Abstract: The invention relates to a chair with adjustable seat depth, wherein the seat of the chair consists of a rigid seat support plate (1) and a sliding and ductile seat cushion plate (2), on which the seat cushion is arranged. The invention is characterized by the fact that the seat cushion plate (2) contains a flexible area (7), which forms a seat trough, that on the seat support plate (1) two lateral guide rails (8) are arranged, in which the seat cushion plate (2) can be displaced with guide ribs (6) that are incorporated in said plate and that between the seat support plate (1) and the seat cushion plate (2) a device (15) for improving the sliding characteristics, preferably a polyethylene foil that is coated with Teflon, is arranged. The chair is characterized by very good sitting comfort.

Abstract: The backrest of a chair comprises a frame (1), a backrest support (6) and a neck support (15). A membrane is clipped into the frame (1), and the backrest support (6) is articulated on a tilting mechanism. The frame comprises two side parts (2, 3) and two cross-pieces (4, 5), the lower cross-piece (4) lying at the height of the user's lumbar vertebra. The frame (1) and the backrest support (6) are interconnected in one piece. The component created as a result, is advantageoulsly a plastic injection moulding produced by the gas injection technique (GIT), and the plastic is a glass-fibre-reinforced polyarylamide. This overall structure of the backrest provides a high level of sitting comfort by elastic support of the back in all major regions and directions of movement, but at the same time also considerably reduces production, transport and assembly complexity and has an aesthetically impressive, distinctive form.

Abstract: A neckrest, for a chair having a backrest, is configured to be attached to a backrest shield in a height-adjustable manner. The neckrest includes a circular cross-section retaining rod, configured to be connected to the backrest shield via an articulated or movable connection so as to be tiltable by up to approximately 30° in a vertical plane vertically with respect to a surface of the backrest, and a circular cross-section guide sleeve, mounted on the retaining rod so as to be slidingly shiftable by up to approximately 200 mm on the retaining rod. The retaining rod includes a molding on a side thereof which is closest the backrest and seated in a housing having a recess. The molding has a round surface which slides under pressure on a polyurethane rubber material friction dampening device so as to achieve the articulated connection.

Abstract: In the case of a table with fold-away legs, the tubular legs (4) are connected in an articulated manner to articulation sockets (3) which are fastened on the underside of the table top (1). The articulated connection here is produced via a T-bolt (8) which has its crosspiece (23) mounted in a pivotable manner in the articulation socket (3), under the force of a spring (10), and which has its lower shank (26) screwed to a threaded ring (13) which has an external thread (21) of relatively large pitch, on which the tubular leg (4) can be moved by rotation in the longitudinal direction by means of a leg insert (14) fastened therein.

The position of the table flap is changed by use of a compression spring, which is movable in an arched guide slot.

Abstract: In the case of a chair with adjustable seat depth, the seat comprises a rigid supporting panel (1) and a single-piece, longitudinally flexible seat panel (2) which bears the seat cushion (3) and is connected in a longitudinally displaceable manner to the supporting panel (1). The longitudinal displaceability is achieved by providing guide strips (6) mounted in guideways (4) on the top side of the seat panel (2), the guide strips being fastened on the supporting panel (1) via screws (7), and the screws (7) passing through slots (5) on the base of the guideways (4). The supporting panel (1) is advantageously designed as a frame and consists of cast aluminium, and the seat panel (2) consists of polypropylene. This achieves an optimum sliding pairing.

Abstract: In the case of a neck support for a chair, the head cushion (6) is articulated, via an articulation bearing (5), on a guide sleeve (4) which can be displaced on a retaining bar (2), which is articulated on the top edge of the backrest (1) of the chair via a further articulation bearing (3), the retaining bar (2) and the guide sleeve (4) being of rectilinear design, this resulting in linear height adjustability of the neck support. The bottom articulation bearing (3) and preferably also the top articulation bearing (5) each comprise a cylinder (7) on the retaining bar (2) and two cylinders (8, 9) on the bearing foot (10) or on the link plate (26), it being possible for the first cylinder (7) to rotate in a controlled manner between the two second cylinders (8, 9) via blocks (13). In particular in combination with a height-adjustable backrest, the neck support according to the invention has an optimum adjustment range for the user's head and neck.

Abstract: In the case of a chair, in particular a swivel chair for the office, the armrest is made up of an armrest carrier, which comprises a carrier (1) and a sleeve (2) sliding thereon and is attached to the seat at the bottom by a seat flange (3) which can be displaced transversely to the seat direction, and of an arm support (10, 11), which can be displaced longitudinally via a guide (7) and can be rotated via a rotary part (4) mounted in a rotary bearing (5). The guide (7) is arranged parallel, but eccentrically in relation, to the axis of symmetry of the arm support. Since the rotatability of the arm support is at least 180°, it is possible to set different clear distances between the two arm supports (10, 11) of the chair.
