Definitions

• the invention relates to a vacuum cleaner filter bag comprising a bag wall and a holding plate connected thereto, which can be connected, in particular brought into engagement, with a holding device of a vacuum cleaner.
• Vacuum cleaner filter bags are today mainly made of nonwovens. Due to their excellent dust holding capacity, vacuum cleaner filter bags made of nonwovens have virtually replaced filter bags made of paper. The production of filter bags made of nonwovens is fundamentally different from the production of paper bags. Common are rectangular flat bags, which are formed from an upper and a lower side wall, which are welded together at the edge. Such filter bags are known, for example, from DE 201 01 466, EP 0 161 790, EP 0 639 061, EP 1 059 056 or EP 1 661 500.
• the vacuum cleaner filter bags are usually distributed several times folded in a carton. In the folded state, the vacuum cleaner filter bags are then inserted by the consumer in the designated space of the vacuum cleaner. Since the space of the vacuum cleaner usually in at least one spatial direction has a smaller extent than the vacuum cleaner filter bag, the filter bag in the space can often develop insufficient. As a result, the filter bag may under certain circumstances unfold its capacity insufficient. On the one hand it can happen that not all areas of the side walls are flowed through evenly. As a result, the data passage speed can increase and the separation efficiency of the filter bag decreases. On the other hand, not so much space can be available for the storage of the dust particles.
• the service life of the filter bag may decrease, since the pressure drop of the bag increases rapidly and thus the volume flow which is conveyed through the vacuum cleaner drops relatively quickly. Inadequate deployment also reduces the usable volume available for receiving dust. A partially unfolded bag can hold correspondingly less dust, the bag must be changed earlier.
• the invention provides a vacuum cleaner filter bag comprising a bag wall and a holding plate connected thereto, which is connectable, in particular engageable, to a holding device of a vacuum cleaner, characterized in that the vacuum cleaner filter bag additionally comprises a fastening device through which a part of the bag wall of the vacuum cleaner filter bag in Operation of the vacuum cleaner is fixable in at least one spatial direction.
