Abstract

A collapsible helmet including an elliptic headband and an arc-shaped strap hingedly attached to the headband, the strap extending laterally across the crown of a wearer when deployed in its upright operative position so as to define a head protecting shell and lying co-planar with the headband when deployed in its folded inoperative position so as to define a relatively thin compact package. The helmet further includes a pair of arc-shaped ribs hingedly attached to the headband, the pair of ribs extending longitudinally across the crown of a wearer when deployed in their upright operative positions and lying co-planar with the headband when deployed in their folded inoperative positions. The helmet still further includes a face guard hingedly attached to the headband, the face guard extending laterally across the chin of a wearer when deployed in its downward inclined operative position and lying co-planar with the headband when deployed in its folded inoperative position.
