ABSTRACT:
A protective helmet is provided with two externally located pockets for receiving fittings adapted to carry accessories. An elongate, resilient arm at each fitting extends towards the front of the helmet, and forms one component in a pivot joint. The face shield is provided with two mounting tabs, to be attached to the elongate arms.
Each pivot joint comprises a stud insertable in a bore, the mounting being facilitated by flexing the resilient arms outwards, and the tab is retained into engagement with the associated arm by a wart at the tab abutting against the shell of the helmet.
At least one of the tabs is provided with a transversely running ledge, and the end of the arm is defined by two side edges arranged at right angles to each other. In an inactive position the ledge rests against one of said edges, which in mounted position runs substantially horizontally. When the shield is swung to active position the ledge abuts against the other edge, the relative positions being selected so the ledge tardily passes the corner between the side edges, when the shield is swung from one position to the other.
