Abstract
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.
Claims37
An article of seating furniture having a plane of symmetry, comprising:
- a base of the seating furniture;
- a seat surface, where the seat surface is optionally divided into a rear seat surface part and a front seat surface part, such that either the single seat surface or the front seat surface part is connected to the base via a support kinematic that constrains at least one degree of freedom;
- a backrest attached to the single seat surface or the rear seat surface part;
- and
- a main kinematic, arranged on a base of the seating furniture;
- the main kinematic having:
- a base arm that is rotatable relative to the base around a base axis;
- and
- an end arm that is rotatable around the base arm around an intermediate axis;
- wherein the main kinematic carries the backrest so that it is pivotable, and the backrest is mounted so as to be rotatable around the end arm around an end axis;
- an
- the base axis, the intermediate axis, and the end axis draw near to one another in a central area;
- wherein the seat surface is rotatable relative to the backrest around a connection axis running orthogonally to the plane of symmetry;
- or
- the front seat surface part is rotatable relative to the rear seat surface part around a seat division axis running orthogonally to the plane of symmetry.
