SAFETY HELMET
Document Type and Number:
Japanese Patent JPH05279904
Kind Code:
A
Abstract:
PURPOSE: To prepare a safety helmet provided with an internal shell as well as an external shell, in which the internal shell is made of a hard material and it is placed in such a state substantially to line the inside surface of a shock-absorbing linear. CONSTITUTION: The safety helmet comprises hard internal and external shells and a shock-absorbing 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. In one embodiment, the internal shell lines all of the interior face of the helmet. In another embodiment, the main portion of the internal shell is embedded into the soft-bodies insert, so that the internal shell is mainly the insert that contacts the wearer's head, but for the rim portion the internal shell, it still surrounds the bottom edge of the insert.
