Definitions

  • the present invention relates to an interior system for a protective helmet, in particular a ballistic protective helmet or an impact protective helmet and a corresponding protective helmet.
  • Protective helmets in particular ballistic protective helmets and impact protection helmets, are used in a variety of ways by the police and military. They protect the wearer from head injuries caused by indirect or direct fire and fragments or from blunt head injuries caused by impact.
  • An inner system of a protective helmet should ensure an optimal fit of the protective helmet.
  • interior systems for protective helmets are known. It is crucial for effective protection that the safety helmet always has a central fit, regardless of the head size of the wearer. This cannot be achieved with the existing indoor systems.
  • a protective helmet often sits rear-heavy in the case of medium-sized and small heads, and the head is shifted forward when the size is adjusted. As a result, the helmet sits unbalanced and unsafe, so that optimal protection cannot be achieved.
  • the protective effect of such protective helmets is often limited by critical weak points.
  • interior systems were fastened to the helmet shell by means of bolts or screws engaging in the helmet shell.
  • bolts or screws engaging in the helmet shell reduce the protective effect of the helmet.
  • a bolt or screw can develop into a secondary projectile when fired on, which can seriously injure the head.
  • the material of a projectile although a solid, behaves like a liquid at high velocities and under the high pressures encountered on impact. In the event of an impact, the projectile can therefore "run through” even small gaps between the bolt/screw and the bore or thread in the calotte and thus directly injure the wearer's head.
  • a further object of the present invention is therefore to improve the protective effect of a protective helmet.
  • An interior system prevents the head from being pushed forward when the size is adjusted, since the headband is designed to be essentially circumferential. As a result, the head of the wearer is essentially clamped in from all sides when the size is adjusted. In this way, an ideal fit (best fit) with a central fit (best balance) can be achieved, even if the helmet itself is only available in one size (one size fits all). Also, no replacement pads are required for size adjustment. Furthermore, the size can be set very quickly (Quick Size System).
  • essentially means that the headband is configured circumferentially, with the exception of insignificant intermediate elements, such as cushioning elements or adjustment elements.
  • essentially circumferentially means circumferentially at least 65%, preferably 75% of the circumference of an oval shape around which the headband is placed.
  • the headband preferably has a width of at least 1 cm, preferably at least 1.5 cm, most preferably at least 2 cm. This ensures a stable hold on the wearer's head.
  • the headband may comprise leather or synthetic leather, or a synthetic material.
  • the headgear may be knitted, warp-knitted, or woven, or may comprise a non-woven material.
  • the headband can be covered with leather or synthetic leather, and a core of the headband can comprise a flexible polymer (plastic). This combination is particularly comfortable and durable.
  • the adhesive elements can be physically separated from one another. It is possible that the adhesive elements overlap, but there can also be gaps be formed between the adhesive elements. Furthermore, several adhesive elements (a multiplicity of adhesive elements) can also be designed as an integral adhesive element. The designations first, second, third adhesive element only serves to distinguish the corresponding area.
  • the protective helmet can be, for example, a ballistic protective helmet or an impact protective helmet.
  • the described advantages of the invention have a particularly great effect for ballistic protective helmets and impact protective helmets.
  • ballistic protective helmets and impact protection helmets there are also completely different problems than is the case, for example, with lighter helmets such as bicycle helmets or helmets such as are usually worn on construction sites.
  • lighter helmets in particular, balance is of less importance than is the case with a (in many cases heavier) ballistic protective helmet or impact protective helmet.
  • Concepts that are known from bicycle helmets or "construction site helmets" cannot therefore be readily transferred to ballistic protective helmets and impact protection helmets.
  • An adhesive element is an element that can be attached to another object by means of an adhesive connection.
  • An adhesive connection can be an adhesive connection, for example.
  • the first, second, or third adhesive element can be used to attach the inner system to a helmet shell via an adhesive connection.
  • the first, second, third, or each additional tab can be designed to be elongated. This enables optimal access to the adhesive element.
  • the first, second, third, or any other tab may be integrally formed with the headgear, or attached thereto, such as by a rivet, a stitch, a hook and loop fastener, or otherwise.
  • a first, second, third, or each additional tab can be welded to the headband (eg by a plastic/ultrasonic welding process). All three configurations (integral molding, attachment, or welding) fall under the term "connected". An attachment allows a particularly simple replacement of defective components. An integral or welded configuration, on the other hand, is particularly resistant and durable.
  • An engagement or reach-through element can include a bolt, a screw, a rivet or the like, in particular for engaging or reaching through into or through a helmet shell.
  • a detachable adhesive connection can include a Velcro connection, for example.
