摘要:
Materials based on gypsum and organic additives are improved if they contain polyethers and, if desired, polymers. They can be used in a wide range of areas, for example as slabs in the building sector and for improving plasters, mortars, insulating materials and other construction compositions, casts and/or moulds.

To produce mouldings for screening against electromagnetic radiation it is highly advantageous to use metal fibre-containing composite materials as obtained by impregnating a bundle of continuous metal filament fibres with a polymeric adhesion-promoting substance, sheathing the resulting compact precursor with a thermoplastic matrix and cutting the resulting extrudate of composite material into defined lengths.The composite materials can be used as such or together with thermoplastic granules.

The present invention relates to a vehicle pedestrian protection airbag arrangement (7) comprising an airbag (9), a housing (8), an inflating device (10) and a lid (11), the airbag (9) being arranged to be inflated by the inflating device (10) in the case of a collision with a pedestrian when the airbag arrangement (7) is mounted in a vehicle (1). The lid (11) has a first side (11a), facing away from the housing (8) and a second side (11b), facing the housing (8) when the lid (11) is mounted against the housing (8). The housing has a front wall and a rear wall, in which housing the airbag is stored before inflation. The airbag arrangement (7) further comprises at least one attachment means (12a, 12b, 13a, 13b) running between the lid (11) and at least one other part (8, 9) comprised in the airbag arrangement (7). When the airbag (9) is inflated, it is at least partly positioned between the lid (11) and the housing (8).
摘要:
A vehicle seat includes a seat frame, a first air-bag unit and a second air-bag unit. The seat frame is at least partially covered by a padding material and substantially covered by a cover. The first air-bag unit includes a first air-bag mounted within an outboard side of the seat, and substantially covered by the cover. The second air-bag unit includes a second air-bag mounted within the outboard side of the seat and substantially covered by the cover. The first air-bag is configured to inflate and burst through the cover, when activated, and to bear against an occupant of the seat sitting in a normal position in the seat, thereby exerting a pushing force against the occupant in an inboard direction. The second air-bag is configured to inflate and burst through the cover when activated, and to occupy a position between an occupant of the seat and an exterior side wall of the vehicle.
