Definitions
- the present invention relates to a protective helmet, in particular for Motorcyclists or the like, according to the preamble of claim 1.
- Protective helmets of the type mentioned come in many, some very different areas and are used in both In the field of occupational safety as well as in the leisure and sports sector as protective headgear.
- the essential Components of a protective helmet namely the one usually Outer shell trained outer shell and lining, independently special, complementary functions.
- the Outer shell is usually relatively rigid and serves as outer protective covering of the lining as well as possible uniform, flat initiation of impact impacts in the Lining.
- the lining itself essentially serves as a receptacle and to reduce impact energy before it hits the head of the helmet wearer reached.
- the Shell lining usually relatively flexible and elastic as well dampened
- the Outer shell and the shell lining of one Have a hard hat is for those with a hard hat achievable protective effect of the seat of the helmet crucial on the head of the helmet wearer.
- the best The protective effect is as close as possible Seat of the protective helmet or lining achieved.
- This tight fit of the protective helmet stands in a direct line with the known protective helmets Contrast to comfort.
- a tight fit is often only due to an appropriate fit tight tightening of a helmet chin strap possible. This will then in many areas a close contact between the shell lining and the head of the helmet wearer.
- the present invention is therefore based on the object based on a protective helmet with a lining create the so far incompatible Features a tight fit Seat as well as a high wearing comfort.
- the protective helmet according to the invention is lined provided, at least in some areas an evacuable one, divided into individual segments Has cushion that with elastic fillers is filled.
- the pillow When the pillow is ventilated, it is elastic Packing can be easily moved against each other and thus enable the formation of a very soft, in the form of easily changeable pillow. It is therefore special in this state of the pillow easily possible a hard hat that comes with such a Pillow lining is provided over the head to put on or remove from this. This fits the pillow or the pillow filling of the individual Skull geometry of the helmet wearer particularly good and therefore lies with the cushion surface on the entire area of the skull covered by the pillow essentially evenly.
- the protective helmet according to the invention offers more also completely new possibilities in the Hard hat assembly because of the light Adaptability of the helmet lining of several clothing sizes covered with one and the same lining can be.
- the pillow segments form individually or in a vacuum-tight combination with each other pillow units, each an evacuation device exhibit.
- beneficial Design allows an almost arbitrarily fine Division of the lining into individual evacuation zones, which then turns out to be advantageous can, if a helmet shell used as an outer shell is formed in several parts. Here you can then individual evacuation zones, the individual shell components be assigned.
- the evacuation device with one on the Outer shell arranged valve and an associated, arranged on the outside of the outer shell, provided as a suction bellows vacuum pump.
- This configuration enables the helmet wearer in a particularly advantageous manner at any time the evacuation or ventilation of the pillow to carry out itself without the necessary To have to carry facilities separately.
- Another advantageous way of training the evacuation device consists in a Provide a check valve, and the pillow unit, made as outlined above a single pillow segment or a composite of Cushion segments can be formed with a surface pressure device for venting the pillow unit to be provided by the check valve.
- This design of the evacuation device enables it for example to evacuate the pillow to use a chin strap that matches one on the outer cushion wall arranged print edition connected is, so the evacuation and the so accompanying formation of the shape stability of the pillow when putting on and tightening the chin strap he follows. This is compared to conventional Safety helmets to evacuate the pillow no additional, Measure to be carried out by the helmet wearer necessary.
- the evacuation device can also consist of at least one there are partially air-porous pillow walls, which a ventilation through the cushion wall External pressure, for example when the helmet is on is made possible. As long as the pressure remains, that is, as long as the helmet remains on the deflated condition of the pillow. After acceptance of the helmet the pillow gradually becomes again ventilated.
- the pillow Island areas or recesses preferably in the areas covering the ear cups of the helmet wearer the outer shell. This will on the one hand, particularly pressure-sensitive areas on Cut out the head of the helmet wearer. Second, remains the sound absorbing effect of the pillow Recesses or island areas without influence on the Hearing of the helmet wearer, so that this also a contribution to traffic safety is made.
- Such Bridges can be made of thermoplastic material formed pillow walls for example There are welds. Those so formed, for example Bridges make separate facilities No need to create partitions.
- a connection of the pillow segments with each other can through air-permeable intermediate areas in the webs or also through air duct or air line connections or via a central air line.
- the pillow walls can with an outer, the Helmet outer shell facing and / or an inner, the top layer facing the head of the helmet wearer be made of different materials and / or have different material surfaces can. This makes it possible to use the top layers as Train functional layers, each with special have properties corresponding to their arrangement.
- the outer cover layer can be coated with an adhesive be provided which is an undesirable
- the outer shell of the helmet slides on the outer cover layer prevented.
- the adhesive coating can even separate connection devices between the top layer and the outer shell of the helmet make redundant.
- the inner Top layer as a climate system with at least two Layers made of different materials is.
- One facing the head of the helmet wearer Outer layer can be made of an air and moisture permeable synthetic material and an in between the outer layer and the lining arranged Intermediate layer made of an absorbent material, such as a fleece or a cotton layer.
