly rests on the 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 fixing element are detachably connected to one another in the plugging direction and are separated from one another in an emergency by a removal unit. In order to remove the protective helmet particularly gently from the head of the helmet wearer, it is provided in the method according to the invention that the first and second fastening elements, and thus the protective unit and the cushion unit, are separated from one another by means of the removal unit in a separation direction oriented transversely to the plugging direction.

The elements and/or features described in connection with the method correspond in form and function to the elements and/or features described in connection with the protective helmet, and a renewed description of these elements/features is therefore omitted here.

An emergency situation in connection with the method or in connection with a protective helmet is understood to be a situation in which the helmet wearer cannot consciously decide whether the protective helmet should be removed from his head. This is particularly the case if the helmet wearer is an accident motorcycle driver who is unconscious after a traffic accident. Emergency personnel providing first aid to an accident motorcyclist are now faced with the task of removing the protective helmet from the motorcyclist's head in order to be able to take further measures within the scope of the first aid. To this end, the protection unit and the pad unit are at least partially separated from each other by separating them from each other in a separation direction extending parallel to the longitudinal axis of the motorcycle driver and towards the shoulder area of the motorcycle driver. In other words, the emergency personnel can pull the pad unit or a component of the pad unit, such as one or more pad elements, downward from the head receiving area of the protective helmet so that the remaining protective helmet defined by the helmet shell can then be removed upward, i.e. in the cranial direction, from the head of the motorcyclist who has suffered the accident. In this way, it is particularly advantageously ensured that emergency personnel do not have to excessively move the head of the motorcycle driver in order to remove the protective helmet from the head of the motorcycle driver, so that the risk of injury to the motorcycle driver as a result is particularly low.

The protective helmet according to the invention and the method according to the invention reduce the anxiety of emergency personnel in helping accident victims. As the emergency personnel do not have to worry about harming the motorcyclist or further aggravating the possible injuries when removing the protective helmet. The protective helmet and the method proposed herein are therefore particularly suitable for further improving emergency measures in road traffic, whereby the consequences of an accident can be reduced.

Further features of the invention emerge from the claims, the figures and the description of the figures. The features and feature combinations mentioned in the above description and the features and feature combinations mentioned in the following description of the drawings and/or shown in the drawings individually can be used not only in the respectively given combination but also in other combinations or alone.

Drawings

The invention will now be explained in detail by means of preferred embodiments and with reference to the accompanying drawings. The attached drawings are as follows:

FIG. 1 shows a schematic view of a protective helmet taken along the sagittal plane;

FIG. 2 shows a schematic view of a protective helmet taken along the coronal plane;

Detailed Description

Fig. 1 and 2 each show a protective helmet 1 in a schematic representation in a section plane, wherein the section plane in fig. 1 is the human sagittal plane and the section plane in fig. 2 is the coronal plane. 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 configured to accommodate or at least substantially completely cover a head 4 (see fig. 6) of a helmet wearer 5 (shown only in fig. 6 for clarity). For this purpose, the protective helmet 1 has an opening 7 facing the shoulder region 6 (see fig. 6), through which the protective helmet 1 can be slipped onto or worn on the head 4 of a helmet wearer 5.

In order to be able to exert their intended protective effect particularly effectively in the protective helmet 1, the head receiving region 3 is at least substantially completely covered by the protective unit 8. Such protection units are already well known in the art and are only described here roughly. The protective unit 8 is usually made of plastic and is designed to absorb forces acting on the protective helmet 1 from the outside in the event of an impact on the protective helmet 1, in particular in the event of a traffic accident, in which the protective unit 8 absorbs forces under its own defined deformation. Thereby ensuring that head injury to the helmet wearer 5 is not serious or ideally completely avoided.

Furthermore, it is also required that the protective helmet 1 is particularly close to the head 4 of the helmet wearer 5. In order to achieve the best possible wearing comfort, a cushion unit 9 is also provided in the head receiving region 3, which cushion unit rests directly on the head 4 of the helmet wearer 5 when the protective helmet 1 is worn. This means that the protective unit 8 is arranged between the helmet shell 2 and the cushion unit 9. In particular, the protective unit 8 can be fixed on the inside of the helmet shell 2 in a force-fitting, form-fitting and/or material-fitting manner inside the helmet shell 2, i.e. in the head receiving region 3.

