Definitions

  • the invention relates to a passenger oxygen mask with the in the preamble of claim 1 specified characteristics.
  • Passenger oxygen masks are provided on board aircraft around the passengers in emergency situations and in the phase of post-decompression flight altitude descent to supply the aircraft with oxygen and passengers who are extra during normal flight operations Need oxygen, therapeutic oxygen available to deliver.
  • Known passenger oxygen masks usually have a rotationally symmetrical Mask body on, whose circular breathing opening the passenger in the application to the facial area around nose and mouths. Because of the circular opening cross section of the Mask body, the passenger oxygen mask is not always complete on the user's face, leaving a gap between Face and mask body remains open and thus permeable to air. Depending on the physiognomy of the face, these spaces are more or less less big. Through this column goes with oxygen masks, the provide a constant flow of oxygen, not insignificant lost a lot of oxygen.
  • Oxygen masks in which the oxygen supply takes place only if one in the mask body arranged valve is opened by the inspiration pulse can be difficult or not activated by the user because of the required to open the valve vacuum in the mask body due to the gaps between mask body and face can not be established. This can cause hypoxia in passengers to lead.
  • the present invention has the object underlying to create a passenger oxygen mask, which the user safely and to a sufficient extent provides oxygen and can be easily and inexpensively manufactured.
  • the passenger oxygen mask according to the invention has a flexible, preferably rotationally symmetrical mask body. At least one Section of the mask body is plastically deformable or provided for receiving a plastically deformable support element.
  • the soft-elastic mask body is preferably rotationally symmetrical and formed with a circular breathing opening. This is special necessary for the operational safety of the passenger oxygen mask, because the oxygen masks so, for example in panic situations, in all Positions can be placed in axis position and used. To a reassurance of the passenger, the oxygen mask, if necessary be positioned correctly. Then it is possible to do the plastic Section of the mask body to deform and so the opening area of the mask body to match the facial contour, whereby the open space between the mask body and the face is minimized or closed.
  • the mask body is in the region of the contact surface to the nose the user formed plastically deformable, since the mask body in this area due to the topography of the face of the rest Facial surface is particularly spaced.
  • the mask body prefferably be annular in the circumferential direction Area formed plastically deformable.
  • This plastically deformable Area is preferably near the breathing opening of the mask body arranged. In this way, the entire contour of the breathing opening adaptable to the contact area with the face.
  • this support element is preferably made of a metallic material educated.
  • the support element is advantageously made of a thin, easily bendable sheet or made of a wire structure, wherein the Dimensions of the sheet or the wire structure of the size of the deformed Mask section are adjusted and a slight deformation enable the support element.
  • a wire structure for example, allows a particularly weight-saving embodiment of the Support element, which improves the comfort of the oxygen mask can be.
  • As material for the support element all metals be used, which ensure that the support element without special Strain can be plastically deformed.
  • the support member is also possible, the support element to make a combination of these materials, this combination also the above-mentioned requirements with regard to plastic Must comply with deformability and dimensional stability. It is conceivable for example, an embodiment of the support element, in which a metallic Wire structure in a basic body made of plastic is cast in the support element. Due to the wire structure of the used plastic in this case also formed elastically deformable be.
  • a pocket for receiving the support element On the outer peripheral surface of the mask body is expediently arranged a pocket for receiving the support element.
  • the Pocket is preferably positioned on the portion of the mask body, when using the passenger oxygen mask above the nose the user is located.
  • the bag is as a slot formed, in which the support element at least partially inserted can be.
  • the bag can be formed by tabs, the support member at least at its spaced ends fix on the mask body.
  • the support element can after a provisional placement of the oxygen mask in a later phase by the passenger or by the flight attendants into the bag are used and then according to the facial contour be deformed in the bag
  • a further preferred embodiment provides that the support element and / or the mask body have adhesive surfaces.
  • This adhesive surface may be the support element after it is on the mask body been positioned and according to the facial contour has been deformed, are fixed to the mask body.
  • the mask-side adhesive surface in the form of a circumferential Is formed rings since then the support element in any position the mask at a suitable location, namely above the nose of User can be attached without the mask before in one certain position to turn.
  • This can also be for the above Embodiments are achieved, for example incorporated in the mask body plastically deformable metal structure is circumferential or the pocket for incorporating the support element is formed by a circumferential lip-like pocket.
  • the passenger oxygen mask have the clamping element and the mask body adhesive surfaces on, which together form a kind of Velcro closure.
  • the mask-side adhesive surface formed circumferentially.
  • the support element and the mask body preferably have adhesive surfaces in the form of nanohide surfaces. These adhesive surfaces exhibit surface structures in the nano range, which during assembly engage each other so that the support element firmly on the Mask body adheres. Also in this embodiment it is expediently, the mask body-side adhesive surface as a circumferential ring train.
  • FIGS. 1 to 3 each show a passenger oxygen mask 2 with one made of a soft elastic plastic mask body 4, which has a breathing opening 6 at a first end. From Fig. 3 is It can be seen that the mask body 4 in its undeformed state is formed rotationally symmetrical in the form of a truncated cone. Corresponding the breathing opening 6 in the undeformed state has a circular Cross-sectional area on. At the of the breathing opening. 6 spaced other end of the mask body 4 are in known The oxygen supply, a savings bag 8 and a secondary air valve arranged.
  • the mask body 4 shown in Fig. 1 has a plastically deformable Section 10 in the vicinity of the breathing opening 6 on. this section 10 extends band-shaped over the entire circumference of the mask body 4.
  • the plastically deformable portion 10 by a arranged inside the mask body 4 embedded metal strips.
  • the metal strip but also inside the mask body 4 or be arranged on the outer wall of the mask body 4.
  • the plastically deformable portion 10 may alternatively also from a plastically deformable plastic, which at the inner or outer shell surface of the mask body 4 is cast or glued is, or is poured into the mask body 4. Furthermore Section 10 may also consist of one or more wires or be formed of a wire mesh. These wires or the wire mesh are then on the inner or outer circumferential surface of the mask body 4 fixed or are integrated in the mask body 4.
  • Fig. 2 shows a passenger oxygen mask 2 through a support element 12 is adapted to the facial contour.
  • the support element 12 both individually and before mounting on the mask body 4 as Also shown as a support member 12 'arranged on the mask body 4.
  • the support element 12 ' is arranged in the region of the mask body 4, in the case of using the passenger oxygen mask 2 covers the nose of the user.
  • the support member 12 in the same place alternatively have an adhesive surface.
  • the Mask body 4 on its outer surface an adhesive coating on, which corresponds to the adhesive surface of the support member 12 and a Fixing the support member 12 on the mask body 4 allows.
  • a pocket 16 is arranged in the passenger oxygen mask 2 shown in Fig. 3.
  • These Bag 16 serves to receive a support member 12 ", which after the correct placement of the passenger oxygen mask 2 in the bag 16 is inserted.
  • the support member 12 " consists of a plastically deformable material, such. B. a plastically deformable Plastic, a metal or a mating of these materials. If the support element 12 "is in the pocket 16, it is deformed, the mask body 4 is adapted to the facial contour.
