Abstract: A protective helmet is described, with a helmet shell and with an interior fitting subassembly which comprises at least one supporting cage, a head band and a neck band. Three supporting arms serve to fasten the subassembly to the helmet shell with a spacing. A clearance is thus provided between the interior fitting subassembly and the helmet shell for receiving ear protection capsules and supporting brackets of an ear protection and of other helmet accessories. When not in use, the ear protection can be pivoted under the helmet shell. The protective helmet therefore does not provide any engagement possibilities whatsoever for obstacles such as branches and the like. The supporting arms partially transmit a force acting on the helmet from above back into the helmet shell in order to elastically deform the latter. The helmet therefore has an improved shock absorption capability.

Abstract: An interior fitting subassembly is described at least consisting of a supporting cage, a head band and a neck band for a protective helmet. Three support arms serve to fasten the subassembly on a helmet shell with a spacing. Although the support arms conduct a force acting on the helmet into the supporting cage said support arms endeavour to deform the helmet shell. The helmet therefore has an improved shock absorption capability. In addition, the support arms create a clearance between the interior fitting subassembly and the helmet shell or receiving ear protection capsules and supporting brackets of an ear protection and other helmet accessories.

Abstract: The invention relates to a device for automatic implementation of chemical or biological methods in sample vessels, more particularly for sequencing and amplifying nucleic acid sequences, including a pipette apparatus and a thermocycler, the pipette apparatus comprising a pipette arm for pipetting sample substances and/or chemicals. The invention is characterized in that the pipette apparatus and the thermocycler are configured as spatially separated workstations and that a handling arm for moving at least one sample vessel containing sample substances or chemicals and configured separate from the workstations is provided.
