  • the interior is complex and thus expensive to manufacture.
  • the object of the present invention is therefore to provide a protective helmet which is inexpensive to manufacture and safer and reliable protection of the helmet wearer from injury.
  • a protective helmet comprising a helmet shell, an outer support ring fastened to or inside the helmet shell, an inner support ring attached to the outer support ring by means of at least one connecting part, wherein the outer support ring and the at least one connecting part are integrally formed and / or the inner support ring and the at least one connecting part are integrally formed. Due to the one-piece design of the outer support ring and the at least one connection part or the inner support ring and the at least one connection part or the outer support ring and the inner support ring and the at least one connecting part of the protective helmet can be made inexpensively in the production.
  • the outer support ring, the inner support ring and the at least one connecting part are made of a thermosetting or thermoplastic material in a tool by means of injection molding. Since only a few parts have to be produced, costs can be saved during production and thus the protective helmet can be produced more cheaply.
  • the at least one connecting part is designed as a tab or strut.
  • the at least one connecting part has a joint function in a partial section.
  • the at least one connecting part can thus be pivoted against one another on the one section.
  • the at least one connecting part has a smaller thickness in one part section than in another part section, so that the at least one connecting part in the part section with the smaller thickness is elastic and / or bendable. Due to the smaller thickness in the partial section, the connecting part can be bent in the partial section. In addition, the smaller material thickness can also lead to an elastic property, for example by folding in the subsection is possible.
  • the at least one connecting part is formed in a section as a film hinge.
  • the film hinge may be due to the properties in the subsection take over a hinge or joint function. This may result from a small material thickness and / or the properties of the material in the subsection.
  • the at least one connecting part has a length adjustment device in order to be able to adjust the inclination of the inner support ring to the outer support ring or the helmet shell.
  • the protective helmet has three connecting parts. Two connecting parts are arranged in the front region of the protective helmet and a connecting part is arranged at the rear end of the protective helmet.
  • the length adjustment is arranged on the rear connecting part, so that by means of adjusting the length of this rear connecting part, the inclination of the inner support ring to the outer support ring or the helmet shell can be adjusted. This adjustment option is advantageous for various applications.
  • the inner support ring comprises a length adjustment device.
  • a length adjustment of the inner support ring makes it possible to adapt the helmet to different sizes and / or shapes of a head of a helmet wearer.
  • the at least one connecting part is fastened to the inner supporting ring or the outer supporting ring by means of at least one connecting means.
  • the outer support ring is fastened to the helmet shell by means of the at least one connection means.
  • the at least one connecting means is a rivet and / or a screw and / or a latching connection and / or a Velcro connection and / or a pressure-button connection.
  • a locking connection can be technically executed in different variants.
  • the connecting part formed as a tab may be provided at the end with a latching nose, which engages in a corresponding detent member.
  • a plug and mating connector can be formed with a corresponding latching connection.
  • a complementary variant consists of the helmet shell and / or the inner Support ring and / or the outer support ring and / or the at least one connecting part at least partially made of a, preferably rigid, plastic.
  • the inner and / or the outer support ring is aligned substantially horizontally in a horizontal orientation of a lower edge of the helmet shell.
  • the inner and / or the outer support ring are closed.
  • the circumference of the inner support ring is smaller than the circumference of the outer support ring.
  • the inner support ring is disposed within the outer support ring.
  • the inner support ring and the outer support ring are arranged in an identical plane.
  • FIG. 1 shown in a side view protective helmet 1 serves to protect the head of a helmet wearer from injury.
  • Fig. 1 are an inner and outer support ring 3, 4 shown by dashed lines.
  • the protective helmet 1 comprises a helmet shell 2, the inner support ring 3, the outer support ring 4, and three connecting parts 5 ( Fig. 2 ), which are designed as a tab 6.
  • Fig. 2 only the inner and outer support ring 3, 4 and the three tabs 6 are shown.
  • FIG. 2 illustrated perspective view shows a view of the inner and outer support ring 3, 4 and the connecting part 5 seen from the underside of the protective helmet 1 ago.
  • the inner and outer support ring 3, 4 and the connecting parts 5 are thus opposite to the illustration in FIG Fig. 1 swiveled through 180 °.
  • the inner and outer support ring 3, 4 and the connecting part 5 are arranged in a space enclosed by the helmet shell 2 space.
  • the outer support ring 4 is fastened by means not shown connecting means 10 to the helmet shell 2.
  • the outer support ring 4 at only a few points, ie in this case at three points, attached to the helmet shell 2 in an advantageous manner. As a result, the strength and rigidity of the helmet shell 2 is reduced only very slightly.
  • the inner support ring 3 serves to receive the head of the helmet wearer.
  • the connection between the inner support ring 3 and the outer support ring 4 is made by means of three tabs 6 as connecting parts 5.
  • the three tabs 6 are formed integrally with the outer support ring 4.
  • the tabs 6 are formed on a section 7 with a substantially smaller material thickness than in another section. The tab 6 can thus be bent or bent in the section 7, d. H. it has a joint function and thus also represents a film hinge 8.
  • the outer support ring 4 In the production of the outer support ring 4 with the three tabs 6, which are manufactured in one piece by injection molding of a plastic, the outer support ring 4 is initially arranged in a plane band, wherein the three tabs 6 are arranged in this plane after manufacture , To produce the outer support ring 4, the ends of this band are connected to each other and the band is bent, so that the outer support ring 4 is formed. In order to connect the tabs 6 with the inner support ring 3, they must be bent at the portion 7, so that a geometric arrangement according to Fig. 2 the tabs 6 is possible. The end of the tabs 6 is fastened by means of screws 11 as a connecting means 10 to the inner support ring 3.
  • the film hinge 8 also allows a slight possibility of movement of the inner Support ring 3 relative to the outer support ring 4, because due to the small material thickness in the region of the film hinge 8 a flexibility is easier than in material areas with a larger material thickness. As a result, an impact on the helmet shell 2 can be transmitted to the head of the helmet wearer due to an object impinging there.
  • a length adjustment 9 is formed on the inner support ring 3.
  • the length adjustment device 9 makes it possible to adapt the circumference of the inner support ring 3 to different sizes or shapes of a head of the helmet wearer.
  • the two ends of the inner support ring 3 by means of a mechanical device are movable against each other.
  • a length adjustment 9 may be formed on one of the tabs 6. As a result, the inclination of the inner support ring 3 to the outer support ring 4 or to the helmet shell 2 can be adjusted.
  • the tabs 6 are integrally connected to the inner support ring 3 or made in one piece or in one piece together with the inner support ring 3.
  • the ends of the tabs 6 are analogous to the in Fig. 2 and 3 illustrated first embodiment attached to the outer support ring 3 by means of screws 11.
  • the inner support ring 3 and the tabs 6 are integrally formed.
  • the tabs 6 are aligned substantially exclusively horizontally.
  • the tabs 6 thus do not have a film hinge 8 or a U-shape as shown in FIG Fig. 3 ,
  • the inner support ring 3, the outer support ring 4 and the connecting parts 5 and the helmet shell 2 are made of a thermoplastic or a thermosetting plastic by injection molding.
