DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0039] Initially with reference to FIGS. 1, 2, a forestry worker safety helmet comprises a dish-like helmet shell 1 and a visor arrangement 2 which is arranged on the helmet shell 1.

[0040] The helmet shell 1 is formed rigidly and preferably from plastics material. It serves to cover the head of a helmet wearer.

[0041] There is arranged on the helmet shell 1 in each case a carrier arm 3 which can be moved, in particular pivoted and/or displaced, with respect to the helmet shell 1 and which carries the visor arrangement 2. The visor arrangement 2 can in turn advantageously be pivoted with respect to the carrier arms 3. It can be moved in its entirety between a lower protective position shown in FIG. 1 and an upper parking position (not shown). In use, the visor arrangement 2 which is located in the protective position is protectively in front of the face of the helmet wearer and is transparent, whilst it is then moved upward away from the face of the helmet wearer in the parking position thereof.

[0042] The visor arrangement 2 comprises a protective panel element 4 which is constructed in this instance as a full-face protective panel element and is formed from transparent, impact-resistant plastics material. The protective panel element 4 has a closed protective panel 5 and two bearing means 6 which are arranged laterally at the top. The protective panel 5 provides a viewing region.

[0043] Furthermore, the protective panel element 4 has a transverse web 7 which adjoins an upper edge 8 of the protective panel 5 and which protrudes at that location counter to a viewing direction 9 of the visor arrangement 2, that is to say, toward the rear or toward the inner side. The transverse web 7 extends substantially between the bearing means 6.

[0044] The bearing means 6 are constructed as bearing openings which are substantially circular and closed at the peripheral side.

[0045] In the assembled state of the protective panel element 4, there extends through each bearing means 6 a bearing member arrangement 10 which also extends through a corresponding bearing hole 11, which is closed at the peripheral side, in the corresponding carrier arm 3 and which defines a pivot axis. Via the bearing member arrangements 10, the protective panel element 4 is connected to the carrier arms 3 and thus to the helmet shell 1 in an articulated manner.

[0046] Furthermore, the visor arrangement 2 comprises an additional protective grid element 12 which in the assembled state is arranged at the outer side with respect to the protective panel element 4. The additional protective grid element 12 is constructed as a full-face additional protective grid element. It has a grid region 13 and a frame portion 14 which completely extends around/surrounds the grid region 13. The grid region 13 is formed by a grid (network). Meshes formed by the grid region 13 advantageously have a mesh width which is between 10 and 50, in particular 15 and 40, openings/cm.sup.2. A light transmittance is preferably between 50 and 90%, more preferably between 55 and 80%. The grid region 13 provides a viewing region.

[0047] In order to locally secure the additional protective grid element 12 to the protective panel element 4, the additional protective grid element 12 has a securing arrangement which will be explained in greater detail below, in particular with reference to FIGS. 3, 4 and 6.

[0048] As particularly FIGS. 3, 4 illustrate, the securing arrangement comprises two magnet securing devices 15 which are each arranged laterally with respect to the grid region 13.

[0049] Each magnet securing device 15 has two magnetic elements 16 which are arranged laterally on the frame portion 14 and which are spaced apart from each other along the frame portion 14. Advantageously, the magnetic elements 16 are embedded in the frame portion 14. They are in this instance arranged at the carrier side or at the inner side on the frame portion 14 and are preferably free at the inner side.

[0050] Adjacent to the magnetic elements 16 of each magnet securing device 15, a folding arrangement 17 of the magnet securing device 15 adjoins the frame portion 14 laterally opposite the grid region 13. Each folding arrangement 17 has a first film hinge 18 which adjoins the frame portion 14, a spacer web 19 which adjoins the first film hinge 18, a second film hinge 20 which adjoins the spacer web 19 and a retention portion 21 which adjoins the second film hinge 20.

[0051] The spacer web 19 and the retention portion 21 of each folding arrangement 17 are integrally connected to each other. They are integrally connected to the frame portion 14.

