As an introduction, it should be noted that in the differently described embodiments same parts with the same reference numerals or same component names provided with the disclosures contained throughout the description analogously to the same parts with the same reference numerals or the same Component designations can be transferred. They are also in the description selected location information, such as top, bottom, side, etc. to the one described immediately as well as shown figure and are analogous to a change in position to transfer to the new situation. Furthermore, individual features from the different exemplary embodiments shown for independent, represent solutions according to the invention.

In Fig. 1, a fireman 1 is shown, the one as personal protective equipment Helmet 2 and a respirator 3 wearing a respirator 4, which Breathing apparatus has 4 bottles 5, in which the breathing air is under high pressure is saved. The personal protective equipment of fireman 1 is used to to make it independent of the ambient air, so that, as in the present embodiment shown fighting a fire with a jet pipe 6 also in an atmosphere enriched with poisonous gases and possibly also low in oxygen becomes possible.

The strapless respirator 3 is connected to the device 7 Hard hat 2 connected and consists of two coupling devices 8 and 9, of which one is attached to the protective helmet 2 and the other to the breathing mask 3. The respiratory mask 3 further comprises a viewing window 10, a mounting frame 11 for this viewing window 10 and a sealing edge 12 with which a sealing Termination between the respirator 3 and a face 13 of the fireman 1 is manufactured. The breathing air from the bottles 5 is dosed via a regulator 14. The loading of the regulator 14 with compressed air The bottles 5 can be controlled via a control valve 15. For this is the Regulator 14 connected to the control valve 15 via a line 16.

Of course, it is possible for the fireman 1 to have only one bottle 5 Breathing air or several bottles 5 with breathing air carries with him. Furthermore, it is also possible that instead of the container devices used regeneration or circulation devices become. It is also irrelevant to the present invention whether normal pressure breathing apparatus can be used with regulator 14 or overpressure systems.

2 to 4 is the protective helmet 2 and the connection devices 7 associated with this mask 3 shown in detail.

The protective helmet 2 comprises a protective helmet shell 17, in which a support frame 18 for adaptation to the different head dimensions of users, especially of Firefighters 1 is arranged. A head width of the support frame 18 can by an adjusting device 19 can be set. On the support frame 18 is in the flank area 20 of the protective helmet 2, a support plate 21, for example fastened via rivets 22, which, as can be seen better from FIG. 4, has a pivot axis 23 Joint arrangement 24 for holding a helmet-side first and second coupling part 25 of the connecting devices 7, in the present case by a locking band 26 are formed, as well as an axis of rotation 27 about which a chin strap 28 can be rotated. In the illustrated embodiment, however, only the first coupling part 25 of the connecting device 7 can be seen. The second coupling part 25 of the connecting device 7 is in turn via a pivot axis 23 of the further flank area 20 of the protective helmet 2 rotatably mounted.

A visor 29 is also arranged around this pivot axis 23 a rest position shown in full lines in Figs. 2 and 4 within an interior 30, which is enclosed by the protective helmet shell 17, in a dashed Lines shown working position can be swung out.

This visor 29 is predominantly used without the one at a distance from the protective helmet 2 shown respirator 3 thought. However, it is also possible with appropriate Design of the visor 29 and the respirator 3 these together to use.

The respiratory mask 3 comprises the viewing window 10, which is in the mounting frame 11 is supported. At the support frame 11, the sealing edge 12 connects to the sealing end of the breathing mask 3 between this and the face 13 of the User serves. On the mounting frame 11 for the viewing window 10 is a helmet-side first and second coupling part 25 corresponding first and second coupling part 31 of the respiratory mask 3 in the present case, for example a clasp, in particular a latch clasp 32, arranged.

In order to optimally adapt the respiratory mask 3 to the respective user reach, the first and second coupling part 31 is also about a pivot axis 33 with the mounting frame 11 or a support plate arranged on the sealing edge 12 articulated and thus rotatably connected.

The corresponding coupling part 25 assigned to this coupling part 31 exists in the present case from the locking band 26, which is tensile but flexible. In the end portion facing the coupling part 31 has this locking band 26 in a small amount Positioning elements arranged one behind the other, in particular detents 34 provided. These point in the direction of the pivot axis 33 of the respiratory mask 3 an obliquely rising flank, while that of the protective helmet shell 17 or the swivel axis 22 facing locking flanks substantially perpendicular to the Surface of the locking band 26 are aligned.

