Publication number: 20220062674Abstract: A breathing half mask, which can be brought by a folding operation from a storage state into a use state. A mouth area is arranged between a nose area (11) with a nose sealing line (41) and a chin area (12) with a chin sealing line (42). A first connection section (14.1, 14.2) connects the nose area (11) and/or the chin area (12) to the mouth area. A second connection section (15.1, 15.2) connects the nose area (11) and/or the chin area (12) to another mask area (10) in order to limit the nose sealing line (41) and/or the chin sealing line (42). The second connection section (15.1, 15.2) extends a distance from an edge of the nose area (11) and/or from an edge of the chin area (12) between the first connection section (14.1, 14.2) and the nose sealing line (41) and/or the chin sealing line (42).Type: ApplicationFiled: December 20, 2019Publication date: March 3, 2022Inventors: Michael ROSERT, Eiko HASEMANN, Mathias SCHOLZ, Katrin HINZ, Alexander GRÜNKE

Patent number: 9492691Abstract: A directional valve for a respirator product includes a valve housing (15) and a valve seat (1) for receiving a flexible valve membrane (16). The valve seat has a circular and essentially flat sealing surface (2) surrounding an opening (3), which is sealingly covered by the valve membrane during an inspiration phase. A fixing lug (13), on the valve housing (15), fixes the valve membrane in the valve seat and is arranged offset in relation to the center of the valve membrane, such that an entire circumferential surface of the valve membrane is lifted off from the sealing surface during an expiration phase. The fixing lug is directed essentially at right angles to a flow plane formed by the opening. A counter-support (25), within the opening, is arranged opposite the fixing lug such that the valve membrane is mounted with fixed clamping action, between the fixing lug and the counter-support.Type: GrantFiled: September 13, 2013Date of Patent: November 15, 2016Assignee: Dräger Safety AG & Co.

Patent number: 6305370Abstract: The invention is directed to a voice transmitter for a breathing protective mask. The voice transmitter includes a membrane housing (2) and a clamping ring (3) which can be connected to the membrane housing (2). The voice transmitter also includes a voice membrane (4) between the membrane housing (2) and the clamping ring (3). The voice membrane (4) has an outer membrane portion (14) which is accommodated at a connecting location between the clamping ring (3) and the membrane housing (2). An inner portion (15) of the membrane (4) is tensioned over an annularly-shaped projection (8) located on the membrane housing (2). The pretensioning of the voice membrane is adjusted in a simple manner in that the clamping ring (3) has an annularly-shaped support surface 13 for the inner membrane portion (15) and that the connecting location is configured as a threaded connection (7, 10).Type: GrantFiled: October 4, 1999Date of Patent: October 23, 2001Assignee: Dräger Sicherheitstechnik GmbHInventors: Michael Rosert, Manfred Gdulla
