DETAILED DESCRIPTION

[0075] FIG. 1 shows an exemplary embodiment of headgear 1 which is configured in the example shown as a helmet. The helmet comprises a helmet shell 50, to the underside 9 of which an eye protection device 2 is fixed. The eye protection device 2 comprises eye protection 4 which is configured in the embodiment shown as goggles 10. The goggles 10 comprise a viewing area 5 (viewing material, such as an optically transparent material), ventilation slits 54 and a seal 52, so that ventilation is achieved despite a sealing of an internal space of the goggles 10. The goggles 10 are, for example, skiing goggles.

[0076] FIG. 2 shows another exemplary embodiment of headgear 1 which is a protective helmet, as used, for example, by police officers. An eye protection device 2 having eye protection 4 in the form of a visor 11 is fixed to the underside 9 of the helmet shell 50. Neck protection 56 is, in addition, fixed to the back of the helmet, which neck protection is fixed, for example, in a detachable manner with a fastening device, with which the eye protection 4 can also be fixed to the headgear 1.

[0077] A third example of headgear 1 is shown in FIG. 3. This headgear 1 is a helmet, to which a face shield 12 is fixed as eye protection 4 by means of the eye protection device 2. In addition to a seal 52, which seals an internal space of the face shield 12 in an airtight manner when it is worn, the face shield 12 comprises an air supply device 58 which supplies the user with fresh air. In this way, the helmet can be used as simple respiratory protection.

[0078] In addition to helmets, the eye protection device 2 can also be fixed to caps or hats, for example, by sewing it into the caps and hats.

[0079] FIG. 4 schematically shows, in a simplified manner, an exemplary first embodiment of an eye protection device 2, with which, for example, the eye protection 4 from FIGS. 1 to 3 is fixed to the headgear 1. The eye protection device 2 comprises the eye protection 4 and a fastening device 8 configured separately to the eye protection 4. The eye protection 4 comprises the viewing area 5 and a frame 6 which is firmly connected to the eye protection 4. It is not necessary for the frame 4 to completely surround an outer edge of the viewing area 5, as is occasionally the case with goggles. Instead, the viewing area 5 is largely freestanding in the exemplary embodiment shown. The frame 6 comprises a contact body 20 projecting horizontally from the viewing area 5, which contact body has a first, horizontally extending contact area 21. According to other embodiments, the contact surface 21 can also be oblique. At the lateral ends of the contact body 20, two circular portions are configured, into which a first frame magnet 22 and a second frame magnet 23 are integrated centrally. A part of the frame 6 is configured as two trapeze-shaped protrusions 24 vertically offset above the contact body 20.

[0080] The fastening device 8 is configured to be fixed to the headgear 1 and provides a fixing portion 36 for this purpose. In the embodiment shown, the fixing portion 36 is configured as three holding surfaces 38 which protrude vertically upward from a rail 30 of the fastening device 8. The fastening device 8 is fixed to a helmet by means of the holding surfaces 38 and the rail 30, for example, in such a way that an upper side of the rail 30 lies in contact with a lower edge of the helmet shell 50 and the holding surfaces 38 engage in an inside of the helmet. In this state, the fastening device 8 is, for example, screwed on, glued on, sewn on, clamped or otherwise fixed to the helmet. For clamping purposes, the rail 30 can, for example, have an elastic configuration so that it presses with the holding surfaces 38 against the inside of the helmet. In order to follow the circumference of the underside of the headgear 1, the rail 30 has in addition a curved configuration.

[0081] A first holding magnet 32 and a second holding magnet 33 are integrated into the rail 30. Since the holding magnets 32, 33 are not visible in the selected view, the position of the holding magnets 32, 33 is merely indicated as a dashed line. In addition, the rail 30 comprises two recesses 34 which are introduced into the upper side of the rail 30 and extend approximately up to half the height of the rail 30. The recesses 34 are configured in a form fitted manner or with a complementary shape to the protrusions 24. In the separated state of the eye protection device 2 shown in FIG. 4, the frame 6 does not lie in contact with the fastening device 8.

[0082] FIG. 5 shows a first semi-fixed state of the eye protection device 2 from FIG. 4. In this first semi-fixed state, the portion of the first contact surface 21, in which the second frame magnet 23 is integrated, lies in contact with a second contact surface 31 of the rail 30 from below, so that the second frame magnet 23 is arranged below the second holding magnet 33 and these magnetically attract one another or respectively are magnetically coupled with one another. By way of contrast, the first frame magnet 22 is not magnetically coupled with the first holding magnet 32.

