Description

The present patent application takes priority over the German patent application DE 10 2019 216 846.9 claim, the contents of which are incorporated herein by reference.

The invention relates to a head protection interior for a head protection, such as a helmet, a cap, a hood, a shield, a visor or the like. The head protection is able to at least partially protect the head of the wearer. For example, it is able to exclusively or additionally protect the face and / or ears of the wearer. In particular, the head protection is designed as work head protection and forms, for example, personal protective equipment for the wearer. Furthermore, the invention is directed to a head protection arrangement with such a head protection interior.

From the prior art, different head protection interior fittings are known through public prior use, which are locally fixed, for example, on a respective helmet shell. The head protection interior fittings are generally adjustable in size so that the same helmet shells can be used and a head protection arrangement that is as precisely fitting as possible can be offered. The disadvantage is that the wearing comfort and fit of the head protection arrangement are often unsatisfactory.

The US 2017/0245578 A1 discloses a suspension for a head protection and a corresponding head protection, such as a safety helmet. The suspension can be attached to a helmet shell via at least one hanger and comprises a horizontal band which is designed to encircle the head of a head protection wearer. It also has at least one curved one Section extending from the horizontal band and configured to pass over the head of the head protection wearer. A back of the head support portion of the suspension is configured to rest against the back of the head of the head protection wearer. The back of the head support section has an adjustment wheel. It is coupled to the horizontal belt via a coupling section which runs obliquely downward from the horizontal belt. This known suspension is often not particularly well adaptable to certain head shapes.

From the DE 698 11 738 T2 a protective helmet with a suspension arrangement is known. The suspension assembly has a crown support assembly / cap and an adjustable headband at the top, as well as a plurality of connectors for releasably attaching the suspension assembly to a helmet shell.

One in the WO 2009/048794 A1 The disclosed head suspension comprises a headband for wrapping around a head of a wearer and at least one top strap which passes over the head of the wearer and is in communication with the headband. Two transition arms run obliquely downward from the headband and carry a rear support section which can have an adjustment element. The head suspension also includes a fastener to couple a head protection element to the head suspension.

The invention is based on the object of eliminating the problems of the prior art. In particular, head protection interior equipment is to be provided which can be individually adjusted to a wide variety of head shapes and / or head sizes in order to achieve an extremely high level To deliver comfort and very safe head protection. A corresponding head protection arrangement is also to be created.

According to the invention, this object is achieved by the features specified in the main claims 1 and 13. The essence of the invention lies in the at least one first securing device and the at least one neck coupling section, which are formed separately from one another. They are separated or decoupled from one another. The at least one upper head coupling section is preferably in, preferably more direct and / or fixed, connection with the at least one first fixing device. The expression "the at least one first securing device is formed separately from the at least one neck coupling section" is preferably understood here to mean that they are nonetheless connected to one another, for example indirectly, in particular via the (respective) at least one upper head coupling section and the base section can stand.

The at least one neck coupling section is thus unaffected by the at least one first securing device due to its separate or separate configuration. A displacement of the at least one neck coupling section relative to the at least one first securing device or the at least one top head coupling section, which occurs, for example, when the head protection interior is adjusted in size / circumference, is possible. A degree of freedom in the adjustability of a strap / headband of the head protection interior for adapting the head protection interior is consequently particularly high. The fastener tape is therefore virtually able to contract or expand along its longitudinal direction without significant impairment due to a local fixation on the head protection. A circumference adjustment is like this in comparison with known head protection interior fittings clearly improved. The head protection interior can be easily and precisely adapted to the wearer's head. The head protection sits securely on the wearer's head and can thus reliably develop its full protective effect.

The, in particular completely, separate design of the at least one neck coupling section and each at least regionally adjacent upper head coupling section enables a relative movement, in particular relative displacement, between them, which happens, for example, when the head protection interior is adjusted in size. The expression "the at least one neck coupling section and each at least regionally adjacent upper head coupling section are formed separately" is preferably understood here to mean that they can nevertheless be connected to one another, for example indirectly, in particular via the base section.

