Definitions

  • the invention relates to an outer shell for a protective helmet with the features of the preamble of claim 1, a protective helmet with such an outer shell and a method for producing an outer shell for a protective helmet having the features of the preamble of claim 1.
  • protective helmets and in particular motorcycle protective helmets have an outer shell for the distribution of impact forces. Such outer shells are used for the areal distribution of the impact forces along the outer shell. A regularly arranged inside the outer shell inner layer then serves to cushion the distributed in this way impact forces.
  • the digital communication of protective helmet wearers and in particular wearers of motorcycle helmets is becoming increasingly important.
  • essential components of the corresponding communication devices can be arranged on the protective helmet or on the motorcycle helmet. From the prior art, and in particular from US Pat. No. 8,667,617, from which the present invention is based, it is known to arrange a wireless communication antenna on the inner layer so as to be supported by the inner layer.
  • the object of the invention is to provide an arrangement possibility for an antenna on a protective helmet, which avoids the above-mentioned disadvantages.
  • This object is achieved with respect to an outer shell for a protective helmet with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.
  • this object is achieved by the features of the characterizing part of claim 9 and with reference to a method for producing an outer shell for a protective helmet having the features of the preamble of claim 13, this object is achieved by the features of characterizing part of claim 13.
  • Essential to the invention is the recognition that the outer shell itself can be used to fix the antenna, by forming a cover for receiving the antenna between the cover and a side of the outer shell.
  • the outer shell Due to its intended function, the outer shell already has the material properties required for such a fixation and mounting.
  • the hard and durable material of the outer shell can thus be used to separate the antenna from the softer inner layer. This also avoids an arrangement of the antenna on the outside of the outer shell.
  • the proposed outer shell is for a protective helmet, which may be in particular a motorcycle helmet, and serves to distribute impact forces.
  • the outer shell according to the invention has an outer shell material and is characterized in that on one side with the outer shell material of the outer shell, the outer shell has a cover for receiving an antenna between the cover and the side, the cover having the outer shell material. It is therefore a side of the outer shell, which side has the outer shell material.
  • cover is understood to mean a structure which is at least partially spaced apart from a base surface of the side and thus forms an opening, in which the received structure - in this case the antenna - between a flat top side of the cover and a flat base beneath the cover
  • This base surface is a partial surface of the above side of the outer shell, whereby this cover side essentially overlaps this base surface.
  • Tenne is received by a formed between the cover and the side of the outer shell opening.
  • the side is an inner side of the outer shell.
  • the inside of the outer shell is the concave side of the outer shell.
  • the side is an outer side of the outer shell.
  • the outside of the outer shell is the convex side of the outer shell.
  • the respective side of the outer shell is meant apart from the cover itself.
  • a preferred embodiment of the proposed outer shell is characterized in that the outer shell material comprises a matrix material for a fiber composite material.
  • a matrix material serves to bind fiber material of the fiber composite material by adhesive or cohesive forces to the matrix material.
  • the matrix material surrounds the fiber material of the fiber composite material. The above bond by adhesive or cohesive forces regularly results from curing or crosslinking of the matrix material, which process can also be referred to as compounding.
  • the outer shell material can also have other materials in addition to the matrix material. However, it may also be that the outer shell material consists essentially of the matrix material. Likewise, it may be that the outer shell material comprises the fiber material or consists essentially of this.
  • the outer shell material comprises a fiber-reinforced plastic with the plastic as a matrix material and a fiber material or even substantially consists of this fiber-reinforced plastic.
  • the fiber material comprises glass fibers.
  • the outer shell material then comprises or consists essentially of a glass fiber reinforced plastic.
  • the fiber material may also be a quantity of different fiber materials.
  • a further preferred embodiment of the proposed outer shell is characterized in that the outer shell material and preferably the matrix material has a duroplastic. It may also be that the matrix material consists essentially of the thermosetting plastic.
  • the thermoset is one or more of the group of vinyl ester resin (VE resin), epoxy acrylate, polyester resin (UP resin), epoxy resin, phenolic resin (PF resin), PVB-modified phenolic resin and styrene-free resin , including derivatives of these substances and of these substances with additives.

