Abstract

A filter element for an air filter of a motor vehicle includes a frame part which surrounds a filter material of the filter element. The filter element is insertable into a receiving space which is provided by a housing of the air filter. The filter element has a holding element which is movable from an initial position into a functional position by inserting the filter element in the receiving space. In the functional position, a fastening element can be fixed to the holding element. The fastening element is configured for securing a cover element, which is used to close an insertion opening of the receiving space, to the housing.

First claim

The invention claimed is:

1. A filter element for an air filter of a motor vehicle, comprising:
a frame part ( 16 );
a filter material ( 14 ), wherein the frame part ( 16 ) surrounds, at least in regions, the filter material ( 14 );
wherein the filter element ( 10 ) is insertable into a receiving space ( 28 ) of a housing ( 12 ) of the air filter; and
a holding element ( 36 ), wherein the holding element ( 36 ) is fastened to the frame part ( 16 ) by a flexible connecting strip ( 34 ) and wherein the holding element ( 36 ) is movable, by inserting the filter element ( 10 ) in the receiving space ( 28 ), from an initial position into a functional position in which a fastening element ( 44 , 78 ), which is configured for securing a cover element ( 58 ) used to close an insertion opening ( 52 ) of the receiving space ( 28 ) to the housing ( 12 ), is fixable to the holding element ( 36 ).

2. The filter element according to claim 1 , wherein the holding element ( 36 ) is movable from the initial position into the functional position by a deformation of the flexible connecting strip ( 34 ).

3. The filter element according to claim 2 , wherein the holding element ( 36 ) in the initial position forms a first angle ( 65 ) with a side wall ( 20 , 22 ) of the frame part ( 16 ), which side wall extends in an insertion direction ( 26 ) of the filter element ( 10 ) in which the filter element ( 10 ) is insertable into the receiving space ( 28 ) and wherein the holding element ( 36 ) in the functional position forms a second angle ( 68 ) with the side wall ( 20 , 22 ) which is larger than the first angle ( 65 ).

4. The filter element according to claim 3 , wherein the holding element ( 36 ) in the functional position is aligned substantially perpendicular to the side wall ( 20 , 22 ).

5. The filter element according to claim 1 , wherein the holding element ( 36 ) has a female thread ( 38 ).

6. The filter element according to claim 1 , wherein the holding element ( 36 ) has a receptacle ( 70 ) for a pin ( 72 ) formed on the fastening element ( 44 , 78 ).

7. The filter element according to claim 1 , wherein the holding element ( 36 ) has a catch element ( 100 ) for a corresponding catch element ( 98 ) of the fastening element ( 44 , 78 ).

8. An air filter for a motor vehicle, comprising:
the filter element ( 10 ) according to claim 1 , wherein the filter element ( 10 ) is introduced into a receiving space ( 28 ) of a housing ( 12 ) of the air filter;
wherein a cover element ( 58 ) is secured to the housing ( 12 ) by fixing a fastening element ( 44 , 78 ) to the holding element ( 36 ) of the filter element ( 10 ) and wherein an insertion opening ( 52 ) of the receiving space ( 28 ) is closed by the cover element ( 58 ).

9. The air filter according to claim 8 , wherein the cover element ( 58 ) is configured as a separate closure mechanism for the receiving space ( 28 ) which is removable from the insertion opening ( 52 ) before taking the filter element ( 10 ) out of the receiving space ( 28 ).

10. The air filter according to claim 8 , wherein the housing ( 12 ) has a guide mechanism ( 54 ), wherein the holding element ( 36 ) is movable from the initial position into the functional position by introducing the holding element ( 36 ) into the one guide mechanism ( 54 ).

11. The air filter according to claim 8 , wherein the holding element ( 36 ) in the functional position engages behind a housing part ( 66 ) of the housing ( 12 ), wherein a passage opening ( 56 ) is formed in the housing part ( 66 ), and wherein a shaft part ( 42 , 84 ) of the fastening element ( 44 , 78 ) is guided through the passage opening ( 56 ) if the fastening element ( 44 , 78 ) is fixed to the holding element ( 36 ).

12. The air filter according to claim 11 , wherein the shaft part ( 42 , 84 ) has a screw thread ( 46 ) and/or a pin ( 72 ) introducible into a receptacle ( 70 ) by turning the shaft part ( 42 , 84 ).

13. The air filter according to claim 11 , wherein the shaft part ( 42 , 84 ) is pivotable about a pivot axis ( 82 ) extending perpendicularly to a longitudinal extension direction of the shaft part ( 42 , 84 ) and wherein by pivoting the shaft part ( 42 , 84 ) about the pivot axis ( 82 ), the fastening element ( 44 , 78 ) is movable into a release position in which fixation of the fastening element ( 44 , 78 ) to the holding element ( 36 ) is disengaged.
