Claim:
A system housing ( 30 ), in particular for a heating, ventilating and/or air-conditioning system of a vehicle, comprising: at least a first housing part ( 1 ), a second housing part ( 2 ) and a third housing part ( 3 ) which serve for accommodating system components and for forming air-channeling paths ( 36 , 37 , 38 , 39 , 40 , 41 ), the second housing part ( 2 ) including a first abutment surface and a second abutment surface disposed opposite the first abutment surface, up to which the first housing part ( 1 ) and the third housing part ( 3 ) are each advanced essentially parallel to a normal vector of the respective abutment surfaces on the second housing part ( 2 ), such that the second housing part ( 2 ) is disposed between the first housing part ( 1 ) and the third housing part ( 3 ); and the second housing part ( 2 ) including a first portion ( 20 ) defining a lateral cross section having a generally U-shaped portion ( 20 ) and further including a second portion ( 21 ) defining a lateral cross section having a generally T-shaped portion ( 21 ) cooperating with the U-shaped second portion ( 20 ) to define two air channels therebetween; wherein a leg of the T-shaped portion ( 21 ) defines a generally vertical line of symmetry with the first housing part ( 1 ) and one of the two air channels disposed on one side of the vertical line of symmetry and the third housing part ( 3 ) and the other of the two air channels disposed on an opposite side of the vertical line of symmetry such that the first housing part ( 1 ) is positioned for use as a left-side air-distributor housing, the second housing part ( 2 ) is positioned for use as a central air-distributor housing and the third housing part ( 3 ) is positioned for use as a right-side air-distributor housing.
