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

Patent number: 6857704Abstract: In a neck support for a chair, a head cushion is articulated, via an articulation bearing, on a guide sleeve displaced on a retaining bar, articulated on the top edge of a backrest via a further articulation bearing, the retaining bar and the guide sleeve being of rectilinear design, this resulting in linear height adjustability of the neck support. The bottom articulation bearing and preferably also the top articulation bearing each comprise a cylinder on the retaining bar and two cylinders on a bearing foot or on a link plate, it being possible for the first cylinder to rotate in a controlled manner between the two second cylinders via blocks.Type: GrantFiled: July 17, 2003Date of Patent: February 22, 2005Assignee: Sedus Stoll AGInventors: Thomas Stenzel, Michael Klaesener, Klaus Maier

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

Patent number: 6755472Abstract: 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.Type: GrantFiled: January 31, 2002Date of Patent: June 29, 2004Assignee: Sedus Stoll AGInventors: Thomas Stenzel, Michael Klaesener

Patent number: 6050646Abstract: A backrest, in particular for an office chair, is indicated, in which backrest a cover is stretched onto a frame. In order for it to be possible for the frame to be introduced into the cover in a simple manner, the frame is of hinged and rotatable design. The cover is stretched in the transverse and longitudinal direction by insertion of a transverse bow into the frame and fastening of the cover to the transverse bow.Type: GrantFiled: December 9, 1998Date of Patent: April 18, 2000Assignee: Sedus Stoll AGInventors: Thomas Stenzel, Michael Klaesener
