Abstract
Service panels such as passenger service panels in an aircraft or other passenger conveyance are equipped with fresh air outlets. The air outlets are connected to an air supply duct in such a way that the service panels can be adjusted in their position lengthwise relative to the longitudinal aircraft cabin axis. This purpose is accomplished by making the tap connection between the service panel and a fresh air supply duct adjustable in the axial direction along the air duct while maintaining the proper seal between a tap member and the air duct. The seal is maintained by providing the duct with a slot covered by at least one sealing lip and by providing the tap member with a sealing guide slide that adjustably seals the tap member in the duct.
Claims19
An air supply apparatus, comprising a service panel, an air outlet in said service panel, a hollow air duct, at least one air tap member connected to said hollow air duct for withdrawing air from said hollow air duct, and a position adjustment device for feeding air from said hollow air duct through said air tap member to said air outlet of said service panel, so that said service panel is position adjustable, and wherein said position adjustment device comprises a longitudinal gap in said hollow air duct having at least one elastic sealing lip biased to normally close said longitudinal gap, a sealing guide slide (2, 15) slidingly fitting into said longitudinal gap, said air tap member (10, 16) being carried on said sealing guide slide, said air tap member passing through said sealing guide slide for permitting an air flow out of said hollow air duct through said air tap member into said air outlet of said service panel, said sealing guide slide having at least two guide elements (8, 9) forming at least one sealing slot in which said at least one sealing lip of said hollow air duct is slidingly received in a sealed manner, so that said sealing guide slide is adjustable in its position along said longitudinal gap in said hollow air duct while said sealing lip and said at least two guide elements maintain a continuous seal around said air tap member and between said sealing lip and said hollow air duct.