The head protection interior is slotted or divided in the area of the at least one neck coupling section and each at least regionally adjacent top head coupling section. It is expedient if at least one, in particular slot-like, recess / opening is arranged in the base section adjacent to the respective separating slot. The at least one recess / opening and the adjacent separating slot are preferably located at the same height.

When the head protection arrangement is worn, the coupling sections preferably run at least in some areas at different heights. For example, they extend at least in some areas at a distance to each other. At least regional overlaps between these are possible.

Ideally, the head protection interior can be adapted to all common head sizes and shapes. This eliminates the otherwise common need to keep several size models of the head protection interior equipment available in order to be able to cover all common head sizes and shapes.

The at least one neck coupling section is preferably formed from a plastic material. The at least one overhead coupling section is preferably formed from a plastic material.

Each coupling section is favorably connected directly and / or firmly to the base section.

It is expedient if the base section is designed in the form of a band or a plate. It is formed from a plastic material, for example. The base section favorably has a certain dimensional stability, but is preferably nonetheless deformable.

The at least one neck coupling section of the head protection interior is preferably elongated and thus has a longitudinal direction. It is advantageous if it is band-shaped or web-shaped, in particular over its entire length. The length of the at least one neck coupling section is determined in particular by its extension between the base section and the neck arrangement. In particular, the at least one upper head coupling section is elongated and thus has a longitudinal direction. Conveniently, he is, especially over his whole Length, band-shaped or web-shaped. The length of the at least one top-head coupling section is preferably determined by its extension between the base section and the top-head arrangement. Preferably the base portion is elongated and has a longitudinal direction. The longitudinal direction of the base section and the top-head coupling section essentially corresponds to the circumferential direction of the head of the wearer when the head protection interior is worn.

The neck arrangement advantageously comprises a first adjusting piece and a second adjusting piece, which can be adjusted relative to one another in order to change the length of the neck contact. It is expedient if the adjustment pieces can be locked in different size positions relative to one another, for example in a latching manner. Known adjusting / locking devices are preferably used to adjust the length and lock the neck arrangement. An effective length of the neck arrangement and, in particular, an effective extent of the interior head protection equipment can be adjusted in this way. In use, the neck arrangement preferably rests against the neck or in a lower region of the back of the head of the wearer. It is, for example, connected in one piece to the at least one neck coupling section or originally separate from it.

The overhead arrangement is designed, for example, as a basket, bracket, bow or the like. It preferably comprises at least one overhead band or an overhead bar. It is useful if the top head arrangement is formed from a plastic material. In use, it preferably rests against the upper head of the wearer and is, for example, connected in one piece to the at least one upper head coupling section or originally separate from it. It is able, for example, to lie laterally on the head of the wearer.

The at least one first securing device is preferably designed as an integral, frictional and / or positive locking securing device. She is able to locate the head protection interior on the head protection. The at least one first securing device is thus also able to locate the upper head arrangement in relation to the head protection. The at least one first securing device is advantageously able to locate the at least one upper head coupling section on the head protection. The at least one first fixing device comprises, for example, at least one anchor element for local fixing on the head protection. It includes, for example, a latching element, plug-in element, a rivet or the like. For example, the at least one first securing device is pin-like, tab-like or the like. It is advantageous if the at least one first securing device is arranged in a lateral, in particular laterally rear, area of the head protection interior or, in the assembled state, in a lateral, in particular laterally rear, area of the head protection arrangement.

Further advantageous refinements of the invention are specified in the subclaims.