In the illustrated embodiment, the ears of the user facing flank areas 20 of the helmet-side first and second coupling parts 25 supported in a tensile and shear-resistant manner on the supporting frame 18. Furthermore, the protective helmet 2 a further connecting device 35, which in the area of the forehead 36 of the user, firefighter 1 in particular, is assigned to. The other in the field of Forehead 36 arranged further connection device 35 is in turn by a helmet-side third coupling part 37 of the further connecting device of the Protective helmet 2 and a corresponding third respiratory protection side Coupling part 38 formed. The third coupling part 37 on the helmet side is secured by a latching element, in particular a locking band 39 is formed, whereas the third on the respiratory protection side Coupling part 38, via a corresponding locking element, in particular a locking clasp 40 is formed.

The latch clasp 40 is in turn on the mounting frame 11 for the viewing window 10 the breathing mask 3 is arranged, which in turn over a pivot axis 41 can be rotatably mounted. It is advantageous here that an arrangement Pivot axis 41 for the latch clasp 40 is designed to be rotatable only to a limited extent is, so can only be pivoted over a certain angular range, as a result a rotation of the locking clasp 40 is prevented by 180 °, so that incorrect coupling of the two coupling parts 37, 38 is prevented.

The helmet-side third coupling part 37 is on the support frame 18 of the protective helmet 2 and stored pressure-resistant or shear-resistant. For this it is possible that the helmet-side coupling part 37 is firmly connected to the support frame 18. Of course it is possible as shown in the illustrated embodiment that the third coupling part 37 is mounted on the support frame 18 via a pivot axis 42. Furthermore, it is possible that, for example, the helmet-side coupling part 37 for connecting to the Support frame 18 of the protective helmet 2 is formed with a support plate 43, so that the third clutch part 38 on the respiratory protection side has a stable contact surface on the support plate 43 receives. The arrangement of the support plate 43 ensures exact guidance of the others Connection device 35 when pushing the two coupling parts 37 together, 38 reached, so that pressure points on the face 13 of the user are prevented. Furthermore it is possible that the support plate 43 have guide webs for the locking clasp 40 can.

The arrangement of the pivot axis 42 for the coupling part 37 also makes it possible to that this from a coupling position shown, as shown in Fig. 4, in the interior 30 of the protective helmet 2 can be pivoted in, so that the user when wearing the protective helmet 2 without the respirator 3 not from that in the area the forehead 36 arranged coupling part 37 is disturbed or hindered. It is also possible that when pivoting the coupling part 37 out of the interior 30th this snaps into a locking device, so that when connecting the respirator 3 with the protective helmet 2 prevents the helmet-side coupling part 37 from rotating becomes. The locking device can for example be designed such that the Coupling part 37 has 43 projections in the direction of the support plate, which then with a rotary movement from the interior 30 of the protective helmet 2 in the direction of the shown Connection position through increased effort in the corresponding for the projections Snap or snap recesses in the support plate 43, thereby a simple fixation for the helmet-side third coupling part 37 is achieved. The third clutch part 37 on the helmet side, in turn, has the same as that in FIGS Flank regions 20 arranged first and second coupling parts 25, Positioning elements, in particular catches 34.

In the illustrated embodiment, all the connecting devices 7, 35, in particular their coupling parts 25, 31, 37, 38, by locking strips 26, 39 with the there detents 34 and formed by corresponding locking clasps 32, 40. Furthermore, the helmet-side coupling parts 25, 37 of the connecting devices 7, 35 in a plane perpendicular to the associated pivot axes 22, 42 adjustable relative to the outside of the protective helmet 2, i.e. the coupling parts on the helmet side 25, 37 from within the interior 30 of the protective helmet 2 Rest position in an outer boundary 44 of the protective helmet shell 17 lying rest position or connection point are adjustably mounted.

With such an arrangement it is advantageously achieved that the connection the breathing mask 3 with the protective helmet 2, in particular the individual coupling parts 25, 31, 37, 38 with each other, is easily possible because the user, in particular the fireman 1, with his hands lightly on the individual parts of the connecting devices 7, 35 can get close and therefore a simple one Snap connection devices 7, 35 is guaranteed. At the same time the user the possibility of the individual helmet-side coupling parts 25, 37 in To see the corner of the eye so that due to the detection of the position of the coupling parts 25, 37 a quick and safe fitting or connecting of the respiratory mask 3 with the protective helmet 2 is possible.

In such connection devices 7, 35 ratchet clasp 32, 40 ratchets when Insert the locking band 26, 39 upwards over the oblique flanks and snaps behind the locking flank. The respiratory mask 3 can accordingly the respective shape of the face 13 with sufficient pressure on the face 13 are pressed so that after completion of the face 13 on the Respirator 3 exerted pressure to adjust the respirator 3 this is firmly attached to the protective helmet 2 and thus with its sealing edge 12 sealing on Face 13 of the fireman 1 is present. By snapping the Coupling parts 25, 31, 37, 38 can be the breathing mask 3 in the protective helmet 2 opposite direction from this without actuating the locking clasps Loosen 32, 40. Firefighter 1 has the feeling that the respirator 3 sits too loosely, he only needs the breathing mask 3 even more against press the protective helmet 2, which makes it easy to readjust the respirator 3 is possible.