In the case of a protective helmet 1 designed as a reversible helmet, its helmet shell comprises a front shell element and a rear shell element connected thereto, for example, by means of an articulation. Thus, the protection unit 8 can be divided or segmented, so that the protection unit 8 is composed of a plurality of protection elements 10 (see fig. 3). In a similar manner, the cushion unit 9 may be composed of a plurality of cushion elements 11 (see fig. 4). In particular, a right padding element 11 for the right cheek of the helmet wearer 5 and a left padding element 11 for the left cheek of the helmet wearer 5 can be provided. In addition, other padding elements 11, which are not described in detail here, can also be present in the protective helmet 1, for example adjacent to the back head of the helmet wearer 5. The separation of the cushion unit 9 into the individual cushion elements 11 can in particular extend in such a way that one cushion element 11 facing the opening 7 or a plurality of cushion elements 11 facing the opening 7 can be removed from the head receiving region 3 of the protective helmet 1, wherein further cushion elements 11, such as the cushion element 11 provided for the back head, can remain in the head receiving region 3. In other words, the cushion unit 9 can be partially removed from the protective helmet 1.

In order to be able to see the helmet wearer 5 out of the protective helmet 1 as unhindered as possible, a viewing area 12 is provided which is arranged at least substantially at the level of the middle face of the helmet wearer 5 when the protective helmet 1 is worn. Furthermore, a chin protection area 14 is provided in the area of the chin 13 (see fig. 6) of the helmet wearer 5, which chin protection area 14 protects the chin 13 from injury in the event of an impact.

In order to ensure that the cushion unit 9 does not fall out of the head receiving area 3 of the protective helmet 1, the cushion unit can be held in a stationary manner in the head receiving area 3. In the protective helmet 1, at least one first fastening element 15 and at least one second fastening element 16 are provided, which correspond to one another, so that the two fastening elements 15, 16 can be connected to one another. In order to connect the two fixing elements 15, 16 to one another, they are aligned with one another such that the first and second fixing elements 15, 16 can be moved toward one another in a common plugging direction 17 until the two fixing elements 15, 16 engage one another, so that plugging is effected. When the cushion unit 9 is inserted into the head receiving region 3, but is not yet connected to the protective unit 8 by means of the fastening elements 15, 16, the free volume of the head receiving region 3 is smaller in this state than when the plug-in connection is made.

Furthermore, a removal unit 18 is provided, by means of which the first fixing element 15 and the second fixing element 16 can be separated from one another. In particular, when the helmet wearer can no longer freely decide whether or not to remove the protective helmet 1 from the head 4, for example because the helmet wearer 5 is an unconscious motorcyclist in the event of an accident, it is advantageous if the first and second fixing elements 15, 16 and thus the protective unit 8 and the cushion unit 9 can be separated from one another by means of the removal unit 18 in a separation direction 19 oriented transversely to the plugging direction 17. It is particularly preferred that the separating direction 19 and the longitudinal axis 20 of the helmet wearer 5 or of the head 4 of the helmet wearer 5 extend at a particularly small angle to one another. In particular, the separation direction 19 can be arranged at least substantially parallel to the longitudinal axis 20. In this way, it is possible in a particularly simple manner for outside personnel, such as emergency personnel, rescue personnel or the like, to remove the pad unit 9 or the at least one pad element 11 or a plurality of pad elements 11 from the head receiving area 3 of the protective helmet 1 at least substantially along the longitudinal axis 20. If the pad unit 9 is at least partially removed from the head receiving area 3 of the protective helmet 1, the remainder of the protective helmet 1 can then be removed particularly simply along the longitudinal axis 20 towards the skull, i.e. upwards from the head 4. 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 injury to the helmet wearer 5 or further aggravating the possible injuries of the helmet wearer 5.

