摘要:
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.

The present invention relates to novel one-component polyurethane systems including one or more organic and/or inorganic compounds of vanadium in which the vanadium has an oxidation state of at least +4, to their preparation and use for preparing paints, inks and adhesives.
摘要:
The invention relates to a reactive composition containing A) an isocyanate-containing compound, B) a polyol, C) an organic tin or bismuth compound, D) a thiol group-containing compound or a polyphenol which is able to react with an isocyanate group in the presence of a tertiary amine as activator and with adjacent hydroxyl groups and E) a hydrolyzable halogen compound, wherein the molar ratio SH and/or OH:metal is 2 to 500 and the molar ratio halogen/metal is 0.05 to 10.
摘要:
The present invention relates to novel polysiloxane-polyether-based copolymers which contain T units and comprise randomly linked organopolysiloxane units and linear polyether units, to a method for their preparation and their use.
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.
摘要:
Aqueous coal slurries are prepared using aralkyl polyalkylene glycol ethers of the formula ##STR1## in which R.sup.1 represents an optionally substituted aryl radical,R.sup.2 and R.sup.3 are identical or different and denote hydrogen, alkyl or optionally substituted aryl,x represents a number in the range from 1 to 3,y represents a number in the range from 1 to 500, andR.sup.4 denotes hydrogen or one of the radicals ##STR2## in which M.sup..sym. represents a metal ion or ammonium,R.sup.5 denotes hydrogen, alkyl or optionally substituted aryl andR.sup.6 denotes hydrogen or alkyl, it being possible for the radicals R.sup.6 in the individual chain members of the polyalkylene glycol chain to be identical or different.
