Abstract: A reclinable office chair includes a reclination adjustment unit coupled to a bottom base disposed at the bottom of the office chair and having an angle limiting element disposed below and spaced apart from a connecting element abutting against carrying elements. When a user sitting on the office chair tilts the office chair in a predetermined direction, the connecting element and the carrying elements, whose movement is restricted by a rim of the bottom base, are stopped from tilting further as soon as the angle limiting element tilts to an extent to come into contact with the rim, not only allowing the office chair in operation to be tilted within a predetermined safety range in any direction, but also enhancing the anti-slip effect which takes place between the office chair and the floor.

Abstract: A furniture member may include a base frame and a seat assembly mounted on the base frame. The seat assembly may include a seat frame, a seatback, a seat bottom, a rocker member, a legrest mechanism, and a tilt mechanism. The rocker member is attached to the seat frame and rollingly contacts the base frame. The rocker member supports the seat assembly relative to the base frame such that the seat assembly is movable between a rocked-back tilt position and a rocked-forward tilt position. The legrest mechanism is mounted to the seat frame and attached to a legrest platform. The legrest mechanism may include a drive rod coupled to a pantograph linkage that is movable relative to the seat frame between retracted and extended positions. The tilt mechanism selectively locks the seat assembly in one of an infinite number of tilt positions between the rocked-back and rocked-forward tilt positions.

Abstract: In an aspect, the invention is directed to a chair that has a pedestal and an upper assembly including a body support assembly and a tilt control assembly. A biasing member is provided to bias the body support assembly towards an unreclined position. When the chair is empty the biasing member has a certain preload. When a person sits in the chair or when a downward force is applied to the upper assembly, there is relative movement between two chair components which causes an increase in the preload in the biasing member as compared to the preload when the chair is empty. As the downward force on the upper assembly increases, the preload in the biasing member increases.

Abstract: A seat assembly including a seat base, a back support, a support for the back support and/or for the seat base and at least one elastomer torsion-spring element. The back support and/or the seat base are/is pivotably hinged to the support in such a manner that a pivoting movement of the back support and/or of the seat base on a rotation axis can be carried out. During the respective pivoting movement of the back support and/or of the seat base with the elastomer torsion-spring element a restoring torque is generated that acts on the back support and/or on the seat base. The elastomer torsion-spring element includes an internal casing, an external casing encompassing the internal casing, and an elastomer body arranged in a space between the internal casing and the external casing. The elastomer body is rigidly connected to contact surfaces of the internal and external casings. The internal casing and/or the external casing are/is rotatably arranged on a rotation axis. During rotation of the internal casing and/or of the external casing on the rotation axis deformation of the elastomer body occurs. The contact surface of the internal or external casings include a non-circular cross section in a sectional plane perpendicular to the rotation axis.