Fig. 2 also shows that the protective helmet 1 can have a plurality of first fastening elements 15 and a plurality of second fastening elements 16, each first fastening element 15 being assigned to a respective second fastening element 16 or vice versa, and the fastening elements 15, 16 assigned to one another each forming a plug-in pair. Furthermore, fig. 2 also shows schematically that the removal unit 18 can have at least one pulling element 21, by means of which an emergency or rescue person can grip the pad unit 9 or the pad element 11 to be removed from the head receiving area 3 of the protective helmet 1 particularly simply. For example, the pulling element can be designed as a pull ring which can be connected in a force-fitting, form-fitting and/or material-fitting manner, such as by sewing, directly to the cushion unit 9 or directly to the cushion element 11 to be removed from the head receiving region 3. It will be appreciated that the pulling element 21 or the one or more pull rings may be integrated into the design or form of the protective helmet 1 in an aesthetically attractive manner.

Fig. 3 shows one protective element 10 and fig. 4 shows one spacer element 11. In the present example, the first fixing element 15 has a button receptacle 22, while the second fixing element 16 has a button 23. In particular, the first fastening element 15 can be designed as a push button receptacle 22, while the second fastening element 16 can be designed as a push button 23. In order to achieve the plug-in connection by means of the first fixing element 15 and the second fixing element 16, the push button 23 is pressed into the push button receptacle 22, so that the fixing elements 15, 16 are held in a fixed position relative to one another. Since the first fastening element 15 is fixedly connected to the protective element 10 and the second fastening element 16 is fixedly connected to the spacer element 11, the spacer element 11 and the protective element 10 are held in a fixed position relative to one another once the plug-in connection has been made. As already described, the protective element 10 and the spacer element 11 can be arranged in a particularly positionally fixed abutment by using a plurality of first fixing elements 15 and a plurality of second fixing elements 16.

In order to prevent the spacer element from moving in the middle direction, i.e. in the direction of the imaginary center point of the head 4, when removing the spacer element 11, it is provided that the spacer element 11 can be pulled out of the button receiver 22 via the slot 24 of the removal unit 18 when removing it by means of the removal unit 18. This ensures that only a small pressure, ideally no pressure, is exerted on the head 4 when using the removal unit 18 when removing the spacer element 11.

In order to ensure in the same way that the second fixing element 16 or the push button 23 can be removed from the head receiving region 3 at least substantially along the longitudinal axis 20 with particularly little resistance after it has been pulled out of the push button accommodation 22 via the slot 24, the removal unit 18 can have a recess 25 which extends parallel to the separation direction 19 and is configured in the protective unit 8. The respective recess 25 opens into the respective button receiver 22 via the slot 24. The corresponding recess 25 can be inserted through the particularly solid plastic part of the protective unit 8 or of the protective element 10 in order to ensure that the pushbutton 23 can be slid out of the pushbutton receiver 22 and thus of the solid plastic part of the protective unit 8 surrounding the pushbutton receiver 22 in a particularly simple and non-destructive manner.

It can also be provided that the respective recess 25 opens into a lower edge 26 of the protective element 10 at the end facing away from the button receptacle 22. Thus, after the push button 23 is disengaged from the push button accommodation 22 in the disengagement direction 19, the push button 23 can be moved out of the push button accommodation 22 through the slot 24 and into the corresponding recess 25. When the spacer element 11 slides further down over the protective element 10, the push-button 23 correspondingly engages in the corresponding recess 25 and slides within the recess 25 towards the edge 26 until the push-button 23 is completely clear of the protective element 10. This ensures that the spacer element 11 cannot move medially when the spacer element 11 is removed from the head receiving region 3, either during a undocking or when the spacer element 11 is removed from the head receiving region 3. Thus, the head 4 of the helmet wearer 5 is not subjected to particularly high pressures throughout the separation and removal of the padding elements 11.

