Oxygen emergency supply means
View Patent ↗The oxygen emergency supply device for an aircraft is equipped with a receptacle in which at least one oxygen mask is arranged. The receptacle comprises a lid which opens in the case of release and releases the oxygen mask. Handling device for reaching and applying the oxygen mask and a device for releasing the oxygen supply to the mask are provided. The handling device has at least one arm which in the case of release extends out of the receptacle through the lid opening into a position laterally of the mask drop axis so that the mask may be reached by a person seated laterally of the mask drop axis.
1. An aircraft oxygen emergency supply unit, comprising:
a receptacle;
an oxygen mask arranged in said receptacle, said receptacle comprising a structure with a lid opening and a lid which opens in the case of activation and releases said oxygen mask;
a handling means for reaching and applying the oxygen mask, wherein the handling means comprise at least one arm, including a proximal end that is pivotally connected and a free end, which in the case of activation extends from a position within the receptacle out of the receptacle through the lid opening into a position laterally of a mask drop axis;
a means for activating the oxygen supply to the mask.
2. An aircraft oxygen emergency supply unit according to claim 1 , wherein said handling means includes a guide means arranged at the free end of said arm and extends parallel to the drop direction of the oxygen mask.
3. An aircraft oxygen emergency supply unit according to claim 2 , wherein said guide means comprises a grip part at an end of said guide means, said end being spaced a distance from said arm.
4. An aircraft oxygen emergency supply unit according to claim 2 , wherein said guide means comprises a pull cord for connection to the oxygen mask.
5. An aircraft oxygen emergency supply unit according to claim 1 , wherein said arm comprises a pivot lever.
6. An aircraft oxygen emergency supply unit according to claim 5 , wherein said arm is spring biased in the extension/pivot-out direction.
7. An aircraft oxygen emergency supply unit according to claim 1 , wherein the arm comprises one piece.
8. An aircraft oxygen emergency supply unit according to claim 1 , wherein the arm comprises more than one part.
9. An aircraft oxygen emergency supply unit according to claim 1 , wherein a part of the arm is telescopic.
10. An aircraft oxygen emergency supply unit according to claim 1 , wherein said arm is a part of said lid.
11. An aircraft oxygen emergency supply device, comprising:
a receptacle with an opening;
an oxygen mask arranged in the receptacle and movable to a released location outside the receptacle;
an arm;
a guide line arranged at the free end of said arm and extending in a drop direction of the oxygen mask, said guide including a grip part connected to said guide line and a pull cord, said pull cord being connected to said oxygen mask and said grip part, said arm with said guide line extending from a position within the receptacle out of said receptacle through said opening into a position laterally of the mask drop axis when said oxygen mask is in said released location such that said guide line extends in a drop direction of the oxygen mask at said position laterally of the mask drop axis, wherein said oxygen mask may be reached by a person seated laterally of the mask drop axis via said grip part and said pull cord.
12. An aircraft oxygen emergency supply unit according to claim 11 , further comprising:
a release line connected to the mask for activating the oxygen supply to the mask.
13. An aircraft oxygen emergency supply unit according to claim 11 , wherein said arm comprises a pivot lever.
14. An aircraft oxygen emergency supply unit according to claim 13 , wherein said arm is spring biased in the extension/pivot-out direction.
15. An aircraft oxygen emergency supply unit according to claim 11 , wherein the arm comprises one piece.
16. An aircraft oxygen emergency supply unit according to claim 11 , wherein the arm comprises more than one part.
17. An aircraft oxygen emergency supply unit according to claim 11 , wherein a part of the arm is telescopic.
18. An aircraft oxygen emergency supply unit according to claim 1 , wherein said arm is a part of a lid covering the opening prior to activation.
19. An aircraft oxygen emergency supply device, comprising:
a receptacle with an opening;
an oxygen mask arranged in the receptacle and movable to a released location outside the receptacle;
an arm, including a proximal end that is pivotally connected and a free end, which pivots out of the receptacle through the opening and extends from a position within the receptacle to a position laterally of the mask drop axis when said oxygen mask is in said released location such that the mask may be reached by a person seated laterally of the mask drop axis.
20. An aircraft oxygen emergency supply unit according to claim 11 , further comprising:
a release line connected to the mask for activating the oxygen supply to the mask;
a guide line arranged at the free end of said arm, said guide line extending in a drop direction of the oxygen mask when said arm is in said position laterally of the mask drop axis and when said oxygen mask is in said released location, said guide line including a grip part at an end thereof and a pull cord, said end being spaced a distance from said arm when said arm is in said position laterally of the mask drop axis, said pull cord being connected to said oxygen mask and said grip part such that the person seated laterally of the mask drop axis receives said oxygen mask via pulling said grip part.
