Description

The invention relates to a receptacle for additional devices for viewing devices according to the preamble of claim 1.

On a headgear, such as a helmet, worn viewing devices are used in particular by military, police and border guards. Such vision devices are, for example, night vision or thermal imaging devices for use in poor visibility or light conditions or in the dark. In order to keep the weight of the mounted on the head vision equipment as low as possible, components that do not need to be provided directly in the viewing device, attached as separate accessories by means of a recording on the helmet and - electrically by means of a cable - and possibly also electronically the vision unit connected. The accessories, for example, provide battery units for powering the viewing device or switching devices, e.g. for switching on and off and regulating the amplifier power of a light amplifier.

In order to compensate the weight of the viewing device - at least partially - with the weight of the accessories, it is customary to position the accessories on the side of the head covering substantially opposite the viewing device. As for the viewing device, a fixed attachment to the headgear is required for the accessories, in order not to give in shakes that occur in particular due to movements of the user.

There are a variety of attachable on a headgear shots for accessories known. The attachment is for example directly, for example by Screw on, on the headgear. A recording of this kind is in the US 5,683,831 described. In the picture shown there, a receiving element is screwed to the helmet. The receiving element has joints, in which joints rails of a battery case are pushed, whereby the battery case is releasably attached to the receiving element. The power supply of the viewing device by means of a guided over the helmet cable.

The disadvantage of such an arrangement proves the fixation of the receiving element on the helmet. As a result, the helmet is not easily replaceable - what, for. damage may be required - or the receiving element can not be easily removed from the helmet - what, for. may be desirable for uses without viewing device for weight reasons. The loose cable routing over the helmet also increases the risk of damage caused by hanging. Furthermore, due to the fixed cable length, an adaptation to different helmet sizes is not possible.

As - without tools, such as tools - detachably mountable on a headgear shots, for example, recordings are known, which are clamped between two sides of the headgear. For this purpose, the recording is attached or fixed on one side of the headgear and stretched to the other side by means of a headband guided over the headband, wherein the tension band is attached or fixed on the other side. The attachment to the headgear is done by lashing the strap on the head covering by means of a clamping lever. The cable is led under the tension band.

In this arrangement, however, the problem often arises that the clamping lever is inadvertently actuated and the connection is thereby released. For example, the unwanted operation is carried out by scrub and branches, or when the user hits his head somewhere. This is also the cable one Danger with respect to hanging, if it is not taut under the strap and hanging out - such as in a tightened strap on a smaller helmet.

To overcome the drawback of the prior art, an object of the present invention is to provide a mountable on a headgear receptacle for accessories for viewing devices, which allows a more compact arrangement on the headgear and thus increased stability and increased comfort. Another, or alternative, object is to provide a headgear-mountable receptacle that reduces the likelihood of accidental release of the fastener. Furthermore, or alternatively, a receptacle that can be used on headgear of different sizes should be provided.

These objects are achieved by a receptacle for additional equipment, in which the characterizing features of claims 1 or the dependent claims are achieved, solved or developed the solutions.

According to the invention, an attachment receptacle is provided with a tensioning device for fastening the receptacle via a tensioning element on a headgear, respectively for forming a retaining connection via the tensioning element. This no longer requires more fasteners on the head covering or on the clamping element. As a result of the design according to the invention, the receptacle, after attachment to the headgear, forms an extremely compact arrangement with the viewing device arranged on the opposite side of the headgear. By both recording and clamping device facing the viewing device, an increased weight balance and thus increased comfort is achieved.

Furthermore, the side of the headgear on which the viewing device is arranged is referred to as the first side or the front side, and the side of the receptacle correspondingly as the second side or the rear side.

The headgear on which the receptacle according to the invention is worn in the position of use, for example, represents a helmet. Likewise, the receptacle on a face mask, as it is known for military applications, or a, e.g. belt-like, carrying frame can be used as headgear.

The tensioning element is for example a plastic or textile strap. It may be multi-part and / or differently shaped areas - e.g. made of different materials, which are preferably mechanically or slightly stretchable - have. In one embodiment of the invention, the clamping element is a two-part strap, wherein the first part is designed as a textile band and the second part as a plastic band with a toothing and the parts are connected together.

