Abstract: A screw shaft attached to the upper rail is screwed into a nut member attached to the lower rail. When the screw shaft is rotated with respect to the nut member by a drive unit, the screw shaft is moved rearward and forward with respect to the nut member, and the upper rail is also moved rearward and forward with respect to the lower rail. A fixing nut is fixed to an inner surface of the lower rail behind the nut member, and a stopper bolt is fastened to the fixing nut from below the lower rail. When the upper rail moves forward, a stopper portion provided at a tip of the stopper bolt contacts the stopper plate to restrict an excessive forward movement of the upper rail.

Abstract: A vehicle seating system including a seat back, a seat bottom, a track arrangement, a first carriage, and a second carriage is for use within a vehicle. The seat bottom is coupled to the seat back. The track arrangement is configured to be coupled to the vehicle. The first carriage is coupled to the seat bottom and is moveable within the track arrangement. The second carriage is coupled to the seat back and is moveable within the track arrangement. The second carriage and the first carriage are releasably coupled to one another so the second carriage is moveable relative to the first carriage when the coupling of the first carriage and the second carriage is released. The position of the second carriage relative to the first carriage is substantially fixed when the coupling of the first carriage and the second carriage is locked.

Abstract: Wire being continuously drawn from a processing apparatus or other supply to a rotatably-driven take-up reel while the reel is being replaced is temporarily stored on a wire accumulator which is positioned, preferably temporarily, between the supply and the reel and which comprises an accumulator drum supported on a frame with one end free and means for rotatably driving the drum about its axis at any speed within a limited range of speeds. The accumulator drum carries means for continuously imparting tension to wire as wire is unwound over the free end of the drum.