[0052] The first film hinges 18 extend partially along the frame portion 14. The film hinges 18, 20 of each folding arrangement 17 extend parallel with each other. Advantageously, with each film hinge 18, 20 there is a reduced thickness and/or material weakening in order to form in each case a corresponding pivot axis.

[0053] Each spacer web 19 is rectangular and can be pivoted about the associated first film hinge 18 with respect to an adjacent region of the frame portion 14. Each spacer web 19 has a width which substantially corresponds to an edge-side thickness of a side region of the protective panel element 4.

[0054] Each retention portion 21 is rectangular and can be pivoted via the associated second film hinge 20 with respect to the adjacent spacer web 19.

[0055] Each retention portion 21 carries two magnetic counter-elements 22 which are arranged spaced apart from each other along the retention portion 21. The spacing of the magnetic counter-elements 22 of a retention member 21 corresponds to the spacing of the magnetic elements 16 of a magnet securing device 15.

[0056] Each retention portion 21 can be pivoted between a retention position (FIG. 4) and an assembly/disassembly position (FIG. 3, left) about the adjacent first film hinge 18 and/or the second film hinge 20.

[0057] In the retention position in the assembled state of the additional protective grid element 12 between each retention portion 21 and a corresponding adjacent region of the frame portion 14, the protective panel element 4 is partially enclosed at that location. Each retention portion 21 then extends substantially parallel with an adjacent region of the frame portion 14 and the respective magnetic elements 16 are in magnetic connection with the then-opposing magnetic counter-elements 22 so that the respective retention portion 21 is virtually retained at the rear side on the protective panel element 4. The magnetic elements 16 and the magnetic counter-elements 22 are to this end polarized in such a manner that they then attract and a magnetic connection is produced. The protective panel element 4 is arranged between the spacer webs 19. The spacer webs 19 extend at that location in an adjacent manner along the protective panel element 4.

[0058] In the assembly/disassembly position which also forms a release position, the respective retention portion 21 is raised from the protective panel element 4 and the magnetic connection between the magnetic counter-elements 22 and the associated magnetic elements 16 is released. The additional protective grid element 12 can thus be lifted from the protective panel element 4.

[0059] Furthermore, the securing arrangement has a surrounding receiving member 23 (FIG. 6) which is constructed in an upper edge region 24 of the frame portion 14. The surrounding receiving member 23 is open in the viewing direction 9 of the visor arrangement 2, that is to say, toward the front or outer side. It has a locking opening 25 at the upper side.

[0060] In the assembled state of the additional protective grid element 12, the transverse web 7 engages, in particular in a positive-locking manner, in the surrounding receiving member 23, wherein a locking projection 26 which is arranged at the top on the transverse web 7 engages in a locking manner from below in the locking opening 25. The locking projection 26 has an inclined introduction member 27 which rises from a free rear edge 28 of the transverse web 7 with a retention shoulder 29 being formed. The inclined introduction member 27 facilitates introduction of the transverse web 7 into the surrounding receiving member 23. The retention shoulder 29 prevents in the engaged state of the locking projection 26 in the locking opening 25 an undesirable release of the locking connection. It then faces in the engaged state a wall of the frame portion 14 which delimits the locking opening 25. Via the locking opening 25, the locking connection can be released again.

[0061] A second embodiment of the magnet securing devices will be described below with reference to FIG. 5, wherein reference will also be made to the previous description.

[0062] In contrast to the above embodiment, adjacent to the magnetic elements 16 of each magnet securing device 15, a retention portion 30 protrudes from the frame portion 14 counter to the viewing direction 9, that is to say, toward the rear or toward the inner side. There is guided, in particular in a displaceable manner, by each retention portion 30 a displacement element 31 which carries the two magnetic counter-elements 22.

[0063] In the retention position, the respective displacement element 31 engages behind the protective panel element 4 and the magnetic counter-elements 22 are in magnetic connection with the magnetic elements 16 which are then arranged in an adjacent manner.

[0064] In the assembly/disassembly position, the respective displacement element 31 is retracted and enables the arrangement of the additional protective grid element 12 on the protective panel element 4 or corresponding removal.

[0065] While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
