EP3027073B1 - Head-protecting cap - Google Patents

Description

The invention relates to a head protection cap, in particular for occupational safety. Furthermore, the invention is directed to a head-cap assembly with such a head cap.

Head protection caps are already known from the prior art, the rigid shells are equipped on the inside with padding elements, on the one hand to allow comfortable wearing the head caps and on the other hand to offer an extremely high protection against shocks. These upholstery elements may be formed, for example, by foam bodies, sponge rubber bodies or spacer fabrics. A disadvantage of these known head protection caps that they are very expensive to manufacture. On the other hand, they no longer provide adequate protection when the upholstery elements have been removed. The DE 10 2007 028 759 A1 discloses a protective helmet with a helmet outer shell. In the roof area, the outer shell has an absorber trough, which is covered by a separate absorber arrangement. The absorber arrangement is formed by an absorber plate, absorber plate-side torsion sleeves and outer shell-side rigid pins. When a force from above the absorber arrangement, the torsion sleeve is pushed axially onto the rigid pin, which leads to its rotation. As a result, the torsion sleeve is plastically deformed and absorbs impact energy. The production of this known helmet is complex.

From the DE 1 732 210 U is a crash helmet with a suspension known. The helmet has a top and a bottom and an interposed, resilient centerpiece. The center piece comprises flat iron, which are interconnected by coil springs.

From the DE 10 2006 058 782 A1 is a head guard with a hard shell known. The hard shell is adapted to be adapted to the head shape and / or size of the user at its back of the head area.

The invention is therefore based on the object to provide a head cap, which is on the one hand extremely inexpensive to produce and on the other hand offers the carrier an extremely high level of protection. Furthermore, the head cap should be particularly flexible. A corresponding head-cap assembly is also to be supplied. This object is achieved by the features specified in the independent claims 1 and 15 features. The essence of the invention is that a shock-absorbing arrangement is provided with at least one shock-absorbing spring device which comprises at least one bridging web extending between two connection bodies arranged in pairs. The at least one connecting web is at least partially resiliently displaceable for shock absorption. It is displaced when there are external forces acting on it, such as an impact or impact. It is advantageous if the at least one connecting web for shock absorption is largely displaceable.

It is also advantageous if the at least one connecting web springs back into its rest or initial position after the action of the external impact force. Preferably, the at least one connecting web itself is to some extent flexible or resilient, which then leads to increased shock absorption.

The at least one connecting web preferably runs straight or curved outwards.

Conveniently, the head cap is symmetrical with respect to a plane of symmetry.

It is advantageous if the shell body also has lateral side areas for at least partially covering the head sides of a head-cap carrier.

The shell body is preferably rigid or intrinsically stiff. Conveniently, this is formed of a plastic material.

It is useful if the shock-absorbing arrangement is firmly connected to the shell body.

Preferably, the head cap in a cap, especially a cap, inside usable. It is useful if the head cap is also removed from the cap again. An individual adaptation is possible.

The one-piece design of the shell body and the shock absorbing arrangement allows an extremely simple and cost-effective production. It is advantageous if the shock-absorbing arrangement and the shell body made of an identical plastic material, for example by injection molding, are integrally formed. Alternatively, these are made of a different plastic material, for example in the two-component injection molding process. Preferably, therefore, the at least one connecting web, the connecting body and the shell body executed in one piece or sprayed. If present, the at least one stiffening element is preferably designed in one piece with the at least one connecting web. Preferably, the at least one stiffening element is injection-molded onto the at least one connecting web.

Further advantageous embodiments of the invention are specified in the subclaims.

The embodiment according to the dependent claim 2 leads to a head cap with an extremely high protection.

The training according to the dependent claim 3 offers the head-cap wearer an extremely high level of protection. The at least one shock-absorbing spring device thus has a particularly large maximum travel.

In the dependent claim 4 a preferred placement of the shock-absorbing arrangement is given. Alternatively or additionally, this is arranged in the front end region, the rear occipital region and / or the lateral side regions.