For attaching the inventive accessory recording on the headgear at least one fastening component, such as a support plate, and the clamping element is provided, wherein the receptacle with the fastening component and the clamping element, in particular releasably, is connectable. Furthermore, the receiving and clamping element are preferably designed so that the clamping element in or on the receptacle - at least along a clamping range, respectively Verstellbereichs - is displaced, whereby an adaptation of the connection produced via the clamping element is made possible to different headgear sizes. By means of the fastening component, the receptacle on the back of the headgear is set or positioned. About the clamping element a connection to the front and / or the display unit is made. The fastening component is on the back, the clamping element on the front side held the headgear, for example, each by means of hook-shaped brackets. If the receptacle is positioned on the headgear in this way, a firm holding connection is produced via the tensioning element by means of the tensioning device of the receptacle.

For this purpose, the tensioning device has in particular a - e.g. Clamping or clamping-like acting - locking element for locking and possibly clamping the clamping element, so that the clamping element is firmly held in a position in which the recording firmly - substantially non-displaceable - rests on the headgear. A clamping or clamping-like acting locking element can be designed as a conventional clamp or clamp, so that the clamping element can be held in the locked position by clamping or pinching. The fixation on the headgear can be enhanced if the tension element is lashed and tightened by tension. To remove the recording, the locking element is brought out of the locking position, the clamping element released and thus solved the holding connection. With a clamping element displaceable in or on the receptacle, it is possible by displacement, e.g. Pull out, the clamping element, the connection can be further solved. After releasing the connection, the receptacle - optionally in connected to the fastening component and / or the clamping element position - be removed from the headgear.

If the locking element is displaceable along a range, then the clamping element can be lashed by the clamping element by means of the locking element - for example by clamps, clamps or claws - is held, and the locking element is moved by applying a force along the range such that the Connection is made closer. By moving the clamping element is lashed and pressed the receptacle to the headgear. In this position, the clamping element is then determined.

If the clamping device has a locking element, an actuating element for the locking element is preferably also provided. The actuator is e.g. a leverage or tension-type actuator, such as a clamping lever, the clamping device for the locking element, wherein under an operation of the locking element bringing the same is to be understood in the position for locking and releasing the clamping element and optionally in an intermediate position for partial release of the clamping element. With appropriate design of the clamping device can rotate, pivot or pull the actuator cause a force transmission to the locking element.

Does the clamping element locking elements and the locking element latching elements for interacting with the locking elements, respectively engaging in the same, on, so the locking element can engage in the locking elements and moved in the locked position, determined and so the clamping element are lashed. The locking elements are for example a toothing on the clamping element, openings / holes or loops. The latching elements are corresponding to the latching elements, e.g. designed as a ratchet knife, bolt or hook. The tensioning element is, for example, band or rope-shaped, optionally also asymmetrical in shape. Preferably, the clamping element is made of low-stretch material, such as plastic.

By the clamping device is arranged in or on the receptacle, the arrangement can be carried out so that no components protruding or protruding - that the forms of clamping device, or externally accessible parts of the clamping device, such as an actuator, and recording so to speak "merge "- For example, by means of a close fitting to the recording or a cover of the recording forming or integrated into a cover of the recording actuator. In one embodiment of the invention, the receptacle has a tensioning device with a tensioning lever as an actuating element or actuating device, and a housing, wherein the Clamping lever in locking position on the housing fits tightly and is additionally engaged on the housing. With such adapted to each other or in each other mingled outer forms recording as in relation to the attachment to the headgear made extremely secure against displacement, as an arrangement with a substantially uniform surface no or little opportunities to attack from the outside, so an adjustment or release of the recording on or from the headgear is almost impossible due to hanging in or tearing off elements of the recording.

An accessory receptacle according to the invention may comprise further components, e.g. a housing or housing components for receiving the accessories, have. Likewise, the receptacle for attaching housings of the accessories may be formed.

