  • Patent number: 11178972
    Abstract: A chair, in particular an office chair, has a seat inclination mechanism. A transverse strut of the seat inclination mechanism forms a spring device and this spring device has at least one torsion element. The seat inclination mechanism further has a basic support on which a backrest support and a seat element support are articulated. The transverse strut of the seat inclination mechanism forms a spring device. The transverse strut extends in the chair transverse direction and wherein the spring device has at least one torsion element, in particular a torsion bar spring. The torsion element, together with the basic support and/or the backrest support and/or the seat element support, is formed integrally, in particular in one piece, from plastic.

  • Patent number: 10499742
    Abstract: A mechanism for a chair is particularly suited for an office chair. In order to improve the sitting comfort of a chair, the mechanism has a base support to be placed on a chair column, a seat support disposed on the base support and movable in the longitudinal direction of the chair relative to the base support, and a backrest support which is connected to the seat support. The seat support includes first and second seat support elements. The second seat support element is movable transversely with respect to the longitudinal direction of the chair relative to the first seat support element and/or the backrest support includes first and second backrest support elements. The second backrest support element is rotatable relative to the first backrest support element about a rotational axis which lies in the longitudinal direction of the chair.

  • Patent number: 10076184
    Abstract: The invention relates to a frame furniture comprising a furniture plate (2) and two leg elements (4) supporting the furniture plate (2), said leg elements (4) being arranged on both sides of a vertical furniture median plane and being movably mounted. The frame furniture is characterized in that each leg element (4) can be moved between a normal position, in which the leg elements (4) are covered by the furniture plate (2), and an extended position, in which the leg elements (4) are uncovered at the top, in order to enable a stacking of the frame furniture via the leg elements (4).

  • Patent number: 10004335
    Abstract: The invention relates to a frame furniture comprising a furniture element (14) being plate-shaped at least in some areas and having an at least partially nearly horizontal extension and being arranged on a carrier frame (18) which has a leg element (20A, 20B) on both sides, respectively, regarding a vertical furniture median plane, the leg element (20A, 20B) consisting of a tubular element bent in such a way that the tubular element forms a front and rear furniture leg (22A, 22B, 24A, 24B). The tubular elements each have an elliptical or oval cross section having a long major axis and a short minor axis, wherein the major axis and the minor axis intersect with the vertical furniture median plane over the length of the particular tubular element at an angle less than 90°.

  • Patent number: 9839296
    Abstract: A mechanism for an office chair is structurally particularly simple and consequently comparatively inexpensive, but nevertheless extremely variable. Both the seat support and the backrest support are articulated by way of a common pivot axis. The seat support is connected in an articulated manner to the base support by way of at least one pivot bolt and is pivotable relative to the base support. The backrest support is connected in an articulated manner to the base support by way of the at least one pivot bolt and is pivotable relative to the base support.