According to the dependent claim 5, the at least one shock-absorbing spring device is perpendicular to a direct connecting line between the frontal region and the occipital region. Alternatively, the at least one shock-absorbing spring device extends obliquely or parallel to a direct connecting line between the front region and the back of the head region.

The specified in the dependent claim 6 embodiment allows targeted deformation of at least one shock-absorbing spring device in the occurrence of external forces. Furthermore, a controlled deflection or displacement of the at least one connecting web via the at least one connecting body is thus also possible. It is expedient if external forces are damped primarily by displacement of the at least one connecting web by deflection of the at least one connecting body and only secondarily are damped by deformation of the at least one connecting web.

The embodiment according to the dependent claim 7 allows a particularly targeted and controlled shock absorption.

The same applies to the dependent claim 8. It is useful if the two angles are identical. Preferably, these are right angles.

The training in the dependent claim 10 again results in an extremely high travel for the at least one connecting web. Furthermore, this leads to a particularly high wearing comfort.

The at least one stiffening element according to the dependent claim 11 leads to an increased protective effect for the head-cap carrier. The at least one stiffening honeycomb is preferably open to the head receiving space. In cross section, these may be round, oval, angular or the like. Combinations are possible. Preferably, a plurality of stiffening honeycombs are provided at each connecting web. Instead of at least one stiffening honeycomb, at least one stiffening rib, a stiffening insert or the like is present.

The specified in the dependent claim 12 arrangement of the at least one stiffening element leads to a head-cap, which is visually very appealing. The at least one stiffening element is thus substantially invisible or hidden from the outside.

According to the dependent claim 13 more of the shock-absorbing spring devices are present. It is advantageous if at least three, more preferably at least five, more preferably at least ten shock-absorbing spring devices are provided. Conveniently, there are less than 30, more preferably less than 20, more preferably less than 15 shock-absorbing spring devices. It is expedient if the shock-absorbing spring devices are each arranged at a distance from each other and essentially have an identical distance from each other. Other arrangements are possible.

The embodiment according to the dependent claim 14 allows an extremely simple and cost-effective production. It is advantageous if the shock-absorbing arrangement and the shell body made of an identical plastic material, for example by injection molding, are integrally formed. Alternatively, these are made of a different plastic material, for example in the two-component injection molding process. Preferably, therefore, the at least one connecting web, the connecting body and the shell body are made in one piece or injected. If present, the at least one stiffening element is preferably designed in one piece with the at least one connecting web. Preferably, the at least one stiffening element is injection-molded onto the at least one connecting web.

a view that in the Fig. 5 and 6 shown head-cap from below.

Hereinafter, a head-cap assembly will first be described in its unloaded normal state. The head-cap assembly comprises in its entirety an outer cap 1 and a head-cap 2 inserted therein. The cap 1 is preferably made of a flexible material, such as a textile material, formed while the head cap 2 is designed essentially inherently stiff and made of a plastic material. The head protection cap 2 inserted in the visor cap 1 increases the protection of the head of a head cap wearer from external mechanical influences.

The visor cap 1 comprises a deformable visor cap shell 3 and a screen 4 adjoining it at the front, which is preferably rigid to some extent. The cap cap shell 3 defines a receiving space 5, while the screen 4 protects from light, in particular sunlight, or from mechanical influences from above. The screen 4 may comprise at least one stiffening element.

In the receiving space 5 of the visor cap 1, the head protection cap 2 is inserted from below. The head cap 2 is fixed in the receiving space 5. At least one corresponding holding means (not shown) is provided on the cap cap shell 3, which is, for example, a hook-and-loop fastener element, a hook, a push button, a latching means, a holding strap, a receiving bag or the like. The head protection cap 2 is preferably fixed locally by folding over the headband (not shown) arranged on the cap 1.

The head cap 2 in turn comprises a shell body 6, which is adapted to the cap cap shell 3 in size and shape substantially. In the inserted state of the head protection cap 2, the shell body 6 is arranged directly adjacent to the cap cap shell 3. The shell body 6 is preferably at least partially inside on the cap capsule shell 3.