The arrangement of the further connecting device 35 in the region of the forehead 36 it is now possible for the user to first wear the breathing mask 3 with the other Connecting device 35, that is, the two coupling parts 37, 38, by light Pressing together connects so that the breathing mask 3 roughly on the hard hat 2 is attached. The user then guides those arranged in the flank region 20 Coupling parts 25, 31 together and can then by fixed pressure press the face mask 3 firmly onto the face 13 onto the face mask 3.

By engaging the additional connecting device 35 it is achieved that the further connecting device 35 a kind of guide for those arranged in the flank region 20 Connecting devices 7 forms, i.e. that the first time the respirator comes into contact 3 with the protective helmet 2 these in an exact position to those in the flank area 20 of the protective helmet 2 arranged connecting devices 7, whereby a simple threading of the helmet-side coupling part 25 with the Respiratory mask 3 arranged coupling part 31 is given.

This solution also ensures that the user, especially the Firefighter 1, if the breathing mask 3 is not required, this already on Protective helmet 2 can fix without doing an airtight seal on the edge of the seal 12 with the face 13 of the fireman 1, so that the breathing air is not required by the respiratory protection device 4 since the breathing air enters the interior from the side the respirator 3 can penetrate. Through the so-called three-point bracket the respiratory mask 3 is in the by the connecting devices 7, 35th held predetermined position, whereas with a two-point holder of the respirator 3 due to their weight and the rotatable mounting of the Coupling parts 25 drops in the direction of the body of the fireman 1. It is afterwards necessary for the fireman 1 to use the breathing apparatus 4 must perform, he can simply by applying the respirator 3 with Press this against the face 13, which means that it is ready for use quickly the fireman 1 is given.

Likewise, it is also possible to quickly remove the respiratory mask 3 from the face 13 to remove the fireman 1 because only by simultaneously pressing the arranged to release the connecting device 7, 35 in the latch clasp 32, 40 Push button the connecting devices 7, 35 can be easily released, whereby the locking connection between the locking clasp 32, 40 and the locking band 26, 39 lifted and the respiratory mask 3 removed in the direction away from the protective helmet 2 can be.

When the breathing mask 3 is released from the protective helmet 2, it is possible for the user now by simply pressing the pushbutton for those in the flank region 20 Arranged locking clasps 32 release the sealing end of the respiratory mask 3 or can separate the two coupling parts 25, 31, i.e. that by actuation the push button of the locking clasp 32 the user in the form of a curve movement removes the sealing end of the respiratory mask 3 from the face 13, so that breathing air between the sealing edge 12 and the face 13 into the interior the respirator 3 can flow. The fulcrum when swiveling is formed via the further connecting device 35, i.e. that the coupling part 37 of the further connecting device 35 is designed to be resilient, so that one corresponding rotary movement of the respirator 3 to release the two coupling parts 25, 31 can be performed.

It is also possible for the user to wear the respiratory mask 3 only slightly Face 13 loosens, so that again when the respirator mask 3 is used again quick attachment is possible. Of course, it is possible that a complete It is possible to remove the respiratory mask 3 from the face 13, with this being the case the user in turn first the connecting device arranged in the flank region 20 7 releases and then by simply pressing the push button on the Snap clasp 40 completely separates the respiratory mask 3 from the protective helmet 2.

Of course, it is possible that the additional connecting device 35, in particular the coupling part 37 arranged in the region of the forehead 36 with an articulated arrangement is designed so that a simple pivoting movement can be carried out can and at the same time the coupling part 37 can be rigid. It is also possible that the user when loosening the respirator 3 first the other Connection device 35 releases, so that a pivoting movement in the direction of the body of the fireman 1 can be performed, which in turn the sealing Completion of the respirator 3 against the face 13 is lifted.

With such a construction of a helmet-mask combination it is advantageous that through the arrangement of locking bands 26, 39 a variable adjustment of the distance between the respirator 3 and the protective helmet 2 is possible, whereby a Adaptation of the respiratory mask 3 to the different faces 13 of different ones Users can be done.

As can also be seen from the illustration, in particular in FIG. 3, the respirator mask 3 so arranged on the face 13 of the fireman 1 that the sealing edge 12 between the face 13 and a helmet band 45 of the support frame 18 comes to lie.

