Abstract
A seating furniture component, especially an upholstered furniture component with coupled backrest and seat adjustment, with a support chassis (2), with a backrest (4) adjustably attached to the support chassis (2), and with a seat (5) adjustably attached to the support chassis (2), as well as connection mechanism (6) for synchronous adjustment of the backrest (4) and seat (5) relative to the support chassis (2). The backrest (4) executes a tiltback and lowering motion relative to the support chassis (2) essentially as a pivoting motion around a pivot axis which is in the angle formed by the backrest (4) and seat (5) in front of the backrest (4) and above the seat (5). The seat (5) executes a corresponding but minor movement in the form of a superimposed sliding and lifting motion.
Claims18
Seating furniture component with coupled backrest and seat adjustment, comprising:
- a support chassis;
- a backrest adjustably attached to the support chassis;
- a seat adjustably attached to the support chassis;
- a connection mechanism connected between the support chassis, the backrest and the seat which comprises a means for synchronous adjustment of the backrest and seat in a manner causing the backrest to execute a superimposed tiltback and lowering motion relative to the support chassis from a highest upright sitting position into a lowest extended reclining position and the seat to execute a slight superimposed sliding and lifting motion from the sitting position to the reclining position;
- wherein a pivot axis is provided about which the backrest executes said tiltback and lowering motion as an essentially pivoting motion around said pivot axis which is in front of the backrest and above the seat within an angle formed between the backrest and the seat;
- and wherein said pivot axis is a virtual axis resulting from the connection mechanism comprising a plurality of connecting levers which produce the pivoting motion of the backrest.
Coupling brace for insertion between a support chassis of a backrest and seat of seating furniture having a coupled backrest and seat adjustment, said coupling brace comprising:
- a connection mechanism comprising a plurality of levers, each of which has coupling points on at least one of the support chassis, backrest and seat for producing a synchronous adjustment of the backrest and seat in a manner causing the backrest to execute a superimposed tiltback and lowering motion from a highest upright sitting position into a lowest extended reclining position relative to the support chassis as an essentially pivoting motion around a pivot axis which is in front of the backrest and above the seat at an angle formed between the backrest and the seat, while the seat executes a slight superimposed sliding and lifting motion from the sitting position into the reclining position;
- a support chassis mounting carrier which integrates all support chassis coupling points;
- a backrest mounting carrier which integrates all backrest coupling points;
- and
- a seat mounting carrier which integrates all seat coupling points.
