发明名称 Firefighting hood and face mask assembly
摘要 An apparatus having a face mask removably attachable to a firefighting hood is provided. The face mask used in cooperation with a breathing apparatus such as a self-contained breathing assembly or a respirator. The face mask has a rim supporting a seal member that operatively sealingly engages the user's face providing a breathing chamber between the user's face and the face mask that is sealed off from the external environment. The firefighting hood has a compliant material enclosing the wearer's head and a support frame surrounding a front opening in the firefighting hood exposing the wearer's face. The firefighting hood matingly engages the face mask such that a perimeter portion of the firefighting hood around the front opening is nested behind the rim of the face mask so as to prevent gaps between the firefighting hood and the face mask. A fastener system attaches the face mask to the firefighting hood to retain the nested arrangement of the perimeter portion of the firefighting hood in an attached position of the face mask to the firefighting hood.