  • hard connecting elements such as rivets
  • a detachable adhesive connection can be sufficiently strong so that the protective helmet can remain on the wearer's head even under great stress, for example in the event of an impact or being shot at.
  • the circumference of the headband can be adjusted by an adjustment system, the adjustment system being operated by a rotary knob.
  • the adjustment system can include a gearwheel and/or a toothed rack, for example. This allows the user to easily adjust the circumference of the headband to the size of their own head. For example, this can be done with one hand and blindly, i.e. without having to remove the helmet.
  • the adjustment system can be mounted in a back of the head area. This allows easy access and efficient adjustment.
  • the first strap prefferably has a first connection point, the headband being connected to the first strap at the first connection point; wherein the first tab further comprises a second connection point, wherein the first tab is adapted to be connected to the first adhesive element at the second connection point, and wherein the first connection point is spaced from the second connection point such that the headgear is floating over the first flap can be attached to the first adhesive element.
  • the third strap prefferably has a fifth connection point, the headband being connected to the third strap at the fifth connection point; wherein the third tab further comprises a sixth connection point, wherein the third tab is adapted to be connected to the third adhesive element at the sixth connection point, and wherein the fifth connection point is spaced from the sixth connection point such that the headgear is floating over the third flap can be attached to the third adhesive element.
  • first tab to the first adhesive element directly or indirectly at the second connection point.
  • first intermediate element can be present, as will be described below. The same applies accordingly to the second tab and the third tab or additional tabs.
  • a shock-absorbing effect can be achieved by the floating arrangement, since a cap can be moved relative to the inner system, since the headband is fastened to one or more of the adhesive elements in a floating manner. Furthermore, an optimal balance (best balance) is achieved in which the protective helmet is always held in a central position. For example, when the headband is shortened, the headband is pulled toward the wearer's head by its floating attachment to the one or more adhesive elements. The effect of this is that when the headband is shortened, the head is not pulled in a certain direction, for example forwards, and the balance would thus be adversely affected.
  • first tab is attached to a first intermediate element at the second connection point and wherein the first intermediate element can be releasably adhesively attached to the first adhesive element, so that the first tab can be indirectly attached in releasably adhesive connection to the first adhesive element .
  • first intermediate element can be releasably adhesively attached to the first adhesive element, so that the first tab can be indirectly attached in releasably adhesive connection to the first adhesive element .
  • the first flap may be sewn to the first intermediate member at the second connection point.
  • Such a connection is advantageous in that it does not include hard elements that could injure a wearer's head, yet allows for a stable and durable connection.
  • the second flap and/or the third flap can be sewn correspondingly to the second or third intermediate element (namely at the fourth or sixth connection point).
  • first, second and/or third tab can be fastened to the first, second, or third intermediate element at the second, fourth, or sixth connection point via rivets. This advantageously enables a rotatable connection, which can contribute to greater wearing comfort and better absorption of shocks.
  • the detachable adhesive connection of the first and/or the second and/or the third adhesive element can comprise a Velcro connection.
  • the inventors have found that this is a particularly advantageous embodiment. Without restricting the subject matter of the invention, it is assumed that a Velcro connection is very resistant to transverse forces and is therefore particularly well suited. While it is relatively easy to detach a hook and loop fastener by pulling an element in a direction perpendicular to the connection interface, such a force is very rare when using a safety helmet.
  • the Velcro connection may include a hook strip and a corresponding fleece strip (or felt strip).
  • the first, second, or third adhesive element comprise a hook tape and the first, second, or third intermediate element a corresponding loop tape.
  • the arrangement can also be reversed. This achieves good adhesion and a flat profile with low weight.
  • the Velcro connection may include a mushroom head strap and a corresponding velor strap, which enables stronger adhesion.
  • the Velcro connection may include a mushroom head strap and a corresponding fleece strap, which enables particularly good resistance to lateral forces.
  • the Velcro connection can have extruded hooks or mushrooms include knitwear.
  • the first, second, or third adhesive element can comprise hooks and the first, second, or third intermediate element can have knitted fabric. A particularly high wearing comfort can be achieved as a result.
  • the Velcro connection can include non-combustible materials or be impregnated in such a way that it is non-combustible. This ensures that the wearer's head is protected even in situations where there is an acute risk of fire.
  • the interior system may further include a head net.
  • a head net ensures that the distance between the head and the skull above the head does not become too large or too small, even when the size is adjusted (an example of Best Fit).
  • the headnet can be attached to the headband. This has the advantage that the head net can be adjusted together with the headband, thus ensuring an optimal fit for different head sizes.
  • the head net can be arranged in a central area, for example, and can be completely or partially surrounded by the headband.