- the inner top layer interchangeably attached to the lining is particularly advantageous.
- FIG. 1 shows a protective helmet 10 which is shown with a cut outer shell 11 and placed on the head of a helmet wearer for a better explanation.
- the embodiment of the protective helmet shown here is a jet helmet for motorcyclists.
- this helmet could equally well be designed as a half-shell helmet or an integral helmet.
- Lighter embodiments, such as those used by cyclists, are also conceivable, particularly with regard to the design of the outer shell of the helmet.
- a lining 12 is provided in each case, which in this exemplary embodiment is formed overall as a coherent vacuum cushion with individual cushion segments, of which only the cushion segments 13 in side view due to the representation of the protective helmet 10 in FIG. 1 , 14, 15 and 16 are visible. Further, correspondingly arranged pillow segments are arranged on the opposite side of the head, not shown here.
- the individual pillow segments 13, 14, 15 and 16 are by means of webs 18, 19, 20, 21 in a vacuum-tight manner from one another divided and together form a pillow unit a common, a check valve 31 and one Suction bellows 32 evacuation device.
- the webs 18, 19, 20, 21 all around the pillow segments 13, 14, 15, 16 are formed. It is just as good however, it is also possible that the webs only in some areas Partitions between the individual pillow segments represent and in the remaining areas the segments are merged into one another.
- the cushion segments are arranged radially on the head of the helmet wearer and converge in an apex region 22.
- a tonsurf-shaped recess 23 is provided in the lining 12, in which air lines 24, 25, 26, 27 are arranged, which start from the crown end regions of the cushion segments 13, 14, 15 and 16 and open into a common connecting piece 28.
- a collecting line 29 runs between the two cushion segments arranged at the back of the helmet wearer, of which only one cushion segment 16 is shown in the view shown in FIG.
- check valve 31 covering the check valve 31 is provided on the outside of the helmet outer shell 11 of the suction bellows 32 with a vent 33.
- a ventilation device to ventilate the cushion segments 13, 14, 15 and 16, the check valve 31, not shown in detail here, is provided with a ventilation device, not shown.
- the webs 18, 19, 20 and 21 in are for ventilation Partial areas or completely with perforations 42 provided an air exchange between the outer Enable the environment and the head surface.
- the tonsure-shaped one also plays a key role in this Recess 23 in the crown region 22 at.
- the cushion segment 15 is provided with a further recess 34, which serves to receive an ear cup 35.
- an island region of the cushion segment 15 (not shown here in more detail) can also be provided, which, like a web, can be formed from adjacent regions of cushion walls 36, 37 (FIG. 2) and provided with perforations, but differently from this one has a flat extent that covers the auricle area.
- FIG. 2 shows a cross-sectional representation of the cushion segment 15 in a region between the webs 19 and 20.
- the structure of the lining 12 as a whole is clear from this representation.
- the lining 12 has two pillow walls, the outer pillow wall 36 and the inner pillow wall 37, which are connected by webs 19, 20 to form the pillow segments, of which the pillow segment 15 is shown here by way of example, which here are welded in regions or heat-sealed in regions the cushion walls 36 and 37 are formed together.
- the cushion segment 15 and the other cushion segments are filled with elastic fillers 38 which, when the cushion segment 15 is in the ventilated state, can be moved freely against one another, thereby creating a soft and less elastic design of the cushion segments.
- the outer Functional top layer 39 consists of a hard-wearing Material covered on the outside with a rubber adhesive coating 41 is provided and therefore for a good one Hold the lining 12 in the outer helmet shell 11 worries.
- the inner functional cover layer 40 is as one Air conditioning system with an outer synthetic layer 43 and an absorbent intermediate layer 44 made of a Fleece provided and thus ensures a pleasant Helmet wearer comfort.
- the individual cushion segments of the lining 12 in the initial state so when putting on the protective helmet 10, in a ventilated state, so that the hard hat 10 without much resistance simply on the Head of the helmet wearer can be put on.
- the cushion segments become a comfortable sitting position the lining 12 by repeatedly pressing the Suction bellows 32 vented, causing the inner Functional cover layer 40 in its contour of the skull contour of the helmet wearer fits snugly. Because of the contact areas thus formed over a large area between the liner 12 and the head of the Helmet wearer is already a relatively low pressure the lining on the head of the helmet wearer is sufficient, an exact, essentially immovable Ensure the fit of the protective helmet 10 on the head.
- the packing 38 are now close to each other on and are no longer relative to each other movable. This makes the previously soft, inelastic Training the liner 12 by a relative unyielding, elastic damping training replaced, the elastic damping properties essentially by the material properties the filler 38 are predetermined.
- the one shown here Embodiment consist of the packing 38 from styrofoam balls; but can also from other suitable, elastic plastics.
- the cushion segments can be used to remove the protective helmet 10 the lining 12 by pressing the Ventilation device are ventilated so that the soft, resilient formation of the lining 12 is restored, and the protective helmet lighter can be removed.
- the outer shell is formed by a relatively rigid outer shell.
- the outer shell can also be formed by the hard-wearing outer functional cover layer 39 in particularly light versions of the protective helmet.