Before the respirator 3 is put on, the setting device 19 can be used Diameter of the support frame 18 are increased so that the sealing edge 12 between the helmet band 45 can be inserted, whereupon the tight fit of the Protective helmet 2 the diameter of the support frame 18 with the adjusting device 19th can be tightened again as far as this ensures that the protective helmet 2 is firmly seated on the head of the fireman 1 is necessary. Of course it is possible that with a special design of the sealing edge 12, this below the helmet band 45 ends, so that the setting of the protective helmet 2 does not have to be changed.

From Fig. 4 it can also be seen that the interior of the protective helmet 2 is a support net 46 includes, which by means of adjusting bands 47 in height compared to Helmet band 45 can be fixed.

The coupling part 25, namely the locking band, is on the helmet band 45 via the support plate 21 26 rotatably mounted about the pivot axis 23, with 36 in the region of the forehead the coupling part 37, in particular the locking band 39, with the helmet band 45 directly or is connected via a fastening plate 48 arranged on the helmet band 45.

Furthermore, a neck cushion 49 is arranged on the helmet band 45 of the support frame 18 allow a firm fit of the protective helmet 2 and at the same time the effect of injury should turn off in the event of blows to the protective helmet 2.

A reinforcing element can face the protective helmet shell 17 in the apex area 50 may be arranged, which also, for example, a structure-borne sound microphone Can record radio system.

5 and 6 is a further embodiment for attaching the respirator 3 shown on safety helmet 2.

In addition to the respective flank areas 20 located opposite one another and the area of the forehead 36 of the protective helmet 2 arranged connecting devices 7.35, of which only the coupling part 25 of the connecting device in FIGS. 1 to 4 7 in the flank area 20 of the protective helmet 2 can be seen in the illustrated Safety helmet 2 according to FIGS. 5 and 6 an additional connecting device 51 provided, these by a fourth and fifth coupling part 52, 53 of Protective helmet 2 and a corresponding fourth and fifth coupling part 54 the breathing mask 3 is formed. The helmet-side coupling parts 52, 53 are again formed by a locking band 55, 56. The corresponding coupling parts 54 on the respiratory protection mask 3 are designed as corresponding snap closures 57, these in turn on the mounting frame 11 of the respirator 3 and are pressure-resistant or shear-proof attached.

The locking clasps 57 are now in the area of the chin 58 of a user between the locking clasps 32, which are positioned in the area of the eyes 59, and one Holding device 60 for the regulator 14 is rotatably arranged. On the breathing mask 3 is in turn in the region of the forehead 36 of the coupling part 38, in particular the latch clasp 40, as mentioned in the previously described figures, arranged.

Of course, it is possible that the mask-side coupling parts 54 of the additional Connecting device 51, in particular the latch clasp 57, in the Areas of the respiratory mask 3 facing a user are preferred are pivotally attached to an axis perpendicular to the mask cheek.

The additional coupling parts 52, 53 arranged on the helmet side are in the region of a Neck 61 of the protective helmet 2 connected to the support frame 18. The coupling parts 52, 53, in particular the locking band 55, 56, are elastic, in particular flexible Retaining strap 62, 63, as shown in Fig. 6 with dashed lines, with a preferred U-shaped and continuous clamping element, in particular one Coupling housing 64, connected. The clutch housing 64 is about a pivot axis 65 rotatably mounted on a swivel arm 66. The swivel arm 66 can be any be connected to the support frame 18 in the region of the neck 61. Is preferred the swivel arm 66 in the region of the neck cushion 49, that is to say on a holding device 67 for the neck cushion 49, rotatably mounted about a pivot axis 68, whereby via the pivot axis 68 running approximately perpendicular to the protective helmet shell 17 the vertically pivotable vertical swivel arm 66, the clamping element, in particular the clutch housing 64, via the swivel arm 68 into one within the outer boundary 44 of the protective helmet 2 lying rest position can be swung up. The holding device 67 for the neck pad 49 is in turn attached to the support frame 18.

With such a design of the additional connecting device 51, it is now possible that the respirator 3 with a five-point bracket Hard hat 2 can be attached. The formation of the additional connecting device 51, in particular the coupling parts 52, 53 with the flexible holding band 62, 63, has the advantage that the firefighter 1 prefers the locking tapes 55, 56 from the U-shaped coupling housing 64 when the additional connecting device is pivoted out 51 from the interior 30 of the protective helmet 2 and on the side Head to the respirator 3 can pull forward so that this with the corresponding Coupling parts 54 of the respiratory mask 3 can be connected.

