Abstract: In a tilt device for seat furniture, the base, which is fastened to the chair bottom part and which carries a rotatable backrest carrier for the backrest and a seat plate for the seat, is designed as a closed carrier box composed of a plurality of sheet-metal parts and is arranged between backrest cheeks of the backrest carrier. A simple compact construction of the mechanism, which can be used without appreciable changes for a permanent-contact backrest and for a simultaneous mechanism, is obtained.

Abstract: A compact, optically inconspicuous tilting device for seating units, to be attached underneath a seat including a casing disposed beneath a seat resting on the understructure of the seating unit, a seat carrier pivotably mounted about a horizontal axis to the front edge area of said seat, mechanical locking means for connecting the seat carrier within the casing including first locking members successively arranged in at least two planes parallel to the swivel axis of the seat carrier and staggered towards each other and second locking members engageable with said first locking members, a rest member connected to said casing including a shank member, a link member interconnecting said seat carrier with the shank member, a bearing member connected to said casing operably engageable with said shank member to the rest member, at least one spring element mounted on said casing which acts at one end of the seat carrier opposite to the load of the user, and bistable activation lever means for activating said mechan

Abstract: Disclosed is a standing work seat in which the support column and the base are rigidly attached together, the support column is inherently rotatable, the seat is inclinable in the seat direction. The seat exhibits a rear edge drawn up to the user's iliac crest, a rounded front edge and a slip-inhibiting configuration of the seat surface. The standing work seat permits optimum absorption of a user's body load in confined work stations.
