摘要： A method of supplying respiratory air to a user, and a breathing apparatus for this purpose. An inner and an outer mask are provided, the inner mask communicating only with the respiratory passages of the user and the outer mask covering the face of the user. Super-atmospheric pressure is maintained in the outer mask and the outer mask is communicated with the interior of the inner mask during suction created in the inner mask as a result of inhalation. Air flowing from the outer mask into the inner mask is replenished from an extraneous air supply. When the exhalation cycle begins, the communication between the inner and outer mask is interrupted and exhaled air is vented from the inner mask directly to the ambient atmosphere.

摘要： A breathing mask with a fixed, curved mask body and with a mask edge extending around the mask body and adapted to the shape of the face for attaching a sealing edge sealing the mask body against the face and with a supply opening located in the mouth area of the mask body. The mask body provides low-distortion vision along with the largest possible useful field of vision. To accomplish this task, the curvature in azimuthal section planes (5, 6, 7) of the mask body (1) is designed to decrease continuously in the corresponding section plane toward the mask edge (2), starting from a meridian symmetry axis (4) of the mask body; that the azimuthal curvature on the meridian symmetry axis (4) also decreases monotonically, starting from the mouth area (8); and that the meridian curvature of the mask body 1 along the symmetry axis (4) is essentially uniform.

摘要： A head guard assembly comprises a protective head helmet, with a face protective breathing mask coupled to the helmet by interengagement of a coupling pin carried on each side of the face mask with a socket member carried on each side of the protective helmet. The socket member includes a bore which is tapered outwardly in a funnel-shape and is of oval configuration so as to conform close to the inside of the helmet side flaps. It has an interior widened portion in the bore forming catch grooves which are engaged by ball members which are carried in the recess of the coupling member and are biased by a spring into outward engagement with the catch groove when the coupling pin is inserted. The coupling pin includes an uncoupling member which moves against the balls to cause them to be pressed into the recess of the member to permit withdrawal of the mask from the helmet. The socket member is mounted on the helmet by means of a slide which may be slid in directions toward and away from the coupling pin and locked in an adjusted position in order to regulate the interfitting of the mask with the helmet.
摘要翻译：保护头组件包括防护头盔，其具有与头盔相连接的面部防护呼吸面罩，所述面罩与所述面罩每侧承载的连接销相互接合，并在所述保护头盔的每一侧承载承窝构件。插座构件包括以漏斗形状向外锥形的椭圆形构造的孔，以使其靠近头盔侧翼的内侧。在孔的内部加宽部分形成有凹槽，该凹槽由球形构件接合，球形构件被承载在联接构件的凹部中并且当连接销被插入时由弹簧偏压与止动槽向外接合。联接销包括一个脱离构件，该联接构件相对于球移动，使得它们被压入构件的凹部中，以允许面罩从头盔上撤出。插座构件通过滑动件安装在头盔上，该滑动件可沿着朝向和远离联接销的方向滑动并锁定在调节位置，以便调节面罩与头盔的配合。
