  • Patent number: 10960735
    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.

  • Patent number: 10737201
    Abstract: A filter system (100) has at least one filter element (10), a filter housing (108) having at least one first housing part and one second housing part, in particular a lid (110), as well as a coupling device (50). The coupling device (50) thereby has at least one first coupling part (60) and at least one second coupling part (70) that corresponds to it for removable coupling of the at least one filter element (10) to the second housing part (110). The first coupling part (60) has one or a plurality of first latching means (62) and control surfaces (64). The second coupling part (70) has one or a plurality of second latching means (72) that can be brought into operative connection with the one or a plurality of first latching means (62) and control surfaces (64).

  • Patent number: 10561969
    Abstract: A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.
