ABSTRACT:
A crash-helmet with a device for locking and releasing movable parts comprising a helmet body and a part which is associated with the helmet body and is movable with respect to the helmet body along a movement path. The device for locking and releasing the movable part comprises a first member, which is associated with the movable part and is provided with engagement regions which are mutually spaced along the movement path, and a second member, which is associated with the helmet body and is provided with at least one retention element which engages at least one of the engagement regions. The retention element is flexible in order to allow the movement of the movable part with respect to the helmet body, sequentially engaging the engagement regions when the movable part moves with respect to the helmet body. The device also comprises a locking member which can engage the retention element in order to prevent its elastic yielding, locking the movement of the movable part with respect to the helmet body, or can be disengaged from the retention element to allow its elastic yielding.
