The disclosure relates to an outer shell (1) for a protective helmet and a method of manufacturing it. In order to be able to manufacture a helmet which has undercut form and which well surrounds the head of the wearer, by injection moulding in as simple a plastic manufacturing tool as possible, the outer shell (1) consists of a plurality of sections (3, 4, 5) which are interconnected with one another via connecting portions (6, 7) the neck and side sections (4, 5) are located, on manufacture, in positions where the helmet shell has no undercut form and, after manufacture, are bent in along the connecting portions (6, 7) for the outer shell (1) to assume its final form. It is also possible to bend the sections (4, 5) proper after the manufacture. The result will be a helmet with at least one undercut area, and grooves (8, 9) and grooves (8, 9) between the sections (3, 4, 5). <IMAGE> |