[0083] As an alternative to the state shown in FIG. 5, in the first semi-fixed state, the first frame magnet 22 can also magnetically couple with the first holding magnet 32, while the second frame magnet 23 does not magnetically couple with the second holding magnet 33. In any case, the eye protection 4 can be pivoted, in the first semi-fixed state, about a vertical axis 60. This makes it possible to quickly and easily flip up the viewing area 5 or to flip it down, depending on whether the eye protection 4 is needed.

[0084] In the completely fixed state shown in FIG. 6, both the first pair of magnets, that is to say the first frame magnet 22 and the first holding magnet 32, as well as the second pair of magnets, that is to say the second frame magnet 23 and the second holding magnet 33, each magnetically couple with one another. At the same time, the protrusions 24 are arranged in the recesses 34 which are form fitted or complementary shaped. In this way, the protrusions 24 secure the eye protection 4 on the fastening device 8. In this completely fixed state, the eye protection 4 is held securely on the fastening device 8 and, therefore, on the headgear 1.

[0085] FIGS. 7 to 9 show, in a schematically simplified and perspective manner, a second embodiment of the eye protection device 2. As depicted in FIG. 7, as well as the frame magnets 22, 23, the frame 6 in addition comprises a centrally arranged first prefixing magnet 29. The frame magnets 22, 23 are, in addition, integrated into separate portions of the contact body 20, which comprise separate first contact surfaces 21 and, in each case, a latch element 26 protruding vertically upward. A second prefixing magnet 39 is centrally integrated into the rail 30 of the fastening device 8, which is merely indicated as dashed lines on the basis of the representation. To the side of the second prefixing magnet 39, two walls project downward from the rail 30. The walls enclose a gap which is formed in a form fitted manner or in a complementary shape to a portion of the frame 6, into which the first prefixing magnet 29 is integrated. The second embodiment does not have protrusions 24 or recesses 34 similarly to the first embodiment.

[0086] FIG. 8 shows the second embodiment of the eye protection device 2 in a second prefixed state. In this second prefixed state, the first prefixing magnet 29 is prefixed to the second prefixing magnet 39 in such a way that they magnetically attract one another and the eye protection 4 is held on the fastening device 8. The downwardly protruding gap on the rail 30 prevents lateral displacement of the frame 6 with respect to the rail 30. However, a latching mechanism, comprising holding teeth 40 and assigned recesses 42 (only one of which is in each case provided with a reference numeral for reasons of clarity), prevents the frame 6 from being transferred from the depicted tilted state into the vertical state depicted in FIG. 9 by the pull of the prefixing magnets 29, 39. In the depicted second semi-fixed state of the eye protection device 2, the frame magnets 22, 23 consequently do not magnetically couple with the holding magnets 32, 33. Due to the latching mechanism, the eye protection 4 can be tilted about a horizontal swiveling axis 70. This makes it possible to either flip the viewing area 5 either completely upward, so that the user has a clear view, or to flip the viewing area 5 downward and to transfer it into the completely fixed state of the eye protection device 2 shown in FIG. 9, so that the viewing area 5 is positioned in front of the user's eyes.

[0087] As depicted in FIG. 9, in the completely fixed state, not only do the prefixing magnets 29, 39 magnetically couple with one another, but also the frame magnets 22, 23 couple with the corresponding holding magnets 32, 33. The latch elements 26, which lie in contact with a rear edge of the rail 30, prevent the eye protection 4 from being extracted horizontally from the fastening device 8 and therefore secure the eye protection 4 on the headgear 1.

[0088] The first prefixing magnet 29 can, in addition, be utilized in order to fasten the eye protection 4 to a retainer when the eye protection 4 is not needed. The retainer 4 is, for example, fastened to a garment, by way of example a vest of the user, and comprises, for example, a retaining magnet. Alternatively, in the first embodiment or the second embodiment of the eye protection device 2, a separate additional magnet, which is not shown, with which the frame 6 is magnetically fixed to the retainer, can also be provided.

[0089] While there has been shown and described what is considered to be embodiments of the invention, it will, of course, be understood that various modifications and changes in form or detail could readily be made without departing from the spirit of the invention. It is therefore intended that the invention be not limited to the exact forms described and illustrated, but should be constructed to cover all modifications that may fall within the scope of the appended claims.