  • the cover may be integrally formed with the rest of the outer shell. Likewise, the cover can be materially connected to the rest of the outer shell.
  • a preferred embodiment of the proposed outer shell is characterized in that the cover has an extension which substantially corresponds to the extent of the antenna.
  • the extent of the cover here corresponds preferably to the expansion of the cavity formed by the cover, especially between the cover and the base area below the cover.
  • the cover is adapted to receive the antenna substantially completely between the cover and the side.
  • the cover is open on two, in particular opposite sides. Accordingly, it is preferable that the cover forms a passage between the cover and the side. As a result, it is a tunnel-like structure for receiving the antenna.

  • a corresponding preferred embodiment of the outer shell according to the invention is characterized in that the pocket is open in an opening direction - starting from the interior of the pocket - for insertion of the antenna and is closed in a direction opposite to the opening direction. Consequently, the antenna can then only be inserted into the pocket in one direction of movement - this time starting from outside the pocket - and removed from the pocket only by a movement in the direction opposite to this direction of movement. Passing through the bag is thus not possible.
  • This embodiment again improves the fixation of the antenna in the pocket.
  • the pocket is closed in the two perpendicular to the opening direction aligned transverse directions on the inside of the outer shell.
  • a lead in or out in such a transverse direction is then also excluded.
  • a longitudinal extent of the pocket along the opening direction exceeds a transverse extent of the pocket along the transverse directions.
  • the bag has an elongated shape, which is particularly advantageous if the antenna has an orientation and should also be arranged in a certain orientation to the outer shell.

In particular, this adhesion can be a frictional connection, which is based on a friction between the antenna and the cover. It may be further here that the antenna is received without material fit between the cover and the side. Consequently, the antenna is not glued or similarly fixed between the cover and the side. A comparatively complex processing step for producing such a material bond can accordingly be dispensed with.
  • a film or another structure is respectively disposed between the cover and the antenna and between the side and the antenna.
  • This film or other structure may be, for example, a forming or molding core which is used to form the cover in the manufacture of the outer shell in more detail below and which after manufacture is wholly or partially interposed between the cover and the cover Page remains.
  • a preferred embodiment of the protective helmet according to the invention is characterized in that the antenna has a metallic antenna body and a plastic housing for preferably essentially complete reception of the antenna body.

  • a further preferred embodiment of the proposed protective helmet is characterized in that the antenna is received between the cover and the side so that it can be pulled out, in particular in the opening direction.
  • the protective helmet has an inner layer for absorbing impact forces received from the outer shell, that the protective helmet has an antenna feed coupled to the antenna for connecting the antenna and that the antenna feed line is at least partially between the outer shell and the antenna feed line Inner layer is arranged.
  • the antenna feed line is not used for transmitting or receiving radio signals, ie does not count towards the antenna itself, but merely establishes an electrical connection with the device which uses the antenna for transmitting and / or receiving.
  • this device using the antenna can be any device, preferably either fixed or detachable, connected to the protective helmet.
  • this device is a communication device.
  • a preferred embodiment of the proposed protective helmet is characterized in that the protective helmet has a contact arrangement for electrical connection to a communication device and that the antenna feed line is guided to the contact arrangement for connection of the antenna.

  • these may be different fiber materials, but it is preferred that the first fiber material is identical to the second fiber material.
  • the first one Fiber material and the second fiber material are simply referred to as fiber material.
  • the proposed method is further characterized in that between the side and the cover layer, a mold core is arranged, that a matrix material surrounding the first fiber material of the preform and the second fiber material of the cover layer is cured to form the outer shell, so that on the side of a cover the outer shell is formed with the outer shell material for receiving an antenna between the cover and the side.
  • the outer shell material may comprise or consist essentially of one or more of these materials, the matrix material, the first fibrous material or the second fibrous material. Specifically, therefore, the outer shell material may comprise the matrix material as well as the first fiber material and the second fiber material.
