Description
[0001] The invention relates to a safety helmet according to the
generic term of Patent claim 1.
[0002] A safety helmet of the aforementioned type, which is
intended for military or police use in particular, is generally
known in such a way that no special evidence deriving from
publications regarding this is required. Such a safety helmet
consists of a helmet shell that fits a human head and reaches up to
his/her forehead area and a moveable, transparent visor mounted on
the helmet shell, wherein an adapter device is arranged on the
helmet shell at the forehead area for attaching helmet attachments,
such as a night-vision device. In the case of this type of safety
helmet, the visor is typically attached to the safety helmet via
swivel joints on both sides, whereby, for this purpose, passage
openings that impair the safety-related or (here and hereinafter
also mentioned:) `ballistic` characteristics of the safety helmet
must be provided on the helmet shell.
[0003] The object of the invention is to improve a safety helmet of
the aforementioned type. In particular, a safety helmet is to be
created that exhibits good wear comfort and good ballistic
properties despite the use of a heavy, bullet-resistant visor.
[0004] The task is achieved by means of a safety helmet of the
aforementioned type via features listed in the characterizing
portion of Patent claim 1.
[0005] According to the invention, it is provided that a rail
leading in the direction of the back of the head and designed for
bearing and guiding the visor is arranged on the adapter
device.
[0006] In other words, the solution according to the invention is
thereby characterized by the fact that the adapter device existing
in such safety helmets, actually intended for the attaching
attachments, such as night-vision devices, is now provided or used
for the attachment of a rail, wherein this rail extends outside of
the safety helmet over the head and is designed as a guide rail for
the visor, i.e., the visor, which may be heavy and/or
bullet-resistant where applicable, can be pushed backwards along
the rail if necessary, ensuring a good balancing of the safety
helmet.
[0007] In addition, the solution according to the invention brings
the advantage that adapters attached to the side of the safety
helmet for attaching further helmet attachments are not covered by
the visor and can therefore be used well, which is not guaranteed
in the case of known solutions where the visor is attached to the
side of the safety helmet via swivel joints.
[0008] Other favourable further embodiments of the safety helmet
according to the invention result from the dependent patent claims.
For the sake of completeness, reference is made to the further
documents DE 197 21 146 C2 and U.S. Pat. No. 7,540,033 B2.
[0009] The safety helmet according to the invention including its
favourable further embodiments according to the dependent patent
claims is explained in more detail below on the basis of the
graphic illustration of a preferred exemplary embodiment.
[0010] The figures show:
[0011] FIG. 1 in a lateral view from the left, the safety helmet
according to the invention with the visor folded down (closed
state);
[0012] FIG. 2 perspectively, the safety helmet in accordance with
FIG. 1;
[0013] FIG. 3 in a lateral view from the left, the safety helmet
according to the invention with the visor half folded up;
[0014] FIG. 4 perspectively, the safety helmet in accordance with
FIG. 3;
[0015] FIG. 5 in a lateral view from the left, the safety helmet
according to the invention with the visor fully folded up (open
state);
[0016] FIG. 6 perspectively the safety helmet in accordance with
FIG. 5;
[0017] FIG. 7 in a lateral view from the right, the safety helmet
according to the invention only with rail, but without a visor;
and
[0018] FIG. 8 in a front view, the safety helmet according to the
invention with the visor folded down (closed state).
[0019] The safety helmet shown in the figures initially consists,
in a known manner, of a helmet shell 1 that fits a human head and
reaches up to his/her forehead area and a moveable, transparent
visor 2 mounted on the helmet shell 1, wherein an adapter device 3
is arranged on the helmet shell 1 at the forehead area for
attaching helmet attachments (such as a night vision devices or the
like).
[0020] In the exemplary embodiment shown, either the helmet shell 1
and/or the visor 2 is bullet-resistant, i.e., this safety helmet is
intended for military or police use.
[0021] It is essential for the safety helmet according to the
invention that a rail 4 leading in the direction of the back of the
head for the bearing and guidance of the visor 2 is arranged on the
adapter device 3.
