    The invention relates to a helmet shell with a net and / or honeycomb calotte body made of plastic.
    Known protective helmets for sports and work are usually constructed of three functional elements, with some applications can be dispensed with one or two elements. The three elements are an outer shell, an impact energy absorbing damping part, as well as a comfort part, which is also used for size regulation.
    The outer shell is usually made of plastic (PP, PUR, etc.), deep-drawn film or fiber-reinforced plastic (possibly a carbon shell) and should on the one hand provide protection against penetration and on the other hand support for visors. The damping part is usually made of expanded polystyrene (XPS, EPS), which is formed as a dome or equal in conjunction with a thermoforming film (cycling helmet) is processed. This element absorbs the energy of an impact and protects the head from traumatic injuries. The comfort part is usually made of a composite of very light plastic foams and a textile and gives a soft seat and can also be used by different strengths for size adjustment. In addition, of course, other functional elements, such as visors, head mounts and ventilation mechanisms, etc. in use. For most types of helmet there is corresponding ISO or EN standard, in which the protection claim and the scope of performance is precisely described and the basis of a certification. The essential functional element 09/11/2011 11:27
    No .: R113 P.003 / 015 09-11-11 ^ 11: 2 6 AM; Paten t anw itskanzle · pretty OPA - £ inlaufstel e; +43 (O) 73 2 7 79-4-1 6 # 4/15 ment is the damping part, which depends on the energy to be absorbed and the maximum allowed delay ( usually 250 g) in the material thickness is defined.
    The material group of polystyrenes available so far leads to material thicknesses that limit the field of vision, cause large contour changes on the head and cause a stiff structure of the helmet. Another major disadvantage of this material group is that the material is destroyed after a single impact and another impact means a high risk by a much lower protection. Experiments with other material groups, such as Polyurethanes were not effective due to the high specific gravity and the associated additional mass.
    The invention has for its object to provide a material which, while maintaining at least the same protective function as a helmet according to the prior art alternatively and / or cumulatively allows a reduction in material thickness to increase the field of view and reduce air resistance, reducing the weight for reduction total head mass and the associated additional pronation risk (whiplash syndrome), optionally a deformation possibility to reduce the volume of the pack, a muffi impact capability to increase the security in a multiple impact, optionally a penetration protection by a deformable foil instead of a heavy shell, optionally a breathability the entire helmet system to prevent heat build-up in the helmet as well as possibly a slight adjustment or no constructive requirement due to flexible structure, and a smaller number of helmet model s.
    The invention solves this problem with the features of claim 1. Advantageous developments of the invention are described in the subclaims. In particular, the invention achieves this object by virtue of the fact that the mesh and / or honeycomb-like calotte body comprises hollow profile-shaped elements arranged in a grid, which are connected to one another via radial webs or are designed as a network structure 09/11/2011 11:28

The transition from net-like structures to honeycomb-like structures can be flowing, which is why the choice of the respective resulting grid structure is left to the skilled person depending on the intended use. The hollow profile-shaped elements may, for example, have a round, a circular, a quadrangular or a polygonal cross-section.
    Particularly advantageous construction and damping conditions arise when the hollow profile-shaped elements of the calotte body are arranged in rows and staggered in rows are staggered. In order to limit deceleration values in the event of an impact, the wall thickness of the tubular elements and / or their connecting webs may also increase towards one side and / or the webs may be recessed relative to the outer end side of the hollow profiled elements.
    If further temperature ranges (for example -20 to plus 50eC) can be covered at least approximately equally well with one and the same helmet, it is advantageous if the calotte body has at least two plastic layers with a temperature-dependent different deformation resistance.
    In order to prevent penetration of the calotte body, the honeycomb-shaped calotte body can be arranged in a shell, preferably made of thermoformable film. For ventilation, the shell may have a plurality of perforations, which preferably have a hole diameter of 0.1 to 5 mm, preferably 1 mm. In addition, the dome on the inside can be equipped with a textile layer.
    To make a flexible helmet without penetration protection, the calotte can be used alone. It is better, however, to equip the calotte on the outside and / or inside with a, preferably breathable, textile layer.
    In order to realize these advantages, a new group of materials has been developed which, due to the shape design and the corresponding material parameters, can be deformed. 09/11/2011 11:29

    (collapsible) calotte results in comparable to the prior art volume weight with reduced material thickness and comparable protective function. In addition, this calotte is multi-impact-capable and breathable. Such a helmet shell consists of a compound of acrylonitrile rubber and at least two organic polymers, wherein the organic polymers are preferably from the material group Polynorbomene, polyvinyl chloride, ethylene vinyl, polyisoprenes, butyl and / or vinyl acetate. Diisononyl phthalate and / or terephthalate are preferably provided as plasticizers, and silicic acid is optionally added as filler. For the production of a helmet cap according to the invention, the expansion jump process is preferably used.
    If necessary, this dome is supplemented by a film which protects against penetration and which has a thickness of only 0.5 to 1 mm, preferably 0.8 mm, and is flexible.
    Furthermore, the comfort element is preferably implemented only by a highly breathable fabric (e.g., COOLMAX®) in combination with a fluffy textile to further reduce home strength. This combination of materials creates a deformable helmet that is self-adapting in size due to its deformability to a certain extent, with which fitting problems belong to the past.
    In addition, wherever the standards do not require penetration protection, a lightweight, thin, comfortable and easily stowable (insertable) helmet / hood solution is possible with a calotte and a textile element, which leads to higher wear acceptance.
    In summary, the product according to the invention is suitable, for example, for use as a damping element, in particular in helmets, protectors (such as back, breast or joint protector), as protective vests, for example for equestrian sports, or even in flexible caps. 09/11/2011 11:29

    A possible use of the product may be the exchange of calotte and comfort element in connection with conventional helmet shells. By the possible use of smaller helmet shells, e.g. XS instead of L, the strength advantage can be implemented without large investments in series and still be generated some significant benefits. In particular, the lower helmet strength with extension of the visual field, reduced total weight, multi-impact and better ventilation through breathable calotte and comfort element.
    By variations in the composition of the plastic according to the invention, the ideal working temperature can be adjusted within wide limits. In addition, a Kalottenkörper consist of at least two plastic layers with temperature-dependent different deformation resistance. When using the damping element for a ski helmet, an ideal working temperature of -20 ° C for one, preferably the inner, and an ideal working temperature at room temperature for the other plastic layer is recommended. When using the damping element for a motorcycle helmet, for example, an ideal working temperature, the temperature range with the best damping behavior, of -20eC for one, an ideal working temperature at room temperature for another and an ideal working temperature of 50 ° C for a third layer is provided.
