Abstract

Protective headband comprises several shock-resistant protective plates (2) arranged next to each other. Preferred Features: The protective plates run in the peripheral direction (10) of the headband and are hinged together. The protective plates are made from hard impact-resistant plastic. The headband has a cushioned layer (4) on its inner side. A textile layer (5) is formed on the outer side of the headband.

Description

I. Field of application

For winter sports, such as alpine skiing, ice skating, especially speed skating, Sledding, the athletes often protect themselves by means of headgear, such as Caps and headbands, against the cold.

II. Technical background

Especially in alpine skiing, however, is increasingly the sports doctors Wearing a head protection required to avoid head injuries during falls or at least reduce, since the late effects of such head injuries are often irreparable.

For this reason, children who are less prudent Guiding presumed helmets are widespread, the adults are afraid of wearing a helmet for several reasons: high purchase price, large transport volume as well as optical conspicuity, which still today equated with a particularly good and fast skier, which at however, many potential users are not.

III. Presentation of the invention a) Technical task

It is therefore the object of the invention to provide a head protection for winter sports create, which occupies only a small volume, especially in the transport state, is inexpensive and optically as little as possible from usual, exclusively warming, headgear is different, with the heat function in addition should be present.

b) Solution of the task

This object is solved by the features of claim 1. Advantageous embodiments emerge from the dependent claims.

The basic idea of the protective headband is to beat the head in case of a fall, etc. to be protected by hard, impact-resistant elements, e.g. out Plastic, preferably padded in the range of a conventional headband on Abut the user's head.

In the fall of a skier this usually beats with the side of the head or the back of the head on the often hard, icy ground or even one Stone or another obstacle, so an area where high Probability the protection headband is located.

Due to the impact-resistant protective elements is usually very punctual On impact on the one hand by the protective elements distributed over a larger area and thus reduce the force acting on the head per unit area, In addition, especially by the padding of the protective elements against the Head cushioned and last but not least in case of damage, especially by penetration sharp points or edges, initially damaged the protective element, and only after its penetration the user's head.

In addition, the manufacture of the protective headband by the manufacture of many, preferably identically shaped, smaller, preferably one-piece, elements Plastic relatively inexpensive, especially when connecting the elements with each other either simple, direct snap-in connections or to grant the necessary appearance and the thermal protection function usual textile material is used.

Impact-resistant protective elements, especially in the form of panels, will cause injury on the head in a collision against these protective elements instead of directly against the Head avoided or at least alleviated, as these impact resistant protective elements on the one hand by distribution over a large contact area between the protective element and head reduce the surface pressure and on the other hand by their own deformation Absorb energy, in extreme cases by destruction or damage the protective elements.

Due to the desired shape of a protective headband are suitable in the circumferential direction lined up protective plates as protective elements, especially when they are hinged together so that the headband for the Transport flat two or more layers can be merged and thus one low transport volume occupies. Other forms of protective elements e.g. a circulating in the direction of rotation of the headband spiral element or a plurality of annular protective elements are conceivable.

Also, the juxtaposed protective plates do not have each rectangular but can partially overlap in the circumferential direction, so for example C-shaped, trapezoidal or otherwise interlocking be educated. For reasons of weight, the protective elements are preferably made made of plastic, according to their purpose of hard, impact resistant Plastic, for example a fiber-reinforced plastic, in particular a Duroplast to be very common in winter sports Temperatures do not let the material become too brittle.

For reasons of comfort and power distribution in the event of impact the hard protective elements on the inside have a soft padded support usually in the form of a cushion layer. This can be continuous or on everyone Protection plate are applied individually.

By an outer circumferential, preferably continuous, textile layer over All protective elements on the one hand, the visual impression of a conventional Headband made of pure textile material, and thus reservations Dismantled against wearing such a protective headband.

A continuous layer over all protective elements, whether outer layer or Inner layer, however, on the other hand, the purpose of the articulated connection serve, so that the individual protective elements do not articulate directly with each other need to be connected via specially trained joints or the like, but just indirectly by attaching to the continuous interior or Outer layer.

Whether this continuous, the fixation of the protective elements serving, indoor or Outer layer is stretchable or just not stretchable, depends primarily on the Design of the headband from, yes a size adjustment to different Must allow head circumferences:

Is the headband as a finite strip with fasteners for closing formed into a ring, the connecting element can be changed in length be formed, for example as Velcro, so that in the course of continuous layer whose extensibility is not necessary. The connecting elements are preferably at a little impact vulnerable place the head circumference used, although in the region of the connecting element an attempt is made to avoid a gap between two protective elements.

Where this position is depends on the type of sport: normal skiers in the case of a fall often on the back of the head, rarely with the Bouncing forehead on the ground is a risk of forehead injury in ski racers much higher.

