摘要： A seating furniture component with coupled backrest and seat adjustment, having a support chassis (1), a backrest (2) and a seat (3) adjustably attached to the support chassis (1), with the backrest (2) and seat (3) being movably joined to one another in the area of the vertex of the angle between them, the backrest (2) being coupled to a pivot axis (4) on the support chassis (1) at a distance above the vertex of the angle, and the seat (3) being movably attached to the support chassis (1) near the front edge of the seat (3) by a support mechanism (5, 6). The backrest (2) executes a superimposed tiltback and lowering motion from a sitting position into a reclining position, relative to the support chassis (1), while the seat (3) executes a slight superimposed sliding and lifting motion in a synchronized manner. The connection of the backrest (2) to the seat (3), in one embodiment, has two connecting axes on each side which run in two slotted cranks as connecting axis and slotted crank pairs, a first of the connecting axis and slotted crank pairs being located on the rear edge of seat (3), the backrest (2) extending to the rear edge of the seat (3), and the second connecting axis and slotted crank pair being located on the rear edge of seat (3) at a distance above the first pair.
