Abstract: The invention relates to a backrest with a support area (71), at least one structure connected to the support area (71) or forming the support area (71), which structure (10) extends towards the top of the backrest from a first end region of the support area (71) to a second end region of the support area (71) and at the front has a tension element (49) and at the rear a pressure element (47). The tension element (49) connects the first end region (37) of the support area (71) to the second end region (38) of the support area (71) transmitting tensile forces. The pressure element (47) connects the first end region (37) of the support area (71) to the second end region (38) of the support area (71) transmitting thrust forces. Pressure element (47) and tension element (49) are in the extension direction non-displaceably connected to one another in the first and in the second end region of the support area (71).

Abstract: A work chair has columnar armrest carriers, which normally serve for the uptake of an armrest. On at least one side of the work chair, however, armrest carrier bears a handbag instead of an armrest. This handbag has a pocket, for example, in which the armrest carrier can be engaged. Alternatively, an armrest or an armrest carrier may be provided with features for carrying a handbag, portable telephone or the like.

Abstract: A task chair has a buttocks portion, with a size sufficient only for the bottom of a person sitting on it, and a thigh support separate from it. The thigh support is displaceable to at least partway under the buttocks portion and can be pulled forward while under the buttocks portion. As a result, the length of the seat surface can be adjusted to the body size of a person using the stool. The guide for the displacement is curved. The front edge of the buttocks portion is formed by padding that tapers in wedge-like fashion. The front part of the cushion rests on the thigh support, and the rear part is retained by a bearing shell. The buttocks portion can be designed to be pivoted together with the backrest.

Abstract: In a table (11), the tabletop (19) is divided into three parts (21, 22, 23), of which one (23) is fixedly connected to the frame (13) of the table (11), the second (22) is articulated on the first (23) by a joint (27) and the third (31) is in turn articulated on the second (22) by joint (25) and is adjustable as to height. Together with an arm (29) pivotally fixed on the frame (13) and on the height-adjustable tabletop part (21), the movable tabletop part (22, 21) and the frame (13) form a parallelogram. The angle .alpha. of the parallelogram is adjustable with a lever (31) on the middle tabletop part (22) and by a motor (33) with a spindle (35). The height of the table is thus adjustable.

Abstract: To permit backward rocking of the back or back-and-seat of a chair, independently of the previously tilted-back position of the chair, a comfort position memory structure is provided which includes a manually adjustable variable stop structure formed by a cam curve (37) with a serrated or toothed surface, engaged by a stop element (41) coupled to the seat (17, 19). The cam (37) is manually rotatable, by being secured to an externally user-accessible adjustment segment (45). To set a predetermined tilted position, the user tilts back on the chair, and then permits the chair to tilt forward to a comfortable position, and then rotates the manually engageable segment (45) until a tooth (39) of the cam disk (37) is engaged by the stop (41). A spring (32) biasses the chair forwardly and against the stop, unless tilted back by the user.

Abstract: To simplify the construction of a tilting chair, typically a desk chair, in which the seat (2) and chair back (7) tilt together, the chair back (4) has an extension or attachment arm (5) extending from the lower region thereof to a zone adjacent or beneath the seat (2), and a pivot positioned at, or below the seat pivotably connects the attachment arm (5) to the seat, so that the pivotable attachment of chair back and seat is placed close to the hip joint of a user of the chair. The attachment arm has an extending portion (5') which is connected by a guide element, in the form of a double-link lever (10') or a guide slit (10) to the support structure (2), the guide means being connected to the attachment arm, for example by a cross bolt (9) which, preferably, also serves as one attachment pivot of a positioning and force spring (7), preferably a gas spring which is pivotably connected (8) at its other end to the support structure (1).