The accessories are integrated or integrated into the receptacle and include an energy source, such as batteries, for powering the viewing device. The electrical connection to the viewing device takes place in particular by means of a guided from the recording to the viewing device cable. The accessories may include other electrical, electronic and mechanical components. Electronic components are e.g. for the processing of signals delivered via interfaces providable. A printed circuit board with SMD components and chips can represent such an electronic component. The chips can be designed, for example, for converting video signals into signals for a display device display. Signals supplied via interfaces, such as plug connectors, may also include GPS signals, e.g. from a pocket computer, or video signals from cameras or thermal imagers.

If the viewing device is a night-vision device, a control unit for a light amplifier of the night-vision device is also preferably provided as an additional device. Optionally, the accessories have components that serve to turn on and off the light amplifier and / or video signal.

If the viewing device is a pair of binoculars with measuring and / or recording functions, then the power supply of a laser, a camera or a computing unit, e.g. for a distance meter, and / or further signals, such as position signals for insertion into the binoculars, are provided.

The optionally used cable for connecting the accessories to the viewing device is designed according to the type and number of additional devices. For power supply is sufficient a power cable. The transmission of several signals can be done with a ribbon cable, respectively interface cable. Optionally, a connection of the accessories to several viewing devices, e.g. by means of several cables, providable. According to the invention, the cable can be guided in the clamping element, whereby a complete protection against environmental influences and hanging is achieved. Furthermore, according to the invention, for a displaceable in the receptacle clamping element, the cable in the receptacle in a loop is guided so that when moving the clamping element in a first direction -. Extracting the clamping element - the loop is unrolled and when moving in the opposite direction - insertion of the clamping element - the clamping element is rolled back into the loop. So the cable can be adjusted with the clamping element, without ever being unprotected.

As previously mentioned, the attachment component for fixing the attachment recording on the headgear in the use position - on the headgear of a user - with the recording medium or immediate, preferably releasably connected. To fix the recording on the headgear, the fastening component is firmly attached to the headgear, eg by means of hooks or alternative contact elements or brackets. For example, the fastening component is designed as a carrying plate with hook-shaped holding straps. For a connection of recording and mounting component, the recording and the mounting component middle or directly corresponding connection partners - such as hooks and slots or guides and rails - have, preferably for connection by a releasable positive connection, such as by snapping, clicking, snapping, insertion or via a detachable screw.

The attachment component can also - be part of the recording - medium or immediate. An immediate part of a receptacle could be, for example, a receiving housing or housing part designed as a fastening component or simply a support plate designed for attaching accessory housings.

For specially designed headgear, the attachment component may optionally form part of the headgear - for example, a helmet with hooks or alternative attachment hardware may be used as attachment component for attachment - e.g. for latching, clicking, insertion or connection via a rotary closure - the receptacle or be formed by corresponding parts of the receptacle. With such an integrated into the headgear fastening component, the recording is determined by the connection with the fastening component on the headgear. It is understood that for such an embodiment the connection should be solvable.

Alternatively, a special headgear can also have attachment parts for attaching the attachment component, such as hooks or alternative attachment parts for attachment - eg, for engagement, click-in, insertion or connection via a twist-lock - the attachment component, which is correspondingly provided with corresponding parts. Thus, the determination of the recording on the headgear is achieved by connecting the fastening component with the headgear over the connecting parts thereof and connecting the receptacle with the fastening component.

Optionally, the fastening component with the headgear be firmly connected, for example by means of screws. A firm connection, however, is a limitation in terms of removing or replacing the attachment component or transferring it to another headgear.

A with respect to an adaptation to different sized headgear improved accessory receptacle is provided with a receptacle which is connected via a connecting element with a fastening component, wherein connecting element and fastening component are formed as mutually differently positionable. The fastening component constitutes one of the previously described alternatives, with the exception of the fastening component as the immediate part of the receptacle. The connecting component is preferably a component of the receptacle, such as a retaining plate or a housing rear wall. The fastening component and connecting element can be positioned relative to one another along an imaginary connecting line, which leads from the back over the middle to the front of the headgear, so that the receptacle on the headgear can be adjusted in height. Such a flexible reception is adaptable, for example, to helmets of different countries, which can differ significantly in their sizes, or to individual needs for weight distribution. Together with a displaceable tensioning element as described above, an even further adaptation range of the auxiliary device receptacle is made possible.