Fig. 5 shows the first fastening element 15 in a plan view, where the button receivers 22 and the slots 24 can be seen particularly clearly. In order to be able to anchor the first fastening element 15 particularly positionally stably to the protective element 10 or the protective unit 8, the first fastening element 15 or the button receiver 22 can be surrounded by a washer element 27, by means of which the first fastening element 15 or the button receiver 22 is supported on a protective element base 28 (see fig. 3). Furthermore, it can be seen in fig. 5 that the washer element 27 has an opening which coincides with the recess 25 and/or is arranged on the recess such that the push button 23 arranged in the push button accommodation 22 can be moved out of the push button accommodation 22 and thus into the recess 25. In other words, the respective recesses 25 communicate with the respective button accommodation portions 22 via the respective slots 24.

Fig. 6 shows the first fixing element 15 in a sectional view, with a fixing portion 29 and a retaining element 30. In the present example, the fastening portion 29 extends from the washer element 27 of the first fastening element 15 completely through the protective element 10 or the protective element base 28 and is held by means of the holding element 30 on the side of the protective element 10 facing away from the head 4 of the helmet wearer 5. For this purpose, the fastening portion 29 can have a toothing corresponding to the clamping structure of the retaining element 30, the clamping structure and/or the toothing each being configured such that a movement of the washer element 27 and the retaining element 30 away from the protective element 10 is prevented. The protective element base 28 and the holding element 30 can be designed in one piece with one another, so that at least one part of the protective unit 8, for example the protective element 10, is formed by the protective element base 28 and the holding element 30. In any case, the protective element base 28 is arranged between the washer element 27 and the retaining element 30, while the washer element 27 and the retaining element 30 respectively directly adjoin the protective element base 28.

Fig. 7 shows the protective helmet 1 placed on the head 4 of a helmet wearer 5 in a perspective view looking at the chin 13 of the helmet wearer 5. From this figure it is particularly clear how an outside person, such as an emergency person, can particularly gently remove the protective helmet 1 from the head 4 of a helmet wearer 5. Before this, the first fastening element 15 and the corresponding second fastening element 16 are detachably connected to one another in the plug-in direction 17, after which the protective helmet 1 is worn by the helmet wearer 5, so that the head 4 and at least part of the neck 31 of the helmet wearer 5 are enclosed by the protective helmet 1.

If the helmet wearer 5 suffers an accident and thus loses his consciousness, there is an emergency situation in which emergency personnel or rescue personnel remove the protective helmet 1 from the head 4 of the helmet wearer 5 in order to control and in particular restore the vital functions of the helmet wearer 5. In order to be able to remove the protective helmet 1 from the head 4 in the cranial direction without applying a tensile and/or compressive force to the head 4, the first and second fixing elements 15, 16 are separated from one another in a separation direction 19 oriented transversely to the plugging direction 17. Thus, the protective unit 8 and the pad unit 9 are each at least partially separated from one another in a separation direction 19 by means of the removal unit 18. In other words, the first-aid person can remove the one or more padding elements 11 to be removed from the head receiving area 3 from the rest of the protective helmet 1 by means of the respective pulling element 21 particularly simply parallel to the longitudinal axis 20 of the helmet wearer 5, i.e. in the direction of the foot. The one or more padding elements 11 to be removed are in particular not moved towards the middle, 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 assist the protective helmet 1 to fit particularly firmly on the head 4, the remainder of the protective helmet 1 can be removed particularly simply from the head 4 after removal of the respective padding elements 11.

In summary, the invention shows how a particularly simple and gentle removal of the helmet after an accident can be achieved. In order to ensure a secure fit of the protective helmet 1, the cheek pads or at least some of the padding elements 11 rest particularly tightly against the head 4 of the helmet wearer 5, so that these padding elements 11 in the cheek region hinder a simple removal of the protective helmet 1. By means of the removal unit, the emergency personnel can remove the cheek pads or padding elements 11 from the protective helmet 1 from the outside by pulling, in particular via the pulling elements 21, so that the protective helmet 1 can then be removed particularly simply from the head 4 of the victim or helmet wearer 5.

It is important to note that the spacer element 11 to be removed does not move in a directional manner toward the middle, i.e., toward the imaginary center point of the head 4, since the helmet can thus be removed from the potentially injured and/or comatose helmet wearer 5 without applying pressure to the head 4.
