  • Patent number: 8673147
    Abstract: A container for the filtration of liquid is described, which has a cup and a cover mounted on the cup. The cup is at least partly filled with a filter material and has at least one outlet window for the liquid. The cover has at least one inlet window and at least one outlet window for air, wherein at least the windows have lattice-like structures with lattice openings. The air outlet window has at least one recess extending inward from the plane of the window, which is provided at least partially with at least one lattice structure.

  • Patent number: 7055850
    Abstract: The invention concerns a component (1) for motor vehicles, in particular, instrument panel, lateral covering or side member covering, comprising an airbag cover (2) arranged in the region of the filler channel (3) and having a weaker resistance zone opening when the airbag is inflated. The covering zone located on either side of the weaker resistance zone can move freely, from an extracted airbag, along a clearance path while remaining linked to the component 91), after the airbag has been inflated, in specific manner. The airbag cover (20) is an elastic material. The weakened resistance zone extends over the opposite delimitations (4, 5) of the filler channel 93), so as to ensure the extension and inflation of the airbag. Said device eliminates possible damage to the inflated airbag and injury risks incurred by passengers as result the burst parts projected coming from said cover.