[0022] Thanks to the rail 4 according to the invention, it is now
possible, as is evident from FIG. 5 in particular, to position the
visor 2, which is quite heavy in the case of bullet-resistant
designs, practically on and no longer only in front of the safety
helmet, as is the case with ordinary folding visors. It is
essential that a bearing point or a bearing area of the folded-up
visor 2 is located in the area of the highest point of the helmet
shell 1. Since the safety helmet is therefore mounted on the head
of a user in a significantly better manner, this particularly also
increases--apart from the improved wear comfort--safety of course
when using the helmet.
[0023] Again, in other words, the visor 2 is arranged in a closed
state in front of a face area of a helmet user and, in an open
state, above the face side half of the helmet shell 1.
[0024] If one looks at the safety helmet according to the invention
a little more precisely, it is initially provided, in a manner
known per se, that the adapter device 3 has an interface 5 for
attaching the helmet attachments. Being particularly preferred, it
is also provided that the rail 4 is connected to the helmet shell 1
via this interface 5.
[0025] Furthermore, being particularly preferred, it is provided
that an auxiliary interface 6 corresponding to the interface 5 is
provided on the rail 4 for the attachment of the helmet components
on the forehead area side in accessible manner, i.e., thanks to
this requirement, it is ensured that helmet components, such as a
night-vision device, can be attached to the safety helmet despite
the mounted rail 4.
[0026] Furthermore, it is preferably provided that the rail 4 is
additionally attached to a brim 1.1 of the helmet shell 1 attached
to the forehead area. More precisely, being particularly preferred,
it is provided that the rail 4 is attached to the brim 1.1 of the
helmet shell 1 using a band 9. Thereby (not shown separately),
preferably, a fastening element matching the brim 1.1. of the
helmet shell 1, in particular, a hook element, is provided at the
rail-facing end of the band 9.
[0027] Furthermore, being particularly preferred, the visor 2 is
attached to a frame part 7 at its face-side end or upper brim,
wherein, in addition, a guide device 8 interacting with the rail 4
is preferably provided on the frame part 7.
[0028] This guide device 8 is (see, for example, FIG. 4) preferably
composed of two guide sections 8.2 extending parallel to on
another, accommodating the rail 4 between them.
[0029] Furthermore, being particularly preferred, it is provided
that the rail 4 comprises guide grooves pointing outwards on both
sides 4.1 and the guide device 8, in particular, the guide sections
8.2, comprises inward-facing guide elements 8.1 that fit into the
guide grooves 4.1.
[0030] Furthermore, being particularly preferred, it is provided
(see, for example, FIG. 7) that the guide groove 4.1 beginning in
the forehead area extends at least to the middle of the helmet
shell 1 (preferably even slightly beyond).
[0031] Furthermore, two preferably cone-shaped guide elements 8.1
are provided for each guide groove 4.1. Thereby, with the visor 2
folded down, preferably the one guide element 8.1 is arranged in a
first guide groove section 4.1.1 and the other guide element 8.1 is
arranged in a second guide groove section 4.1.2, wherein, in
addition, as can be seen from FIG. 7 in particular, the two guide
groove sections 4.1.1, 4.1.2 are at an angle to each other. These
requirements lead to the fact that the visor 2 is first moved
forward when folded up and only then upwards (see, in particular,
FIGS. 1, 3 and 5 or 2, 4 and 6).
[0032] In order to be able to move the visor 2 on the safety helmet
as far back as possible, as explained previously, it is also
preferably provided that the guide groove 4.1 has a length that is
at least three times as long as a distance between the two guide
elements 8.1.
[0033] In order to achieve a high tilting stability, it is also
preferably provided, as shown in the figures, that the rail is
designed as a double rail consisting of two interconnected single
rails, wherein, in addition (and this also applies to constructions
without double rail), it is ultimately preferably provided that the
rail 4 is wider than the adapter device 3 (wider refers here to a
horizontal extension direction when using the safety helmet).