The design of the clutch housing 64 has the advantage that when not in use the additional connecting device 51, the flexible tether 62, 63 in an interior 69 of the clutch housing 64 is drawn in automatically, so that subsequently the locking band 55, 56 can in turn be inserted into the interior 69. For this purpose, it is possible, for example, to hold the locking band 55, 56 better to achieve on the clutch housing 64 that the locking band 55, 56 a clamping device 70, so that by inserting the locking band 55, 56 into the interior 69 the tensioner 70 is deformed so that a pressure on the surfaces of the clutch housing 64 is exercised and thus an independent fall out of the interior 69 is prevented.

In the illustrated embodiment, it is possible that the helmet-side additional Connecting device 51, in particular the coupling parts 52, 53, through the Arrangement of the pivot axes 65, 68 can be pivoted into the interior 30, so that the user through the helmet-side additional connecting device 51 does not is hindered.

So that the user now attach the respiratory mask 3 to the protective helmet 2 , it is possible that, as explained in the figures described above, the respiratory mask 3 first the further connecting device 35 in the area of Forehead 36 is hooked in and then arranged in the flank region 20 Connection devices 7 are connected, then the user the breathing mask 3 presses firmly against the face 13. The user can then the coupling parts 52, 53 arranged in the region of the neck 61 from their rest position remove from the interior 69 of the clutch housing 64 and with the corresponding Attach coupling parts 54 to the respiratory mask 3, so that a corresponding one Train of the respirator 3 is generated in the direction of the chin 58. Of course it is possible that before the breathing mask 3 is pressed against the Face 13 of the user, the further coupling parts 52, 53 with the corresponding ones Coupling parts 54 are connected, so that subsequently by pressing the Respirator 3 on the face 13 of the user a smooth pull over the Five-point bracket is reached. It should be noted that the area of the neck 61 arranged coupling parts 52, 53 or the associated Pivot axis 65 with respect to the pivot axes 23 in the flank regions 20 arranged coupling parts 25 in the direction of the helmet rim, in particular the outer boundary 44, have a greater distance from the support frame 18.

The advantage of a five-point mounting of the respiratory mask 3 on the protective helmet 2 is in that by the special distribution of the coupling parts 31, 38, 54 on the respirator 3 in the area of the forehead 16, the eyes 59 and the chin 58 a uniform Train on the respirator 3 is formed in the direction of the protective helmet 2, so that a secure sealing of the sealing edge 12 on the face 13 of the fireman 1 arises.

Of course, it is possible that in the illustrated embodiment additional connecting device 51, in particular the clutch housing 64, through two separate clutch housings 64 are formed for one clutch part 52, 53 each can be. It is also possible that the flexible tether 62, 63 directly on the swivel arm 66 is attached. It is also possible that the protective helmet 2 only with the connecting devices 7 and 51 or the connecting devices 35, 51 can be, whereby a four-point bracket or a three-point bracket of the Respiratory mask 3 reached on protective helmet 2 and still sealing the edge of the seal 12 is achieved. For this purpose, it has proven to be advantageous for the four-point bracket the respirator 3 the coupling parts arranged in the flank region 20 25 only over a partial area, i.e. over a predetermined swivel angle, can be pivoted, creating a smooth train of Connection device 7 and 51 achieved in the direction of the face 13 of the user will, because of the limited rotational movement towards the firefighter's body 1 resulting train movement through the additional connecting device 51 is prevented.

7 shows a further exemplary embodiment of a five-point holder for the respiratory mask 3 shown on safety helmet 2.

In this embodiment, the coupling parts 25, 37 are again in the area the forehead 36 and in the flank region 20 of the protective helmet 2, as in those previously described Figures shown, arranged. The additional connecting device 51, in particular the coupling parts 52, 53 are in the region of the neck 61, as in FIGS. 5 and 6 described, attached. The coupling part 52, 53 is in turn with the flexible tether 62, 63 connected, the flexible tether 62, 63 now not in one Coupling housing 64, but is attached directly to the swivel arm 66. The flexible Retaining strap 62, 63 can in turn around the pivot axis 65 with the pivot arm 66 are attached.

Furthermore, the protective helmet 2 now points in the interior 30 of the protective helmet shell 17 one for the two coupling parts 52, 53 arranged in the flank region 20 71 on. The receiving device 71 is designed such that the Coupling part 52, 53 can be inserted into the receiving device 71, whereby an independent holding of the coupling part 52, 53, in particular the locking band 55, 56. It is also possible that to hold the coupling part 52, 53 in the receiving device 71 on the coupling part 52, 53, in particular in the area the notches 34, the tensioning device 70 can be arranged. By such Training it is now possible that the user when not using the coupling parts 52, 53 these can be inserted into the receiving device 71, thereby creating an unhindered Working with the protective helmet 2 is given.

