Abstract: The present invention relates to an adjusting device for vehicle seats having a threaded spindle (4) and a spindle nut arranged thereon, each of which is connected in an axially immovable manner with one or the other of elements (1, 2) to be adjusted relative to each other. The spindle nut (13) is provided with a full-length (or continuous) channel (20) running parallel to the threaded bore which receives the threaded spindle (4), which channel receives a bar (22) which prevents a rotation of the spindle nut (13) about the longitudinal axis of its threaded bore. The opposing boundary surfaces (21) of the channel (20), which cooperate with the bar (22) are spaced from each other such that at the midpoint of the channel (20) the space is equal to the bar thickness and uniformly increases toward the two ends of the channel.

Abstract: Knitted outerwear slacks produced of thermoplastic fibers, of permanently finished natural fibers, or of a thermoplastic and natural fiber blend. Both legs of the slacks are of seamless tubular knitted fabrics shaped by molding and terminated on one or both ends in a double welt, the legs being connected together by one seam in the crotch portion.The invention also relates to a method of producing knitted outerwear slacks of thermoplastic fibers, of permanently finished natural fibers, or of a thermoplastic and natural fiber blend. The method comprises knitting on a medium diameter circular knitting machine two seamless tubular knitted fabrics one after the other, the circumference of the machine being equal to one trouser leg circumference, the trouser legs having a double welt. Said tubular knitted fabrics are separately heat-molded on individual molds to the final shape of the trouser legs.