The embodiment according to dependent claim 2 results in a head protection interior which is adjustable to a particularly large extent. It is preferred if the at least one neck coupling section is at least 10%, preferably at least 15%, preferably at least 20%, preferably at least 25%, longer than each at least regionally adjacent top head coupling section. In particular, this difference in length is at most 100% (the at least one neck coupling section has in particular at most twice the length of each at least regionally adjacent upper head coupling section), preferably at most 75%, particularly preferably at most 50%, particularly preferably at most 45%.

The overhead arrangement according to dependent claim 3 enables the head protection interior to be securely fixed in place on the head protection. This leads to a high level of wearing comfort and a secure fit. The upper head arrangement is preferably at least largely, in particular completely, stiff or essentially stiff.

The configuration according to dependent claim 4 leads to a secure connection between the upper head arrangement and the base section. The at least one overhead coupling section is preferably at least largely, in particular completely, flexible or essentially flexible.

The embodiment according to dependent claim 5 results in a head protection interior which can be individually adapted to the head of a wearer and can be changed over a particularly large extent. The at least one neck coupling section is preferably at least largely, in particular completely, flexible or essentially flexible.

The configuration according to dependent claim 7 again allows a particularly good and wide adjustment of the size of the head protection interior. The at least one neck coupling section extends, for example, in the mounted or worn state of the head protection interior further in the head protection circumferential direction from the at least a base section away than each top-head coupling section that runs at least partially adjacent. It extends in its longitudinal direction and / or the longitudinal direction from each at least regionally adjacent top head coupling section beyond each top head coupling section, in particular in the head circumferential direction.

The head protection interior according to dependent claim 8 has an overhead arrangement which is fixed locally in the assembled state of the head protection interior on the head protection, which leads to a particularly tight fit of the head protection on the head of the wearer.

The embodiment according to dependent claim 9 again results in a head protection interior which is particularly comfortable to wear and can be changed in size to an extremely large extent. The at least one neck coupling section remains unaffected or undisturbed by the at least one first securing device and / or the at least one upper head coupling section, in particular between the base section and the neck arrangement.

The head protection interior according to dependent claim 10 leads in particular to a neck arrangement which is displaced downwards relative to the base section, the at least one first fixing device and / or relative to the at least one top-head coupling section, which is safe when wearing the head protection interior Allows support of the head protection interior against the wearer.

The head protection interior according to dependent claim 11 again offers a particularly high level of wearing comfort. Furthermore, this is extremely good adjustable to the wearer's head. The storage facility enables flexible adaptation of the head protection interior to the respective wearer. A large number of setting options are preferred. It is useful if the bearing device is designed as a pivot bearing device. For example, the swivel bearing device allows the neck arrangement to be swiveled in latching steps.

The at least one second securing device according to dependent claim 12 is preferably arranged in a front area of the head protection interior or, in the assembled state of the head protection arrangement, in a front area of the head protection arrangement. It is designed, for example, as a material fit, force fit and / or form fit securing device. The at least one second fixing device comprises, for example, at least one anchor element for local fixing on the head protection. It includes, for example, a latching element, plug-in element, a rivet or the like. For example, the at least one second securing device is pin-like, tab-like or the like.

The head protection interior is preferably symmetrical or substantially symmetrical. Slight differences in the design of individual components are not taken into account here.

It is useful if the head protection interior has exactly one central base section. The head protection interior equipment advantageously has exactly two top-head coupling sections, which preferably run laterally away from the base section in opposite directions. The head protection interior also preferably comprises exactly two neck coupling sections, which preferably run laterally away from the base section in opposite directions. It is beneficial when in each case exactly one first fixing device is connected to an end region of the respective upper head coupling section facing away from the base section. Thus, there are preferably exactly two first fixing devices.

In particular, the base section, the neck coupling sections and / or the upper head coupling sections are each designed symmetrically or essentially symmetrically.

One in Fig. 1 , 2 The head protection arrangement shown in its entirety comprises a helmet shell 1 and interior fittings 2 fixed in place on the helmet shell 1. The head protection arrangement is essentially symmetrical with respect to a plane of symmetry E. It has a front area 3, a rear area 4 and two side areas 5 running between these. The plane of symmetry E extends from the front area 3 in the direction of the rear area 4.

