Clamping arrangement for seat carriers of chairs, in particular office swivel chairs, whereby the seat carrier is provided with at least two parts which can be pivoted in relation to each other about a common axis and to each of which a lamellar stack is hinged, whereby the lamellar stacks intermesh with each other, whereby both lamellar stacks are provided with recesses through which they are hinged to a common transverse pin, and the recesses of at least one of the lamellar stacks allow the lamellar stack to move across the axis of the common pin, and whereby means are provided which can be moved into and out of a clamped position with the lamellar blades of both stacks, whereby the clamping means are supported on one of the two parts or another additional part of the seat carrier, and a stop for the lamellar blades is provided in the seat carrier opposite to the clamping direction, whereby clamping means (9) are pivotably arranged in part (1), and its pivoting axis extends across the axis of the common pin (2), whereby means are provided for pivoting the clamping means (9) which extend outside the seat carrier and can be activated from outside, whereby furthermore in cross section, the clamping means have a contour which in axial direction of the common pin (2) has at least two different thicknesses, and whereby finally the clamping means are provided with at least two surfaces (15, 17) arranged at an angle to each other, one of which surfaces (15), when in clamped position, abuts to and clamps the lamellar blades (7) or a flange or collar acting upon said blades, whereby this one surface (15) constitutes the inner end of the thicker contour.
