Definitions
- the invention relates to seating furniture, in particular an office chair according to the preamble of claim 1.
- a disadvantage of the known seating furniture of this type is the fact that it is comparatively complex.
- the invention is based on the object of making seating furniture of the type presupposed as known particularly easy to manufacture from a few parts and at low cost.
- the design of the coupling element as a spiral spring has the result that this spiral spring has a spring function and a lever function at the same time, that is to say it can perform mechanical forced coupling between the backrest support and the seat.
- the double function of the spiral spring makes such seating furniture lighter, simpler and less expensive than the known seating furniture of the type presumed to be known.
- a seat support 2 is fastened on the central chair column 1 and has a front area consisting of two parallel webs 2a, on which the seat 3 is mounted so as to be pivotable about a pivot axis 3a.
- a backrest support 4 is pivotally mounted about a pivot axis 4a.
- the backrest support 4 carries a backrest 5.
- a connection is made by means of a spiral spring 6 between the seat 3 and the backrest support 4.
- the backrest support 4 consists of two parallel areas, which have at their ends receptacles for the ends of the arms 6b of the spiral spring.
- the arms 6b are pivotally attached to the two parallel legs of the backrest support 4 about the axes 4b.
- the arms 6b of the spiral spring 6 extend obliquely outwards and upwards to an offset along the axis 3b.
- the axis 3b is formed by corresponding recordings of the horizontal area of the spiral spring 6.
- These receptacles or storage areas 3 c are attached to the underside of the seat 3.
- this cranked area 6a is supported at the rear end of the seat support 2 behind the chair column 1 by resting there. It is easily possible to adjust the spring hardness by an additional adjusting screw, not shown, which can be adjusted is supported on the one hand on the cranked area 6a and on the other hand on the seat support 2.
- the movement of the backrest support is transmitted to the seat 3 via the arms 6b.
- the spiral spring 6 is thus simultaneously a coupling element for the movement and a spring element.
- spiral spring is used as a generic term for various types of springs, all of which can be used in the invention.
- the spiral spring can be a torsion spring, for example.
- leg spring it is possible to design the spiral spring as a leg spring, the windings being able to extend around the axis 3b.
- simple leaf springs as spiral springs, which are clamped rigidly at the articulation points 4b and 3b, for example.
