AIR DUCT SYSTEM FOR A RAIL VEHICLE OF PASSENGER TRAFFIC
An air duct system for a passenger rail vehicle has a first component venting duct with at least one opening to a second component venting duct and at least one air outlet for ventilating an inner space of the rail vehicle. Furthermore, a membrane that can be held in a formable and/or movable manner is arranged on the air duct system in such a manner that the membrane reduces and or closes the opening and opens the air outlet in a first state and reduces or closes the air outlet and opens the opening in a second state.

11 . An air duct system for a rail vehicle of passenger traffic, the air duct system comprising:
a first part-ventilation duct;
a second part-ventilation duct;
a diaphragm retained in a deformable and/or movable manner;
said first part-ventilation duct having at least one opening formed therein to said second part-ventilation duct and at least one air outlet for ventilating an inner space of the rail vehicle; and
said diaphragm being retained so as to be able to be deformed and/or moved and disposed such that said diaphragm reduces or closes said opening in a first state and releases said air outlet and, in a second state, said diaphragm reduces or closes said air outlet and releases said opening.
12 . The air duct system according to claim 11 , wherein:
said opening in said first part-ventilation duct is one of a plurality of openings disposed over a length of said first part-ventilation duct; and
said air outlet in said first part-ventilation duct is one of a plurality of air outlets disposed over said length of said first part-ventilation duct.
13 . The air duct system according to claim 11 , wherein said diaphragm for reducing said opening has a hole formed therein which has a smaller clear width than said opening.
14 . The air duct system according to claim 11 , wherein said diaphragm contains an air-tight textile or a textile which is coated so as to be air-tight.
15 . The air duct system according to claim 11 , wherein a movement and/or deformation of said diaphragm is brought about in a manner free from foreign energy, simply by changing an air pressure at said diaphragm in the air duct system.
16 . The air duct system according to claim 12 , wherein:
at least two of said air outlets are spaced apart from each other in a longitudinal direction of said first part-ventilation duct;
said diaphragm extends parallel to a longitudinal axis of said first part-ventilation duct at least between said two air outlets and delimits said first part-ventilation duct; and
said diaphragm and said air outlets are adapted to each other such that, in the first state of said diaphragm, for a predetermined total air flow, air flows from both of said air outlets are substantially of a same size.
17 . The air duct system according to claim 12 , wherein:
at least two of said openings are spaced apart from each other in a longitudinal direction of said first part-ventilation duct;
said diaphragm extends at least between said two openings parallel to a longitudinal axis of said first part-ventilation duct and delimits said first part-ventilation duct; and
said diaphragm and said openings are adapted to each other in such a manner that, in the second state of said diaphragm, for a predetermined total air flow, the air flows from both of said openings are substantially of a same size.
18 . The air duct system according to claim 11 , wherein said diaphragm is disposed in the air duct system in such a manner that said diaphragm delimits a cross-section of said first part-ventilation duct for guiding an air flow and in that said diaphragm is retained so as to be able to be deformed and/or moved in such a manner that the cross-section in the second state is smaller than in the first state.
19 . The air duct system according to claim 11 , wherein said first part-ventilation duct is disposed as a roof air duct in a ceiling of the rail vehicle, and in that said second part-ventilation duct is disposed in side walls of the rail vehicle.
20 . The air duct system according to claim 11 , wherein said opening in said first part-ventilation duct is one of a plurality of openings disposed over a length of said first part-ventilation duct.
21 . The air duct system according to claim 11 , wherein said air outlet in said first part-ventilation duct is one of a plurality of air outlets disposed over said length of said first part-ventilation duct.
22 . The air duct system according to claim 11 , wherein said diaphragm for reducing said air outlet has a hole formed therein which has a smaller clear width than said air outlet.
23 . A rail vehicle for passenger transport, comprising:
an inner space; and
an air duct system, containing:
a first part-ventilation duct;
a second part-ventilation duct;
a diaphragm retained in a deformable and/or movable manner;
said first part-ventilation duct having at least one opening formed therein to said second part-ventilation duct and at least one air outlet for ventilating said inner space of the rail vehicle; and
said diaphragm being retained so as to be able to be deformed and/or moved and disposed such that said diaphragm reduces or closes said opening in a first state and releases said air outlet and, in a second state, said diaphragm reduces or closes said air outlet and releases said opening.
