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.

La présente invention vise un casque protecteur constitué d'une coque intérieure, d'une coque extérieure et d'un intercalaire amortisseur. Le bord inférieur de la coque intérieure est façonné en forme de gorge vers l'extérieur, par où peut être inséré l'intercalaire amortisseur. Le bord libre de la gorge est relié au bord inférieur de la coque extérieure, en un point situé au-dessus du fond de la gorge. Les ouvertures de ventilation des deux coques sont décalées les unes par rapport aux autres. La partie principale de la coque intérieure est noyée dans l'intercalaire souple, ce qui fait que c'est ce dernier, surtout, qui est en contact avec la tête de l'utilisateur; sur le pourtour du casque, par contre, l'amortisseur est dissimulé entre les deux coques.
