Abstract
A filter assembly includes an accordion fold pack made of filter material, which is sealingly joined to a retention frame. The retention frame has at its end face, at least on one side, a bracing whose length corresponds essentially to length of an end-face fold of the accordion fold pack extends the bracing essentially parallel to the direction of the end-face fold edge of the accordion fold pack and is arranged in the end-face fold. Disposed at the end face of the retention frame is a double sealing lip which extends in the direction of the end-face fold edge, as well as essentially parallel to the bracing. The double sealing lip is able to swivel about a film-hinge-type joint, and can be sealingly positioned with first sealing lip against end-face fold wall, and with second sealing lip against a boundary wall of a filter housing that faces the fold wall.
