Helmet

A helmet comprising

• a plurality of foamed plastic shell parts,
• plate-like sections integrated within the foamed plastic shell parts, said plate-like sections interconnect in an articulated connection said several shell parts to form a helmet, and some of said several shell parts being connected to a regulatable adjusting system for producing a usable shape of the helmet from an approximately flat configuration of the helmet used for packing purposes.

A helmet comprising

• a plurality of foamed plastic shell parts,
• plate-like sections integrated within the foamed plastic shell parts interconnecting by an articulated connection the individual shell parts as a helmet,
• at least several shell parts being connected to a regulatable adjusting system for producing a usable shape of the helmet from an approximately flat configuration and the shell parts include a central part, a forehead part, a back of the head part and two side parts as five shell parts, which have facing lateral surfaces.

Process for the production of a helmet from foamed plastic with several shell parts and plate-like sections interconnecting in an articulated manner the shell parts, said process comprising

• placing the plate-like sections in a mould, and
• foaming in a single process step the shell parts of the helmet in an approximately flattened, spread-out configuration around the plate-like sections.

Process for the production of a helmet from foamed plastic with several shell parts and plate-like sections forming a radial hinged plate, interconnecting in an articulated manner the shell parts, said process comprising

• placing the hinged plate in a mould, and
• foaming in one process step the shell parts of the helmet in an approximately flat configuration having a spread-out form around the hinged plate.
