Abstract: A tiltable chair in which a back rest is supported by at least one rear lever via a swivel joint and the seat is supported by a resilient, flexible front mounting element on a pedestal in such a way that when the back rest is tilted forwards or backwards the seat simultaneously partakes of an approximately horizontal, linear movement and the rear part of the seat partakes of a greater lifting or lowering movement than the front part of the seat.
Abstract: The invention relates to a table system in which at least two adjacent table elements can be releasably connected via their opposing table top edges with the aid of at least one mechanical connecting arrangement. Of the essentially two-part connecting arrangement a first main part contains a retaining lever which is built into the table top edge region of one table element and can be pivoted outwards, whilst the second main part of the connecting arrangement, built into the table top edge region of the adjacent table element, is constructed so as to receive the retaining lever form-lockingly and contains a securing element for the locking engagement between the first and second main parts. The assembly and disconnection of the individual table elements can be carried out quickly and reliably without additional aids.

Abstract: The invention relates to a variable seating arrangement with a plurality of seating elements which are supported by at least two approximately horizontal support elements (1, 1') the adjacent ends (1a, 1'a) of which are connected to one another in a common connecting column (4) and are pivotable relative to one another about a vertical shaft (6). In this way an extremely large number of arrangements and groupings of the seating elements relative to one another are possible.
Abstract: The invention relates to a device for sprung tilting movement of a component such as an inclining mechanism for a tiltable seat. The spring system is formed by at least one spring rod which is rotatably mounted in at least two bearings of which one bearing is stationary in the operating state while the other bearing is rotatable about an axis spatially offset relative to the axis of the spring rod. This results in a simple, light and space-saving construction.
Abstract: A chair which includes a seat portion and a backrest portion as well as a support member for supporting the seat portion. A cylinder piston assembly enables an adjustment of an inclination of the backrest portion with respect to the seat portion, the seat portion is mounted at the support member so as to fix a normal setting of inclination between the seat portion and backrest portion. A first end of the cylinder piston assembly is mounted to the backrest portion by way of a bearing shaft. The bearing shaft is mounted to the chair so as to enable the bearing shaft to be easily removed. A second end of the cylinder-piston assembly is connected to the chair by way of a coupling member which extends transversely of the seat portion. The coupling member includes a pair of axially spaced end portions in which are respectively arranged coaxially disposed bearings adapted to accommodate bearing support pins.

Abstract: A pedestal stool is disclosed having a base carrying a stem on which a seat portion is supported.The base includes a sand-filled, bulbous, ground-engaging bag or sack to enable the stool to be tilted at any angle and held at that angle by virtue of the change in shape of the sack in response to the resultant flow of sand which produces a new equilibrium position for the stool.
Abstract: The chair described has a single support leg carrying a support plate. An elongate member is pivotally secured to the support plate. A back rest is rigidly secured to the rear end of the elongate member while a seat portion bearing support is pivotally secured to the front end of the elongate member. Separate means are provided on the support plate to vary the inclination of the rear end of the elongate member, and therefore the back rest, and to vary the inclination of the bearing support and therefore the seat portion which it supports.
