A collapsible helmet (100) for protecting the head of a user, the collapsible helmet (100) includes a left arched member (102), a right arched member (104) and a middle arched member (120). The three arched members are hingedly attached at a front attachment point (114) and a rear attachment point (116) such that the members are deployable between an operative position in which the members form a substantially elliptical protective head cover and an inoperative position in which the members substantially overlap to form a compact package. Flexible attachment straps (138, 140, 142, 144) engaged with each of the members define the relative angular positions of the members when deployed. An alternative embodiment employs a number of ribs (48, 50) hingedly connected to an elliptical band (12) which fold to a generally planar configuration for storage.

L'invention porte sur un casque repliable (100) assurant la protection de la tête d'un utilisateur et comportant un élément gauche courbé (102), un élément droit courbé (104) et un élément central courbé (120). Ces trois éléments sont fixés pivotants en un point de fixation frontal (114) et un point de fixation arrière (116) de manière à permettre aux éléments de se déployer en une position de fonctionnement dans laquelle ils forment une protection sensiblement elliptique de la tête et de se replier dans une position de rangement dans laquelle ils se recouvrent sensiblement et forment un ensemble compact. Des sangles souples de fixation (138, 140, 142, 144) reliées à chacun des éléments déterminent la position relative des éléments en position déployée. Dans une variante, un certain nombre de nervures (48, 50) montées pivotantes sur un bandeau elliptique (12) se replient en une configuration sensiblement plane pour le rangement.
