Abstract: A respiration system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and a first data communication system, and a respiration facepiece including an interface to which the pressure regulator is removably attachable, at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of a wearer; an inspiration port in fluid connection with the pressure regulator interface and in fluid connection with the interior of the facepiece and at least one display within a volume of sealing engagement with the face of the user that is within the field of view of the user. The pressure regulator interface includes a second data communication system to receive data from the first data communication system to control the at least one display. A sealing attachment may, for example, be formed between the pressure regulator and the interface of the facepiece.

Abstract: A respiratory half-mask, including a mask body having a front or side filters, and exhalation valves, a head support with two side straps emanating from support, and a strap guide part fastened on the mask body for sliding the mask body along the side straps from a usage position for covering a mouth and a nose of the user into a position for exposing the face of the user. At least one clamping element is adjustably attached to the strap guide part for clamping the side straps to the strap guide part and for fixing the mask body on the two side straps in a usage position.

Abstract: A blow filter device for breathing masks and hoods, comprising a blower which is driven by a motor and at least one filter which is arranged upstream from the blower, in addition to an electronic control system for adjusting a predefined airflow volume. The invention is characterized in that the motor is an electronically commutated direct current motor (6) which is controlled with the aid of a pulse width modulation ratio as a control variable, wherein a calibrating curve is created and stored in the memory (14) of the electronic control system and is based on a plurality of different filter resistances and a respectively corresponding pulse-width modulation ratio (PWM) and the respective motor speed (n) for a specific volume of air.

Abstract: The invention relates to a mask body for a respiratory half-mask, having a substantially rigid installation plate (4) incorporated into the soft elastic material of the mask body (1) and comprising a fastening cylinder (8) integrally molded thereto, having latching tabs (9) and pivot-proof projections (10) for the production of a stable, removable plug-in connection to a holding device that is connected to a strap. The connection of the installation plate to the mask body material is carried out by means of a narrow connecting strip (12) that is integrally molded to the circumference of the installation plate in one piece, having cutouts (7) provided therein, which are interspersed by the mask body material surrounding the connecting strip (12) such that the strongly stressed installation plate is incorporated into the mask body material in a form-fitting and bonded manner.

Abstract: The invention relates to a respiratory half mask with side straps (4) attached to a head support (3) and forming a single loop, a strap guide part (2) that is connected to a mask body (1) being held on said straps during an usage position on the face or in a position that is removed from the face and displaced downward, comprising a clamping element (26) that is attached to the strap guide part (2) for clamping the side straps (4) to the strap guide part (2) and for securely fixing the mask body (1) in the usage position.

Abstract: In a respirator mask in which the visor panels can be covered by light-absorbing supplementary panels, first and second snap-in hooks are molded onto opposite sides of the visor panel and a stop is molded onto a corner section to form a guide pocket. The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel, it is first fastened in the guide pocket and on the first snap-in hook. Then the opposite side is locked into the second snap-in hook after flexing the supplementary panel.

Abstract: In a respirator mask in which the visor panels (1) can be covered by light-absorbing supplementary panels (5), first (7) and second (8) snap-in hooks are molded onto opposite sides of the visor panel and a stop (6) is molded onto a corner section (3) to form a guide pocket (4). The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel (5), it is first fastened in the guide pocket (4) and on the first snap-in hook (7). Then the opposite side is locked into the second snap-in hook (8) after flexing the supplementary panel. The supplementary panel system has a low overall height, is simple and cost-efficient. Attachment is simple.