Positionability is achieved via positioning elements. The positioning elements may be separate components and be detachably attachable to the fastening component and connecting element. Likewise, they may be firmly attached or attached or formed as a unit, for example in one piece, with fastening component and connecting element. For example, the fastening component has hook elements and the connecting element slot elements as positioning elements. If the Attached fastening component in the use position on the headgear - or attached - is, the hook elements can be clicked depending on the size of the helmet in the appropriate height in the slot elements. Of course, a plurality of conventional positioning elements, by means of which a connection, in particular by releasable positive connection, for example a snap or locking connection, can be produced, can be used. The connecting element could also be displaceable and fixable in different positions in a rail of the fastening component. In the case of the previously designed special headgear with integrated fastening component, the fastening component can form the positioning elements (eg several slots in or hooks on a helmet). In the case of the special head coverings with connecting parts described above, the connecting parts can represent further positioning elements - thus positioning of the receptacle relative to the head covering is possible by positioning the fastening component relative to the head covering and positioning the connecting element relative to the fastening component.

In Fig. 1 an inventive receptacle for accessories for a viewing device on a helmet 5 is shown as a headgear of a user 1. The viewing device here is a monocular night vision device 2 and positioned in working position with the eyepiece 3 in front of the eye of the user 1. Radiation received by the objective 4 is amplified in a residual light amplifier of the night-vision device 2 and perceived as an amplified image by the observer 1. The attachment of the night-vision device 2 on the head covering is effected by means of a holder 33, which is mounted on retaining bracket 8 at the edge of the helmet front and connected via a strap 6 with the auxiliary device receptacle 10.

The accessory receptacle 10 has a housing 12 in which the accessories are arranged. Controls, such as an image brightness controller 13 and a switch button 16, or an electrical connection 14 are integrated into the housing 12 so that they are accessible from the outside. About a battery cover 15, a battery compartment in the housing 12 is accessible.

The accessory receptacle 10 is connected to a mounting component, which is hung with brackets 9a at the edge of the helmet back. For attachment to the helmet 5, the accessory receptacle 10 is determined by the connection with the fastening component on the helmet 5. The tension band 6 is guided through a housing opening in the accessory receptacle 10. If the tension band 6 is pushed as far as possible into the accessory receptacle 10, it is detected by means of a tensioning device of the accessory receptacle 10, so that the attachment receptacle 10 bears firmly against the helmet 5. In the presentation of the Fig. 1 a clamping lever 11 is shown as an actuating element of the clamping device.

In Fig. 2 are the accessory recording 10 off Fig. 1 and shown various positions of the clamping lever 11 to explain its operation. The clamping lever 11 is mounted on the housing 12 and integrated in its shape so that it fits tightly against the housing 12 and so no significant protruding edges can cause unintentional operation. Shown are the positions of the clamping lever 11 during an operation thereof. In a first position S1, the clamping lever 11 is located directly on the housing 12, in this position, the clamping band 6 is made Fig. 1 determined and fixed the accessory receptacle 10 on the helmet 5. Advantageously, the clamping lever 11 is locked in the first position S1 on the housing 12, so that an accidental operation is further complicated. If the clamping lever 11 is actuated - here by a rotary or pivoting movement - can in an intermediate position SZ the clamping band 6 from Fig. 1 be inserted into the accessory receptacle 10 and is secured against pulling out there. The clamping lever 11 is shown in dashed lines in the intermediate position SZ as a piece. In a second position S2 of the clamping lever 11 - shown dotted in the second position S2 as a piece - the clamping band 6 is made Fig. 1 released and can be removed for disassembly of the accessory holder 10 several centimeters - or possibly completely - out of this.

Fig. 2 also shows the electrical connection 14, for example, to supply the night-vision device 2 with information from other sources such as from radio transmission, data storage or measuring devices, the image brightness controller 13, which is provided for example for controlling the power of the residual light amplifier or for a display in the night-vision device 2, and the switch button 16, which is used to turn on and off the residual light amplifier or other signals, such as video signals, can be trained. Shown are also the battery lid closure 15 of the battery compartment and the headband 9a, 9b of the fastening component.