The closure should not be in the side areas of the head circumference which are most easily damaged by shock and also be taken most often.

Is the headband, however, as an endless ring-shaped headband without opening designed in one place, a stretchability of the continuous layer is necessary as a size compensation.

Then it is accepted that at an elongation of the continuous Layer the individual protection elements go to each other at a greater distance. However, if they overlap enough in the unstretched state, There must therefore be no gap between the individual protective elements.

The advantage of the connection of the individual protective plates by a continuous e.g. textile, at least flexible, outer or inner layer also consists in that with appropriate design of the protective plates, the headband between each two consecutive plates at any point on the headband, also in different places and thus several times, kinked and a flat Transport state can be merged, so that optionally one elongated but thin, since only two-ply package arises or a shorter, something thicker, e.g. four-ply package.

If the continuous layer is an inner layer, which at the same time the upholstery and heat retention at the user are the outer sides of the protective plates visible, noticeable. In order nevertheless to produce a textile-like impression usual there, can be provided on the outside of a textile flocking of the individual protective plates become.

Depending on the size and shape of the protective elements, in particular protective plates, These can either be flat or - at a certain size - arched in Adapted to the head shape, in particular on the inside.

In the sense of a cost-effective production one will endeavor as little as possible To require differently shaped protective elements, ie in particular only one or two types of protective elements, for example two in supervision on the main plane of the protective elements alike, in terms of curvature However, different degrees curved protective elements, the corresponding the curvature of the head are used, so on the side areas the Elements without or with little curvature and in the forehead and occipital areas the elements with greater curvature.

As a headband for the secure fit not above the ears but preferably over the top of the ears should be there due the hard material of the protective plates in each case inwardly and downwardly open To provide recesses for accommodating the upper ear part, wherein for the warming cover of the lower ear part earflaps or the like already may be provided on or in the protective headband.

Another possibility is to use either special, namely extended down to use ear protection plates or such ear protection plates as additional plates at the corresponding point of the headband to attach the lower edge of the local protection plate.

If the connection of the individual protective plates with each other via a continuous flexible layer takes place, such an additional plate to the corresponding attached down at this point elongated flexible layer, be attached for example by means of Velcro. If the protective plates with each other directly articulated to each other, for example, by each other latchable hinge elements or a connecting both, transverse to the direction of rotation can be inserted in a similar manner too the lower additional elements attached to the corresponding element of the headband become.

• einen Kinnschutzbügel, der im unteren Bereich mit seinen Enden an den Backenschutzplatten befestigt ist und/oder
• eine Schutzbrille, vorzugsweise in Form eines flexiblen, im Ausgangszustand ebenen, folienartigen Materials, welches an entsprechenden Befestigungselementen nahe der Unterkante des Schutz-Stirnbandes und/oder am Kinnschutzbügel befestigt werden kann, im abgenommenen Zustand aufgrund seiner ebenen Erstreckung jedoch leicht transportiert werden kann.

This makes it possible, depending on weather conditions, the current risk situation or other factors to supplement the simple headband, and to arrange, for example, on the downwardly projecting ear protection flaps out more protective elements, for example

• a chin guard, which is attached at the bottom of its ends to the shoe protection plates and / or
• a goggles, preferably in the form of a flexible, flat in the initial state, sheet-like material which can be attached to corresponding fasteners near the lower edge of the protective headband and / or on the chin guard, however, can be easily transported in the removed state due to its planar extent.

Another addition possibility are supplementary elements for closing or partially closing the upper opening of the headband, so the top of the head:

For this purpose, upper supplementary plates can be retrofitted to, for example the top edges of the panels of the protective headband, turn either directly or indirectly via the continuous flexible base course. In this Case, these additional plates must be transported separately and kept.

A better option seems therefore the integration of strip-shaped extension plates to be in the protective panels of the headband, from which they preferably guided positively in undercut grooves, pulled upwards are and in the extended state radially in the direction of the upper head means and reach or approximate to them.

The extendable strip-shaped protective plates can be pulled out in the Be latched state.

The possibly existing continuous flexible layer of textile material is in All rule also fulfill a warming function and can therefore over the top Edge of the headband can be extended beyond and such a large top have protruding edge, that when pulled up edge of this textile layer reaches the center of the head and the edges of the two opposite Pages of the headband can be fixed against each other to move Type of cap to close the top opening of the headband.

If not required, the protruding edge becomes outward over the outer surface or worn inwardly folded over the inner surface of the headband.

In the pulled up, so the opening occlusive state can by means of this edge the integrated, partially removable from the protective plates, but still in these guided, strip-shaped extension plates automatically pulled out, e.g. with their free front ends are attached to a corresponding location of this edge.

