Abstract: A protective helmet has a helmet shell and with an interior fitting subassembly having at least one supporting cage, a head band and a neck band. Three supporting arms can serve to fasten the subassembly to the helmet shell with a spacing. A clearance can thus be 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 for obstacles such as branches and the like. The supporting arms can 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.