  • at least one first head net attachment element is attached to the head net or the head net is formed integrally with the first head net attachment element, the first Head net attachment element passes through an opening in the headband.
  • This arrangement has the advantage that the headband can also be attached directly to the calotte (see below) if the inner system is used in a protective helmet that includes a calotte.
  • the first head net attachment element can have a first area and a second area, it being possible for a detachable adhesive connection to be created between the first and the second area.
  • This releasable adhesive connection may comprise a hook and loop connection as described herein. This allows connection to the headband without connection to the dome if desired. For example, a particularly high dynamic mobility of the interior system can be achieved in this way, which can be preferred for certain applications.
  • headgear fastening elements can be attached to the headgear, for example a first, second, third and fourth headgear fastening element. It is possible for several headgear attachment elements to pass through the same or different openings in the headgear.
  • the head net may also be attached to at least one of the first, second, third, or fourth strap. This has the advantage that the head net can move together with the flap and thus ensures an optimal hold even with dynamic movement sequences.
  • the first adhesive element and the corresponding first tab can be adapted for arrangement on a left side on a protective helmet.
  • the second adhesive element and the corresponding second tab can be adapted for arrangement at the rear of a protective helmet.
  • the third adhesive element and the corresponding third flap can be arranged for arrangement on a right side on a protective helmet.
  • the fourth adhesive member and corresponding fourth tab may be adapted for placement on the front of a protective helmet. It is particularly advantageous if the head net is attached to the second strap (back) and the fourth strap (front). This provides the best stability while still allowing the head net to move with the size adjustment.
  • the head net can be at least partially knitted, warp-knitted or woven, or comprise a non-woven material.
  • the headgear preferably includes a plurality of openings to allow air to circulate between the wearer's head and the headgear.
  • the head net can comprise a spacer fabric.
  • a spacer fabric is understood to be a three-dimensional fabric in which two opposite surfaces are connected by spacer connecting elements. This makes the padding and ventilation particularly effective.
  • the head net can comprise at least one flat band.
  • a flat ribbon is a textile whose width is significantly greater than its thickness.
  • Preferably a flat ribbon is at least three times as wide as it is thick, more preferably at least five times as wide as it is thick, most preferably at least ten times as wide as it is thick. The advantage of this is that the flat strap improves head positioning, as this gives the head net additional rigidity.
  • the headnet may include at least first and second flat bands, the first flat band and the second flat band being substantially perpendicular to each other.
  • Substantially perpendicular means here that two intersecting edges of the first and second flat bands form an angle of between 45° and 135°, more preferably 60° and 120°.
  • the first longitudinal axis may be substantially front to back.
  • the second longitudinal axis may be substantially right side to left side.
  • Substantially means, within the limits of the art, variations for soft components of interior systems for protective helmets, which include variations of about 20°.
  • the first and/or second band may have a width of at least 1 cm at most 6 cm, preferably at least 1.5 cm and most preferably at most 5.5 cm at least 2 cm and at most 4 cm.
  • the greater the width the greater the rigidity of the head net. However, too much rigidity can also be undesirable, as this can reduce the accuracy of fit again.
  • the invention further relates to a protective helmet comprising: (a) a calotte, (b) an inner system as described herein, (c) wherein each of the adhesive elements of the inner system is attached to the calotte.
  • the protective helmet therefore benefits from the described advantageous effects of the inner system.
  • it offers good balance (Best Balance), a good fit (Best Fit), can be adjusted quickly (Quick Size) and can be made in a single size and yet be used by a variety of people with different head sizes (One Size Fits Alles).
  • the protective helmet can be a ballistic protective helmet or an impact protective helmet.
  • the cap can therefore be designed to be bullet-resistant or impact-resistant.
  • Bullet-inhibiting is understood to mean an inhibiting effect on the effects of projectiles or fragments (for example shrapnel). Furthermore, the cap can ensure a protective effect against cutting and stabbing weapons.
  • each of the adhesive elements is fastened to the cap without an element engaging or reaching through the cap. This can prevent an encroaching or penetrating element developing into a secondary projectile under fire or injuring the head when struck.
  • Each of the adhesive elements can be attached to the cap via an adhesive connection. As described, this improves the protection of the head against injuries.
  • the first, second, third or fourth tab can be Y-shaped, ie have three connection points. It is possible that the first, second, third or fourth tab has a connection point to the headband and two connection points to the corresponding adhesive element (also indirectly via an intermediate element).
  • the Y-shaped configuration has the advantage that a torsionally stable connection is created. Therefore, with rotational movements of the head, the inner system rotates directly with and does not "slip" . This also serves to improve the protective effect by providing a better grip.
