Abstract
A protective helmet and a full face mask for combined use on the head and face of a person, comprises a mask which is adapted to fit over the face and has a peripheral portion for encircling the chin, jaws and forehead of the face. The helmet engages over the person's head and has at least one portion adapted to overlie an edge of the mask. The mask has a receiving bearing recess in the overlying portion of the helmet and the helmet has a locking mechanism which comprises a member which is rotatably mounted on the helmet and has a pin which is slidable toward and away from the recess. The pin is urged under spring action into the recess and, when the member is rotated, the pin rides in the recess to pull the mask toward the helmet and toward tighter engagement with the person's head.
