DETAILED DESCRIPTION

[0038] FIGS. 1 and 2 show a skull mounting system 1 for headgear 2 depicted in FIG. 7, preferably a respirator hood 3 (FIG. 7). It has a headband 4 from components with lower elasticity, consisting of a front headband 5 and a rear headband 6, the front headband 5 extending around at least the front of the head 7 of a wearer and the rear headband 6 being situated on the back of the head 7 of the wearer. At least one upper headband 8 is provided, which extends over the top of the head 7 of the wearer and has higher elasticity. The upper headband 8 is rubber-elastic in the depicted embodiment example.

[0039] Several upper headband sections 9, specifically three upper headband sections 9 are shown, which are guided over the top of the head 7 of the wearer. The lengths of the upper headband sections 9 intersect once and form a coherent one-piece upper headband 8.

[0040] It is also shown that the rear headband 6 is connected by means of swivel joints 15 to the front headband 5. The swivel joints 15 can be firmly locked in several rotational positions. The rear headband 6 has a length adjustment 16, by means of which the length of the rear headband 6 can be adjusted.

[0041] The front headband 5 has end section 17 that extend in the direction of the back of the head after a connection point 18 at which the front headband 5 and the rear headband 6 are connected to each other.

[0042] It is also shown that the upper headband 8 is guided by connection slits 19 in the front headband 5. The ends of the upper headbands 20 are loosely clamped into the connection slits 19 on the front headband 5, so that the length of the upper headband 8 can be adjusted by loosening the clamping.

[0043] A front headband 5 is shown in FIG. 3 in the stretched state, wherein FIGS. 4 and 5 show sectional views drawn in this figure.

[0044] It is also shown in FIG. 3 that the inside of the front headband 5 is at least partially backset in an area 14 arranged on the temples 26 of the wearer when worn. Due to this measure, the back offset area 14 does not come in contact with the head 7 of the wearer when the skull mounting system 1 is worn. In addition, the front headband 5 has lower flexibility in this back offset area 14 than in the adjacent areas. As is apparent from FIG. 1, this is achieved in that recesses 13 that are incorporated in other areas of the front headband 5 are not incorporated in this area 14.

[0045] The upper headband 8 is configured so that it is guided by front connection slits 21 in the front headband 5 in the area arranged on the temples 26 of the wearer when worn. The upper headband 8 is also guided by rear connection slits 22 in the front headband 5. The rear connection slits 22 are situated in the end sections 17 of the front headband 5, wherein the end sections 17 extend in the direction of the back of the head after the connection point 18 depicted in FIG. 1, at which the front headband 5 and the rear headband 6 are connected to each other.

[0046] The front headband 5 is configured so that it has front connection devices 23 for connection to headgear 2, which extend upward in the area arranged on the temples 26 of the wearer when worn. Two rear connection devices 24 for connection to the headgear 2 are also shown, which are found in the area of the end section 17, in which case the end sections extend in the direction of the back of the head after the connection point 18 depicted in FIG. 1, at which the front headband 5 and the rear headband 6 are connected to each other.

[0047] FIG. 3 also shows that the front headband 5 has rear connection devices for connection to headgear 2, which are formed by longitudinal slits 25, into which a fastening part (not shown) of headgear 2 can engage. The fastening part here is arranged movable along the longitudinal slit 25.

[0048] As is apparent from FIG. 4, the front headband 5 has a convex arch 10 at least in areas extending along the length of the front headband 5 in an area that can directly or indirectly come in contact with the forehead of the wearer when worn.

[0049] It is apparent from FIG. 5 that the unloaded front headband 5 has a concave arch 12 at least in areas extending along the length of the front headband 5 in an area that can directly or indirectly come in contact with the lateral sides 11 of the head 7 of the wearer depicted in FIG. 6 when worn.

[0050] The front headband 5 here is configured so that the convex arch 10 and/or the concave arch 12 is deformed relative to arch 10, 12 when forces are applied in the longitudinal direction on the front headband 5. In order to facilitate this, the headband 4 has the recesses 13 in the longitudinal direction depicted in FIGS. 1, 4 and 5, which are suitable for increasing the flexibility of headband 4 in the vertical direction.

[0051] FIG. 6 shows the head 7 of a wearer with temples 26 and the lateral sides of the wearer's head 11.

[0052] FIG. 7 shows a respirator hood 3, which is fastened to the head 7 of a wearer by the skull mounting system 1 described above. For this purpose, the skull mounting system 1 is connected to the respirator hood 3 by means of the front connection devices 23 and the rear connection devices 24. The rear connection devices 24 are formed in the area of the back of the head by slits into which a counter connection device (not shown) on the respirator hood 3 engages and is mounted movable in the longitudinal direction.

[0053] It is further shown that a corresponding respirator hood 3 preferably has a visor 27, the visor 27 being clear and transparent in the visual field. The visor 27 is connected to the skull mounting system 1 by means of two additional swivel joints 30, directly or indirectly, and can be tilted upward by means of the additional swivel joints 30. Here, it is advantageous if the transparent part of the visor 27 can be easily changed in order to replace it with a new part when it becomes soiled. The transparent part is made from a clear, transparent plastic part.

[0054] The respirator hood 3 also has a hood cover 28, which delimits the respirator hood 3 at least in areas in the form of an enclosure, so that an overpressure develops in the respirator hood 3, preventing particles or pollutants from penetrating into the internal area of the respirator hood 3 from the outside. For this purpose, the respirator hood 3 is supplied compressed air by means of a compressed air connection 29.

[0055] It should be understood that the present invention has a plurality of different features which may be utilized separately or in various combinations. It is also contemplated that the various features of the invention may be utilized with known features from the prior art. Although specific combination of features have been described herein, it is contemplated that other combinations of features will be apparent to those skilled in the art and will be formed.

[0056] Furthermore, although certain applications are described herein, those of ordinary skill in the art will appreciate other applications for the present invention.

[0057] In view of the foregoing, it should be understood that variations and modifications within the spirit and scope of the invention might occur to those skilled in the art to which the invention pertains. Accordingly, all expedient modifications readily attainable by one versed in the art from the disclosure set forth herein that are within the scope and spirit of the present invention are to be included as further embodiments of the present invention. The scope of the present invention is accordingly defined as set forth in the appended claims.
