Motor vehicle air filter device and filter element for motor vehicle air filter device

Abstract

The invention relates to an air filter device for a motor vehicle, comprising a housing (12) with a receiving space (14) for a filter element (10). The filter element (10) has a frame (16) which at least partially surrounds a filter material (18) of the filter element (10). The frame (16) comprises a first side wall (20) and a second side wall (22) opposite the first side wall, and a first transverse wall and an opposite second transverse wall (32, 34) connecting the side walls. A first projection (26, 30, 76, 78) projects from the respective side wall (20, 22) near one of the two transverse walls (32, 34). The housing (12) comprises two opposite housing side walls (44, 46), each of which has at least one chute (50, 52, 80, 82, 84, 86), in which a first projection (26, 30, 76, 78) of each side wall (20, 22) of the filter element (10) can be inserted into a chute end region (54, 56, 72, 74, 98, 100, 106, 108) directed in a first direction (64, 102, 104). A second projection (28, 76, 78) protrudes from the side wall (20, 22) in the vicinity of the other of the two transverse walls (32, 34), and wherein the housing side walls (44, 46) each have a second slotted end region (72, 74, 98, 100, 106, 108) which is directed in the opposite direction to the first direction (64, 102, 104) and into which the second projection (28, 76, 78) can be inserted, such that the filter element (10) is located in the receiving space (14) of the housing (12) in the operating position thereof. The side walls (20, 22) can be elastically deformed in such a way that the mutual distance (40) between two projections (26, 28, 30, 76, 78) arranged on the same side wall (20, 22) can be reduced in order to insert the respective second projection (28, 76, 78) into the associated second chute end region (72, 74, 98, 100, 106, 108) along the inwardly directed chute guide side (68, 70, 92, 96, 90, 94) during installation. The invention also relates to a filter element (10) for such an air filter device.

Description

technical field [0001] The invention relates to an air filter device with a filter housing for accommodating a replaceable filter element of a motor vehicle air filter device, wherein the filter housing has two pairs for guiding and supporting the flat filter element The raised chute (Kulisse) on the placed side wall, the filter element consists of a filter web (Filtervlies) held in a frame formed with the side wall. The invention also relates to a filter element for a motor vehicle air filter, which has projections on the side walls. Background technique [0002] In order for the filter element in the housing of the air filter device for a motor vehicle to be able to perform its function reliably, it must be ensured that the filter element is secured tightly and in a positionally stable manner in the housing. [0003] DE 10 2014 004 738 A1 describes a filter element with a box-shaped main body, wherein in the frame wall of the main body made of flexible material there are ...

AI Technical Summary

Problems solved by technology

What can happen at this point is that the walls of the filter frame are not resting correctly against the carrying bosses, but are simply pressed against the bosses

This may not be noticeable especially in the housing area of ​​the air filter unit where the protrusions are not clearly visible

In this way, undesired and also poorly recognizable leaks of the air filter can occur
