Abstract: A spring link includes a link body which includes two side wall profiles which are parallel to one another at a distance and which are connected by a spring seat plate extending transversely from one side wall profile to the other side wall profile. Each side wall profile includes a side web having an outwardly directed upper collar section which extends in the longitudinal direction of the side web. The spring seat plate rests with a lateral longitudinal edge section on an upper collar section and is joined to the upper collar section. The side wall profiles of the link body are mirror-symmetrical to one another. The lower side of the link body opposite to the spring seat plate is open.

Abstract: A multi-layer sheet material having at least one topcoat layer of plasticized polyvinyl chloride and at least one outwardly facing layer of lacquer on the topcoat layer, where the topcoat layer of the multi-layer sheet material contains from 50 to 100 wt % of at least one polyvinyl chloride and from 0 to 15 wt % of at least one crosslinking aid suitable for radiation crosslinking, and a calcium hydroxide stabilizer and/or a Ca/Zn stabilizer having from 0.5 to 10 wt % of calcium and from 0.5 to 10 wt % of zinc. The multi-layer sheet material is radiation crosslinked.

Abstract: A multi-layer sheet material includes at least one textile substrate layer, at least one foamed layer made of polyvinyl chloride containing plasticizer, at least one cover layer made of polyvinyl chloride containing plasticizer, and at least one coating layer facing outward on the cover layer. The invention further relates to a method for producing the multi-layer sheet material and to an interior trim part made of a sheet material for a vehicle. For a reduced tendency to yellow under high-temperature aging and for greater color fastness, the polyvinyl chloride fraction in the cover layer is based at least 50 wt% on a polyvinyl chloride that was produced according to the method of suspension polymerization (S-PVC), and the composition for the cover layer comprises a calcium hydroxide stabilizer and/or a Ca/Zn stabilizer that contains 1 to 3 wt% calcium and 1 to 2 wt% zinc.