The helmet shell 1 is designed as a hard shell, in particular a hard plastic shell. It delimits a head receiving space 6 and is not upholstered.

The interior trim 2 has a central elongated band-shaped base section 7 with two opposite end areas 8. Each end area 8 of the base section 7 is followed by an elongated band-shaped upper head coupling section 9 and an elongated band-shaped neck coupling section 10. Each upper head coupling section 9 adjoins the base section 7 in an upper area thereof, while each neck coupling section 10 adjoins the base section 7 in a lower area thereof. A separating slot 11 runs between each top-head coupling section 9 and the adjacent or underneath the neck coupling section 10, so that these adjacent coupling sections 9, 10 are designed separately or are separated from one another and are only connected to one another via the base section 7.

Each upper head coupling section 9 runs laterally away from the base section 7. It extends straight and / or curved slightly upwards. Each top-head coupling section 9 has a constant height HO which is between 40% and 60% of the height HB of the base section 7.

Each neck coupling section 10 runs laterally away from the base section 7 and has a constant height HN, which preferably corresponds to the height HO. The height HN is between 40% and 60% of the height HB of the base section 7.

Each neck coupling section 10 has a kink 12 which divides the respective neck coupling section 10 into a main section 13 adjoining the base section 7 and a spacer 14. Each spacer 14 forms an angle W with the adjacent main section 13 which, in the unloaded state of the interior trim 2, is between 120 ° and 160 °. Each main section 13 and the adjacent upper head coupling section 9 preferably run, at least in the unloaded state, at least partially parallel or essentially parallel to one another.

Each top-head coupling section 9 has a length LO. Each main section 13 has a length LH. The length LH of the main section 13 is smaller than the length LO of the top-head coupling section 9. It is between 60% and 95%, preferably between 70% and 90%, of the length LO of the top-head coupling section 9. Each spacer 14 has a length LB on that is less than the length LO and less than the length is LH. The length LB of each spacer 14 is between 40% and 80%, preferably between 55% and 75%, of the length LH of a main section 13.

The base section 7 and the upper head coupling sections 9 as well as the neck coupling sections 10 form a fastener tape.

The base section 7 and the upper head coupling sections 9 as well as the neck coupling sections 10 are formed by a one-piece plastic molded part. The plastic molded part is preferably injection molded.

Each top-head coupling section 9 is connected to a top-head piece of tape 16, for example in a fixed or articulated manner. The top-head tape pieces 16 are firmly connected to one another and, in the assembled state of the interior fittings 2, form an arched top-head arrangement. For example, the top-head band pieces 16 are in a preferably releasable, form-fitting and / or force-fitting connection and can be fixed relative to one another in stages. It is expedient if one upper head piece of tape 16 has a plurality of securing openings arranged one behind the other and the other overhead piece of tape 16 has a securing projection for engaging in a desired securing opening.

A first securing device 22 for securing the interior fittings 2, in particular on the inside, on the helmet shell 1 is arranged in each connection point between an upper head coupling section 9 and the associated upper head band piece 16. There is an essentially right angle between each top-head coupling section 9 and the associated top-head piece of tape 16.

An adjustment piece 17 is pivotably connected to each neck coupling section 10 via a pivot bearing device 18. Each pivot bearing device 18 forms a defined pivot axis, which allows precise pivoting of the respective adjustment piece 17. The adjustment pieces 17 are adjustable in height. The height of the neck arrangement can be adjusted at which the adjustment pieces 17 rest against the neck or back of the head of the wearer.

