A helmet, adjustable longitudinally and laterally to fit a variety of head configurations, includes an outer shell having front and a rear shell parts, which are moveably joined with one another, and an adjuster. The rear outer shell and/or the front outer shell can include first and second lateral shell portions separated by a slot. The adjuster can move the first and second lateral shell portions away from one another from a narrowed mode to a widened mode to increase the lateral dimension of the helmet. Simultaneously, the adjuster can move the front and/or rear shell to increase the longitudinal dimension of the helmet as the first and second lateral shell portions move from a narrowed mode to a widened mode. A method is also provided for effecting the longitudinal and lateral adjustments of the helmet.

L?invention concerne un casque réglable longitudinalement et latéralement pour s?adapter à des morphologies de tête variées, comprenant une coque extérieure dotée de parties de coque avant et arrière mobiles l?une par rapport à l?autre, et un dispositif de réglage. La coque extérieure arrière et/ou la coque extérieure avant comprennent une première et une seconde partie de coque latérales séparées par une fente.
