The invention relates to a holding plate (1) for a vacuum cleaner bag with a base plate (2) with an opening (3), a locking element (4) arranged on the base plate with a horizontal swing to close the opening, and a spring element (6) arranged in such a way that the bending angle (B) of the spring element with a horizontal swing of the locking element in the opening direction brings the locking element out of the first position, in which the opening (3) is sealed, into the second position, in which the opening is open, in a previously determined swing angle range that is smaller than the corresponding opening angle (x) of the locking element (4), in such a way that the locking element can be brought from the second position into the first position by the restoring force of the spring element in the direction opposite to the opening direction, and the spring element is located behind the locking element in the opening direction.
The invention relates to a vacuum cleaner filter bag (1) comprising an inlet opening (3), a retaining plate (4), which is situated on the exterior of the bag in the vicinity of the inlet opening and can be attached to a retaining device on a vacuum cleaner in order to fix the vacuum cleaner filter bag, and a sealing device situated in the vicinity of the inlet opening (3), which is configured in such a way that it adopts a first position when the retaining plate is not attached to the retaining device and a second position by the attachment of the retaining plate to the retaining device. The inlet opening is sealed in the first position of the sealing device (2) and is open in the second position of the latter.
The invention relates to a vacuum cleaner filter bag (1) with an inlet opening (3) and a deflection device (2) that is situated near the inlet opening (3), which is configured in such a way that the air stream flowing through the inlet opening (3) can be deflected.

NECK COMPRISING A DEFLECTION DEVICE FOR A VACUUM CLEANER
The invention relates to a neck (10) for a vacuum cleaner comprising a deflection device (1) and a connection device (11) for connecting the deflection device (1) to a connecting piece (20), which in turn connects a filter bag (13) to a suction pipe of the vacuum cleaner. The connection device (11) and the deflection device (1) are configured in such a way that the deflection device (1) is situated inside the filter bag (13) during the operation of the vacuum cleaner and that an air stream that enters the connection device (11) is deflected by the deflection device (1).

B01D 45/08 - Separating dispersed particles from gases or vapours by gravity, inertia, or centrifugal forces by utilising inertia by impingement against baffle separators
The invention relates to a vacuum cleaner filter bag. Said bag comprises an inlet opening, a deflection device, which is situated inside said bag in the vicinity of the inlet opening and is configured in such a way that an air stream entering the inlet opening can be deflected by the deflection device, and an air-permeable material layer, which is situated inside the vacuum cleaner filter bag, is connected at least at one point to said bag and has at least one part that is not connected to the vacuum filter bag and that encloses part of the edge of the material layer.
