Filter apparatus, vehicle, use and method

A filter apparatus comprising:

• a filter element having a filter medium body and a frame surrounding the filter medium body, wherein the frame comprises two opposing lateral surfaces;
• a plurality of engagement elements;
• and
• a filter housing comprising two opposing wall sections, at least one of the wall sections comprising at least one engagement counter element in which one of the plurality of engagement elements is configured to be accommodated, wherein the at least one engagement counter element defines a groove in the wall section of the filter housing;
• wherein the groove comprises an insertion section which permits an insertion movement of the one of the plurality of engagement elements substantially along a throughflow direction and a locking section extending from the insertion section at an angle with respect to the insertion section;
• and
• wherein the one of the plurality of engagement elements is disposed on one of the lateral surfaces of the frame of the filter element and extends away from the filter medium body;
• further comprising a holding sections connected to the one of the plurality of engagement elements and disposed in a recessed area of the filter medium body in an assembled state, and wherein the recessed area of the filter medium body is accessible from a side of the filter element from which the filter element is mounted in the filter housing.

• further comprising a holding section connected to the one of the plurality of engagement elements and, in an assembled state, engaging at least partially around or behind the filter element on an inflow side or on an outflow side or on an upstream edge or on a downstream edge of the frame.

A method for mounting a filter element in a filter housing using a plurality of engagement elements, wherein the filter element comprises a filter medium body and a frame surrounding the filter medium body, wherein the frame comprises two opposing lateral surfaces, wherein the filter housing comprises two opposing wall sections, at least one of the wall sections comprising at least one engagement counter elements in which one of the plurality of engagement elements is adapted to be accommodated in a positive fitting manner, wherein the engagement counter element is configured as a groove in the wall section of the filter housing and comprises an insertion section which, permits an insertion movement of the engagement element substantially along a throughflow direction, and a locking section connected to the insertion section and angled with respect to the insertion section, and wherein at least one of the lateral surfaces of the frame of the filter element has at least one through opening which, in an assembled state of the filter element in the filter housing, lies opposite the locking section, and wherein, in the assembled state, the one of the plurality of engagement elements engages through the through opening and positively engages in the locking section of the groove of the engagement counter element, wherein the method comprises:

• a) inserting the filter element into the filter housing;
• and
• b) arranging the engagement element on the lateral surface of the filter element such that the engagement element extends away from the filter medium body and is positively held in the locking section.
