<p>A flexible and waterproof envelope (1) is employed which, in a non-use condition, can be reduced to minimum encumbering sizes by bending its parts, to be used for covering and protecting a helmet (5) from atmospheric agents, to be introduced into the said envelope. After having closed the openings on the envelope by means of a hinge (4), the helmet thus protected can be fitted to a fixed, ideally linear part (7) of the same vehicle by means of a cable (6), with an annular closure, which after having been introduced into an envelope bore (2), crosses the two helmet openings, i.e. the front one and the one below it, coming out in correspondence to another bore (3) on the same envelope.</p> |
