Embodiment Construction

[0018] figure 1 and 2 Shows a perspective view and a front perspective view of an air filter 10 with a flat extension along which it can be inserted into the flow cross-section of the ventilation device 14 in a manner that will be described in more detail below. 12 in. The ventilation device 14 is here part of the heating and / or air-conditioning system of the motor vehicle and comprises an air conditioning box or an air filter box, in the region of which a throughflow for the air filter 10 is provided. Cross section 12.

[0019] Such as figure 1 As shown, the air filter 10 has in the present case a completely surrounding frame wall 16 which has frame wall parts 20 on the respective narrow sides 18 which run arcuately and non-parallel to one another. Corresponding sealing elements 22 are provided on the outer sides of the frame wall parts 20 , which prevent unfiltered leakage air from escaping between the respective frame wall part 20 and the respectively associated wall of...

Abstract

The invention relates to an air filter (10) for a ventilation device (14) of a motor vehicle, having an areal extent along which the air filter (10) can be inserted, transversely with respect to a flow direction, into a flow cross section (12) of the ventilation device (14), and having a filter medium (26) which is arranged along the areal extent of said air filter and which is delimited at least in regions by at least one frame wall (16), which frame wall has at least one recess (28) which, for the guidance of the air filter (10) during the insertion into the flow cross section (12), can be placed in engagement with guide elements (40, 42) of the ventilation device (14), which recess is in the form of a notch on an edge (27) of the frame wall (16) and is of undercut design in relation to the edge (27), whereby it is made possible for the air filter (10) to be supported in two directions transversely with respect to the insertion direction during the insertion process.

Description

technical field [0001] The invention relates to an air filter for a ventilation system of a motor vehicle according to the preamble of claim 1 . Furthermore, the invention relates to an arrangement of such an air filter in the flow cross section of such a ventilation device according to the preamble of claim 9 . Background technique [0002] It is known from DE 10 2005 048 841 B3 to insert an air filter with a flat, drawer-like or cassette-like extension into the flow cross-section of the ventilation device in its direction of extension or transversely to the direction of flow. This air filter comprises a filter medium arranged along its flat extension, which filter medium is bounded in such a way that it is surrounded by the frame wall. A plurality of cutouts are cut out in the frame wall, said cutouts being able to engage / fit the guide air filter with guide elements in the form of guide pins of the ventilation device when inserted into the throughflow cross section.