Side views of further details,

1a and 1b show the protective tape 1 in the worn state on the head 20 of a User in the supervision or in a vertical section.

In Fig. 1b it can be seen how the band 1 at about the height of the widest point like a headband on the side of the head.

In Fig. 1a it can be seen how the individual, interconnected Protective plates 2 existing guard band 1 around the entire circumference extends and the finite band at one point, preferably in the forehead, with its ends 1a, b fixed against each other, for example by means of Velcro 6, in which the over all protective plates 2 outside continuous textile outer layer 5, with all the protective plates 2 firmly connected, in particular glued or sewn, is formed longer at one end 1a outside and with a sufficiently large Velcro surface on the opposite surface of the other end 1b is fixed.

In Fig. 1a, the direct connection of the successive protective plates. 2 by means of joints 7, which are located on the outside of the plates 2, around the plates at any point by 180 ° back to back with the outside to be able to fold against each other, as for the flat transport state, for example, as in Fig. 2a two-ply with the length of a half headband, is shown.

Preferably, as in FIG. 1 a, they are supported against the oppositely directed one Narrow sides the protective plates 2 then against each other, if the measure of maximum possible curvature of the protective tape 1 is reached in the worn state.

The individual plates 2 are on their inner side 2a with a cushion layer 4 made preferably foamed plastic or a textile material assigned to the desired cushioning but also warming effect for the user to offer.

If the connection of the ends 1a, b of a finite headband against each other by the direct connection, z. B. by means of the releasable joints of the first with reached the last protective plate 2, so must for the purpose of size compensation on or several additional protection plates can be interposed.

As the limited movable joints are formed, is freely selectable:

Co-aligned bearing lugs 7a, b and through to be plugged and also removable hinge pin according to Fig. 1c, is possible as well as a limited articulated latching connection according to FIG. 1d, in which the latching lug 17 of the one Protective plate 2 has a thickened end and in a corresponding, undercut Detent recess 18 of the next protective plate 2 can be pressed. there are locking lug 17 and locking recess 18 preferably linear along the against each other directed outer edges of the protective plates 2 in particular opposite surfaces (inside or outside), arranged and into each other latchable.

Fig. 1a also shows the curvature 9 'of the individual protective plates 2 viewed in the top view, while Fig. 1b shows a similar curvature in the vertical, the However, both are not necessarily prerequisites, but especially of the Depend on the size of the protective plates 2:

Since a size of the protective headband 1 is similar to a conventional Headband should be, the height, ie width B, the headband and thus the individual protection plates 2 between 7 cm and 10 cm while off Due to a good adaptation to the curvature of the head 20 in the circumferential direction measured length L of the plates 2 either rather lower, between 3 cm and 7 cm, especially between 4 cm and 5 cm, will fail, especially if identically designed and therefore equally long elements over the entire Scope 10 should be used.

Preferably, however, it is more preferable to use at least two different ones Lengths of protective plates, of which the shorter in the range of greater curvature (e.g., temples area or as an initial piece or piece) for length compensation), while the longer ones in the areas lesser curvature (side of the head) can be used.

To the optical differences to a conventional headband as possible low, yet a good compromise on the market To achieve protective effect, the thickness D of the protective plates without padding between 5 mm and 15 mm, in particular between 8 and 12 mm.

In Figs. 1a and 1b is further shown that the outer side 2b of the protective plates 2 is covered with a textile outer layer 5, the different functions has to fulfill:

If the protective plates 2 are directly concatenated against each other in the direction of rotation, the outer textile layer 5 serves primarily for optical alignment with a conventional one textile headband, and can for these reasons in a technically simple way and Way, for example by flocking the outer sides 2b of the protective plates 2, getting produced.

However, a very cost-effective solution can be achieved rather by the fact that the protective plates 2 are not connected directly to each other, but over the with the outer sides of the protective plates 2 firmly connected outer textile layer 5, which for this purpose either endless ring passes or in turn finally is formed as connectable to a ring band.

Especially in the endless training must be as size compensation, the textile outer band 5 have sufficient extensibility, while at a finite Band and connecting the ends with z. B. a Velcro 6 of the Velcro this length compensation offers and that the textile outer layer. 5 even in the direction of rotation 10 not extensible or chosen only very slightly stretchable can be.

A smaller thickness of the protective headband is achieved by all Functions, namely connection of the individual protective plates 2 with each other, Padding function between protective plates 2 and head 20, as well as heat function is laid in an inner circumferential textile inner layer, on the outside the protective plates 2 - then fixed without additional outer panel - are, but then clearly visible.

In particular, when an elongation of the inner or outer carrier tape gaps between the protective plates 2, these are preferably in thickness formed partially overlapping each other, such as in Figs. 3a and b and 4a shown.