The fireman 1 needs the individual to work with the respiratory mask 3 on the protective helmet 2 arranged coupling parts 25, 37, 52, 53, so he can swing out the interior 30 of the protective helmet 2, whereby for the coupling parts 52, 53 the user pulls this out of the receiving device 71 and then with the corresponding coupling parts 54 of the breathing mask 3 via the flexible Tether 62, 63 can connect.

The advantage of such a solution is that the arrangement of a receiving device 71 in the interior 30 of the protective helmet 2 by the user Arrangement or attachment is not hindered at work, although easy handling by simply pulling out the coupling parts 52, 53 is given from the receiving device 71. It is also possible that the cradle 71 at any point on the protective helmet 2, such as in Area of the neck 61 can be arranged.

8 and 9 is a further embodiment of an attachment of the respirator 3 with the protective helmet 2 over the differently positioned connecting devices 7, 35, 51.

The individual connecting devices 7, 35, 51, in particular their helmet-side Coupling parts 25, 37, 52 and 53 are in turn in the area of the forehead 36 in the flank area 20 and arranged in the area of the neck 61 in the interior 30 of the protective helmet 2, the corresponding coupling parts 31, 38 and 54 on the respirator 3, in particular on the mounting frame 11 of the viewing window 10, as in the 5 and 6 are described, attached.

In the illustrated embodiment, however, the individual helmet-side Coupling parts 25, 37, 52 and 53 no longer directly on the support frame 18 of the protective helmet 2, but are via a separate holding frame 72, as can be seen better in FIG. 9, interconnected, i.e. that the individual coupling parts 25, 37, 52 and 53 via a base support band 73 and a support band 74 in the form of the support frame 18 are connected or held. The individual parts on the holding frame 72 which is required for pivoting or fastening the coupling parts 25, 37, 52 and 53 are arranged, i.e., that in the flank area 20 for fastening the coupling parts 25 required support plate 21 is fastened to the base strap 73. In the area of the neck 61 is the holding device 67 with the swivel arm arranged thereon 66 and, for example, the clutch housing 64 attached. In the area of the forehead 36 is the support plate 43 for fastening the coupling part 37 to the basic tether 73 connected.

It is also possible for at least part of the holding frame 72 or the supporting frame 18 stores or forms a headband of the protective helmet 2.

So that the respiratory mask 3 with the protective helmet 2 over the individual connecting devices 7, 35 and 51 can be connected, the holding frame 72nd attached to the support frame 18. For this purpose, the holding frame 72 has fastening means 75 on. The fastening means 75 can, for example, by means of a Velcro fastener 76, Rivets, adhesive layers or snap connections are formed. In the illustrated The fastening means 75 are embodied by a Velcro fastener 76 formed so that the support frame 72 with the support frame 18 in a simple form easy to attach and press down.

If the user now has the holding frame 72 on the supporting frame 18 of the protective helmet 2, 8, attached, it is possible that the respirator 3 with the Protective helmet 2, as already described in FIGS. 1 to 7 described above, can be attached without a respirator 3 with straps such as are known from the prior art, must be used.

The advantage of this embodiment is that when the Protective helmet 2 by a blow, such as in fire fighting due to falling objects, the protective helmet 2 is too high Can release pressure or too high impact from the support frame 72 without that the breathing mask 3 detaches from the face 13 of the fireman 1 and thus the sealing closure between the sealing edge 12 and the face 13 is maintained. Due to the design of the support frame 72 by the Basic tether 73, the support band 74 and the chin strap arranged on the support plate 21 28 a kind of support frame 18 is formed, whereby the loosening or tearing down the respiratory mask 3 prevented by impact on the protective helmet 2 becomes.

Another major advantage is that existing protective helmets 2, which are formed with none of the connecting devices 7, 35, 51 described in this way are, by this support frame 72 for a strapless attachment of the respirator 3 can be easily retrofitted on the protective helmet 2 because of the training of the holding frame 72, these are simply attached to the supporting frame 18 of the protective helmet 2 can.

It is also possible for the force to release the protective helmet 2 from the holding frame 72 predetermined by arranging snap devices as fastening means 75 can be prevented, so that the protective helmet 2 is released from the support frame 72.

10 is an embodiment for forming the connecting devices 7, 35, 51, as shown in FIGS. 1 to 9 described above. At In this exemplary embodiment, a three-point holder of the respiratory mask 3 is used Protective helmet 2 shown, the breathing mask 3 is not shown.

