A vehicle heating, ventilating and/or air conditioning device () comprising a housing (), in which at least two hot-air guiding ducts () are formed for different vehicle interior regions, the hot-air guiding ducts () being separated by a housing wall (). A common heating device () and a common air treatment element () are provided which are arranged in each case in both hot-air guiding ducts (), the air treatment element () being arranged in the air flow downstream of the heating device (). The air treatment element () has a dividing wall () which divides the air treatment element () into at least two part regions which are assigned to in each case one hot-air guiding duct ().

Vehicle heating, ventilating and/or air conditioning device

A device for the filtration of an airstream, in particular for a heating and/or air conditioning installation in a motor vehicle. The device provides, on one hand, a filtration that includes as much as possible of the entire airstream, while, on the other hand, for cooling and/or heating purposes, the device provides the entire air-conveying capacity without any air-output losses due to the filtration. The device includes a first outer air-channel containing fixed filter-wall parts of an activated carbon-filter arrangement, and a second inner air-channel containing second filter-wall parts of a particle-filter arrangement. The second filter-wall parts can be pivoted between an opening position which is essentially parallel to the first filter-wall parts and a closure position. Also included is a closure device at the exit of the outer air-channel, such that in the closure position, the entire airstream is conveyed at least through the filter-wall parts.
