| Zusammenfassung: | The bag (1) has an exterior wall (2) made of filter material i.e. multilayer fleece material, and comprising an inflow aperture (5). An inner bag is provided with a bag aperture (13) and arranged in an inner space of the bag. The inflow opening is formed at an angle of about 60-120 degree to the bag aperture in a blown-up state of the bag, where a part of airflow entering into the inflow aperture flows into the inner bag through the bag aperture. A piece of material (7) i.e. plastic film, arranged as an impact protection part is provided on an opposite side of the inflow aperture. |
