Patent number: 11547879Abstract: A gas mask, for use with a gas filter or with a demand oxygen system, includes an elastic mask body, a connector and a counter-support. The elastic mask body is configured to be placed over the mouth and the nose of a user of the gas mask. The connector is attached to the elastic mask body and is configured to fix a gas filter or an end piece of a tube in a mount of the connector. The counter-support is attached to the elastic mask body and has a contact area for a support projection of the connector. The connector and the counter-support are arranged such that a force exerted on the connector in a direction of the user acts on the contact area of the counter-support at least partially via the support projection. The support projection is integrated at the connector by manufacturing in one piece.Type: GrantFiled: January 17, 2020Date of Patent: January 10, 2023Assignee: Dräger Safety AG & Co.

Patent number: 6145770Abstract: In a friction coupling for the torque-limiting transmission of force between a core of a coil for winding or unwinding a tape and a rotary support for said core there is a first coupling component with an annular cross-section and a second coupling component taking the form of a moulding, in which the annular coupling component is in frictional engagement at several spaced contact points distributed over its periphery with contact area regions on the moulding, and in which one of the two coupling components is secured to the core of the coil, and the other coupling component is a component of the rotary support. The moulding is rigidly dimensionally stable while the annular first coupling component is made of a flexible material. On the occurrence of a relative movement between the two coupling components, the moulding continually deforms the annual coupling component via the contact points.Type: GrantFiled: May 12, 1999Date of Patent: November 14, 2000Assignee: Pritt Produktionsgesellschaft mbHInventors: Christoph Manusch, Wulf Herrmannsen, Olaf Balke
