Claims23
A vacuum cleaner filter bag with an inlet opening and a deflection device arranged in an interior of the bag at the inlet opening, wherein the deflection device is adhered or welded to a filter material of a wall of an inner portion of the vacuum cleaner filter bag, surrounding the inlet opening at least in part and wherein the deflection device is configured to deflect an air stream flowing through the inlet opening and for dividing the air stream into at least two partial streams with different flow directions.
A vacuum cleaner filter bag with an inlet opening and a deflection device arranged in an area of the inlet opening, wherein the deflection device is configured to deflect an air stream flowing through the inlet opening, the deflection device comprising a first position having a reduced extension size in relation to a second position extension size measured in a direction perpendicular to the plane of the inlet opening and wherein the deflection device comprises fold lines, so that the deflection device can be brought from the first or second position into the second or first position.
