Abstract

The present invention relates to a helmet, especially a plastic protective helmet for cyclists, and to a method of manufacturing it. To achieve the object of the invention, to provide a plastic helmet which can be produced at a considerably lower manufacturing cost, but with increased resistance to loading, it is proposed to manufacture the helmet in dual-wall (2, 3) construction from blow-moulded plastic. Furthermore, means are to be provided, which bring about a reinforcement of the walls (2, 3) of the helmet (1) relative to one another under compression loading, it being possible for these means to be implemented, preferably, in the form of openings (e.g. 30). <IMAGE>