In the FIGS. 3a to 3c the fastening component and its connection with the accessory receptacle 10 is shown. The fastening component 9 is designed as a support plate 9c with retaining clips 9a, 9b. Furthermore, it has slot elements 26 as positioning elements. The connection with the accessory receptacle takes place via a connecting element 25, which here forms a housing rear wall of the housing 12, wherein the connecting element 25 is connected as a housing rear wall with further housing parts via a screw 28. The connecting element 25 has a plurality of hook elements 27 as positioning elements. By hooking in and clicking in or snapping into different hook positions, coarse adjustment is possible for different sizes of headgear. Shown in Fig. 3a a relative position of fastening component 9 and head cover fastener 25 for small head sizes, in Fig. 3b a relative position for headgear for "medium" head sizes and in Fig. 3c a relative position for headgear for large head sizes. In the illustrated embodiment, three hook and slot elements (27,26) are provided in each case. It goes without saying that the number and design of the positioning elements can be selected as appropriate as an alternative.

Fig. 4 shows a section through the attachment receptacle 10, so that in particular the installation position of the clamping band 6, which is height-displaceable between the connecting element 25 as a housing rear wall and the other housing parts of the housing 12, is clearly visible. In this illustration, the clamping band 6 in a lower position - that is as far as possible in the Attachment holder 10 inserted - shown. As accessories here are the switch button 16, a push button 19, a potentiometer 18, the image brightness controller 13, the electrical connection 14 and an electronic unit 17 shown, the - made of rubbery material - switching button 16 acts on the push button 19 and the image brightness controller 13 - with the potentiometer 18 is connected. Pushbutton 19, potentiometer 18 and electrical connection 14 are electrically connected to the electronic unit 17, such as a printed circuit board. Other mechanical components, such as the arrangement or attachment for the controls are not described. On the electronic unit 17, a cable 23 is connected, by means of which the electronic unit 17 electrically and electronically to the night-vision device 2 from Fig. 1 is attachable. The cable 23 is guided in the accessory receptacle 10 through a grommet 24 through an electronics cover 22, which is used for waterproof separation between the strap 6 and the electrical and electronic accessories in the accessory receptacle 10. The cable 23 is further guided in the attachment receptacle 10 in a loop around the tension band 6, so that a withdrawal of the tension band 6 is easily possible without the cable 23 to injure or buckling. As a result, the cable 23 runs along the tensioning band 6 and is thus completely covered and protected in the area of the headgear against the risk of injury from the tensioning band 6. In the example shown as a ribbon cable 23 here both the power and several possible data lines are housed. Batteries 34 (see Fig. 5 ) as an energy source can be inserted into a battery compartment of the auxiliary device receptacle 10 or removed therefrom. To open and close the battery compartment is a battery cover 20 via a seal 21 on the housing 12. With a rotatable battery lid closure 15 which is rotatably connected to a lock 15b by means of screw 15a, the battery compartment cover 20 is held via an undercut in the housing 12 depending on the rotational position of the battery lid closure 15 or released for opening.

In Figure 5 the tension band 6 and its arrangement or guidance in the accessory receptacle 10 is shown in more detail. To illustrate the tension band 6 in the recording are in Fig. 5 Housing parts hidden. The tension band 6 is composed of a first tension band part 6a and a second tension band part 6b. The first strap portion 6a is in the position of use on the headgear, such as the helmet 5 (see. Fig. 1 ) and is made for example of textile fabric or a hose-like rubber-like material. The second tension band part 6b is here made of plastic and centrally has a cable channel 38 for the cable 23 Fig. 4 on, which largely encloses the cable 23. The cable 23 may advantageously be guided to the sighting device in the tensioning band 6 (in a cable channel both in the first and in the second tensioning band part 6a, 6b), for example in a shell through an opening through the tensioning band 6 or a tension band 6 - for example Plastic - illustrated cable duct. The guide can also take place within the second tension band part 6b and below the first tension band part 6a. The second clamping band part 6b has right and left of the cable channel 38 along a clamping portion 6b 'locking elements each in the form of a toothing 30a, 30b. The clamping region 6b 'defines the region of the tension band 6 - or here the second tension band part 6b - which is fully slidable into the accessory receptacle 10. The connection of the two clamping band parts via a flange-like ausgestaltetes connecting part 36, which may be provided on the first or second clamping band part 6a, 6b. The connection of the two materials of the two clamping band parts can be done by rivets or screws. Of course, just as an alternative conventional connection can be selected.

