Filterelement, Innenraumluftfilter und Herstellungsverfahren

Ein Filterelement (1) umfasst einen Faltenpack (2) aus zickzackförmig gefaltetem Filtermaterial (3) sowie ein an dem Faltenpack (2) angebrachtes und das Faltenpack (2) zumindest teilweise umlaufendes und seitlich abstehendes Rahmenelement (5C, 14B, 15B, 16B). An dem Rahmenelement (5C, 14B, 15B, 16B) ist eine Rahmeneinrichtung (17) befestigt, wobei die Rahmeneinrichtung (17) als ein an das seitlich abstehende Rahmenelement (5C, 14B, 15B, 16B) angespritztes Kunststoffspritzgussteil ausgeführt ist. A filter element is provided with a pleated structure of a filter material folded in a zigzag shape. A frame element is attached to the pleated structure and at least partially circumferentially extends around the pleated structure. The frame element is air-permeable and laterally projects away from the pleated structure. A frame device is attached to the frame element. The frame device is an injection-molded plastic part injection molded onto the frame element. In a method for producing the filter element, an air permeable frame element is attached to the pleated structure of a filter material folded in a zigzag shape so as to circumferentially extend at least partially around the pleated structure and project laterally. The frame device is injection molded onto the frame element in an injection molding process. A filter assembly is provided with a filter housing and the filter element is received in the filter housing.
