The invention relates to an arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person. According to the invention, an arrangement of a plurality of oxygen breathing devices is provided, wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices and a receiver adapted for wireless communication with a sender of said second oxygen breathing device.

The invention relates to an arrangement of a plurality of oxygen breathing devices, in particular for providing oxygen to passenger or crew of an aircraft, each oxygen breathing device comprising an oxygen source, wherein oxygen is stored, in particular in chemically bound form or compressed form, an oxygen guiding device for guiding oxygen from the oxygen source to a person. According to the invention, an arrangement of a plurality of oxygen breathing devices is provided, wherein a first one of said plurality of oxygen breathing devices further comprises an integrated transmitter comprising a sender adapted for wireless communication with a receiver of a second one of said oxygen breathing devices and a receiver adapted for wireless communication with a sender of said second oxygen breathing device, wherein said second oxygen breathing device is arranged in a distance from the first oxygen breathing device, wherein the sender and receiver of said integrated transmitter are adapted to receive and send at least a decompression signal signalising the need to activate oxygen supply from said oxygen source via said oxygen guiding device, and wherein preferably said transmitter is connected to said oxygen source to activate oxygen supply via said oxygen guiding device upon receipt of such decompression signal.

A hinge for a foldable rail section for mounting a container of an oxygen supply unit in an aircraft, with a first hinge part on the rail section and a second hinge part on the edge of the container, and with a container door, which extends in parallel to the longitudinal side of the rail section and is pivotable around a joint on the rear edge of the container. The connection of the hinge to the container is simplified, and a stop is provided for the container door. The first hinge part is formed as of a bead (11), which is made in one piece with sections of the longitudinal side of the rail section (9), wherein slots (12) are present in the sections of the bead (11) not made in one piece with the rail section, and the second hinge part is formed as tongues (13) made in one piece with the rear container edge (4) corresponding to the outer shape of the bead (11), and the said tongues extend into the slots (12), and the tongues (13) are raised at the tongue end (15) such that the tongue ends (15) form a stop limiting the pivoting stroke of the container door.

A device for winding webs of material onto winding shafts comprises a movable bearing supporting a winding shaft during winding, through which the supply roll being formed can be moved towards a contact roller and which can be moved in a position away therefrom for the removal of the completely wound supply roll. A new winding shaft accelerated approximately up to the speed of the web and onto which the cut leading end of the web can be wound, is inserted in the movable bearings. To prevent damage to the web, the weight of the supply roll is supported on the contact roller. The movable bearing is formed by two pairs of holding means, each pair of which can be moved synchronously with the other pair but also independently thereof. The pairs are adapted to hold a supply roll jointly as well as individually to hold a completely wound supply roll or a winding shaft with the leading end of the web wound thereon.

A testing device (1) with a test button (4) and a rod-shaped plunger (5) for testing a locking device that can be actuated on a door (2) pivotable around a hinge on a container (3) is to be improved in terms of simple design and mounting. To simplify design and mounting, a fastening structure (8, 7) for the movable, rotatable mounting of the testing device (1) is arranged on the door (2). The end (13) of the plunger pointing toward the container (3) is provided with a holding structure (14) which is introduced into a mounting support (16) arranged permanently on the container (3) such that the holding structure (14) is out of engagement with the mounting support (16) in normal operation, and in testing operation. The holding structure engages the mounting support (16) in such a way as to limit the pivoting stroke of the door (2).

A breathing mask with a half mask and a nape band is to be improved such that secure contact of the mask in the entire nose and mouth region of the mask user is ensured by the nape band. The mask is thus effectively prevented from slipping despite the fact that the band is located in the nape region only. An additional application of a hood is possible without providing additional holding members. To accomplish this task, the band can be applied in the form of a rubber-elastic cuff (5) which has a neck opening (6) and a head opening (7). The mask and cuff are preferably made in one piece of silicone rubber, and the hood can additionally be bonded to the cuff.

A gas-tight packaging arrangement for a device, such as a respirator containing an oxygen releasing chemical. The arrangement includes a safety device for checking the state of the packaging. The safety device acts on an elastic partial area of an evacuated envelope surrounding the device. The envelope may be made of foil or the like. The state of the packaging is indicated through a viewing window provided on a housing surrounding the envelope. A loss of vacuum is indicated by providing a tensioned non-elastic band surrounding at least part of the circumference of the envelope. The non-elastic band includes a visible mark band part which may be viewed through the viewing window. The visible mark band part includes a breaking point, the breakage of the visible mark band part being visible through the viewing window. To tension the non-elastic band, a strain relief element may be provided bridging the visible mark band part such that the belt may be tensioned without breaking the visible mark band part.