Out Fig. 5 is also the guidance of the tension band 6 in the accessory receptacle 10 hinted at. This has along the connecting element 25 on the right and left guides 37, by means of which the clamping band 6 is guided laterally exactly. Also shown are attachments of the accessory receptacle 10, as they are arranged in the use position. The mounted on the electronics unit 17 components push-button 19, Potentiometer 18, and electrical connection 14 are arranged centrally. Arranged on the outer sides are batteries 34, which are connected via resilient battery contacts 35 to the electronic unit 17. The interconnection of the other two battery contacts is housed in the battery lid in a conventional manner and not shown here. The electronics cover 22 is disposed between the strap 6 and the electrical and electronic accessories.

For recognizable representation of the clamping device of the auxiliary device holder 10 are in Fig. 6 several elements hidden. Shown is the connection component 25 with guides 37 and guided in the guides 37 tension band 6. The clamping band 6 is slidable along the clamping portion 6b 'in the guides 37 from an initial position to an end position. The starting position may be the position in which the clamping region 6b 'is located minimally in the auxiliary device receptacle 10, that is to say it has been pulled out to the maximum extent. The complete withdrawal from the accessory receptacle 10 may be possible. Optionally, the complete withdrawal but also - for example by means of a stop element - are prevented, so that a complete separation from the strap 6 is avoided, so that the attachment receptacle 10 never only on the cable 23 (see. Fig. 4 ) hangs. The term "end position" is to be understood as meaning the position in which the entire clamping region 6b 'is pushed into the auxiliary device receptacle 10.

The clamping device comprises the actuating element designed as a tensioning lever 11. By means of the clamping lever 11 is designed as a latch 29 locking element of the clamping device can be brought into a plurality of positions. The pawl 29 has guide surfaces 45a, 45b and pawl blades 44a, 44b, wherein the pawls 44a, 44b designed as corresponding to the teeth 30a, 30b latching elements in the clamping portion 6b 'of the second clamping band portion 6b by engaging latching elements to the teeth 30a , 30b. Of course, the action of the gears 30a, 30b and the pawls 44a, 44b can be as well along with a toothing of the clamping region 6b 'and a pawl blade - the embodiment of the embodiment shown with two toothings 30a, 30b and pawl blades 44a, 44b results from the design of the cable duct. Furthermore, embodiments with right or left along the clamping portion 6b 'guided toothing and corresponding latching and optionally corresponding left or right guided cable channel would be.

The tensioning lever 11 is connected via pivot members 40 in bearings 41 - e.g. correspondingly executed recesses - rotatably mounted by the connecting element 25 formed housing rear wall. Of course, the bearing of the tensioning lever 11 could also take place elsewhere (for example in side surfaces of a housing). The pivot bearing elements 40 are on the one hand firmly connected to the clamping lever 11 and on the other hand by means of pins 42 eccentrically connected to the axis of rotation of the clamping lever 11 with connecting rods 39 rotatably. The pawl 29 or the pawl blades 44a, 44b is or are rotatably supported via armpit elements 43 in the connecting rod 39. Thus, in a known manner, a rotational movement of the clamping lever 11 via the connecting rod 39 as a force transmission element in a displacement of the pawl 29 and thus also the pawl 44 a, 44 b implemented.

