摘要： An item of seating furniture, in particular an office chair, having a pedestal with a support column on which a first rotational axis for a backrest is arranged which is pivotable between an upright starting position and a reclined resting position. The backrest is articulately connected in its lower region to a seat part, and when the seat part is in one piece, the articulatable connection is provided about a second axis.When the seating furniture is in the upright starting position, the second axis is arranged below the first axis. The rear seat part is non-rotatably connected to the backrest. The front seat part or the one-piece seat part is supported by kinematicsin relation to the carrying frame. The front seat part or the one-piece seat part is lowered relative to the rear seat part or the backrest by means of kinematics when the backrest is pivoted back.

摘要： A device for pivoting an object about a virtual axis by means of a kinematic system having a fixed base on which there is rotatably supported a first rotary component which has a first coupling component which rotates with respect to the base not in accordance with the rotary component, preferably not at all, characterized in that a second rotary component, constructed in a similar manner to the first, is connected to the first rotary component by means of the coupling components, whereby the portion thereof which in the case of the first rotary component corresponds to the base and which in this instance is the object carrier is rotated about the virtual axis.

摘要： Seating furniture, in particular, a chair having a plane of symmetry, a seat surface, a backrest, a kinematic arranged on a base of the seating furniture, which has a base arm, which is rotatable relative to the base around a base axis (A1), an end arm, which is rotatable around a base arm around an intermediate axis (A2), and a furniture part that is mounted to rotate around the end arm around an end axis (A3), where the three axes (A1, A2 and A3) intersect at a central point (Z, Z1). To achieve versatile mobility, the pivotable furniture part is the backrest, that the seat surface is mounted to rotate relative to the backrest around a connection axis running orthogonally to the plane of symmetry, and that the seat surface is connected to the base via a support kinematic that constrains at least one degree of freedom.

摘要： A virtual device for the limited pivoting of an object about a base virtual pivot point by means of a pivoting device, where a limiting device is provided for the pivoting angle. The virtual device is a mechanically stable and yet space-saving limiting device that is rotatable about an outer axis on the base and about an outer axis (23′) rotatable on the object, or on the slide, where the limiting device limits the distance and/or the angular position of the two axes relative to one another, with the proviso that the axes always occupy the same plane.
