BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is explained in the following by means of preferred embodiments with reference to the figures. The figures show:

[0025] FIG. 1A: A front view of an embodiment of a visor according to the invention;

[0026] FIG. 1B: A cut along the plane A-A, shown in the FIG. 1A;

[0027] FIG. 1C: A perspective view of the embodiment of FIGS. 1A and 1B.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] An embodiment of visor 1 for a ballistic protective helmet (not shown in the figures) according to the invention is shown in the FIGS. 1A, 1B and 1C, wherein the FIG. 1A presents a front view, the FIG. 1B a cut along the plane A-A shown in the FIG. 1A and the FIG. 1C a perspective view.

[0029] The visor 1 has a visor pane 2 and a splinter protective lip 3, arranged in an edge region of the visor pane 2, wherein the splinter protective lip 3 encloses an edge 4 of the visor pane 2 at least partly. The visor 1 is basically suitable for a ballistic protective helmet, which is for example worn by the policemen or special operations forces. Also conceivable is a military usage of the protective helmets, respectively the visor 1 according to the invention.

[0030] The visor 1 may be a ballistic visor, a splinter protective visor and/or an impact protective visor. Ballistic visors are preventing the field of view of a wearer from projectiles from firearms, slings, bows, etc., splinter protection visors from splinters and impact protection visors from punches, whereby e.g., this is also understood to mean, for example, the impingement of objects such as stones or glass bottles. Basically, visors may also have a combination of the mentioned properties, that is, e.g., protect from projectiles, splinters and punches or protect from splinters and punches, etc. The protective effect is achieved by the visor pane 2 in combination with the splinter protective lip 3. Basically, the visor pane 2 may be a single pane of suitable thickness or multiple layers of panes.

[0031] In the embodiment of the FIGS. 1A, 1B and 1C the visor has one single visor pane 2. As already mentioned, in other embodiments the visor pane may be a multilayer construction. Suitable materials for the visor pane 2 are for example polymethyl methacrylate (PMMA) and polycarbonate (PC). In case of a multilayer construction, the layers may be connected to each other by means of an adhesive.

[0032] A variety of materials can be used for the visor pane, like e.g., glass, ceramic and plastics like e.g., polymethylmethacrylate (PMMA) and polycarbonate (PC). Depending on the protection class, the pane may consist of only one material or a combination of the mentioned materials in which the visor pane is constructed layer by layer. The connection of the single layers usually happens (preferably) by gluing, but also mechanical connections are conceivable like e.g., by screwing or by a frame, which holds the panes together.

[0033] In the embodiment of the FIGS. 1A, 1B and 1C the visor 1 has a visor carrier 5, which is configured to connect the visor 1 with a ballistic protective helmet (not shown in the figures). In this way, the visor 1 is removably and permanently secured to the protective helmet. The visor carrier has two bearings 10a and 10b on its sides such that the visor 1 is rotatable around the axis of rotation marked with the reference sign 11.

[0034] The splinter protective lip 3 is made of polyurethane in the embodiment of the FIGS. 1A, 1B and 1C. Concretely, this is a material that is specially optimized for flame-retardant applications. Basically, also other materials are conceivable as long as they have sufficient flame retardancy, breaking resistance and solidity.

[0035] The splinter protective lip 3 is glued with the visor pane. In the embodiment of the FIGS. 1A, 1B and 1C, an adhesive 12 is used based on polyurethane. Basically, also other adhesives can be used, like e.g., an adhesive, which is cured under UV light. A prerequisite for this is that the adhesive has similar characteristics like for example flexibility, elongation at break and solidity like the splinter protective lip 3 itself.

[0036] In the embodiment of the FIGS. 1A, 1B and 1C, the splinter protective lip 3 has a thickness 6 of 2.2 mm (see FIG. 1B). It is also shown in FIG. 1B that the splinter protective lip has a U-shaped cross-section and thus covers the face side 9 of the visor pane 2 as well as its front side 7 and back side 8 at least partly. Other cross sections are conceivable. For example, the cross-section may be L-shaped such that the splinter protective lip 1 covers the face side 9 and the external side 7 or the internal side 8 of the visor pane 2.

[0037] In the embodiment of the FIGS. 1A, 1B and 1C the splinter protective lip 3 encloses the circumferential edge of the visor pane 2 together with the visor carrier 5 almost completely. Thereby, the splinter protective lip 3 encloses alone more than half of the circumferential edge, namely the sides and the bottom side, while the visor carrier encloses the top side of the visor pane (see FIG. 1A).
