Definitions
- the invention relates to a protective helmet with a helmet shell, a support basket and a fastening device for attaching the support basket to the helmet shell.
- Such a protective helmet is known for example from DE 10 2010 097 012 A1. In particular, it serves to protect forestry workers, but is also useful for industrial, construction and sports applications, particularly climbing.
- the disclosure of said publication is also fully disclosure of the present document.
- the requirements for a high-quality protective helmet are manifold.
- the safety provided by the helmet is in the foreground of the requirement profile.
- the helmet is intended to protect the wearer against any type of impact, such as falling objects or branches from fallen trees.
- the helmet has to do different things.
- the helmet shell must be extremely robust to prevent breakage and breakdown of rather small objects, such as stones.
- the helmet shell must also have some deformability to absorb on this basis, the kinetic energy of heavy objects that hit the helmet. The absorption of kinetic energy is less concerned with protecting the helmet-covered head than with making it less likely to injure the wearer's cervical spine.
- the invention has the object of developing a protective helmet in such a way that with high stability of the helmet shell and thereby guaranteed protection against head injuries at the same time an improved protection of the wearer against shocks with high kinetic energy and thus improved protection of the cervical spine are provided.
- the invention is based on the generic protective helmet characterized in that between the support basket and the helmet shell a shock absorption device is arranged.
- a shock absorption device is arranged between the support basket and the helmet shell.
- the helmet shell can thus be optimized to a large extent without special consideration of impact absorption; it must only be sufficiently deformable in order to be able to transmit kinetic energy to the impact absorption device arranged under the helmet shell. The latter then takes over the bulk of the kinetic energy absorption.
- the impact absorption device is arranged at least partially positively against the helmet shell and / or the support basket.
- the positive fit of the impact absorption device on the helmet shell and on the carrying basket ensures that the transferred to the helmet shell on impact kinetic energy acts immediately on the impact absorption and that not about a significant part of the kinetic energy from the helmet shell on the basket and thus transferred to the head of the wearer.
- the impact absorption device is at least partially non-positively arranged on the helmet shell and / or the support basket. It is of particular advantage that the impact absorption device in the case of a blow on the helmet shell shows a substantially plastic deformation behavior. If the impact on the helmet is so severe that it actually results in a deformation of the impact absorption device, it is advisable to replace the helmet. Since the impact absorption device is plastically deformed, one sees the helmet that he has suffered a heavy blow. Due to the plastic deformation behavior is avoided insofar that a possibly damaged helmet unintentionally re-used.
- the protective helmet according to the invention is further developed in a particularly advantageous manner in that the impact absorption device has a multiplicity of cavities which are delimited by walls from one another. Due to the large number of cavities is the Overall, shock absorption device light, so that the comfort of the helmet is not affected. Furthermore, the cavities provide the space required to allow significant deformation of the impact absorption device, which can ultimately lead to significant absorption of kinetic energy.
- the cavities are at least partially formed as tubes.
- these tubes with their ends on the one hand facing the head of the wearer and on the other hand facing away from the head of the wearer, thereby a beneficial ventilation effect can be promoted.
- the tubes consist at least partially of one or more extruded copolymers. Such copolymers can be made extremely thin-walled, yet they provide sufficient stability available. As a result, the requirements of low weight and high stability and good absorption properties can be combined.
- the tubes have at least partially an inner wall and an outer wall which contact each other, the inner wall being stronger than the outer wall.
- the outer wall in this construction of the tubes may be optimized to be connected to outer walls of adjacent tubes.
- the inner wall does the main work of absorbing the kinetic energy.
- the tubes at least partially have an inner wall and an outer wall which contact each other, wherein outer walls of adjacent tubes can be connected to one another by the action of heat.
- the impact absorption device is made of Koroyd.
- Koroyd is a material made of extruded tubes, which consist of copolymers. The tubes are parallel and thermally welded together so that each tube has six neighbors surrounding it. This creates a honeycomb-like structure.
- the tube composite can easily be thermally deformed, laminated, cut or processed in any other way to accept the required shape as Schlagabsorptions worn between basket and helmet shell.
- Koroyd is a trademark of Koroyd SARL.
- the invention is particularly advantageously further developed in that the helmet shell has a further fastening device with which at least one component other than the support basket can be fastened to the helmet shell, wherein the further fastening device is additionally provided as a positioning aid for the impact absorption device.
- the further fastening device can be, for example, two eyelets into which a chinstrap for the protective helmet can be hung. These eyelets can be optimally positioned for the exemplary suspension of the chinstrap, while at the same time setting the position for the impact absorption device during assembly of the helmet. This does not lead to errors in the assembly of the helmet, which in turn increases the overall security.
- the further fastening device prevents a displacement of the impact absorption device between the helmet shell and the support basket.
- the fastening device for attaching the basket to the helmet shell is such that the basket occupies an end position with respect to the fastening device in the use of the helmet and that the basket in the final position exerts a force on the impact absorption, which is a displacement of the Impact absorption device between the helmet shell and the basket prevented.
- the impact absorption device is ideally held in position by the force between the support basket, impact absorption device and helmet shell and by the further fastening device.
- the impact absorption device It is likewise particularly advantageous for the impact absorption device to have grooves on its side facing the helmet shell which form ventilation channels together with the helmet shell.
- the heat balance under a protective helmet is an important topic.
- overheating in the head area of the wearer poses great problems.
- accidents were caused by overheating, which would not have happened without a hard hat.
- This makes wearing a safety helmet an unreasonableity in special situations.
- the ventilation channels in the impact absorption device solve this problem.
- Conventional helmets are common with Foams lined to absorb shocks. These foams are excellent thermal insulators, so that in certain situations, overheating is expected.
- the impact absorption device with its tubes which lead from the head region of the wearer in the direction of the helmet shell, allow ventilation in the direction of the helmet shell, wherein discharged warm air and in particular water vapor can then be forwarded through ventilation channels on the outside of the impact absorption device.
- the climate in the helmet is always balanced, and there are no dangerous situations that could be caused by overheating.
- the ventilation channels communicate with openings of the helmet shell. As a result, air and water vapor, which are guided by the ventilation ducts, pass through the openings in the helmet shell into the open without hindrance.

- the carrying basket 14 sits on the head of the wearer, wherein an intermediate layer, in particular a foam layer, can increase the wearing comfort.
- the support basket 14 is connected via fastening means 16 with the helmet shell 12.
- the connection between the fastening devices 16 and the helmet shell 12 is not directly recognizable, since the side of the helmet shell 12, on which a fastening device 16 can be seen, is itself cut away.
- the interior equipment of the helmet 10 with in particular carrying basket 14 and impact absorption device 18 is symmetrical at least substantially with respect to the cutting plane 30, so that it is clear that the carrying basket 14 is connected to the helmet shell 12 on both sides of the protective helmet 10.
- the impact absorber 18 has grooves 32, 34, 36, 38, 40 on its surface. These serve as ventilation grooves, and they form in that the impact absorption device 18 rests on the inside of the helmet shell 12 together with the helmet shell 12 ventilation channels. The importance of these ventilation channels becomes clear in connection with FIG.
- FIG. 2 shows the plan view according to FIG. 1 with an enlarged detail 48.
