A protective helmet has an outer shell, a protection shield movable relative to the outer shell between a deployed position and a stowed position, and a linkage mechanism for connecting the protection shield to the outer shell and permitting movement of the protection shield between the deployed and stowed positions. The linkage mechanism has a first link with a first end connected to the outer shell and a second end connected to the protection shield, a second link having a first end connected to the outer shell and a second end connected to the protection shield, and a biasing member having a first end connected to the first link and a second end connected to the second link. The second end of the biasing member moves between the first and second ends of the second link during movement of the protection shield between the deployed and stowed positions.
