Abstract
A protective helmet with a second shell having a top end connected to a top portion of a first shell such as to allow relative movement between the first shell and the bottom end of the second shell about a connection between the top end and the top portion along two opposed directions. Two connecting members are each connected to a respective side portion of the first shell at a fixed location and are each connected to the bottom end of the second shell through a respective connection allowing relative movement therebetween. An adjustment mechanism is connected to the second shell and has a movable portion movable between an unlocked position free of the connecting members to allow relative movement between the first and second shells and a locked position in engagement with the connecting members to prevent relative movement between the first and second shells along at least one of the opposed directions.