The two adjustment pieces 17 are part of a neck arrangement and are connected to one another in a variable length via an adjustment device 19. Each adjustment piece 17 carries a toothed strip 20. The adjustment pieces 17 are brought together in the assembled state of the interior fittings 2. The toothed racks 20 face one another at least in some areas. A toothed body (not shown) of the adjusting device 19 engages with the toothed strips 20 and can be pivoted or rotated by means of an actuating wheel 21 to move the adjusting pieces 17 relative to one another and to adjust the size of the interior fittings 2. The actuating wheel 21 is arranged in the neck area or the back of the head area of the interior equipment 2.

The strap continues in the neck arrangement. It forms a circulating belt.

A visor 24 for protecting the face of the wearer is hinged to the front of the helmet shell 1.

In the assembled state, the interior fittings 2 are fixedly connected laterally to the helmet shell 1 via their first fixing devices 22. Furthermore is the interior 2 is firmly connected to the helmet shell 1 at the front via a second fastening device 23 which is arranged in the base section 7. The base section 7 and at least in some areas also each top-head coupling section 9 are immovable with respect to the helmet shell 1.

The base section 7 is located in the front region 3 of the head protection arrangement or the helmet shell 1 and extends perpendicular to the plane of symmetry E, while the neck arrangement is arranged in the rear region 4 of the head protection arrangement or the helmet shell 1. Each upper head coupling section 9 and the base section 7 extend adjacent to a lower edge of the helmet shell 1. The upper head arrangement engages in the head receiving space 6 and extends perpendicular to the plane of symmetry E. It essentially follows the inner contour of the helmet shell 1. The majority of the interior equipment 2 is accommodated in the helmet shell 1. The adjustment pieces 17 run below the helmet shell 1.

When the head protection arrangement is worn, the wearer's head is received in the head receiving space 6. When the head protection arrangement is worn, the wearer's head is only in direct contact with the interior trim 2. The interior trim 2 supports the helmet shell 1 in relation to the head of the wearer and keeps it at a distance from the head of the wearer.

When the head protection arrangement is correctly put on, the base section 7 comes to rest on the forehead of the wearer and forms a headband, while the neck arrangement rests approximately in the middle of the back of the head or neck of the wearer ( Fig. 5 , 6th ). The interior 2 fixes the helmet shell 1 on the head of the wearer. It ensures a stable Hold on to the wearer's head. The pivot axes of the pivot bearing devices 18 run essentially horizontally when the head protection arrangement is properly worn. They are located below the connection points between a respective top-head coupling section 9 and the associated top-head piece of tape 16. The coupling sections 9, 10 extend along a circumferential path that can be adapted to the head.

The effective length of the adjustment pieces 17 can be varied by manually pivoting or rotating the actuating wheel 21. The adjusting pieces 17 can be tensioned by means of a tensioning process, which leads to tensioning of the neck arrangement or of the support band. Tensioning takes place after the head protection arrangement has been put on. The other way around, relaxation is possible. By operating the actuating wheel 21, a head adjustment length of the interior fittings 2 can thus be adjusted overall.

When the size of the interior fittings 2 changes, there is a relative movement between each first securing device 22 and the respective adjacent neck coupling section 10. When the interior fittings 2 or the support strap are reduced in size by actuating the actuating wheel 21, the adjustment pieces 17 slide over one another and the pivot bearing devices 18 approach to each other. A distance between each first fixing device 22 and the adjacent pivot bearing device 18 increases. Each angle W increases. When the interior fittings 2 or the support belt are enlarged by appropriate actuation of the actuating wheel 21, the adjustment pieces 17 move apart and the pivot bearing devices 18 move away from each other. A distance between each first fixing device 22 and the adjacent pivot bearing device 18 decreases. Any angle W decreases. The carrier tape forms a head size adjustment ring with an adjustable system.

Each top-head coupling section 9 and the adjacent main section 13 always extend in the assembled state of the interior trim 2 or in the worn state of the head protection arrangement parallel or essentially parallel to one another. Each neck coupling section 10 always extends further in a circumferential direction 15 of the head protection arrangement than the adjacently arranged top head coupling section 9.
