Claim 0:
1. A collapsible protective helmet comprising:
an impact-resistant base body configured to encircle the head of a wearer,
an impact-resistant crown defining a rim portion,
coupling means coupling the crown to the base body, wherein the crown is configured to be movable relative to the base body between a protective position in which the crown is supported by said rim portion on the base body in an orientation in which the crown is configured to cover the top of the head of the wearer when the helmet is worn, and a stored position, wherein the crown is inverted relative to the protective position and in which the crown is supported by and nested in the base body, and, a releasable locking means for locking the base body and the crown together in each of the protective position and the stored position of the crown, the coupling means being configured to permit movement of the crown so that without detachment of the crown from the base body the crown is movable between the protective position and the stored position by pivotation of the crown relative to the base body in a direction away from the base body about a first axis of the coupling means, so as to no longer be supported by the base body in the protective position, and rotation of the crown relative to the base body about a second axis of the coupling means, through 180 degrees, and pivotation of the crown relative to the base body in a direction back towards the base body about said second axis so that the crown is inverted relative to said orientation in the protective position and supported at its rim portion on the base body in the stored position.