The protective helmet 2 thus has the connecting devices arranged in the flank region 20 7 and the connecting device 35 arranged in the region of the forehead 36 on, wherein the individual connecting devices 7 and the further connecting device 35 are in turn formed by the coupling parts 25, 31 and 37, 38. For this purpose, the helmet-side coupling parts 25, 37, as described in the above Figures are used, again by the locking straps 26, 39 with the on their Surface rests 34 formed. In addition is now the further one Coupling part 31, 38, in particular latching clasp 32, 40, on coupling part 25, 37 arranged. This ensures that the locking clasp 32, 40 is fixed on the locking strap 26, 39 is in the end area, i.e. on the opposite side of the coupling parts 25, 37 bearing pivot axis 23, 42, an end piece 77 is arranged. By this end piece 77, it is no longer possible to the coupling part 31, 38, in particular the locking clasp 32, 40, from the coupling part 25, 37, in particular from the locking band 26, 39.

So that a connection can be made with the respiratory mask 3, have the coupling parts 31, 38 on their surface in the direction of the respiratory mask 3 arranged connection devices`, in particular snap devices 78,. On the respiratory mask 3 there is a corresponding one, which receives the snap device 78 Clasp, in particular in turn a snap device 78, arranged, so that by pressing the coupling part 31, 38 onto the face mask 3 arranged snap device 78, the respiratory mask 3 with the protective helmet 2 can be connected.

By connecting the coupling parts 31, 38, it is then possible that a Adjustment of the coupling parts 25, 31 and 37, 38 to each other by loading the breathing mask 3 is reached with pressure in the direction of the face 13 of the user becomes.

11 shows a further exemplary embodiment for the connecting devices 7, 35, 51 for connecting a breathing mask 3 to the protective helmet 2 without a strap shown without the respirator 3, in the illustrated embodiment a three-point holder of the respiratory mask 3 is shown. Of course it is possible that this embodiment also for a five-point bracket the breathing mask 3 can be used on the protective helmet 2.

The connecting devices 7, 35 are in turn each by two coupling parts 25, 31 for the connecting device 7 and arranged in the flank region 20 two coupling parts 37, 38 formed for the connecting device 35. The helmet side Coupling parts 25, 37 are now carried out by a snap band 79, 80.

The snap band 79, 80 of the connecting devices 7, 35 points in the longitudinal direction several openings 81 with a diameter 82. The lengthways Breakthroughs 81 arranged next to one another are connected to one another via recesses 83 connected. The recesses 83 have a width 84 which is opposite to that Diameter 82 of the openings 81 is smaller.

The clasp corresponding to this snap band 79 becomes, as in FIGS 9, on the breathing mask 3, in particular on the mounting frame 11 for the viewing window 10 arranged. The clasp is designed so that this in one Housing has a pin, for example in the upper area Indentation is arranged, which corresponds to the width 84 of the recess 83, whereas the pin has a diameter which corresponds to the diameter 82 of the openings 81, having. Furthermore, the pin 79, 80 is in the housing via a spring arrangement stored so that by inserting the snap band 79, 80 in the housing of the pin lowered from the snap band 79, 80, for example in the direction of the respiratory mask 3 is, so that if there is agreement when pressing the respiratory mask 3 in In the direction of the face 13, the pin engages in the first opening 81. Subsequently the user can press the button on the clasp Lower the peg until the recess 83 arranged on the peg with the Snap band 79 arranged recess 83 matches, so that a shift possible in the longitudinal direction through the recesses 83 in the next opening is.

In the different embodiments of the connecting devices 7, 35, 51 it is possible that each of the connecting devices 7, 35, 51 is different can be executed.

In the exemplary embodiments described in FIGS. 1 to 11, the arrangement or the positioning of the individual connecting devices 7, 35, 51 on the support frame 18 or on the protective helmet 2 to each other of particular importance, because of the special Arrangement a uniform pull on the respirator 3 in the direction of the face 13 is achieved via the connecting devices 7, 35, 51. For better illustration the arrangement of the connecting devices 7 according to the invention, 35, 51 in FIG. 8 this is done by two imaginary cylinders 85, 86 with a corresponding one Diameters, which are shown in dash-dotted lines. The helmet-side, the coupling parts 25 assigned to the flank regions 20 of the protective helmet 2 are tangent approximately in their connecting position on an outer surface 87 of the imaginary first Cylinder 85. The imaginary first cylinder 85 is arranged in this manner in the protective helmet 2, that this is approximately perpendicular to the two flank regions 20 of the Protective helmet 2 extends. The further coupling part arranged in the region of the forehead 36 37 of the further connecting device 35 is in the region of a longitudinal axis 88 of the imaginary first cylinder 85. With this arrangement, a Three-point connection an exact definition of the arranged in the connection position Coupling parts 25, 37 reached, so that a simple press on the respirator 3 is achieved without tilting the individual connecting devices 7, 35.