The shell body 6 has a front end region 7, a rear behind-head region 8, an upper-head region 9 and two mutually opposite side regions 10.

In the inserted state of the head protection cap 2, the end region 7 is arranged adjacent to the umbrella 4 of the cap 1. When the head-cap assembly is properly worn, the forehead portion 7 is located adjacent the forehead of the wearer of the head-cap assembly.

At the front area 7, the upper head region 9 connects directly. When the head-cap assembly is properly worn, the top portion 9 covers the top of the wearer of the head-cap assembly.

At the top of the head 9, the back of the head area 8 connects at the rear. This is arranged substantially opposite to the end region 7. When the head-cap assembly is worn properly, the occipital region 8 at least partially covers the occiput of the wearer of the head-cap assembly and the head-cap, respectively.

A side region 10, which is thus provided between the end region 7 and the occipital region 8, extends laterally from the upper head region 9 in each case. The side regions 10 are each formed by at least one segment body 11. In this embodiment, each side region 10 is essentially formed by two segment bodies 11, which are separated from one another by a separating recess 12. Another number of segmental bodies 11 is alternatively possible.

The head protection cap 2 is designed symmetrically with respect to a plane of symmetry 13 which extends centrally between the side regions 10.

The shell body 6 is made in one piece. The forehead area 7, the occipital area 8, the upper head area 9 and the side areas 10 are thus connected to one another in one piece. The shell body 6 defines a head-receiving space 18 which serves to receive the head of the head-cap assembly and the head cap.

The head cap 2 also has a shock absorbing assembly 14 that includes a plurality of shock absorbing spring devices 15. The shock-absorbing spring devices 15 each have an identical structural design. They can differ in size from each other.

Each shock-absorbing spring device 15 has two identical connection body 16, which are integrally connected to the shell body 6 and arranged in pairs. Here, the shock absorbing assembly 14 is provided substantially in the upper head portion 9. It also extends slightly into the forehead area 7 and into the occipital area 8. Other arrangements are alternatively possible.

Furthermore, each shock-absorbing spring device 15 has a connecting web 17, which extends like a bridge between the associated connecting bodies 16. The connecting webs 17 are elongated and preferably resilient. They essentially have a constant width in the direction of the forehead region 7 or the occipital region 8. The plane of symmetry 13 passes centrally through the shock absorbing spring means 15th

The connection body 16 project from the shell body 6 to the outside. They are each carried out stepwise. The connection body 16 of a shock-absorbing spring device 15 extend starting from the shell body 6 slightly together. They each have a width in the direction of the end region 7 or the back of the head region 8, which corresponds to the corresponding width of the associated connecting web 17.

Each connection body 16 has a first connection part 19 connected directly to the shell body 6 and a second connection part 20 connected directly to the associated connection web 17. Between each first connection part 19 and each connection part 20, there is arranged a step part 21.

The connecting bodies 16 of a shock-absorbing spring device 15 run in the region of their first connecting parts 19 starting from the shell body 6 slightly obliquely together or obliquely to the plane of symmetry 13. The first connecting parts 19 are designed plate-like.

The step parts 21 are designed plate-like. They close on the inside to the respective first connection part 19. The step parts 21 of a shock-absorbing spring device 15 run obliquely from the first connection parts 19 in the direction of the plane of symmetry 13. The step parts 21 are each made shorter than the first and second connection parts 19 and 20, respectively. The connection body 16 jump in the step parts 21 on the one hand obliquely in the direction of the plane of symmetry 13 and on the other inwards in the direction of the head-receiving space 18th

The second connecting parts 20 are designed plate-like. The connecting bodies 16 of a shock-absorbing spring device 15 run in the region of their second connecting parts 20 starting from the step parts 21 slightly obliquely together or obliquely to the plane of symmetry 13. The second connecting parts 20 are substantially inwardly offset to the first connection parts 19th Between The second connection parts 20 and the associated connecting webs 17 each have an obtuse angle ws.

