Abstract

The safety helmet comprises hard internal and external shells and a shock-absorbent insert. The internal shell forms at its lower edge and on the outside thereof an upwardly-opening trough in which the insert is inserted. The free edge of the trough joins with the lower edge of the external shell above the bottom of the trough. The two shells, together with the insert, form ventilation openings which are lined by portions of the two shells.
The main portion of the internal shell is embedded into the soft-bodied insert, so that it is mainly the insert that contacts the wearer's head, but for the rim portion thereof where the internal shell still surrounds the bottom edge of the insert.