At least in the middle height range, the protective plates 2 'are in this case e.g. the inside along the one connecting edge one inwards to the connecting edge towards open recess 22, while over the opposite terminal edge 21 protrudes near the inner surface of a correspondingly shaped extension, which extends into the recess of the next plate 2 'into it.

In addition to avoiding gaps, even with a stretched outer layer 5, distributed this construction punctually occurring forces on the surface of more than one Guard plate 2 'and reduces the surface pressure against the head 20 again.

In addition, in such a construction - yes after attachment of the connecting Layer as outer layer or inner layer - as shown in Fig. 3b the protective headband 1 are bent in a simple manner by folding the connecting e.g. Outer layer 5 by 180 ° against each other as in Fig. 3b represented, whereby the protective headband 1 in a two-ply flat transport position can be spent.

FIG. 2b shows how special ear protection plates 2, 2 'are used in the area of the ears which differ from the other protective panels of the headband, that they on their inside 2a a downwardly open recess 12 for receiving the upper ear half.

In addition, an ear flap 13 can be accommodated on or in this ear protection flap 2a be folded down as cold protection over the lower half of the ear 19, can be lowered or swung down, depending on whether the accommodation takes place in the plate 2 "or on the outside, and of which material the ear flap 13 is made.

The problem of lifting such earflaps 13 by the wind during Skiing is best remedied by the at least one earflap comprising at the lower edge encircling bracket 13a, e.g. vertically upwards in the protective plate 2 "hineinschiebbar and in the extended state still is stored in this far, that a lateral lifting by wind not is possible.

On the other hand, Fig. 4a shows another solution by at individual the Protective plates 2 to e.g. the lower edge another, either identical protective plate 2 or specific approach protection plate 2 "'can be attached.

This is by simple, even in one piece with the rest of the protective plate 2 turn Trainees to be formed, either as shown in Fig. 1d, also possible as by locking elements, which by turning the two parts against each other be secured, as shown in Fig. 4b:

In this case, one or two T-shaped projecting at the one connecting edge Connecting elements 23 at right angles to the main plane of the other plate 2 in corresponding lying in the main plane, also T-shaped recesses 24th are inserted, whereby by subsequent pivoting of the two plates 2, 2 "to each other in a common main plane, the T-shaped locking element 23rd held in a form-fitting manner in the undercut recess 24 of the other plate is, so that a mutual release of the two plates 2, 2 "no longer possible is, as long as they are in a common aligned plane.

Although such approach plate 2 "'can also serve the purpose of the heat function of Ohre 19, but above all the possibility, at the lug plate 2 "', in particular at its lower edge, in each case the end of a chin guard 14 to attach, which leads arcuately at a distance in front of the chin of the user and in falling forward the lower jaw and teeth from injury should protect.

Of course, the lug plate 2 "'and the protective plate 2 carrying it Protective headband are integrally formed with each other, giving stability The design increases, but this is for different purposes only useful if a connection of the protective plates 2 of the headband 1 is selected, in which each protective plate 2 detached individually from the protective headband and can be replaced by another, for example a normal one Protection plate 2 "in the ear area by a downwardly extended protection plate for attaching the chin guard 14th

1a, 1b also shows, as in the individual protective plates 2 upwards pullable, web-shaped protective webs 2 c can be moved out to protect the Head top on this abutment, and again made of impact resistant Plastic and possibly a cushion layer 4 on the inside.

When used as a protective headband they remain in the protective plates 2, if necessary, however, at any time above in the extended Position in which they still have connection and guidance in them Protective plates 2 have pulled out and there also optionally locked become.

This function is particularly simple when the free ends of the webs 2c with a corresponding point of the extended beyond the top edge of the protective plates textile outer layer 5 or inner layer 4 'are connected. So long the e.g. textile outer layer 5 with its upwardly projecting edge 5a z. B. pushed together along the upper edge of the protective plates 2 remains or even folded over the outside, the webs 2 c remain automatically in the retracted position.

When folding up the edge 5a in the direction of the head center, however, the 2c webs automatically moved to the extended position by their free ends connected to the edge 5a at the appropriate location, z. B. sewn are.

Fig. 3c further shows that the protective plates 2 in the region of their lower edge fastening means 25, in particular positive fastening means 25, for fastening a spectacle 15 at the lower end of the protective plates 2 may have. Preferably, the spectacles 15 can be made of a flexible, foil-like, transparent plastic, the flat in the relaxed state, however is flexible, and therefore can be easily transported.

The curvature for the function as glasses 15, which should also prevent the wind, is only a result of a sufficiently stable film material of the glasses 15 ensures that its upper edge at the lower edges of some or all of the corresponding Protective plates 2 can be inserted in the front area.