The displacement of the pawl 29 is also still controlled by the guide surfaces 45a, 45b. The control takes place in cooperation with the guides 37 of the connecting element 25, in particular with slide-like guide elements 31 of the guides 37. With continuous rotation of the clamping lever 11 about the axis of rotation is moved due to the eccentric arrangement of the pins 42 to the axis of rotation, the pawl 29 via the connecting rod 39. When turning the clamping lever 11 in the second position S2 - as in Fig. 2 shown - the guide surfaces 45 of the pawl 29 are pushed onto the backdrop-like guide elements 31, whereby the - pawls 44a, 44b lifted and a complete release of the tension band 6 is achieved. The operation is explained in more detail in the following figures.

If the clamping lever is moved from the second position S2 to the first position S1, the pawl 29 is moved downward, the pawl blades 44a, 44b engage in the sawtooth-like teeth 30a, 30b and push the latch lever 11 as the pawl 11 advances Tightening strap 6 down, which causes a lashing of the tension band 6.

In the intermediate position SZ the pawls are 44a, 44b on the teeth, so that the clamping band 6 can be pushed down, pushing upwards - in the direction of the sight - but is blocked by the pawls 44a, 44b. In order to press the pawl blades 44a, 44b against the clamping region 6b 'or the toothings 30a, 30b, a leaf spring 46 is mounted in the auxiliary device receptacle 10 - for example on a housing part, not shown.

In the FIGS. 7a and 7b is shown in a detailed view of the tension band 6 in the attachment receptacle and the interaction of a pawl knife 44b of the pawl 29 with a toothing 30b of the tension band 6. In Fig. 7a is the pawl knife 44b on the tooth back of the toothing 30b - which ratchet position of the intermediate position SZ of the clamping lever 11 from Fig. 2 equivalent. By the sawtooth-like configuration of the teeth 30b, the clamping band 6 can be moved without resistance down, with each tooth, the pawl 29 secures the strap 6 against withdrawal. When setting the clamping lever in the first position S1 off Fig. 2 the pawl knife 44b dips accordingly Fig. 7b in the toothing 30b, so that the holding connection is made on the headgear. By operating the clamping lever 11 from the second position P2 to the first position P1, as shown in FIG Fig. 2 , a movement of the pawl 29 in the vertical direction, whereby the clamping band 6 is moved by means of pawl knife 44b down and thereby lashed.

In this way, a simple mounting of the accessory recording on the headgear is possible. The clamping band 6 can at the first position S1 or the intermediate position SZ of the clamping lever 11 (according Fig. 2 ) are pushed manually into the accessory holder. The movement of the lever from the first position S1 to the second position S2 causes the engagement in the toothings 30a, 30b (FIG. Fig. 6 ) and shifting the pawls 44a, 44b ( Fig. 6 ) down so that the tensioned over the headgear strap tightened and the accessory receptacle 10 is pressed firmly to the headgear (see. Fig. 1 ).

The FIGS. 8a to 8c show in section detail views of the positions of the pawl 29 when moving the same in the guides 37 of the accessory recording. The guides comprise a backdrop-like guide element 31. Shown is the pawl 29 with the pawl 44 b and its guide surface 45 b. The guide surface 45b has a cam 32b which, depending on the position of the clamping lever 11 (see FIG. Fig. 2 ) determines the stop position of the pawl 29 (correspondingly, the guide surface 45a from Fig. 6 a cam 32a).

The FIGS. 8a and 8b show the position of the pawl 29 at the position of the clamping lever in the first position S1 and the intermediate position SZ as shown in FIG Fig. 2 , When adjusting the clamping lever to the intermediate position SZ, the guide surface 45b is displaced in the guide 37 along a region B to the backdrop-like guide member 31. In this area B, the pawl knife 44b of the pawl 29 can dive into the toothing of the tension band, so that the pawl 29 secures the tension band in every position against pulling out.

Fig. 8c shows the pawl 29 in the second position S2 of the clamping lever as shown in FIG Fig. 2 , When the tension lever is moved to the second position S2, the guide surface 45b is slid onto the slide-like guide element 31. The pawl 29 is thereby forcibly rotated by the cam 32 - in the representation counterclockwise - so that the pawl knife 44 b can not dive into the teeth of the tension band. As a result, in this position, the holding of the tension band is prevented by the pawl 44 b, whereby the tension band can be pulled out, so that the accessory receptacle is removable from the headgear.
