COMPOSITE PROTECTIVE HELMET

摘要

A composite protective helmet comprises two or more separable and mutually connectable parts that can be interconnected by L-shaped projections on one of the parts and L-shaped recesses on a mating part so that during assembly the L-shaped projections are inserted into the mating recesses and the separable parts are interconnected by shifting one part relative to the other so that elements of the L-shaped projections that are parallel to the mating end faces are inserted into respective parts of the recesses, and then the separable parts of the helmet are locked in the assembled state, e.g., by hooks on one of the parts and a hook-engaging ferrule on the other of the separable parts. The advantage of the composite protection helmet is that after the parts are separated, they can be stored in a relatively small space, e.g., in a top box attachable to the luggage rack of a motorcycle.

主权项

1. A composite protective helmet having a substantially semispherical impact-resistant shell having a front side and a back side, the helmet comprising:
at least a two separable and mutually connectable parts which in the connected state form the semispherical impact-resistant shell and have mating end faces which, when in the connected state of the impact-resistant shell form a division line defined by the mating end faces when the mating faces are in contact with each other, the division line passing along the middle of the semispherical shape in the longitudinal direction of the helmet; a plurality of connecting members for connecting the separable parts formed on the mating end faces of the separable parts, the connecting members comprising L-shaped projections on one of the separable parts and L-shaped recesses on the other of the separable parts, each L-shaped projection comprising a first element that extends outward in the direction perpendicular to the end face of the first mating end face and a second element that extends from the end of the first element in the direction parallel to the end face of said one of the separable parts, while each L-shaped recess on the other of the separable parts comprises a first recess that extends inward into the end face of said other of the separable parts in the direction perpendicular thereto and a second recess that extends from the end of the first recess in the direction parallel to the end face of said other of the separable parts.
