A system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and at least one energy transfer element. The system further includes a respiration facepiece including at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of the user, thereby creating a volume of sealing engagement between the respiration facepiece and the user, an opening into the volume of sealing engagement of the respiration facepiece in communicative connection with an interface for removable attachment of the pressure regulator to the respiration facepiece, and an inspiration port in fluid connection with the interface and in fluid connection with the volume of sealing engagement. The pressure regulator interface includes at least one cooperating energy transfer element such that energy can be transferred between the at least one energy transfer element and the at least one cooperating energy transfer element to transfer at least one of data or power into the volume of sealing engagement.

Data communication and displays for breathing apparatus facepieces and pressure regulators

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.

A respiration system includes a regulator including an inlet for connection to a source of pressurized gas and an outlet for delivery of the gas to the user, and a respiration facepiece for use in connection with the regulator including an interface removably attachable to the regulator, at least one seal system adapted to form a sealing engagement with the face of a user, an inhalation port in fluid connection with the regulator interface and with the facepiece interior, an inhalation check valve in fluid connection between the inhalation port and the facepiece interior; an exhalation port in fluid connection with the facepiece; an exhalation check valve in fluid connection with the exhalation port; and an ambient port separate from the inhalation port and from the exhalation port, which is in fluid connection with the facepiece interior without an intervening check valve.

Facepiece with open port

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.

Respiratory half-mask

A holding device for a breathing mask that is fastened to a protective helmet when in use includes a fastening hook connected to a flexible, length-adjustable tightening strap that is hooked into a receptacle on the protective helmet. Stop elements that are both frictionally engaged and in positive contact prevent the accidental release of the fastening hook together with the flexibility of the tightening strap that at the same time ensures an individually adjustable fit of the mask while sliding elements arranged at an offset to the stop elements ensure automatic optimum orientation of the tightening straps. The tightening strap and the fastening hook are coupled using a retainer piece molded to the tightening strap that is held in positive contact in the recess of a grip end connected with the fastening hook.

Holding device for connecting a gas mask to a protective helmet

A strap for respirator masks comprises a head strap piece, made from elastically flexible synthetic material, with a strap fixing piece and a head plate with a greater wall thickness than the attached head straps. A neck strap, connected to the mask at two fixing points and an extending temple strap, which may be introduced in a detachable and length adjustable manner into fixing clips attached to the head straps, are fixing to the strap fixing piece. The head strap piece thus consists of a straight and a curved piece. The crown-shaped embodiment with the elastic temple band is associated with good fitting and wearing properties and low maintenance requirements.

Strap for a full respirator mask

A feeding valve having a hose coupling in the form of an expansion bellows which unfolds automatically into the wearer's field of vision when the sealing cap of the feeding valve is opened, thereby enables a wearer to easily insert the straw of a food or beverage bottle even when wearing protective gloves.

Feeding apparatus for breathing masks that allows food and drink intake when the mask is in use

A connecting part for a breathing mask with an eye-protecting lens has a connecting piece inserted in an opening of the eye protecting lens and supported on a rim at the opening. The connecting piece has a connecting cylinder with holding elements and receptacles to hold the connecting piece on the rim by a detachably fixed U-shaped locking member.
