Patent number: 7147288Abstract: The backrest of a chair comprises a frame, a backrest support and a neck support. A membrane is clipped into the frame, and the backrest support is articulated on a tilting mechanism. The frame comprises two side parts and two cross-pieces, the lower cross-piece lying at the height of the user's lumbar vertebra. The frame and the backrest support are interconnected in one piece. The component created as a result is advantageously a plastic injection molding produced by the gas injection technique (GIT) and the plastic is a glass-fiber-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.Type: GrantFiled: January 20, 2004Date of Patent: December 12, 2006Assignee: Sedus Stoll AGInventors: Klaus-Peter Grasse, Manfred Schlegel, Mathias Seiler

Patent number: 6948774Abstract: A chair, such as a swivel chair for the office, has an armrest that is made up of an armrest carrier, which includes a carrier and a sleeve sliding thereon and attached to the seat at the bottom by a seat flange which can be displaced transversely to the seat direction, and of an arm support, which can be displaced longitudinally via a guide and can be rotated via a rotary part mounted in a rotary bearing. The guide 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 1800, it is possible to set different clear distances between the two arm supports of the chair.Type: GrantFiled: August 21, 2003Date of Patent: September 27, 2005Assignee: Sedus Stoll AGInventors: Klaus Maier, Michael Klaesener, Thomas Stenzel

Publication number: 20050146178Abstract: A component for a stackable chair comprises a cuboidal basic body (1) which has two leg stubs (2, 3) on one longitudinal side and two crossmember stubs (4, 5) on its other longitudinal side. The two ends (6, 7) of the basic body (1) are bevelled in the forward and rearward directions at the sides, and noses (8, 9) which run parallel to the leg stubs (2, 3) are provided on the underside of the basic body (1), and channels (10, 11) are provided above the noses (8, 9), on the top side. The chair comprises two identical components of this type. If such a chair is stacked vertically on another, identical chair, then the bevelled ends (6, 7) of the basic body (1) have a centring effect and bring the chair into the correct position, with the result that the noses (8, 9) on the chair stubs (2, 3) enter into the channels (10, 11) on the top side of the basic body of the lower chair.Type: ApplicationFiled: July 16, 2003Publication date: July 7, 2005Applicant: SEDUS STOLL AGInventors: Harald Hergesell, Udo Hasenbein

Patent number: 6832814Abstract: 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.Type: GrantFiled: July 16, 2003Date of Patent: December 21, 2004Assignee: Sedus Stoll AGInventors: Thomas Stenzel, Michael Klaesener