  • the first adhesive element and the corresponding first tab can be arranged on a left side on the protective helmet.
  • the second adhesive element and the corresponding second tab can be arranged at the rear of the protective helmet.
  • the third adhesive element and the corresponding third tab can be arranged on a right side on the protective helmet.
  • the fourth adhesive element and the corresponding fourth flap can be arranged at the front of the protective helmet. It is particularly advantageous if the second tab (rear) and the fourth tab (front) are Y-shaped. As a result, the helmet is particularly effectively secured against lateral up and down movement towards the head position.
  • the head net can also be attached directly to the calotte via at least one first head net attachment element, with "directly” in this context meaning that the first (and possibly second, third, fourth, etc.) head net attachment element is directly attached to attached to the calotte (i.e. not just via objects in between, such as the headgear).
  • the headgear is not a headgear fastener. This direct attachment to the calotte has the advantage that the head net does not increase in volume when the headband is reduced in size. This results in a better fit and more stable fit of the safety helmet, which is retained when the size is adjusted.
  • the headgear may be attached to a left side of the calotte via a first headgear fastener and attached to a right side of the calotte via a second headgear fastener. This attachment has the advantage that it is very stable.
  • the head net can additionally be attached to a left side of the calotte via a third head net attachment element and attached to a right side of the calotte via a fourth head net attachment element.
  • the first head net attachment element can be arranged on the left rear, the second head net attachment element on the right rear, the third head net attachment element on the left front and the fourth head net attachment element on the right front of the calotte.
  • This type of attachment is very torsion-resistant, i.e. stable, even when the head rotates.
  • At least one of the first, second, third and fourth headgear attachment elements can be passed through--respectively--a first, second, third and fourth opening, for example each in the form of a gap, in the headband.
  • the first and second headgear fasteners can be passed through a first and second gap, respectively, in the headgear.
  • the head net is attached to the second flap (back) and the fourth flap (front). This has the unexpected synergistic effect of further stabilizing the internal system as a whole without further negatively impacting adaptability to different head sizes.
  • the protective helmet may further include a damper ring.
  • the cushion ring may cover part of the headband on an inside, i.e. the side facing the head. It is possible that the damper ring only covers part of the headgear. Preferably the cushion ring covers at least 30%, more preferably at least 50%, most preferably at least 60% of the headgear.
  • the damper ring is therefore not necessarily circumferential. However, the damper ring can be designed to be circumferential in order to offer maximum comfort. The damper ring improves the wearing comfort and the protective effect of the safety helmet considerably.
  • the damper ring is attached to the headband. This has the advantage that even when the headband is adjusted, the headband is always (at least partially) covered by the damper ring.
  • the dampening ring can comprise a foam.
  • the damper ring may comprise ethylene vinyl acetate copolymers, EVA. This offers advantageous damping properties and low abrasion.
  • the damper ring can have a plurality of ventilation cams and projections which are arranged in an alternating manner. This improves the ventilation of the head and thus the wearing comfort.
  • the protective helmet can also include a belt system, with the belt system being attached to the cap by means of a detachable adhesive connection.
  • a belt system can be designed independently of the interior system. This means that the belt system is always attached to the calotte at different points than the inner system. This advantageously increases the setting options for the wearer. As described, the detachable adhesive connection of the system improves the protection of the head against injuries.
  • the position information left/right, top/bottom, front/back is always described in the direction of view of the wearer of the protective helmet and not from the point of view of a third party looking at the helmet from the outside.
  • This configuration enables the safety helmet to be seated stably and the wearer to have a wide range of adjustment options.
  • each of the straps described is separately adjustable in length.
  • the belt system may include a Y-shaped belt, in which a belt strap is fastened to the helmet shell in a rear area, which belt splits into a left and right belt toward a front area of the helmet shell.
  • a clasp may be attached in the chin area.
  • a padding for example a piece of leather, can be fitted under the closure.
  • Padding for example a piece of leather, can also be attached under the left and right front straps in order to further increase the wearing comfort.
  • a cushion for example a piece of leather, to be attached under the rotary knob of the adjustment system, which is used to adjust the circumference of the headband.
  • Each of the mentioned upholstery elements in particular a left upper upholstery element, a right upper upholstery element, a rear and/or a front upholstery element can comprise a ventilation channel. This has the advantage that the ventilation and thus the wearing comfort is improved.
  • the calotte may comprise titanium. Titanium enables excellent protection with a low weight at the same time. The applicant has succeeded in optimizing the manufacturing process for caps that include titanium to such an extent that they are practical.
  • the calotte comprises PE-Titanium, Aramid-Titanium, PE-Carbon-Aramid or similar hybrid configurations.
