ABSTRACT:
The invention relates to an adjustable helmet comprising a first and second shell portion adjustably connected together. Each shell features a smooth interference-free sliding surface on which the two shells fit together in an overlapping relationship. The two shells are locked together by a manually operable locking device adapted to engage corresponding anchoring holes. The smooth interference-free sliding surfaces allows easy adjustment of the helmet size.
