Abstract

A cabin air filter is provided with a filter medium and a filter element frame that frames the filter medium and is configured to attach the cabin air filter to a filter housing. The filter element frame is provided with at least one engagement element configured to engage pivotably at least one receiving element of the filter housing for pivoting the cabin air filter relative to the filter housing about a pivot axis. The filter element frame also has at least one snap hook that locks with at least one locking element of the filter housing for blocking pivoting of the cabin air filter relative to the filter housing at least in a first direction about the pivot axis.

First claim

What is claimed is:

1 . A cabin air filter, comprising:
a filter medium; a filter element frame framing the filter medium and configured to attach the cabin air filter to a filter housing; the filter element frame including at least one engagement element configured to engage pivotably at least one receiving element of the filter housing for pivoting the cabin air filter relative to the filter housing about a pivot axis; the filter element frame further including at least one snap hook configured to lock with at least one locking means of the filter housing for blocking a pivoting action of the cabin air filter relative to the filter housing at least in a first direction about the pivot axis.

2 . The cabin air filter according to claim 1 , wherein the at least one engagement element is a guide element and the at least one receiving element is a guide recess.

3 . The cabin air filter according to claim 2 , wherein the guide recess comprises an open end for inserting the guide element and a closed end opposite the open end, wherein the closed end and the guide element interact with each other to define the pivot axis.

4 . The cabin air filter according to claim 1 , wherein the at least one snap hook is configured to lock with the at least one locking means upon pivoting of the cabin air filter about the pivot axis in a second direction opposite to the first direction.

5 . The cabin air filter according to claim 1 , wherein the filter element frame comprises two longitudinal profiles arranged parallel to each other and two transverse profiles arranged parallel to each other and arranged perpendicular to the two longitudinal profiles, wherein the at least one engagement element is provided on one of the transverse profiles.

6 . The cabin air filter according to claim 5 , wherein two of the at least one engagement element are provided, wherein each one of the two transverse profiles is provided with one of the two engagement elements.

7 . The cabin air filter according to claim 5 , wherein the at least one snap hook is arranged on one of the two longitudinal profiles.

8 . The cabin air filter according to claim 7 , wherein two of the at least one snap hook are provided and arranged on one of the two longitudinal profiles.

9 . The cabin air filter according to claim 1 , wherein the filter element frame comprises at least one groove configured to be engaged by a web of the filter housing.

10 . A filter assembly comprising a cabin air filter according to claim 1 and further including a filter housing, wherein the cabin air filter is attached to the filter housing.