When using a five-point bracket, i.e. by arranging the additional Connection devices 51, in turn, for better illustration the position of the connecting device 51, in particular the coupling parts 52, 53, an imaginary second cylinder 86 is used. The coupling parts 52, 53 of the additional Connecting device 51 is also approximately tangent to an outer surface 89 of the second imaginary cylinder 86. The imaginary second cylinder 86 is in the same Position like the first imaginary cylinder 85 for the first and second clutch parts 25 arranged. A radial distance 90 between the first and second coupling parts 25 and the coupling part assigned to the additional connecting device 51 52, 53 is greater than a radial distance 91 between the first and second Coupling part 25 and the third coupling part 37. Due to the special arrangement is again achieved that a uniform pull on the respirator 3 in Direction of the face 13 arises and thus a light pressure on the respirator 3 without tilting the individual connecting devices 7, 35, 51 becomes.

Of course, it is possible that the coupling parts 31, 38, 54 of the breathing mask 3 and the corresponding coupling parts 25, 37, 52, 53 of the protective helmet 2 by any other form of connecting device known from the prior art 7, 35, 51 can be formed. For this it is possible, for example, that the coupling parts 31, 38, 54 of the respiratory mask 3 via a bracket with the mounting frame 11 of the viewing window 10 of the breathing mask 3 are connected. Furthermore it is possible that the mask-side coupling parts 31, 38, 54 of the connecting devices 7, 35, 51 via a connecting element, e.g. a snap or snap connection, are connected to the breathing mask 3.

It is also possible that the respiratory protection-side coupling parts 31, 38, 54 via, for example a support plate is attached to the sealing edge 12 of the breathing mask 3 could be. For this purpose, the support plate or the sealing edge 12 is formed in such a way that the resulting breakthroughs are sealed airtight. It is also possible, that the support plate is glued to the sealing edge 12, so that subsequently on the support plates, the coupling parts 31, 38, 54 can be attached.

Furthermore, it is possible that 26, 39, 55 and 56 locking rods are used instead of the locking straps can be. For this purpose, the locking rods have a corresponding diameter on the outer circumference of which the catches 34 are then arranged. This is it of course, necessary that the corresponding when using locking bars Coupling parts 31, 38, 54 on the respiratory mask 3 are designed accordingly have to be.

Furthermore, it is possible that not all connection devices are used when the holding frame 72 is used 7, 35 and 51 must be arranged, but that only in different Areas as required, the individual connecting devices 7, 35, 51 are arranged. This is advantageous because, for example, when used a protective helmet 2, the already in the flank areas 20 Has connecting devices 7, via the support frame 72 from the two-point bracket for the respiratory mask 3, a three-point bracket with the additional connecting device 35 or a five-point bracket with the additional connecting device 51 can be created.

Of course, it is possible that, as in the exemplary embodiments described above, the locking straps 26, 39, 55 and 56 on the support frame 18 of the protective helmet 2 must be arranged, but that they are attached to the respirator 3. For this purpose, it is then necessary that the corresponding locking clasps 32, 40, 57 are arranged on the support frame 18 of the protective helmet 2. Has been an advantage with such a design proved that the locking clasps 32, 40, 57 not directly be connected to the support frame 18, but that these on swivel plates are positioned, the pivot plates then connected to the support frame 18 are. This ensures that the arrangement of the swivel plates the locking clasps 32, 40, 57 are pivoted out of the interior 30 of the protective helmet shell 17 can be, so that in turn the user easy access to the individual locking clasps 32, 40, 57 obtained.

It is also possible that the helmet-side coupling parts 25, 37, 52 and 53 of the connecting devices 7, 35, 51 via stops or snap or snap connections each held in the rest position or firmly in the connection position on the protective helmet 2 or are supported on the support frame 18.

Furthermore, it is possible that the helmet-side coupling parts 25, 37, 52, 53 on the Support frame 18 are supported or stored and the protective helmet 2, in particular the Protective helmet shell 17, connected to the support frame 18 via a releasable connection is. For this purpose, it is possible that the support frame 18 between this and the Protective helmet 2 arranged inner helmet assigned, preferably connected to this is. It is also possible that the support frame 18 by one within the outer boundary 44 of the protective helmet 2 lying inner helmet is formed.

Finally, it should be mentioned that in part for a better understanding of the invention Solution of individual parts purely schematically or to scale or are disproportionately enlarged or reduced.