The first and second connection parts 19, 20 of a connection body 16 run essentially parallel to one another. Between the first connection parts 19 and the adjacently arranged step parts 21, a right angle wr1 is essentially present in each case. Between the step parts 21 and the adjacently arranged second connection parts 20 there is in each case a substantially right angle wr2.

The connecting webs 17 are shorter than the distance between the first connecting parts 19 of a shock-absorbing spring device 15 in the shell body 6 to each other.

At each connecting web 17 stiffening honeycombs 22 are arranged on the inside, which are open in the direction of the head-receiving space 18 and are integrally connected to the respective connecting web 17. The stiffening honeycombs 22 are preferably arranged side by side in rows and / or columns. They are conveniently identical. In this embodiment, the stiffening honeycombs 22 are hexagonal and define an interior 23 laterally outward.

Through the connection body 16, the connecting webs 17 extend substantially outwardly offset to the shell body. 6

Each shock-absorbing spring device 15 is associated with a recess 24 which is provided in the shell body 6. The recesses 24 are arranged substantially directly below the respective connecting web 17 in the shell body 6. The recesses 24 extend between the first connecting parts 19 of the shock-absorbing spring devices 15. It is advantageous if the recesses 24 are each slightly wider than the connecting webs 17 in the direction of the end region 7 or the occipital region 8. The individual recesses 24 are separated from each other by transverse webs 25 of the shell body 6. The transverse webs 25 extend substantially parallel to one another and perpendicular to the direct connecting line between the end region 7 and the occipital region 8. The course of the transverse webs 25 corresponds approximately to the course of the adjacently arranged connecting webs 17. A transverse web 25 and the adjacently arranged connecting web 17 run, for example identically curved or straight. The transverse webs 25 have a width in the direction of the end region 7 or the occipital region 8, which is smaller than the corresponding width of the adjacently arranged connecting webs 17. Preferably, these are only about half as wide.

The head protection cap 2 also has windows 26, each of which is bounded inwardly by the transverse webs 25 and outwardly by the connecting webs 17 and laterally by the connecting bodies 16. The windows 26 extend substantially perpendicularly outward to the shell body 6. Through the window 26 and the recesses 24 an extremely good ventilation is possible, resulting in a high level of comfort.

When the head protection cap 2 is inserted into the visor cap 1, the connecting webs 17 extend immediately adjacent to the visor cap 1. It is advantageous if the connecting webs 17 rest against the cap cap shell 3 at least in regions on the inside. The free edges 27 of the shell body 6 terminate substantially adjacent to the free ends of the visor cap 1 and the free edges 27 are set back relative to these.

Hereinafter, the head-cap assembly will be described when an external force acts on the shock-absorbing assembly 14 toward the head-receiving space 18. The force acts on the cap cap shell 3 transmitted to the head cap 2. The connecting webs 17, on which this force acts, are bent or displaced inwardly towards the head receiving space 18, at least in regions. At least one of the connecting body 16 of the displaced connecting web 17 is also deflected. Preferably, both associated connection body 16 are deflected. It is preferred if the affected connection body 16 are deflected substantially uniformly. When deflecting the connection body 16, the connection body 16 of a shock-absorbing spring device 15 move relative to each other.

A deflection of the relevant connection body 16 can take place at a first connection region 28 between the shell body 6 and the corresponding first connection part 19. The first connection region 28 then virtually forms a first joint region. Additionally or alternatively, a deflection of the corresponding connection body 16 can occur at a second connection region 29, which between the associated connection web 17 and the corresponding second connection part 20 is present. The second connection region 29 thus forms a second joint region. Alternatively or additionally, deflections of the connection body 16 between the first connection part 19 and the step part 21 may occur at a third joint region 30. Alternatively or additionally, deflections may occur between the second connection part 20 and the step part 21 in the case of a fourth joint region 31.

The deflection is essentially dependent on the direction and magnitude of the force. The applied area also plays a role.

The connecting webs 17 can submerge in the recesses 24 partially, if the force is large enough. The windows 26 change their shape during the action of force.
