Claim:
A seating apparatus, comprising: a seat frame provided for affixing the seating apparatus to a floor; a seat base mounted on the seat frame; a seat base bearing unit separate from the seat base for mounting the seat base on the seat frame in a movable manner relative to the seat frame; a backrest unit separate from the seat base and coupled to the seat frame, wherein the seat base bearing unit comprises at least one stiffening means provided for stiffening the backrest unit, the stiffening means being movably mounted relative to the seat frame, wherein the stiffening means includes a pivot axis about which the stiffening means rotates and at least two coupling points oriented in a transverse direction relative to the seat base bearing unit, and wherein movement of the stiffening means about the pivot axis effects a movement of the seat base relative to the seat frame and vice versa; and a back rest kinematics unit coupled to the coupling points of the stiffening means and connected to the seat base for inclining the backrest unit relative to the seat frame, wherein the seat base is movable in a forward direction if the backrest unit is moved from an essentially upright position to a rearwardly inclined position.
