Abstract: A protective helmet adapted to receive and protect a head of a wearer comprises: an outer shell shaped to protect the head of the wearer, with the outer shell defining a bottom opening and an internal cavity for receiving the head of the wearer; a headband and a suspension positioned within the internal cavity of the outer shell; and a visor rotatable between a retracted position within the outer shell to an extended position in front of a face of the wearer, wherein the visor simultaneously rotates about a first pivot axis and a second pivot axis as it moves between the retracted position and the extended position. The visor can also be readily removed from the protective helmet and easily replaced should it become damaged.

Abstract: A protective helmet includes a shell, which defines a bottom opening and an internal cavity for receiving the wearer's head. The shell further includes a brim with a central opening defined in the brim. An attachment mechanism for securing an accessory to the shell includes one or more openings defined through the brim on either side of the central opening, wherein each of the openings includes a larger diameter portion and a smaller diameter portion, which are separated by a detent. Each opening receives a respective boss of the accessory, which can be selectively advanced from the larger diameter portion to the small diameter portion of the opening. Furthermore, the attachment mechanism includes a slot defined in and along the edge of the shell, with the slot corresponding with the central opening defined in the brim, such that the slot is configured to receive a projection extending from the accessory.
